METHOD AND APPARATUS FOR PRODUCING POWER GAS
Technical Field
The invention relates to a method for producing power gas, in particular for internal combustion engines .
The invention also concerns an apparatus for realizing the method according to the invention.
Background Art
Number of cars with internal combustion engines shows an ever increasing tendency. These types of cars are operated with petroleum derivates, petrols with different octane number, res . diesel f el. However, petroleum sources have become finite, at the same time by-products of combustion are contaminating the environment. Several solution have been elaborated for reducing environmental damages, however operation is taking place continuously by using petroleum derivates . In such a manner environmental contamination can be reduced only, however complete elimination is impossible. Cars with power gas have been also known with which gaseous media are used instead of liquid fuels for operating the engine.
However, cars with engines with gas-based opera¬ tion have not spread in a wide circle. In this case operation is performed with gases on carbon basis, accordingly problem of environmental contamination could no_t be solved at all .
Aims set for the present invention lie in to develop a method for the substitution of traditional fuels in course of which, by using natural materials
SUBSTITUTESHEET
gaseous media can be produced which are well suitable for driving engines with internal combustion.
Disclosure of the Invention
The invention is based on the recognition that in nature several materials are available, which - when reacting with water - are able to develop gaseous media forming explosive gas, at the same time by- products arising in course of gas formation are innocuous for the environment, as well being suitable for further processing. Such a gas-forming material is calcium carbide .
A further aim set lies in to develop an apparatus being suitable for the performance of the solution according to the invention.
The aim set will be realized by the performance of a process in course of which the material available in nature tending to gas formation, when brought in contact with water; in a controlled space of reaction it is allowed to contact with water, using the adequate quantity, thereby gas is formed; the gaseous medium thus obtained will be collected in a tank, said tank is connected to an internal combustion engine; gas is burnt in the engine compartment and energy having been realised in course of combustion will be utilized in this way.
In course of an advantageous mode of realization of the process according to the invention, water is allowed to react with calcium carbide, acetylene gas thus formed is used for producing energy which is well suitable for supplying energy to the motor with internal combustion based on gas-operation.
S U BST ITUTESHE
In course of an alternative mode of realization of the process according to the invention control of reaction takes place by sensing differential pressure by using a separate control uni .
The aim set for the invention will be attained so, insofar we use an apparatus which has a reaction space connected to a water-tank and a fuel tank collecting the gaseous medium produced, while water supply to the reaction space is controlled by means of a control-unit functioning on basis of differential pressure. 0 With a preferred embodiment of the apparatus according to the invention the water-tank is provided with a tank for additives, whereas both the water tank and the tank containing additives is provided with a level-controlling unit, sensing the level of liquid and 5 actuated by the control-unit, at the same time the fuel-tank is formed as a pressure-tight vessel.
With another preferred embodiment of the apparatus according to the invention the reaction-space is connected to a cassette containing the material taking * ** part in gas formation, preferably calcium carbide, operated via the control unit and provided with a feeder, * above the controlled feeder there is tight- woven net atomizing the water coming from the water- tank through a water-pipe as well as a pressure sensor, 5 furtheron there are means actuated by the control unit for the discharge of the byproduct Ca(OH2) i.e. lime milk arising in course of reaction, from the reaction space. The cassette receiving calcium carbide is preferably air-tight and it is made of some synthetic ° material .
With a further preferred embodiment of the apparatus according to the invention the duct interconnecting the reaction space and the control unit
is provided with a rectifying element having been connected to the control unit .
Method and apparatus will be detailed by the example of an advantageous mode of performance resp. of a preferred embodiment with reference to the figure enclosed.
Brief Description of Drawing
Figure 1 is the diagram of the apparatus according to the invention.
Best Mode of Carrying out the Invention
Essentially the apparatus according to figure 1 consists of the 1 water-tank, the 4 reaction space interconnected with the 8 fuel-tank receiving the gas as well as of the 15 control unit controlling gas formation. There is a cassette 5 provided for made preferably of some synthetic material, closed in an air-light way, connected to the reaction space, con¬ taining material ready for gas formation - calcium carbide ' - and provided with a feeder.
In the reaction space, above the 5 cassette there is a 11 net distributing the water coming through the water pipe and reacting with 6 calcium carbide fed from the cassette 5 into the 4 reaction space.
Furtheron, 4 reaction space is provided with a 19 level switch staying in an actuating connection with the 15 guiding unit as well as with means for the discharge of the by-product Ca (OH) 2 arising in course the reaction between water and calcium carbide (not illustrated here) .
SUBSTITUTESHEET
For the sake of order it should be mentioned that removal of the by-product formed in course of reaction can be realized in such a manner too, that by-product is left as long in the cassette 5 still the whole quantity of calcium carbide has been discharged, thereafter by exchanging the cassette 5, simultaneously the by-product is also removed.
Gaseour medium formed in the 4 reaction space is led into the 8 fuel tank through the 7 gaspipe connected to the upper part of the 4 reaction space, said fuel tank is formed from a pressure-tight vessel.
In the gas-pipe the 10 rectifier is arranged actuated by the 15 control unit.
From the 8 fuel tank gas is led through the 9 pipe to the place of utilization, that means practically that the 8 fuel tank is connected through the 9 pipeline to the motor with internal combination based on gas-operation. In the water-tank there is the 14 tank for additives arranged. Both the 1 water tank and the 14 tank for additives are provided with the 17 and 18 level switches actuated by the control unit, while 17 level switch senses 12 water level in the 1 water tank and 18 level switch senses liquid level in the 14 tank containing additives.
In course of the process according to the invention water is led from the 1 water tank through the 2 pipeline into the reaction space 4. In the 4 reaction space water reacts with 6 calcium Carbide (CaC) fed into 4 reaction space from the 5 cassette. Acetylene gas - C 2 H2 - formed arrives into the 8 fuel
SUBSTITUTESHEET
tank through the pipeline delivering gas. By means of the 15 control unit the whole process is kept under surveillance. In the 4 reaction space gas formation is continued as long as 8 fuel tank is completely filled.
Function of the system is based on the following parameters :
In course of reaction between water and calcium carbide
CaC 2 + 2H 2 0 = C 2 H 2 +Ca(OH) 2
acetylene gas - C 2 H 2 and lime milk Ca(OH) 2 are formed.
Acetylene gas thus formed is utilized, preferably for driving motors with internal combustion, while lime milk formed is led from the 4 reaction space into an exchangeable tank. Lime milk can be utilized for different purposes, so e.g. for water softening.
Gas thus formed has a normal temperature and it is most explosive. On ignition the gas-mixture containing 5 to 80 % acetylene and air explodes with a high intensity.
Control of the system is based - as mentioned before - on basis of the pressure p r of the 4 reaction space and the pressure prevailing in the 8 fuel tank
Pf •
Namely control is based on the formula
Pr = Pf Said requirement is met by means of the 10 rectifier arranged in the gas-delivering 7 pipeline interconnecting the 4 reaction space and the 8 fuel tank.
S U BS TITUTESHEET
10 rectifier actuates 3 valve of the 2 water pipeline, in such a manner quantity of water arriving into the 4 reaction space will be well controlled.
In case, if pressure values having measured on both sides of the rectifier
Pr Pf process will be continued as long as pressures are equalized.
In accordance with the aforementioned, if on both sides of the 10 rectifier of the gas delivering 7 pipeline p r = pf, the circuit will be closed. In case, if pressure in the 4 reaction space is higher, than the pressure prevailing in the 8 fuel tank, i.e. Pr Pf< tne 15 control unit opens the 3 valve, accordingly gas formation in the 4 reaction space starts .
Taking into consideration that in this case "gasforming itself" is taking place, we must select the single components of the system with utmost care, prescriptions relating to safety must be strictly kept. In * respect to the water tank there are no special requirements, it should be made of some flexible material or of some synthetic material.
The task of the 14 tank containing the additives lies in to ensure constant quality of water needed for gas formation, so for example at an external temperature of +3 C° it should supply anti-freeze solution into the i water tank.
In case of—the 4 reaction space one has to proceed with maximal safety, it is considered as advantageous if the reaction promoting tank does not include welded joints, .but it should be made by using deepdrawing technology.
SUBSTITUTESHEET
Preferably the 8 fuel tank is formed as a pressure- -tight vessel. In this tank we store C 2 H 2 formed in the 4 reaction space.
It is also possible to compress the gas, in the case the pressure-tight vessel should be modified according to requirements .
Returning to control, the 15 control unit is operated by the 21 current source and it is connected via its leads to the parts of the apparatus. In the following cases the 15 control unit stops the process immediately:
a) if in the 5 cassette there is no CaC at all b) if quantity of water is not sufficient c) if liquid level in the 14 tank containing additives is too low.
Control of process is always performed by means of the 19 level-switch. The advantage of the apparatus lies in that it is not at all restricted to the embodiment specified here, in dependence of utilization and final use it can be transformed. Acetylene gas formed can be used where ever with motors with internal combustion supplied as fuel for the motor not depending on the output of the motor.
In case of use in cars it seems to be expedient to drive the car with liquid acetylene gas, a further advantageous feature lies in that it meets all require¬ ments of ecology.
