Description

Technical Field

[0002] Bag filter is an efficient, economical and practical flue gas purification equipment, which is widely used in power, chemical, metallurgy, coal and other industries. The filtration of bag filter mainly uses the filtering effect of filter bag to block the dust particles in the flue gas on the surface of filter bag. Filter bag is generally made of high-performance polyester fiber or glass fiber, with high filtration efficiency and long-term performance. When the flue gas passes through the filter material, the dust particles are intercepted on the surface of the filter material to form a layer of filter cake. The dust above the filter bag is cleaned by pulse spraying and falls into the ash bin to restore the filtration performance. The existing bag filter is equipped with ash discharge valve and zipper machine at the bottom. The ash in the ash bin is transported to the ash tank through the ash discharge valve and zipper machine. The particulate matter is transported by forklift and short-cutting vehicle. The dust on site increases, the workload of dust prevention and cleaning personnel is increased, and the short-cutting cost is increased. In the process of conveying ash in the ash bin, the failure rate of ash discharge valve and zipper machine is high, the maintenance risk is high, and the maintenance cost is high, which indirectly increases the production cost.
