Description

Technical Field

[0001] This utility model belongs to the technical field of sodium hypochlorite generators, specifically relating to sodium hypochlorite generators. Background Technology

[0002] With social development and increasing environmental protection requirements, the demand for efficient and safe disinfection products is growing. Sodium hypochlorite generators have emerged to meet this need. They produce sodium hypochlorite solution by electrolyzing saline solution for disinfection and sterilization. The operation is relatively simple and the cost is low.

[0003] Hydrogen is a flammable and explosive gas, which makes the collection process risky. If the equipment is not operated properly and air gets into it, it may cause a violent explosion when it comes into contact with a source of ignition, resulting in a serious safety accident. To collect hydrogen safely, complex and expensive explosion-proof equipment is required, which not only increases the cost of the equipment, but also increases the difficulty of maintenance and operating costs.

[0004] However, existing sodium hypochlorite generators have significant drawbacks. Hydrogen gas is produced during electrolysis within their reaction tanks, an unavoidable byproduct. Separating and collecting the hydrogen gas from the sodium hypochlorite presents numerous challenges.

[0005] Therefore, in response to the problems of existing sodium hypochlorite generators, such as the inconvenience of separating and collecting hydrogen gas and sodium hypochlorite generated in the reaction tank, and the difficulty in collecting flammable and explosive hydrogen gas, a sodium hypochlorite generator can be designed. Utility Model Content

[0006] To overcome the problems of existing sodium hypochlorite generators, such as the inconvenience of separating and collecting hydrogen gas generated in the reaction tank from sodium hypochlorite, and the difficulty in collecting flammable and explosive hydrogen gas.

[0007] The technical solution of this utility model is as follows: a sodium hypochlorite generator, including an electrolytic cell assembly, a mixing tank assembly, and a hydrogen-oxygen fuel cell stack assembly; the mixing tank assembly is arranged in front of the electrolytic cell assembly; the hydrogen-oxygen fuel cell stack assembly is arranged between the electrolytic cell assembly and the mixing tank assembly; the electrolytic cell assembly includes an electrolytic cell, a reaction tube, an electrolytic electrode, a hydrogen output pipe, a sodium hypochlorite output pipe, and a transformer; the mixing tank assembly includes a mixing tank and a pump; the hydrogen-oxygen fuel cell stack assembly includes a hydrogen-oxygen fuel cell stack, a hydrogen input tank, an oxygen input tank, a drain pipe, and an output cable.

[0008] Preferably, the sodium hypochlorite solution and hydrogen electrolyzed in the electrolysis cell are separated by a mixing tank assembly, and then the separated hydrogen is directly introduced into the hydrogen-oxygen fuel cell stack assembly to generate electricity. The electricity generated by the fuel cell is input to a transformer for voltage boosting and then fed into the electrolysis electrodes for reuse. This improves energy efficiency and eliminates the need to collect flammable and explosive hydrogen. This solves the problem of existing sodium hypochlorite generators, where the hydrogen generated in the reaction tank is inconvenient to separate and collect from the sodium hypochlorite, and the flammable and explosive nature of the hydrogen makes collection difficult.

[0009] Preferably, the electrolytic cell is equipped with reaction tubes connected in series; electrolytic electrodes are arranged crosswise above the reaction tubes, and the electrode ends of the electrolytic electrodes are located inside the reaction tubes.

[0010] Preferably, a sodium hypochlorite output pipe and a transformer are respectively installed on both sides of the electrolytic cell, and the transformer is electrically connected to the electrolytic electrode, and the reaction tube is connected to the sodium hypochlorite output pipe.

[0011] Preferably, a hydrogen output pipe is provided above the sodium hypochlorite output pipe, and the hydrogen output pipe is connected to the reaction pipe.

[0012] Preferably, a pump is installed on one side of the mixing tank, and the input end of the pump is connected to the output end of the mixing tank via a pipeline. Furthermore, a hydrogen output pipe is connected to the upper end of the mixing tank via a pipeline. The mixture of sodium hypochlorite and hydrogen inside the hydrogen output pipe is introduced into the interior of the mixing tank.

[0013] Preferably, a hydrogen-oxygen fuel cell stack is provided between the mixing tank and the electrolysis cell; an oxygen input tank and a drain pipe are respectively provided on both sides of the hydrogen-oxygen fuel cell stack; and a hydrogen input tank is provided above the oxygen input tank.

[0016] The beneficial effects of this utility model are:

[0017] 1. Existing sodium hypochlorite generators suffer from the problem of inconvenient separation and collection of hydrogen generated in the reaction tank from sodium hypochlorite, and the flammability and explosiveness of hydrogen make collection difficult. A new method addresses this issue by using a mixing tank assembly to separate the sodium hypochlorite solution and hydrogen from the electrolyzed sodium hypochlorite solution in the electrolysis tank assembly. This separated hydrogen is then directly fed into a hydrogen-oxygen fuel cell stack assembly to generate electricity. The electricity generated by the fuel cell is then boosted by a transformer and finally fed into the electrolysis electrodes for reuse, improving energy efficiency and eliminating the need to collect flammable and explosive hydrogen. This method solves the problems of existing sodium hypochlorite generators, which suffer from the inconvenience of separating and collecting hydrogen from sodium hypochlorite in the reaction tank, and the difficulty of collecting the flammable and explosive hydrogen.

[0018] 2. By setting up the mixing tank assembly, the sodium hypochlorite solution and hydrogen gas input through the hydrogen output pipe are separated by gravity. The upper layer of hydrogen gas is fed into the hydrogen-oxygen fuel cell stack for power generation along the hydrogen input tank, while the lower layer of sodium hypochlorite is discharged and collected by the pump. Reducing the sodium hypochlorite concentration in the reaction tube is beneficial to the electrolysis reaction. Attached Figure Description

The reaction tubes 102 and the sodium hypochlorite output pipe 105 are connected in series. A hydrogen output pipe 104 is provided above the sodium hypochlorite output pipe 105, and the hydrogen output pipe 104 is connected in series with the reaction tubes 102. A pump 202 is provided on one side of the mixing tank 201, and the input end of the pump 202 is connected to the mixing tank 201. The output pipeline is connected, and the hydrogen output pipe 104 is connected to the upper pipeline of the mixing tank 201. The mixture of sodium hypochlorite and hydrogen inside the hydrogen output pipe 104 is introduced into the mixing tank 201.

This improves energy utilization efficiency and eliminates the need to collect flammable and explosive hydrogen. This avoids the problems of existing sodium hypochlorite generators, where the hydrogen generated in the reaction tank is inconvenient to separate and collect from the sodium hypochlorite, and the flammable and explosive nature of the hydrogen makes collection difficult.
