Filter cloth is the most important part of the bag filter, the filter cloth properties in addition to the nature of the fiber itself (such as temperature, corrosion resistance and mechanical strength, etc.), but also with the surface structure (textured, with hair) and Degree related. Temperature, resistance to installation tension is the basic requirements of the filter cloth,
Bag filter dust removal process on the basic requirements of the filter cloth
(1) To meet the dust removal efficiency requirements. In general, should be based on the size of filter bag friend strength, the structure of the selected filter cloth. Cleaning strength, such as the use of compressed air pulse backflushing, the filter bag is attached to the ash layer is spray off, the dust removal efficiency in full accordance with the density of the filter cloth to maintain the level, the general requirements of the filter cloth 庠 and welcome Dust surface with fluff. Fluff on the surface of the filter bag can increase the surface area of the captured particles; provide support between the holes to prevent the accumulated gray matter from entering the pores to form a loose layer; and when the filter bag is cleaned, The structure contributes to the retention of the prickle ash layer and increases the initial efficiency.
(2) to be able to meet the cleaning requirements, the filter cloth to maintain economic resistance of 800-1500pa, in addition to a reasonable choice of cleaning methods, but also requires easy cleaning of the filter cloth.
(3) to meet the air permeability requirements, fabric filter cloth breathability is an important filtration performance, the water absorption of the cloth has a decisive influence on breathability. Natural fibers and organic synthetic fibers, at room temperature, have the characteristics of absorbing moisture in dust-laden gases, thus adhering dusts in dust-laden gases, accumulating on the filter bag or even further losing chemical permeability and thus decreasing air permeability Even lose the filter effect, which must be removed to clean or replace the filter bag.
