Industrial air purification system

Abstract

The invention discloses an industrial air purification system. Aiming at the main physicochemical and size distribution properties of promiscuously discharged smoke dust produced in an industrial production process, a blind window, an efficient separation trough plate and an static electricity integrated three-stage particle capture method is adopted, a spraying and liquid film flushing two-stage particle ash removal process is disclosed, finally, the efficient capture of promiscuous smoke dust in the industrial production process is realized, and a working environment is thoroughly improved; and based on ''blind window, efficient separation trough plate and static electricity integrated three-stage particle capture'' and ''spraying and liquid film flushing two-stage particle ash removal, ''filtration concentration and filter pressing particle raw material recycle'' is further adopted, so that the resource utilization of smoke dust particles and cyclic utilization of industrial water are realized.

Description

technical field [0001] The invention belongs to the field of air pollutant control, specifically relates to the technical field of dust purification and dust removal generated in unorganized discharge places, and in particular relates to an industrial air purification system. Background technique [0002] The productive dust formed in the process of industrial production (metallurgy, mining, machinery manufacturing, refractory material processing, textile, packaging, etc.) can float in the air of the workplace for a long time, which is an important factor that pollutes the working environment and damages the health of workers. Occupational hazards can cause a variety of occupational lung diseases including pneumoconiosis. During the "Thirteenth Five-Year Plan" period, the Ministry of Environmental Protection decided to revise the pollutant discharge standards for iron and steel, building materials, non-ferrous metals, thermal power, boilers, coking and other industries and t...

AI Technical Summary

Problems solved by technology

However, during the use of the electrostatic precipitator and the use of mechanical vibration to clean the dust, the particles are prone to secondary back-mixing and discharge into the atmosphere, resulting in the discharge of particles at the equipment outlet exceeding the standard, or although a small number of wet cleaning methods are used, there are equipment interruptions during the cleaning process Operation and flushing waste liquid discharge problems. At the same time, most of the equipment adopts steel structural parts, which are heavy, bulky, and occupy a large area. The efficiency of electrostatic dust removal needs to be further improved.

[0005] In addition, the dust generated in the production process of steel and metallurgical industries, such as the dust generated in the process of raw material storage and transportation, raw material crushing, batching and mixing, crushing and screening in the production of pellets, the analysis results show that the concentration of dust in the atmosphere can be reduced instantaneously. As high as dozens of grams to several hundred grams per cubic meter, particle size distribution of 1 to 1000 microns, iron powder content as high as 90%, this part of dust is discharged into the atmosphere in an unorganized manner, which not only causes pollution, but also causes resource waste and cost loss. It can be recycled and has great potential for reducing consumption per ton of ore cost
