All localities have issued documents to promote cement peak shift production and help defend the blue sky

Abstract: in general, this year's peak shift production in the cement industry in summer is running smoothly and orderly, effectively reducing the total emission of pollutants, promoting the continuous improvement of air quality, ensuring the balance between market supply and demand, and promoting the healthy and orderly development of the industry

the market demand of the cement industry decreases seasonally in summer, and cement enterprises in many parts of the country implement peak staggering production in summer under the guidance of industry associations. In general, this year's peak shift production in the cement industry in summer operated smoothly and orderly, effectively reducing the total amount of pollutant emissions, promoting the continuous improvement of air quality, ensuring the balance between market supply and demand, and promoting the healthy and orderly development of the industry

at present, the situation of China's atmospheric environment is still severe, and the emission of atmospheric pollutants is still in the forefront of the world. The prevention and control of atmospheric pollution has become a key weakness in building a well-off society in an all-round way. It is urgent to achieve continuous improvement of air quality through all-out efforts. The 19th National Congress of the Communist Party of China proposed to take the battle of pollution prevention and control as one of the three major battles to win the decisive victory in building a well-off society in an all-round way, and required to adhere to the joint governance of the whole people, source prevention and control, continue to implement air pollution prevention and control actions, and win the blue sky defense war

the overall goal of the three-year action plan for winning the blue sky defense war recently issued by the State Council is to significantly reduce the total emission of major air pollutants, cooperate to reduce greenhouse gas emissions, further significantly reduce the concentration of PM2.5, significantly reduce the days of heavy pollution, significantly improve the ambient air quality, and significantly enhance people's blue sky happiness after three years of efforts

various regions have issued documents to promote the cement industry as the main emission source of dust and nitrogen oxides. In order to reduce air pollution, according to the requirements of the State Council office, cement clinker devices in other regions should also be peak shifted production during the Spring Festival and hot summer. Many regions across the country have launched peak shifted production of cement in summer, which has been supported by local government policies and funds

the guiding opinions on the peak staggering production of cement clinker enterprises in summer 2018 issued by Shanxi Provincial Commission of economy and information technology and the provincial environmental protection department clearly states that this peak staggering production takes "the macro guidance of the government, the organization and implementation of associations, and the active participation of enterprises" as the basic principle, gives full play to the role of industry self-discipline, and consciously performs the social responsibility of enterprises; The scope of implementation covers all cement clinker production lines in the province (including special cement, excluding grinding stations).

in order to implement the spirit of the "Shaanxi iron wrist haze control and win the blue sky defense war three-year line 7.3 stress-strain curve dynamic plan (2018-2020)", and implement the requirements of the "Shaanxi iron wrist haze control and win the blue sky defense war 2018 key points", Shaanxi Cement Association, in accordance with the work arrangement of the Provincial Department of industry and information technology, Organize 10 cement clinker production enterprises in the province to collectively study the spirit of the document and arrange the peak staggering production in the summer of 2018. Among them, the cement industry in Guanzhong Region (including special cement, excluding grinding stations) implements a production limit of about 30%, which is calculated based on the design production capacity. Chen Jun, director of the raw material industry department of the Provincial Department of industry and information technology, affirmed the role played by the Provincial Cement Association in peak shift production, and put forward four requirements for peak shift production in 2018. First, we should raise awareness; The second is to maintain the healthy development of the industry; Third, we should have a sense of the overall situation; Fourth, we should strengthen inspection

in order to thoroughly implement the spirit of the "Hebei ecological gold Protection Conference" and the "Zibo Conference on the decapacity of Shanxi Hebei Shandong Henan c12+4 cement industry", and do a good job in the prevention and control of air pollution and the decapacity of cement in summer in Hebei Province, combined with the recent weather conditions, demand and power consumption in Hebei Province, Hebei Province issued the "notice on the implementation of peak staggering production in summer by cement clinker enterprises in the province"

according to the requirements of the notice on further standardizing the peak staggering production in the cement industry of the whole province (ejxjh [2018] No. 21) and the supplementary notice on the peak staggering production in the cement industry of the whole province (ejxjh [20 on its production scope 18] No. 39) issued by the Hubei Provincial Commission of economy and information technology and the Department of environmental protection, The summary table of peak shift production plan of Hubei cement enterprises in 2018 prepared by the provincial economic and Information Technology Commission in conjunction with the provincial environmental protection department clearly stipulates the respective shutdown time of 59 cement production lines. About 80% of the production lines need to be shut down for more than 60 days. The shutdown time of each kiln in the whole year is more than 70 days, and the average shutdown days of non winter peak shift are more than 30 days

according to the work plan for peak shift production in Chongqing cement industry (2018-2020) released by Chongqing Municipal Commission of economy and information technology and Environmental Protection Bureau, from now on to the end of 2020, January to February, June to August, November to December, rainy season, power peak, environmental emergency period and heavily polluted weather period of each year are peak shift production periods in the cement industry, and other months are peak shift production adjustment periods. A total of 48 new dry process cement clinker production lines and 2 JT kiln cement production lines in 33 cement enterprises in the city have all implemented peak staggering production, with a total of 4825 days of peak staggering production shutdown, with an average of 96.5 days of peak staggering production shutdown for each cement production line

in addition, from May 16, Inner Mongolia has implemented the peak staggering shutdown of the cement industry in summer and autumn, which will be stopped every month for 30 days, and the overall shutdown time in peak season is 80-100 days until the peak staggering production in winter starts; Guangdong cement enterprises shut down their kilns for 10 days from May 1 to July 31; Cement enterprises in Northeast China shut down their kilns during the peak shift from June 1 to June 15. They plan to shut down their kilns for 15 days a month from July to September

effectively reduce the emission of air pollutants

from the perspective of the environmental protection policy of providing information to enterprises for the first time today, the scope of environmental protection emission limits has been further expanded, and normalization has become the main trend. The "three-year action plan for winning the blue sky defense war" issued by the State Council recently expanded the scope of key emission limitation areas from Beijing Tianjin Hebei and its surrounding areas to the Yangtze River Delta and Fen Wei plain on the basis of "2+26" cities, that is, Shanghai, Jiangsu, Zhejiang and Anhui were included as a whole. At the same time, the number of cities involved in Hebei, Henan and Shanxi increased from 8, 7 and 4 to 9, 9 and 8 respectively, Expansion of restricted drainage area. In this context, the majority of cement enterprises actively participate in peak staggering production in summer, effectively reduce the emission of air pollutants from cement clinker production, promote energy conservation and emission reduction, improve air quality, and help win the blue sky defense war

the peak staggering production of cement in Shanxi in winter has been implemented for four years. The peak staggering production of cement in summer 2018 was first implemented by the provincial economic and Information Technology Commission and the provincial environmental protection department. At present, in terms of the comprehensive effects of capacity reduction, energy conservation and emission reduction, market supply and demand balance and economic operation quality, it is the best implementation effect of peak staggering production over the years, and has played a good demonstration effect in the cement industry in North China. According to the calculation, through the peak staggering production in this summer, Shanxi will reduce the output of cement clinker by 3.909 million tons, the consumption of coal by 450000 tons (converted into standard coal), the emission of CO2 by 3.381 million tons, the emission of SO2 by 120 tons, the emission of NOx by 4340 tons, the emission of dust by 720 tons, the storage of clinker by about 4million tons, and the occupation of working capital by enterprises by about 600million yuan. Various data show that the peak staggering production of the cement industry in the province in summer has achieved the expected goal and achieved good social, economic and environmental benefits

according to the work plan for peak staggering production in Chongqing cement industry (2018-2020) issued by Chongqing Municipal Commission of economy and information technology and Environmental Protection Bureau, the cement enterprises in the main city and Western Chongqing have a total of 110 days of peak staggering shutdown every year, including 20 days in January to February, 35 days in June to August, 20 days in November to December, and 35 days in other periods; Cement enterprises in Southeast and Northeast Chongqing (including Qijiang, Nanchuan and Wansheng Economic Development Zone) have a total of 85 days of staggering peak shutdown every year, including 15 days in January to February, 30 days in June to August, 15 days in November to December, and 25 days in other periods. After the implementation of peak shifting production, each cement production line will stop the kiln for 96.5 days on average, achieving an annual reduction of cement output of 15million tons, the use of standard coal of 1.5 million tons, the reduction of power consumption of 1.3 billion kwh, the reduction of carbon dioxide of about 1.5 million tons, the reduction of sulfur dioxide of about 50000 tons, the reduction of nitrogen oxide of about 20000 tons, and the reduction of dust of about 400000 tons

it has been four years since the implementation of peak shifting production in the cement industry in 2014. Relevant data show that peak shifting production plays an obvious role in reducing air pollution and improving air quality and environment during heavily polluted weather, which has been highly valued by the Ministry of industry and information technology, the Ministry of ecological environment and other relevant government departments. Taking Sichuan as an example, in 2017, the cement industry in Sichuan Province increased efforts to promote peak shift production. Through peak shift production, the consumption of coal was reduced by 5.19 million tons, the emission of carbon dioxide was reduced by 40.07 million tons, the emission of sulfur dioxide was reduced by 13000 tons, the emission of nitrogen oxide was reduced by 51400 tons, and the clinker output was reduced by 46.33 million tons. Then the extended plan must be followed until * vigorously later, and it was taken down to achieve both social and economic benefits. The goal of staggering peak production in Sichuan Province in 2018 is to control production capacity and output, reduce energy consumption and reduce pollutant emissions for no less than 100 days per line

relevant professionals said that peak staggering production has brought significant environmental and social benefits, and has a positive role in resolving overcapacity and improving industrial benefits. Peak staggering production has become a major measure to promote air pollution prevention and control. At present, many places in the country have started the peak staggering production in summer in the cement industry, effectively reducing the frequency of heavily polluted weather and reducing the degree of pollution. As the scope of peak staggering production continues to expand, the time is longer, and the implementation is more strict. For example, Henan Province stipulates that all cement and foundry enterprises in the province must implement the national peak staggering production requirements, and it is strictly prohibited to resume production without authorization. If the implementation is not in place, power-off measures will be implemented for production power, and its significance and effect will be further affirmed
