Large bag type backflush dust collector Large bag type backflush dust collector is widely used in the purification and recovery of smoke and dust generated by smelting, crushing, screening and combustion in steel plants, smelting plants, cement plants, carbon black plants, power stations and other enterprises.
Product details
Detailed introduction of large bag type backflush dust collector:
Large bag type backflush dust collector is widely used in smelting, crushing and screening in steel plants, smelting plants, cement plants, carbon black plants, power stations and other enterprises. and the purification and recovery of smoke and dust generated by combustion. It is an effective equipment to protect the physical and mental health of operators and people, the wear and tear of crop growth machinery and equipment, the pollution of the social environment, and the recycling of useful dust to reduce costs. The inlet temperature and polyester cloth are temperature-resistant ℃. The glass fiber cloth processed by three generations is temperature-resistant ℃. .
Working principle of large bag type backflush dust collector:
Large bag type backflush bag dust collector is divided into positive pressure type (also called pressure-in type) and negative pressure type (also called suction type). This manual Introduced by negative pressure type.
It means that dust-containing gas enters the ash hopper from each air inlet pipe under the action of negative pressure. There is a baffle plate at the air inlet. The coarser dust falls into the ash hopper by gravity, and the fine dust is removed. The filter bag filters and is adsorbed on the inner wall of the dust filter bag. The purified gas passes through the clean air chamber, is sucked into the fan through the exhaust pipe through the switching valve at the top of the equipment, and then is discharged into the atmosphere through the exhaust pipe.
Structural features of large bag type backflush dust collector:
When the dust attached to the filter bag continues to increase and the resistance rises to a specified value, dust cleaning begins.
The dust cleaning method of large bag type back-blowing bag dust collector relies on single-chamber back-blowing. During back-blowing, the exhaust duct is closed through the reversing valve, the back-blowing duct is opened, and the exhaust air in the single chamber is cut off.
Because the air inlet ducts in each room of the equipment are connected and are all in a negative pressure state, due to the negative pressure suction effect of the adjacent room, the air flow is sucked into the filter bag room through the backflush duct and penetrates the filter bag. The air flows from the outside of the filter bag into the inside, and is sucked into the adjacent room through the ash hopper and the air inlet pipe of the room and discharged. At this time, the filter bag is deflated.
The accumulated dust inside the filter bag is then shaken off and settles into the settling ash hopper, completing the dust cleaning of the single chamber. Under the control of the dust cleaning actuator, the other chambers are cleaned in the same sequence, except for When a certain value is reached, dust cleaning stops.
