Ultraviolet photoion oxidation purification technology (UI0P) is a model of integrated and innovative application of environmental treatment technology. Through the effective combination of ultraviolet photolysis technology, catalytic oxidation technology, pulse corona oxidation technology, adsorption oxidation technology and air filtration technology, it can effectively remove medium and low Concentration of malodorous gas, and reduce ozone emissions, to achieve ultra-low VOCs emissions generated in the production and operation process, to achieve the harmonious integration of people and the environment. UIOP technology pays more attention to the protection of ambient air quality under the premise of focusing on the degradation of VOCs, and reduces the "side effects" produced in the process of VOCs governance, in order to achieve green emissions.
Ultraviolet catalyzed oxidation usually means that the pollutant's atomic structure changes under the excitation of ultraviolet rays. Under the action of an oxidant, it is gradually oxidized into low-molecular intermediate products, and organic pollutants eventually generate CO2 and H20.
Since the energy of short-wavelength ultraviolet photons is higher than the bond energy of the internal chemical bonds of most pollutant molecules, it can be broken directly by the action of ultraviolet photons on the molecular chemical bonds, thereby achieving the purpose of decomposition. UV photolysis purification technology adopts internationally advanced ultraviolet technology and wick development technology, selects high-quality quartz glass, electronic powder, mercury and other raw materials, and adopts ISO9001:2015 international quality system to strictly control production to ensure that UV lamp energy is concentrated at 185nm. It is possible to directly break molecular chemical bonds through photon oxidation, and then coordinate with ozone and hydroxyl radicals formed by ultraviolet bombardment of oxygen to achieve effective degradation of the full range of VOCs.
Advantages of UV photolysis technology
 
1. Ultra low cost, low energy consumption, easy to maintain and install;
 
2. It can treat a variety of VOCs organic waste gas such as benzene, toluene, xylene, non-methane total hydrocarbons, and esters;
 
3. It has obvious purification effect on VOCs organic waste gas with medium and low concentration and medium and small air volume.
 
Disadvantages of UV photolysis technology:
 
1. The engineering treatment effect of high concentration and super large air volume is not good;
 
2. There are certain requirements for pre-processing;
 
3. Regular maintenance and maintenance are required;
 
Commonly used in the treatment of low-concentration VOCs organic waste gas in spraying, baking paint, plastics, printing, food, feed, breeding, sewage plants, garbage stations and other industries. For the treatment of ultra-large air volume and high concentration exhaust gas in the medical, petrochemical and other industries, it is recommended to use traditional processes such as catalytic combustion and adsorption. When the air volume and concentration drop to a low concentration, UV photolysis can be used for collaborative treatment.
Finally, Amway's ultraviolet sensor used in UV photolysis lamps is an imported ultraviolet sensor-GUVC-T10GD-L. The ultraviolet sensor (UV sensor) GUVC-T10GD-L is a product with a large photosensitive area. The main detection wavelength range is 254nm. The sensor is packaged in a TO-46 metal casing. The area of ​​the photosensitive chip is 1.536mm². The output of the ultraviolet sensor is mainly related to the response, the sensor's photosensitive area and the light intensity, so products with a large photosensitive area can detect weak ultraviolet radiation. Mainly used in UV intensity detection and control, UV index detection. Outdoor UV index equipment, etc., can also be used for UV disinfection and UV curing to monitor UV intensity. UV flame detector, etc.
