Industrial energy conservation needs to focus on the big and the small.

new industrialization, industrial green low-carbon development and industrial greening are words that appear frequently in the industrial field. Although they have different perspectives, they have the same requirements for efficient utilization of resources and energy and environmental friendliness: they must meet the requirements of the basic national policies of saving resources and protecting the environment. Energy conservation and emission reduction is the top priority of green industry. Comprehensive utilization of resources can improve resource and energy efficiency and reduce pollutant emissions, which is also the work vigorously promoted by the Ministry of industry and information technology in recent years

industrial energy conservation should focus on the big and start with the small. Focusing on the big picture is to comply with the development trend at home and abroad, give play to the role of informatization in promoting industrial energy conservation, and balance the supply and demand of commodities at home and abroad. The government should focus on the macro, carry out top-level design, and create an external environment for enterprises to actively save energy. Starting from a small place is to implement the concept of industrial greening. The department management has a grasp and grounding. The enterprise has a focus on its work, and strives to achieve industrial greening as soon as possible

it is well known that industrial energy conservation is extremely important. Different ideas, techniques and equipment are used to achieve the effect of pollutant emission reduction. Therefore, industrial energy conservation and emission reduction is a buzzword. China's energy intensity per unit of GDP is about twice that of foreign countries. Industrial added value accounts for less than 40% of GDP but consumes nearly 70% of energy. Industrial energy conservation has great potential. Improving industrial energy efficiency contributes to the realization of industrial greening, which covers both resources and environment:

first, the efficiency of resources and energy is high. Resources and energy are the key elements for the development of industry, especially in the initial stage of a region. Only by changing the way of resource utilization and improving the efficiency of resource and energy utilization can we realize the decoupling between industrial development and resource environment. Comprehensive utilization of resources, substitution of scarce resources, utilization of residual heat and pressure, energy, water, materials and all resources are important ways to improve resource efficiency

second, it is environmentally friendly and the cost of pollution is low. We should reduce the production and discharge of industrial pollutants and form a virtuous circle. At the enterprise level, this requires cleaner production, production of environmentally friendly products, reduction or substitution of production and consumption of environmentally harmful products, and reduction of risks of industrial activities to human health and the ecological environment, which is also the essential requirement of environmental friendliness

in a broad sense, industrial greening or new industrialization requires more guidance and evaluation indicators, including:

first, industrial structure. Industrial structure or industrial structure is closely related to the development stage of a country or a place. To produce products with high added value and technological content, the resource input and pollutant emission intensity are smaller than those of primary products, and more inputs of production factors such as talents, technology and capital are required. Therefore, structural upgrading is the process and direction of industrial development. Adjusting the industrial structure, optimizing the spatial layout, and strengthening the constraints of land, energy consumption, environmental protection, quality, safety and other standards are necessary measures for structural adjustment

second, innovation driven. The industrial revolution was driven by the technological revolution: the invention of the steam engine brought about the first industrial revolution, electrification promoted the second industrial revolution, and the third industrial revolution needed the boost of informatization. In other words, internet++ will play an increasingly important role in the greening of China's industry. Raw material supply, storage, transportation route optimization, technology upgrading, etc. can be optimized with the help of internet++ to achieve the purpose of improving efficiency and reducing pollutant emissions as a whole

three is the unification of three benefits. Realizing the organic unity of economic benefits, social benefits and environmental benefits is an important goal of green industry. The greening of industry requires not only the pursuit of economic benefits, profit-making of enterprises and local fiscal revenue, which is also the premise of sustainable industrial development, but also the pursuit of social benefits, which can provide more employment opportunities and promote social harmony and stability. This is also an inevitable requirement to avoid falling into the trap of medium income

industrial green 3. Transmission speed: colorization, we should thoroughly implement the general requirements of the Party Central Committee and the State Council on the construction of ecological civilization and comprehensively deepening reform, comply with the new expectations of the people for a good ecological environment, take the construction of ecological civilization and the coordinated development of industry as the goal, focus on energy conservation and emission reduction in key areas and regions, innovate ideas and development models, make use of interconnection + optimize the allocation of resources, strengthen index guidance Service support, strengthen inspection, assessment and assessment, form a long-term mechanism for industrial energy conservation and emission reduction, form an internal driving force for enterprise energy conservation and emission reduction, and make industrial energy conservation and emission reduction reach a new level

utilize interconnection + optimize the allocation of energy conservation and emission reduction resources. At the national level, the use of IOT, specialized interconnection and other tools and platforms to promote the connection between commodity supply and demand, the optimization of raw material storage and transportation routes, and the technological transformation and upgrading of industries and products are also broad-based industrial energy conservation and emission reduction measures conducive to the upgrading of industrial structure and the optimization of spatial layout

system optimization is very necessary for China's industrial energy conservation, and it is also an important measure to solve the common problem of high enterprise efficiency and low social efficiency in China. From the perspective of reality, there are objective requirements for system optimization in China from the macro to the micro level. Energy saving service companies and Internet operation companies have had a lot of practice in this regard

balance of commodity supply and demand. Commodities in short supply or in serious surplus are a great waste of resources and energy, and will also increase the pressure on environmental protection. From the micro level, energy-saving service enterprises have played a role in reducing storage, transportation costs and overstocked funds by optimizing raw material supply and material balance. From a macro perspective, forecasting the balance between supply and demand of commodities will help reduce the impact of the imbalance between supply and demand of products on prices. Strengthening the industrial chain management among industries is also a broad sense of energy conservation and emission reduction

transportation route optimization. With the development of river, highway, railway, aviation and other transportation facilities in China, the best routes for the transportation of many commodities have changed. Optimizing transportation routes according to the changing situation can not only save China's scarce oil products, but also reduce invalid transportation. Some Internet enterprises have actively explored in this regard. On the basis of connecting the information of the supplier and the demander, they can also carry out door-to-door transportation and reverse logistics to achieve the effect of energy conservation and emission reduction

optimize the production process. Unscientific process, technology, equipment and production process will consume more energy. Power, steel, cement, chemical and other process industries have the potential to achieve energy conservation and emission reduction through process optimization. Uneconomical and decentralized heating boilers and kilns can improve energy efficiency through optimized configuration and centralized heating. Some domestic energy-saving service companies, through process optimization, system optimization and other technology integration, use the Internet platform for intelligent remote management to achieve 3% to 10% energy-saving results, which should be promoted

build an energy center and a national industrial energy conservation monitoring platform. The Ministry of industry and information technology and the iron and steel industry association are vigorously promoting iron and steel enterprises to build energy centers. Practice has proved that iron and steel enterprises can save energy by 1% to 3%. Promoting the national industrial energy conservation monitoring system to automatically collect industrial energy consumption data on a monthly basis and establish a data sharing mechanism can promote national industrial energy conservation and emission reduction. This shows that the potential of industrial energy conservation and emission reduction can be realized through system optimization

reducing production or conversion processes can save energy and reduce emissions, because each process consumes energy and discharges waste. According to the investigation, the separate construction of desulfurization and denitration facilities will increase the energy consumption in the plant by more than one percent, which is tens of millions of expenses for power generation enterprises, not a one-time investment. The energy-saving and emission reduction facilities have been built into a system (integration), which has been realized technically, and should be promoted. Promoting industrial symbiosis and coupling and building a polygeneration system for energy and chemical industry can also achieve multiple goals with one stone

industrial energy conservation and emission reduction need to start with the details of energy conversion, end consumption and waste reduction. Details determine success or failure. Implement energy efficiency improvement plans for motors, boilers, internal combustion engines, etc., and improve the energy efficiency level of terminal energy consumption equipment; Carry out energy-saving technological transformation plan focusing on coking, coal chemical industry, industrial furnaces and boilers; Promote the application of revolutionary energy-saving and emission reduction technologies such as electromagnetic conversion and variable frequency speed regulation, so as to speed up the green process of industry

developing circular economy and promoting comprehensive utilization of resources can save energy and resources from the source and production process and reduce greenhouse gas emissions. Vigorously promote cogeneration and cascade utilization of energy. High temperature heat energy is used for power generation, medium temperature for driving heat pumps and refrigeration, and low temperature for domestic hot water. The iron and steel industry can achieve the effect of energy saving and emission reduction by replacing short process with long process. The proportion of scrap consumption in China is significantly lower than that in developed countries, which is determined by the lack of development stage or per capita steel accumulation. China has carried out pilot projects of circular economy in key industries such as iron and steel, nonferrous metals and electric power, and has formed distinctive development models of circular economy at the enterprise, park and regional levels. We should constantly sum up experience and promote it to improve the green level of industry

establish a long-term mechanism for green industrial development. We will give better play to the decisive role of the market mechanism and the regulatory role of the government, and establish a sound industrial green system. Strengthen the construction of laws and regulations on industrial energy conservation, water conservation and resource recycling, so as to make the greening of industry onto the track of legalization; Improve the energy efficiency standards for key products, implement the leader system, and strive to reduce the clinical efficacy of industrial P60 composite resin in filling molar occlusal caries; If it is still impossible to eliminate the fault, it is due to the unit energy consumption and pollutant emission intensity of glass ion and silver amalgam products; Use the price mechanism to promote the implementation of policies such as upward and stepped electricity and water prices for industrial waste heat and residual pressure power generation; Improve new market mechanisms such as contract energy management and voluntary agreements, and give play to the positive role of third parties in energy conservation and emission reduction; Innovate the investment and financing mechanism to attract social funds into the field of energy conservation and emission reduction; We will explore the establishment of a statistical evaluation and assessment system for green industrial development to guide green and sustainable industrial development
