Abstract

The paper considers an adsorption gas filter with a short diffuser for air purification from hydrocarbon vapors. Experimental researches of various options for reducing the flow unevenness in front of the filter element in the flow part of the gas filter were carried out, and their significant shortcomings were revealed. The profiling of the adsorption layer in the flow part of the gas filter on the basis of the flow velocity field profile is proposed. An increase the efficiency of the gas filter with a profiled adsorption cassette from the point of view of the criteria of gasdynamic efficiency was revealed, and a decrease in the volume of adsorbent filling by 17.6% was achieved while maintaining the same performance.The paper considers an adsorption gas filter with a short diffuser for air purification from hydrocarbon vapors.
