Bag type back blowing dust collectors are divided into positive pressure (also known as compression type) and negative pressure (also known as suction type).

When the dust attached to the filter bag of the bag type back blowing dust collector continues to increase and the resistance rises to the specified value, the dust cleaning begins. The equipment's dust cleaning method relies on the single chamber back blowing method. During the back blowing, the reversing valve is used to close the exhaust pipe, open the back blowing pipe, and cut off the exhaust of the single chamber. Because the inlet pipes of each chamber of the equipment are connected and in a negative pressure state, the bag type back blowing dust collector, due to the negative pressure suction effect of the adjacent chamber, causes the airflow to be sucked into the filter bag chamber through the back blowing pipe. Through the filter bag, the airflow of the bag type back blowing dust collector enters the inner side from the outside of the filter bag, passes through the ash hopper and the inlet pipe of the chamber, and is sucked into the adjacent chamber for discharge. At this time, the filter bag is sucked in and the accumulated dust After settling in the settling ash hopper, the cleaning of a single room is completed. The other rooms are cleaned in the same sequence under the control of the cleaning actuator. When the value is reached, Stop cleaning the dust.

Under negative pressure, the dust containing gas in the bag type back blowing dust collector enters the lower ash hopper through the inlet duct. The bag type back blowing dust collector is equipped with a baffle plate on the front of the inlet duct. Coarse dust falls into the ash hopper by collision and gravity, while fine particle dust is filtered by the filter bag and adsorbed on the inner wall of the filter bag. The purified gas passes through the bag filter chamber and is sucked into the fan through the exhaust pipe through the top switching valve of the equipment, and then discharged into the atmosphere through the exhaust pipe.
