Title:
DESALINATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/129132
Kind Code:
A1
Abstract:
Provided is a desalination system that can efficiently accumulate surplus electrical power which was created in the generation of electrical power using natural energy, and accumulate such surplus electrical power in a form other than electrical power. A seawater desalination device (1) is connected to a natural energy power generator (11). Therefore, when surplus electrical power (13) is created in the generation of electrical power using the natural energy power generator (11), the seawater desalination device (1) is driven by the surplus electrical power (13). This being the case, raw water in a raw water tank (2) is supplied to a first saltwater reactor (4) by a high-pressure pump (3) and permeabilized by the first saltwater reactor (4) and a second saltwater reactor (5) to produce intermediate water. This intermediate water is then supplied to a brackish water reactor (7) by a low-pressure pump (6). The intermediate water is permeabilized by the brackish water reactor (7) to produce freshwater and the freshwater is retained in a freshwater tank (8). Consequently, surplus electrical power is retained in the form of freshwater and therefore the usage efficiency of surplus electrical power can be increased. If the first saltwater reactor (4) and the like are of the flux-smoothing type, efficiency can be further improved.
