Cleaning method of industrial filter bag
Industrial filter bag should be reasonably selected to clean the ash, to meet the requirements of cleaning the ash, industrial filter bag to maintain the economic operation of the resistance of 800-1500pa, in addition to the reasonable selection of cleaning the ash, industrial filter bag is required to be easy to clean the ash; To meet the requirements of air permeability, the air permeability of industrial filter bag is an important filtration performance, and the water absorption of industrial filter bag has a decisive influence on air permeability. Natural fiber and organic synthetic fiber, at room temperature, have the characteristics of absorbing moisture in the dust gas, so adhere to dissolve dust in the dust gas, accumulation in the filter bag or further chemical changes gradually lose permeability, thereby reducing or even losing the filtration function, so that must be removed to clean or replace the filter bag.
To meet the requirements of dust removal efficiency. Generally speaking, the structure of industrial cloth should be selected according to the strength of the filter bag. If the dust removal intensity is large, if the compressed air pulse is used, the leftovers dust layer on the filter bag will be blown off, and the dust removal efficiency string is completely maintained by the compacting degree of the shaft filter cloth, then the industrial cloth is generally required to be relatively raw and the dust surface has nap. The presence of villi on the surface of the filter bag can increase the surface accumulation of trapping particles. Provides interpore support to prevent accumulated ash clumps from penetrating into pores to form loose layers; When the filter bag is cleaned, it is helpful to maintain the layer and increase the initial effect.
