Venturi cyclone dust extractor

Abstract

The invention relates to a venturi tube cyclone dust collector, which is characterized by comprising a venturi tube and a cyclone sedimentation tower, wherein outlet gas of the venturi tube tangentially enters a cyclone area on the lower part of the cyclone sedimentation tower through an air inlet pipe of the cyclone sedimentation tower; the venturi tube consists of a contraction section, a throat section and a diffusion section; the side wall of the throat section is provided with a plurality of through holes, and the outer side of the through hole are connected with a pressure water supply pipe; a port of the diffusion section forms an air outlet of the venturi tube; a port of the contraction section forms an air inlet of the venturi tube; the lower part of the cyclone sedimentation tower is a cyclone area, the upper part is a sedimentation and dehydration area, and the middle part is provided with an annular clapboard; and the upper part of the sedimentation and dehydration area is provided with a plurality of gas-liquid separating layers. The venturi tube cyclone dust collector has the advantages of small investment, high dust removing efficiency, comparatively longer service life, small water consumption and low running cost, and can be mainly applied to the dust removal of high density flue gas and industrial dust in various industrial furnaces.

Description

technical field [0001] The invention relates to a Venturi tube cyclone dust collector, which can be mainly used for dust removal of high-concentration flue gas and industrial dust in various industrial furnaces. Background technique [0002] Industrial dust removal mainly includes dry dust removal and wet dust removal. Dry dust removal mainly includes bag dust removal technology and electrostatic dust removal technology. Wet dust removal mainly includes spray forest tower, foam tower, venturi tube, impact or self-excited dust removal technology, etc. etc. Various technologies have their own many advantages, but their shortcomings are still prominent. Among them, the main defects of dry dust removal are large investment, high operating cost, and large floor area, while wet dust removal is limited by the nature of dust. Under the condition of dust, you should pay attention to the dust removal efficiency, service life and water consumption. Contents of the invention [0003]...
