Heat exchange medium, heat exchange system and nuclear reactor system

Abstract

The invention provides a heat exchange medium which comprises solid particles and fluid. The invention further provides a heat exchange system which comprises the heat exchange medium, a first heat exchanger, a mixing device, a separating device, a second heat exchanger and a first conveying device, wherein the mixing device is arranged on the upstream of the first heat exchanger and used for mixing the solid particles of the heat exchange medium and conveying the mixture to the first heat exchanger; the separating device is arranged at the downstream of the first heat exchanger and used for separating the solid particles and the fluid of the heat exchange medium discharged from the first heat exchanger; and the first conveying device is used for conveying the solid particles separated by using the separating device into the mixing device after passing through the second heat exchanger. Furthermore, the invention further provides a nuclear reactor system comprising the heat exchange system. The gas-solid or liquid-solid cooling medium provided by the invention has the advantages of high thermal capacity, low-pressure system, no corrosion, off-line processing and the like. The fission reactor provided by the invention can safely and reliably operate under the high power density or ultrahigh power density.

Description

technical field [0001] The invention relates to a heat exchange medium, a heat exchange system and a nuclear reactor system. Background technique [0002] Reactors typically use water, gas or liquid metal / molten salt as the cooling medium. [0003] For ultrafast neutron spectrum and extremely high power applications, effective and safe heat transfer has always been a key issue in design. In an environment with high heat flux density, how to timely and effectively export heat through the heat exchange medium, maintain the safe and stable operation of the system, and reduce the requirements for structural materials in the design has always been the main goal of reactor design. Contents of the invention [0004] The object of the present invention is to provide a heat exchange medium, a heat exchange system and a nuclear reactor system, which can significantly improve the heat exchange effect and solve the problem of heat export at high temperature and high heat density. ...
