Emission reduction of construction machinery: energy saving and environmental protection

In the initial project construction and industrial fields, the pace of society quickly left our only room for survival, and some elements of this space were slowly eroded and shattered until Nature issued a sirens... Hours, energy saving is like a satellite orbiting the earth. The zero consumption of energy can converge into a huge energy pool. For many years, energy conservation and environmental protection have become a habitual topic of mankind. To protect, today, energy conservation, emission reduction, and environmental protection have entered the field of engineering construction. They have been absorbed by the construction machinery industry. Construction machinery also considers energy conservation and environmental protection as an integration, and it will take the inevitable trend of the industry in the future.

China's waste of natural resources is the most serious. Construction machinery is the second most used industry for internal combustion engine products. Although the scope of work is limited to construction sites and other areas, the emission density is high, and the emission index is worse than that of automobiles. Therefore, the pollution to the environment is even more serious. China's energy use rate is 26.9% in the United States and 11.5% in Japan. All the rest of the energy is wasted, and what is more important is that the discharged air has become the destroyer of the environment. However, the energy that is actually wasted is used in engineering construction and other fields. The value is very large. Therefore, energy saving and emission reduction not only reduces the investment in construction machinery, but also is the most direct way to reduce environmental pollution.

At present, due to the fact that the engines of old construction machinery products are mostly assembled from the time the new machine goes offline, the carbon dioxide emissions of these internal combustion engines are far higher than the industry standards that appear. Although the accessories can be replaced by new ones or replaced by new ones, the problem can be solved. However, if the replacement degree is too high, then the whole machine is equal to the replacement of the hydraulic system, and the cost is higher. Therefore, some machines that take too much time are used. It will inevitably lead to the elimination system. Although many of today's engineering machinery products have already made their debut on the market, they will be offline. However, in the future, the machine will take a long time, and the aging of parts plus the CO2 emissions of its internal combustion engines will exceed that of that time. The new standards will also be eliminated. Experts believe that companies can be encouraged to try hybrids, but this is still a way to stop the symptoms. From an environmental point of view, electricity is a clean energy source that does not generate tail gas emissions and does not exacerbate the greenhouse effect. However, the environmental issue of the battery itself should also be taken seriously. In addition, the consumption of electrical energy is much less than the consumption of general energy.

The machinery industry has also attached great importance to energy conservation and emission reduction is the need for future development. In an interview, Wang Ruixiang, president of the China Machinery Industry Federation, pointed out that the machinery industry is an important basic pillar industry in the national economy of China and bears the national economy. Various industries and major projects and defense industry construction provide important tasks for modern manufacturing equipment. Therefore, the energy saving and emission reduction work of the machinery industry is not only the internal need of structural adjustment within the industry, and the transformation of development methods, but also the realization of energy-saving products, development of energy-saving, water-saving, material-saving, and intelligent high-value-added products, which have become the realization of various industries in the national economy. The important protection of energy saving and emission reduction targets.

In 2008, the relevant organizations organized the "Recommended Catalogue of Energy-saving Electromechanical Equipment Products" and the "Elimination Catalogue of High-energy-consuming Backward Mechanical and Electrical Products". In 2009, the first “Catalogue of Elimination of High-Energy Discarded Electromechanical Equipment Products” and “Recommended Catalogue of Energy-saving Electromechanical Equipment (Products) (First Batch)” were published, involving a total of 35 categories of equipment (products). Among them, there are 7 items of internal combustion engines, 7 items of industrial boilers, 4 items of electric motors, and 17 items of general equipment. In 2010, the "Recommended Catalogue for Energy-saving Electromechanical Equipment (Products) (Second Batch)" (Draft for Soliciting Opinions) to be issued by the Ministry of Industry and Information Technology was publicized, including 7 major industrial boilers, compressors, pumps, fans, transformers, internal combustion engines, heat treatment, etc. 59 items of equipment (products). At the same time, the second batch of "Catalogue of Elimination of High-Energy Disposal Mechanical and Electrical Products" will be released.

In the “Twelfth Five-year Plan” of the target, energy conservation and emission reduction will also present an indispensable aspect in today’s society, based on its not only environmental protection, but also reduce more capital investment in the use of construction machinery to support the national policies The prospect of energy-saving and emission reduction market is not generally attractive.
