Rotary high-temperature fused salt corrosion characteristic simulation system

Abstract

The invention discloses a rotary high-temperature fused salt corrosion characteristic simulation system, which belongs to the field of heat storage medium detection devices for concentrated solar thermal power generation. The rotary high-temperature fused salt corrosion characteristic simulation system comprises a fused salt tank, a stirring apparatus, a motor and a motor lifting apparatus for controlling the lifting of the motor, wherein an electric heating apparatus is also arranged in the fused salt tank; one end of the stirring apparatus is fixed on the bottom of the motor, the other end stretches into the fused salt tank, the stirring apparatus can be driven by the motor to lift and rotate, and one end, which stretches into the fused salt tank, of the stirring apparatus is provided with a sample wafer to be tested. By utilizing the rotary high-temperature fused salt corrosion characteristic simulation system, the corrosion condition of the fused salt medium, the flow rate, the temperature and the like on the metal sample wafers made of different materials can be comprehensively and effectively reflected, the system can continuously run (2000h or longer) for a long time at a high temperature state, so that the field can be more actually simulated, and the corrosion result analysis of the sample wafer to be tested is more convincing.

Description

technical field [0001] The invention belongs to the field of thermal storage medium detection equipment for concentrating solar thermal power generation, and in particular relates to a rotating high-temperature molten salt corrosion characteristic simulation system. Background technique [0002] Energy occupies a very important position in the process of social development. With the continuous development of my country's economy, energy consumption is also increasing. Concentrating solar thermal power generation (CSP) is easy to integrate and thermal energy storage system (TES) is feasible. The reliability and high efficiency make CSP commercially more attractive than other renewable energy sources. Among CSP thermal storage media, molten salt mixtures are often used as heat transfer fluid (HTF) and thermal energy storage (TES) media due to their advantages such as high thermal conductivity, good thermal and chemical stability, and fast mass transfer rate.

Problems solved by technology

However, in such experimental results, the pattern corrosion is often very uneven, and the parts in contact with the crucible wall are more severely corroded, and it is precisely because of the contact that the crucible wall interferes with the metal pattern, so the corrosion results cannot really reflect the effect
