SEAWATER DESALINATION SYSTEM AND METHOD

Title:

SEAWATER DESALINATION SYSTEM AND METHOD

Document Type and Number:

Japanese Patent JP2014188399

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a seawater desalination system and a method each capable of enhancing the heat exchanging efficiency by fixing the heat exchange temperature difference of compressed steam and seawater.SOLUTION: A seawater desalination system 1 includes an initial-end evaporation unit 2 positioned at the initial end and one or multiple posterior-side evaporation units 3 connected serially toward the downstream side. The initial-end and the posterior-side evaporation units each include: an evaporator 5; an evaporated matter flow channel 8 through which steam or distilled water is distributed; a compressor 11 for compressing the steam; a heat exchanger 12 configured within the evaporator; and a concentrated matter flow channel 10 through which a concentrated matter is distributed. The evaporator possessed by the initial-end evaporation unit is connected to a seawater supply flow channel 13 through which seawater is distributed, whereas the evaporator possessed by each posterior-side evaporation unit is connected either to the initial-end evaporation unit positioned on the upstream side or to the concentrated matter flow channel extending from the evaporator possessed by the posterior-side evaporation unit. The seawater desalination system 1 further includes a preheater 15 for executing heat exchanges among the seawater distributed through the seawater supply flow channel, distilled water distributed through the evaporated matter flow channel, and concentrated water distributed through the concentrated matter flow channel extending from the final-end evaporation unit.
