February 20, China Environmental Protection Industry Association held in Beijing organized by the Blue Sky Blue Sky Technology Co., Ltd. Huazhong University of Science and Technology, State Key Laboratory of Coal Combustion and Guodian Fengcheng Power Generation Co., Ltd. jointly completed the "fine particulate agglomeration enhanced dust removal technology" Identification meeting. Expert Committee of Identification by Tsinghua University, Zhejiang University, Beijing University of Aeronautics and Astronautics, Beijing Institute of Labor Protection, China Electricity Council, Energy Conservation and Environmental Protection Branch, China Guodian Corporation, Datang International Power Generation Co., Ltd., TianCheng TianCheng Environmental Science and Technology Co., Ltd., Xi'an Thermal Research Institute Co., Ltd. and other relevant units of academicians and experts. It has been identified that this technology is highly innovative and has reached the international advanced level in reunion and fine particle removal technologies. It is suggested to speed up its application. At the meeting, Professor Zhang Junying of Huazhong University of Science and Technology introduced the principle of the technology, research progress and economic indicators. In the technology, an agglomeration agent spraying device is added in front of the electric / bag dust remover in the post-combustion zone to spray the atomized agglomeration accelerating agent into the flue to make the fine particulates in the flue gas agglomerate into chains and flocs and adhere to the large particles , And then by electric / bag filter capture, thereby significantly increasing the removal efficiency of fine dust particles, reaching the national ultra-low emissions requirements. In terms of economy, the technology has the advantages of simple installation, no shutdown, automatic control, stable operation, simple maintenance, small occupied area, flexible installation site and low investment in construction. At the same time, industrial wastewater can be used to make agglomeration liquid to save water resources and no secondary pollution; without high power power source, no increase of wind resistance, small temperature drop of flue gas, no need of secondary heating. The expert group headed by academician Yue Guangxi of Tsinghua University reviewed the related technical documents and listened to the R & D report, technical report and user evaluation report of the R & D unit and watched the video of the technology applied by Guodian Fengcheng Power Generation Co., Ltd Discussion, that the technology to solve the problem of efficient removal of hydrophobic fine particles, the development of the fine particle agglomeration technology and large-scale application process system, combined with the existing electrostatic precipitator and wet desulfurization process can achieve ultra-low emissions of fine coal-fired power plants . And the technical achievements have been successfully applied to a number of coal-fired power plants and industrial kilns in Shanxi, Jiangxi and Hubei. The expert group believes that this technology provides a practical and cost-effective technical solution for coal-fired boilers and kilns to achieve ultra-low emission of particulate matter, and can be widely used in related industries such as thermal power, steel and cement. It is understood that after the State Power Fengcheng Power Co., Ltd. on the 4th 340,000 kilowatts units have been using the technology to complete the transformation of ultra-low emissions and successfully passed the 168-hour trial run by the Jiangxi Provincial Environmental Monitoring Station test, the average particulate emissions per cubic meter 1.7 Mg, better than the national ultra-low emission requirements. Chen Zi Li, deputy general manager of Guodian Fengcheng Power Generation Co., Ltd. introduced the overall effect of agglomeration dust removal in terms of induction. There are three main points. The first one is that it has good safety and solves the difficult problem of technological transformation due to the small size of the site and avoids many high altitude Job risk. The second is practicality, technical transformation process did not shut down, and does not change the existing operating parameters of the power plant, after the completion of technological transformation to meet the expected emission reduction requirements. The third is high economy, low investment and operating costs, simple operation and maintenance, and obvious economic benefits. An Shengli, general manager of Wuhan Sky Blue Environmental Technology Co., Ltd. introduction, the technology can effectively control emissions of PM2.5 harmful to human health, hoping to promote the application of major power generation groups in order to meet the more stringent emission standards of the country in the future Provides a cost-effective technology path.
