Energy tower of multi-energy-form output for stepwise recovering waste heat of a gas engine

Abstract

A multi-energy-form output energy tower for stepwise recovering waste heat of a gas engine, comprising an internal combustion engine (), wherein the present invention also comprises a steam Rankine cycle system () which is capable of heat exchanging with the high temperature exhaust exhausted from the IC engine () to make the steam turbine () do expansion work. An organic Rankine cycle system which is respectively heat exchanged with high temperature exhaust, jacket water and charge air which are exhausted from the IC engine (), and with condensation heat in the steam Rankine cycle system () to do expansion work; a lithium bromide refrigerator () which uses jacket waterpart of jacket water discharged from the IC engine () as a heat source of the absorption cooling system for heat exchange; and a hot water heat exchanger () connected with a high temperature exhaust of the IC engine () for heating domestic water. The energy tower of the present invention adopts multiple waste heat recovering methods and combines cooling, heating and power supplying methods, which improves comprehensive energy utilization efficiency of the system and achieves the effects of energy saving and emission reduction.
