Problems solved by technology

Therefore, there is a common phenomenon that air purifiers are effective when they are newly bought, but after a period of use, the purification effect declines.
However, the paper filter plate cannot be regenerated, and the activated carbon is also difficult to desorb and regenerate, so we have to spend money to replace the expensive accessories, which increases the cost of use

Embodiment Construction

[0009] Such as Figure 1 to Figure 2 As shown, the folded air purification filter plate is mainly composed of a metal groove 1, a bead 2, a polyurethane foam spacer 3 and a chemical fiber cloth 4; the metal groove 1 is provided with a bead 2 (see figure 1 ), the chemical fiber cloth 4 is provided with a polyurethane foam spacer strip 3, and the surfaces of both sides of the chemical fiber cloth 4 are coated with absorbent materials (see figure 2 ).

[0010] Process flow of the present invention:

[0011] Non-absorbent, non-mildew nylon or nylon chemical fiber cloth is used to eliminate the mildew problem of paper filter plates. The surface of the chemical fiber cloth is impregnated with a thin layer of absorbent material and hydrophobic material. Adsorption materials use silica sol 40-50% as dilution and binder, diatomite 30-25%, zeolite 30-25% as adsorption functional filler, and add a small amount of 1-2% hydrophobic material, coupling agent, etc. . These materials are...

Abstract

The invention provides a folding type air purification filtering plate.According to the technical scheme, press strips (2) are arranged in a metal groove (1), a chemical fiber cloth (4) is provided with polyurethane foam plastic isolation strips (3), and the surfaces of the two sides of the chemical fiber cloth (4) are coated with an adsorbing material; the adsorbing material takes 40%-50% of silica sol as a diluting and bonding agent and takes 25%-30% of kieselguhr and 25%-30% of zeolite as adsorbing functional packing, and 1%-2% of a hydrophobic material and a coupling agent are added; the polyurethane foam plastic isolation strips with the thickness of 2 mm and the width of 10 mm are oppositely stuck to the two sides of the chemical fiber cloth (4) every other 150 mm, and 4-mm gaps are formed among the folded cloth portions after the folding type air purification filtering plate is folded.The folding type air purification filtering plate has the advantages that the design is reasonable and practical, the whole plate is ventilated and unobstructed, and the functions of a filtering part and an adsorbing part of air purification equipment are achieved; in addition, the defect that a common paper filtering plate and activated carbon adsorption part cannot be repeatedly used is overcome, the service life is prolonged, and the manufacturing and using cost is lowered.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a folded air purification filter plate. Background technique [0002] Human settlements include residences, offices, public venues, cabins of trains, ships, and cars, etc. The issue of air purification has received increasing attention, and various types of air purifiers have emerged as the times require. Most of the air purifiers are equipped with filter plates folded from filter paper and activated carbon as the main adsorption material. The paper filter plate can effectively remove particulate matter such as PM10 and PM2.5, and the activated carbon adsorption material can effectively remove some harmful gases such as formaldehyde. However, the paper filter plate is not water-resistant. If it works in a humid environment for a long time, it will become moldy, and the particles that are stained during filtration will gradually block the micropores of the filter plate, ...
