DDF large bag back blowing dust collector
DDF large bag back blowing dust collector is divided into positive pressure type (also known as press in type) and negative pressure type (also known as suction type). This description is introduced according to negative pressure type
under the action of negative pressure, the DDF large back blowing bag filter enters the lower ash hopper from the air inlet pipe. The front of the air inlet is provided with a baffle plate, and the coarse dust falls into the ash hopper through collision and gravity. Fine particle dust is adsorbed on the inner wall of the filter bag after being filtered by the filter bag. The purified gas is sucked into the fan through the exhaust pipe through the switching valve on the top of the equipment, and then discharged into the atmosphere through the exhaust pipe
when the dust in the filter bag increases and the resistance rises to the specified value, start dust removal. The dust removal mode of DDF large back blowing bag filter depends on the single chamber back blowing mode. During reverse blowing, close the exhaust pipe through the reversing valve, open the reverse blowing pipe and cut off the exhaust of single chamber. Since the suction pipes of each room of the equipment are connected and in a negative pressure state, the negative pressure suction of the neighbor room can be reduced. The air flow is sucked into the filter bag chamber through the reverse blowing pipe. Through the filter bag, the air flow enters the inner side from the outside of the filter bag, and is sucked into the adjacent chamber through the ash hopper and the air inlet pipe of the room. At this time, the filter bag is absorbed. The dust in the filter bag trembles and falls into the dust resistance dust hopper to complete the dust in the single room. Under the control of the dust actuator, the same sequence of dust is carried out in the room. Dust removal value stops
DDF large back blowing bag vacuum cleaner is widely used in purification and recovery of smoke and dust generated by smelting, crushing, screening and combustion in steel mills, smelters, cement plants, carbon black plants, power stations and other enterprises. DDF large back blowing bag filter is an equipment to protect the physical and mental health of workers and people, crop growth and development, mechanical equipment wear, social environmental pollution and useful dust recovery cost
the arrangement number of filter bags is 1000m2, which is the arrangement number under 2W configuration, and 3000-9000m2 is the arrangement number under 2w4w configuration. 1800m2 is the number of rows under the 3w3 configuration, which is 10000 M. the other is the number of rows under the surrounding channel configuration. W indicates the inspection channel
the inlet temperature is 729 and 734. Nylon cloth can withstand 150 ℃ and glass fiber cloth treated for three generations can withstand 150 ℃
