Problems solved by technology

[0005] At present, there are few methods of experimental research. It is known that there are supercritical water heat exchange devices in Xi'an Jiaotong University, supercritical water natural circulation loops in Tsinghua University, and dual-channel supercritical water test benches in China Nuclear Power Research and Design Institute. However, the experimental research objects They are all supercritical water, but there is no research on the particles in supercritical water, and the detection method does not use visual measurement

Embodiment 1

[0173] An experimental device for visualized measurement of supercritical water particles, such as figure 1 As shown, it includes a preheating section, a heating section, a visual section, a cooling section, a stabilizing section and a feeding section connected in sequence through stainless steel pipes. The thickness of the stainless steel pipe is 3mm; the internal diameter is 4mm.

[0174] The preheating section is set horizontally, and there are thermometers and pressure gauges in front of it to observe the fluid flow and the pressure inside the pipeline; the preheating section adopts electric heating, and the three-stage thermocouples are arranged along the axial direction and are integrated and sealed. The thermocouple wraps the pipe, the outside of which is wrapped by foam for thermal insulation, and the outermost layer is wrapped with thermal insulation aluminum alloy to reduce heat loss. The power of each thermocouple is 200kw.

[0175] The heating section is set up vertica...

Abstract

The invention provides a supercritical water particulate matter visual measurement experimental device and method. The device comprises a preheating section for primarily heating fluid in a pipeline,a heating section for secondarily heating the fluid in the pipeline, a visual section for observing particulate matters, a cooling section for cooling the fluid in the pipeline, a pressure stabilizingsection for adjusting the pressure of a loop and a feeding section for adding water and particulate matters into the loop. The experimental device can study the flowing condition of fluid in the pipeline and the deposition movement condition of particulate impurities in the fluid in a visual measurement mode, is visual in observation, can accurately and effectively measure related data, and meetsexperimental requirements and engineering application.

Description

Technical field [0001] The invention belongs to the fields of energy, environmental protection, and mechanical equipment including nuclear energy, and is suitable for high-temperature and high-pressure fluids such as high-temperature water, supercritical water, ultra-supercritical water, and supercritical carbon dioxide, and is especially suitable for the flow characteristics of supercritical water in a reactor Research and study on the law of sedimentary movement of medium and fine particles. Background technique [0002] Supercritical water-cooled reactor (SCWR) is the only water-cooled reactor among the six types proposed by the fourth-generation nuclear energy system. It is an innovative design developed on the basis of existing water-cooled reactor technology and supercritical thermal power technology. Compared with the currently operating water-cooled reactor, it has the characteristics of simple system, small device size, high thermal efficiency, and better economy and saf...
