Visualization experiment device for dynamic process of interaction between water and molten metal

Abstract

The invention discloses a visualization experiment device for a dynamic process of interaction between water and a molten metal. The device comprises a heating water tank, a water injection pipe and a reaction container, wherein the heating water tank is used for storing experimental water and maintaining a required temperature of the experimental water; the water injection pipe is arranged at the lower end of the heating water tank and integrally connected with the heating water tank; the reaction container is arranged below the water injection pipe, is used for containing the molten metal and heating the molten metal and comprises a reaction container pedestal and a heating plate, the heating plate is arranged in the reaction container pedestal, and a reaction process visual window is arranged on the reaction container pedestal. According to the visualization experiment device, the water injection speed, the water injection rate and the change from water column injection to water drop injection of the experimental water can be adjusted, the experimental process is externally and directly photographed through the reaction process visual window, and the reaction processes of an upper liquid level and a lower liquid level of the non-transparent molten metal can be simultaneously observed in the interaction process of water and the molten metal, thereby being favorable for the researches on types and occurrence mechanisms of the interactions between the water and the molten metal.

Description

technical field [0001] The invention relates to the technical field of the interaction experiment between water and molten metal and the simultaneous observation of the experimental process, in particular to a visualization experiment device for the dynamic process of interaction between water and molten metal. Background technique [0002] The phenomenon of explosive damage caused by the interaction of high-temperature low-volatile melts and low-temperature volatile coolants may occur in severe core melting accidents in nuclear reactors, and may also occur in steelmaking furnace accidents in metallurgical industries. Since the interaction between melt and coolant may cause huge economic loss and environmental damage, this complex physical phenomenon is an important research object in the field of international safety research. [0003] The interaction visualization experiment by injecting water into the molten metal is helpful to conduct a more in-depth study of the interac...
