本文提出了一种高产水比海水淡化装置的设计方案。该装置在进行工作时,盐水的最高温度为华氏250度。压缩比为1.58。高产水比的蒸汽压缩式流程用途广泛,既可用于双用途装置,也可用于单用途装置。采用了本设计方案就可较为容易地得到高产水比。从经济性方面来看,随着燃料价格的不断上涨,高产水比的流程正日益引人注目。本设计方案和工艺流程讨论了日产水量为237~*万加仑的装置。本方案采用了以柴油机为动力源,容量为65700英尺~3/分的离心压缩机,用它来操作与之相并联的四效立管泡沐式蒸发器(VTFE)。本方案采用了废热回收系统以及十七效立管泡沫式蒸发器,以便增加产水量。与普通的多级闪发式蒸发器相比,这种高产水比的装置在经济上具有竞争性。
In this paper, a design scheme of high yield water desalination plant is proposed. When operating the unit, the maximum brine temperature is 250 degrees Fahrenheit. The compression ratio is 1.58. Vapor compression processes with high water production ratios are versatile and can be used both for dual-use and single-use installations. With this design scheme, it is easier to get high water production ratio. From an economic point of view, the process of high-yield-water ratio is attracting more and more attention as fuel prices continue to rise. The design scheme and process flow discuss the device with a daily water volume of 237 to 10 000 gallons. The program uses a centrifugal compressor with a diesel engine as the power source and a capacity of 65,700 ft3 / min, which is used to operate a four-effect riser-foam evaporator (VTFE) in parallel with it. The program uses waste heat recovery system and seventeen efficiency riser foam evaporator, in order to increase water production. This high-water-ratio device is economically more competitive than a conventional multi-stage flash evaporator.
