[0002] At present, the hydrogen fuel cell industry is developing in the direction of industrialization, and the demand for hydrogen energy is also growing significantly. No matter what method is used to produce hydrogen, crude hydrogen is produced, which inevitably contains various impurities, which may have a significant impact on the application of hydrogen. The sulfides in it can cause serious damage to the fuel cell system, thereby affecting its service life and efficiency. In addition, a large amount of sulfides may also cause the catalyst in the hydrogen liquefaction system to fail, thereby affecting the performance of the system. Therefore, desulfurization of hydrogen is an indispensable and important step in the production of hydrogen.

[0003] In the process of producing hydrogen, a desulfurization tank is used for desulfurization. This desulfurization tank is mainly composed of a tank body, and the interior is filled with a desulfurizer specially used for desulfurization, so that hydrogen can achieve the desulfurization effect with the help of these desulfurizers. However, there are some problems in the actual application of such existing products, such as: when the existing desulfurization tank used for hydrogen production is used, the desulfurizer is not easy to replace after long-term use, and the problem of impure desulfurization is prone to occur.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Reference Figure 1-Figure 5 A desulfurization tank for hydrogen production comprises a square tank body 1 which is passed through from top to bottom, a desulfurization chamber 2 is slidably arranged in the tank body 1, a plurality of partitions 3 are arranged at intervals in the desulfurization chamber 2, a row of air holes 4 are provided on one side of each of the partitions 3, the air holes 4 on two adjacent partitions 3 are staggered left and right, and a desulfurizer 5 is filled between two adjacent partitions 3.

[0029] Specifically, the desulfurization bin 2 includes a U-shaped plate 201 and a baffle 202 slidably arranged at the opening of the U-shaped plate 201, grooves 6 are provided on both sides of the outer wall of the U-shaped plate 201, and a convex strip 7 matching the groove 6 is provided on the trough body 1, grooves 8 are provided on both sides of the baffle 202, and convex strips 9 matching the grooves 8 are provided on both sides of the inner wall of the U-shaped plate 201. Through the above-mentioned structure, the desulfurization bin 2 can be pulled out as a whole, and then the baffle 202 can be removed, and the desulfurizer 5 between the partitions 3 can be replaced, which is simple to operate and easy to use.

[0030] In this embodiment, an air outlet pipe 10 is disposed at the top of the tank body 1 , and an air inlet pipe 11 is disposed at the bottom of the tank body 1 . In addition, valves 15 are disposed on both the air inlet pipe 11 and the air outlet pipe 10 .

[0031] Please refer again Figure 2 A transition pipe 12 is arranged between the air intake pipe 11 and the tank body 1. Both ends of the transition pipe 12 are respectively connected to the air intake pipe 11 and the tank body 1, and a fan 13 is installed in the transition pipe 12. The fan 13 is located at one end of the transition pipe 12 close to the air intake pipe 11. The fan 13 can accelerate the air intake efficiency, thereby improving the desulfurization work efficiency.

[0032] It is worth mentioning that an observation window 14 is provided on one side of the transition pipe 12 , so that the working condition of the fan 13 can be observed, and it is also convenient to open the observation window 14 to inspect and repair the fan 13 .

[0033] In this embodiment, a handle 16 is hingedly provided on the U-shaped plate 201 to facilitate pulling out the desulfurization bin 2 as a whole.

[0034] In this embodiment, a sealing door 17 is hinged in front of the tank body 1, and a sealing rubber ring 18 is arranged on the end surface where the sealing door 17 is connected to the outer wall of the tank body 1. After the sealing door 17 is closed, the sealing of the tank body 1 is ensured.

[0035] In addition, a support leg 19 is provided at the bottom of the transition pipe 12 .

[0036] The working principle of the utility model is:

[0037] During use, the hydrogen to be desulfurized needs to be introduced into the transition pipe 12 through the intake pipe 11, and the use of the fan 13 can effectively improve the intake efficiency; as the hydrogen further enters the desulfurization chamber 2, please refer to Figure 2 Since a plurality of partitions 3 are arranged at intervals in the desulfurization bin 2, and the vents 4 on two adjacent partitions 3 are arranged alternately from left to right, the hydrogen is forced to pass through a row of vents and turn right, and then pass through another row of vents and turn left, and so on, the hydrogen will form a serpentine flow between the partitions 3, thereby increasing the contact time between the hydrogen and the desulfurizer 5 in a certain space, ensuring the desulfurization effect, and the desulfurized hydrogen is discharged through the outlet pipe 10 and collected centrally. The desulfurized hydrogen is discharged through the outlet pipe 10 and collected centrally.

[0038] After long-term use, the activity of the desulfurizer 5 will gradually decrease, and it needs to be replaced. The replacement process is relatively simple. First, open the sealed door 17, then pull the handle 16, and let the handle 16 drive the desulfurization bin 2 to move outward until the desulfurization bin 2 is completely out of the original position. Next, pull out the baffle 202, clean the used desulfurizer 5, and then put the new desulfurizer 5 back on the partition 3. Then reassemble the entire desulfurization bin 2 and put it into the tank body 1, and finally close the sealed door 17. The entire replacement process is simple and easy.
