Waste heat recovery type distributed energy and ocean thermal energy coupling power generation system

Abstract

A waste heat recovery type distributed energy and ocean thermal energy coupling power generation system comprises a waste heat recovery type distributed energy subsystem, an absorption heat pump subsystem and an ocean thermal energy conversion subsystem. An absorption heat pump is driven by the high temperature steam and flue gas condensation heat produced by a gas turbine and a waste heat boiler which is connected with the gas turbine, the ocean surface warm seawater is heated and warmed through an absorber, a condenser and a gas and water heat exchanger of the absorption heat pump to improve the volume expansion coefficient of a low boiling point of working medium, and heat absorption and cooling are performed on the ocean bottom cold seawater through an evaporator of the absorption heat pump to improve the condensing effect on the steam exhaust of the working medium. According to the waste heat recovery type distributed energy and ocean thermal energy coupling power generation system, the full utilization of the waste heat of the distributed energy system is achieved, the running of the absorption heat pump is driven by the waste heat of the gas turbine, and accordingly the utilization efficiency of the primary energy is improved and meanwhile the temperature difference of the seawater is increased and accordingly the efficiency of ocean thermal energy conversion is improved.

Description

technical field [0001] The invention relates to a waste heat recovery distributed energy and ocean temperature difference energy coupled power generation system. Background technique [0002] With the increase of power demand and the aggravation of energy crisis, adjusting energy structure, improving energy utilization rate and solving environmental pollution have become the strategic focus of my country's energy development. With the continuous improvement of environmental protection standards, thermal power generation is not only facing the pressure of desulfurization and denitrification, but also the construction of thermal power units in key areas such as the Yangtze River Delta, Pearl River Delta, and Beijing-Tianjin-Hebei has gradually been restricted. It is imminent for the eastern coastal areas to actively develop new power generation technologies. [0003] Ocean energy is a clean and non-polluting renewable energy with abundant reserves. The ocean is the largest s...
