On November 25, 2010, the Ministry of Industry and Information Technology issued the Guiding Opinions on Energy Conservation and Emission Reduction of the Cement Industry. The document requires that by the end of the “Twelfth Five-Year Planâ€, cement particulate emissions should be reduced by 50% on the basis of 2009, and nitrogen oxides should be reduced by 25% on the basis of 2009. It can be seen from the document that energy saving and emission reduction is still the key point for the development of the “12th Five-Year Plan†cement industry. For cement companies, it is imperative to carry out denitrification. However, the application and popularization of denitrification in the cement industry has not yet been effectively implemented and popularized.
According to statistics, the nitrogen oxide emissions of the cement industry are the third emission portal after the thermal power generation and automobile exhaust emissions. The reduction of nitrogen oxides is not only a constraint but also a responsibility. During the "12th Five-Year Plan" period, the emission of nitrogen oxides was first included in the binding index system. Recently, the statistics released by the Ministry of Environmental Protection on the reduction of major pollutants in the first half of the year showed that in the first half of the year, chemical oxygen demand and carbon dioxide emissions continued to decline among the four major pollutants, but the new indicator ammonia nitrogen Emissions only fell by 0.73%, while nitrogen oxides emissions increased by 6.17%, which is quite different from the target of the 1.5% emission reduction for the “Twelfth Five-Year Plan†in 2011. From this data, it can be seen that at present, the targets for completing emission reduction in various industries are not optimistic. As an important member of the energy-saving and emission-reduction targets, the cement industry should consider how to use new technologies to reduce nitrogen oxide emissions.
At the 2011 Great Northwest Cement Forum recently concluded, there are cement companies suggesting that through the transformation of the kiln system, the emission of nitrogen oxides will be reduced and denitrification will be achieved. Through the exchanges with these companies, we learned that at present, how the cement industry implements denitrification technology is the focus of current cement companies. “In fact, many cement companies have been consulting China Cement Net about denitrification technologies in the cement industry and how to reduce the cost of denitrification while reducing nitrogen oxide emissionsâ€. It can be seen that at present, cement companies have turned from technical concerns to practical implementation on the issue of denitrification, but there are still many confusions and problems in the process of transformation. The 4th (2011) China Cement Environmental Protection Conference and the cement denitrification and dust collection seminar to be held in Xiamen on October 29th also formally changed from traditional emission reduction to emission reduction tasks in the new era: “This is not only a Instead of paying attention to traditional dust emission reduction, we will focus on the new phase of nitrogen oxide emission reduction, which is the most concerned and most urgently needed for current enterprises to understand. At the same time, we In various fields such as government, associations, enterprises, and equipment manufacturers, experts and scholars denitrification in the cement industry have been invited to participate in this meeting to exchange ideas and discussions,†said Shao Jun, CEO of China Cement Network.
Talking about the purpose of this conference and the expectations of this conference, Shao said: “As entrepreneurs and industry representatives, we have the responsibility to understand the latest technologies for nitrogen reduction and denitrification in the industry. I also hope to pass the media platform of China Cement Network. , To better disseminate the latest technology and ideas, policies and trends of denitrification to various cement companies, help enterprises reduce the emission of nitrogen oxides, realize the environmental protection tasks of the cement industry in the new era, and make the cement industry truly become a social responsibility and focus on social benefits. New modern industry with common development of economic benefits and business benefits."
According to the reporter’s understanding, up until now, the cement industry has not held a special conference on denitrification. Therefore, this conference can be said to be a historic conference and a new starting point. In addition, in addition to denitrification technology, the conference will continue to discuss the in-depth application of dust removal technology in the cement industry. Shao Jun told reporters that at that time, the topic of electric bag reform (electric dust bag changer to bag filter) would be another highlight of this conference.
