On September 19-20, 2019, the third seminar on ultra-low emission control technology for flue gas in the steel and coking industry was held in Beijing. Relevant personnel from iron and steel enterprises, universities, scientific research institutions and engineering technology suppliers in the field of domestic flue gas emission control technology attended the meeting.
The conference focused on how to carry out research on how to carry out ultra-low emission upgrading and transformation, ultra-low emission transformation priorities and difficulties, how to choose technical routes, feasible technical solutions and measures.
Zhang Yuanhang, an academician of the Chinese Academy of Engineering and a professor at the School of Environmental Science and Engineering at Peking University, gave a keynote speech entitled “The Status and Trends of Atmospheric Pollution Prevention and Control Technology.” He mainly introduced the basic understanding of the state of the art of air pollution prevention and control, the overall situation of the evolution characteristics of environmental air quality, the strategic demand of beautiful China for the atmospheric sub-field, and said that only green technology innovation can support the construction of beautiful China.
Hou Li’an, academician of the Chinese Academy of Engineering and director of the Rocket Army Logistics Science and Technology Research Institute, delivered a keynote report entitled “Air Pollution Control of Industrial Plants in Healthy China”, summarizing the concept of healthy China and introducing the air of industrial plants, especially steel industrial plants. Pollution status and treatment methods, and recommendations for air quality control in industrial plants.
The former vice president and researcher of the Chinese Academy of Environmental Sciences, Chai Fa, collaborated on a keynote report entitled “Integrated Prevention and Control of Air Pollution in the Iron and Steel and Coking Industry”. He emphasized the development situation of “2+26” urban environmental protection, the three-year action plan to win the blue sky defense war and the “Opinions on Promoting the Implementation of Ultra-low Emissions in the Steel Industry”, and analyzed the typical steel city autumn and winter p182 in 2018-2019. .5 component characteristics, pointed out the need to implement smart monitoring, strengthen supervision and other measures.
Li Jianxin, Dean of the Iron and Steel Research Institute of Hegang Group, made a keynote report “Hegang Group’s Green Manufacturing Concept Innovation and Technology Practice”. He highlighted the development of five green technologies: 1) Source and process sulfur based on blast furnace charge structure optimization Nitrogen reduction technology; 2) flue gas selective circulation coupling active coke desulfurization and denitration technology; 3) coke oven gas hydrogen production and hydrogen energy industry chain extension technology; 4) Hegang typical production line intelligent manufacturing technology; 5) greening, Intelligent, branded, next-generation process steel mill.
Zhu Tingyu, a researcher at the Institute of Process Engineering at the Chinese Academy of Sciences, mainly introduced the application of ultra-low emission technology for the entire process of steel, and made some suggestions for the current ultra-low emissions. He pointed out that high-concentration CO purification of sintering flue gas, VOCs purification of coking process, fine desulfurization of blast furnace gas, deep purification of flue gas by short process electric furnace, and flue gas purification of blast furnace hot rolling furnace/rolling steel heat treatment furnace are the future development trend of steel atmospheric environmental protection technology.
Liu Jianguo, deputy dean and researcher of Hefei Institute of Material Science, Chinese Academy of Sciences, Xing Wei, dean of the School of Energy and Environmental Engineering, University of Science and Technology Beijing, and Wang Zifa, a researcher at the Institute of Atmospheric Physics, Chinese Academy of Sciences, respectively “Program”, “Research and Practice on Hot Issues of Ultra-low Emission Technology in the Iron and Steel Industry”, and “Design and Application of Control and Platform for Key Industries in Joint Atmospheric Environment Joint Prevention and Control”.
In addition, the conference set up 10 special sessions, which are the sub-site of pollutant emission reduction and energy-saving coupling technology; the sintering (pellet) flue gas denitration technology sub-site; the coke oven flue gas pollutant control technology sub-site; steel Fine particulate ultra-low emission technology and system energy saving sub-site; multi-pollutant ultra-low emission control technology sub-site; pollutant monitoring technology sub-site; steel coking industry pollution control and cost-effective simulation technology sub-site; steel, coking industry toxic and harmful atmosphere Pollutant emission and control sub-site; steel and coking industry carbon dioxide emission reduction technology sub-site; steel industry air pollutant emission inventory sub-site.
In addition, the conference also held a high-level seminar on ultra-low emission in the steel and coking industries, and organized the exhibition of scientific and technological achievements and the match of enterprise demand, and the exhibition of environmental protection scientific and technological achievements.
