Melts and coolant interacting relative thermal-hydraulic research experiment water tank

Abstract

The invention discloses a melts and coolant interacting relative thermal-hydraulic research experiment water tank, a main body of the water tank is used for inlet and outlet and storage of a coolant, a thermocouple and a pressure sensor are provided outside the main body of the water tank, a visual window is arranged on the wall surface of the main body of the water tank, the visual window and the main body of the water tank are sealed; a heating device is arranged in the main body of the water tank and is used for heating of the coolant in the water tank and controlling the temperature; a lifting mechanism is connected to a metal collection plate for controlling the lifting and decrease of the metal collection plate; the metal collection plate is arranged in the main body of the water tank for collecting the metal after the teats and measuring the size of the metal particles. According to the invention, water-infusion amount is changed, visualization is realized, temperature and pressure enable real-time acquisition, the metal particles after tests are collected, and the particles size is measured. In the experiment process, a reaction process can be observed from four directions simultaneously, and the experiment water tank is helpful for researching the interacting types of the molten metal and the coolant and a generation mechanism.

Description

technical field [0001] The present invention relates to the technical field of thermal-hydraulic research experiment research, in particular, to a thermal-hydraulic research on the interaction between molten metal and coolant for simultaneous observation and measurement of the experimental process. Experimental tank. 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] Through the visualization experiment of the interaction between molten metal and coolant, it is helpful to conduct a more in-depth st...
