DDF Large bag type reverse blowback dust catcher

DDF large-scale bag-type reverse blowing dust catcher is a large-scale dust catcher with large handling air volume, good dust cleaning effect, high dust removal efficiency, reliable operation, convenient maintenance and small footprint. The dust collector mainly consists of upper box, middle box, ash hopper, air inlet equalization pipe, support filter bag and blowing device, ash discharge device and other components.

Graphic Details

DDF large-scale bag-type blowback dust collector is widely used in metallurgical industry, steelmaking blast furnace raw material coal injection preparation and other plants, building materials industry, electric power, chemical industry, carbon black, asphalt and concrete mixing, boiler, flue gas dedusting and other industries of dust management and material recovery.

DDF large-scale bag-type blowback dust collector structure features:

1、The dust attached to the filter bag increases constantly, and when the resistance rises to the specified value, it starts to clear the dust.

2, DDF large bag blowback dust collector filter bag inside the dust is then shaken off to sink to the precipitation hopper, completed a single room cleaning, the rest of the room under the control of the cleaning actuator, the same sequence of cleaning, in addition to a certain value, the cleaning stops.

3, DDF large-scale bag-type blowback dust collector cleaning method by single-chamber blowback mode, blowback through the reversing valve, close the exhaust pipe, open the blowback pipe, cut off the exhaust of a single room.

4、Because the inlet ducts of each room of the equipment are connected, and they are all in negative pressure, so due to the negative pressure suction effect of the neighboring room, so that the airflow is sucked into the filter bag room through the reverse blowing ducts, and the filter bags are filtered, and the airflow enters into the inner side from the outside of the filter bag, and is sucked into the neighboring room through the dust hopper and the inlet ducts of this room, and the bags are sucked into the flat at this time.
