[0002] In a broad sense, a reaction vessel is a container where physical or chemical reactions occur. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. Reaction vessels are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries, serving as pressure vessels for processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation. Existing reaction vessels mostly rely on steam heating, and the steam used for heating is often directly discharged without effective utilization, thus reducing the overall energy efficiency. Therefore, we propose a reaction vessel preheating and recycling device. Summary of the Invention

The heat exchange tubes have a U-shaped cross-section, and their upper ends extend through the fixed plate to both sides of the partition. An air inlet pipe is provided on one side of the upper end of the end cap, and the air inlet pipe is connected to the air outlet of the reactor base through a guide pipe. An air outlet pipe is provided on the side of the end cap away from the air inlet pipe.
