Purification of dust - containing gas in pulse bag dust collector

Purification of dust - containing gas in pulse bag dust collector

The main difference between the structure of pulse bag dust collector and the general bag dust collector is that the porous separator of the filter bag is fixed in the upper half of the box body: a frame is installed in the filter bag to prevent the filter bag from being sucked by negative pressure. In order to increase the blowback ability, the upper mouth of the filter bag is equipped with a Winsley tube to induce air volume; The nozzle is fitted to the top of the Venn tube. Pulse injection is a signal sent by the controller, and the filter bag is cleaned regularly through the actuator.

Its dust removal principle is: The dusty gas enters the dust collecting box from the air inlet. Due to the sudden decrease in speed, some of the heavy particles of dust are separated by their own weight and fall into the dust collecting bucket. The dusty gas continues to flow upward and gradually passes through the filter bag. Through the pipe into the clean gas box, from the clean gas outlet. As the dust on the filter bag is gradually thickened, the pressure loss of the dust collector is increasing, and the amount of gas treated is gradually reduced.

In order to make the dust collector working condition stable, please return to the system by spraying, and spray compressed air into the filter bag according to the requirements to remove the dust, so that the filter bag, the output of gas is stable. The removed dust falls into the dust collector and is continuously discharged from the body through the ash removal device.
