AI Technical Summary
In existing chemical mixing reactors, heating coils are easily adhered to or left by reactants, making cleaning difficult and affecting subsequent reaction processes.
A shell is installed over the heating coil, and a heat-conducting medium is filled between the shell and the inner wall of the reactor to prevent the raw materials from directly contacting the heating coil. At the same time, steam is introduced through the inlet and outlet pipes for heating. Combined with the design of the stirring device and the feeding tank, uniform mixing and heating are achieved.
This effectively avoids contact between the raw materials and the heating coil, simplifies the cleaning process, and ensures heating effect and mixing uniformity, thereby improving reaction efficiency.
