Description

Pulse bag type dust collector

Technical Field

The utility model belongs to the field of dust treatment equipment, and particularly relates to a pulse bag type dust collector.

Background

In industrial production, a large amount of industrial dust is often generated, and according to regulations of national environmental departments and the like, the generated industrial dust needs to be treated for harmlessness and the like, and in this case, various dust collectors are needed.

The bag house is more adaptable when the industrial dust to be handled is non-cementitious, non-fibrous. The bag type dust collector filters through a filter bag processed by cotton, wool, artificial fiber and the like, mainly filters through a dust primary layer and a dust collecting layer formed on the surface of the filter bag, collects dust mainly through a gravity settling effect, a screening effect, an inertia collision effect and a diffusion effect, and finally forms a dust layer attached to the surface of the filter bag, namely the primary layer. Along with the accumulation of dust in the filter bag, the pressure difference between two sides of the filter bag is increased, the gap inside the dust layer is reduced, and the flow speed of air passing through the filter bag holes is increased. Thus, dust particles adhered between the gaps can be taken away, and the dust removal efficiency is reduced. In addition, the resistance is too large, so that the filter bag is easy to damage, and the air quantity of the ventilation system is reduced. Therefore, after the dust remover operates for a period of time, the dust is removed in time, and the initial layer cannot be damaged during dust removal, so that the dust efficiency is prevented from being reduced.

The filter bags of the existing pulse bag type dust collector are vertically arranged in rows, and during dust collection, a small amount of dust cannot be captured in the upward operation process of dust-containing gas, so that the problem of incomplete dust collection occurs.
