Monitoring device and monitoring method for high-temperature multiphase interface reaction

The invention discloses a monitoring device and a monitoring method for a high-temperature multiphase interface reaction, the monitoring device for the high-temperature multiphase interface reaction can be used for simulating a gas-liquid-solid multiphase high-temperature interface reaction, such as simulating a titanium extraction tailing-water vapor-oxygen multiphase interface reaction, and in the reaction process, the gas-liquid-solid multiphase high-temperature interface reaction can be simulated; the fluidization state of the titanium tailings extracted on the porous quartz plate can be observed by pulling and opening the monitoring door, the mass change of the whole reaction system is monitored through the mass sensor, and the pressure change of the whole reaction system is monitored through the pressure sensor, so that the purpose of monitoring and researching the high-temperature multiphase interface reaction process is achieved. The method is convenient for exploring and researching the essence and m
