Recently, the Ministry of Industry and Information Technology released the national industrial energy-saving diagnostic service task in 2022, and organized nearly 150 industrial energy-saving diagnostic service agencies to carry out comprehensive energy-saving diagnosis for 124 key enterprises and 1,187 "specialized, specialized and new" small and medium-sized enterprises to carry out special energy-saving diagnosis.
A relevant person in charge of the Ministry of Industry and Information Technology introduced in an interview with People's Daily that in 2022, the industrial energy-saving diagnosis service will carry out comprehensive energy-saving diagnosis for hundreds of representative industries such as steel, petrochemical, building materials, non-ferrous metals, and key enterprises in the fields of data centers, communication base stations, etc., guide enterprises to increase investment in energy conservation and efficiency improvement, accurately implement technological transformation and management improvement, and create a number of industrial energy-saving demonstration projects and typical cases; help thousands of "specialized and innovative" small and medium-sized enterprises with large energy consumption to evaluate the energy efficiency level and actual operation of energy consumption systems and key equipment, improve energy consumption behavior, reduce energy production costs, and improve economic benefits.
"Government + Enterprise + Institution"The industrial energy-saving diagnostic service system was initially established my country's industrial field has a large number of energy-consuming enterprises and a wide range of areas. Industry experts say that accelerating the promotion of industrial energy conservation and efficiency improvement will not only help improve the efficiency of enterprises' energy resource utilization and reduce energy costs, but also promote the renewal of process flows and production equipment in key industries and fields, and enhance the industry's green and low-carbon development level. However, due to factors such as insufficient technical strength and incomplete management system, there is a large gap in the energy efficiency levels of enterprises between different regions and industries, especially small and medium-sized enterprises. The need to further save energy and reduce costs and increase efficiency is very urgent. In order to meet the energy-saving needs of enterprises, support enterprises to tap into energy-saving potential, continuously improve industrial energy efficiency, and promote green industrial development, in May 2019, the Ministry of Industry and Information Technology issued the "Industrial Energy-Saving Diagnostic Service Action Plan" to innovate the industrial energy-saving diagnostic service action. "Industrial energy conservation diagnosis is an effective method and means to promote the improvement of industrial energy efficiency, and it is also the 'key first step' for enterprises to move towards energy conservation and consumption reduction." A relevant person in charge of the Ministry of Industry and Information Technology introduced that just like a doctor treats patients, industrial energy conservation diagnosis is also a professional institution "doctors" to "take the pulse" for enterprises: industrial energy conservation diagnosis service agencies conduct comprehensive diagnosis of enterprise process technology equipment, energy utilization efficiency, and energy management system in accordance with the process of "formulating work plans - reviewing materials and data collection - on-site review of account forms and production equipment monitoring - finding the potential for saving, putting forward energy conservation opinions - tracking and transformation efficiency", and then finding out weak links and prominent problems in energy utilization, and then "symptomatic measures" to help enterprises improve energy efficiency and energy conservation management.
According to statistics, as of 2022, 19,000 enterprises across the country have received energy-saving diagnosis, and more than 600 industrial energy-saving diagnostic service agencies have issued about 37,000 "diagnostics" for energy-saving transformation measures, and it is expected to save about 66.59 million tons of standard coal, equivalent to reducing carbon dioxide emissions by about 170 million tons.
"Diagnosis service + transformation and upgrading"One-stop service helps enterprises save energy and achieve practical results The realization of achievements is inseparable from the active cooperation of enterprises and the strong support of local governments, and even more so from the active participation of industrial energy-saving diagnostic service agencies. They explain energy-saving and efficiency-improving policies, standards, technologies, and exchange cases to enterprises, provide enterprises with "one-stop" comprehensive energy services such as energy-saving diagnosis, financing, transformation and contract energy management, and help enterprises turn energy-saving opinions written on the "diagnosis" one by one into transformation practices on the production line. Through the industrial energy-saving diagnostic services carried out by Guangzhou Saibao Certification Center Service Co., Ltd. for Yunan Hongyun Cement Co., Ltd., the company successfully completed the renovation projects such as "roller press + ball mill combined with cement grinding technology, vertical grinding from grinding grid wheel to rotor scale, kiln head waste heat boiler". The project investment was 300,000 yuan, and the actual electricity saving after the renovation was 18 million kWh/year, equivalent to about 2,212 tons of standard coal per year. Chen Chunyan, director of the Ministry of Climate and Energy of Guangzhou Saipao Certification Center Service Co., Ltd., said: "Since 2019, we have provided energy-saving diagnostic services to more than 300 companies. Through this work, we have more opportunities to directly serve enterprises' energy conservation, face the pain points and difficulties of industrial enterprises' energy conservation and green and low-carbon transformation, and give them advice." After implementing energy-saving diagnostic services for Inner Mongolia Xindamao Rare Earth Co., Ltd., Guorun Venture Capital (Beijing) Technology Co., Ltd., recommended that enterprises adopt adiabatic evaporation dilute acid washing and closing cycle technology, and the washing process adopts a three-level washing + double-alkali desulfurization + secondary electromisteretic defogging process flow. The company adopted the diagnostic suggestions and implemented the renovation project, with a total investment of 20 million yuan. After the transformation, the annual waste heat available to the enterprise is 26393GJ, which is 900tce of standard coal, and can recover 15,000 tons of dilute sulfuric acid and 3,330 tons of solid fluoride salt, and accounting economic benefits of more than 18 million yuan. After Fangyuan Mark Certification Group Co., Ltd. implemented energy-saving diagnosis of Tang Changchun Third Thermal Power Plant, the company implemented the use of waste heat of heat pumps for energy-saving transformation projects, with a total investment of 120 million yuan. After it is put into operation, the direct economic benefits brought by coal saving are 8.1562 million yuan, the new heating capacity brings economic benefits of 16.5 million yuan, and the water saving benefits of 747,200 yuan, and the total economic benefits can reach 25.4034 million yuan each year.
"Industrial energy conservation diagnosis is a systematic energy-saving and carbon reduction service. We start from the aspects of enterprise energy utilization, energy efficiency, energy management, etc. to discover enterprise energy consumption problems and tap the enterprise energy conservation potential. At the same time, we actively carry out improvements in our own capabilities and build a high-level energy-saving service diagnosis team in four years, laying a solid foundation for the next step of industrial energy conservation and carbon reduction business development." Li Wei, general manager of Guorun Venture Capital (Beijing) Technology Co., Ltd., said.
"Big Data + Industry Self-Discipline"Promote diagnostic services to be "quantity" and "quality" In order to help industrial and informatization authorities at all levels grasp the progress of their work in a timely manner, and do a good job in summarizing industrial energy-saving diagnostic data, feedback of results, and acceptance of results, under the guidance of the Energy Saving and Comprehensive Utilization Department of the Ministry of Industry and Information Technology, the Fifth Institute of Electronics of the Ministry of Industry and Information Technology relies on the green manufacturing public service platform to build an online industrial energy-saving diagnostic platform as an innovative carrier for energy-saving diagnostics. The above-mentioned person in charge said that the "big data + industry self-discipline" service model is innovated, and industrial energy-saving diagnostic service agencies are encouraged to carry out self-declarations on the platform, and actively disclose relevant information such as corporate qualifications, service fields, evaluation experiences, etc. While displaying their capabilities, the institutions are also accepting social supervision, thus creating a good atmosphere for the orderly development of industrial energy-saving diagnostic work. "The self-declaration through the industrial energy-saving diagnostic service platform has increased our opportunity to interact with enterprises. We also accept supervision from all walks of life in this way." Li Chen, general manager of the Green Low Carbon Business Department of Fangyuan Mark Certification Group Co., Ltd., said. The person in charge revealed that the number of self-declaration service agencies on the industrial energy-saving diagnostic service platform increased from 210 in 2019 to more than 660 in 2022, not only achieved a "quantity" growth, but also a "quality" leap. A large number of industrial energy-saving diagnostic service agencies with high professionalism, strong service capabilities and good enterprise recognition are emerging. The industrial energy-saving diagnostic service system combining government + enterprise + service institutions + platform, a combination of public welfare and marketization has been initially established. Industry is one of the key areas of my country's energy consumption and carbon dioxide emissions. With the deepening of the "dual carbon" strategy, energy conservation, consumption reduction, cost reduction and efficiency improvement must be accelerated. "In the future, the innovative carrier represented by the industrial energy-saving diagnostic service platform will work with more industrial energy-saving diagnostic service agencies to comprehensively and deeply promote industrial energy-saving and efficiency improvement in various industries, large, medium and small enterprises, so that the "green" of the industry will be in depth and become a distinctive background for high-quality development."
