Embodiment 1

[0034] In the comprehensive purification method of indoor volatile organic pollutants, formaldehyde, mites, avian influenza virus and atmospheric particulate matter provided by this embodiment, firstly, a polymer adsorption material is installed indoors, and the polymer adsorption material adsorbs and catalyzes the purification of indoor atmospheric particulate matter, and then adopts 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 viruses, chlorine dioxide gas can also enter the interior of the polymer adsorption material. The adsorbed atmospheric particulate matter is oxidized and purified and the polymer adsorption material is regenerated in situ. Through the combination of the adsorption and catalytic purification of the polymer adsorption material and the oxidation purification of chlorine dioxide gas, the organic pollutants, formaldehyde, mites and ...

Embodiment 2

[0038] The comprehensive purification equipment for indoor volatile organic pollutants, formaldehyde, mites, avian influenza viruses and atmospheric particles provided in this embodiment, such as figure 1 As shown in the figure, it includes a polymer material adsorption device and a high-purity chlorine dioxide generating device. The polymer material adsorption device includes a polymer adsorption chamber 10. The polymer adsorption chamber 10 is equipped with a polymer adsorption material for adsorbing atmospheric particles. 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 chlorine dioxide liquid inlet 6 and a chlorine...

Embodiment 3

[0042] by 6m 3 The sealed environmental test chamber (made of stainless steel) is the test environment, and dust particles TSP are placed on the ground of the environmental test chamber; benzene, volatile organic pollutants, benzene, and formaldehyde are injected with a syringe; mites and chicken are placed on old clothes. flu virus.

[0043] The initial concentration of high-purity chlorine dioxide is shown in Table 1, and the equipment (the purification equipment in Example 2) is put into the environmental test chamber, and the gas distribution positive pressure technology is adopted. The molar ratio of : 4 is added to the high-purity chlorine dioxide gas gasifier 5 for reaction, and the gasification generates high-level chlorine dioxide gas with a purity of 100% and is mixed with compressed air. ClO after half an hour 2 Concentration is 100mg / m 3 , ClO after 1 h of diffusion 2 Concentration is 150mg / m 3 , Evaluate the final concentration of volatile organic pollutants,...

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 particulate matter. 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. Mixtures, etc., lead to the continuous release of harmful substances, and form a superposition effect, even the real environmental protection product materials, excessive use 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 Europe and the United States have an early understanding of the impact of gases released from building materials on indoor air and th...
