A plurality of annular heating tubes 112 are arranged inside the cavity 111. The plurality of annular heating tubes 112 are arranged in a straight line along the inside of the cavity 111.

[0028] The improvement lies in that: multiple annular heating tubes 112 are evenly distributed inside the cavity 111, so that heat can be evenly and quickly transferred to the inside of the reactor body 10, thereby improving heat conduction efficiency and shortening reaction time; at the same time, the annular heating tubes 112 adopt an intelligent temperature control system, which can accurately control the heating temperature, ensure the stability and safety of the reaction process, and avoid economic losses.

[0029] Secondly, the specific structure of the stirring assembly 21 is disclosed. The stirring assembly 21 at least includes a mounting box 211. The mounting box 211 is arranged on the upper surface of the cover plate 20. A motor 212 is arranged inside the mounting box 211.
