Natural Circulation Evaporator

Product Structure

It consists of a heating system, an evaporation separation chamber, a natural circulation pipeline, a vacuum system, and an intelligent control system. The heating system has a tube/plate heater, a foam removal device is installed in the evaporation and separation chamber, and the natural circulation pipeline uses density differences to drive the solution flow. The vacuum system uses a water ring/steam jet vacuum pump, and the intelligent control system is equipped with a PLC interface.

Operating Principle

Relies on temperature-driven natural convection without external circulation pumps. The heated material vaporizes to form a vapor-liquid mixture. Vapor is condensed and discharged, while the denser concentrated liquid flows back to the heater due to density differences. Continuous cycling achieves target concentration through repeated evaporation.
