As a new energy source, hydrogen is becoming increasingly important. The industrial-grade high-purity hydrogen production method includes water electrolysis, which produces hydrogen and oxygen, followed by a deoxygenation and drying process to achieve industrial-grade high-purity hydrogen production. However, the electrolysis cell needs to be equipped with positive and negative electrode components to realize the electrolysis process.

Detailed Implementation

[0022] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0023] Please see Figure 1-5 This application provides an industrial-grade high-purity hydrogen preparation device, including an electrolytic cell 10. A cover plate 20 is installed on the top of the electrolytic cell 10. Two insulating members 30 slide through the cover plate 20, and a positive electrode assembly 40 and a negative electrode assembly 50 are respectively inserted into the two insulating members 30. Each insulating member 30 is fitted with a locking block 60, and both locking blocks 60 are inserted into the cover plate 20. Specifically, the industrial-grade high-purity hydrogen preparation process includes water electrolysis, using deionized water. The cover plate 20 and the electrolytic cell 10 are... The connection is disassembled, and two insulating parts 30 slide through the cover plate 20. A positive electrode assembly 40 and a negative electrode assembly 50 are respectively inserted into the two insulating parts 30. The positive electrode assembly 40 and the negative electrode assembly 50 are connected to the power supply to electrolyze water in the electrolytic cell 10 to produce hydrogen and oxygen. The resulting gas is then purified, i.e., deoxygenated. The insulating parts 30 are fixed to the cover plate 20 by the locking block 60, which facilitates the disassembly and assembly of the insulating parts 30, and further facilitates the replacement of the positive electrode assembly 40 and the negative electrode assembly 50.

[0024] See Figure 3The insulating component 30 includes an insulating sleeve 310, which slides through the cover plate 20 and has a support plate 320 fixedly fitted on it. The support plate 320 is attached to the top of the cover plate 20. The locking block 60 is fitted on the insulating sleeve 310 and placed on the support plate 320. When set up, two through holes are opened on the cover plate 20, and the insulating sleeve 310 passes through the through holes. Furthermore, two rectangular frames 210 are fixedly installed on the top of the cover plate 20, and the two support plates 320 are respectively placed in the two rectangular frames 210. Positioning blocks 220 slide through the side walls of the two rectangular frames 210. The positioning blocks 220 are inserted into the side walls of the locking block 60. Specifically, the rectangular frames 210 can limit the support plate 320, and through holes are opened on the side walls of the rectangular frames 210. The positioning blocks 220 pass through the through holes and are inserted into the side walls of the locking block 60 to fix the locking block 60.

[0025] See Figure 3 Two elastic plates 230 are fixedly installed at one end of the positioning block 220. A slot 610 is provided on the side wall of the locking block 60. One end of the positioning block 220 is inserted into the slot 610, and the two elastic plates 230 are inserted into the slot 610 and pressed against the top and bottom of the slot 610 respectively. It should be noted that one end of the two elastic plates 230 is inclined so that the two elastic plates 230 can be pressed by the inner wall of the slot 610, thereby causing the elastic plates 230 to deform elastically, increasing the friction between the elastic plates 230 and the slot 610, and thus improving the stability of the positioning block 220.

[0026] See Figure 3-5The positive electrode assembly 40 includes a positive electrode connector 410, on which a positive electrode plate 420 is inserted. The positive electrode plate 420 passes through an insulating sleeve 310, and the positive electrode connector 410 is placed on the insulating sleeve 310. The negative electrode assembly 50 includes a negative electrode connector 510, on which a negative electrode plate 520 is inserted. The negative electrode plate 520 passes through an insulating sleeve 310, and the negative electrode connector 510 is placed on the insulating sleeve 310. The positive electrode connector 410 and the negative electrode connector 50 are connected together. Each of the head 510 has an assembly slot 70 at its bottom. The tops of the positive electrode plate 420 and the negative electrode plate 520 are respectively inserted into the two assembly slots 70. In specific installation, the two locking blocks 60 are frame-shaped and are respectively fitted onto the two insulating sleeves 310. Furthermore, the positive electrode connector 410 and the negative electrode connector 510 are insulated. Copper plates are fixedly installed on the tops of the two assembly slots 70. At the same time, the positive electrode connector 410 and the negative electrode connector 510 are... The top of head 510 is connected to the positive and negative terminals respectively. The positive and negative terminals are connected to two copper plates respectively. The tops of the positive plate 420 and the negative plate 520 are in contact with the two copper plates respectively. Furthermore, insulating blocks 710 slide through the side walls of the two assembly slots 70. Positioning slots are opened on the side walls of the positive plate 420 and the negative plate 520. One end of the insulating block 710 is inserted into the positioning slot. In specific settings, one end of the insulating block 710 is inserted into the positioning slot to position the positive plate 420 and the negative plate 520, thereby facilitating the assembly and disassembly of the positive plate 420 and the negative plate 520. It should be noted that through holes are also opened on the side walls of the two assembly slots 70. The insulating block 710 is inserted into the through holes. At the same time, the insulating block 710 is located inside the locking block 60. A groove is opened on the side wall of one end of the insulating block 710 to facilitate the removal of the insulating block 710 from the positioning slot.

[0027] See Figure 5 Both locking blocks 60 have L-shaped plates 620 fixedly installed on their tops. One end of each L-shaped plate 620 presses onto the positive terminal 410 and the negative terminal 510, respectively. When the two locking blocks 60 are respectively fitted onto the two insulating sleeves 310, the ends of the L-shaped plates 620 on both sides press onto the positive terminal 410 and the negative terminal 510 to fix the positive terminal 410 and the negative terminal 510.

[0028] See Figure 1 The top of the electrolytic cell 10 is connected to a liquid inlet pipe and a gas inlet pipe, and a drain pipe is connected to its side wall. Specifically, the liquid inlet pipe is connected to the existing liquid delivery device, while the gas inlet pipe is connected to the existing gas delivery device. An existing valve is installed on the drain pipe. In addition, an exhaust pipe is connected to the side wall of the electrolytic cell 10.

[0029] When this industrial-grade high-purity hydrogen preparation device is in operation: electrolytic water is introduced into the electrolytic cell 10, and the positive electrode assembly 40 and negative electrode assembly 50 are energized for electrolysis to produce hydrogen and oxygen. The hydrogen and oxygen enter the next process for deoxygenation treatment. When disassembling and assembling the positive electrode assembly 40 and negative electrode assembly 50, the positive electrode assembly 40 and negative electrode assembly 50 are de-energized. Then, the positioning block 220 is pulled out from the slot 610 on the side wall of the locking block 60, releasing the fixation of the locking block 60. The locking block 60 can then be pulled upwards, and the insulating block 710 can be removed to remove the positive electrode plate 420 or the negative electrode plate 520 for replacement. Finally, the positive electrode assembly 40 and the negative electrode assembly 50 are installed on the cover plate 20.

[0030] It should be noted that the specific models and specifications of the electrolytic cell 10, positive electrode connector 410, positive electrode plate 420, negative electrode connector 510 and negative electrode plate 520 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0031] The power supply and operating principle of the electrolytic cell 10, positive electrode connector 410, positive electrode plate 420, negative electrode connector 510 and negative electrode plate 520 are clear to those skilled in the art and will not be described in detail here.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
