The sterilization principle of the microwave ultraviolet water treatment equipment is mainly to use the irradiation intensity of the ultraviolet lamp, that is, the radiation intensity emitted by the ultraviolet sterilization lamp, which is inversely proportional to the distance of the irradiated disinfectant. Therefore, when the irradiation reaches a certain level, the disinfectant it is exposed to will stay longer, and the closer it is to the sterilization lamp, the better the sterilization effect will be, otherwise, the worse it will be. So, what are the sterilization principles and application characteristics of the submerged microwave ultraviolet water treatment equipment? Now, let's discuss it with you! After absorbing ultraviolet rays, microorganisms will cause some changes in the structure of nucleoprotein molecules in their own cells, resulting in protein denaturation and breakage on the DNA chain, as well as destruction of cross links in DNA molecules, hydration on cytosine and uracil, and even dimers on adenosine, Because dimerization destroys the normal pairing of purine and pyrimidine, it changes the biological activity of DNA. As a result, the metabolism of microorganisms will be hindered, and they cannot proliferate, produce cells and destroy them; Causes the synthesis of proteins and enzymes in bacteria to be blocked, new type UV photo oxygen microwave deodorization equipment As a result, the structure and function will be changed and destroyed, which will lead to the death of microorganisms and achieve the purpose of disinfection and sterilization. Experiments have proved that UV is the most bactericidal in the range of 240nm to 280nm, especially when the wavelength is 253.7 μ m, UV photo oxygen microwave deodorization equipment manufactor The germicidal effect of ultraviolet radiation is the best. Because a section of C frequency in the ultraviolet ray is very effective in destroying harmful bacteria or viruses. Because UV can kill bacteria, molds, viruses, unicellular algae and other organisms, UV is the preferred equipment for sterilization in the microwave UV water treatment equipment industry.

Microwave and ultraviolet water treatment equipment is a special form of material operation, which is a particle flow without connection. 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 to the DNA and RNA of bacteria and viruses, and can make bacteria and viruses lose their viability and fecundity, thereby eliminating bacteria and viruses, achieving 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 generation of free radicals can cause photoionization, thus leading to cell death. UV photo oxygen microwave deodorization equipment 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. new type UV photo oxygen microwave deodorization equipment When the irradiation intensity is constant, the longer the irradiated disinfectant stays, the closer it is to the germicidal lamp, the better its germicidal effect, and vice versa. With strong destructive power, it can make bacteria and viruses lose their viability and reproduction, and then eliminate bacteria and viruses to achieve disinfection and sterilization effect.

The sterilization principle of microwave electrodeless ultraviolet sterilization equipment is to use the sterilization ability of ultraviolet light. Can ultraviolet light directly kill microorganisms? UV photo oxygen microwave deodorization equipment manufactor According to different biological effects, ultraviolet light is generally divided into four parts according to wavelength: A-band (UV-A), new type UV photo oxygen microwave deodorization equipment 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.

Compared with traditional water disinfection methods such as chlorine disinfection, new type UV photo oxygen microwave deodorization equipment Microwave electrodeless ultraviolet sterilization equipment is relatively safe and environmentally friendly. Chlorine agent is used for disinfection. When chlorine kills germs in water, due to its strong oxidation, it reacts with natural organic substances in water and generates disinfection by-products such as trichloromethane and haloacetic acid, UV photo oxygen microwave deodorization equipment manufactor They all have potential carcinogenicity and certain mutagenicity to human body. Trichloromethane is also classified as Category 2B carcinogen in the list of carcinogens published by the International Cancer Research Institute of the World Health Organization, which poses a health threat of carcinogenicity, teratogenicity and mutagenicity.

VOCS catalytic combustion waste gas treatment equipment in paint shop: Catalytic combustion equipment is a kind of deodorization and deodorization waste gas treatment equipment. The concept of catalytic combustion is to use the catalytic incineration reaction of combustibles under the effect of catalyst and certain temperature conditions. Combustibles are burned under the effect of catalyst. Compared with direct incineration, catalytic incineration has a lower temperature and is quite safe. Catalytic principle and equipment composition (1) Catalyst is defined as a substance that can improve the rate of chemical reaction, control the direction of reaction, and keep its chemical properties unchanged before and after reaction. (2) The mechanism of catalytic effect The mechanism of catalytic effect is a very complicated problem, which is only briefly introduced here. In a chemical reaction process, the participation of the catalyst cannot change the original chemical balance, but only the speed of the chemical reaction. Before and after the reaction, the nature of the catalyst itself does not change. So, how does the catalyst speed up the response? The catalyst has not changed before and after the reaction, so has the catalyst participated in the reaction? In practice, the catalyst itself has participated in the reaction. It is because of its participation that the reaction has changed the original path, reduced the activation energy, and then accelerated the reaction speed. For example, the reaction A+B → C is transited through the central active complex (AB), that is, the reaction speed of A+B → [AB] → C is slow. After participating in catalyst K, the reaction is completed in an easy way: A+B+2K → [AK]+[BK] → [CK]+K → C+2K center no longer needs the transition from [AB] to C, and then the reaction speed is accelerated without changing the catalyst properties. (3) Process composition of catalytic incineration equipment: different emission occasions and different exhaust gases have different process flows. However, no matter which process flow is adopted, it is composed of the following process units. ① Waste gas pretreatment In order to avoid blocking of the catalyst bed and catalyst poisoning, it is necessary to pretreat the waste gas before entering the bed to remove the dust, droplets and catalyst poisons in the waste gas. ② Preheating equipment Preheating equipment includes waste gas preheating equipment and catalyst incinerator preheating equipment. Because all catalysts have a catalytic activity temperature, it is called catalyst ignition temperature for catalytic incineration. It is necessary to make the temperature of exhaust gas and bed reach the ignition temperature before catalytic incineration. Therefore, it is necessary to set up preheating equipment. However, for occasions where the exhaust gas temperature is high, such as enameled wire, insulating material, baking varnish, etc., and the temperature can reach more than 300 ℃, preheating equipment is not required. The hot gas heated by the preheating equipment can be arranged in the heat exchanger and bed. The heat source of the preheater can be flue gas or electric heating, and now electric heating is more used. When catalytic reaction starts, exhaust gas can be preheated with recovered reaction heat as far as possible. In the case of high reaction heat, waste heat recovery equipment should also be set to save power. The heat source temperature of preheated exhaust gas generally exceeds the catalyst activity temperature. In order to maintain the catalyst, the heating equipment should be kept a certain distance from the catalytic incineration equipment, so that the exhaust gas temperature can be evenly distributed. Starting from the need for preheating, catalytic incineration is applicable to the purification of continuous exhaust. If intermittent exhaust, not only each preheating needs energy, but also the reaction heat can not be recycled, which will result in great power waste. This should be noted in planning and selection. ③ Fixed bed catalytic reverberator is generally selected as catalytic incineration equipment. The planning of the reverberator shall be carried out according to the standard, which shall be convenient for operation, repair and catalyst loading and unloading. In the process planning of catalytic incineration, it is necessary to plan the built-up process of components according to the specific situation in the case of large air volume, that is, the preheater and the reverberator are installed separately, and the pipes are connected between them. For occasions with small air volume, catalytic incinerators can be selected to combine preheating and reaction, but pay attention to the distance between preheating section and reaction section. In the catalytic incineration of organic waste gas, the organic waste gas to be treated is easy to explode when mixed with air at high temperature, so the safety problem is very important. Therefore, on the one hand, it is necessary to control the mixing ratio of organic matter and air to keep it at the lower explosive limit; On the other hand, the catalytic incineration system should be equipped with monitoring and alarm equipment and explosion-proof measures.
