The sterilization principle of microwave electrodeless ultraviolet sterilization equipment is to use the sterilization ability of ultraviolet light. Can ultraviolet light directly kill microorganisms? Deodorization of industrial waste gas manufactor According to different biological effects, ultraviolet light is generally divided into four parts according to wavelength: A-band (UV-A), production Deodorization of industrial waste gas Also known as black spot effect ultraviolet (400 ～ 320 nm); B band (UV-B), also known as erythema effect ultraviolet (320 ～ 275 nm); C-band (UV-C), also known as sterilization ultraviolet (275 ～ 200 nm); D-band (UV-D), also known as vacuum ultraviolet ray (200-100 nm). C-band ultraviolet light is mainly used for water disinfection.

Ultraviolet is a kind of light wave invisible to the naked eye, which exists outside the ultraviolet end of the spectrum, so it is called ultraviolet. Ultraviolet ray is one of the electromagnetic waves radiated by the sun. It is a special form of material operation, which is a flow of particles that are not connected. Each UV photon with a wavelength of 253.7 nm has an energy of 4.9 eV. When ultraviolet rays irradiate microorganisms, energy transfer and accumulation will occur, and the accumulation results in the inactivation of microorganisms, thus achieving the purpose of disinfection. When bacteria and viruses absorb more than 3600~65000uW/cm2, it has a strong destructive power on DNA and RNA of bacteria and viruses, and can make bacteria and viruses lose their viability and fecundity, thus eliminating bacteria and viruses, production Deodorization of industrial waste gas Achieve disinfection and sterilization effect. On the one hand, ultraviolet light can mutate nucleic acids, hinder their replication, transcriptional blockade and protein synthesis; On the other hand, the production of free radicals can cause photoionization, which will lead to cell death. Deodorization of industrial waste gas manufactor The sterilization principle of the microwave ultraviolet water treatment equipment is to use the irradiation intensity of the ultraviolet lamp, that is, the irradiation intensity emitted by the ultraviolet sterilization lamp, which is inversely proportional to the distance of the irradiated disinfectant. When the irradiation intensity is constant, the longer the residence time of the irradiated disinfectant is, the closer it is to the sterilization lamp tube, the better the sterilization effect will be. On the contrary, the worse the sterilization effect will be. This equipment can be used in direct drinking water equipment to obtain good water purification effect.

Most of the microwave ultraviolet water treatment equipment is installed in the plant, but some are installed outdoors. When winter comes, the temperature also drops to below zero. Because the volume of water will increase significantly in the process of solidification and freezing, production Deodorization of industrial waste gas Once the microwave and ultraviolet water treatment equipment and pipeline are iced, it will cause the water flowing part of the equipment and pipeline to break, resulting in economic losses. Then let's see how to maintain the microwave ultraviolet water treatment equipment in winter. Deodorization of industrial waste gas manufactor In order to increase the effective thermal insulation measures for outdoor microwave ultraviolet water treatment equipment and pipes, straw rope wrapped with plastic film can be used for thermal insulation, or 1.2-1.5cm thick insulation cotton or insulation cotton pipe can be used for tape wrapping.

Ultraviolet disinfection can ensure sterilization effect and water quality. This is a long-term effective sterilization technology. There is no reactivation reaction and no rebound of flora, ensuring complete disinfection effect and water quality safety. production Deodorization of industrial waste gas Compared with other sterilization methods, UV has many obvious advantages, especially the difference from chemical disinfectants is that UV sterilizers will not bring toxic substances and residues into pure water, and will not change its chemical composition, odor and pH value. This function is very important in the pharmaceutical industry and related industries. Deodorization of industrial waste gas manufactor The chemical dosage of influent often changes the characteristics of the product. It can effectively kill all bacteria and viruses, and inactivate chlorine resistant microorganisms such as Legionella, Escherichia coli and Pseudomonas. Cryptosporidium, amoeba and bacteria.

Have you ever thought about whether you need a sterilizer on your water tank? If so, which Z is better? An aquarium scientist's differences between ozone and ultraviolet sterilizers. Ozone is a gas composed of three oxygen atoms, while the oxygen we breathe is composed of two oxygen atoms. This chemical structure makes ozone highly active, production Deodorization of industrial waste gas That's why it's such a powerful sterilizer. Deodorization of industrial waste gas manufactor It is meaningful that the bulb in the UV germicidal lamp is made of quartz, because quartz will not filter out the UV rays. However, water filters light according to its depth. Therefore, the water flow space between the quartz bulb and the external glass or plastic tube is usually only a few millimeters - a thicker space will reduce the intensity of ultraviolet rays and allow bacteria and other microorganisms to survive.
