Composite dedusting equipment

Abstract

The invention provides composite dedusting equipment. The composite dedusting equipment comprises housing; the internal part of the housing is divided into a dust collecting zone, a filter bag zone, and an electrostatic zone from the bottom to the top successively; a dust-containing gas inlet is arranged on the housing on one side of the dust collecting zone; a dust collecting outlet is arranged on the housing on the lower part of the dust collecting zone; a purified gas outlet is arranged on the upper part of the housing; the filter bag zone comprises a plurality of vertical filter bags; theupper part of each vertical filter bag is connected with a telescopic foldable pipe through series connection; the upper part of each telescopic foldable pipe is provided with a Venturi tube; the Venturi tubes are communicated with a blowing pipe; the blowing pipe is controlled by a pulse control assembly for pulse blowing. The composite dedusting equipment is capable of improving flue gas dedusting effect, and possesses relatively removing capacity on ultrafine floating dust.

Description

Technical field [0001] The invention belongs to the technical field of flue gas dust removal, and specifically relates to a composite dust removal equipment integrating static electricity and filter bags. Background technique [0002] The dry dust removal process of flue gas is mainly based on two processes: filter bag dust removal and electrostatic dust removal. Filter bag dust removal is generally to filter dust-containing flue gas through a filter bag to discharge the net flue gas, and the dust-containing particles are blocked by the filter bag. It is placed on the filter bag and collected by regular blowing off. The electrostatic dust removal uses the static electricity of the electrode plate to attract the dust in the flue gas, so as to achieve the purpose of dust removal. The two dust removal processes have their own advantages and disadvantages. In order to achieve the need for dust removal effects, there is currently a composite dust removal equipment that combines the tw...

AI Technical Summary

Problems solved by technology

However, most of the existing composite dust removal equipment adopts the combined method of electrostatic dust removal first and filter bag dust removal later.

However, due to the large size distribution of the particles in the flue gas, the load on the electrode plate is relatively large when it first passes through the static area. Very limited improvement
