Why does the underwater pelletizer save energy?

How to reduce the energy consumption of underwater pelletizing machines and improve the environmental pollution problem is gradually becoming a major concern. As the global petrochemical occupation is unusually rapid, the demand for granulators is rapidly increasing, the underwater granulator is getting bigger and bigger, and users are demanding more and more mechanical stability and energy-saving and cost reduction. underwater pelletizer does not use substances for basic transformation, but also all, multi-level energy-saving skills transformation, vigorously carry out underwater pelletizer using renewable energy and industrial thermal energy skills. So, how does the underwater granulator reach the effect of saving energy?

The general energy consumption of underwater pelletizer

Underwater granulator is suitable for secondary processing of granular products, through heating, kneading, kneading, using resin massage, widely used in precipitates, the most widely used in the petrochemical industry. Underwater granulator is a major consumer of energy, accounting for about 12% of the total energy consumption of China's national economy. In addition, the pollution formed by the single-screw granulator process is often the main source of environmental pollution in China, and the progress of single-screw granulator technology is closely related to the development of the entire national economy.

How does an underwater pelletizer achieve energy savings?

Energy-saving on the plastic pelletizing machines can be divided into two parts: one is the power part, and one is the heating part.

lThe power part of the energy-saving: most of the use of inverters, energy saving by saving the residual energy of the motor, for example, the actual power of the motor is 50Hz, and you actually only need 30Hz in production is enough to produce, that excess energy consumption is wasted, the inverter is to change the power output of the motor to achieve the effect of energy-saving.

Heating part of energy-saving: heating part of energy-saving is mostly used electromagnetic heater energy-saving, the energy-saving rate is about 30%-70% of the old resistance circle. Compared with resistance heating, electromagnetic heating has the following four advantages.

a. Compared to resistance heating, induction heaters have an extra layer of insulation, and the utilization rate of heat energy increases.

b. Compared to resistance heating, electromagnetic heaters act directly on the material tube heating, reducing the heat transfer heat loss.

c. Compared with resistance heating, the heating speed of the induction heater is more than a quarter faster, reducing the heating time.

d. Compared with resistance heating, and electromagnetic heater heating speed, the production efficiency is increased, so that the motor is in a saturated state so that it reduces, the high power low demand caused by the loss of electrical energy.

The above four points are the reasons why electromagnetic heaters can save up to 30%-70% of energy on plastic pelletizing machines, that is, underwater pelletizing machines to achieve energy savings.
