Large bag type backflush/dust collector
Detailed introduction
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 device to protect the physical and mental health of operators and people, the growth of crops, the wear and tear of mechanical equipment, the pollution of the social environment and the recycling of useful dust to reduce costs. The entrance temperature and polyester cloth temperature resistance ℃, the glass fiber cloth after three generations of treatment is resistant Temperature ℃.
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 refers to negative pressure type. Type introduction.
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 particles fall into the ash hopper by gravity. The dust is filtered by the dust filter bag and adsorbed on the inner wall of the dust filter bag. The purified gas passes through the clean air chamber, is inhaled into the fan through the exhaust pipe through the switching valve at the top of the equipment, and is then discharged into the atmosphere through the exhaust pipe.
Structural features of large bag type backflush dust collector
, The dust attached to the filter bag continues to increase, and when the resistance rises to a specified value, dust cleaning begins.
, Dust cleaning of large bag type backflush bag dust collector The method relies on the single-room back-blowing method. During back-blowing, the air is passed through the reversing valve, the exhaust duct is closed, the back-blowing duct is opened, and the exhaust air in the single room is cut off.
Because the air inlet ducts in each room of the equipment are connected, And they are all in a negative pressure state. Therefore, due to the negative pressure suction effect of the adjacent room, the airflow is sucked into the filter bag chamber through the backflush duct. Through the filter bag, the airflow enters from the outside of the filter bag to the inside, and passes through the ash hopper and the inlet of the chamber. The air duct is sucked into the adjacent room and discharged. At this time, the filter bag is sucked and deflated.
The dust inside the filter bag is shaken off and settles into the settling ash hopper, completing the cleaning of the single room, and the remaining rooms are in Under the control of the cleaning actuator, the same sequence of dust cleaning is carried out. When the dust reaches a certain value, the dust cleaning stops.
