The dust collector in the cement grinding station is a multi chamber unit dust removal unit. It isolates and stops the air in each chamber, and the control cabinet releases pulse signals to clean the wheel chamber dust. It adopts the design concept of high air volume and low filtering air speed, and adopts the dust removal technology of settling flow and secondary diversion. While playing the role of pre dust collection, it also ensures the smooth and uniform air inlet of the unit, improving the working efficiency of the equipment.

The structural characteristics of the grinding station:

(1) Main body: consisting of an upper box, a clean air chamber, and a ladder guardrail;

(2) Filtering system: including skeleton, filter bag components;

(3) Dust cleaning system: including electromagnetic pulse valve, air bag, and spray pipe;

(4) Induced draft system: including induced draft fan, fan connection flange;

(5) Control system: including pulse program controller and starter cabinet;

working principle:

The dusty air enters the dust collector box from the bottom of the dust collector. Coarse particles of dust settle down by their own gravity and fall into the ash bin. Fine dust is adsorbed on the outer wall of the filter bag through various effects. The purified air filtered by the filter bag enters the clean air chamber through the Venturi tube and is discharged from the outlet. The dust adsorbed on the outer wall of the filter bag accumulates thicker over time, and the resistance of the dust collector gradually increases, resulting in a continuous decrease in the amount of gas processed. In order to maintain the working state of the dust collector regularly and keep the pressure loss within a certain range, it is necessary to clean it; Clean up the accumulated dust on the surface of the filter bag.

The dust cleaning process is carried out by the control instrument issuing instructions to each electromagnetic pulse valve according to the specified requirements, opening the valves in sequence, and spraying high-pressure air into each group of filter bags in sequence. The compressed air in the air bag passes through the holes of the blowing tube and enters the filter bag through the Venturi tube (called primary air). When the high-speed airflow sprayed passes through the Venturi tube, several times the surrounding air of the primary air is induced to enter the filter bag at the same time (called secondary air). Due to the strong reverse airflow formed by the primary and secondary winds, which is opposite to the filtered airflow, entering the filter bag, the filter bag rapidly expands and contracts in an instant, and the reverse effect of the airflow clears the dust adsorbed on the surface of the filter bag.

Due to the fact that the high-pressure air sprayed into the filter bags during dust cleaning is carried out sequentially between several groups of filter bags without cutting off the dusty air that needs to be treated, the pressure loss of the dust collector and the amount of dusty gas being treated remain almost unchanged during the dust cleaning process. This is one of the characteristics of pulse bag filters.

Characteristics:

1. External filtration, offline dust cleaning, no dust accumulation, and increased resistance caused by bag sticking.

2. The dust collector flower board is made by a new type of laser cutting, which makes the bag and flower board tightly connected and the clean air chamber clean.

3. Control, simple operation, stable operation.

4. The use of high configuration components has improved operational stability and reduced maintenance workload.

5. Huiyang Company has experience in producing mill dust collectors, mature technology, equipment, and low prices.
