AI Technical Summary
Hydrochloric acid residue easily adheres to the inner wall of the condenser tube, forming crystal scale that is difficult to clean thoroughly using conventional cleaning methods, leading to decreased heat exchange efficiency and maintenance difficulties.
A condensation and collection device for a high-purity hydrochloric acid subboiling distillation system was designed. The device is connected by a combination of guide rod and threaded rod, which facilitates the separation of the upper and lower condenser tubes and makes internal cleaning easier. The device also prevents hydrochloric acid leakage and thermal expansion and contraction through a sealing sleeve and a corrugated compensation tube.
It enables rapid cleaning of condenser tubes, reduces cleaning difficulty, improves the stability and sealing of the device, prevents hydrochloric acid leakage, and extends the equipment maintenance cycle.
