- Application: dust collection for low-oxidizability gas from garbage incinerator, metal melting, steel plants, coal-fire boiler and chemical industry; dust collection for high temperature gas such as blast-furnace gas, electric furnace exhaust, etc.
Dust collector bags
- The dust collector bag is the core element of the filter-type dust collector.
- Usually the cylindrical impulse-type dust collector bag is suspended in the dust collectors vertically. Dust gas enters the dust collector bag from the air inlet and the passage board, big dust particles were filtered out into the dust hopper directly by inertia. When dust gas reached the filtering area of the box, dust is captured on the outer surface of the dust collector bags, and gas flows into the pocket through filter media, then purified gas discharges from the outlet.
