Description

The present invention relates to an apparatus for electrolyzing water and generating a mixed gas of hydrogen and oxygen. More specifically, two opposing semi-cylindrical bodies are combined to form a cylindrical electrolytic cell. In this structure, the anode and cathode are connected to each half cylinder to supply power, and the two half-cylinder electrolytic cell cases themselves act as electrode plates, simplifying the structure, but with a large amount of hydrogen. The present invention relates to a large-capacity hydrogen / oxygen mixed gas generator capable of obtaining a mixed gas with oxygen.

The electrolysis theory that hydrogen and oxygen are generated when water is electrolyzed has been around 200 years ago. Various researches have been continued based on the theory, but in order to electrolyze water and generate gas, hydrogen and oxygen are separated and generated, and hydrogen and oxygen are generated in a mixed state. There is a way. The present invention relates to the latter apparatus for generating hydrogen and oxygen in a mixed state.

An apparatus for generating a mixed gas of hydrogen and oxygen has been researched and developed from about 35 years ago until now, and the core of this apparatus is an electrolytic cell structure for electrolyzing water. The structure of the electrolytic cell is roughly classified into a cylindrical electrolytic cell and a rectangular electrolytic cell.

The former cylindrical electrolytic cell has a structure in which a cathode power source is applied to a cylindrical case, and a nickel plate is mounted in the cylindrical case to apply an anode power source. In this structure, the cylindrical case functions as the cathode plate, and the nickel plate functions as the anode plate. However, the areas of the cathode plate and the anode plate are different, and there is a lot of unnecessary power consumption. Time driving is difficult. As another structure, there is a structure in which two nickel plates are mounted in a cylindrical case and a cathode power source and an anode power source are applied to the two nickel plates, respectively. In this structure, the two nickel plates function as a cathode plate and an anode plate, respectively. Since the areas of the cathode plate and the anode plate are the same, a mixed gas of hydrogen and oxygen is generated somewhat stably. it can. However, in any of the cylindrical electrolytic cells described above, it is difficult to maintain hermeticity in the process of mounting the nickel plate in the cylindrical case and sealing the part to be connected to the electric wire in a circular seal. The hermetic portion is weak to pressure and is not suitable for a large-capacity mixed gas generator of hydrogen and oxygen.

On the other hand, the latter square electrolytic cell has a structure in which a large number of electrode plates with a small area are arranged at regular intervals, an electrolytic chamber is provided with a rubber insulating member interposed therebetween, and an anode power source and a cathode power source are applied to both ends. There is. In such an electrolytic cell structure, if a long time elapses by using a large number of comb insulating members that insulate the electrode plate from each other, the insulating member melts due to heat and the electrolyte solution leaks out. As a result, a short circuit may occur, and it is not suitable for a mixed gas generator of a large volume of hydrogen and oxygen as well as operating for a long time. In order to eliminate the above structural problems, the left and right square cases are insulated and the anode power supply and the cathode power supply are applied respectively, and a plurality of electrode plates with a large area are laminated in the square case. There is a structure in which an insulating member is inserted between them. However, even in this structure, due to the characteristics of the square electrolytic cell, there is a weakness in pressure, and during operation, there is a risk that the electrolytic cell may be deformed by the pressure, and thereby the electrode plate may be disturbed and a short circuit may occur. .

In addition, in the cylindrical electrolytic cell described above and in the rectangular electrolytic cell, the electrolytic solution is spilled in the electrolytic cell and a part of the electrolytic solution comes out together with the mixed gas of hydrogen and oxygen during the electrolysis. There's a problem.

In addition, when the mixed gas of hydrogen and oxygen comes out through the water-sealed backfire preventer, the water-sealed reverse is caused by a phenomenon that the gas and the mixed gas of hydrogen and oxygen are lifted up. There is also a problem that water in the fire arrester comes out with a mixed gas of hydrogen and oxygen.

The present invention eliminates the problems of conventional hydrogen and oxygen mixed gas generators and can generate a large volume of hydrogen and oxygen mixed gas that can generate a large amount of hydrogen and oxygen mixed gas safely and efficiently. A device is provided.

The overall configuration of the present invention for solving the above-mentioned problems is that the left and right semi-cylindrical bodies are combined to form a cylindrical body, and an anode power source and a cathode power source are respectively applied to the left and right semi-cylindrical bodies. An electrolytic cell that electrolyzes water to generate and output a mixed gas of hydrogen and oxygen, a power supply unit that enables direct electrolysis of the electrolytic cell and electrolysis, and consumption by electrolysis An automatic water tank for supplying an appropriate amount of water to be supplied, a cooling means for preventing overheating of the electrolytic cell, a pressure adjusting unit for controlling the pressure of the output mixed gas of hydrogen and oxygen to be constant, and an internal Water-sealed backfire prevention that blocks the external flame from flowing back to the electrolytic cell by filling the water with water and sending the mixed gas of hydrogen and oxygen generated and output from the electrolytic cell through the water Instruments, voltage and current control and various instruments and And a control unit which comprehensively controls the components of the device such as a server, further to set the mixed gas of the output hydrogen and oxygen, and having a gas collection means to feed.

In addition, the basic structure of the electrolytic cell for electrolyzing water of the present invention to generate a mixed gas of hydrogen and oxygen has a coupling plate with a coupling hole formed at the edge, which itself is the electrode plate. The left and right electrolytic cell cases of the opposite semi-cylindrical bodies having the same radius and the left and right electrolytic cell cases of the opposite semi-cylindrical bodies having the same radius are intimately joined by interposing an insulating plate. An electrolysis chamber is formed, and the electrolyte is poured up to a certain height of the electrolysis chamber, and positive and negative DC power supplies are applied to the power input terminals provided on the left and right electrolytic cell cases of the semi-cylindrical body, respectively. A mixed gas of hydrogen and oxygen is generated and output.

The present invention is a structure in which two semi-cylindrical bodies facing each other are combined to form a cylindrical electrolytic cell, and an anode and a cathode are connected to each of these semi-cylindrical bodies to supply power. The electrolytic cell case itself serves as an electrode plate, so that it is possible to obtain a large amount of mixed gas of hydrogen and oxygen while simplifying the structure.

In particular, the left and right electrolytic cell cases having the same shape are used as an anode plate and a cathode plate, respectively, so that an electrolytic chamber having no electrode plate is formed inside the electrolytic cell, so that various problems due to the installation of the electrode plate are also eliminated. .

In addition, it is possible to construct a pressure-resistant device by designing the electrolytic cell into a cylindrical shape, and by adjusting the diameter and height of the cylindrical electrolytic cell in consideration of voltage and current, The generation amount of the mixed gas can be adjusted.

Furthermore, a huge amount of mixed gas of hydrogen and oxygen can be obtained safely and efficiently in a short time by connecting a large number of electrolytic cells in series and in parallel with electric wires.

In addition, in order to prevent the phenomenon that the electrolytic solution jumps up from the water surface inside the electrolytic cell and part of the electrolytic solution comes out with the mixed gas of hydrogen and oxygen during the electrolysis, it is adjacent to the gas discharge port inside the electrolytic cell. By installing the electrolytic solution outflow prevention plate provided on the inner surface, the electrolytic solution can be blocked from flowing into the gas outlet.

Furthermore, when the mixed gas of hydrogen and oxygen comes out through the water-sealed backfire preventer, the water in the water-sealed backfire preventer is caused by the discharge force of the mixed gas of hydrogen and oxygen. In order to prevent the phenomenon that occurs with the mixed gas of hydrogen and oxygen, water is discharged through the gas outlet by installing a water rise prevention plate and a water outflow prevention plate inside the water-sealed backfire preventer. The phenomenon can be prevented.

2. A water outflow prevention plate provided obliquely toward the gas discharge port above the water rise prevention plate in order to block water that has passed through the water rise prevention plate from flowing into the gas discharge port. A water-sealed backfire preventer for the large-capacity hydrogen / oxygen mixed gas generator described in 1.
