[Problems to be Solved by the Invention] Conventional oxygen, hydrogen, and mixed gas generators have problems with the structure and fixing method of the electrode tubes, and the lifespan of the device is relatively short and the gas generation efficiency quickly decreases. It had some drawbacks.

[0004] The present invention has been made in order to improve such problems, and it is possible to increase the gas generation efficiency from the electrolytic cell to generate a large amount of gas, and also to reduce the amount of electrolyte mixed in the generated gas. The purpose of the present invention is to provide an oxygen, hydrogen, and mixed gas generator that filters and removes liquid components and moisture and supplies high-quality gas.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the oxygen, hydrogen and mixed gas generator of the present invention has a cylindrical shape with nickel plating on the surface and through holes 3a formed at the upper and lower ends. Electrode tubes 3 made of mild steel plates are arranged in multiple layers at regular intervals around the outer periphery of the anode rod 2, and their upper and lower ends are fixed with synthetic resin fixing plates 4 and 5 to constitute an electrode assembly A. A is installed in electrolytic cells 1 and 1a, and oxygen and hydrogen gas are generated by electrolysis, and the generated gas is passed through a gas washer 10 and a filter 11 to filter and remove electrolyte components and moisture in the gas. After that, it is supplied to the supply section.

[0006]

[Operation] In the electrolytic cell, oxygen gas is generated near the anode rod and hydrogen gas is generated near the electrode tube. The generated oxygen, hydrogen, and mixed gas are sent to a gas washer, passed through a filter and a water seal filtration safety device to remove impurities, and then passed through a regulator and flashback preventer before being discharged from the gas outlet.

ITCH) 20 is connected to prevent overcurrent, and the transformer (P
OWER TRANSFORMER) 21 to a predetermined voltage, and a rectifier (DC RECTIFIER) 22.
This DC current is stabilized by a current controller operated by a delivery resistor and a gas generator load, and then supplied to the device.

As shown in FIG. 3, the gas generating section has a structure in which an electrode assembly A is inserted into an electrolytic cell 1, 1a. As shown in FIG. 4, an anode rod 2 is placed at the center, and around its outer periphery, cylindrical large and small electrode tubes 3, which are plated with nickel (Ni) on the surface of a mild steel plate by an electroless method, are arranged in multiple layers. The upper and lower ends of each electrode tube 3 are fixed to synthetic resin fixing plates 4 and 5 fixed to both ends of the electrode tube 2, thereby forming an electrode assembly A. In addition, through-hole portions 3a are formed at the peripheries of the upper and lower ends of each electrode tube 3. This electrode assembly A is inserted into the electrolytic cells 1 and 1a to constitute a gas generator.

The gas generator of the present invention is based on a bipolar (BIPOLAR) vertical rotating cathode type in an electrolyzer, and a power supply is connected between the central (+) pole and (-) cathode cell. A large number of electrode tubes 3 that are indirectly charged are arranged at regular intervals, and the (+) charged parts are filled with oxygen gas.
Hydrogen gas is generated in the (-) charged part.

The structure of the electrode is such that six cylindrical electrode tubes 3 of different sizes are inserted and arranged around one (+) pole rod 2, and the electrode tube 3 itself changes to the radius of the cylindrical part. It has the advantage that the purpose can be fully achieved even if only the length is adjusted without (increase).

[0012] Regarding the construction of the electrode assembly A, (+
) The pole rod 2 and the pole tube 3 are fixed by the upper and lower synthetic resin fixing plates 4 and 5 so as to form a multiplex structure at regular intervals, and in particular the fixing bolts of the upper synthetic resin fixing plate are made of nylon #6 or the like. As it is molded inside, it compensates for the disadvantage that the (+) pole rod 2 is destroyed by the overvoltage caused by the generation of charged current during electrolysis.

An insulating pad (PAD) is provided on the outer periphery of the lower end current-carrying rod 2a to provide electrical insulation and to prevent water leakage.

An inlet 1' and an outlet 1'' are provided at the upper part of the electrolytic cells 1, 1a, and a pressure switch 8 is fixed to the inlet 1'. A water level adjustment sensor 6 for adjusting the water level, a temperature measuring switch for maintaining the temperature at a predetermined temperature, and a cooling fan 9 are also attached.

By configuring the electrode tube 3 as a multi-electrode tube 3 with a cylindrical shape, gas generation efficiency for a constant electric power is maximized. In addition, through holes 3a are provided at the upper and lower ends of the electrode tube 3.
By forming gas bubbles (VAPOU) generated on the surface of the electrode tube 3 by the pressure inside the gas generator in the electrolyte,
R) is made to separate more quickly from the surface of the electrode tube 3, thereby further increasing gas generation efficiency. Furthermore, by applying nickel (Ni) plating to the surface of the electrode tube (CELL) 3, which is the core of the gas generator, oxidation of the electrode surface is prevented and overvoltage (OVER VOL) between the electrode and the electrolyte is prevented.

[0017] The electrolytic cells 1 and 1a can be installed in series by separating them into an insulating layer and another insulating layer, and in this case, a larger amount of gas can be produced.

The gas processing section sends the generated hydrogen, oxygen and mixed gases from the electrolytic cells 1 and 1a through hoses to a gas washer 10, passes through a filter 11 and a water ring type filtration safety device 12, and removes impurities.

The gas generated from the electrolytic cells 1 and 1a containing a mixture of electrolyte components and moisture is first cleaned in a gas washer 10, and the electrolyte passes through a recovery valve and an electrolyte recovery hose 17. It is then resupplied to the lower part of the electrolytic cells 1 and 1a. On the other hand, oxygen, hydrogen, and mixed gas pass through a multi-stage filter 11, pass through a flashback preventer 14, and are discharged to a gas outlet 15, producing a large amount of high-quality gas. , can be supplied.

Effects of the Invention The oxygen, hydrogen, and mixed gas generator of the present invention can maximize gas generation efficiency by adopting a cylindrical multipolar tube, and also has a through hole formed in the polar tube. By doing so, the gas bubbles can be separated from the electrode tube surface more quickly, and the gas generation efficiency can be further increased. Furthermore, by applying nickel plating to the surface of the electrode tube, oxidation of the electrode surface can be prevented and overvoltage can be reduced to a minimum.
