AI Technical Summary
When the tail gas of the coating granulation reactor is sprayed, the high temperature of the tail gas causes heat to be lost directly, making it impossible to effectively utilize the waste heat and increasing the waste of production energy.
The system employs a heat absorption mechanism and a cleaning mechanism. It uses a spiral heat pipe to absorb heat from the exhaust gas and then sprays the hot water for use in other production processes. At the same time, it uses a scraper to clean up dust, ensuring the normal operation of the equipment.
This achieves effective utilization of exhaust gas waste heat, reduces energy waste in production, and improves the availability and practicality of the equipment.
