Figure 1As shown in the figure, the dotted line and the arrow leading from the end of the drainage component 40 represent the connection route of the drainage component 40, and the sewage generated during the experiment can be discharged to a designated location, meeting the experimental conditions required for various water injection methods, and obtaining the required experimental data under various working conditions. In addition, by setting a first temperature measuring component 21 at the first temperature measuring hole on the sealing cover 20, the temperature change of the steam generated by the steel slag in the tank body 10 after it meets water during the steel slag hot stewing experiment can be detected and known. At the same time, by setting a second temperature measuring component 11 at the second temperature measuring hole on the tank body 10, the temperature change of the steel slag in the steel slag hot stewing experiment can be detected and known. By setting a pressure measuring component 22 at the pressure measuring hole on the sealing cover 20, the pressure change of the steam in the steel slag hot stewing experiment can be detected and known. In addition, by setting an air extraction pipe 23 on the sealing cover 20 and connecting it to the tank body 10, the gas generated during the steel slag hot stewing in the tank body 10 can be obtained through the air extraction pipe 23, so as to facilitate sampling and analyzing the type and composition of the gas, thereby providing reliable, effective and comprehensive reference data for the steel slag hot stewing operation, which is beneficial to improving the efficiency and effect of the steel slag hot stewing operation.
