Working principle, precautions and instructions of ultraviolet sterilizer

Working principle of ultraviolet sterilizer: Ultraviolet rays irradiate bacteria or cells, causing a large number of bacteria or cells to sustain life. Nucleic acid molecules in nucleoproteins, which absorb a large amount of ultraviolet rays, undergo sexual changes, destroying physiological activity, and are generally considered to have a bactericidal effect. The higher ultraviolet wavelength is 260.0nm. Among the existing artificial light sources, the special spectral line 253.7nm of the low-pressure pump lamp is closer to 260.0nm, so it has a strong bactericidal effect. However, although the general low-pressure pump lamp is at 253.7nm Most of the radiant energy is concentrated, and it also has a considerable intensity at the spectral line 185.0nm. Ultraviolet rays with a wavelength less than 200.0nm can be quickly absorbed by the air to produce ozone. At the same time, the resistivity of ultra-pure water is reduced, so the use of general low-pressure pump lights and flowing water sterilization devices cannot meet the requirements of ultra-pure water systems in the electronics industry. The ultraviolet sterilizer device adopts a special high-intensity ozone-free ultraviolet germicidal lamp and a stainless steel cylinder with a specially treated micro-carbon odor body on the inner wall. The over-flow stainless steel reaction chamber is made of 304 or 316L material, which is welded automatically. All the teeth are welded smoothly without dead angle after drawing and stretching. The inner and outer polished high-brightness mirror chamber greatly enhances the intensity of ultraviolet radiation and enhances the sterilization effect. The side of the body is specially polished, so that the pretreated water is irradiated with enough 253.7nm ultraviolet rays when it flows through the cylinder, which has a good effect and effectively reduces the impact on ultra-pure water.

The structure of the ultraviolet disinfection sterilizer 1. Ultraviolet lamp tube 2. Quartz glass casing 3. Ballast power supply 4. The characteristics of the stainless steel body ultraviolet sterilizer 1. It can quickly and effectively kill various bacteria, viruses and other microorganisms; 2. Through photolysis, it can effectively degrade chloride in water; 3. Simple operation and convenient maintenance; 4. Small footprint, large amount of water to be treated; 5. No pollution, strong environmental protection, no toxic and side effects; 6. Investment Low cost, low operating cost, and easy equipment installation; 7. A unique inner wall treatment process is designed using optical principles, so that ultraviolet rays can be used to the greatest extent in the cavity, and the bactericidal effect is doubled. Precautions and instructions for use of ultraviolet disinfection and sterilizer 1. Ultraviolet rays cannot directly irradiate the skin of the human body; 2. Ultraviolet rays have certain requirements for the temperature and humidity of the working environment: above 20°C, the irradiation intensity is relatively stable; at 5～20°C When the relative humidity is below 60%, the bactericidal ability is strong; when the humidity increases to 70%, the sensitivity of microorganisms to ultraviolet rays decreases; when the humidity increases to 90%, the bactericidal ability declines by 30% ~40%. 3. When disinfecting water, the thickness of the water layer should be less than 2cm. When the water flows through, the irradiation dose of more than 90000 UW.S/cm2 can be used to achieve effective disinfection of the water.

4. When there is dust and oil on the surface of the ultraviolet lamp tube and sleeve, it will hinder the penetration of ultraviolet light, so it should be wiped frequently (usually once every two weeks) with alcohol, sterilization time, and ammonia water. 5. When the lamp is started, it takes several minutes to heat up to a stable state, and the terminal voltage is relatively high. If it is turned on again immediately after closing, it is often difficult to start, and it is easy to damage the lamp tube and reduce the service life of the lamp tube, so it is generally not suitable to start frequently.
