用于大型低温多效海水淡化真空系统的自主设计与工程实践

INDEPENDENT DESIGN AND ENGINEERING PRACTICE OF THE VACUUM SYSTEM APPLIED TO LARGE-SCALE LOW-TEMPERATURE MULTIPLE-EFFECT SEAWATER DESALINATION

为解决海水淡化装置真空机组选型问题,对日产淡水万吨级的大型低温多效海水淡化装置真空系统的设计参数探讨,介绍了该领域在消化吸收国外技术的基础上自主设计的方式方法,为今后设计适用于大型低温多效蒸发海水淡化工程的真空系统,提供了可借鉴的设计案例与工程实践。

In this paper, combined with the engineering practice, the design parameters of the vacuum system are discussed, which can be applied to large-scale low-temperature multiple-effect seawater desalination and produce ten-thousand tons fresh water daily. Furthermore, the independent design methods and ways which are based in taking in abroad technology in this field are introduced. The design case and engineering practice for reference are provided for designing vacuum system suit- able for large-scale low-temperature multiple-effect seawater desalination system in future.
