The middle liquid delivery assembly 4 is located between the liquid outlet assembly 3 and the top liquid delivery assembly 5. Two liquid heating tanks 6 are respectively located on both sides of the reaction tower body 1. The bottom of the liquid heating tank 6 is communicated with the liquid outlet assembly 3.

A liquid heating cover 2 is fixedly connected to the outer wall of the reaction tower body 1. The inside of the provided liquid heating cover 2 can be used for the circulation of heating liquid. The reaction tower body 1 can be heated by the high-temperature liquid inside the liquid heating cover 2. Further, a liquid outlet assembly 3, a middle liquid delivery assembly 4, and a top liquid delivery assembly 5 are fixedly arranged outside the liquid heating cover 2. The liquid outlet assembly 3 is communicated with the middle liquid delivery assembly 4 and the top liquid delivery assembly 5 through two liquid heating tanks 6, two first liquid pumping assemblies 7, and two second liquid pumping assemblies 8 respectively. Thus, when the first liquid pumping assembly 7 and the second liquid pumping assembly 8 are started, the relatively low-temperature liquid can be pumped into the liquid heating tank 6 from multiple circumferential parts at the bottom of the liquid heating cover 2 through the liquid outlet assembly 3. The liquid heating tank 6 can heat-treat the liquid flowing inside.
