At the same time, the electrolyte carrying hydrogen will also enter the gas-liquid separation tank 2 with the help of the head of the circulating pump and the gas lift. Under the action of gravity, the hydrogen and the electrolyte are separated, and the electrolyte circulates back to the electrolytic cell. The electrolyte enters the electrolyte recovery device for purification and then passes into the electrolytic component 1. The hydrogen enters the cooling scrubber 4 and is cooled by the cooling process to reduce While lowering the gas temperature, the water content in the gas is reduced, and impurities in the hydrogen are removed. The hydrogen is then introduced into the deoxidizer 6, where the oxygen is removed by utilizing the principle that hydrogen and oxygen can generate water when heated under the action of a catalyst.

[0021] Furthermore, an adjusting screw 137 is vertically rotatably arranged between the positive plate 133 and the diaphragm 134, and the upper end of the adjusting screw 137 is fixedly arranged on the output shaft of the driving motor 136, and the driving motor 136 is fixedly assembled on the inner wall of the upper end of the carrying shell 131; A lifting sealing plate 138, a horizontal bolt is arranged on the adjusting screw 137, the lifting sealing plate 138 is sleeved on the outside of the positive plate 133, the diaphragm 134 and the negative plate 135, and a sliding sealing strip is arranged between the lifting sealing plate 138 and the inner wall of the carrying shell 131, the positive plate 133, the diaphragm 134 and the negative plate 135; As a preferred embodiment, by driving the motor 136 to rotate the adjusting screw 137 to raise and lower the lifting sealing plate 138, the contact area between the positive plate 133, the diaphragm 134 and the negative plate 135 and the electrolyte can be controlled, thereby adjusting the output efficiency of each combined electrolyzer 13, replenishing the loss of the combined electrolyzer 13 during operation, and maintaining the normal efficiency of the entire electrolysis assembly 1, thereby ensuring the hydrogen production efficiency.

[0022] Furthermore, two spring tubes 139 are provided at the upper end of the lifting sealing plate 138, the spring tube 139 adjacent to the positive plate 133 is connected to the oxygen exhaust pipe 14, and the spring tube 139 adjacent to the negative plate 135 is connected to the hydrogen exhaust pipe 15; As a preferred embodiment, the configuration of the spring tube 139 allows the actual length of the spring tube 139 to be adjusted according to the height of the lifting sealing plate 138, thereby ensuring the smooth discharge of oxygen and hydrogen and further ensuring the production efficiency of hydrogen.

[0023] Furthermore, the positive plates 133 of each combined electrolyzer 13 are connected together and connected to the positive pole of the power supply, and the negative plates 135 of each combined electrolyzer 13 are connected together and connected to the negative pole of the power supply.

[0024] Further, the deoxidizer 6 comprises: A fixed bracket 61 is fixedly assembled on the support frame 5, and a deoxidation shell 62 and an arc cylinder 65 are fixedly arranged on the fixed bracket 61. The deoxidation shell 62 is a semicircular ring-shaped member, and a catalyst block inlet bin 63 and a catalyst block outlet bin 64 are respectively arranged on both sides thereof, and a hydrogen outlet 67 and a hydrogen inlet 66 are respectively arranged on the outer side of the deoxidation shell 62 below the catalyst block inlet bin 63 and the catalyst block outlet bin 64; The catalyst block 68 is slidably disposed in the deoxidation shell 62, the catalyst block inlet chamber 63 and the catalyst block outlet chamber 64; The cylinder end of the arc cylinder 65 is fixedly mounted on the plane of the catalyst block discharge chamber 64 side of the deoxidation shell 62, and the piston end of the arc cylinder 65 is slidably arranged at one end of the catalyst block entry chamber 63 of the deoxidation shell 62; As a preferred embodiment, in actual work, the hydrogen after cooling and washing will enter the deoxidation shell 62 through the hydrogen inlet 66. The hydrogen and oxygen in the deoxidation shell 62 can be heated under the action of the catalyst to generate water, thereby removing oxygen. Finally, the hydrogen with oxygen removed is discharged from the deoxidizer 6 through the hydrogen outlet. In this process, after the catalyst combines with the reactant, a catalyst-reactant complex will be formed, resulting in the occupation of the active sites of the catalyst, thereby reducing its catalytic ability. In addition, factors such as high temperature and pollutants (such as impurities, water and other gases in the reactant) may also cause the catalyst to be deactivated or lost. Therefore, the closer the catalyst block 68 is to the hydrogen inlet 66, the more serious the consumption (the oxygen concentration at the hydrogen inlet 66 is relatively the highest). As time goes by, the catalyst block 68 will gradually lose its effectiveness. At this time, the arc cylinder 65 will start to push the catalyst block in the catalyst block entry bin 63 into the deoxidation shell 62, and the catalyst block 68 at the catalyst block discharge bin will be pushed into the catalyst block discharge bin 64 for treatment.

[0025] Furthermore, the catalyst block inlet bin 63 is provided with unused catalyst blocks 68 , and the catalyst block outlet bin 64 is used to place the catalyst blocks 68 that have lost their effectiveness.

[0026] When implemented specifically, the following steps are included: the electrolytic component 1 decomposes water through an external power supply, hydrogen is precipitated at the cathode, oxygen is precipitated at the anode, hydrogen enters the gas-liquid separation tank 2 through the hydrogen output end, and the electrolyte carrying hydrogen also enters the gas-liquid separation tank 2 with the help of the head of the circulation pump and the gas lift, hydrogen and electrolyte are separated under the action of gravity, the electrolyte circulates back to the electrolytic cell, the electrolyte enters the electrolyte recovery device for purification and then enters the electrolytic component 1, and the hydrogen enters the cooling scrubber 4 for supercooling process While lowering the gas temperature, the water content in the gas is reduced, and impurities in the hydrogen are removed. The hydrogen is then introduced into the deoxidizer 6 to remove oxygen based on the principle that hydrogen and oxygen can generate water when heated under the action of a catalyst. The deoxygenated hydrogen enters the dryer 7 for hydrogen drying and purification through a desiccant filtration process. The high-purity hydrogen obtained after separation, washing, deoxygenation and drying is compressed by a compressor 8 and stored in a hydrogen tank on a hydrogen storage rack 9. The hydrogen can be transported out after being filled in a hydrogenation column during the gas use process.
