In order to create a good working environment for workers and reduce the probability of occupational diseases, it is necessary to do a good job in dust control in the production process of mines, to effectively control the dust at the point of dust production, so that it does not spread to the surroundings, and eliminates dust hazards, so as to achieve The coordinated development of mineral resources development and ecological environment protection.

In the prior art, the treatment of dust pollution is mainly achieved by collecting or reducing the content of solid particle pollutants in the air by specific methods. When the required air volume meets the requirements, the dust collector is a key component, and the effect of the dust collector directly affects the improvement of the environmental quality. At present, bag type dust collectors are mostly used in the treatment of this kind of dust. Bag type dust collectors are widely used for their high efficiency, strong dust adaptability, and large processing air volume. Difficult, especially when the dust is relatively humid, the use of compressed air to remove dust will affect the service life of the filter material. Therefore, it is very meaningful to study a new technology equipment that is economical, simple, high dust removal efficiency and good dust removal effect to improve the working environment of the operator and protect the health of the employees.

The filter cartridge dust collector has the function of a bag filter, and its filtration speed is high.
