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.

The microwave electrodeless ultraviolet sterilization equipment depends on the molecular formula of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in human body cells of microbial strains that can be destroyed by using ultraviolet light of moderate wavelength, production Microwave liquid sterilization It leads to death of growth and development somatic cells and (or) death of regenerative somatic cells, which exceeds the actual effect of disinfection and sterilization. Microwave liquid sterilization Price Ultraviolet disinfection technology is based on the application scenario of contemporary management, medicine and photodynamic models. With the unique design concept of high efficiency, high tenacity and long life UVC light wave ultraviolet direct water flow, all kinds of bacteria, virus infections, parasites, algae and other pathogenic bacteria in the water are immediately killed, which exceeds the actual effect of disinfection and sterilization.

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 liquid sterilization 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 liquid sterilization 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 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 radiation is one of the electromagnetic waves from the sun, and it is usually divided into four categories according to the wavelength. The following is a special form of material operation, which is a particle stream with disconnected particles. Each UV photon with a wavelength of 253.7 nm has an energy of 4.9 eV. production Microwave liquid sterilization 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 DNA and RNA of bacteria and viruses, Microwave liquid sterilization Price It can make bacteria and viruses lose their viability and fecundity, and then eliminate bacteria and viruses to 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.

working principle: The thermal storage catalytic combustion equipment uses natural gas to directly burn organic waste gas. Under the temperature of 750~850 ℃, organic molecules are decomposed into CO2 and H2O. The burned flue gas accumulates heat in the ceramic through the thermal storage ceramic brick, preheats the organic waste gas, and then discharges it. The inlet and outlet directions of the waste gas are automatically switched by the switch valve, and work circularly, RTO can fully recover and burn organic decomposition heat energy, which greatly reduces the energy consumption of the system.

With the extension of the use time of the clean microwave ultraviolet water treatment equipment, it is a normal phenomenon that the water production decreases. The decrease of water production in winter is due to the decrease of water temperature and permeability, and the change of reverse osmosis membrane density. These two reasons will reduce the water production of microwave and ultraviolet water treatment equipment. Strengthen pretreatment device, production Microwave liquid sterilization Increasing the cleaning time, replacing the filter element frequently, backwashing the reverse osmosis membrane in time, and extending the interval are all ways to promote the normal operation of the microwave ultraviolet water treatment equipment. Microwave liquid sterilization Price If the water pipe or microwave ultraviolet water treatment equipment is frozen, the valve shall be closed in time, wrapped with towel, and slowly watered with warm water. Do not directly use fire for barbecue, nor use boiling water for heating, so as to prevent microwave and ultraviolet water treatment equipment and pipelines from cracking, or use a hair dryer to dry them. At the same time, gently tap hard objects on the water pipe until the pipe freezes and thaws, and the tap water flows out smoothly. If the fully automatic frequency conversion water supply equipment has been frozen, it can only be wrapped with a hot towel and sprinkled with warm water until the pipe freezes and thaws, so that the water can flow out smoothly.
