Description

Anti-leakage and anti-internal gas explosion electrolyzer

1. Technical field

The utility model relates to an electrolytic cell, in particular to a leakage-proof and internal gas-explosion-proof electrolytic cell used in a hydrogen-oxygen fuel generator.

2. Background technology

In the prior art, the general hydrogen-oxygen generator is equipped with a circulation pump, whose function is to circulate the electrolyte in the electrolyzer and dissipate heat. However, due to the slow water flow and gas in the electrolytic cell, when the water pump of the cooling device pumps the electrolyte in the electrolytic cell for heat dissipation, it will reduce the liquid at the water outlet of the electrolytic cell and may cause electrolyte leakage. Tilting, so that the electrolytic current density of each electrolytic sheet is different, and then damage the electrolytic sheet with excessive current density, or cause scaling and failure due to high temperature.

The general water electrolysis electrolyzer is designed to include multiple electrode sheets and gaskets, and the electrolyte is between the electrode sheets, and the multiple electrode sheets are tightened by screws, which is easy to leak.

Another kind of electrolytic cell is not completely filled with electrolyte, generally there is a certain degree of hydrogen-oxygen mixed gas in the upper space of the electrolytic cell, which makes the unstable hydrogen-oxygen gas easy to explode in the cell, and when the gas explodes Finally, basically the electrolyzer will also leak and be difficult to maintain.

Another type of electrolytic cell is clogged because the internal space is not completely filled with water, allowing fouling to remain in the cell.

The outermost part of all electrolyzers is generally a metal sheet, so it is easy to generate leakage and cause danger.

3. The purpose of the invention

The purpose of this utility model is to provide a water electrolysis electrolyzer which is anti-leakage, anti-internal gas explosion and easy to maintain, so as to improve its safety and stability in the electrolysis industry and improve the overall efficiency of the hydrogen-oxygen generator.

This and other objects of the present utility model will be further manifested and illustrated through the following detailed description and illustration.

The anti-leakage and anti-internal gas explosion electrolytic cell of the utility model includes a first electrolytic cell and a second electrolytic cell, the first electrolytic cell and the second electrolytic cell are connected by a metal tube, and a three-way port is provided on the metal tube, one for The electrolyte enters, while the other port is connected with two pipes for the output of electrolyte and hydrogen-oxygen bubbles. The two ends of the electrolytic cell are equipped with electrode sheets, and there are electrolytic sheets and insulating gaskets inside the electrolytic cell. The sheets and insulating pads are placed at intervals, that is, only one piece of electrolytic sheets and gaskets are placed in the container alternately, which makes the electrolytic cell easy to clean and maintain.

Further, in the anti-leakage and anti-internal gas explosion electrolytic cell of the present invention, there are two circular holes on the electrode sheet and the electrolytic sheet, the circular hole at the lower position is for the electrolyte to enter, and the upper position The round hole is used to transmit electrolyte and hydrogen-oxygen bubbles. The position and size of the two round holes on the electrode sheet are the same or similar to those on the electrolytic sheet. The electrode sheet is thicker than the electrolytic sheet. The two ends of the electrolytic cell are provided with a plurality of screw holes for connecting the electrode sheet and the anti-corrosion container, and the screws do not pass through the electrode sheet in the electrolytic cell. There is a central axis in the electrolytic cell to fix the electrolytic sheet and the insulating rubber ring (gasket).

In the utility model, the holes for transmitting the electrolyte and the hydrogen-oxygen bubbles are shared, and the electrolytic sheet/electrolytic cell is at a higher position, so that the electrolytic cell is filled with the electrolyte, and the existing gas can only form a bubble state, which avoids Gas explosion inside the electrolyzer.

In the utility model, the electrolytic cell is composed of not less than two groups, and each group is composed of not less than two containers, which makes the whole electrolytic cell consist of not less than four insulating and anti-corrosion containers , easy to put in any position.

Because the container of the utility model is made of insulating materials, the container will not be charged due to the electrification of the electrolyte during use, and the use is relatively safe. In addition, during operation, the internal space of the electrolytic cell is full of electrolyte, and only bubbles are generated during the electrolysis process and taken away during the cycle, which prevents internal gas explosion and blockage caused by the accumulation of hydrogen and oxygen in the electrolytic cell, and greatly improves the electrolysis process. Groove security. And it can prevent leakage, prevent internal gas explosion and scale, easy to repair, easy to maintain and improve the performance of the hydrogen-oxygen generator, and can be used in different designs of hydrogen-oxygen mixed water electrolysis hydrogen generators.

5. Specific implementation

和绝缘垫片

交错放于电解槽容器1内，而在电解槽内不须任何螺丝固定，只须一条方向固定轴把它固定不会内电解液流过而转动。容器1两端为电极片2，两电极片2用多个螺丝9固定。电极片2上有两小孔，下圆形孔7用作入水，上圆形孔6用作输出电解液及氢氧混合气泡。这结构使整个电解槽易于清洗及保养维修及有防漏电的保护作用，使用安全。Refer to Figure 1-3, electrolytic sheet

and insulating spacers

They are staggered in the electrolytic cell container 1, and there is no need for any screws to fix them in the electrolytic cell, only one direction is needed to fix the shaft to fix it so that the inner electrolyte will not flow and rotate. The two ends of the container 1 are electrode sheets 2, and the two electrode sheets 2 are fixed by a plurality of screws 9. There are two small holes on the electrode sheet 2, the lower circular hole 7 is used for entering water, and the upper circular hole 6 is used for outputting electrolyte and hydrogen-oxygen mixed bubbles. This structure makes the whole electrolyzer easy to clean and maintain, and has the protective effect of preventing electric leakage, so it is safe to use.

The electrolyte is full in the electrolyzer container. Of course, air bubbles will be generated during the electrolysis process. According to the basic physical principle that the air bubbles rise upward, the liquid and air bubbles will be output from the water outlet and air bubble holes of the upper circular hole 6. Because there are only air bubbles inside, tempering and gas explosion cannot occur in terms of physical characteristics, which makes it safer and more reliable to use.

The lower circular hole 7 in Fig. 2 is used as entering water. And the electrolyzer of two groups is connected by a pipeline 4 and enters water by a tee 5. Since the entire container is also filled with liquid, when the circulation pump pumps the liquid out of the electrolytic cell, the same volume of liquid must be returned to the electrolytic cell. Therefore, the liquid level tilt and the current density are different when the general electrolytic cell is pumped out. Can solve scaling problems.
