Low-temperature Multi-effect Distillation Plant

Low temperature multi-effect distillation for seawater desalination unit, which is one of the most widely used and advanced seawater desalinization unit at present, is the development tendency of thermal seawater desalinization. The principle is that in the heat exchange tube, the heat released by steam condensation evaporate the seawater out of the tube to form a secondary steam, the secondary steam flows into the next effect evaporator as the heating steam of the next effect evaporator, this cycle continues until the final effect.

Application

Low temperature multi-effect distillation for seawater desalination unit can be used in steel mill, power plant, and chemical plant. By using the waste heat of the plant, the seawater is desalted and the pure freshwater produced can be used for production process or public drinking. Nowadays it is the most efficient, economical and convenient system for seawater desalination.

Features

01.Due to the low requirements to seawater pre-treatment, the equipment can adapt to various qualities of sea water. The process of sea water pre-treatment is simple, the temperature range (0 ℃ ~ 35 ℃) of seawater is wide and the investment cost is low.

02.It meets the national requirements of energy conservation and emission reduction with the characteristics of low cycle power consumption, high thermal efficiency of the system, the use of waste heat of the plant and low power consumption(less than 1.25kwh /t).

03.Low operating temperature (<70℃) can avoid scaling and corrosion of the equipment, and easy, stable and reliable operation system can ensure the continuously operation of the system.
