Abstract
Official abstract text for this publication.
An embodiment of the present invention includes: a spiral type pressure vessel 15 in which a plurality of reverse osmosis membrane apparatuses 13 - 1 to 13 - 10 having spiral reverse osmosis membranes is connected through a permeated water pipe 14, and is housed in a connected state; a raw water supplying line that supplies raw water 11 into the pressure vessel 15; a concentrated water discharging line through which concentrated water 16 concentrated is discharged; a plug 17 that blocks the permeated water pipe 14 at the center of the reverse osmosis membrane apparatuses 13 - 1 to 13 - 10; a front-side permeated water line and a front-side permeated water line through which front-side permeated water 12 - 1 and rear-side permeated water 12 - 2 are discharged to the exterior, respectively, which are separated fore and aft, respectively, of the permeated water pipe 14 blocked by the plug 17; a pressure regulating valve 20 that is mounted in the raw water supplying line and regulates the supply pressure of the raw water 11; and a flow regulating valve 22 that is mounted in the front-side permeated water line and regulates the pressure of the front-side permeated water 12 - 1.

Opening claim text (preview).
1 . A spiral type seawater desalination apparatus comprising: a spiral type pressure vessel in which a plurality of reverse osmosis membrane elements having spiral reverse osmosis membranes to obtain permeated water by reducing a salt content from raw water is connected through a permeated water pipe; a raw water supplying line that supplies the raw water into the pressure vessel; a concentrated water discharging line through which concentrated water concentrated in the pressure vessel is discharged to exterior; a plug that blocks the permeated water pipe at a center of the reverse osmosis membrane elements in the pressure vessel; a front-side permeated water line and a rear-side permeated water line through which front-side permeated water and rear-side permeated water are discharged to exterior, respectively, which are separated fore and aft, respectively, at the permeated water pipe blocked by the plug; a pressure regulating valve that is mounted in the raw water supplying line supplying the raw water and regulates a supply pressure of the raw water; a flow regulating valve that is mounted in the concentrated water discharging line through which the concentrated water is discharged, and regulates a discharge flow rate of the concentrated water; a flow regulating valve that is mounted in the front-side permeated water line through which the front-side permeated water is discharged, and regulates a flow rate of the front-side permeated water, and an energy recovery apparatus that is mounted in the front-side permeated water line and recovers energy of the front-side permeated water with high pressure.
