Thermohydraulic experiment system related to the interaction between melt and coolant

Abstract

The invention discloses a melt-coolant interaction relevant thermotechnical hydraulic experiment system. The experiment system comprises an experiment stainless steel platform, a high-temperature furnace system, a protecting gas system, a cooling system, a heating control system, an experiment water tank system, a high-speed photography system and a lifting platform, wherein the experiment stainless steel platform is divided into an upper layer and a lower layer, the upper layer is formed by the steps of paving a stainless steel plate, and mounting stainless steel fences around the stainless steel plate; and the lower layer is formed by the steps of welding and sealing the periphery of the stainless steel plate to form a closed space, and forming two doors for going in or out, wherein people can go up and down through ladders. According to the experiment system, the interaction experiment between a high-temperature melt (with the highest temperature of 2700) and cooling water can be realized, so that relevant researches of a super-high temperature reaction phenomenon are promoted; the continuous online feeding can be realized in the experiment process of the interaction between molten metal and a coolant, so that the experiment efficiency is improved; and the reaction process can be simultaneously visually observed front different angles, so that the mechanism research on the interaction between the molten metal and the coolant is promoted.

Description

technical field [0001] The invention relates to an experiment system, in particular to a thermohydraulic experiment system related to the interaction between melt and coolant. Background technique [0002] The phenomenon of explosive damage caused by the interaction between high-temperature low-volatile melt and low-temperature volatile coolant may occur in severe core melting accidents of nuclear reactors, and may also occur in steelmaking furnace accidents in the metallurgical industry. The impact of smog may cause huge economic loss and environmental damage, so this complex physical phenomenon is an important research object in the field of international security research. [0003] The visualization experiment of the interaction between the molten metal and the coolant helps to conduct a more in-depth study of the interaction mechanism and reaction process. However, due to the simple experimental system, low experimental temperature and low experimental efficiency in the ...
