Description

Modular air purification sterilization apparatus

FIELD

The present invention relates to an air purification device, in particular a combined air purification sterilization apparatus. Room for electrical technology.

Background technique

Because syndrome, indoor air conditioning disease, organic pollution and other urban buildings and interior decoration of modern living environment caused by the direct impact on people's health and safety. Central air conditioning system is not due to regular cleaning and disinfection, their internal systems at the breeding ground for bacteria and environmental pollution caused, has increasingly attracted attention. In particular the use of central air-conditioning system caused the problem of cross infection of communicable diseases much attention. The current main air purifier activated carbon adsorption technology, ozone purification technology, high voltage negative electrostatic dust removal technology and techniques. The activated carbon adsorption technology can only store the adsorption of harmful substances, which can not be removed or decomposed, simply transfer the pollution. Technology ozone sterilization, deodorization effect, but the low efficiency of removal of organic pollutants and ozone in itself harmful to humans and the environment. And high voltage negative electrostatic technology is a physical role in the process, to remove dust in the air, but the pollution chemical, biological and microbiological purification and the like can not be removed due to.

Photocatalysis is an emerging environmental purification technology. Nano-TiO2 photocatalyst oxidized or reduced can be effectively adsorbed on the surface of the harmful gas molecules, kill bacteria, virus inhibition, and can harmful organisms, bacteria and the like into harmless substances of water and carbon dioxide, and no secondary Pollution. Therefore, in recent years become for indoor air purification hotspot.

Literature search found that patented invention entitled: one kind of indoor air purification method and device patent application number: 03126563.4, which patent discloses a charcoal filter, an ultraviolet lamp and air purification means Nano TiO2 photocatalytic combination. However, due to the large central air-conditioning gas flow, a photocatalytic air purification rate tends to be lower, although the contaminants in the air can reach the concentration of indoor air quality standards through multiple cycles, but not an effective solution due to the use of central air-conditioning system the infectious disease caused by cross-contamination issues. Meanwhile, use of activated carbon adsorption can not remove harmful gases, will eventually result in secondary pollution. On the other hand, the photocatalytic ultraviolet light source can be used to generate ozone, although ozone sterilization function, but also a coupling effect with the photocatalyst, significantly improved photocatalytic activity. However, if not properly controlled, they tend to pollute the environment and cause harm to human health.

By the above synergistic effect, a large amount of a high oxidative capacity · OH, thereby effectively removing organic pollutants and kill bacteria. By a chemical reaction can be schematically represented by the following equation: M representative of air (1) (2) (3) (4) (5) (6) (7) (8) (9) (9) of the organic . TiO2 is formed in the UV irradiation of electron - hole pairs, since ozone has a strong electrophilic properties, with the result that the composite probability of electrons and holes degradation, in order to achieve degradation of organic compounds. Further, after the electron capture ozone, and hydrogen ions generated in conjunction with highly active hydroxyl radical, in order to better degradation of organic matter in the air.
