LPM pneumatic bag filter

The high dust removal efficiency of LPM pneumatic bag filter is inseparable from its dust removal mechanism. When the dusty gas enters the ash hopper through the lower intake pipe of the dust collector and the guide plate, due to the collision of the guide plate and the decrease in gas velocity, coarse dust particles will fall into the ash hopper, while the remaining fine dust particles will enter the filter bag chamber with the gas. Due to the inertia, diffusion, barrier, hooking, static electricity and other effects of the filter fiber and fabric, the dust is trapped in the filter bag, and the purified gas escapes from the bag and is discharged through the exhaust pipe. The accumulated dust on the filter bag is removed by gas backwashing method, and the removed dust is discharged to the ash hopper and discharged to the ash conveying device through the double-layer ash discharge valve. The dust accumulation on the filter bag can also be removed by spraying pulse airflow to achieve the purpose of cleaning, and the removed dust is discharged by the ash discharge device. The high dust removal efficiency of a bag filter is also inseparable from the filter material. The performance and quality of the filter material directly affect the performance and service life of the bag filter. The filtering material is the main material for making filter bags, and its performance and quality promote the progress of bag dust removal technology, affecting its application scope and service life.
LPM pneumatic bag filter is a bit
⑴ The dust removal efficiency is high, generally above 99%. The dust concentration in the outlet gas of the dust collector is within tens of mg/m3, and it has a high classification efficiency for fine dust with sub micron particle size.
⑵ The range of air volume processing is wide, ranging from a few cubic meters per minute for small ones to tens of thousands of cubic meters per minute for large ones. It can be used for dust removal of flue gas in industrial furnaces and kilns, reducing the emission of atmospheric pollutants.
⑶ Simple structure, easy maintenance and operation.
On the premise of ensuring the same high dust removal efficiency, the cost is lower than that of electrostatic precipitators.
When using high-temperature resistant filter media such as glass fiber, polytetrafluoroethylene, P84, etc., it can operate under high temperature conditions above 200 ℃.
(6) Not sensitive to the characteristics of dust and not affected by dust and resistance.
