Furniture factory pulse bag type dust collector is when the dust-laden gas enters the dust collector from the air inlet, and first encounters the inclined plate and baffle plate in the middle of the air inlet and outlet, the air flow turns to flow into the ash hopper, and the air flow speed slows down. The coarse dust in the gas flows directly into the ash hopper. It plays the role of pre-dust collection. The airflow entering the ash hopper is then folded upward and passes through the filter bag with a metal frame inside. The dust is collected on the surface of the filter bag. When the dust-containing gas is discharged from the air outlet and the dust-containing gas is purified by the filter bag, more and more dust accumulates on the filter bag with the increase of time, which increases the resistance of the filter bag and causes the disposal air volume to gradually decrease. In order to work normally, it is necessary to control If the resistance is within a certain range (140--170 mm water column), it is necessary to stop cleaning the filter bag. When cleaning the dust, the pulse controller will trigger each control valve to open the pulse valve one by one. The tube is radiated into each corresponding filter bag, and the filter bag shrinks suddenly, so that the dust accumulated on the surface of the filter bag is scattered, and the filter bag is regenerated. The cleaned dust falls into the ash hopper and is discharged from the body through the ash discharge system.
   
    Characteristics of pulse bag filter in furniture factory;
   
    1. The dust collector adopts the technology of sub-chamber air stop and pulse jet dust cleaning, which overcomes the defects of conventional pulse dust collector and sub-chamber back-flushing dust collector. It has strong dust cleaning ability, high dust removal efficiency, low emission concentration, low air leakage rate and energy consumption. Less steel consumption, less space occupation, stable and reliable operation, and good economic benefits. It is suitable for the purification of dusty gas and the recovery of materials in furniture, woodworking, food, hardware, plastic, metallurgy, building materials, cement, machinery, chemical industry, electric power, and light industry.
   
   
    2. Due to the use of sub-chamber air-stop pulse injection to clean the dust, the purpose of complete dust cleaning can be achieved by one injection, so the cleaning cycle is prolonged, the energy consumption of dust cleaning is reduced, and the consumption of compressed air can be greatly reduced. At the same time, the fatigue level of the filter bag and the pulse valve is also reduced accordingly, thereby multiplying the life of the filter bag and valve plate.
   
   
    3. The maintenance and replacement of bags can be done without stopping the fan of the system, and the room can be stopped under the normal operating conditions of the system. The mouth of the filter bag adopts an elastic expansion ring, which has good sealing performance and is firm and reliable. The filter bag keel adopts polygonal shape, which reduces the friction between the bag and the keel, prolongs the life of the bag, and facilitates the unloading of the bag.
   
   
    4. The upper part of the bag is drawn. After the skeleton is pulled out when changing the bag, the dirty bag is put into the ash hopper at the lower part of the box and taken out from the manhole, which improves the operating conditions of changing the bag.
   
   
    5. The box body adopts air-tight design, which has good sealing performance. The inspection door uses excellent sealing materials. In the manufacturing process, kerosene is used for leakage detection, and the air leakage rate is very low.
   
   
    6. The inlet and outlet air ducts are compactly arranged, and the airflow resistance is small.
