1、 Dust treatment in plastic granule factory

Effective selection of dust removal equipment: the selection of dust treatment machinery and equipment must master the composition of dust and its application and working conditions. The scenarios available for different dust treatment equipment are also different. At this stage, the solutions to dust generally include cyclone dust removal, bag type dust collector, wet dust removal, etc

2、 Pulse dust collector, bag dust collector, single bag dust collector

Pulse dust remover is a dust remover that takes compressed air as the dust removal power, uses the pulse injection mechanism to release compressed air in an instant, induces several times of secondary air to ingest the filter bag at a high speed, causes the filter bag to expand rapidly, and cleans the dust by means of impact vibration and reverse air flow. The pulse type dust collector is an effective dust removal and purification equipment. It adopts the pulse injection dust removal method, which has the advantages of good dust removal effect, good purification efficiency, large processing gas volume, long filter bag life, small maintenance workload, safe and reliable operation, etc; However, compressed air is required, and when the supplied compressed air pressure cannot meet the requirements, the return effect will be greatly reduced. Because of the outstanding advantages of pulse bag filter, it is more and more widely used. Pulse dedusting gas has many forms, such as reverse injection, forward injection, opposite injection, rotary injection, etc. Low pressure injection occurs when the blowing source pressure is lower than 0.25MPa; High pressure injection occurs when the blowing source pressure is higher than 0.5MPa.

The dust removal mechanism of bag filter is very simple. It is the same as the dust removal mechanism of mask. The price of industrial dust treatment is realized through the mechanical interception of fly ash particles in flue gas by filter materials. However, in addition, the first received fly ash particles also form a stable and dense ash layer (generally called filter cake or filter bed) on the surface of the filter material, which also plays a good role in filtration, especially for the dust collector with woven cloth as filter bag, which plays a major role in filtration. Filter element. The filter element can be woven (or) into filter material from cotton wool fiber, glass fiber or various chemical fibers, and then sewed into a vertically suspended filter bag. Different filter materials should be selected for different occasions. The dust collected on the filter bag deforms the bag and removes the dust through periodic mechanical shaking, filtered flue gas back blowing or pulse back blowing of compressed air.
