Abstract
Relating to a seawater desalination system, the invention provides a little power consuming seawater desalination system. The invention aims to provide a solution to the problem of high power consuming cost existing in present seawater desalination systems employing industrial exhaust heat. One of the two secondary steam outlets of the exhaust-heat boiler is communicated with the steam inlet of an organic Rankine power generation set, and the remaining one of the two steam outlets of the exhaust-heat boiler is communicated with a seawater desalination device. A vacuum pump is communicated with the seawater desalination device that is communicated with a condensing unit, and the vacuum pump operates with power supplied by the organic Rankine power generation set. The seawater desalination system is used for seawater desalination.
