Product parameter:
Impusle bag dust collector has been updated and kept high efficient purification. It has the capability to handle large volumn gas. With the features of stable performance,long sevice lifetime, convenient operation and maintenance, it is widely applicable to machining, metallurgical, rubber, powder, chemical, pharmaceutical, carbon materials, building and mining industries etc. as well as favoured by customers from all of the world.
Characteristic:
v1,Large air volume treatment,high efficient dust collecting.
v2,1000g/Nm3 dusty air is ok, and after processing the gas emission concentration is below 50mg/Nm3 .(to meet more stringent emission standard by your request is available)
v3,Using reasonable air inlet type to avoid secondary dust flying effectively.
v4,For different types of fume or dust, we use different materials of filter bags to satify special emission requirement.
v5,Bag filter cage with venturi to improve de-dusting efficiency and protect filter bags.
v6,Using advanced pulse valve, reliable preformance & long lifetime ( can be used 1,000,000 times)
v7,Timing or setting resistance automatic blowing deashing by PLC controller, which has small gas consumption,soot cleaning thoroughly and reliable property.
v8,Can be checked and maintained during working, such as replace filter bags in separate chamber without disturbing the host operation.
filtration process:
Working principle:
1) By the attraction of induced draft fan, the dusty air is absorbed into ash bucket,through the effection of air deflector, the gas is distributed evenly onto each filter bag, then corase particles are intercepted in the outer surface of filter bag, but clean air will pass through and be discharged into the air.
2)The dust on the surface of filter bag will reduce permeability that leads to resistance increase of dust collector,so when it reach to set value (resistance or time),the pulse valve will be opened a short time(about 0.1s) under controlled by PLC, the high pressure gas instantly from air bag into injection pipe, and blowing out through injection holes in high speed.
3)When this high speed gas blows into filter bag, secondary airflow will generate, under their combined effection, filter bag inner pressure rapidly rise to make filter bag become convex,and when this deformation reach up to maxium value,it produce reverse acceleration, which helps to peel off dust from surface of filter bag.
