Description

High-efficient clear pulse bag dust collector ware
Technical Field
The invention relates to the technical field of dust collectors, in particular to a high-efficiency clean pulse bag-type dust collector.
Background
The pulse bag-type dust collector is an advanced high-efficiency bag-type dust collecting device and has the characteristics of high dust removing strength, high speed, short cycle period, small occupied area and the like. The working principle is that dust-containing gas enters the interior of the dust collector, coarse dust particles in the gas directly fall into the dust hopper due to the inertia effect, fine dust particles are upwards filtered along with the air flow, the dust is attached to the outer surface of the filter bag, and the purified gas is discharged into the atmosphere from the air outlet after penetrating through the filter bag. Along with the continuous progress of the filtering working condition, the dust attached to the outer surface of the filter bag is gradually increased, the resistance of the air flow passing through is also gradually increased, and the dust removal effect is poor. At this time, the filter bag needs to be cleaned to remove dust.
The mode that current deashing work adopted is the room blowback of following, high-speed air current through release compressed gas production passes the filter bag and can effectively get rid of filter bag surface impurity, when a filter bag by the back flush in-process, the dust impurity who breaks away from the filter bag surface still exists inside the dust remover and encircles around each filter bag, the dust impurity that flies at this moment still can adhere again at the surface of other filter bags, because the pulse deashing mode is that a plurality of filter bags wash one by one, therefore all filter bags can be because of the deashing process of other filter bags by the repeated "pollution", finally influence the inside deashing effect of dust remover.
