Air purification equipment (also known as “air cleaning equipment”, air freshener) refers to products that can filter or kill air pollutants and effectively improve air cleanliness, mainly domestic and commercial air purification equipment that removes indoor air pollution.
1. Low temperature asymmetric plasma. The low-temperature asymmetric plasma module forms an asymmetric plasma electric field through high-voltage and high-frequency pulse discharge, which makes a large number of plasmas in the air collide step by step. Generates an electrochemical reaction to rapidly degrade toxic and harmful gases and live viruses and bacteria, so as to efficiently kill viruses, sterilize, remove odors, eliminate smoke, and remove dust, and produce no toxic substances. It is known as the most environmental and health science in the 21st century. High-tech worth looking forward to. It can coexist with human and machine, no need to leave at the same time for purification; energy saving and consumption reduction, which can save 80% of electricity compared with the same period of last year; With fast virus killing, super purification ability, efficient odor elimination, static elimination function, increase oxygen content, etc.
2. Chemical preparations. The main products are air fresheners (car perfumes). Their products are inexpensive, but they can only mask some odors, and complex chemical reactions occur under the action of sunlight, becoming new pollution in the car, and it is impossible to eliminate harmful gases.
3. Chemical decomposition. The main working principle is the ionizer ozone generator. Ozone has a strong oxidizing power and is one of the strongest known oxidants. Ozone is the most widely used in sewage treatment, and its principle is the strong oxidizing property of ozone. After ozone decomposes, it decomposes into oxygen. It is cheap and has more functions than fresheners. It can increase the number of negative ions in the air and reduce solid dust in the air. It has a bactericidal effect but has little effect on the decomposition of harmful gases such as formaldehyde. The ozone generator produces a large amount of high-concentration ozone, which may kill human white blood cells at the same time as killing some virus bacteria. It may cause canceration. Negative ions are easy to adsorb dust and stick to the ceiling of the inner wall of the compartment, causing the interior compartment to be particularly shallow The color car will gradually turn gray-black.
4. Adsorption and volatilization. Chinese herbal medicine-based purifiers are inexpensive and have certain bacteriostatic functions, but Chinese herbal medicines basically do not purify in the solid state. The purifiers use only a small amount of Chinese herbal medicine ingredients. When they are saturated, they can not only sterilize but also become bacteria The reproduction body, the replacement filter element involves the difficulty of harmless treatment.
5. Adsorption. Activated carbon filter can absorb certain bacteria and dust and harmful gases in a short time, and it is inexpensive. It can filter certain bacteria and dust. It has an adsorption function, but has no selective adsorption. The adsorption rate for water is 45%, generally one month. After reaching saturation, it needs to be replaced. It cannot be recycled. After reaching saturation, it is not only unable to sterilize but also easily becomes a bacterial multiplication body. Replacement of the filter element also involves difficulties in harmless handling.
6. Multi-layer filtration. It is mainly a composite purifier with good filtering effect, which can obviously reduce the solid dust in the air, but the price is high, and its filter device requires replacement after a period of use, which cannot be regenerated, and has basically no effect on harmful gases. There are many consumables and high use cost. Replacement of the filter element involves difficulties in harmless handling.
7. Catalysis and decomposition. It is mainly a photocatalyst purifier, which can decompose some harmful gases, and the price is relatively low, but the photocatalyst is still in the experimental stage and the technology is not yet mature. The photocatalyst must rely on the irradiation of ultraviolet rays in sunlight to have an effect. The use of ultraviolet lamps is easy to damage and is frequently replaced. Ultraviolet rays are harmful to human body and plastic.
8. Filter adsorption. The hydrophobic crystalline silica molecular sieve is mainly used as a filter medium. The effect is obvious. It can completely remove a variety of harmful gases such as benzene, xylene, chloroform, etc. It does not adsorb water and air, and can effectively adsorb a variety of harmful gases. The adsorption capacity is large, and it can be used for one and a half years after regeneration. The filter material can be desorbed and reused in a simple way without generating new sources of pollution. The life of the material is up to ten years, so the maintenance cost is extremely low, and it has little effect on reducing solid dust in the air, which is higher than the one-time cost of other products.
9. NICOLER sterilization technology NICOLER is derived from Greek and originally meant “victorious people”. It now refers to the simultaneous operation of man and machine in the same field. A disinfection method: for air disinfection, people do not need to leave the disinfection place. This kind of disinfection method is called “dynamic disinfection”; it is also a “NICOLER sterilization technology” because it is a successful practice for humans to defeat natural organisms through science and technology. It can kill more than 300 kinds of gaseous pollutants in the decomposition room, such as formaldehyde, tritium, ammonia, benzene and other radiators, inhalable particles and various bacteria and viruses. Eliminate all kinds of strange odors caused by decoration and airborne dust, including cigarette smoke. No harm to human body.
10.Negative ion purification The working principle of removing indoor particulate pollutants is similar. They are all settled by charging particles in the air and agglomerating to form larger particles. However, the particles are not actually removed, but only adhere to the nearby surface, which is likely to cause dust again. .
Air purification equipment can filter airborne particles, bacteria, viruses, fungal spores, pollen, asbestos, radon decay products and other pollutants.
1. It can be put into use after interior decoration. Through comprehensive treatment of indoor walls, ceilings, carpets, curtains, sofas and storage cabinets and other pollution sources, organic pollutants such as formaldehyde and benzene can be effectively decomposed.
2. Improve indoor air quality. Purification products have the characteristics of deodorization, mildew resistance, antibacterial, and long-lasting air purification, which can purify the air, remove odors, prevent germ infection, effectively solve indoor air pollution, and eliminate adverse reactions that affect people’s mood due to indoor air pollution. .
3. Reduce daily tediousness. Due to the deterioration of indoor air quality, frequent use of fresh air products, fragrances, disinfectants, etc. not only increases daily expenditure costs but also causes secondary pollution.
According to the application field, it can be divided into: household air purification equipment, vehicle air purification equipment (also known as automotive air purification equipment), medical air purification equipment, industrial air purification equipment and engineering air purification equipment.
