Nuclear energy and photoelectricity coupling steam supply system

Abstract

The invention relates to the technical field of coupling steam supply systems, in particular to a nuclear energy and photoelectricity coupling steam supply system. The nuclear energy and photoelectricity coupling steam supply system comprises a reactor, a first heat exchanger and a steam demand end, wherein a head pipeline is connected with the reactor and the reactor side of the first heat exchanger, and a reactor coolant pump is arranged on a coolant cold section of the head pipeline to form a first loop; the nuclear energy and photoelectricity coupling steam supply system further comprises a second heat exchanger, wherein the reactor side of the second heat exchanger is connected with the steam side of the first heat exchanger through an intermediate loop pipeline to form a second loop, an intermediate loop circulating pump is arranged on an intermediate loop cold section of the intermediate loop pipeline, and a heat exchange section of a tail pipeline is located on the steam side in the second heat exchanger; a water inlet section of the tail pipeline is connected with a water supply system, and a low-temperature steam output section of the tail pipeline is connected with the steam demand end to form a third loop. According to the nuclear energy and photoelectricity coupling steam supply system, compared with the prior art, coupling steam supply of the nuclear energy and the new energy is achieved; the second loop is added to isolate leakage of a reactor coolant loop, so that the situation that radioactivity of the first loop leaks to a user side is avoided.

Description

technical field [0001] The invention relates to the technical field of coupled steam supply systems, in particular to a nuclear energy and photoelectric coupled steam supply system. Background technique [0002] Industrial production requires a large amount of steam. Fossil energy is an important source of steam, such as steam extraction for thermal power units or steam supply from self-provided boilers to provide steam for industrial users. The use of fossil energy will inevitably produce carbon oxide emissions, which will have an impact on the environment. Under the background of "carbon neutrality", carbon emission reduction will become the focus of more attention. Clean energy is a very important and direct means of reducing carbon emissions, but it cannot be widely used to provide stable high-temperature and stable industrial steam. As a clean, efficient and stable energy source, nuclear energy can continuously provide users with heat. [0003] At present, the safe an...
