Аннотация: The efficiency of the scheme of "dry" cleaning of gas furnaces by nephelines dur- ing the use of electrostatic precipitators at RUSAL Achinsk is insufficient to ensure the max- imum permissible concentration limit for suspended particles. In this regard, the introduction of an additional stage of "wet" post-treatment of gases is prПоказать полностьюoposed. A multi-vortex hy- drotreater was used to carry out pilot industrial tests in which gas purification takes place in a dispersed water-air layer formed as the gases pass from below upwards through the dispersing grid. As an absorbing irrigating solution, it has been proposed to use sub-slime water. An as- sessment was made of the efficiency of dust removal of gases by hydrofilters. The operation of the hydrofilters has shown the following results: the efficiency of the hydrofilters during the pilot tests at the rate of the cleaning solution (sub-slime water) 0.3-0.45 dm3 / Nm3 of the cleaned gas in the pilot plant was (95 %), for industrial water filters - on the average 85 %, the introduction of the hydrofilter allows to reduce gross emissions of polluting substances by 8700 tons / year and to reduce environmental payments by 270.6 million rubles per year
