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. Microwave drying of cereals manufactor 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. new type Microwave drying of cereals 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.
1. The welding of equipment shell and framework shall be firm without obvious deformation or burn through defects. 2. The equipment surface shall be evenly sprayed with the same color, and the surface shall be free of flow marks, bubbles, paint leakage and peeling. 3. The appearance of the equipment shall be neat and beautiful without obvious hammer marks and unevenness. The panel instruments, switches, indicator lights and labels shall be installed firmly and correctly. In order to ensure the stability of the equipment, we need to replace the lamp regularly, new type Microwave drying of cereals The imported lamp should be replaced after 9000 hours of continuous service or one year to ensure a high disinfection rate. Microwave drying of cereals manufactor When replacing the lamp tube, first pull out the power socket of the lamp tube, pull out the lamp tube, then carefully insert the cleaned new lamp tube into the sterilizer, install the gasket, check for water leakage, and then plug in the power supply. Be careful not to touch the quartz glass of the new lamp tube with your fingers, otherwise the disinfection effect will be affected due to stains.
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, Microwave drying of cereals manufactor 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. new type Microwave drying of cereals 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.
To solve the problem of light reactivation: open the channel to realize underground water outflow, to avoid or reduce the visibility of treated water before entering the pipeline. At the same time, use a dark container containing a sample of test water, new type Microwave drying of cereals It shall be sent for inspection in time to avoid factors such as storage conditions or test time affecting the test results. Improve the light transmittance: adjust the front-end treatment process to reduce the SS mass concentration of water in the UV disinfection device, Microwave drying of cereals manufactor The ultraviolet disinfection I was adjusted to ozone decolorization, which reduced the chromaticity of the influent water to ensure that SS was controlled below 10 mg/L; The front-end technology has been adjusted to strictly control the consumption of PAM and other chemicals, and a defoaming device has been installed at the water inlet of the external disinfection device to reduce the foam content in the water body and increase the light transmittance of the water body.
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 drying of cereals manufactor 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? new type Microwave drying of cereals 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.
In the microwave and ultraviolet water treatment equipment, the reverse osmosis equipment needs three kinds of sealing rings to realize the sealing barrier of each part of the membrane shell. In order to reduce the resistance of the device, water or glycerin should be added to the surface of the sealing ring. new type Microwave drying of cereals Microwave ultraviolet water treatment equipment PP cotton softening equipment. Microwave drying of cereals manufactor Special attention should be paid to the use of petroleum jelly or other petroleum grease lubricants as lubricants. Otherwise, the fresh water pipeline will crack, especially the expansion of the sealant ring. The expansion of the skirt does not directly affect the operation of the system, but will affect the reloading of the system after unloading, that is, the expansion skirt is difficult to enter the slot during loading.
