Wet-type dense grid filter purifier

Abstract

The invention discloses a wet-type dense grid filter purifier which comprises a box, a dense grid plate, an atomizing spray head, a flow meter, a liquid supply pump, a liquid collection box and a liquid removal device. A filtering unit adopts the dense grid plate on which fibers are vertically and densely arranged and which has certain thickness, and a spray washing effect of the atomizing spray head is utilized for improving the filtering efficiency and air treatment capacity and blocking the blockage of the filtering unit. The liquid collection box on the lower part of the box of the wet-type dense grid filter purifier comprises a sealing plate, a reflux inlet, a liquid injection port, a dredging opening and a filtering net, aerosol particle-containing turbid cleaning liquor flowing from the cleaned dense grid plate and dropping from the liquid removal device can flow back into the liquid collection box through a discharge opening and is recycled after precipitation and filtration, and the operations of dredging and replacing the cleaning liquor can be periodically performed according to the deposition conditions at the bottom of the liquid collection box. Moreover, the wet-type dense grid filter purifier can adopt cleaning solutions of different properties according to the properties of aerosol particles to be purified, and the wet filtering purification aim is achieved.

Description

technical field [0001] The invention belongs to wet filtering and purifying equipment, in particular to a wet dense grid filtering and purifying device. Background technique [0002] Along with human's daily life and production activities, it is inevitable to produce some harmful solid or liquid particles called aerosol particles. These particles escape into the air and will seriously pollute the working environment and living environment. The wet filter purifier is an aerosol particle purification equipment that combines the filtering effect of fiber filter material and the spray cleaning effect of cleaning liquid. [0003] Existing wet filter purifiers are generally divided into two types that use porous fibrous materials as the filter layer and those that use single-layer fiber grids as the filter layer. Due to the disordered arrangement of fibers in wet filter purifiers with porous fibrous materials, the cleaning of the solid aerosol particles filtered in the filter lay...

AI Technical Summary

Problems solved by technology

Due to the disordered arrangement of fibers in wet filter purifiers with porous fibrous materials, the cleaning of the solid aerosol particles filtered in the filter layer by the cleaning liquid is affected, resulting in frequent clogging and increased purification resistance; The wet filter purifier with a single-layer fiber grid as the filter layer, because the gap between the fiber filaments fluctuates when the wind passes through, the aerosol particles are easy to leak through, resulting in a decrease in the purification efficiency

[0004] The dense grid is a filter material made of vertically densely arranged fiber filaments of a certain diameter with a certain density and thickness. Combined with spray washing liquid, it can solve the problem of reduced service life and single fiber filter layer due to clogging of disorderly arranged fiber porous filter layers. The problem that the purification efficiency is reduced due to the large and small gap of the grid
