Classification characteristics and maintenance of Air sterilizer

The ozone generator in the Air sterilizer is mainly made by electrolysis. Generally, large and medium-sized ozone generators have two types of oxygen source and air source, which directly electrolyze oxygen into ozone. The ozone generated by the ozone generator has an instantaneous oxidation effect at low concentration.

Removal of manganese, removal of sulfide, removal of phenol, removal of chlorine, removal of pesticide odor, and disinfection of petroleum products and components after washing; as an oxidant, used in the production of certain fragrance components, refining drugs, grease components, and fiber components; used as a catalyst It is used for quick-drying of ink and paint, combustion-supporting and brewing fermentation, various fiber pulp bleaching, decolorization of Quansheng detergent, deodorization and sterilization of fur processed parts, etc.; it has disinfection and deodorization effects in hospital wastewater treatment. In terms of wastewater treatment, it can remove phenol, sulfur, cyanide oil, phosphorus, aromatic hydrocarbons and metal ions such as iron and manganese.

The classification features are diverse because of its diverse principles and types. But the primary type is still plasma air machine and ultraviolet Air sterilizer. As an internationally advanced plasma Air sterilizer, compared with the traditional ultraviolet circulating Air sterilizer, it has the following advantages: Efficient sterilization: The plasma sterilization effect is good, and the effect time is short, which is far less than high-intensity ultraviolet rays. , Environmental protection: Plasma sterilization and disinfection work continuously without ultraviolet rays and ozone, avoiding secondary pollution of the environment.

Efficient degradability: Plasma disinfection machine can also degrade harmful and toxic gases in the air when disinfecting the air. According to the test report of the Center for Disease Control and Prevention of China, the degradation rate within 24 hours: 91% of formaldehyde and 93% of benzene It is divided into 78% for ammonia and 96% for xylene. Together, it can efficiently remove pollutants such as flue gas and smoke odor. Low energy consumption: The power of the plasma Air sterilizer is 1/3 of that of the ultraviolet disinfection machine, which is very energy-saving. For a room of 150 square meters, plasma machine 150W, ultraviolet machine 450W or more, saving more than 1,000 yuan a year in electricity costs.

There are many types of Air sterilizers, and there are many principles. Some use ozone technology, some use ultraviolet lamps, some use filters, some use photocatalysis, and so on. Primary efficiency filtration, medium and high efficiency filtration, electrostatic adsorption filtration: Effectively remove particles and dust in the air. The photocatalyst mesh antibacterial mesh assists in disinfection. Generally, nano-level photocatalyst materials (mainly titanium dioxide) are used to cooperate with the illumination of a violet lamp to generate positively charged “holes” and negatively charged negative oxygen ions on the surface of the titanium dioxide.

The “cavity” combines with the water vapor in the air to produce a strongly alkaline “hydroxide radical”, which differentiates the formaldehyde and benzene in the air into harmless water and carbon dioxide. Negative oxygen ions combine with oxygen in the air to form “reactive oxygen”, which can differentiate bacterial cell membranes and oxidize virus proteins, achieving the purpose of sterilization, detoxification and differentiation of harmful gases from the surface.

Ultraviolet light completes the inactivation effect of bacteria in the air. The closer the ultraviolet lamp tube is to the object to be disinfected, the more bacteria will be killed and faster. On the scale of ultraviolet radiation, it can ensure that the death rate of bacteria is 100%, and no bacteria escape. The principle of sterilization is to irradiate bacteria, viruses and other microorganisms with ultraviolet rays to damage the structure of DNA (deoxyribonucleic acid) in the body, causing it to die immediately or lose its ability to reproduce.

Quartz UV lamps have advantages, so how to distinguish between serious and fake? Different wavelengths of ultraviolet light have different sterilization capabilities. Only short-wave ultraviolet (200-300nm) can kill bacteria. Among them, the 250-270nm scale has the strongest sterilization ability. The cost and function of ultraviolet lamps made of different materials are different. Really high-intensity, long-life ultraviolet lamps must be made of quartz glass. This kind of lamp is also called quartz sterilization lamp. It is divided into two types: high-ozone type and low-ozone type. Generally, high-ozone type is used in disinfection cabinets. It is also a distinctive feature of quartz UV lamps compared to other UV lamps.
