Application of Ozone in Air

Application of Ozone in Air

The application of ozone in air is based on its strong oxidizing and disinfecting properties. Ozone is reduced to oxygen and water during the process of pollution control, disinfection and sterilization, so there is no residue in the environment. Ozone can decompose harmful substances, transform them into non-toxic by-products, and effectively avoid secondary pollution caused by residues. For the development of ozone products, it has been widely used in many fields and has achieved very good results.

The application of ozone in indoor air is achieved by sterilizing the ozone by directly mixing ozone with indoor air or directly putting ozone into the indoor air, utilizing the extremely strong oxidation of ozone. As the secondary ozone is directly released into the air, the entire indoor space and all the objects in the space are filled with ozone gas, because the scope of sterilization and sterilization is wide, and the workload is also much smaller than that of disinfecting water spraying and scrubbing because the application very convenient.

1.For hospital sterilization
Hospitals are places where patients gather. The occurrence and spread of viral bacteria are serious. In order to protect the patient’s health, recovery, and avoid cross-infection, the hospital has strict sterilization procedures and regulations. The current methods of sterilization in hospitals are: A. Use of ultraviolet light for space air sterilization; B. Use potassium permanganate, peracetic acid for soaking and burning, steaming, boiling, etc. to disinfect the medical device supplies; C using splashing water for large-scale.

UV sterilization is currently mainly used in operating rooms, sterile rooms and other important places, its drawbacks are slow sterilization, high cost, there are dead ends (shadows), ultraviolet radiation can cause harm to human skin, strict application requirements. Liquid soaking and burning, steaming, boiling are not suitable for air disinfection. Spilled Su Su will cause a special smell in the hospital. The use of ozone gas disinfection can customer service these deficiencies. At present, many hospitals have used ozone-based medical devices and articles to wash with high-concentration ozone water, which is also superior to drugs.

2. Sterilization in public places
Waiting (ship, aircraft) room, cinema, stock trading room, meeting room, banking room, hotel, dance hall, nightclub, etc., the flow of personnel is relatively large, in addition to the air is more turbid, the cross-infection of the virus to people’s health There are still great threats, mentioning hepatitis B virus, cold virus and so on, which make people unpredictable. Ozone has a large market in sterilization and disinfection in these public places.

3. Household sterilization
The body’s respiratory metabolism, bathroom odor overflow, interior decoration and decoration, brought a variety of air pollutants to the interior, seriously polluting the air environment. The popularity of air conditioners has increased the tightness of the home. In this way, on the one hand, the exchange of indoor and outdoor air is limited; on the other hand, as early as the creation of a cool winter and cool summer environment, bacteria are more easily referred to, especially in wet areas. In general, indoor air pollution is usually more serious than outdoor, and it is necessary to use sampling to clean the house.

4. Sterilization in special places
Ozone can not be ignored in some special places. For example, in military and some special cabins (eg: capsules, submersibles, tanks, ambulance cabins), the installation of high-efficiency ozone generators can purify turbid air in the cabins and eliminate odors. Bacteria disinfection.

5. Sterilization, disinfection, deodorization, and preservation of sterilizers and foodstuffs
What kinds of disinfection cabinets are currently available on the market are infrared type, ultraviolet type, and ozone type. The infrared type consumes a large amount of electricity and has a high usage fee; the UV type detachment has a sterilization effect in a place where the ultraviolet rays are irradiated, and the effect area is small, and the effect is poor; while the ozone type is sterilized by ozone gas diffused around the dishes. , Low power consumption, good sterilization effect, make up for the lack of infrared and ultraviolet disinfection cabinet.

In addition to the role of ozone sterilization, its strong oxidizing properties can quickly decompose organic or inorganic substances with odors and other odors, can oxidize the decomposition of fruits and vegetables metabolism exhaled ripening agent – ethylene gas C2H2, so it also It has the effect of eliminating odor and preventing aging. The use of ozone for the preservation of food, fruits, vegetables, etc. is a very popular matter in Europe, America, Japan, and other countries, and has penetrated into all aspects of production, storage, and transportation.

Precautions when using ozone:
1. The concentration of ozone in the air at the job site cannot exceed the national allowable standard (0.2mg/m3). Air disinfection with ozone must be carried out in a confined space where people are not present on the site; humans can enter at least 30 minutes after disinfection.
2. Oxidation of various items should be fully considered when disinfecting items.
