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.

UV disinfection is generally only used for air and instrument surface disinfection. Surgical dressings cannot be treated by UV radiation as a routine method. Ultraviolet radiation is the general term of radiation in electromagnetic spectrum with wavelength from 10nm to 400nm, which can not cause people's vision. In 1801, German physicist Ritter found that the ultraviolet ray could sensitize the photographic negative containing silver bromide at the outer part of the ultraviolet end of the sunlight spectrum, so he found the existence of ultraviolet ray. Too much ultraviolet rays entering the body will cause skin cancer. production Microwave drying It can be disinfected after use every day. It should be disinfected two or three times a week. It is recommended that the toothbrush head should be replaced every three months. It can be disinfected every day. The SEGA toothbrush sterilizer I selected should be disinfected for 6-8 minutes each time. It is a good ultraviolet disinfection lamp. It needs to be equipped with a ballast. Mould formation is due to long-term lack of ventilation and humidity, Microwave drying manufactor If ventilation and moisture removal are available, mold will not grow. Since mold has been formed, first kill it with a mold remover, and then put a moisture bag such as a charcoal bag. I often do on-site mildew and odor removal projects. You can sprinkle lime on the corner of the wall or place charcoal in the house to absorb moisture when the house is wet. In addition, don't open the window in foggy or rainy weather. Open the window in good weather to ventilate in time.

The microwave ultraviolet water treatment equipment has many advantages, such as good light conditions, low energy consumption, thorough sterilization, and flexible installation of equipment. Not only that, the beautiful appearance also attracts many manufacturers to buy. Microwave drying manufactor Ultraviolet germicidal lamp should pay attention to the decline of the radiation intensity of the lamp tube. After using it for a period of time, we still use the fluorescent lamp concept to evaluate the lamp tube, and judge the invisible light intensity by the intensity of the visible light. This method is prone to errors, production Microwave drying So as to affect the sterilization effect.

During the installation of the microwave and ultraviolet water treatment equipment, the commissioning shall be carried out continuously, production Microwave drying A lot of work needs to be completed before installation. For example, some of their installations must meet the final installation standards and have the final acceptance standards, so that there can be more ways to deal with it, Microwave drying manufactor The operation shall be carried out according to the relevant design requirements as far as possible, and all operations can be accepted during the operation process, so as to ensure the actual use.

The gas of organic matter discharged from the workshop is subject to particle filtration and desorption after adsorption, and the high concentration organic waste gas from desorption is discharged after catalytic combustion. (The desorbed high concentration organic waste gas enters the catalytic chamber for catalytic combustion after heat exchange, and the discharged hot air desorbs and regenerates the adsorption bed and circulates in turn).

Microwave electrodeless ultraviolet sterilization equipment has high value in microwave ultraviolet water treatment equipment, production Microwave drying It destroys and changes the structure of DNA of microorganisms through the irradiation of ultraviolet light, so that the bacteria will die immediately or cannot reproduce, so as to achieve the purpose of sterilization. The real bactericidal effect is UVC ultraviolet, Microwave drying manufactor Because C-band ultraviolet light is easily absorbed by the DNA of organisms, the ultraviolet light of about 253.7 nm is preferred. It is a pure physical disinfection method, which has the advantages of simplicity, convenience, broad-spectrum, no secondary pollution, convenient management and automation. With the introduction of various new designed ultraviolet lamps, the application range of ultraviolet sterilization is also expanding.
