Haze collection unit based on corona discharge and haze-removal apparatus

Abstract

The invention discloses a haze collection unit based on corona discharge and a haze-removal apparatus. The haze collection unit comprises a main fixed frame, bias pole plates, collection pole plates, an annular coating layer, an upper driving shaft, a lower driving shaft, a transmission band, a driving mechanism, and an infiltrate mechanism; the haze particles with negative electricity is introduced into a space between the bias pole plate and the collection pole plate, the haze particles with the negative electricity move to the collection pole plate, and are absorbed to the pole plate coating layer coating the outer surface of the pole plate, the driving mechanism drives the upper driving shaft and the lower driving shaft to move the annular coating layer, so that the whole annular coating layer is in an infiltrate state, so that the haze particles with the negative electricity are attached. The method uses a wet-type dynamic dust collecting and water circulation cleaning scheme to increase the collection efficiency of the haze particles, and reduces the generation of secondary entrainment phenomenon and back corona phenomenon; the field intensity between the collection pole plate and the bias pole plate is increased by increasing the quantity of the collection pole plate and the bias pole plates, and the volume of the haze collection unit is reduced.

Description

technical field [0001] The invention belongs to the field of high voltage and electrostatic dust collection, and more specifically relates to a haze collection unit and a haze removal device based on corona discharge. Background technique [0002] Electrostatic dust collection technology is widely used in industrial dust removal and air purification of large indoor spaces due to its low pressure drop, low operation and maintenance costs and relatively high dust collection efficiency. At present, most electrostatic dust collection devices adopt the operation scheme of dry dust collection + vibrating cleaning, that is, the smog particles that enter the channel and complete the charging are directly deflected to the exposed dust collecting plate under the action of the deflecting electric field, and are passed through the vibration. The beating mechanism falls into the dust hopper below the pole plate and is discharged. Once the charged smog particles touch the plate, partial ...

Problems solved by technology

[0003] For the above defects of the prior art, the present invention provides a haze collection unit and haze removal device based on corona discharge, the purpose of which is to use electrostatic dust collection technology to achieve indoor air purification, thereby solving the problem of traditional electrostatic dust collectors. Due to the use of dry dust collection, the collection efficiency of fine particles is low, which is prone to technical problems such as secondary entrainment and back corona, and solves the technical problems of large volume and secondary air pollution.
