Description

Air purification cleaning system and method thereof

The invention relates to the technical field of air purification, in particular to an air purification cleaning system and a method thereof.

With the development of modern industry, air pollution is becoming more and more serious, and the common sources of pollution in general life include:

1. PM2.5 suspended particles (Particulate matter with size smaller than 2.5m), mainly from the surface and engineering raised dust, incense, power plants, containing oxides, minerals and other ingredients, indoor standard value: daily average 35g / M3, annual average value of 15g/m3. Sea salt is also the second largest source of suspended particles, and its composition is similar to that of seawater. In addition, it can also be converted from sulfur and nitrogen oxides. This part is called derivatized fine aerosol. PM2.5 aerosols will directly enter the bronchial tubes when inhaled by the human body, which interferes with the gas exchange in the lungs and directly affects the lungs. Breathing function makes the body easy to be in anoxic state. In addition to causing diseases such as asthma, bronchitis and cardiovascular disease, excessive inhalation may also cause pneumoconiosis and even lung cancer.

2. Formaldehyde is almost ubiquitous in the general home environment, and the indoor standard value should be <0.5ppm. Such as toenails, clothing, formaldehyde resin used in furniture, foamed urea formaldehyde resin for home insulation, etc., such as wood-based panels, adhesives, paints, carpets, chemical fiber fillers, etc. Toxic ingredients, gas and cigarettes will also release formaldehyde, the existence of air in the life of up to 3-15 years, the danger to the human body It lasts for a long time. High concentrations of formaldehyde can cause symptoms of discomfort in the eyes, nose, and throat, and formaldehyde has been identified by the World Health Organization as a carcinogenic and teratogenic substance.

3. CO2 carbon dioxide, although non-toxic, high concentration will cause human discomfort, long-term exposure to calcium will lead to osteoporosis, indoor standard value should be <1000ppm, outdoor about 300-400ppm. Mainly from human body exhalation, car emissions, garbage incineration, incense, gas stove burning, etc., serious areas such as: thermal power plants, cement manufacturing plants, temples, air-conditioned confined spaces, department stores, big domes, theaters, office buildings, cars , tour bus, basement parking lot, etc.

4. Total Volatile Organic Compound (TVOC), mainly from the factory, is more harmful to the residents around the factory and the workers in the factory. Including: Benzene, Carbontetrachloride, Chloroform, 1,2-Dichlorobenzene, 1,4-Dichlorobenzene (1, 4-Dichlorobenzene), Dichloromethane, Ethyl Benzene, Styrene, Tetrachloroethylene, Trichloroethylene, Toluene, and Xylene.
