Rotational flow suction type dust haze charged dust removal device

Abstract

The invention discloses a rotational flow suction type dust haze charged dust removal device. The device comprises a dust capture assembly, a dust corona charge assembly and an electrostatic sprayingdust removal assembly; the dust capture assembly is used for generating a rotary suction air flow, and dust particles in the working area are captured through the rotary suction air flow; the dust corona charge assembly is used for charging the non-charged dust particles; and the electrostatic spraying dust removal assembly is used for carrying out dust removal purification on the air flow containing the charged dust particles. According to the device, suspended dispersed dust particles can be captured by the rotary suction air flow, the captured dust particles can generate corona charges, thecharged dust can be thoroughly cleaned through electrostatic spraying, the dust removal efficiency is effectively improved, and the sewage generated in the dust removal process can be collected, so that pollution to the environment caused by the sewage is avoided; and secondary dust raising can be avoided in the dust removal process, and the water utilization rate in the dust removal process is high, dust parameters can be automatically detected, the dust removal parameters can be automatically adjusted, fire prevention and fire control can be realized, and the safety of the working area canbe guaranteed.

Description

technical field [0001] The invention belongs to the technical field of dust prevention and control, and in particular relates to a swirl suction type dust mist charged dust removal device. Background technique [0002] During the processing of metal products, there are usually grinding, cutting, grinding and polishing processes, especially the cutting process will produce a large amount of metal dust, accompanied by sparks. If a large amount of metal dust is inhaled into the lungs, it will seriously endanger the body. It is not healthy, and the sparks generated when cutting metal products may also cause a fire. [0003] At present, the main dust removal methods for metal dust include mechanical dust removal, filter dust removal, electrostatic dust removal and wet dust removal. Mechanical dust removal is only suitable for large-sized dust particles; filter dust removal will cause a large pressure loss over time, requiring regular cleaning and replacement of filter materials,...

AI Technical Summary

Problems solved by technology

Mechanical dust removal is only suitable for large-sized dust particles; filter dust removal will cause a large pressure loss over time, requiring regular cleaning and replacement of filter materials, and the cost of dust removal is high; electrostatic dust removal is prone to back corona and secondary dust. , will lead to a decrease in dust removal efficiency; wet dust removal is only suitable for dealing with large-sized dust particles, and the water consumption is large
