Исследована эффективность комплексной очистки газовых выбросов с установок термического обезвреживания отходов от пылевых частиц и сопутствующих кислых газовых примесей SO2, HCl и HF, а также летучих органических соединений (ЛОС) и диоксинов при температуре газовой смеси 300–400 °С с использованием керамических газофильтрующих элементов на основе алюмосиликатного волокна, модифицированных каталитической добавкой MgCr2O4. Показано, что результативность сорбционной очистки отходящих от печи газов от SO2, HCl и HF в период испытаний составила 79–90 % в зависимости от количества гидратированной извести, подаваемой в каталитический фильтр, что позволило предотвратить дезактивацию катализатора. Подтверждено, что выбранный температурный режим химической очистки (300–400 °С) позволил провести эффективную каталитическую очистку от ЛОС, СО и диоксинов в сочетании с эффектом хемосорбционного улавливания каталитических ядов и очисткой от пыли, тем самым не допустив ни деградации сорбента, ни отравления катализатора.

The efficiency of integrated gas emissions treatment in thermal waste treatment units from dust particles and fossil sour traces of SO2, HCl and HF, as well as volatile organic compounds (VOCs) and dioxins at 300–400 °C of the gas mixture with a ceramic gas filter with aluminosilicate fibers added with catalytic MgCr2O4. The efficiency of sorption purification of tail gases from SO2, HCl and HF during the test period was 79–90 %, which depended on the supply of slaked lime to the catalytic filter to prevent catalyst deactivation. Thermal mode of chemical refining (300–400 °C) provided effective catalytic purification from VOCs, CO, and dioxins in combination with the chemisorption recapture of catalytic poisons and dust, preventing neither sorbent degradation nor damage to the catalyst.
