SYSTEM FOR RECOVERING WASTE HEAT FROM JACKET WATER OF INTERNAL COMBUSTION ENGINE BY USING ABSORPTION HEAT TRANSFORMER

摘要

Disclosed is a system for recovering waste heat from jacket water of an internal combustion engine by using an absorption heat transformer. The system comprises a gas engine (1), an absorption heat transformer (2), a gas-fired boiler (3), a deaerator (4), a water return pipeline (5) and a soft water pipeline (6), wherein the gas engine (1) is provided with a high-temperature jacket water pipeline (7), and the high-temperature jacket water pipeline (7) is connected to the absorption heat transformer (2); the water return pipeline (5) returns water to the gas-fired boiler (3), and the soft water pipeline (6) supplies water to the gas-fired boiler (3); the water return pipeline (5) is sequentially connected to the absorption heat transformer (2) and the deaerator (4), and the soft water pipeline (6) is sequentially connected to the absorption heat transformer (2) and the deaerator (4); and the deaerator (4) is connected to the gas-fired boiler (3). The waste heat from jacket water is extracted by using the absorption heat transformer (2), thereby achieving the aims of reducing the system energy consumption and recovering waste heat to achieve energy conservation and emission reduction, avoiding energy waste, and improving the energy utilization rate.
