Filter dust removal is to make the dusty gas through the porous filter media, the dust particles in the gas to stay, so that the gas is purified dust removal device.
Mechanical dust removal is relying on mechanical force (gravity, inertia, centrifugal force, etc.) to remove dust particles from the gas stream device. Characterized by simple structure, equipment costs and operating costs are low, but the dust removal efficiency is not high. According to the different dust particles can be designed as gravity dust fall chamber, inertia dust collector and cyclone dust collector. It is suitable for airflow with high dust concentration and large particle strength. Widely used in dust removal requirements are not high occasions or used as a high-efficiency dust removal device of the front pre-dust collector.
The bag type dust collector is a kind of dry type dust filtering device. It is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, the use of fiber fabric filtration effect on the dusty gas filtration, when the dusty gas into the bag filter, particles of large, large dust, due to the effect of gravity settling down into the dust hopper, containing finer dust gas through the filter media, the dust is retained, so that the gas is purified.
