Vertical electrical dust collector integrating gravity and cyclone dust removal

Abstract

A vertical electrical dust collector integrating gravity and 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 collector with a cyclone tube, in particular to a vertical electric dust collector integrating gravity and cyclone dust removal. Background technique [0002] Cyclone dust removal is a dry gas-solid separation device that uses the centrifugal force generated by the rotating dust-laden gas to separate dust from the airflow. It has high efficiency in collecting and separating dust above 5~10um. It is characterized by simple structure, simple operation and maintenance, stable operation performance, and is not limited by the concentration and temperature of dust-containing gas. [0003] The electrostatic precipitator is a device that uses static electricity to attract fine dust particles to purify the gas to achieve the purpose of dust removal. It has a good removal effect on dust particles with a particle size below 5um. If the use conditions are suitable, its dust removal efficiency can reach 99% or even hig...

Problems solved by technology

[0007] 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 a vertical electrostatic precipitator integrating gravity and cyclone dust removal. The device described in the invention is improved by gravity cyclone dust removal The structure of the device changes the structure of the cyclone 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 dust pitch in the rotor is small, and the friction is small. This connection method improves the working efficiency of the installed cyclone, thereby improving the overall dust removal efficiency.
