Liu Bingjiang, director of the Department of Atmospheric Environment Management of the Ministry of Environmental Protection of China, proposed at the 2017 Environmental Protection Industry Innovation and Development Conference held in Beijing on the 13th that the use of loose coal is a weak link in China's current air pollution control and one of the causes of frequent heavy pollution in winter. It is necessary to promote the pollution control of loose coal combustion and accelerate the adjustment of energy structure. Liu Bingjiang said that air pollution prevention and control must first strengthen the upgrading and upgrading of industrial enterprises' sewage facilities. In recent years, the Ministry of Environmental Protection released thermal power, coke, steel, iron, cement and other key industries 35 air pollutant emission standards, the next step will be the implementation of upgrading pollution control metallurgy, building materials, three coal-fired boilers and other key industries. The pollution control of unorganized emissions will be comprehensively strengthened, and targeted unorganized emission control measures will be proposed to promote the overall improvement of environmental quality. Second, we must strengthen the comprehensive management of pollutants. Volatile organic compounds are precursors for the formation of PM2.5 and ozone pollution. At present, China's volatile organic compounds and other pollutants have large emissions and complex sources, which is a weak link in the current air pollution prevention and control work. Strengthen the comprehensive management of areas with heavy air pollution such as Beijing-Tianjin-Hebei, Yangtze River Delta, and Shaanxi Guandong, strengthen management of key industries, implement source control, and reduce pollutant emissions. At the same time, promote the pollution control of loose coal and accelerate the adjustment of energy structure. The use of loose coal is a weak link in the current air pollution control, and it is one of the reasons for the frequent occurrence of heavy pollution in winter. Last year, the Beijing-Tianjin-Hebei region completed the replacement of 200,000 tons of loose coal with electricity for coal and gas to replace 800,000 tons of coal, accounting for 5% of the region's 40 million tons of loose coal. This year, it will complete 3 million households with electricity to replace coal and gas to replace 8 million tons of loose coal. Liu Bingjiang said that considering the current economic and social conditions, for areas that do not have a clean energy alternative, transitional measures such as replacement of high-quality coal and use of energy-saving and environmentally-friendly stoves can be adopted to replace inferior loose coal by using high-quality briquette and civil coke . To reduce pollution emissions. Liu Bingjiang said that it will strengthen the prevention and control of non-point source pollution and strictly control the pollution emissions of motor vehicles. The number of motor vehicles in Beijing, Tianjin and Hebei and surrounding areas accounts for about 30% of the country's total. It is necessary to comprehensively strengthen motor vehicle supervision. The environmental protection department will focus on increasing the pollution control of taxis with long mileage, light-duty vehicles with long service life, and heavy-duty diesel vehicles with high intensity. Liu Bingjiang proposed to promote the sustainable and healthy development of the environmental protection industry, accelerate industrial innovation, improve the technological innovation capability of the environmental protection industry, and expect the active participation of everyone in the air pollution control to jointly fight the blue sky.
Aluminum Casting Mold Design
product and mold designers can work through most of the manufacturing issues in advance by teaming up in the early stages of product development as one engineered process. ... Part design shouldn't be a millstone of the product designer , but the shared production of the entire team that has contributed to its achievement.
