The simple answer is yes, even more organisms. The research shows that 254nm ultraviolet light is effective for all food borne pathogens, natural microbiota, mold and yeast. Microwave thawing Price Because the size and shape of microorganisms will affect their absorption of ultraviolet light, the time required to kill each species is also different. How does UV sterilize? production Microwave thawing The working principle of ultraviolet sterilizer, also known as ultraviolet disinfection or ultraviolet germicidal radiation (UVGI), is to destroy some chemical bonds, disrupt the structure of DNA, RNA and protein, resulting in the inability of microorganisms to reproduce. When a microorganism cannot reproduce, it is considered dead because it cannot reproduce in the host body and is no longer infectious.

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 Microwave thawing 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. Microwave thawing Price 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.

The sterilization principle of microwave electrodeless ultraviolet sterilization equipment is to use the sterilization ability of ultraviolet light. Can ultraviolet light directly kill microorganisms? Microwave thawing Price According to different biological effects, ultraviolet light is generally divided into four parts according to wavelength: A-band (UV-A), production Microwave thawing 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.

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.
