Cupola Cupola cartridge filter cartridge filter uses a fully automated PLC controlled, sub-room cleaning, regular cleaning, with a small, combination in the form of flexible, interchangeable, long life, easy to operate, easy to replace cartridge , cleaning agencies reliable, excellent cleaning effect and so on. According to "casting dust technical regulations" requirement, emission concentration of the implementation of standards in the region 400 ~ 600m gm3 can install sprinklers in the chimney outlet; emission concentration of 200 ~ 400mgm3 implementation of standards in the region, in charge pretreated ( Waste casting sand, coke sieving, etc.) can be efficient cyclone; emission concentration of the implementation of standards in ≤200m gm region 3, should adopt the cartridge filter, electrostatic precipitator, in accordance with this provision, should be used in this treatment works baghouse or ESP. Cupola cartridge filter mainly by gravity settling chamber, high temperature gas shut-off valve, water-cooled multi-cyclone dust collector, water-cooled multi-tube cooler, thermocouple, sub-room cleaning cartridge filter, adjusting the damper, fan, silencer devices, pipes and chimneys and smoke dust desulfurization system components. After this removal equipment dust emissions ≤50 mg / Nm3 (20 ~ 50mg / Nm3), collection efficiency can reach 99.5%, blackness (Ringelmann blackness) is less than the level, SO2 reached the national emission standards, is soaring weapon of choice for environmental dust furnace equipment.
