Centrifugal smoke dust separation device

Abstract

The invention discloses a centrifugal smoke dust separation device, which comprises a motor, an impeller assembly, a dust filtering drum, an outer drum body and an ash storage hopper; wherein the outer cylinder body comprises an upper cavity and a lower cavity which are separated, the impeller assembly is located in the upper cavity of the outer cylinder body, the dust filtering rotary drum is located in the lower cavity of the outer cylinder body, and an axial channel for gas to enter the upper cavity from the dust filtering rotary drum is arranged between the upper cavity and the lower cavity; the motor is vertically installed on a top cover of the outer cylinder, and a rotating shaft of the motor is connected with the impeller assembly and the dust filtering rotating cylinder. An air inlet is formed in the side face of the bottom of a lower cavity of the outer barrel, an air outlet is formed in the side face of an upper cavity of the outer barrel, and the ash storage hopper is installed at the bottom of the lower cavity of the outer barrel. The dust filtering rotary drum is provided with a concentric circle structure formed by rolling a plurality of corrugated plates, the dust filtering rotary drum is provided with a plurality of vertical channels defined by the adjacent corrugated plates, and a baffling sleeve is arranged outside the bottom end of the dust filtering rotarydrum. Dry dust removal is achieved, and the efficiency is high.

Description

technical field [0001] The invention relates to a smoke and dust separation device, in particular to a centrifugal smoke and dust separation device. Background technique [0002] Dust is one of the important sources of pollution. In the production process of metallurgy, materials, environmental protection and other industries, there is a large amount of high-temperature and high-dust gas. The traditional dust removal method generally uses a bag filter or a multi-tube dust collector. The bag filter removes dust through bag filtration. It is mainly suitable for filtering dust with a particle size of 1 μm or more. The temperature of the bag cannot exceed 200 ° C, and the wear resistance is poor, the service life is short, and it needs to be replaced frequently. The multi-pipe dust collector removes dust through cyclone separation, and the dust removal efficiency is not high. It is suitable for separating dust with a particle size of more than 10 μm. When the amount of dust-lade...
