Efficient electricity, heat and cooling tri-generation supply system

Abstract

The invention relates to an efficient electricity, heat and cooling tri-generation supply system. The efficient electricity, heat and cooling tri-generation supply system comprises a gas generator set, gas, a mains supply power grid, an absorptive lithium bromide refrigerator set, heat pump type centrifugal refrigerator sets, a heat storage tank, a cooling tank and a water tank. The efficient electricity, heat and cooling tri-generation supply system is characterized in that medium-temperature discharged waste heat of the gas generator set is parallelly connected into an absorber and a hot water manifold of the absorptive lithium bromide refrigerator set, burning discharged smoke of the gas generator set is connected into an SCR (selective catalytic reduction) device, a hot water pipe of the SCR device is connected into the absorber and the hot water manifold of the absorptive lithium bromide refrigerator set in parallel, low-temperature waste heat water of the gas generator set is connected with the hot water manifold, and electric power output of the gas generator set is separately connected with the mains supply power grid and the heat pump type centrifugal refrigerator sets. The efficient electricity, heat and cooling tri-generation supply system has the advantages that smoke and low-to-high-temperature waste heat of the gas generator set are recycled and all utilized, system integration energy utilization rate is ensured at 80% or above by gradient utilization of primary energy, CO2 emission is greatly reduced, and pollutants such as NOx are reduced.

Description

technical field [0001] The invention relates to a high-efficiency electric heating and cooling combined power supply system. Background technique [0002] At present, with the shortage of energy, more and more regions adopt the form of triple power supply to supply power, heat and cold to a concentrated region. It is based on the concept of energy cascade utilization, and it is a total energy system that integrates refrigeration, heating (hot water, heating) and power generation. Its biggest feature is the cascaded utilization of energy of different qualities, using the heat energy from the combustion of gas with a higher temperature for power generation, and using the low-quality heat energy with a lower temperature for cooling or heating. At present, there are many applications of triple power supply systems, and there are also many patent applications. However, some triple power supply systems currently have some unsatisfactory energy efficiency utilization, and some of ...
