Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic cell tank leakage detection, in particular to an ion membrane electrolytic cell tank leakage detection device. Background Art

[0002] An ion membrane electrolyzer is an electrolysis device, usually used for water electrolysis to produce hydrogen or oxygen. The anode and cathode are separated by an ion membrane inside the electrolyzer. The ion membrane has the ability to selectively permeate ions, allowing specific ions to pass through while preventing other ions from passing through. During the electrolysis process, current passes through the electrolyte solution, decomposing water into hydrogen and oxygen, and forming ions between the anode and cathode. The gas pipeline for collecting hydrogen and oxygen is an important channel to ensure the entire electrolysis process, and it is also very important to ensure the normal operation of the channel and to seal it without leakage.

[0003] Existing leak detection of gas pipelines of electrolyzers generally needs to rely on workers to operate, with low detection efficiency and inability to conduct comprehensive leak inspections in batches. For example, a worker points the test instrument at one side of the pipeline and then moves it close to the next side. The test readings of multiple sides are checked to see if the readings are consistent. If they are consistent, it indicates that the gas pressures in the pipelines are the same. If the readings are different, it means that there is one or more gas leaks and further inspections are required. The efficiency is low and batch inspections are not possible.

[0004] Therefore, it is necessary to invent a leakage detection device for an ion membrane electrolysis unit cell to solve the above problems. Utility Model Content

[0005] The utility model aims to provide an ion membrane electrolysis unit cell leak detection device to solve the problem that the electrolysis unit cells in the technology cannot be used to detect the leakage of gas pipelines in batches.

[0007] Preferably, the leak detection mechanism further comprises an insertion rod, a micro air pump arranged in the insertion rod, and a soap liquid bucket connected to the output end of the micro air pump, and the conical insertion rod is inserted into the rubber valve.

[0008] Preferably, the leak detection mechanism includes a fixed rod, a block, a rotating plate, a connecting rod and a motor, the fixed rod is fixedly connected to the electrolysis unit tank body, the block is fixedly connected to one side of the rotating plate, the other side of the rotating plate is rotatably connected to the connecting rod, and the connecting rod is sleeved on the rotating shaft of the motor.

[0010] Preferably, the block can extend into the swing rod, and a U-shaped groove is provided at the bottom end of the swing rod, and the width of the U-shaped groove coincides with the diameter of the block.

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model provides Figure 1-3 The leak detection device of an ion membrane electrolysis unit cell shown in the figure comprises an electrolysis unit cell body 1, oxygen and hydrogen flow pipes 2 and a leak detection mechanism. The oxygen and hydrogen flow pipes 2 are arranged on the electrolysis unit cell body 1. The oxygen and hydrogen flow pipes 2 are filled with oxygen and hydrogen. Rubber valves 3 are arranged at the ends of the oxygen and hydrogen flow pipes 2. The leak detection mechanism is inserted into the rubber valve 3 to check whether there is a leak. The leak detection mechanism comprises a swing rod 5 and a silicone brush 8. As the swing rod 5 and the silicone brush 8 swing, soap liquid is coated on the surface of the oxygen and hydrogen flow pipes 2.

[0024] If there is a leak in the surface gas pipelines of the multiple oxygen and hydrogen flow pipelines 2 on the entire electrolytic unit tank body 1, a layer of soap liquid will be smeared on the surface by the silicone brush 8 when passing through the surface. The leakage phenomenon will produce bubbles at the leakage point, thereby ensuring that the electrolysis process of the entire electrolytic unit tank body 1 does not leak.

[0025] The leak detection mechanism also includes an insertion rod 4, a micro air pump 6 arranged in the insertion rod 4, and a soap liquid bucket 7 connected to the output end of the micro air pump 6. The conical insertion rod 4 is inserted into the rubber valve 3. The leak detection mechanism includes a fixed rod 9, a clamping block 10, a rotating plate 11, a connecting rod 12 and a motor 13. The fixed rod 9 is fixedly connected to the electrolytic unit tank body 1, the clamping block 10 is fixedly connected to one side of the rotating plate 11, and the other side of the rotating plate 11 is rotatably connected to the connecting rod 12, and the connecting rod 12 is sleeved on the rotating shaft of the motor 13.

[0026] The leak detection mechanism is inserted into the rubber valve 3 at the end of the oxygen and hydrogen circulation pipeline 2, so that part of the gas in the oxygen and hydrogen circulation pipeline 2 is transported to the micro air pump 6, and the soap liquid in the soap liquid bucket 7 is pushed to the position of multiple silicone brushes 8. The silicone brushes 8 swing and contact with the oxygen and hydrogen circulation pipeline 2, and the soap liquid is applied to the surface of the oxygen and hydrogen circulation pipeline 2.

[0027] An axis is provided at the center of the rotating plate 11, and the axis is rotatably connected to the bottom end of the fixed rod 9. The rotating plate 11 swings left and right with the axis as the center of the circle. The block 10 can be inserted into the swing rod 5. A U-shaped groove is provided at the bottom end of the swing rod 5. The width of the U-shaped groove coincides with the diameter of the block 10. The swing rod 5 swings left and right with the insertion rod 4 as the center of the circle. The upper half of the swing rod 5 is hollow, and the hollow range spreads to the top of each silicone brush 8. The bottom end of the silicone brush 8 is a soft brush.

[0028] Each time the rotating plate 11 swings, the block 10 is inserted into the U-shaped groove, and the swing rod 5 can be swung. Each time the swing rod 5 swings, the surface of the oxygen and hydrogen flow pipes 2 can be coated with soap liquid.

[0029] Working principle of this utility model:

[0030] Refer to the instruction manual Figure 1-3 When using the utility model, firstly, the multiple oxygen and hydrogen flow pipes 2 on the electrolysis unit tank body 1 are used to collect the oxygen or hydrogen after electrolysis, and multiple collection channels are formed through the multiple oxygen and hydrogen flow pipes 2. The gas flow of multiple channels can ensure the smooth operation of the entire electrolysis process;

[0031] Refer to the instruction manual Figure 3-5 When using the utility model, soapy water is evenly applied to the surfaces of the multiple oxygen and hydrogen flow pipes 2 (if there is a gas leak, obvious bubbles will appear) to detect whether there is a leak in the multiple oxygen and hydrogen flow pipes 2;

[0032] The motor 13 is started to drive the linkage between the connecting rod 12 and the rotating plate 11. The rotating plate 11 swings with the bottom end of the fixed rod 9 as the center, so that half of the swing distance of the block 10 is inserted into the U-shaped groove at the bottom of the swing rod 5. When inserted into the U-shaped groove, the swing rod 5 is driven to swing with the insertion rod 4 as the center, and the silicone brush 8 is driven to continuously contact the surfaces of multiple oxygen and hydrogen flow pipes 2 (when the insertion rod 4 is extended into the rubber valve 3, part of the oxygen or hydrogen will be filled into the micro air pump 6 and stored in the micro air pump 6 as energy to push the soap liquid in the soap liquid barrel 7 out, and the soap liquid in 7 is pushed to the multiple silicone brushes 8).
