[0002] Biogas purification is the separation and removal of impurities and harmful gases in biogas by chemical methods to improve the purity and quality of biogas. It is mainly used in biogas projects to improve the purity and calorific value of biogas and make it a high-quality clean energy. Gas filter tanks are required for biogas purification. Gas filter tanks use filter media to adsorb or filter impurities and harmful substances in the gas, thereby purifying the gas. When the gas passes through the filter medium, the impurities and harmful substances are adsorbed or filtered out, and the clean gas is discharged through the outlet.

[0003] In the existing gas filter tank, when the biogas enters the filter tank through the air inlet pipe, the sealing effect of the connection of the air inlet pipe is poor, which easily leads to biogas leakage and threatens the safety of the staff. Therefore, it is necessary to propose a biogas purification absorption and filtering device. Utility Model Content
