In November 2016, Hangli Thermal Power Combustion Coal-fired Unit 5 conducted a third-party environmental protection test by Zhejiang Environmental Testing Center and the test results met the ultra-low emission requirements of "50335". This result indicates that Hangzhou Tianming Environmental Protection Co., Ltd. completely independently developed The successful application of pulsed plasma flue gas desulphurization, denitrification, mercury removal, dust removal integrated purification technology (referred to as PPCP technology) in industrial applications, creating a precedent that the successful application of PPCP technology to achieve ultra-low emissions in China, will be China's air pollution Prevention has played a new role in promoting. Years of research, ultra-purification technology is facing bottlenecks In recent years, frequent haze in most parts of the central and eastern parts of the country has had a serious impact on the daily life and physical health of residents during the winter. For a time, smog became a hot topic in society and aroused widespread concern. Exploration of its causes, the burning of fossil fuels and sulfur dioxide, nitrogen oxides and respirable particulate matter and other pollutants emissions is the culprit haze frequent. However, in the short term, China's energy mix will remain dominated by fossil fuels and will be difficult to adjust. Therefore, the control of coal-fired enterprises to become good air quality emissions focus. During the 11th Five-Year Plan and 12th Five-Year Plan period, desulphurization and denitrification have become the key development areas of air pollution control. Countries are becoming more stringent in flue gas control standards and developing new and highly efficient integrated control technologies for multiple pollutants of flue gas The governance of air pollution is of great importance. The use of pulsed plasma flue gas desulfurization, denitrification, mercury removal, dust integration technology was the last century by the Japanese scientists in the late 80s electron beam flue gas desulfurization and denitration technology based on the proposed. 90s of the last century so far. Japan, the United States, Italy, South Korea, Canada, Russia and other countries have done a lot of research on PPCP technology. Italy took the lead in the power plant carried out 100-1000Nm3 / h of industrial tests, removal efficiency SO? 80%, NOx is 50-60%, South Korea built a maximum capacity of 50000-100000Nm3 / h flue gas treatment equipment, removal Efficiency SO? 90%, NOx 65%. In 2000, China Academy of Engineering Physics owned 20000Nm3 / h industrial test carried out by itself. The removal rate of SO? Is more than 85% and the removal rate of NOx is more than 50%. As a leading international ultra-low-emission technology, PPCP technology is of great significance to the management of air pollution. However, PPCP technology applications both at home and abroad did not exceed 100000Nm3 / h of flue gas, that is to say, the actual treatment of flue gas has not yet been achieved in large-scale power plants and industrial boilers. The main reason for this is that no high-power pulsed plasma power supply suitable for long-term reliable operation has been found. Tianming environmental protection, energy conservation emission reduction pioneer As a national high-tech enterprise specializing in air pollution control, Tianming Environmental Protection, a subsidiary of Sunyard, has been devoting itself to the development and application of energy-saving and emission-reduction technologies and successfully applied the PPCP technology to ultra-low emission projects of coal-fired power plants for the first time in China on.
