AI Technical Summary
Existing industrial naphthalene extraction processes consume a lot of energy during heating and cooling, have low condensation efficiency, and are prone to clogging of condensation pipes, resulting in high purification costs and severe reflux of the mixture.
The purification tank adopts a double-layer tank structure, combined with a spiral heating coil and a stirring system to achieve segmented heating and uniform stirring; the design of the bucket head and condensing pipe prevents the mixture from flowing back, and the condensing system improves the condensing efficiency.
It reduces energy consumption, improves heating uniformity and condensation efficiency, prevents mixture backflow, reduces production costs, and enhances the durability and condensation effect of the purification tank.
