A cyclone pressurized dust removal device

Abstract

The invention belongs to the field of dust collection process devices, and particularly relates to a cyclone pressurization dust collection device comprising a first-stage dust collection barrel, a second-stage dust collection barrel, a third-stage dust collection barrel and a connection rod pressurization mechanism. The connection rod pressurization mechanism comprises a first-stage drive material throwing impeller, a spiral axial flow impeller, a circulation cyclone even distribution mechanism, a rotating shaft, a bearing, a stirring supporting shaft and a secondary drive material throwing impeller. The circulation cyclone even distribution mechanism is provided with air flow collection ports, air flow guide channels, air flow outlets and air flow mixing areas. According to the cyclone pressurization dust collection device, by conducting secondary pressurization inflow and secondary hydrocyclone separation on air flow subjected to separation and conducting rotary separation on circulating air again for multistage dust collection, dust collection is conducted on dust, brought away because the inflow speed exceeds the critical air inlet air flow speed, again while the processing amount of dust-containing air is increased, and therefore the dust collection effect is improved.

Description

technical field [0001] The invention belongs to the field of dust removal process equipment, and in particular relates to a cyclone pressurized dust removal device. Background technique [0002] The working process of the cyclone dust collector is that when the dusty gas enters the cyclone separator from the air inlet, the airflow changes from linear motion to circular motion. Most of the rotating air flow spirals downward from the cylinder along the wall; the dust-laden gas produces centrifugal action during the rotation process, and once the dust particles with a relative density higher than the gas contact the wall, they lose the radial inertial force However, relying on downward momentum and downward gravity, it falls along the wall and enters the ash collecting hopper. In the prior art, the cyclone dust collector has the defects of incomplete dust removal, high dust content in the air outlet, and small air volume for processing. The improvement of the dust collector ma...
