Wet dense grid filter purifier

Abstract

Provided is a wet-type filter purifier with dense grids, comprising a tank body (1), a dense grid plate (3), a spray head (5), a flow meter (7), a liquid supply pump (8), a liquid collection tank (9) and a liquid remover (15). A filtering unit uses the dense gate plate (3) with vertically and densely arranged fibre filaments and having a certain thickness, and utilizes the spray washing function of the spray head (5), so as to improve the filtering efficiency and the airflow processing capacity, and avoid blockage in the filtering unit. The liquid collection tank (9) mounted below the tank body (1) of the wet-type filter purifier with dense grids comprises a sealing plate (13), a liquid injection port (10), a dredging port (12) and a filter screen (11). A turbid cleaning liquid containing aerosol particles, which flows down after cleaning the dense grid plate (3) and is removed from the liquid remover (15), flows back into the liquid collection tank (9) via a drain port (14) and is recycled after precipitation and filtration.

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
