Cyclone dust removal device with double conical cylinders

Abstract

A cyclone dust removal device with double conical cylinders comprises a cyclone dust remover, a rotary bearing, the movable conical cylinder and the like. A draught fan feeds dusty gas into an air channel box, the dusty gas enters the cyclone dust remover through an air inlet of the cyclone dust remover and forms an outer cyclone flow, when the dusty gas rotates to the movable conical cylinder, dust grains penetrate through thin and long through grooves of the movable conical cylinder through centrifugal force, enter an interlayer formed by the two conical cylinders, descend along the inner wall of the fixed conical cylinder and is collected in a dust hopper, dustless gas spirally ascends (internal rotary flow) along the axis of the conical cylinders and flows out of an air outlet, and gas and the dust grains are separated. The dust grains enter the interlayer, the rebounding dust grains colliding with the fixed conical cylinder are blocked by the rotating movable conical cylinder, the dust grains are prevented from returning a cyclone field, and thus fine dust grains, especially dust grains of PM2.5 or above harmful to the body health are efficiently captured at a low air speed. The device has the advantages of being simple, easy to manufacture, convenient to maintain, low in working noise and the like, and is suitable for families, shopping malls, offices and occasions where clean gas or gas and dust separation is needed in industrial production and the like.

Description

technical field [0001] The invention relates to a double-cone cyclone dust removal device, mainly relates to a cyclone dust removal air purification device, which can be used to separate tiny dust particles in gas. Background technique [0002] Since Morse's cyclone dust collector was patented and put into use in 1886, it has been widely used in industry. 12~25m / s) into the cylinder part of the cyclone dust collector, the airflow changes from linear motion to circular motion, and makes a top-down helical motion along the loop space between the inner and outer cylinders and the cone, forming an outer Swirl flow; the centrifugal force generated by the dust particles during the rotation of the airflow makes the dust particles fling to the wall of the device; the dust particles contact the wall and lose inertial force, fall along the wall under the action of gravity, separate from the gas, and finally enter through the bottom of the cone Inside the ash collection tube; when the...

AI Technical Summary

Problems solved by technology

Analysis and practice show that due to the limitations of the working principle of the cyclone dust collector, it can effectively handle dust particles above 5 microns, and adding post-stage filtering equipment or adding spiral grooves, water films or sprays on the rotatable cone can effectively Improve the efficiency of removing dust particles above 2.5 microns, but the post-stage filter maintenance is inconvenient, and the dust removal method of the active spiral cone does not use a liquid film, and its dust removal efficiency will decrease. High sealing requirements between other components
