Activated carbon adsorption and catalytic combustion equipment is a common volatile organic waste gas treatment equipment. It is energy-saving, environmental protection, no secondary pollution, and high purification efficiency. It is a very good equipment for VOC waste gas treatment. Generally, the main composition of activated carbon adsorption catalytic combustion equipment is as follows: Pretreatment equipment: since honeycomb activated carbon adsorption requires specific conditions such as temperature, humidity and cleanliness, it is necessary to treat the organic waste gas with different characteristics before entering the activated carbon adsorption. The organic waste gas containing more dust particles needs to be filtered. The waste gas with a temperature greater than 45 ℃ needs to be cooled, and the waste gas containing a large number of water mist particles needs to be separated and filtered. Activated carbon adsorption bed: it can absorb organic waste gas by taking advantage of the porous physical characteristics of activated carbon. The design of the adsorption bed follows the law of two-phase adsorption curve. Only by combining the amount of activated carbon and calculating the cross section wind speed and retention time of activated carbon adsorption can the adsorption efficiency meet the design requirements and meet the emission standards. The box is in negative pressure state during equipment operation, and it is required to be air tight. The desorption temperature of the box is between 70-100 ℃ during the desorption process, and the heat preservation is generally 50mm considering the energy saving and safety factors. Ensure that the temperature of the outer wall of the box is not higher than the normal temperature by 15 ℃. Main exhaust fan: as the main power of the equipment, the exhaust fan guides the air to move according to the specified process. The fan can be selected accurately only when it is stable and reliable, and the resistance calculation of the system is accurate. The operation of the fan will produce noise, and the high-power fan needs to be equipped with a sound insulation room. Attention shall be paid to the design that the wind speed at the air outlet shall not be too high. Catalytic combustion equipment: after the system has operated for a period of time, the activated carbon needs to be regenerated after adsorption saturation to restore the adsorption activity of the activated carbon. The organic waste gas is concentrated in the activated carbon. After the organic matter is separated from the activated carbon layer at low temperature, it is decomposed into water and carbon dioxide at about 300 ℃ through the action of catalyst. At the same time, the energy is released. The energy is replaced by the heat exchange device to maintain the energy of spontaneous combustion of the equipment. For a single activated carbon adsorption bed, the desorption time is 2-2.5 hours. The set time of activated carbon adsorption box is automatically switched to desorption regularly. The service life of the ceramic honeycomb noble metal catalyst loaded inside is 8000 hours. The whole desorption system adopts multi-point temperature control to ensure the stability of desorption effect. The selection of organic waste gas catalyst is the core of this equipment. Valve switching system: valves include adsorption system valve, desorption system valve, cooling and emergency discharge valve. The three types of valves are required to be timely and accordingly to ensure that the air leakage rate is less than 2%. The conventional galvanized sheet air valve in the market has air leakage due to unreliable sealing, so it is necessary to select the high temperature resistant air valve with silicone gasket. The temperature is reliable when opening and closing the valve. Due to the temperature of the gas through which the valve passes, it is very easy for conventional plastic electric actuators to age and deform, resulting in ineffective execution. Generally, long rod actuators are used.

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, Customized Microwave drying of cereals 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, Microwave drying of cereals Price 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.

UV disinfection is an efficient, non organic chemical way to prevent mildew, Customized Microwave drying of cereals The maintenance is low-cost and pollution-free. As a purely physical disinfection method, the microwave electrodeless ultraviolet sterilization equipment can not only reasonably remove most of the microbial strains in the water. Moreover, it is not easy to cause all disinfection and combustion products, thus ensuring that the level of microbial strains in tap water points is within the required product quality standards, Microwave drying of cereals Price The microwave electrodeless ultraviolet sterilization equipment has the advantages of simplicity, convenience, broad-spectrum, high efficiency, pollution-free, convenient management and automation technology.

Compared with ordinary vacuum cleaners, the industrial central dust collector has a powerful dust collection function and can be cleaned quickly, avoiding secondary pollution caused by dust and noise pollution: 1. The dusty gas enters the ash hopper of each sub room from the air inlet equalizing pipe of the dust remover. The central dust removal of the workshop is customized and guided by the ash hopper guide device. 　　 2. The large particles of dust are separated and directly fall into the ash hopper, while the fine dust enters the middle box evenly and is adsorbed on the outer surface of the filter bag. Clean gas enters the upper box through the filter bag and is discharged into the atmosphere through offline valves and exhaust pipes. 　　 3. Timing or manual cleaning can be adopted: each chamber of the pulse bag filter will be cleaned in turn, and the chamber that has completed the cleaning will be restored to the dedusting state immediately. 　　 4. Open the electric control pulse valve according to the set procedure, stop air blowing, use the compressed air instantaneous blowing to increase the pressure in the filter bag, shake the dust on the filter bag into the ash bucket, and discharge it by the ash discharge mechanism. 　　 5. With the increasing dust on the outer surface of the filter bag, the differential pressure monitoring system will send a signal when the equipment resistance reaches the set value. 　　 6. The dust removal mechanism starts to work, and compressed air is sprayed from the pulse valve, and then shot into the filter bag through the blowing pipe and nozzle. The filter bag expands and vibrates instantaneously, so that the dust on the surface is removed and dropped into the ash hopper, which is discharged by the ash discharge valve. 　　 7. With the progress of filtering conditions, the dust on the filter bag will accumulate more and more. When the equipment resistance reaches the limited resistance value, the ash removal control device will automatically close the offline valve of one chamber according to the differential pressure setting value or the ash removal time setting value.
