Embodiment 1

[0034] The comprehensive purification method for indoor volatile organic pollutants, formaldehyde, mites, avian influenza virus and atmospheric particulates provided by this embodiment firstly installs a polymer adsorption material indoors, and the polymer adsorption material absorbs and catalyzes the purification of indoor atmospheric particulates, and then uses Chlorine dioxide gas with a purity higher than 99.5% diffuses into the room. While oxidizing and purifying indoor organic pollutants, formaldehyde, mites and avian influenza virus, chlorine dioxide gas can also enter the interior of the polymer adsorption material, which is harmful to the polymer adsorption material. The adsorbed atmospheric particles are oxidized and purified and the polymer adsorption material is regenerated in situ. Through the combination of the adsorption catalytic purification of the polymer adsorption material and the oxidation and purification of chlorine dioxide gas, the organic pollutants, for...

Embodiment 2

[0038] The comprehensive purification equipment of the indoor volatile organic pollutants, formaldehyde, mites, avian influenza virus and atmospheric particles provided by this embodiment, such as figure 1 Shown in, comprise macromolecular material adsorption device and high-purity chlorine dioxide generation device, macromolecular material adsorption device comprises macromolecule adsorption chamber 10, and macromolecule adsorption chamber 10 is equipped with the macromolecule adsorption material that is used for adsorbing atmospheric particles, macromolecular material One side of the adsorption chamber 10 is provided with a fan 11, and the other side is provided with a polymer chamber diffuser 9. The indoor air enters the polymer adsorption chamber 10 through the fan 11 and is released by the polymer chamber diffuser 9 after being adsorbed and purified. The pure chlorine dioxide generating device includes an air compressor 8, a high-purity chlorine dioxide gas vaporizer 5, a ...

Embodiment 3

[0042] at 6m 3 The sealed environmental test chamber (made of stainless steel) is the test environment. Dust particles TSP are placed on the ground of the environmental test chamber; benzene, volatile organic pollutants, benzene, and formaldehyde are injected with syringes; flu virus.

[0043] The initial concentration of high-purity chlorine dioxide is as shown in table 1, and the equipment (the purification equipment in embodiment 2) is put into the environmental test chamber, adopts the gas distribution positive pressure technology, and the stable chlorine dioxide solution and dilute hydrochloric acid are mixed according to 1 The molar ratio of :4 is added in the high-purity chlorine dioxide gas vaporizer 5 for reaction, and the gasification generation purity is 100% high chlorine dioxide gas mixed with compressed air. After half an hour ClO 2 The concentration is 100mg / m 3 , after 1 hour of diffusion for ClO 2 The concentration is 150mg / m 3 , to evaluate the final con...

Abstract

The invention discloses a comprehensive purification method for indoor volatile organic contaminants, formaldehyde, mites, avian influenza viruses and atmospheric particulates. High polymer adsorbing materials are arranged indoors and adsorb and catalytically purify indoor atmospheric particulates. Chlorine dioxide gas with the purity higher than 99.5% is adopted to be diffused into a room, and can enter the high polymer adsorbing materials when oxidizing and purifying indoor volatile organic contaminants, formaldehyde, mites and avian influenza viruses so as to oxidize and purify atmospheric particulates adsorbed by the high polymer adsorbing materials and enable the high polymer adsorbing materials to regenerate in situ. By combining adsorption and catalytic purification performed through the high polymer adsorbing materials with oxidization and purification performed through chlorine dioxide gas, the various contaminants in indoor air are comprehensively processed. The invention further discloses a comprehensive purification device. The method and device can remove indoor volatile organic contaminants, formaldehyde, mites, avian influenza viruses and atmospheric particulates at the same time, and is good in effect, low in cost and safe.

Description

technical field [0001] The invention belongs to the technical field of indoor air purification, and in particular relates to a comprehensive treatment method for indoor volatile organic pollutants, formaldehyde, mites, avian influenza virus and atmospheric particles. Background technique [0002] Indoor air pollution comes from decoration pollution and daily life pollution. Formaldehyde, benzene, volatile organic pollutants (VOC) pollution, etc. cannot be eradicated mainly because a large number of artificially synthesized products such as wood-based panels, foam plastics, and Mixtures, etc., resulting in the continuous release of harmful substances, and the formation of a superimposed effect, even if the real environmental protection product materials are excessively used in a small indoor space, resulting in exceeding the standard. The pollution caused by atmospheric particulate matter in people's daily activities is even more inevitable. Some developed countries in Europ...
