Abstract
1. Способ очистки отходящих газов рудно-термической печи, заключающийся в том, что отводят отходящие при плавке газы через газоход, охлаждают их до 200°С в газоходах с помощью системы испарительного охлаждения, проводят двухстадийную - грубую и тонкую - очистку газов от вредных примесей и пыли, причем очистку от примесей проводят на первой ступени охлаждения путем сжигания реакционных газов, а очистку от пыли выполняют сначала в циклонах с возвратом уловленной пыли на процесс плавки, затем в металлотканевых фильтрах с регенерацией фильтра сжатым воздухом, который предварительно сушат, а пыль, полученную после очистки на фильтре, подвергают дальнейшей переработке, отличающийся тем, что отвод газов осуществляют через два газохода, охлаждение газов производят путем подсоса атмосферного воздуха, очистку от пыли проводят в циклонах, где улавливают частицы пыли крупностью более 0,1 мм, проводят искрогашение, перемешивают газы с охлаждающим воздухом, тонкую очистку выполняют последовательно в нескольких автономных секциях рукавного фильтра, при этом в ходе технологического процесса контролируют температуру и вибрацию отдельных узлов, потребляемую электродвигателем мощность, измеряют давление и температуру в газоходах перед фильтрами и в зависимости от их величин регулируют производительность дымососа, управляют регенерацией фильтров и работой электродвигателя. ! 2. Установка очистки отходящих газов рудно-термической печи, содержащая печь со сводом, на котором размещен газоход, двухступенчатую - грубую и тонкую - систему очистки, включающую систему охлаждения газов, циклоны и металлотканевые фильтры с устройс�1. The method of purification of exhaust gases from an ore-thermal furnace, which consists in removing exhaust gases during smelting through a gas duct, cooling them to 200 ° C in the ducts using an evaporative cooling system, and conducting a two-stage - coarse and fine - purification of gases from harmful impurities and dust, moreover, purification from impurities is carried out in the first stage of cooling by burning reaction gases, and dust is cleaned first in cyclones with return of captured dust to the smelting process, then in metal fabric filters with filter regeneration with air, which is pre-dried, and the dust obtained after cleaning on the filter is subjected to further processing, characterized in that the gases are removed through two ducts, the gases are cooled by suction of atmospheric air, dust is cleaned in cyclones where dust particles are collected fineness of more than 0.1 mm, spark suppression is carried out, gases are mixed with cooling air, thin cleaning is carried out sequentially in several autonomous sections of the bag filter, while during the process CCA control the temperature and vibration of individual nodes, the power consumed by the electric motor, measure the pressure and temperature in the gas ducts in front of the filters and, depending on their values, regulate the performance of the exhaust fan, control the regeneration of the filters and the operation of the electric motor. ! 2. Installation for cleaning the exhaust gases of an ore-thermal furnace, containing a furnace with a vault on which the gas duct is located, a two-stage - coarse and thin - cleaning system, including a gas cooling system, cyclones and metal fabric filters with a device
