Description

Technical Field

[0002] Gas impurity removal equipment is used to remove impurities, odors or harmful substances from gases. Common filtering functions include physical filtration, chemical adsorption and active gas treatment. This type of equipment is usually used in industrial production, laboratories, medical and other fields to obtain high-purity gases to meet specific application requirements.

[0003] However, the gas impurity removal equipment in the prior art usually uses an adsorbent filter as the main filter medium to filter the polluted air during use. However, the filter medium mainly relies on adsorption filtration to filter. When large particles of dust in the gas are inhaled, the filter medium will be blocked, which greatly reduces the adsorption effect and affects the filtration effect.
