Microwave and ultraviolet water treatment equipment is a special form of material operation, which is a particle flow without connection. Each UV photon with a wavelength of 253.7 nm has an energy of 4.9 eV. 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 the DNA and RNA of bacteria and viruses, and can make bacteria and viruses lose their viability and fecundity, thereby eliminating bacteria and viruses, achieving 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 generation of free radicals can cause photoionization, thus leading to cell death. Deodorization of industrial waste gas programme The sterilization principle of the microwave ultraviolet water treatment equipment is to use the irradiation intensity of the ultraviolet lamp, that is, the irradiation intensity emitted by the ultraviolet sterilization lamp, which is inversely proportional to the distance of the irradiated disinfectant. Customized Deodorization of industrial waste gas When the irradiation intensity is constant, the longer the irradiated disinfectant stays, the closer it is to the germicidal lamp, the better its germicidal effect, and vice versa. With strong destructive power, it can make bacteria and viruses lose their viability and reproduction, and then eliminate bacteria and viruses to achieve disinfection and sterilization effect.
During the disinfection process, no toxic and harmful by-products will be produced, the composition and performance of the disinfection water will not be changed, and no secondary pollution will be caused to the water body and the surrounding environment; Reduce chlorine input and residual chlorine, Customized Deodorization of industrial waste gas The chlorine content in the swimming pool water reduces the disinfection by-products, making the swimming pool environment more healthy. Deodorization of industrial waste gas programme Small footprint, safe and reliable operation, simple maintenance and low cost. It can be seen that ultraviolet sterilization has the advantages of sterilization, broad-spectrum sterilization, pollution-free, safe and reliable operation, and no toxic by-products. Therefore, it is increasingly used in engineering.
What are the common faults of microwave and ultraviolet water treatment equipment, Customized Deodorization of industrial waste gas Leakage in the water pressure drop equipment system, lack of pressure at the inlet of the high-pressure pump, air leakage, water leakage, blockage of the filter element of the precision filter, high-pressure pump fault, etc. may cause the water pressure drop of the equipment. Solution: Overhaul the high-pressure pump and precision filter, and eliminate problems. Deodorization of industrial waste gas programme The increase of equipment water pressure may be due to the error of high-pressure pump outlet scheduling index and the blockage of the pipeline from high-pressure pump to reverse osmosis equipment. Solution: recover the equipment pressure by dispatching the outlet index of the high-pressure pump and cleaning the pipeline between the high-pressure pump and the reverse osmosis equipment. The decrease in water production of the manufacturers of microwave and ultraviolet water treatment equipment may be due to the lower water temperature, lower water pressure, and pollution and blockage of the reverse osmosis membrane. Solution: recover normal production by adjusting the temperature of raw water and cleaning and replacing the reverse osmosis membrane.
1. If linear installation is required, please use the installation method of low water inlet and high water outlet to slow down the water flow rate and increase the effect of ultraviolet radiation. 2. When working, Deodorization of industrial waste gas programme Do not look directly into your eyes with an ultraviolet lamp. When the equipment is open, repeated opening and closing will seriously affect the service life of the lamp. 3. If the water flow is too fast, please install current limiting and pressure limiting devices. 4. If the turbidity of raw water exceeds 5 degrees, a prefilter should be installed to ensure ultraviolet sterilization. 5. Please take out the quartz sleeve every time. Customized Deodorization of industrial waste gas After using the disinfection lamp for two to three months, check the surface for dirt to determine the next time to clean the surface of the quartz sleeve.
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 Deodorization of industrial waste gas 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, Deodorization of industrial waste gas programme 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.
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 the catalyst. At the same time, the energy is released. The energy is replaced by the heat exchange device to maintain the energy of equipment spontaneous combustion. 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.
