THE SYSTEM OF TREATING ODOR AND HAZARDROUS GAS WITH
ROTARY REGENERATIVE HEAT EXCHANGER AND ITS APPARATUS
Technical Field
The present invention relates to a harmful material
treatment system for which recovers the energy and removes
the harmful material in the process of treating gas
containing the harmful material generated in the multiplex
utilization facility, the display mall, diverse
manufacturing processes and the vehicle painting process,
more particularly, to a harmful material treatment system,
which can recover the energy contained in the air
conditioning facility or in the exhaust gas of the process
with an efficiency of more than 90%, for exhausting the
inside air to the outside so as to treat the contaminating
material such as odor and volatile organic chemicals (VOCs) ,
and simultaneously remove the harmful material with a high
removal efficiency of more than 90% by adsorbing and
concentrating the harmful material with a rotary-type adsorbent .
Background Art
In general, a rotary-type heat exchanger is employed
to perform the heat exchange in facilities requiring a
large-sized air conditioning device, such as a multiplex
utilization facility, a habitation facility, and an event
mall, and the like. In such facilities, thermal energy
contained in the air exhausted to the outside is transferred
to thermal energy storing elements at one side of the
rotary-type heat exchanger and recover it at the opposite
side to thereby recover the thermal energy.
However, nowadays, recognition about the material
causing the sick-house syndrome has been increased in the
habitant and the multiplex utilization facilities, and there
occurs a problem that harmful material generated from the
manufacturing process of the factory has made the work
environment badly off to thereby reduce the productivity, so
that cleaner life environment and factory working
environment are required.
However, according to the conventional rotary-type
heat exchanger, it is possible to recover the energy, but it
is impossible to treat the harmful material introduced from the outside and the harmful material exhausted to the
outside. Whereas, with regard to the method for treating the
harmful material exhausted to the outside from the building
or the factory, there are several methods such as an adsorption treatment method using activated carbon, a direct combustion method for removing it through combustion, a heat accumulating combustion method, and a catalyst combustion method, and the like, and there are also several methods for treating it by using microbes, and the like.
However, according to such diverse methods, although it is possible to remove the harmful material to be exhausted, it is also impossible to recover the thermal energy contained in the gas exhausted from the inside to the
outside, resulting in a loss in the thermal energy.
FIG. 1 is a view for showing a conventional rotary- type heat exchanger disclosed in the US patent NO. 4,542,782. Referring to FIG. 1, the air flow exhausted with high temperature is effected in such a manner that heat is accumulated at one side of the heat exchanger through the rotary-type heat exchanger, and then is moved to the other side of the heat exchanger while being rotated to perform the heat exchange with the gas introduced from the outside to thereby recover the thermal energy. However, for such a method, there is a problem that the harmful material contained in the exhausted air cannot be removed.
FIG. 2 is a view for showing another example of the
conventional rotary-type heat exchanger disclosed in Korea Patent Laid-Open Publication No. 2002-0033353. In FIG. 2, there is shown a rotary-type heat exchanger with a cleaning sector, which can improve the cleanliness of the indoor air by purifying the air backward-flowed toward the inside among
the exhausted air to make it flow into the indoor.
However, this type of the heat exchanger is to prevent the backward-flow of the air contained in the inside space of the medium of the heat exchanger in the process of the conversion of the heat exchanger from the exhaust region to the suction region, by providing the cleaning sector at a
boundary region between the suction region and the exhaust region of the heat exchanger for making a portion of the
exhausted air purified and flowing into the suction region.
In this regard, there is no element for adsorbing the harmful material in the heat exchanger. Further, with regard to the cleaning method, it is constructed that the air received in the heat exchanger can be naturally exhausted by means of the pressure differential by closing one side of the cleaning sector and fluidically communicating the other side with the flow passage toward the exhaust fan.
However, with regard to this structure, there is also
produced a problem that it is impossible to treat the harmful material exhausted to the outside and several contaminating material contained in the outside air flowing
into the inside.
Disclosure Technical problem
Therefore, the present invention has been made to solve the problems occurring in the conventional arts, and the primary object of the present invention is to provide a harmful material treatment system, which can adsorb and treat the harmful material exhausted from the inside to the
outside or from the outside to the inside of the heat exchanger separately or treat them by means of a catalyst
directly, not to mention the heat exchange, by making the rotating heat exchanger from material with adsorption and catalyst property for removing the harmful material and with high thermal energy storage and heat exchange capacities .
Another object of the present invention is to provide a harmful material treating system, which can accomplish the
heat recovery of more than 90% of the exhausted energy and concurrently removing the harmful material with a removal percentage of more than 90% by using one treating system.
Still another object of the present invention is to
provide a harmful material treatment system, which can
adsorb and treat the harmful material by providing
additionally the heat exchange function to an exhaust source
incapable of adsorbing the harmful material due to the high
temperature of the exhaust gas from the exhaust source.

rotating the rotary-type rotor.
Also, to attain the technical subject of the present
invention, there is provided a harmful material treatment
system, which is configured to regenerate thermal energy,

exchange medium having functions of adsorbing the harmful
material and storing the thermal energy concurrently, and a

chemicals, or the harmful material/ and rotatable
distribution plates with a plurality of openings mounted
respectively at the heat exchange medium portion, so that
respective regions of the heat exchange medium defines
separate flow passages to allow the inflow of the outside
air and outflow of the inside air.
In addition, the present invention may further comprise
heating means for heating the desorption air flowing into the concentration and desorption region.
Also, the desorption of the harmful material in the
concentration and desorption region of the rotary-type rotor is carried out by the radiation of ultra-violet rays, by means of a sound wave or pressure reduced air.
In the present invention, the rotary-type rotor may further comprise a cooling region disposed between the concentration and desorption region and the suction region
for cooling the heat exchange medium heated for desorption. In this instance, the outflow air exhausted from the cooling region is preferable to flow into the concentration and desorption region.

use any one material selected from the group consisting of
cordierite having a high thermal energy storage function, bending-type ceramic sheet, alumina, silica, polymer resin, aluminum, stainless, asbestos, and natural fiber, or a

Best Mode
Hereinafter, most preferable embodiment of the present
invention will be explained in detail with reference to the
appended drawings .
In the specification explained hereinafter, the term of
Λ heat exchange medium' is used to represent that it performs
not only the heat exchange simply, but it performs the adsorption of the harmful material concurrently. In the
present invention, the term of ^thermal energy storage' is
used in place of the term of λ heat exchange medium' for the
medium designed to perform the heat exchange only.
FIG. 3 is a basic conceptual view showing a harmful material treatment system, which is configured to store and recover the thermal energy by using a rotor, according to a preferred embodiment of the present invention. In FIG. 3, a rotary-type rotor 1 of the present invention comprises a heat exchange medium 400 and a receiving portion 500 for the heating exchange medium for supporting it. A region in which the heat exchange medium 400 exists is divided into a suction region 2, an exhaust region 3, and
a concentration and desorption region 4. The heat exchange
medium contains adsorption material for removing the harmful material by means of adsorption or reaction, and is comprised of thermal energy storage material with high thermal energy storage amount.
In the present invention, a specified portion of the
heat exchange medium 400 is transported to the suction region 2, the concentration and desorption region 4, and the exhaust region 3 in order sequentially by means of the
rotation of the rotary-type rotor 1.
For convenience's sake in representing, a rotation shaft of the rotary-type rotor 1 is not shown, and it will
be the same in the other embodiments to be described below.
The outside air, which has been flown into the suction
region 2 according to the rotation of the heat exchange
medium 400, recovers the thermal energy stored in the
exhaust region 3 with an efficiency of more than 90%, and
the harmful material adsorbed by the heat exchange medium in
the exhaust region 3 is detached in the concentration and
desorption region 4, so that it is possible to treat the
harmful material economically by treating the harmful
material with enriching more than one times the existing
concentration .
As for an adsorption material for adsorbing and
treating the harmful material in the present invention, one
kind of material selected from the group consisting of
zeolite, activated charcoal, activated carbon fiber, alumina,
silica, photo-catalyst, and low-temperature oxidation
catalyst, and a composite material made by combining at
least two kinds selected from the group can be used.
Furthermore, with regard to the thermal energy storage
material, one kind of material selected from the group
consisted of ceramic material such as cordierite, bending- type ceramic sheet, alumina, silica, and the like, polymer
resin (urethane resin, polyethylene resin, polypropylene
resin, and the like) , aluminum, stainless, activated
charcoal, natural fiber (palm fiber, pine fiber, hinoki-
fiber, wool, cotton, ski- fiber, momi-fiber, buna-fiber,
elm-like tree fiber) , and asbestos, or a composite material
made by combining such material selected from the group can
be used.
The structure of the heat exchange medium 400 is a low-
pressure loss type structure of honeycomb type, bending-type,
or a net shape structure, or it can be used with forming the
material into predetermined shape and then filling it.
The rotation direction of the rotor is as denoted by
the arrow, so that the heat exchange medium 400 of the
exhaust region 3 is converted sequentially into the exhaust
region 3 → concentration and desorption region 4 → suction
region 2 → exhaust region 3, according to the rotation of
the rotor, so that heat exchange function and the harmful
material removing function can be performed.
When the temperature of the air exhausted from the
inside is high, the thermal energy contained in the gas
exhausted from the inside is derived by the heat exchange
medium 400 in the exhaust region 3, and the harmful material is adsorbed by the heat exchange medium 400, so that the
purified gas can be exhausted to the outside.
In this instance, the heat exchange medium 400 storing
the thermal energy and adsorbing the harmful material in the
exhaust region 3 is transported to the concentration and
desorption region 4. Then, the transported heat exchange
medium 400 is detached in the concentration and desorption
region 4 by using temperature, pressure, photo energy, or
sound wave energy, and is transported through a separate
routine to thereby be exhausted to the outside by means of
separate treating means, which can treat the harmful
material.
In this instance, the gas purified by the treating
means can be re-circulated into the exhaust region 3. Also,
the volume of the air flowing into the concentration and
desorption region 4 for the desorption is smaller than that
of the air passing through the exhaust region 3, and it is
desirable, so far as the volume of the air becomes smaller.
In general, it is preferable to be 1/5 to 1/20. In this
instance, it is necessary to cope with the desorption time
and method properly so that there can be no energy loss
stored in the heat exchange medium 400 during the desorption.
If the desorption time is too long, or if too high temperature is required for the desorption, energy loss can
be occurred. Thus, the heat exchange medium 400 removed of
the harmful material in the concentration and desorption
region 4 is transported to the suction region 4 again, and it emits the energy stored in the rotary-type rotor 1 to transfer it to the air to be sucked. Also, the harmful
material contained in the sucked air are adsorbed by a surface of the rotary-type rotor 1, resulting in the removal of them.
The heat exchange medium 400 passing through such processes is transported to the exhaust region 3 at last,
and such process continues as long as the system is operated. If the treating system of the present invention is employed, it is possible to obtain the high heat recovery percentage of more than 90% and the harmful material removal percentage of more than 90% of the conventional thermal energy storage
type heat exchanger.
Mode for Invention
FIG. 4 is a basic conceptual view showing another example of a harmful material treatment system, which is configured to store and recover the thermal energy by using a rotor, according to the present invention. In the present example, a cooling region 9 is further formed between the concentration and desorption region 8 and the suction region
6. According to this embodiment, when the concentration and
desorption process is to be performed to remove the harmful
material adsorbed at the concentration and desorption region
8 by using the thermal energy, the thermal energy added for
performing the desorption is recovered to be flowing into
the inside progressively.
In this instance, the cooling region 9 is formed to
reduce the amount of the thermal energy flowing into the
inside, and the temperature of the rotary-type rotor 5 is
maintained to be low in the suction region 6, so that it is
possible to better adsorb and treat the contaminating
material flowed in from the outside to the inside.
FIG. 5 is a view showing another embodiment of the
harmful material treatment system, which is configured to
store and recover the thermal energy by using a rotor,
according to the present invention.
In FIG. 5, it is constructed that the heat exchange
medium is divided into a thermal energy storage medium 13
with which the heat exchange medium performs the function of
heat exchange, and an adsorption medium 14 with which the
heat exchange medium performs the function of removing the
harmful material .
Such structure can be applied to a case in which it is
difficult to adsorb the harmful material because the
temperature of the gas exhausted from the inside to the
outside is high. The exhaust gas with high temperature can
perform the function of heat exchange in the thermal energy
storage medium 13 for performing the heat exchange, and is
flowing into the adsorption medium 14 at low temperature to
remove the harmful material easily.
With regard to the physical adsorption property of the
adsorbent, the adsorption is well performed at the low
temperature and is not performed well at the high
temperature. In general, it is preferable to set the
adsorption temperature of the zeolite, and the activated
charcoal to be below 50 ° C.
However, the rotary-type rotor 51 of the present
invention can be used with combining the thermal energy
storage medium 13 with the adsorption medium 14 in serious,
or with adding or coating the adsorption medium 14 on the
surface of the thermal energy storage medium.
Furthermore, it is possible to change the arranging
order of the adsorption medium and the thermal energy
storage medium, and to arrange them with more than one pair.
In other words, it can be constructed in the order of
"thermal energy storage medium - adsorption medium - thermal
energy storage medium", or "adsorption medium - thermal
energy storage medium - adsorption medium". Also, the rotor
can be constructed of more than two sets of the combination
described above.
FIG. 6 is an example of an embodiment according to the
present invention, in which the energy is recovered and the
indoor air is purified in the multiplex using facility such
as a large display mall. The air exhausted from the large
display mall 26 is flowing into the exhaust region 17
through an exhaust line 37. Depending on the circumstances,
a portion of the gas exhausted through circulation air
conditioning means 41 is made to circulate again.
By means of the gas flowing into the exhaust region 17,
the harmful material produced in the display mall 26 is
adsorbed on the surface of the rotary-type rotor 15 located
at the exhaust region 17, and the energy exhausted from the
indoor to the outside is transferred to the rotary-type
rotor 15.
Then, the rotary-type rotor 15 is rotated to progress
into the concentration and desorption region 20. In this
instance, additional energy is applied to remove the harmful material attached on the surface of the rotary-type rotor 15
located in the concentration and desorption region 20, the
energy being detached by desorption means 21.
With regard to the desorption energy added at this
stage, desorption means 21 using the temperature, the
pressure, and the combination of them can be used. In
general, a detaching method using the thermal energy
produced by increasing the temperature is employed.
Furthermore, photo energy (UV) , and microwave can be
used as desorption methods. Thus, the detached gas can be
treated by means of removing means 22 for the harmful
material. With regard to the removing means 22 for the
harmful material, an adsorption method using a general
adsorbent, an adsorption method using adsorbents, a
combustion system using combustion (direct combustion,
catalyst combustion, thermal energy storage combustion,
thermal energy storage and catalyst combustion,
concentration combustion) , a biological treating method
employing microbes can be used.
Also, a photo-catalytic device and a low-temperature
oxidation catalytic device can be used, when the
concentration of the exhaust gas is low. When the photo-
catalytic device or the low-temperature oxidation catalytic device are to be used, the rotary-type rotor can be used by
coating the surface thereof with the photo-catalyst and the
low-temperature oxidation catalyst, after removing the
removing means 22 for the harmful material.
The purified gas decomposed by the removing means 22
for the harmful material is exhausted to the outside through
a blower 25. The rotary-type rotor 15, which has removed the
harmful material at the concentration and desorption region
20, is transported to the suction region 16 with retaining
the thermal energy only. The transported rotary-type rotor
15 heats the outside air flowed in by a suction fan 23 to a
predetermined temperature and make it flow into the inside
of the display mall 26.
In this instance, the rotation speed of the rotating
rotary-type rotor 15 is preferable to be under three
revolutions per minute in consideration of the durability of
the device, although it is preferable so long as it is fast.
FIG. 7 shows another embodiment of the present
invention, in which the present invention is applied to a
vehicle painting process, and the like.
In such a case, the gas containing volatile organic
chemicals produced in the painting process is exhausted at a
high temperature above 80 ° C. If the temperature of the exhausted gas is so high, the removing percentage decreases
rapidly because the harmful material such as the volatile
organic chemicals contained in the exhaust gas is not well
adsorbed to the adsorbent such as zeolite, or the activated
charcoal, and the like.
In such a case, if the system suggested by the present
invention is applied, it is possible to operate the removing
means 22 for the harmful material by means of the combustion
heat of the harmful material exhausted by adsorbing and
concentrating the harmful material with the rotary-type
adsorbent together with recovering the thermal energy of
high temperature. It can be explained as follows more
concretely.
The harmful material produced from the painting process
36 is exhausted to the outside through the exhaust line 40.
The exhaust gas is at first flowing into the exhaust region
29, and then the heat exchange and the adsorption of the
harmful material are performed concurrently, and is
exhausted to the outside through the exhaust fan 34. In this
regard, the heat exchange is carried out at the front of the
rotary-type rotor 27, and the adsorption of the harmful
material is carried out at the back thereof. Accordingly,
the rotary-type rotor can be constructed of material for performing the heat exchange principally at the front
portion thereof and material for performing the adsorption
at the back portion thereof in principal . The rotary-type
rotor 27, which has carried out the heat exchange and
adsorption in the exhaust region 29, is transported to the
concentration and desorption region 30, in which the
temperature is increased by means of a detachable burner 31
using a portion of the exhaust gas to thereby remove the
harmful material in the rotary-type rotor 27 using the
thermal energy. The rotary-type rotor 27, which has removed
the harmful material in the concentration and desorption
region, is moved to the suction region 28 to thereby
transfer the heat to the outside air flowed in by the
suction fan 33 to heat the sucked air, and is moved to the
inside of the painting process .
FIG. 8 is a conceptual view showing the system using
the rotary-type rotor according to the present invention.
The system comprises a rotary-type rotor 44 and a casing 45
for receiving it. The system employs a system, in which the
casing 45 is fixed and the rotary-type rotor 44 is rotated
to thereby convert the air flow path. While a rotation shaft
and driving means for rotating the rotary-type rotor 44 are
not shown separately, it can be easily designed by referring to FIG. 10 to be described below by those skilled in the art
of the technical field to which the present invention
pertains .
While, FIG. 9 is a conceptual view showing a system
using distribution plates according to the present invention,
in which distribution plates 47, 49 are arranged for
converting the flow path at the front portion and the back
portion thereof to produce an effect identical with that of
the rotary-type rotor without using the rotary-type rotor
separately.
When the rotary-type rotor is used, it is possible to
reduce the damage and wear of the machine due to the load of
the rotor, and to change the numbers of revolution to
thereby better improve the heat recovery percentage.
Furthermore, an air inducing conduit 113, and a plurality of
opening portions or conduits 61, 62, 63, and 64 can be
designed to define the flow passage between the heat
exchange medium portion (represented by numeral 48 for
denoting the heat exchange medium and the casing integrally)
and the distribution plates 47, 49. The conduits comprise an
inflow opening 62, an exhaust opening 61, a desorption
opening 63 and a desorption conduit 64.
It is possible to form the shape of the air inflow conduit 113 to be tapering, so that a portion joining with
the heat exchange medium 48 becomes large and a portion
joining with the distribution plates 47, 49 becomes small to
thereby reduce the diameter of the distribution plates 47,
49. Also, it is possible to reduce the size of the rotating
distribution plates to thereby reduce the power expense
relative to the gas leakage and the driving.
FIG. 10 is an exploded perspective view showing an
example of the harmful material treatment system using the
rotary-type rotor of the present invention.
Referring to FIG. 10, the treating system comprises
substantially an inside conduit portion 200, a rotary-type
rotor 100, and an outside conduit portion 300.
As for the rotary-type rotor 100, the rotary-type
rotors as described above can be employed. As shown in the
drawings, the rotary-type rotor 110 is comprised of a heat
exchange medium 112 divided into a plurality of regions 115,
116, 117, and 118, and a receiving portion 120, and is
rotated by driving means such as a motor 150, a speed-
reduction gear 152, and a driving shaft 140. The rotation
shaft of the rotary-type rotor 110 has not been shown. In
the present system, the driving means, the speed-reduction
gear 152, and the driving shaft 140 can be mounted at the inside of the casing 120.
The inside conduit portion 200 comprises separation
plates 210, 212, 214, 216 for separating several inlet and outlet flow passages and conduits 220, 222, 224, and 226 added to respective flow passages of the regions divided by
the separation plates .
The inside air flowed in through the inlet conduit 220 of the inside conduit portion progresses through the exhaust region 116 of the rotary-type rotor to be exhausted to the
outside through the outlet conduit 320. In this instance, the adsorption and thermal energy storage operation of the harmful material is produced in the exhaust region 116. The exhaust region 116, which has performed the operation of the adsorption and thermal energy storage is rotated to the
desorption region by means of the rotation of the rotor, and the desorption operation can be produced by the air flowed in from the inlet conduit 324 for the desorption air. The desorbed air is exhausted to the outside through the outlet conduit 324 for the desorption air. In this instance, the
inlet air for the desorption can be heated .by means of heating means such as a burner, and the like for facilitating the desorption.
Thus, when the inlet air is to be heated, it is preferable that a cooling region is formed in the heat exchange medium, as shown in the drawing. This is because,
if the heat exchange medium is at excessively high temperature, the adsorption operation cannot be performed
easily when it returns to the exhaust region again.
The detached heat exchange medium 112 is rotated to
progress into the cooling region 118, and is cooled by the cooling air flowed in from a cooling air inlet opening 326. The cooled air is exhausted through the cooling air outlet conduit 226. Since the cooling air is at higher temperature relative to the outside air, it is possible to reduce the energy for heating the air flowing into the desorption air inlet conduit 224 by forming a flow passage between the cooling air outlet conduit 226 and the desorption air inlet
conduit 224 and recycling it.
Then, when the heat exchange medium progresses into the suction region 115 by the rotation of the rotor, the outside air is flowed in through an outside air inlet opening 322 to pass through the suction region 115. In this instance, it
flows into the inside of the rotor through the outside air outlet opening 222 after recovering the thermal energy stored in the heat exchange medium in the suction region 115. In the embodiments of the present invention as described above, it is preferable to perform sealing at the boundary of the respective region of the exhaust region, the
suction region, the desorption region, and the cooling
region, so that the air is not to be mixed. It is preferable
to use heat resistant material such as silicon rubber,
teflon, and the like as proper sealing material. The sealing
can be accomplished by providing sealing material at proper
position of the distribution plates between the distribution
plates and the heat exchange medium, or at the separation
plate between the separation plate and the heat exchange
medium.
While the present invention has been described with
reference to the preferred embodiments, the present
invention can be performed in various forms without
departing from the spirit or principal features . Accordingly,
the above embodiment is only illustrative in all respects,
and should not be construed to limit the present invention.
