[0003] This type of adsorption tank increases the length of the adsorption section, but also reduces the size of the gas inlet of the adsorption section, resulting in slow gas entry into the adsorption section and low adsorption efficiency. At the same time, larger impurities in the gas will fall during the adsorption process and easily block the gas inlet, further reducing the adsorption efficiency. Summary of the invention

[0004] Aiming at the shortcomings of the existing adsorption tank that the gas enters the adsorption section slowly and is easy to clog the air inlet, resulting in low adsorption efficiency, the utility model provides a gas adsorption tank, the gas enters the adsorption section faster, is not easy to clog, and has high adsorption efficiency.

[0005] A gas adsorption tank comprises a tank body, wherein an upper grid, an upper ceramic ball layer, an adsorption section, a lower ceramic ball layer and a lower grid are arranged in the tank body, the adsorption section is filled with an adsorbent, the top of the tank body is connected to an air outlet pipe, and the bottom of the tank body is connected to an air inlet pipe, characterized in that a first partition plate and a second partition plate are longitudinally arranged in the adsorption section, the first partition plate and the second partition plate are wavy, both side surfaces of the first partition plate and the second partition plate are connected to an adsorption layer, and the first partition plate and the second partition plate divide the adsorption section into three cavities.

[0006] It is further characterized by:

[0011] In the above structure of the utility model, the arrangement of the first and second wavy partitions makes it possible to increase the adsorption length without reducing the size of the entrance of the gas into the adsorption section, thereby enabling the gas to quickly enter the adsorption section and improving the adsorption efficiency. The arrangement of the guide plate allows the gas to enter the three cavities evenly, preventing most of the gas from entering the same cavity, thereby ensuring the stability of the adsorption efficiency. When the gas enters the air intake pipe, larger impurities are first filtered by the filter net, and after the impurities fall, they slide into the collection box along the inclined air intake pipe, effectively preventing the air intake pipe from being blocked, further improving the adsorption efficiency.

[0014] See Figure 1 A gas adsorption tank includes a tank body 1, an upper grid 2, an upper ceramic ball layer 3, an adsorption section 4, a lower ceramic ball layer 5 and a lower grid 6 are arranged in the tank body 1, the adsorption section 4 is filled with an adsorbent, the top of the tank body 1 is connected to an air outlet pipe 7, and the bottom of the tank body 1 is connected to an air inlet pipe 13. A first partition 8 and a second partition 9 are arranged in the longitudinal direction in the adsorption section, the first partition 8 and the second partition 9 are wavy, and the surfaces of both sides of the first partition 8 and the second partition 9 are connected to an adsorption layer 10. The first partition 8 and the second partition 9 divide the adsorption section into three cavities, which are cavities 41, 42, and 43 respectively. A guide plate 12 is arranged under the lower grid 6 in the tank body 1. The gas can enter the three cavities 41, 42, and 43 at the same time and evenly, ensuring the stability of the adsorption efficiency. After entering the adsorption section 4, the gas rises along the first partition 8 and the second partition 9, which increases the adsorption distance without reducing the size of the entrance of the gas into the adsorption section 4.

When the collection box 15 is full, it can be removed and cleaned, which effectively prevents the air intake pipe from being blocked.

[0016] The tank body 1 is provided with a hand hole 16 below the lower grille, which can be opened to clean the guide plate 12 and the bottom of the tank body 1 to prevent clogging caused by residual impurities.

[0017] A temperature sensor 11 is provided in the middle section of the air inlet pipe 13 and the tank body 1, which will sound an alarm when the temperature is too high, so as to avoid the failure caused by the over-high temperature during the adsorption of high-temperature gas affecting the working efficiency of the adsorption tank.
