Forced circulation evaporator

Scope of application of forced circulation evaporator

Compulsory circulating evaporator is suitable for evaporation and concentration in chemical, food, pharmaceutical, environmental protection engineering, waste liquid evaporation recovery industries with scaling, crystallinity, heat sensitivity (low temperature), high concentration, high viscosity and insoluble solids.

Working Principle of Forced Circulation Evaporator

A class of evaporation equipment. The circulation of the solution in the equipment mainly depends on the forced flow generated by the external power. Circulation speed can generally reach 1.5-3.5 m/s. Heat transfer efficiency and productivity are higher. The feed liquid is injected from bottom to top by the circulating pump and flows upward along the tube of the heating chamber. The mixture of steam and liquid foam is separated after entering the evaporation chamber. The steam is discharged from the upper part, and the fluid is blocked to fall down. It is inhaled by the circulation pump through the conical bottom, and then enters the heating pipe to continue the circulation.

Advantages and disadvantages of forced circulation evaporator

Advantages: high heat transfer coefficient, anti-salting out, anti-scaling, strong adaptability, easy cleaning.

Disadvantages: high kinetic energy consumption, long residence time of solution, slightly higher cost of construction and maintenance.https://www.heczb.com/
