Description
Technical Field
The invention relates to the technical field of ultraviolet disinfection, in particular to a full-automatic high-adaptability wide-spectrum IPUV high-energy pulse ultraviolet disinfection system.
Background
Ultraviolet rays exist in sunlight, but ultraviolet rays in natural light have limited irradiation energy. Artificially obtained ultraviolet radiation (UVR) is an electromagnetic wave in the ultraviolet band generated by plasma luminescence or solid luminescence. Uv sterilization is one of the most common and oldest sterilization and disinfection techniques in medicine, and is an effective method for inactivating viruses and bacteria on solid surfaces, water, and in the air, which has been in history for hundreds of years so far. As early as the 19 th century, the use of uv light for disinfection was mentioned in Downes and Blunt studies. Danish scientists Niels Ryberg Finsen apply ultraviolet rays to the field of medical health, and realize treatment of skin diseases by ultraviolet sterilization. In 190 years, he was awarded a nobel physiological or medical prize. In 2003, the experts of the Chinese disease prevention and control center research and discovery show that the Chinese medicine composition is strong in useThe degree is more than 90 mu W/cm2The ultraviolet ray irradiates the coronavirus at the position of 80cm for 60min, so that the virus can be effectively killed. Compared with the disinfection modes of medical alcohol, disinfectant and the like, the ultraviolet disinfection technology is a physical disinfection method and has the advantages of high efficiency, rapidness, convenience, no secondary pollution, simplicity, practicability, easy operation and the like.
Ultraviolet radiation is generally divided into three types by wavelength: ultraviolet radiation with the wavelength of 315-400 nm is called ultraviolet radiation A band (UV-A for short); ultraviolet radiation with the wavelength of 280-315 nm is called an ultraviolet radiation B wave band (called UV-B for short); ultraviolet radiation with a wavelength of 100-280 nm is called ultraviolet radiation C band (UV-C for short). Among them, the UV-C band has the highest energy but the shortest wavelength, which is easily absorbed in the atmosphere, causes severe attenuation, and is also called "solar blind" UV band because it contains almost no UV light in the near-earth solar spectrum.
The inactivation mechanism of the microorganisms by destroying nucleic acid sterilization ultraviolet rays mainly utilizes the absorption of the ultraviolet rays by the nucleic acids (DNA and RNA) of the microorganisms to destroy the functions of the nucleic acids, thereby realizing disinfection and purification. When nucleic acids are irradiated with ultraviolet rays, ultraviolet light is absorbed in a large amount, and thus, a part of m-diazepine (mainly composed of protease) and isomers of m-diazepine are formed in vivo. This substance can cause metabolic dysfunction of the bacteria themselves and cause genetic problems in the bacteria, and continued exposure to ultraviolet radiation can ultimately lead to the death of the bacterial population for the reasons described above. DNA has the strongest absorption to ultraviolet rays with the wavelength of 265nm, and has the sterilization effect when the wavelength of light is below 300 nm; and the sterilizing effect is most obvious near 265 nm. The ozone-generating sterilizing low-pressure mercury vapor discharge can generate ultraviolet rays of 254nm and 185nm, after the ultraviolet rays are emitted from the glass tube, the ultraviolet rays of 254nm are absorbed by microorganisms, and the ultraviolet rays of 185nm and air react to generate ozone. When oxygen molecules in the air absorb ultraviolet light with the central wavelength of 185nm of the germicidal lamp, the photosensitization utilizes high-energy high-ozone ultraviolet light beams to decompose the oxygen molecules in the air to generate free oxygen (namely active oxygen) which is carried by the free oxygenThe negative electrons are not balanced and therefore need to combine with oxygen molecules to produce ozone. Ozone has strong oxidizing property, can kill bacteria propagules, spores, viruses, fungi and the like, can destroy botulinum toxin, and can inactivate enzyme by strong oxidizing action to cause death of microorganisms. The ozone has obvious effect of killing microbes in the air, and 30mg/m is adopted3The ozone with the concentration acts for 15min, the killing rate of the natural bacteria can reach more than 90 percent, and the ozone can remove peculiar smell, purify the environment and refresh the air.
