Photocatalytic technology is a green technology with important application prospects in the field of energy and environment.In order to improve the application level of UV photocatalysis technology, on January 9, 2018, sponsored by Guangdong Bright Moon Optoelectronics Technology Co., Ltd., Guangdong Environmental Protection Engineering Vocational College , South China Green Industry Innovation Alliance UV photocatalysis technology industry forum was held in Foshan Xianhu Hotel International Conference Hall was held.
Environmental Protection Bureau of Foshan City, Liang Guofu, director of pollution control, Professor Huang Haibao Sun Yat-sen University, Guangdong University of Technology Professor Liu Xiao Xuan, Professor Huang Min of Fujian Normal University, Chinese Academy of Sciences Guangzhou Institute of Energy researcher Li Xinjun, Guangdong Environmental Protection Engineering College Chen Wentao secretary, Guangdong Province Environment Deputy Secretary-General of Protection Industry Association, Chen Jinshun, Deputy Secretary General of Foshan Environmental Protection Industry Association, Wang Baosheng, Executive Director of Machinery Industry Environmental Protection Industry, Executive Director of South China Green Industry Innovation Alliance, and Professor Zhou Rongjian of Chongqing Yong Tong Environmental Engineering Co., Ltd. , Guests attended the meeting.This forum discussed the current application of UV photocatalysis hot spots, design specifications, standardization applications, explosion-proof safety, application cases, on-line monitoring and other aspects, from around the country more than 260 representatives of environmental protection enterprises attended the meeting.
At the meeting, guests and business representatives attended the conference respectively on the compilation and application of VOCs emission inventories from industrial sources, the establishment of policies and standards for air pollution control equipment, the technology of low-concentration VOCs for light oxygen and catalytic control, the manufacturing process of bright-moon light-emitting lamps Quality control, bright moon UV lamp and ballast efficient matching technology and equipment safety design, VOCs online monitoring market analysis and how to avoid plasma, RTO / RCT explosion and other security risks were discussed.
Prof. Huang Haibao from Sun Yat-sen University gave a keynote speech
Large amount of air and low concentration of VOCs pollution control is the current air pollution control in China focus and difficult! By 2020, Guangdong VOCs emission reduction in 2015 based on 18.0%; provincial key regulatory VOCs remediation task completion rate of 100 %. At the forum, Prof. Huang Haibao from Sun Yat-sen University made a keynote speech on "New Progress in Photovoltaic-Catalytic Control of Low-Concentration VOCs Technology." In his report, Professor Huang focused on the characteristics of VOCs treatment in furniture manufacturing and packaging and printing industries. Adsorption, biodegradation, catalytic combustion and other commonly used low concentration VOCs treatment technology special and defects.He pointed out that there are limitations of common processes, including high operating costs of investment, poor system stability, secondary pollution, there are security risks and other issues; especially difficult Adapt to the low concentration, the amount of wind, multi-component complex situation.Need to develop efficient, stable and reliable and universally applicable low concentration of VOCs treatment of new technologies.
Professor Huang Haibao said that the advantages of UV photolysis technology is that the room temperature conditions occur, simple, safe and reliable. The process can exist high-energy photons, photocatalytic degradation of contaminants together, high efficiency, but will produce ozone byproduct. Is a hot spot in the research of organic waste gas purification and treatment, but it has some shortcomings such as poor stability and low efficiency, etc. Therefore, we propose a new research idea of photolysis-catalysis synergistic purification technology. By combining VUV and double-effect catalytic materials, , Improve purification efficiency and eliminate ozone.
Professor Huang Hai Bao said: 'Photolysis technology to decompose low concentration of benzene, toluene and other organic matter is technically feasible, in its application, the need to consider the application of industry and waste gas conditions (concentration, humidity, composition, residence time), focus on equipment design , Consider ozone depletion and utilization.
Chongqing Yong Tong Environmental Engineering Co., Ltd. Professor Zhou Rong Jian for case sharing
At the forum, Prof. Rongrong Zhou from Chongqing Yong Tong Environmental Engineering Co., Ltd. shared the VOCS Integrated Purification Technology and Case based on Ultraviolet Photocatalytic Oxidation (PCO). Professor Zhou Rongjian put forward the '3T' technical requirement for organic waste gas treatment equipment, Of the successful cases and more than 90% removal rate won the full audience applauded Professor Zhou Rongjian said the design of organic waste gas treatment equipment needs to use the bright moon as the representative of the high-energy UV lamp, photon energy is greater than the molecular energy of organic molecules; need The catalyst (metal oxide, TiO2) doping, spraying and fixing, the calculation of catalytic oxidation efficiency, the dynamic adsorption rate of load, the relative position design of catalytic oxidation layer and adsorption layer, the exhaust emission speed and residence time are more accurately calculated; At the same time imposed self-purification system device operation and control, and redundant ozone elimination system design.
According to Professor Zhou Rongjian introduction, the use of nano-titanium dioxide catalytic oxidation + nano-adsorption 'integrated purification' technology developed from the Yong organic waste gas treatment equipment has been in Chongqing, Shanghai, leather processing, triethylamine, rubber tires, automobiles and accessories manufacturing, Automobile repair industry, home, chemical coating production industry and flexible packaging printing industry has been widely used by the testing authority, the removal rate remained stable at 90% and above.
As the organizer of the forum, Mr. Zheng Liang, Chairman of Guangdong Bright Moon Optoelectronics Technology Co., Ltd., gave a keynote report on how to standardize and standardize the design of UV photocatalytic oxidation device, how to design the process flow and make efficient use of it.
It is understood that Guangdong Bright Moon Optoelectronics Technology Co., Ltd. is a focus on the production of UV light source and industry application solutions provider, is applying for 3 patents, related to exhaust gas treatment device utility model patents more than 20. The company through the existing UV light The advantages and disadvantages of the solution technology, proposed the concept of 'UIOP technology', that is, through the integration of innovation, efficient synergistic purification to achieve a more reliable VOCs treatment technology in order to achieve green emissions.
Recently, the Ministry of Industry and Information Technology and the Ministry of Science and Technology jointly issued the "Catalog of Major Environmental Protection Technical Equipment for Encouraging Development in the People's Republic of China (2017 Edition)", in which a room temperature catalytic oxidation of organic waste gas treatment devices has been included. As an opportunity, which marks the UV photocatalytic oxidation technology will usher in the standardization, standardization, large-scale development of the spring.
