2. Air disinfection

(1) Ozone air disinfection equipment

The most important ones are often easily overlooked. As the air that accompanies life every moment, its importance is rarely mentioned. People also talk about air quality, but too much energy is devoted to aspects such as air pollution, environmental temperature regulation, and the addition of negative ions. The equally important disease infection control is often regarded as a matter of medical experts. It is generally taken seriously by all sectors of society. Today, the disinfection and sterilization of air in public places has become the focus of social attention.

Ozone has excellent sterilization, disinfection, purification of air and water quality. Ozone can oxidize many compounds and can be used for the disinfection of infection sources and air. It is the most powerful disinfectant among many disinfectants. Another outstanding feature is the formation of oxygen after decomposition, increasing the oxygen content in the disinfected space. In order to remove bacteria and viruses in the air and water and increase the oxygen content in the air, people can often open the doors and windows to make the room well ventilated. This may increase the oxygen content in the air, but to kill the viruses, bacteria and Other harmful gases are not possible. In order to fully eliminate the damage of viruses and bacteria to the human body, it is best to use the ozone sterilization method. Not only can ozone destroy bacteria and viruses in the air, but it is also effective in water. The basic principle of ozone disinfection is that it can oxidize the cell body of the virus and destroy its nucleus. . Ozone technology was discovered by German scientist Mr. Schoenbein in 1840, ozone generator tube was invented by W.von Siemens in 1857, and the sterilization and disinfection effect of ozone was discovered by Mr. Fox in 1873. By the end of the 19th century, ozone was first used in water Factory disinfection. In the 1920s, ozone was replaced by chlorine, which is more economical in investment and simpler in technology. Until the 1950s, ozone was widely used by developed countries for its broad spectrum and high efficiency.

(2). Application of air disinfection ozone in GMP certification of pharmaceutical factories

China's GMP regulations have extremely strict requirements for pharmaceutical production (especially sterile products). In the process of GMP verification, people strongly recommend the ozone sterilization method. Compared with various traditional sterilization methods, ozone sterilization has many characteristics, therefore, ozone sterilization has a wide range of uses in pharmaceutical production. At present, the widely used ones are: sterilization of pipeline containers; sterilization of clean areas using a central air-conditioning purification system; sterilization of original auxiliary materials and working utensils; sterilization of confined spaces; Sterilization.

Ozone disinfection has many unique advantages:

High diffusivity: Ozone is a gas with good diffusivity, no dead angle, and even concentration distribution.

Strong sterilization ability: ozone sterilization ability is equivalent to peracetic acid, higher than other disinfectants.

Broad spectrum: suitable for a variety of pathogenic microorganisms, and has a good killing effect on viruses, fungi and other microorganisms.

Raw materials are easily available: ozone preparation is made using deionized water.

Environmental protection: Ozone can be quickly decomposed into oxygen and monoatomic oxygen, and reduced into oxygen molecules. Recognized as a green disinfectant
