Embodiment 1

[0017] Embodiment 1, a preparation method of a solid air purification material, comprising the following steps: weighing 52 g of inorganic porous material activated alumina, 18 g of nano-titanium dioxide, and luminescent powder (the luminescent powder in this embodiment was purchased from Liche, Wuqiang County, Hebei Province Fluorescent powder factory) 4g, sodium chlorite powder 24g, sodium lignosulfonate 2g, polyethylene glycol 1200, polyvinyl alcohol, the luminescent powder is used polyethylene glycol 1200 aqueous solution (concentration of polyethylene glycol 1200 is 0.05 wt%~0.1wt%) 500ml into a paste, uniformly dispersed after stirring, nano-titanium dioxide, sodium lignosulfonate and luminescent powder adjusted into a paste, and then sprayed onto the inorganic porous material carrier, while spraying Stir the inorganic material, evenly adsorb and mix to form a pre-product;

[0018] Sodium chlorite powder is mixed with the above-mentioned pre-products and put into a granu...

Embodiment 2

[0020] Embodiment 2, another object of the present invention is to provide an application of the solid air purification material prepared by the above method, and the solid air purification material is applied in the fresh air system.

[0021] The solid air purification material prepared in Example 1 of the present invention is applied in the fresh air system, and the chlorine dioxide content detection test (ultraviolet-visible spectrophotometry), bactericidal test and formaldehyde degradation performance test are carried out. The bactericidal test adopts GB21551.3- In 2010, special requirements for antibacterial, sterilizing, and purification air purifiers for household and similar electrical appliances were tested. The formaldehyde degradation performance test was carried out using GB / T18801 air purifiers, and according to the "Disinfection Technical Specifications" (2008), The experimental results are shown in Table 1-3:

[0022] Table 1 chlorine dioxide concentration detec...

Abstract

The invention provides a preparation method and application of a solid air purification material, and the method comprises the following steps: weighing a certain amount of an inorganic porous material, nano titanium dioxide, luminescent powder, sodium chlorite powder, polyethylene glycol 1200 and polyvinyl alcohol, the inorganic porous material is activated alumina or activated zeolite, the preparation method comprises the following steps: blending the luminescent powder into paste by using the polyethylene glycol 1200 and the water, stirring, carrying out ultrasonic uniform dispersion, uniformly mixing the nano titanium dioxide, sodium lignin sulfonate and the blended pasty luminescent powder, spraying onto an inorganic porous material carrier, stirring an inorganic material while spraying, and uniformly adsorbing and mixing to form a pre-product, thereby obtaining the product. The process is simple, the raw materials are easy to obtain, and the prepared product can effectively remove VOCs.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a preparation method of a solid air purification material. Background technique [0002] At present, the effective purification of air in the market generally adopts the adsorption method. The adsorption method is a method of removing pollutants by using the physical adsorption, chemical adsorption, catalytic oxidation and reduction of activated carbon, bamboo charcoal, molecular sieve, minerals and other materials. Zeolite is well known in the prior art, and it is a crystalline aluminosilicate Salt, as a porous inorganic material, has abundant micropores, molecular screening properties, and good thermal and hydrothermal stability, and is widely used in catalytic and adsorption separation processes. But the effect of absorbing and decomposing formaldehyde and various pathogenic bacteria sources in the air is not ideal. [0003] Chlorine dioxide is a non-toxic, harmless...
