Electrodeless Lamp in pollution control management application 2013-3-7

The degradation of pollutants of energy-saving lamps mainly through the following mechanism:
(1) pollutants absorbed directly by the ultraviolet radiation energy happen off key, (2) reaction system existing oxygen molecules, such as water vapor absorption of ultraviolet radiation produced O, OH and free radical oxidation pollutants; (3) electrodeless lamp excitation mode, such as DBD plasma or microwave synergy. This process can be called high oxidation (advanced ox idation process, AOPs). Through the above three kinds of mechanism of pollutants removal or to generate more easily degradable material, and then through the subsequent processing to remove. Air, water and food sterilization disinfection currently used for sterilization of energy-saving lamps mainly microwave electrodeless lamp. Microwave can make the cell polarity material with high frequency microwave field oscillating interference and obstacles, cause microbial cell protein, nucleic acid and other biological macromolecules heat setting or degeneration inactivation, leading to the mutation or death. Ultraviolet will cause microbial cells within the nucleic acid, especially DNA happen photochemical reaction, thus modified inactivation. And microwave promise UV lamp is the integration of the above two kinds of sterilization ways of advantages, so microwave promise UV lamp can be used for air, drinking water and food sterilization disinfection. By microwave excitation part of less than 200 nm wavelength of the radiation and air oxygen reaction generated ozone (O3), so that MW/UV/O3 synergy system has greatly increased the sterilization effect. Because through UV lamp has applied circuit, cannot be directly applied in drinking water disinfection, and microwave electrodeless lamp with no electrode, overcome the defect. At the same time, microwave promise ultraviolet light because the unit length of light energy output is the limit (common ultraviolet lamp limit in 30 w/m), can be arbitrary shape, diameter and length, and widened the scope of its use. 3
