[37] As shown in FIGS. 1 to 6, the pyrolysis oil recovery system in accordance with the present invention includes a recovery chamber 100 into which a large amount of combustion heat from a combustion heat inlet port is introduced, a recovery furnace 200 installed in the recovery chamber and configured to perform pyrolysis of the waste material introduced thereinto, a waste material supply means 300 for supplying the waste material through a side surface of a pyrolysis gas discharge port formed along an upper end of the recovery furnace, a residue discharge means 400 installed in front of the recovery furnace and configured to discharge combusted residue, and a condenser 500 connected to the pyrolysis gas discharge port to condense the introduced pyrolysis gas into a liquid state
[38] The recovery chamber 100 is divided into upper and lower halves 100a and 100b, and flanges are formed at both halves to be assembled to each other by fastening bolts
to form a closed drum structure. Here, as shown, the upper and lower recovery halves 100a and 100b have a dual structure and include an insulating material disposed therebetween to prevent heat loss to the exterior.
[39] Coupling holes 140 are formed at an upper end of the upper recovery chamber 100a to install pyrolysis gas discharge pipes 210, disposed from a front part to a rear part of the system at predetermined intervals, such that the pipes pass through the upper recovery chamber. A combustion heat discharge port 130 is formed at one position adjacent to a rear and of the upper recovery chamber 100a to discharge the circulated combustion heat. In addition, holes for axially coupling a cutting rotary 230 are formed at front and rear ends of the upper recovery chamber 100a.
[40] Further, a combustion heat inlet port 110 is formed at one position adjacent to a front end of the lower recovery chamber 100b to supply a large amount of combustion heat generated from a burner. Furthermore, a combustion heat induction pipe 120 is formed at an inner end of the combustion heat inlet port 110 to guide the large amount of combustion heat to a front end of the recovery furnace 200 (200a and 200b) to be described later so that a portion of the combustion heat is circulated throughout combustion heat circulation pipes 220, and the other is discharged into the recovery chamber 100 (100a and 100b) to be circulated therethroughout. In addition, holes for axially coupling a conveyance screw 240 are formed at front and rear ends of the lower recovery chamber 100b. Further, an entrance 150 is installed at a front end of the lower recovery chamber 100b to allow entry of persons, and the entrance 150 has an opening/closing plate 160 for closing the entrance 150 using a bolt when it is not used.
[41] The recovery furnace 200 divided into upper and lower halves 200a and 200b has flanges formed at the halves to be assembled to each other by fastening bolts, thereby forming a closed drum structure.
[42] In a state in which fastening holes 260 are formed at an upper end of the upper recovery furnace 200a in a longitudinal direction thereof at predetermined intervals, the pyrolysis gas discharge pipe 210 is adhered onto the fastening holes 260 to be fastened using bolts. In addition, three cutting rotaries 230 are axially installed in the upper recovery furnace to pass through front and rear ends thereof to cut or scatter the waste material input through the pyrolysis gas discharge pipe 210.
[43] Further, straight combustion heat circulation pipes 220 are installed in the lower recovery furnace 200b at predetermined intervals in a lateral direction thereof to circulate the external combustion heat therethroughout. Furthermore, a conveyance screw 240 is axially installed under the lower recovery furnace 200b to pass through the front and rear ends to convey the waste material input into the recovery furnace 200a and 200b and then pyrolyzed therein to the residue discharge means 400, which is to be described.
[44] Here, each of the upper and lower recovery chamber halves 100a and 100b and the upper and lower recovery furnace halves 200a and 200b may have a hemispherical or trapezoidal shape, and in particular, the trapezoidal halves may be coupled to form a hexagonal drum structure. More particularly, when the lower recovery furnace 200b has the trapezoidal structure, an arcuate bottom plate 250 may be further formed to smoothly discharge the waste materials through the conveyance screw 250.
[45] In addition, the cutting rotaries 230 and the conveyance screw 240 have rotary shafts exposed to the rear end of the recovery chamber 100a and 100b. The rotary shafts are coupled to sprockets, and the sprockets are coupled to a sprocket of a motor (not shown) via a chain to integrally rotate them. Further, as shown in FIG. 1, a passage 600 is provided around the recovery chamber 100a and 100b to allow persons to pass therethrough. Meanwhile, a conveyor 700 is installed at one side of the waste material supply means 300 to continuously supply a waste material through a hopper. Furthermore, in order to prevent deformation of or damage to the recovery chamber due to a large amount of combustion heat, a separate cooling water circulation structure is provided, and a water tank 800 is further provided to supply water into the cooling water circulation structure.
[46] In the meantime, the waste material supply means 300 is in communication with a side surface of the pyrolysis gas discharge pipe 210 to supply the waste material conveyed by the conveyor 700 into the recovery furnace 200a and 200b.
[47] Specifically, the waste material supply means 300 includes a horizontal pipe horizontally extending from one side of the pyrolysis gas discharge pipe 210 by a certain length, and a vertical pipe vertically extending from an end of the horizontal pipe so that the waste material can be supplied from the hopper. Here, a pusher 320 is installed at the end of the horizontal pipe to reciprocate depending on operation of a cylinder 310 to push the waste material into the pyrolysis gas discharge pipe 210. In addition, an introduction preventing plate extends backward from an upper end of the pusher 340 to prevent introduction of the waste material from the vertical pipe, thereby preventing loss of a pyrolysis gas. Here, the horizontal pipe may have a guide groove to improve support power and sealing performance, in a state in which the introduction preventing plate of the pusher 320 is inserted thereinto.
[48] The residue discharge means 400 has a cylindrical structure installed under the recovery chamber 100a and 100b to be in communication with a portion of a lower surface of the front end of the recovery furnace 200a and 200b. Here, a discharge screw 410 is installed in the residue discharge means 400 to be closely rotated therein. The discharge screw 410 is rotated by a motor separately installed at the exterior.
[49] In the discharge means 400, the discharge screw 410 divides an inner space of the discharge means 400 in plural to slowly discharge the residue, thereby preventing the
hot residue from rapidly contacting the external air to cause fire.
[50] The condenser 500 is coupled to the pyrolysis gas discharge pipe 210 installed at the upper end of the recovery furnace 200a and 200b to cool a pyrolysis gas and extract pyrolysis oil. Therefore, the condenser 500 generally circulates coolant to liquefy the pyrolysis gas into a liquid state.
[51] While few exemplary embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes may be made to these embodiments without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
