| This article introduces the operation of the bag filter at the tail of the rotary kiln of Gezhouba Jiayu Cement Co., Ltd., the implementation plan of the transformation, and the operation effect after the transformation. By raising the height of the dust collector box, lengthening the filter bag, increasing the height of the settling chamber, improving the filtration area, reducing dust collection resistance, and minimizing the impact of dust laden air on the filter bag; After the renovation of the clean room, cover plate, insulation and anti-corrosion, spraying and flower hole, and filter bag cage, the overall dust collector is easy to maintain, the air leakage is reduced, and there is no water accumulation corrosion phenomenon. The transformed dust removal air volume can meet the post production (6200t/d) exhaust gas treatment capacity, with equipment operating resistance less than 1000Pa and dust emissions less than 10mg/m3, ensuring smooth ventilation of the kiln system, reducing system energy consumption, reducing carbon emissions, achieving ultra-low dust emissions, and meeting environmental and production requirements. |
