Facing severe energy and environmental challenges, China has formulated a medium- and long-term energy technology development strategy and development plan to 2020 with a comprehensive, coordinated, and sustainable scientific development concept. The formulation of this energy and environmental development strategy, It also points out the direction for the development of China's plastic granulator technology, and it is imperative to explore a new development path for plastic granulator technology. Compared with other operations in industrial and agricultural production, the task of energy saving and pollution prevention in the plastic granulator process is particularly urgent.
The operation of plastic granulator 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. Plastic granulator is also a major energy consumer in China. The energy used accounts for about 12% of the total energy consumption of the national economy. . In addition, the pollution caused by the plastic granulator process is often an important source of environmental pollution in China. The advancement of plastic granulator technology is closely related to the development of the entire national economy.
First of all, the operation of plastic granulators covers a wide range of fields, and the energy consumption of plastic granulators in China accounts for almost half of the total industrial energy consumption, reaching 12%.
Secondly, the environmental pollution caused by the plastic granulator is also quite serious. Among the most widely used types of conventional plastic granulator equipment, more than three-quarters are hot-air plastic granulators. This type of plastic granulator equipment pollutes the environment very seriously. For the plastic granulator system, it burns coal. The transformation of the furnace has become an important issue to be solved urgently. Improving the energy efficiency of the plastic granulator process and preventing and controlling environmental pollution are complementary to each other. Reducing the energy consumption of 100 million tons of standard coal can reduce the emissions of more than 64 million tons of CO2 and SO2 in China, and its environmental protection benefits are very significant.
Therefore, when exploring the new development path of plastic granulator technology, it is necessary to comprehensively consider energy efficiency, environmental protection and product quality in order to achieve comprehensive, coordinated and sustainable development. To implement the development strategy of high-efficiency and green plastic granulators, we must first take the path of resource-saving development and change the single extensive plastic granulator into a combined and intelligent plastic granulator. It is not only necessary to carry out a fundamental transformation from the plastic granulator process, but also to carry out a comprehensive and multi-level energy-saving technological transformation, and vigorously develop the plastic granulator technology that uses renewable energy and industrial waste heat. From the government level, it is necessary to establish and improve the comprehensive evaluation criteria and industry standards for plastic granulator equipment, establish macro-control and market regulation mechanisms, and accelerate the upgrading of plastic granulator technology.
