he role of ash layer in the dust removal process of nylon filter cloth
The ash layer on the surface of the filter cloth consists of dust particles of different sizes. It has various structural properties and pore properties. Under normal conditions, it affects the dust removal efficiency and resistance of the bag filter and determines the running performance. The filter cloth is a skeleton that forms a dust layer and supports a dust layer.
Professional manufacturer maishi nylon filter cloth. The quality of nylon filter cloth is internationally certified. We produce nylon filter cloth more professional and safer.
1) When the ash layer is thick enough
, high dust removal efficiency can be achieved.
(2) When the ash layer is thin or porous, the gas permeability is good, and the dust removal resistance and dust removal efficiency are low.
(3) When the ash layer is sticky, it is not easy to be cleaned and the resistance is high.
(4) When the ash ratio is large, the inertia of the ash is large, and it is easy to separate from the surface of the filter bag after being oscillated, and the ash cleaning effect is enhanced.
The extent to which the remaining ash layer enters the inside of the filter cloth or is attached to the surface of the filter cloth directly affects the resistance of the dust remover and the dust removal efficiency.
