After the dust-laden gas enters the ash hopper from the tuyere, a
part of the coarser dust particles and condensed dust clusters
directly fall down due to the inertia effect and play the role of
pre-collecting dust. The airflow entering the ash hopper turns
upwards and flows into the box. When passing through the filter bag
with a metal frame inside, the dust is blocked on the outer surface
of the filter bag. The purified gas enters the clean room on the
upper part of the filter bag and is collected in the air outlet
pipe and discharged.
The bag filter is a dry dust removal device, which is suitable for
collecting small, dry non-fibrous dust. It can be used in the
following areas.
1. Smoke from ironworks, steelworks, ferroalloy plants, refractory
plants, foundries, power plants, etc.;
2. Waste incinerator, coal-fired boiler, fluidized bed boiler flue
gas;
3. Asphalt concrete mixing, building materials, cement ceramics,
lime, gypsum and other dust;
4. Smelting flue gas from aluminum electrolysis, lead, tin, zinc,
copper and other rare metals;
5. Recycling of fine materials in the fields of chemicals, coke,
carbon black, dyes, plastics, etc.;
6. Dust from mining, grain processing, flour, electronics industry,
wood processing, etc.
