The tail gas generated in waste plastic pyrolysis production has a certain calorific value. Direct emission not only causes the loss of heat energy but also reduces the resource utilization rate of overall production. How to properly collect and utilize the waste heat of tail gas is a key direction for the energy-saving optimization of solid waste treatment equipment. A standardized heat recovery structure can reuse the waste heat source for a second time and optimize the production energy consumption structure. Based on the characteristics of the pyrolysis production process, Henan Yongle Group optimizes the tail gas heat recovery system of the plastic refining equipment, realizing the collection and recycling of tail gas waste heat and improving the equipment's energy-saving system.

The plastic refining equipment is equipped with a dedicated tail gas heat recovery device. Combustible tail gas generated during production is introduced into the heat recovery unit after purification treatment, fully releasing the calorific value in the tail gas and converting it into a usable heat source, providing thermal support for processes such as furnace body heating and material preheating.

The entire recovery system adopts a heat-exchange heat absorption structure with sufficient heat absorption area and a stable heat conversion rate, capable of fully extracting the effective heat in the tail gas, reducing heat loss caused by direct exhaust emission, and increasing the overall heat reuse ratio.

Tail gas heat supply can assist the equipment in constant-temperature production and reduce the continuous input of external fuel. Under continuous production conditions, it can steadily reduce production energy consumption and optimize the daily operating costs of the plant, meeting the needs of large-scale production.

The heat recovery process and the tail gas purification process are carried out simultaneously, ensuring energy-saving production while keeping tail gas treatment compliant with environmental regulations, achieving both resource utilization and compliant production without conflicts between environmental protection and energy consumption.

The mature tail gas heat recovery system makes the resource utilization structure of the plastic refining equipment more complete, alleviating production energy consumption pressure, aligning with the energy-saving development trend of the solid waste industry, and supporting the long-term operation of waste plastic resource recovery projects.
