DDF Large Bag Blowback Dust Collector

DDF large bag back blowing dust collector is a large-scale dust removal equipment with large air volume, good dust cleaning effect, good dust removal efficiency, stable operation, easy maintenance, and small footprint. The dust collector is mainly composed of an upper box, a middle box, an ash hopper, an inlet air equalizing pipe, a support filter bag and blowing device, an ash unloading device, etc.

The DDF large-scale bag back blowing dust collector is mainly composed of an upper box, a middle box, an ash hopper, an inlet air flow pipe, a support filter bag and blowing device, an ash unloading device, etc. It is widely used in steel mills, smelters, cement plants, carbon black plants, power plants and other enterprises for purifying and recovering smoke and dust generated by smelting, crushing, screening and combustion.

DDF large-scale bag back blowing dust collectors are widely used for dust control and material recovery in industries such as steelmaking, blast furnace raw material injection preparation, building materials, power, chemical, carbon black, asphalt concrete mixing, boilers, and flue gas dust removal in the metallurgical industry.

Structural characteristics of DDF large bag back blowing dust collector:

1. When the dust attached to the filter bag continues to increase and the resistance rises to the specified value, the cleaning process begins.

2. The accumulated dust inside the filter bag of the DDF large bag back blowing dust collector is shaken off and settled in the settling ash hopper, completing the cleaning of a single chamber. The other chambers are cleaned in the same sequence under the control of the cleaning actuator, and the cleaning stops when the determined value is reached.

3. The cleaning method of the DDF large bag type back blowing dust collector relies on the single chamber back blowing method. During the back blowing process, a reversing valve is used to close the exhaust pipe, open the back blowing pipe, and cut off the exhaust of the single chamber.

4. Because the inlet ducts of each room of the equipment are connected and in a negative pressure state, the negative pressure suction effect of adjacent rooms causes the airflow to be sucked into the filter bag chamber through the anti blowing duct. Through the filter bag, the airflow enters the inner side from the outside of the filter bag, passes through the ash hopper and the inlet duct of the room, and is sucked into the adjacent room for discharge. At this time, the filter bag is sucked in and deflated.
