Bag Filter Dust Collector
LCDM Series Baghouse Filter (Bag Filter Dust Collector) is specially developed for the needs of large-scale air purification of pulse bag filter. It not only has the characteristics of strong dust collection ability, high-efficient dust removal and low emission concentration, but also has the advantages of stable and reliable, low gas consumption, small cover area; especially suitable for processing large volume of flue gas. LCDM series low-pressure pulse dust collector has been applied throughout the world. It also has a large number of promotions in China, which is widely used in utility boiler, industry boiler, metallurgy, machinery, chemical industry, and building materials industries.
Baghouse Filter (Bag Filter Dust Collector) is mainly composed of upper-enclosure, middle-enclosure, ash hopper, discharge system and control system and other several parts, and adopts the structure of inlet chamber. Dusty gas enters into the hopper from inlet via middle-enclosure, part of the larger dust particles naturally settle down in ash hopper due to the inertia collision. Other small dust particles rise with the air currents entering into the different rooms. After purification, dust is trapped on external surface of the filter bag.The purified air is finally discharged into the atmosphere by induced draft fan passing from inner filter bag via the mouth, upper-endosure.
Enclosure is mainly used to fix bag cage, filter bag and pneumatic components so that it can make full closed state, compressed air enters into the enclosure and then enters into the filter bag during dust removal.There is a manhole access door at the top of enclosure, it is very convenient to install and replace the bag cage or filter bag here.According to different specifications, the off-line air impulse bag filter enclosure can be divided into several chambers which are separated with steel plates and air-tight between each other in order to realize the off-line dust removal. Each chamber has a lifting valve to cut off the filtered air during dust removal.
Chamber of air impulse bag filter is at the top of the enclosure, it is mainly used to hold the filter bag and form a filter space where the flue gas purification process is mainly on here. According to different specifications, chamber is also divided into several rooms which is separated with baffle plate in order to prevent the mutual interference between each other during dust removal. It forms a certain settlement space as well.
Ash hopper is at the bottom of the bag chamber, it does not only store collected dust, but it is also used as inlet manifold. Great volume of ash hopper makes lower air velocity and the change of airflow direction before dusty gas enter into the bag chamber, as a result, coarser particles can be removed. There is transportation equipment at the bottom of ash hopper such as screw conveyor or air chute and so on, at the same time, ash outlet is installed with rotary unloading or air-lock devices like flap valve to ensure continuous ash discharging.
According to different Bag Quantity, Plenum Pulse Dust collector could be classified as 32bags/room, 64bags/room,96bags/room,128bags/room. Each kind will be divided into many different type-33 kinds in total.
