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 components of activated carbon adsorption catalytic combustion equipment are 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.

After years of development, microwave electrodeless UV sterilization equipment has been widely used in drinking water, food, beverages, electronic products, chemicals, medicine, sewage microwave UV water treatment equipment and other fields. Microwave extraction equipment programme High intensity odorless UV germicidal lamp is used to simplify the special stainless steel inner wall, so that the pretreated water has enough UV when passing through the UV. new type Microwave extraction equipment Irradiation has good sterilization effect. In addition, it has the advantages of simplicity, convenience, broad-spectrum, no secondary pollution, convenient management and automation.

The microwave electrodeless ultraviolet sterilization equipment can ensure the sterilization effect and water quality of the effluent. It is a durable and effective sterilization technology. There is no reactivation reaction and no rebound of bacteria, ensuring complete disinfection effect and water quality safety. Compared with other sterilization methods, UV has many obvious advantages, new type Microwave extraction equipment In particular, unlike chemical fungicides, the ultraviolet sterilizer will not bring toxic substances and residual substances into purified water, Microwave extraction equipment programme The chemical composition, odor and pH value of the fluid will not be changed. This feature is very important in pharmaceutical industry and related industries. The chemical dosage of influent can often change the characteristics of products.

The technology of microwave ultraviolet water treatment equipment is to use double layer ultrafiltration membrane for microwave ultraviolet water treatment equipment, or combine ultrafiltration membrane and reverse osmosis filtration membrane for application. Microwave extraction equipment programme When the manufacturer of microwave ultraviolet water treatment equipment applies external pressure on the concentrated solution side, the penetration speed will decrease. When the pressure increases to a certain value, the penetration process will stop and the so-called penetration balance will be reached. The external pressure under the balance condition is called the penetration pressure. When the pressure on the concentrated solution side continues to increase, that is, when the applied pressure is greater than the penetration pressure, The solvent of purified water equipment will reverse its original soaking direction and enter the dilute solution side from the concentrated solution side through the semi permeable membrane, new type Microwave extraction equipment This phenomenon is called reverse osmosis. For a long time, it will not only affect the effluent quality of the equipment, but also lead to the fouling of the reverse osmosis membrane of the main components of the equipment, resulting in the small output of the pure water equipment, the substandard effluent quality, or the equipment can not be used. In order to ensure the continuous and safe operation of pure water equipment, the maintenance of pure water equipment is very important.

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. Catalytic combustion equipment is applicable to industries: Applicable to the treatment of mixed combustible organic waste gas and odor with large and medium concentration (thousands of ppm) and medium air volume Applicable to waste gas treatment in paint shop Applicable to waste gas treatment of electronic product manufacturing and integrated circuit Applicable to waste gas treatment in printing process and injection molding process Applicable to the treatment of organic waste gas generated in petrochemical, medical and other industries Technical features of regenerative catalytic combustion equipment: Wide range of exhaust gas; High waste gas treatment efficiency; Less maintenance work, safe and reliable; Low pressure loss and high purification efficiency; Long service life of equipment; Low operation cost
