Gas box-type bag-type dust collector integrating high-efficiency cyclone dust removal

Abstract

A gas box-type bag-type dust collector integrating high-efficiency cyclone dust removal is provided. Cyclones in the dust collector are arranged in a first-level gravity sedimentation chamber, and the central axis of each cyclone is in a vertical-state arrangement; a dust-containing gas inlet of each cyclone is located in the first-level gravity sedimentation chamber, and the center line of each dust-containing gas inlet is parallel to an upper tube sheet of the cyclones; the center line of a separated gas outlet of the upper end of each cyclone is coincident with the central axis of each cyclone; the separated gas outlet of the upper end of each cyclone and a dedusting port of the lower end of each cyclone are both communicated with a second-level gravity sedimentation chamber. By improving a structure of a gravity cyclone dust collector, the device described in the invention changes the structure of the cyclones and allows the dust-containing gas inlets of the cyclones to be parallel to the upper tube sheet of the cyclones, in the case, the center line and the central axis of the dust-containing gas inlet of each cyclone form an included angle which is an acute angle, a screw pitch of dust in the cyclones is small, the friction is mall, and the individual working efficiency of the mounted cyclones is improved with the connection way.

Description

technical field [0001] The invention relates to an electric dust removal device with a cyclone tube, in particular to an air box bag type dust collector with high-efficiency cyclone dust removal. Background technique [0002] At present, the dust collectors on the market are relatively mature technologies, mainly including cyclone dust removal, gravity dust removal, bag dust collection, electric dust removal, etc. However, there are not many equipment based on gravity sedimentation, cyclone dust removal and bag dust removal. Moreover, most of the devices are complex in structure and small in handling air volume, so there is an urgent need to provide a PPF air box bag type dust collector with good separation effect and low energy consumption, which integrates high-efficiency cyclone collection. At present, the dust collectors on the market are relatively mature technologies, mainly including cyclone dust removal, gravity dust removal, bag dust collection, electric dust remova...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the technical problems of poor working effect of the cyclone and easy entry of outside air into the dust collector, the present invention provides an air box bag type dust collector with high-efficiency cyclone dust removal. The device described in the invention improves the gravity cyclone dust removal device The structure of the cyclone is changed so that the dusty gas inlet of the cyclone is parallel to the upper flower plate of the cyclone. In this case, the angle between the center line of the dusty gas inlet of the cyclone and the central axis is an acute angle. The internal dust pitch is small and the friction is small. This connection method improves the individual working efficiency of the installed cyclone, thereby improving the overall dust removal efficiency.
