The dust collector in the stone factory has a new type of advanced dust collector that combines the advantages of chamber back blowing and pulse blowing dust removal, fully overcoming the disadvantages of poor intensity of chamber back blowing dust removal and simultaneous operation of pulse blowing dust removal and filtration, and expanding the application range of sub bag dust collectors. Due to the unique structure of the dust collector in the stone factory, the dust removal efficiency has been improved and the service life of the equipment filter bag has been extended. It is a high-performance bag filter. Widely used in building materials, cement, metallurgy, mining plants, and refractory materials industries.

The bag filter used in stone factories has the advantages of simple structure, low investment cost, easy operation, and low requirements for management and maintenance technology. This type of dust removal equipment has the characteristics of low resistance, high dust removal and processing air volume, stable performance, small footprint, simple structure, practicality and low cost. After the dust containing gas enters through the upper air inlet of the ash hopper, the airflow moves upward under the action of the wind deflector, and the flow velocity decreases. Some large particles of dust are separated and fall into the ash hopper due to the inertia force.

During the process of flue gas containing dust entering the middle and lower boxes through the inlet of the dust collector, the dust is adsorbed on the dust removal filter bag, and the gas enters the upper box through the filter bag through the Venturi tube and is discharged from the outlet. As the dust accumulates on the filter bag, the pressure loss of the filter bag gradually increases, and this pressure loss is fed back to the control instrument by the pressure gauge. The control device receives and sends instructions to trigger each pulse solenoid valve in sequence, causing the gas in the air bag to instantly spray out from the holes of the spray pipe and into the corresponding filter bag. The filter bag expands under the reaction of the airflow, causing the dust accumulated on the surface of the filter bag to fall off, and the filter bag is reused.
