The working principle of light cleaning is to use high-energy photons of specific wavelengths of ultraviolet (UV) and vacuum ultraviolet (VUV) to cut off the polymer chains of organic pollutants (such as oil, fingerprints, etc.), and generate odorous O3 under VUV irradiation. It releases active oxygen atoms; it has a strong oxidizing property, and it oxidizes the broken polymer to generate co, CO2, H2O gasification, and is discharged with the exhaust system to achieve the characteristics of dry method, no residue, and high cleanliness. . The features of this project are:
1. High-intensity UV/VUV special ultraviolet light source, adopts high transmittance to VUV, low-hydroxyl quartz tube, and adopts serpentine tube to increase the positive column area. Adopt special gas and filler comparison and temperature controllable cold point, adopt high tube wall load design and cold point controllable technology to ensure high strength and constant temperature characteristics;
2.Research and develop vacuum ultraviolet spectrometers for VUV (including UV) to ensure the test requirements of light source characteristics and material characteristics, which is an important technical guarantee for research and development of light sources;
3.System use temperature, pressure.
4.Various sensors such as concentration, ultraviolet illuminance, controllable valves, temperature controller and transmission system are integrated and optimally controlled by a microprocessor to make the photochemical reaction atmosphere in the best state;
5.The system adopts an independent self-purification closed-loop system. The pressure of each point of the system is controlled by the microprocessor to ensure that the internal Q does not leak: external dust does not enter, and the cleanliness of the internal clean room is higher than that of the external environment (referring to the workshop or the studio where the equipment is located) Completely solve the problem of the online opening system Internal equivalent closed working conditions;
6.Adopt advanced Q exhaust gas treatment technology, photothermal composite treatment technology of UV irradiation and auxiliary heating method. And set aside the interface for comprehensive utilization of Q exhaust gas.
