Seawater Desalination device

The most economical and effective desalination technology with stable and reliable operation: MED is the most economical and effective desalination technology with the easiest operation at present. No matter low pressure steam (>0.3bar) or other waste heat, both can be reused effectively. The pure water produced can be used for public drinking or production process. Technical process: MET is a technology whose highest evaporative temperature is lower than 70°C. Its character is to connect all the horizontal tube falling film evaporators, and input certain steam to evaporator and condenser. The latter evaporative temperature is lower than the former, so as to get a desalination process that the mount of distilled water is many more times than that of steam consumption. Characteristics: Low operation temperature (<70°C), avoiding equipment Scaling and corroding to ensure the system stable and reliable. Simple operation systems to keep a continuous running. Adapting to a variety of water, easy pretreatment & low investment. Adapting to a wide range of seawater temperature(0°C-35°C) Low energy consumption, and low electric power consumption. High system heat efficiency High purity of fresh water TDS<5ppm Adapting to various heat resources, and according with national energy-saving and emission reduction requirements.

To increase daily output of fresh water, reduce energy consumption per unit, and ensure the system stable and reliable. 1.Process with energy recycling equipment Achieve internal energy reuse to improve the system energy efficiency. Increase comprehensive gain output ratio 10%-30%. 2.Unique slope layout of evaporatorheat exchange tube Guarantee condensed liquid in the heat exchanger to exclude rapidly. Enhance evaporator heat transfer area utilization to increase heat transfer coefficient. 3.Unique surface treatment technology of heat exchange tube Improve humidity and coverage using proportion of seawater on the heat exchange tube surface. Enhance heat exchange effect to increase output of fresh water and reduce energy consumption per unit. 4.Unique vacuum pumping system (patent technology) Adopt highly effective vacuum pumping set combined with the best vacuum pumping points inside to improve the heat transfer per- formance of the system greatly. Reduce the heat exchange effect of non-condensable gas to improve plant unit fresh water production and reduce energy consumption per unit. Reduce the danger of corrosion to improve units'reliability. 5.Optimized liquid spray system Perfect combination of spray and heat exchange tube ensures the steady liquid arrangement. Optimized arrangements of heat exchange tubes ensure the highest heat transfer efficiency.
