Product Details

The efficient bag-type dust collector for mining is a new type of pulse dust collector that has been improved based on the ordinary bag-type dust collector. It integrates the advantages of various pulse jet dust removal systems with multiple chambers, overcoming the shortcomings of insufficient cleaning intensity and uneven air distribution in the chambers. This has expanded its application scope. The pulse bag-type dust collector enhances the dust collection efficiency and adaptability. 

Working principle of bag dust collector:

When the dusty gas enters the dust collector through the inlet, the airflow turns and flows into the ash hopper. At the same time, the airflow speed slows down. Due to the inertia effect, the coarse dust particles in the gas directly flow into the ash hopper. This serves as a pre-dust collection function. The airflow entering the ash hopper then bends upward and passes through the filter bags inside, which are equipped with metal frames. The dust is captured on the outer surface of the filter bags. The purified gas then enters the upper clean chamber of the filter bag chamber and is collected and discharged through the outlet. During the process of the dusty gas being purified by the filter bags, the dust adhering to the filter bags increases with the passage of time. This increases the resistance of the filter bags, causing the processing air volume to gradually decrease. For normal operation, the resistance must be controlled within a certain range (140 - 170 millimeters of water column). To clear the dust from the filter bags, the pulse control instrument sequentially triggers each control valve to open the pulse valve. The compressed air in the air bag is sprayed through the holes of the blow-off pipe through the Venturi tube into each corresponding filter bag. The filter bag suddenly expands rapidly, causing the dust adhering to the surface of the filter bag to fall off. The filter bag is then regenerated.
