Description
Technical Field
The utility model relates to an ultraviolet sterilization technical field especially relates to a middling pressure ultraviolet disinfector.
Background
Ultraviolet rays are a part of sunlight, are invisible rays to the naked eye, have a spectrum of 100nm to 400nm, and are located between visible rays and X-rays, as shown in the following figure. According to different wavelengths, the ultraviolet can be divided into four wave bands of 1UVA wave ultraviolet, which is called long wave ultraviolet with the wavelength of 315 to 400 nm; 2UVB wave ultraviolet rays, called medium wave ultraviolet rays, with a wavelength of 280 to 315 nm; 3UVC wave ultraviolet rays, called short wave ultraviolet rays, with the wavelength of 200 to 280 nm; 4VUV wavelength ultraviolet light, referred to as vacuum ultraviolet light, having a wavelength of 100 to 200 nm.
The ultraviolet ray disinfection and sterilization mechanism is that after bacteria and viruses are irradiated by ultraviolet rays, ultraviolet spectrum energy is absorbed by bacterial nuclei, so that nucleic acid structures of the bacteria and the viruses are damaged, and various bacteria, viruses and the like lose replication and reproduction capacity, thereby achieving the sterilization effect.
Ultraviolet lamps (UV lamps) can be classified by energy per CM of tube (W/CM), with commercial UV tubes being classified as 80, 100, 120, 150, 160, and 240W/CM. There is often not a linear relationship between UV output and cure speed. The relationship between the two depends on factors such as the coating, substrate, reflector geometry and overall lamp efficiency, the sensitivity of the pigment material to heat, the thickness of the pigment and coating, etc., which affect the performance of the uv light source.
The most commonly used UV light sources are mercury vapor lamps, which can be divided into three types: low-pressure mercury lamps (10-100 Pa), medium-pressure mercury lamps (100-100000 Pa) and high-pressure mercury lamps (>100000 Pa). The water for the medium-pressure ultraviolet sterilizing swimming pool has the following advantages:
1. strong bactericidal property. The sterilization efficiency is high, the sterilization speed is high, and the sterilization effect on common bacteria and viruses can be generally finished within a few seconds;
2. has high broad-spectrum sterilization. The ultraviolet ray can kill all bacteria and viruses with high efficiency, can permanently inactivate chlorine-resistant microorganism tissues, such as legionella pneumophila, escherichia coli, pseudomonas, cryptosporidium, amoeba, bacteria and the like, and can achieve the inactivation effect by destroying DNA and DNA repair enzyme of the microorganisms;
3. toxic and harmful byproducts are not generated in the disinfection process, the components and the properties of the disinfected water are not changed, and secondary pollution is not generated to the water body and the surrounding environment; the chlorine adding amount and the residual chlorine are reduced, so that the chlorine content in the swimming pool water is reduced, and disinfection byproducts are reduced, so that the swimming pool environment is healthier;
4. the medium-pressure ultraviolet rays have the capacity of degrading the combined chlorine, including monochloramine, dichloramine, trichloroamine and the like, so that the generation of carcinogenic trihalomethane is effectively avoided, and the influence of the combined chlorine on a human body is avoided. The pungent smell in the swimming pool is reduced, the environment that the swimmer plays and moves is effectively improved, and the working environment of the working personnel of the swimming pool is greatly improved.
The weak penetration of ultraviolet rays into liquid and the insufficient disinfection of liquid by medium-pressure ultraviolet lamps are one of the main problems which prevent the popularization and application of medium-pressure ultraviolet lamps in the water disinfection of swimming pools.
