How to use filter bags
2013-07-13 10:27:00

The filter enclosed filter: filter bag and supporting the filter at the same time, the use of the system fluid pressure, the liquid is extruded through a filter bag, in order to achieve the purpose of filtering. Has the flow speed large capacity, long life filter bag advantages, especially suitable for the large flow must be sealed filter occasions.
The artesian open filter: bag suitable connector directly connected to the pipeline, starting fluid gravity differential pressure filter. Its distinguishing feature is without investment in equipment, the filter is simple and feasible, especially suitable for small size, various kinds of, intermittent economic type liquid filtration.
Baghouse is a dry dust filter device. It is suitable for trapping a small, dry, non-fibrous dust. The bag textile cloth made of felt or non-woven fabric filter dust-laden gas filter, when the dusty gas enters the baghouse, the large particles, than the major dust due to gravity role in settling down into the hopper, contains smaller dust gas through the filter, dust retention, so that the gas to be purified. Most of the new filter collection efficiency is not high enough. Filter used for some time, due to the sifting, collision, retention, diffusion, the effect of static electricity, etc., the accumulation of the surface of the bag with a layer of dust, dust is referred to as a First layer this layer, in this movement process, the primary layer became main filter layer of the filter, relying on the role of the primary layer, the larger the mesh filter to obtain a high filtration efficiency. With the accumulation of dust in the filter surface, the efficiency of the precipitator and resistance corresponding increase in some of the fine dust particles attached to the filter on when the differential pressure on both sides of the filter, will squeeze past, precipitator efficiency is decreased. In addition, the high resistance of the precipitator dust removal system air volume will significantly decline. Therefore, the the precipitator resistance reaches a certain value, timely cleaning. Cleaning can not be destroyed when the primary layer, so that the efficiency is decreased.
The baghouse structure is dominated by the part of the upper tank, the central box, lower box (hopper), cleaning system and ash institutions.
The baghouse performance is good or bad, in addition to the correct choice of bag material, the cleaning system of baghouse plays a decisive role. To this end, the cleaning method is one of the characteristics that distinguish the baghouse, also baghouse run.
