1, the local dust extraction system, decentralized dust extraction system and centralized dust extraction system 

dust extraction system in accordance with the size and configuration characteristics, can be divided into in situ dust extraction system, decentralized dust extraction system and centralized dust extraction system three types. Design should be based on the production process, the configuration of the process equipment, plant conditions and the size of the dust exhaust air, etc., were selected.In-place dust extraction system The dust collector in the system is located directly on the dust removal point, in situ to absorb and purify dust.

2, dry dust extraction system and wet dust extraction system

dust extraction system according to the selection of dust removal equipment can be divided into dry dust system and wet dust collector system two types.

3, negative pressure dust extraction system and positive pressure dust extraction system

dust extraction system in accordance with the dust collector and fan in the process of the relative position, can be divided into negative pressure dust extraction system and positive pressure dust extraction system .

4, single-stage dust extraction system and multi-stage dust extraction system

dust extraction system in accordance with the use of the number of dust collector, can be divided into single-stage dust extraction system and multi-stage dust extraction system
