Bag Filter
By using a high-voltage direct current electric field, the dust particles in the dusty gas are charged, and under the action of the electric field force, they deposit on the surface of the settling electrode. Then, under the action of the vibration force, the flaky dust falls into the ash hopper, which purifies the flue gas passing through the electrostatic precipitator and meets the environmental protection emission standards. It is an ideal equipment for purifying industrial waste gases such as thermal power generation, metallurgy, papermaking, building materials, and non-ferrous metals.

By using a high-voltage direct current electric field, the dust particles in the dusty gas are charged, and under the action of the electric field force, they deposit on the surface of the settling electrode. Then, under the action of the vibration force, the flaky dust falls into the ash hopper, which purifies the flue gas passing through the electrostatic precipitator and meets the environmental protection emission standards. It is an ideal equipment for purifying industrial waste gases such as thermal power generation, metallurgy, papermaking, building materials, and non-ferrous metals.
After flue gas into the dust collector inlet ducts, through guide plate into the filter chamberthe flue gas flows from bottom up, through a bag filter, dust were stranded outside the bag, aftelpurification, the air is by net collection chamber, flue discharge from exports.
With the increase of dust thickness accumulated on the surface of the filter bag, the resistance ofthe dust collector rises gradually, and the resistance rises to a set value. The pulse injection valveopens automatically. The compressed air is ejected from the blowpipe through the nozzle, and thepurified flue gas is inducted into the inside of the filter baq, which causes the rapid expansion of thefilter bag. The dust attached to the filter bag is stripped off the cloth bag surface.
Technical Description
A、The determination of structure desian, the technical parameters and the selection of thefilter material make the equipment have high dust removal efficiency, which can ensure thatthe dust concentration of the outlet is less than 50mg/Nm3 or less than 30mg/Nm3 and belowthe more stringentemission requirements
B、The dust collector adopts the side air inlet mode, the air flow is evenly distributed and hasthe effect of pre dusting, which can effectively eliminate the " secondary adsorption'phenomenon of dust, improve the efficiency of dust cleaning and reduce the resistance ofequipment.
C、The pulse injection valve uses a low resistance submerged pulse valve. Compared withother products, diaphragm valve has the advantages of simple structure, reliableperformance, lower resistance, fast response speed, low gas consumption and moreeffective ash removal.
D、Each dust collector is divided into several independent filter chambers. When the on-linemaintenance is needed, the inlet and outlet doors of any filter chamber can be closed. Theboiler can be convenientlv maintained under the condition of 100% load.
E、The bypass flue of the dust collector is located inside the equipment and does notoccupy another site. The structure is compact and the daily operation and management areconvenient.By-pass valve zero leakagebypass flue gas without ash.
