汽液分离元件是热法海水淡化装置中至关重要的组成部分,它的主要作用是除去蒸汽中的盐雾液滴,保证淡化产品水水质。通过优化研究汽液分离元件的结构和操作工况可以提高其分离性能,达到提升装置效率、提高产水水质和节约生产成本的目的。本论文综述了应用于海水淡化装置的折流板式和丝网式汽液分离元件的性能特点,总结了国内外研究进展及部分工程案例,并对其发展前景进行了展望。
Abstract：Gas-liquid separation element,the most important part in the hot desalination process,plays an important role in eliminating saline fogy droplets in the steam and ensures the quality of product water.Optimizing the structure of separation element and operating condition can enlarge the separating capacity,improve efficiency,increase the quality of product water and decrease the cost of production.In this paper,the characteristics of the wave-plate mist eliminator and wire mesh eliminator applied in desalination process of sea water were reviewed.The progress and some application cases in desalination plant were introduced and the prospect was proposed.
