Experimental research of the efficiency of gas filters with a short diffuser
The article considers gas adsorption and catalytic filters with a short diffuser for air cleaning from aerosol and gas impurities. In the course of the work, comparative experimental studies of a gas filter with a flat partition and a short diffuser with uneven concentric guides in terms of the gasdynamic efficiency criteria were carried out. A positive effect was revealed when replacing the flat partition with a short diffuser with uneven concentric guides, which presupposes reducing the aerodynamic resistance and obtaining a more uniform velocity field in the flow part of the filter. It has been established that the use of a short diffuser with uneven concentric guides allows reducing the thickness of the layer of adsorption and catalytic materials in filters by up to 30% compared to the basic structure with a flat partition.
