In the face of serious energy and environmental challenges, comprehensive, coordinated and sustainable China to Scientific Outlook on Development as the guiding ideology, formulated to 2020 long-term energy technology development strategy and development plan, the energy and environment strategy development, but also pointed out the direction for the development of China plastic granulator technology, explores a new development way for plastic granulator machine technology is imperative. It is particularly urgent to save energy and prevent pollution in the process of plastic granulator compared with other operating links in industrial and agricultural production.
Plastic pelletizer operation involves a wide range of national economy. It is not only an indispensable basic production link for a large number of industrial and agricultural products, but also a large energy consuming household in China. The energy consumption accounts for about 12% of the total energy consumption of the national economy. In addition, the pollution caused by the process of plastic granulator is often an important source of environmental pollution in China. The progress of the technology of plastic granulator is closely related to the development of the whole national economy.
First of all, plastic pelletizer operation involves a wide range of fields, and the energy consumption of China's plastic granulator accounts for almost half of the total energy consumption of the whole industry, reaching 12%. Secondly, the pollution of the plastic granulator to the environment is very serious. In the most widely used conventional plastic granulator, more than 3/4 of them are hot-air plastic pelletizer. The environmental pollution of these plastics granulator equipment is very serious. The transformation of the coal granulator system of the plastic pelletizer system has become an important topic to be solved urgently. The improvement of the energy utilization efficiency of the plastic granulator and the pollution of the environment is complementary to that of the plastic granulator. To reduce the energy consumption of 1 million tons of coal, the emission of CO2 and SO2 can be reduced by more than 64 million tons in China, and its environmental benefits are very significant.
Therefore, when exploring the new development way of plastic pelletizer technology, we must comprehensively consider the energy efficiency, environmental protection and the quality of products, so as to achieve comprehensive, coordinated and sustainable development. To implement the development strategy of high efficiency and green plastic pelletizer, first of all, we should take the resource saving development way and transform the single extensive plastic granulator into a combination and intelligent plastic pelletizer. Not only should we transform fundamentally from the technology of plastic pelletizer, but also carry out comprehensive and multi-level energy saving technology transformation, and vigorously develop the technology of plastic granulator that applies renewable energy and industrial waste heat. From the government level, we should establish and improve the comprehensive evaluation criteria and industry standards of plastic granulator equipment, establish macro control and market regulation mechanism, and speed up the upgrading of plastic granulator technology.
