Embodiment 1

[0033] The method for purifying air by using a partition wall system in this embodiment includes installing a partition wall system with an air purification function in a house.

[0034] like figure 1 As shown, the partition wall system with air purification function in this embodiment includes inner gypsum board 1 , keel 2 , insulation layer 3 , cavity 4 , ultraviolet lamp 5 , one-way breathing membrane 6 and outer gypsum board 7 .

[0035] The cavity 4 is arranged between the insulation layer 3 and the one-way breathing membrane 6, and is in fluid communication with the air outlet of the fresh air system of the house; the ultraviolet lamp 5 is arranged on the top of the cavity 4 ; The one-way breathing membrane 6 is set between the heat insulation layer 3 and the outer gypsum board 7 .

[0036] The surface near the keel of the inner layer gypsum board 1 is sprayed with an effective content of 2g / m 2 Formaldehyde-degradable TiO under UV light 2 .

[0037] The outer surfac...

Embodiment 2

[0042] The only difference between this embodiment and Embodiment 1 is that the partition wall system does not include a cavity, an ultraviolet lamp and a one-way breathing membrane.

[0043] The formaldehyde purification effect of the partition wall system of Example 1-2 is shown in the table below:

[0044] serial number 24h formaldehyde purification rate Example 1 90.3％ Example 2 77.0％

Abstract

The present invention discloses a method for purifying air by using a partition wall system. The method comprises: using a partition wall system having air purification function, wherein the partitionwall system comprises an inner layer gypsum plate, a keel, a thermal insulation layer, a one-way breathing film, a cavity, an ultraviolet lamp and an outer layer gypsum plate, the one-way breathing film is arranged between the thermal insulation layer and the outer layer gypsum plate, the cavity is arranged between the thermal insulation layer and the one-way breathing film, and forms fluid communication with the wind discharge port of a house, the ultraviolet lamp is arranged at the top portion of the cavity, the surfaces of the inner layer gypsum plate and the outer layer gypsum plate are coated with an ultraviolet light formaldehyde degradation material TiO2 photocatalytic material in a spray coating manner, and the outer layer gypsum plate further contains a formaldehyde adsorbing material. According to the present invention, with the method, formaldehyde and other harmful gases can be effectively removed from room so as to purify the indoor air.

Description

technical field [0001] The present application relates to, but is not limited to, a method of purifying air using a partition wall system. Background technique [0002] Indoor formaldehyde pollution mainly comes from furniture, wood-based panels, various adhesive coatings and synthetic textiles, etc. Indoor formaldehyde pollution affects people's health and has aroused great concern. The hazards of indoor formaldehyde to human health mainly include stimulating effect, toxic effect and carcinogenic effect. If effective measures are not taken, the volatilization of formaldehyde lasts for as long as 3-15 years, seriously affecting the quality of indoor environment where people live. Contents of the invention [0003] The following is an overview of the topics described in detail in this article. This summary is not intended to limit the scope of the claims. [0004] The present application provides a method for purifying air using a partition wall system. [0005] The me...
