Description

Technical Field

[0001] The utility model relates to a reverse venting gas recovery device for hydrogen production by pressure swing adsorption, belonging to the technical field of hydrogen purification. Background Art

[0002] The pressure swing adsorption process uses solid adsorbents such as octyl silica gel, activated carbon, molecular sieves, etc. installed in a vertical pressure vessel to selectively adsorb various impurities in the mixed gas. Due to the different boiling points of the components in the mixed gas, the raw gas passes through the adsorbent bed according to the properties of volatile components that are not easily adsorbed and non-volatile components that are easily adsorbed. The remaining components except hydrogen are selectively adsorbed by the adsorbent as impurities, while hydrogen with a low boiling point and the highest volatility is basically not adsorbed and leaves the adsorption bed with a purity of more than 98%, thereby achieving the purpose of separation from other impurities.

[0003] Chinese patent CN215352826U discloses a reverse venting recovery device for hydrogen production by pressure swing adsorption. The interior of the device can be observed through a transparent window. The frame and glass plate on the side of the tank body can allow light to enter the tank body, making the interior of the device brighter and convenient for people to observe through the transparent window. The two-layer glass plate can increase the strength of the light-transmitting part, avoid damage to the tank body, and facilitate the disassembly and assembly of the water tank. However, when the water tank is not in use, it is necessary to find another place to place it, which not only increases the waste of space, but also makes it inconvenient to take the water tank as needed, and it is time-consuming to take and put the water tank.
