Abstract

The invention relates to an energy saving system combining power plant circulating water waste heat pump utilization and cross-seasonal natural water body heat storage. The energy saving system comprises a thermal power plant heat supply origin station, a cross-seasonal natural water body system, a circulating water cooling source loss recovery system and a pipeline connection system, wherein the cross-seasonal natural water body system comprises a water storage pit, a heat storage water body, a water distributor, a water bottom protection layer, and a heat-insulating covering layer, a rainwater collecting system and a drainage system on a water body surface; the circulating water cooling source loss recovery system comprises a circulating water inlet and outlet pipeline, a steam-driven absorption heat pump and / or an electric compression heat pump, and a heat pump-driven steam pipeline and / or an electric compression heat pump power connection system. Through introducing a heat pump technology and combining a cross-seasonal natural water body in summer for heat storage, heat is stored in summer and supplied in winter, in addition, the generating capacity can be consumed by utilizing the electric compression heat pump in summer, and the on-grid energy is reduced so as to realize peak regulation in summer, so that the energy saving system not only can be used for effectively relieving renewable energy source absorption predicament, but also can realize huge-scale cross-seasonal heat storage of heat supply hot water, and is wide in prospect.

Description

technical field [0001] The invention relates to the field of recycling waste heat of circulating water in a power plant by using a heat pump, inter-seasonal energy storage and deep peak regulation of a power grid, and particularly relates to the field of utilization of waste heat of circulating water in a thermal power plant in summer and deep peak regulation of electric load in summer. Background technique [0002] During the power generation process of thermal power plants, a large amount of low-grade heat from steam turbine exhaust is discharged into the atmosphere through cooling towers or air-cooling islands, resulting in huge energy waste and obvious environmental humidity and heat impact. [0003] In addition, in China's three northern regions, the power market capacity is abundant, and peak-adjustable power sources such as gas turbines and pumped storage are scarce. Insufficient capacity and severe wind abandonment. At present, with the implementation of power ancil...
