Structural analysis of ultraviolet sterilizer:

1.Shell material: Stainless steel reaction chamber adopts imported thickened wall thickness304Stainless steel material. Stainless steel has a chromium content of10%-30%The general term for a type of alloy steel, chromium is used to make the steel as resistant to oxidation as possible. There are three main types of stainless steel: austenitic stainless steel, ferritic stainless steel, and martensitic stainless steel. Austenitic stainless steel has the highest corrosion resistance, no magnetism, and heat treatment cannot change its microstructure.304Stainless steel belongs to austenitic stainless steel, nickel（Ni）The content is greater than8%Chromium（Cr）The content is greater than18%So it's also called18/8stainless steel.304The biggest feature of stainless steel is wear resistance and corrosion resistance. The application areas include aircraft industry, dairy products, and food processing industry.
UV sterilizer for removal304In addition to stainless steel, other companies also use carbon steel as the shell. The characteristics of carbon steel are high carbon content, high hardness, and low price. The carbon content of carbon steel is0.02%-2%Between them, the strength of carbon steel is low, with a yield to strength ratio of0.6The weight of the components will increase; In addition, carbon steel is not corrosion-resistant, not resistant to high temperatures, and has magnetism. During the water treatment process, various types of water quality (strong acid or strong alkali) will be encountered, which will affect its service life. Therefore, it is not recommended to choose carbon steel UV sterilizers.
2.UV lamp tube, made of quartz glass (high UV transmittance) and ceramic lamp head (wear-resistant), installed in the quartz sleeve inside the reactor, parallel to the direction of water flow. The effective working life of the lamp tube is not less than9000Hour, generated254nmUV output, coupled with high-efficiency electronic ballasts, further enhances the lifespan and effectiveness of the entire sterilizer, with a sterilization rate of up to99.99%.
3.Quartz tube: UV sterilization lamp belongs to low-pressure mercury lamp, and mercury emits two peak rays:253.7nmand185nmBut the wavelength that has the best bactericidal effect is253.7nmTherefore, quartz glass is usually used to filter it out185nmAnd quartz glass is253.7nmThe ultraviolet transmittance is very high. The UV sterilizer uses a high transmittance quartz tube, which has a transmittance greater than90%Divided into single end opening and double end opening2Seed. Excellent UV penetration rate ensures high-intensity UV output.
4.Electronic ballast: It has good voltage stabilization performance and can maintain constant power of the light source and stable illumination even when there is a large deviation in power and voltage. The electronic ballast used in the ultraviolet sterilizer has very low noise and can achieve35dbBelow, people can hardly feel the noise and it does not affect their other work. In addition, the use of electronic ballasts in ultraviolet disinfectors can extend the service life of the lamp tube, without the need for a starter. The ultraviolet lamp tube is not repeatedly impacted or flickered, and will not turn black too early. It can be started at once, reducing the workload of repairing and replacing the starter and lamp tube.
5.Sealing ring: Made of food grade transparent silicone and a trapezoidal structure with a special mold, the sealing effect is excellent, replacingOO-ring to prevent water leakage caused by improper installation.
6.Processing technology: Made by fully automatic welding, all the passes are welded smoothly without dead corners after punching and stretching. The high brightness cavity with internal and external polishing will enhance the ultraviolet radiation intensity and enhance the sterilization effect. Thickened cavity design, capable of withstanding pressure up to0.8MpaStrict air pressure and water pressure testing at the factory completely eliminates water leakage.
7.UV irradiation intensity sensor/UV irradiation intensity monitor: The UV irradiation intensity sensor can monitor the output intensity of the UV disinfection system in real-time online and output0-5Vperhaps4-20mAShow mixed signals and provide them to the monitoring device for use. The ultraviolet irradiation intensity monitoring device receives signals from sensors and can set the alarm value of irradiation intensity and the service life of the lamp tube according to requirements. Real time monitoring of the system to ensure the normal operation of equipment.
