PDC-200 UV disinfection instrument 5

UV disinfection UV disinfection 13,833,174,989 for pipeline, using the world's leading high-intensity ultraviolet light, odorless, wall specially treated food grade three 204 stainless steel, so that when the cylinder had been pretreated water wavelength of 254nm UV enough exposure, with good bactericidal effect, because he does not change the physical and chemical properties of water, so the secondary water supply, food, beverage, chemical, electronics, medicine, sewage, water is indispensable for the best. UV germicidal UV is an introduction to the principles of electromagnetic wave, when the atomic electron to jump from the low energy bands energy bands, will release excess energy electromagnetic waves. Electromagnetic energy, the stronger, the shorter the wavelength, the wavelength of the human eye can see more than four hundred nm, to the naked eye, the four hundred nm waves appear as blue, purple, 780nm waves appear as yellow, red. UV refers nm wavelength shorter than four hundred waves, because the spectral region in addition to purple, named for the UV (Ultraviolet, referred to as UV). Refers to a wavelength in the UV through one hundred - four hundred nm of the electromagnetic wave, the human eye can not see ultraviolet light. One hundred - four hundred nm wavelength ultraviolet light, according to their impact on the human body and function, UV-A, UV-B, UV-C and V-UV. UV-A is the mean wavelength UV 315 nm, four hundred, UV-A can make a person's skin to produce melanin, the skin black. UV-B is in the 280-315nm wavelength ultraviolet, UV-B can cause cancer, skin aging wrinkles. UV-C wavelengths 200-280nm, 254nm band which sterilization, disinfection efficacy. Wavelength 240-270nm of UV-C directly damage cells, viral DNA (deoxyribonucleic acid) and RNA (ribonucleic acid), microorganisms rapid death. Wavelength hundred -200nm of VUV185nm produce ozone, and ozone in the air or dissolved in water, can cell walls of microorganisms to oxidation damage, microorganisms immediately killed. Known on Earth in the form of life, are based on DNA and RNA as a basis for breeding, the remains of all. DNA and RNA are in four kinds of chemical units A - Adenine adenine T - Thymine Thymine C - Cytosine cytosine, oxygen sulfamethoxazole cell proliferation, DNA in the long chain open, open long after each A unit chain length will look even close basis of new cells each long chain can replicate the same with another long chain chain just isolated to restore the original intact DNA division before becoming T cells. 240-270nm wavelength UV can break the ability to produce proteins and DNA replication. Bacteria and viruses DNA, RNA damaged after their reproductive capacity and capability to produce proteins have been lost. Caused by bacteria, viruses are generally very short life cycle, can not breed bacteria, viruses will quickly die. Horizontal, sterilization speed, high efficiency, good effect, according to the water treatment requirements of irradiated for 10 seconds, the water can kill viruses, bacteria, sterilization rate of 99.99%. After irradiation of the water, will not change its physical and chemical properties, it will not cause pollution. Simple, easy to use, has a different flow of styling products for users to choose only need regular replacement of ultraviolet light disinfection and cleaning of the quartz sleeve can be. Small size, light weight, low power consumption, long life, low cost, compared with other sterilization methods have significant advantages, it is widely used; this device by ultraviolet lamps, quartz tube, ballast, seals, composed of tanks, water outlet and other parts. Second, the process considerations normal operation, do not be stopped by unplugging the power switching devices work, or easily cause an electric shock do not knot the power cord, stretch, heavy pressure, high-temperature heating, otherwise it will cause damage to the power supply do not own unauthorized repairs equipment, construction electrician must not use other hard object impact, hitting equipment cylinder cavity ○ maintain equipment, control cabinet dry, clean, avoid water droplets trickle ○ equipment cabinet cavity, near the control cabinet so as not to put their things do not affect the device to work in the device cavity, the control cabinet placed objects. ○ user-supplied electrical power must be in accordance with national safety regulations grounded ○ If abnormal phenomenon, immediately turn off the power to stop the operation. Continuous operation is in an abnormal state can cause a serious accident such as electric shock and fire three, after one month of each routine inspection equipment, it is necessary to check the equipment, pay attention to whether these anomalies power cord or plug abnormal heat, there is a burning smell. Pipe welding parts, the interface section, two quartz tube leaks. Control cabinet lights, fluorescent tubes are normal lights. Sterilization rate. Other anomalies or malfunctions. Fourth, install an ultraviolet disinfection, the device horizontally mounted indoors, the bracket or table specified by the foundation, (on the intake and outlet) position sterilization equipment in the room, in addition to considering the water up and down easily, in line with the process process requirements, but also pay attention to the mounting position leaving space to spare UV lamp, electrical control box remote equipment installed near the device, ambient relative humidity less than 40 ℃, non-corrosive gases, non-conductive dust, no severe vibration and shock. 2. Installation: This product pipeline, two outlets to choose one according to the pipeline as the inlet, an outlet, as may be required horizontal and vertical placement according to the user, in order to facilitate replacement of the lamp and quartz tube side To leave 1.6m space. After installing the first product over the water test, not leaking, then turn on the power, when the 3-5 minutes later to confirm the lamp light, hit the water valve, open the inlet valve, when the machine is running. 3. Maintenance: 1, quartz tube disassembly: Turn off the power, open the sterilizer cover both sides, remove the tube, remove both ends of the gland, remove the "O" type rubber ring seal seat inside, and then slowly Slow out of the quartz tube. 2, the quartz tube assembly: the operator do not directly touch the surface of the quartz tube, so as not to dirty the impact of transparency on the positive ends of the quartz tube water sealing position, inserted into a quartz tube, both ends of the margin to be equal, set into the "O" ring, evenly and slowly tighten the gland, the intensity is not too large, so as to avoid a quartz tube rupture, then make water test, if leakage can then gently tighten the gland, watertight up to the final Replace the lamp can be run. Five, best conditions containing fe content: less than 0.3ppm (0.3mg / L) sulfide dihydro: not more than 0.05 ppm (0.05 mg / L) suspended solids: no more than 10 ppm (10 mg / L) M content: not more than 0.5 ppm (0.5 mg / L) Water hardness: no more than 120 mg / L color: no more than 15 degrees of UV disinfection can be customized according to user needs
