Embodiment 2
[0066] Such as Figure 4 As shown, in Embodiment 2 of the present invention, thermogravimetric analysis is carried out on a large sample size particle sample, including a high temperature reactor 2, an electric heating furnace 1, a hydraulic lifting platform 3, a sealed box 4 and a gas source;
[0067] Such as figure 2 As shown, the high temperature reactor 2 is composed of an inner pipe 2-1 and an outer pipe 2-2, and the inner pipe 2-1 is composed of an integrated pipe body 2-11 and an expansion head 2-12 from bottom to top, The expansion head 2-12 is a rotating body, and its maximum diameter is larger than that of the pipe body 2-11. The bottom of the pipe body 2-11 has uniformly distributed holes, and the maximum diameter of the expansion head 2-12 has two symmetrical outlets. Gas port 2-12A, the pipe body 2-11 is located in the outer pipe 2-2, forming a coaxial sandwich casing structure, and the upper part of the outer pipe 2-2 has a reaction atmosphere inlet 2-2A;
