Dust removing device

Abstract

The invention provides a dust removing device, relating to the technical field of dust-containing gas dust removing equipment. The dust removing device comprises a cylindrical device body (1), wherein an inlet pipe bottom plate part (4) of a flue gas inlet pipe (3) of the dust removing device is of a structure in which a bottom plate outer side part (4) is higher than a bottom plate inner side part (6) connected with the device body (1); a lower barrel (2) comprises an upper conical barrel (7) and a lower conical barrel (8); and the device body (1) and the lower conical barrel (8) are communicated with an upper opening (9) of the upper conical barrel and a lower opening (10) of the upper conical barrel respectively. The dust removing device provided by the invention can realize a secondary separation effect; separated dust can be prevented from being carried by inner vortexes, so that the dust removing efficiency is improved; the flue gas inlet pipe adopts a special-shaped inlet structure so that the mutual interference between inlet gas and the inner vortexes is avoided; and gas flow working conditions in the dust removing device are effectively organized and the dust removing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of dust removal equipment for dusty gas, and more specifically relates to a dust removal device. Background technique [0002] In the field of dusty gas dust removal equipment, cyclone dust collectors have been widely used. However, the dust removal efficiency of the existing cyclone dust collector is about 85%, and it is difficult to enlarge it, because usually, the diameter of the cylinder of the cyclone dust collector increases, and the dust removal efficiency will decrease accordingly. This limits the application effect of the cyclone dust collector. On the one hand, it reduces the use efficiency, and on the other hand, it cannot meet the large-scale requirements of the dust collector in actual production. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dust removal device with a simple structure, which can satisfy the dust removal of larg...

However, the dust removal efficiency of the existing cyclone dust collector is about 85%, and it is difficult to enlarge it, because usually, the diameter of the cylinder of the cyclone dust collector increases, and the dust removal efficiency will also decrease.

This limits the applicable effect of the cyclone dust collector. On the one hand, it reduces the use efficiency, and on the other hand, it cannot meet the large-scale requirements of the dust collector in actual production.
