UV ultraviolet sterilization device of catalytic reaction technology is?
process is the use of ultraviolet germicidal lamp as the core technology, the body USES the quartz glass tube, tube filled with a small amount of inert gas, but also injected tiny amounts of liquid silver, one made of tungsten electrode is at each end, coated with a layer of heated above can emission electron cathode materials.
Uv ultraviolet germicidal lamp is the basic principle of ionization current stimulate low pressure mercury vapor and make them an ultraviolet, sterilization processing.
UV ultraviolet sterilization device catalytic reaction technology guide ultraviolet photocatalytic reaction mechanism of photocatalytic oxidation reaction is more complex, some nano material composite photocatalyst, after UV radiation, can produce electron hole.
Hole has stronger on the performance of the electronic, when meet water molecules, water molecules are taken away electronic forms hydroxyl, hydroxyl group has a strong chemical activity, can destroy organic chemical bonds, achieve the goal of decomposition of pollutants.
Photocatalysis has limitations of introduction 1, photocatalysis can limit light near the surface of the catalyst, impurity molecules or ions can only can be degraded by photocatalytic surface, because of photocatalytic hydroxyl ions from produce to the demise of the time is very short.
And the principle of the ultraviolet radiation sterilization can penetrate certain water, ozone and chlorine gas can be dissolved in water, action time can reach tens of minutes;
2, photocatalytic activity is influenced by external factors, such as water in some ion optical catalytic decomposition has a promoting effect, also have some ions or molecules light catalyst poisoning.
The humidity in the air to light also has effect on the catalytic effect, and must have water molecules photocatalytic.
In the process of equipment work, photocatalytic effect is often difficult to measured and judgement;
3, measurement of photolysis factor, disinfection sterilization, for example, normally we can test disinfection factor.
Such as ultraviolet disinfection, we can test 254 nm uv intensity, chemical disinfection can test chemical factors, such as ethylene oxide, ozone concentration, and the light catalytic reaction, now can't test the so-called factors, such as. . .
OH concentration will not be able to test, simply because there is a short time, also does not have the proper test methods;
4, photocatalytic no matter in air or in water, by the efficiency of its photolysis is limited.
Can handle only a very low content of impurities of air and solution, and a longer processing time.
Such as air purification, can only be used for gas lighter pollution environment, and cannot be used for such as purification of waste gas, waste water etc.
disinfector to remove residual chlorine technology introduction of ultraviolet disinfection device can effectively destroy residual chlorine and chlorine ammonia chemical bonds, its advantage lies in the technology does not need to work to add any auxiliary agent in water, also do not need to store chemicals, easy maintenance, but also have the function of the sterilization and removal of organic matter, its unique advantages is widely used in various fields. However, germicidal uv light isn't the only producer in domestic, and many people feel that Tepro (China) Co., Ltd.'s service leaves much to be desired in terms of functionality and design. Tepro (China) Co., Ltd.’s core aim is to afford high-quality products with the concept of manufacturing technology. Tepro (China) Co., Ltd. offer various lines of products in line with international standards along with professionals who can offer suitable solutions pertaining to the existing problem in uv disinfection lamp bactericidal lamps.
