Pulse bag type dust collector device

Abstract

The invention discloses a pulse bag type dust collector device. The pulse bag type dust collector device comprises an upper box body, a middle box body, a lower box body, an ash bucket, a dust collection mechanism and an ash cleaning mechanism, wherein a pulse controller of the ash cleaning mechanism is connected with a micro-differential pressure controller and a pulse valve; an outlet of the pulse valve is connected with a blowing pipe; the blowing pipe is communicated with an inner cavity of a filter bag through a venturi tube; an air inlet channel of the pulse valve is provided with an air packet structure; an air inlet pipeline of the air packet structure is provided with an air-water separator; the air-water separator can be used for improving the quality of compressed air and effectively preventing a phenomenon that water steam enters the cavity of the filter bag to influence the dust collection effect of the filter bag. A connection manner of the filter bag adopts a self-locking device and the filter bag is convenient to mount and replace; the service life of the filter bag can be effectively prolonged. Furthermore, an access door and a star-shaped ash unloading valve are tightly compacted and sealed by asbestos gaskets, so that the sealing performance of a dust collector is improved and the leakage is avoided. The pulse bag type dust collector device is simple in structure, high in dust collection efficiency and practical and flexible; an ash cleaning process can be automatically realized and the operation is stable.

Description

Technical field [0001] The invention relates to the field of industrial flue gas dust collector devices, in particular to a pulse bag type dust collector device. Background technique [0002] At present, the pulse bag filter is a kind of high-efficiency purification equipment widely used at home and abroad. It is a dry dust removal equipment that uses organic fibers or inorganic fiber woven fabrics to make filter materials to filter out solid particles in dust-containing gases. During the dust removal process of the pulse bag filter, a layer of dust will accumulate on the surface of the filter material. This layer of dust is called the primary layer. In the subsequent dust removal process, the primary layer becomes the main filter layer, which can effectively improve the dust removal efficiency. With the continuous accumulation of dust on the surface of the filter material, the resistance of the dust collector increases. When the pressure difference between the two sides of the f...

AI Technical Summary

Problems solved by technology

As the dust continues to accumulate on the surface of the filter material, the resistance of the dust collector will increase. When the pressure difference on both sides of the filter material is very large, some tiny dust particles that have attached to the filter material will be squeezed away and the first layer will be destroyed. , leading to a decrease in the efficiency of the dust collector

In addition, the high resistance of the dust collector will significantly reduce the air volume of the dust removal system, which will further lead to a decline in the efficiency of the dust collector.

Therefore, after the resistance of the dust collector reaches a certain value, the dust needs to be cleaned in time, but the first layer should not be damaged during the dust cleaning process, so as to avoid the decline of the dust removal efficiency.
