Example Embodiment

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] As shown in the accompanying drawings, a system equipment for heating a building in a power plant of the present invention includes traditional equipment parts: a steam extraction supply pipe 1 for power supply heating, a steam extraction condensate pipe 2 for heating power plant, and a steam-water heat exchanger 3 , Heating water supply pipe 4, end heat user 6, heating return pipe 5. The hot water at about 110° C. flowing out from the steam-water heat exchanger 3 reaches the end heat user 6 through the heating water supply pipe 4 . In the traditional heating system, the end heat user 6 is connected to the steam-water heat exchanger 3 through the heating return pipe 5, and is connected to the heat energy transfer connection with the extraction steam condensate pipe for heating of the power plant.

Abstract

The invention relates to a system device suitable for a thermal power plant and a nuclear power plant to supply heat to buildings. A thermal compensation system and a circulating water source heat pump system are connected in series on a conventional heating return water pipeline in turn, wherein the thermal compensation system introduces steam exhaust from a condenser in a power plant, and the circulating water source heat pump system introduces circulating cooling water; the circulating cooling water of the power plant is used as a low-temperature heat source and extraction stream of the power plant is used as a high-temperature heat source to form two heat sources of a heating system; and the thermal compensation system, the circulating water source heat pump system and a steam-water heat exchanger form a three-level heating mechanism of the heating system. The system device makes full use of the low-temperature heat energy in the circulating cooling water, thereby not only reducing the cost for cooling the circulating cooling water, but also reducing the extraction steam for the power plant to supply heat.

Description

technical field [0001] The invention belongs to heat supply system equipment, in particular to a heat supply system utilizing low-temperature thermal energy contained in circulating cooling water at the condenser end of thermal power plants and nuclear power plants. Background technique [0002] At present, the condensation waste heat of condensers in thermal power plants and nuclear power plants is discharged to the atmosphere or nearby waters through open or closed cycle cooling, so that the power plant wastes a lot of non-renewable primary energy and precious water resources and cause environmental pollution. How to maximize the use of existing waste heat energy and realize turning waste into wealth is one of the topics that people have been studying. Some people have proposed some technical solutions and achieved certain results, but the effect is not very satisfactory. . Contents of the invention [0003] In view of the above problems, the present invention proposes...
