A Device that Provides Cooling Capacity for Circulating Water in a Circulating Water Heat Exchanger
Due to the high temperature weather in summer,the water temperature in the circulating water is too high,resulting in poor heat transfer efficiency of the circulating water heat exchanger.In severe cases,equipment overheating and overpressure interlock shutdown accidents may occur,which is a common problem faced by the chemical industry.Tianji Coal Chemical Group,relying on its own characteristics,has developed a device that provides cooling capacity for circulating water in the circulating water heat exchanger.This device recovers the cooling capacity carried by the discharged nitrogen gas during normal operation of the air separation unit and transfers it to the circulating water on the heat exchanger,reducing the temperature of the circulating water and improving the heat transfer efficiency of the circulating water heat exchanger.It not only avoids equipment overheating and overpressure interlock shutdown accidents,ensuring the safe and stable operation of production equipment,but also turns waste into treasure,achieving the goals of rational resource allocation,energy conservation and consumption reduction,indirectly increasing the company's economic and social benefits.
