As the name implies, dust remover is the dust removal equipment for handling flue gas dust. Different dust has different influence on the design and operation of dust removal equipment. The performance of dust collector is expressed by the volume of process gas and the resistance loss of equipment.

Bag filter is a kind of dry dust filter, which is suitable for collecting fine, dry and non fibrous dust. The filter bag is made of woven filter cloth or non-woven fabric, and the filtering effect of fiber fabric is used to filter dust containing gas. When the dust containing gas enters into the bag filter, the dust with large particles and large specific gravity will fall into the ash hopper due to gravity settlement. When the gas containing small dust passes through the filter material, the dust is blocked, so the gas is purified and discharged up to the standard.
Dust collectors are widely used in concrete mixing plant, main mine dust control, workshop dust control and grinding and cutting dust production point dust control.
Now let's talk about the concept of dust and dust in dust collector.
1. Dust is a small solid molecule suspended in the air. When the solvent evaporates, the solute condenses, such as paint dust produced by paint operation. The solid particles formed by mechanical impact, grinding and rolling of solid materials are dispersed by airflow and suspended in the air. This is called dust. The particle size is about 0.25-20 μ m, most of which are 0.5-5 μ M.
2. Smoke is the unburned particles produced by materials (feed, wood, oil, coal, etc.), or the black smoke produced by residual unburned ashes is usually called smoke. Its particle size is very fine, even less than 0.5 micron.
3. Smoke and dust are solid particles produced by physical and chemical processes, which are called smoke and dust. For example, dust particles formed by sublimation and condensation during melting, combustion and metal welding. Its particle size is usually smaller than 1.0 μ M
