MULTI-ENERGY-FORM OUTPUT ENERGY TOWER FOR STEPWISE RECYCLING WASTE HEAT OF GAS ENGINE

摘要

A multi-energy-form output energy tower for stepwise recycling waste heat energy of a gas engine comprises: an internal combustion engine (1); a steam Rankine cycle system (2), which carries out heat exchange with high-temperature gas exhausted by the internal combustion engine (1) and enables a steam turbine (22) to expand and work; an organic Rankine cycle system (3), which carries out heat exchange with high-temperature gas and cylinder sleeve water discharged by the internal combustion engine (1), pressurized air and condensation heat in the steam Rankine cycle system (2) and enables an expander (31) to expand and work; a bromine cooling machine set (4), which enables part of cylinder sleeve water discharged by the internal combustion engine (1) to serve as a heat source of an absorption-type refrigeration system for heat exchange; and a hot water heat exchanger (5), which is in terminal connection with high-temperature gas discharged by the internal combustion engine (1) to heat domestic water. The energy tower provides a cold, heat and electricity triple generation waste heat recycling system with multiple waste heat recycling modes combined; the comprehensive energy utilization rate of the whole system is improved, and the effect of energy saving and emission reduction is achieved.
