[0002] Zeolite is a silicate mineral with a variety of pore sizes and can be used as a molecular sieve agent. The zeolite fixed bed is divided into chambers and requires valve switching of a single chamber to complete the conversion of adsorption and desorption.

Especially in the design of the square fixed bed, there are relatively high concentrations of residual exhaust gas in the four corners. The concentration of the desorbed exhaust gas will gradually increase with the increase of the fixed bed temperature. The exhaust gas concentration is unstable. Once the desorption concentration is high, there is a risk of explosion. Summary of the invention
