Liquid medium minitype heat convection test loop

Abstract

The invention discloses a liquid medium minitype heat convection test loop which comprises a loop main body, an expansion box, and a gas system used for conducting vacuumizing and argon filling on the test loop, and is characterized in that the loop main body is a square circulation loop defined by a high temperature section (hot end, experimental section) and a low temperature section (cold end) in the vertical direction and a heating section and a cooling section in the horizontal direction, the expansion box is connected with the loop main body, and is positioned at the highest point of the circulation loop, and a valve is arranged on a connecting pipe of the expansion box and the loop main body. The test loop is concise, compact, high in realizability, low in cost, and easy to process and manufacture, and corresponding structural materials can be selected for construction according to experiment purposes so as to create corresponding experiment environment and working condition and to develop experiment research on material corrosion by liquid medium.

Description

technical field

[0001] The invention belongs to the technical field of material corrosion, and in particular relates to a small thermal convection test loop for studying the corrosion of materials by liquid media. Background technique

[0002] In various fields of industrial production and scientific and technological research and application, various liquid media are involved in long-distance transmission (or short-distance circulation transportation) in pipelines, such as long-distance transportation of crude oil in the energy field, acid used in chemical production, etc. Alkali salt, liquid metal medium transportation and casting in metallurgical industry, liquid metal (heat carrying or tritium multiplication) circulating flow in the field of nuclear industry and nuclear reactor engineering technology, etc. These liquid media will cause a series of problems during the transmission process, such as the erosion of the transmission pipeline by the flow of the medium, the cor...
