The article investigates a method for improving the gas cleaning facility of the smelting shop № 1 using a change in the type of bag filters and the type of material used, as well as a method for cleaning the bags from accumulated contaminants. The article is devoted to evaluating the efficiency of operation and blowdown of pressure filters and filters with impulse regeneration. The principle of operation, feature and design of filters of pressure type with back blowing and filters with impulse regeneration have been studied. The technical characteristics of the used and proposed filters were analyzed. The article describes the existing problems with the existing gas treatment facilities of smelting shop № 1 and methods of their solution by upgrading these gas treatment facilities. Hydraulic tests have been carried out on the existing pressure filters with back blowing and proposed with impulse regeneration. The influence of untreated gas on abrasive wear of smoke exhausters and structural elements was evaluated. The influence of modernization of the gas treatment facilities of smelting shop № 1 on the environmental situation and reduction of emissions through structural improvements was evaluated. The use of dense non-woven materials as a raw material for the manufacture of bag filters instead of active woven and a denser configuration of bag filters in the gas cleaning will reduce the number of filters used, thereby reducing the placement area.
