    Electric change bag dust removal is imperative

    Core Tip: Reducing fine particulate matter is the key to controlling atmospheric soot emissions from the cement industry. Active control from the source of sewage is the fundamental method to cope with the dual pressures of enterprise survival and ecological protection. Among them, the electric change bag is one of the current * effective technical measures.Reducing fine particulate matter is the key to controlling atmospheric soot emissions in the cement industry. Active control from the source of sewage is the fundamental method to cope with the dual pressures of enterprise survival and ecological protection. Among them, the electric change bag is one of the current * effective technical measures. The industry believes that bag dust removal technology instead of electric dust removal is the path of dust removal in the cement industry. Not only that, bag dust removal will provide technical support for * strict environmental standards, and is the main force to reduce atmospheric pollutant emissions.Before and after the heavy snow festival, the haze weather once again enveloped many parts of China. In the face of the increasingly smoggy weather, how should people deal with it? How do you get rid of the hats of big polluters?Dust removal is a priorityIn 2012, the world's total cement output was about 3.9 billion tons, and China's cement production and sales reached 2.184 billion tons, accounting for 55% of the world total. As of the end of last year, there were 1,637 clinker production lines nationwide, including 1,257 clinker production lines with a daily output of over 2,000 tons. After years of transformation and development, the cement industry has achieved good results in eliminating backward production capacity, pollutant treatment, and waste heat power generation.Jiang Minglin, a counselor of the State Council Counselor and former deputy director of the State Building Materials Bureau, believes that although the cement industry is at the forefront of the industrial sector in terms of integration, we should see that the cement industry is still a high-consumption and high-emissions industry. The process of production is determined by the process. According to 2010 statistics, the total energy consumption of the cement industry accounts for 5% of the country's total energy consumption, and dust accounts for 31.7% of the country's total industrial production emissions. Such huge energy consumption and pollutant emissions are given to the national economy. The sustainable development and ecological environment bring great pressure. Vigorously promoting scientific and technological innovation and promoting technological progress in production technology and equipment are fundamental to doing a good job in cement environmental protection.The national smog weather has pushed the pollution problem of cement companies to the cusp of public opinion. "For many years, the cement industry has always been synonymous with the 'dirty mess' in the eyes of ordinary people. The smoggy weather this year has made the image of the cement industry even worse." Gao Changming, consultant of the China Cement Association, pointed out that "China's unit land area emissions The amount of cement soot is 8.45 times the world average, and it is also the highest in the national industrial industry."Gao Changming once introduced a “two 2.5%” experience: “The dust generated in the cement plant production process accounts for 2.5% of the clinker production, and the weight lost during the transportation process accounts for 2.5% of the clinker production. The development of concrete and the increase in cement bulk rate, the latter data has declined, but the previous 2.5% is still ubiquitous."

    Detailed contract energy management

    EPC (Energy Performance Contracting): Energy-saving service company (ESCO) and energy-using units agree on energy-saving targets for energy-saving projects in contract form. Energy-saving service companies provide necessary services to energy-using units to achieve energy-saving goals. The unit pays the energy-saving service company's investment and its reasonable profit energy-saving service mechanism with energy-saving benefits. In the past, it was widely called EMC in China (this is the old name, and it has been in line with international standards in the national standards of **, called EPC-Energy Performance Contracting). This marketization mechanism began to develop in western developed countries in the 1970s. A new energy-saving mechanism based on market operation. The essence is the energy-saving business method of paying the full cost of energy-saving projects with reduced energy costs. This energy-saving investment method allows customers to upgrade their plants and equipment with future energy-saving benefits to reduce operating costs; or energy-saving service companies provide energy-saving services to customers by committing to energy-saving benefits of energy-saving projects or contracting overall energy costs. The national standard for contract energy management is GB/T24915-2010 "Technical Specifications for Contract Energy Management". The state supports and encourages energy-saving service companies to carry out energy-saving services under the contract energy management mechanism, enjoying financial incentives, business tax exemption, VAT exemption and enterprises. Income tax is exempt from three reductions and three preferential policies.

    Ministry of Environmental Protection: Environmental management qualifications are completely abolished

    The Ministry of Environmental Protection issued a notice stating that "According to the requirements of the State Council's "Decision on Cancellation and Decentralization of a Batch of Administrative Approval Items", the administrative licensing item 'Environmental Protection (Pollution Governance) Facilities Operation Unit ** Qualification Recognition' that has been implemented by the Ministry of Environmental Protection has been cancelled. At the same time, it is pointed out that the environmental pollution control facilities under the responsibility of the environmental protection departments of the provinces (autonomous regions and municipalities) operate a Class B and temporary level qualification permit, which should not be further implemented and should be abolished.       Encouraging environmental protection and not setting a threshold will enable more companies to join the field of environmental governance. Industry insiders expect that "according to the spirit of the government report and the direction of the policy, the qualifications for environmental protection operations will gradually be completely eliminated. The so-called qualification certificate will become a waste paper in the future.       It is reported that ** qualification is approved by the Ministry of Environmental Protection, and the B-level and temporary qualification approval procedures are approved by the provincial environmental protection department and reported to the Ministry of Environmental Protection for the record. For the practice of different levels of qualifications being examined and approved by different levels of authorities, Zhang Yi, the president of the Shanghai Environmental Institute, said that this approval system is unreasonable. In addition, the qualification setting gives the power to rent too much space.        In addition, Zhang Yi also said that the qualification of supervision is not the same as the supervision, but the qualification is established, and the supervision is not strict. The role of qualification management is not big, just an additional approval procedure. Therefore, in the long run, the cancellation of qualifications will become a trend, and at the same time, it is necessary to strengthen the government's regulatory functions and increase the illegal costs of enterprises.        Then, after the operation qualification becomes a waste paper, how will the government manage and supervise the enterprise, and why?        The management focus after the cancellation of qualifications will be performance management. At present, performance management is widely practiced internationally, which is the development trend under the background of market economy. In the future, companies do not need to have the so-called qualifications, only need performance, and thus enter the market economy track.
