Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a fuel gas generation device for internal combustion engines of automobiles, ships, etc., which significantly increases gas generation efficiency.
The purpose is to miniaturize the entire device and improve its practicality.

Various proposals have been made regarding the use of hydrogen gas in combination with, for example, LPG gas or petroleum-based fuel as fuel for internal combustion engines.

For example, the invention disclosed in JP-A-50-70737 is an example of this, in which a DC generator is activated by the rotation of an engine, and the generated electrical energy is guided into an electrolytic reaction tank where water is decomposed and reacted. The idea is to generate hydrogen gas and supply it to the combustion chamber of the engine together with a well-known oil-based fuel such as gasoline.Although it is excellent in principle, the hydrogen gas obtained from the electrolytic reaction tank described above is Since the amount of electrolytic reaction is very small and the capacity of the electrolytic reaction tank is quite large, it is completely unsuitable for use in automobiles and has not reached the level of practical use.
In the device disclosed in No. 21727, there is a straight metal anode potential tube inside the container body, a metal cathode potential tube located in the center, and a metal cathode potential tube inserted into the container body. A heat generating heater is installed, and the above metal anode
An amount of water is supplied into the decomposition chamber formed between the cathode 15-electrode and both potential tubes, and the water is thermally decomposed to produce hydrogen gas, which is then pumped into the engine cylinder along with gasoline. It is designed to supply air. However, in the case of the above-mentioned method, the amount of gas decomposed is not only small because the electrolytic surface area in contact with the water in the decomposition chamber is small, but also a large number of bubbles adhere to the surfaces of both potential tubes during decomposition. Not only does this adversely impede the decomposition efficiency, but also the caustic sorb produced during decomposition
Various impurities such as dust and moisture remain in the decomposition chamber, which hinders decomposition efficiency and makes it difficult to withstand long-term use.
There were problems such as the need to perform separation cleaning within a relatively short period of time to remove impurities. 90 The present invention is a result of undeveloped research aimed at overcoming the various drawbacks of the prior art described above. Specifically, it includes a long electrolytic tube for decomposing water into hydrogen and oxygen, and The electrolytic tube consists of a means for circulating the electrolytic solution, a means for replenishing water at any time by the amount reduced when the amount of the electrolytic solution decreases, and a booster device for cleaning the gas decomposed in the electrolytic tube. The whole is spirally wound to have a cathode potential side, and in the center there is an electrode rod on the anode side along the longitudinal direction, and the spiral electrolytic tube is placed in the water tank mentioned above. It is characterized by the fact that it has been installed.

The specific contents of the device of the present invention will be explained below based on illustrated embodiments. 1 is an electrolytic tube, 9 is an electrolyte tank, 13 is a water tank, 16 is a replenishment water tank, 23 is a first booster, and 26 is a A second booster is shown respectively.

The entire electrolytic tube 1 is spirally wound to have a cathode potential side, and has an electrode rod 2 on the anode side running along its longitudinal direction in the center as shown in FIG. is held in place with a non-conductive space ring 4 interposed therebetween.

6 and 7 indicate conducting wires, one of which is connected to the electrode rod 2K via a rubber gasket 5, and the other to the electrolytic tube 1 itself. Further, the helically wound electrolytic tube 1 is inserted in its entirety into a water tank 13, and the upper end of the electrolytic tube 1 is connected to the tube 8 from the upper part of the water tank 13, and the lower end thereof is inserted into the water tank 13.
The pipes 12 extending into the pipes 3 are connected to each other using appropriate pipe joints. The electrolytic solution tank 9 is filled with electrolytic solution until it reaches a certain water level, and is replenished with water when the electrolytic solution decreases. Electrolytic tube 1 through 12
6 through the hollow part 3 of the electrolytic tube 1 into the tube 8
Then, it is returned to the electrolytic solution tank 9 and the circulation is constantly repeated.
In such a state, when the anode side is connected to the above-mentioned conductor 6 and the cathode side to the conductor 7 from the generator attached to the engine, the water coming from the tube 12 is caused by the electrolytic solution, and the electrolytic tube 1 While gradually moving upward in the water tank 13 through the hollow part 3, the hydrogen that comes into contact with the inner wall of the electrolytic tube 1 and the outer circumferential wall of the electrode rod 2 is rapidly decomposed into hydrogen and oxygen. The gas flows back into the electrolyte tank 9 together with the electrolyte through the tube 8, where the electrolyte falls downward, and the gas body fills above and gradually becomes pressurized. On the other hand, the liquid in the electrolyte tank 9 gradually decreases due to the decrease in water accompanying the electrolysis work, and when the water level drops, the pipe 15
At the same time, the water level in the supply water tank 16 installed adjacent to the supply water tank 16 decreases, and as a result, the float valve device 17 is opened, and the water in the water tank 13 is pumped through the pipes 19 and 18 by the pump 20.
The electrolyte is replenished into the replenishment water tank 16 through the electrolyte tank 9, thereby keeping the liquid level in the electrolyte tank 9 constant at all times.

Reference numeral 21 denotes a bypass pipe in which the pump 20 is always operated during electrolysis in the electrolytic tube 1, and water is circulated only through this part when the float valve device 17 is closed.

The hydrogen and oxygen gas decomposed in this way are transferred to the pipe 22.
After passing through the alcohol liquid, it is sent through the pipe 25 again into the second booster 26, which is also filled with alcohol, and when the alcohol liquid passes twice, caustic soda and mist are removed. After completely removing impurities such as moisture, the gas is sent out from the pipe 28 as fuel gas for an internal combustion engine.

In the figure, reference numeral 14 indicates a water supply port of the aquarium, and 24 and 27 indicate alcohol supply ports of the booster, respectively.

In the present invention, as described above, by forming the electrolytic tube into a spiral shape, the electrolytic area that comes into contact with water and electrolytic solution is extremely increased, and because the inside of the electrolytic tube is constantly circulated, it is decomposed and the inner wall of the electrolytic tube and Since the generated gas bubbles adhering to the surface of the electrode rod are quickly released, the electrolytic action on the electrode surface is hardly inhibited and can be used effectively, resulting in a significant reduction in the amount of hydrogen and oxygen produced by electrolysis. can be increased.

Furthermore, since the long spiral electrolytic tube is installed inside the water tank for water replenishment, the inside of the tank can be used most effectively, and the heat generated in the electrolytic tube and electrode rod due to electrolysis is can be prevented.

Further, since the hydrogen and oxygen gases produced by the decomposition are passed through a booster filled with alcohol, all impurities contained therein are removed, resulting in various beneficial effects such as being able to obtain fuel gas of extremely high quality.
