摘要： PURPOSE:To enalbe the title apparatus suitable for desalination of seawater, etc. to perform efficient evaporation by arranging a plurality of series each consisting of an effect and a flash evaporator; introducing brine preheated in each series into other series; and letting the brine flow down every series. CONSTITUTION:Seawater from piping 1 is passed through final condenser 2 to condense steam generated from final effect 8, and the seawater is drained. On the other hand, supplied seawater is passed through pipe 16, introduced into preheater 10 in flash evaporator 18 of the final evaporation unit, heated, and fed to degassing chamber 22. The seawater degassed in chamber 22 is supplied with pump 25 to feed water preheater 10 of the same series above effect 8, heated with steam generated in evaporator 18, and introduced into uppermost feed water preheater 10. After heat recovery the supplied seawater is introduced onto liquid distribution plate 11 of first effect 3 belonging to the first evaporation series and sprinkled upon horizontal heat transfer tubes 12 of effect 1.

摘要： PURPOSE:To prevent lowering in purity of fresh water and unstable running of brine by throttling a steam throttling member set to a steam pass leading to a condensation tray to reduce steam flow rate in the pass when bottom temp. lowers as the temp. of seawater lowers and it becomes difficult to maintain the designed desalination performance. CONSTITUTION:Brine flowing into evaporator 1 is flash evaporated in the flash box consisting of weir 7 and splash plate 6. Steam produced by the evaporation is splash separated in demister 4, condensed with a bundle of heat exchange tubes 5 through steam pass 3, and fed to fresh water tray 2 as fresh water. When the temp. of a heat medium (seawater) flowing through tubes 5 lowers as the temp. of seawater lowers, steam throttling member 8 is throttled to raise the resistance of pass 3. Accordingly, the amt. of steam flowing through pass 3 is reduced to maintain the desigen desalination performance.

CONSTITUTION:When a deposited film is formed on the porous body, valves 24 and 25 are opened, a pump 4 is driven to supply cleaning water on the downstream side of the porous body 1 of a vessel 2, and the air remaining in the vessel 2 is discharged from a pipeline 15 by the cleaning water. A valve 22 is then opened, the water in the vessel 2 is pressurized with the compressed air in an air tank 3, and then a valve 23 is opened. Consequently, pressure is uniformly exerted over the entire porous body 1, and the layer of the deposited suspended-matter is comletely peeled off.

摘要： PURPOSE:To adjust and control the composition of electrolyte so as to obtain tolerant potential difference generating no poisonous gas by monitoring the potential difference between an anode and an anolyte or the potential difference between a cathode and a catholyte. CONSTITUTION:In an electrodialyzer applying a DC power supply to an electrodialytic cell to separate desalted water and conc. water, the potential difference between an anode and an anolyte is monitored with respect to the generation of the chlorine gas from the anode of he electrodialytic cell to carry out operation so as to hold the potential difference to a prescribed value or less and, when the potential difference exceeds the prescribed value, the composition of electrolyte is adjusted or the electrolyte is replaced with a new one. The potential difference between a cathode and a catholyte is monitored with respect to the generation of the hydrogen gas from the cathode in the same way to carry out operation so as to hold the potential difference to a prescribed value or less. When the potential difference exceeds the prescribed value, the electrolyte is adjusted in its composition or replaced with a new one in the same way.

CONSTITUTION:The electrodialysis vessel 2-4 are provided in which numerous cation exchanging membranes K and anion exchanging membranes A are alternatively provided, and an anode chamber 3 is provided to one side of both end parts and a kathode chamber 4 to the other side. DC electricity is impressed to this electrodialysis vessel to generate desalted water 11 and concd. water 12. The reactions of oxidation and reduction are reversibly carried out between the anode chamber 3 and kathode chamber 4, and the solution, such as the mixed solution of FeCl2 and FeCl3, is circulated. As a result, as the reactions of anode and kathode are reversible reaction of oxidation and reduction, the need of supplying acid to kathode chamber is eliminated and gaseous chlorine and gaseous hydrogen are not generated.

摘要： PURPOSE:To effect stable concentration and dilution by disposing a rectangular cation exchange membrane, anion exchange membrane, and electrode in a longitudinal direction in a cylindrical electrodialysis drum. CONSTITUTION:Raw water, i.e., electrolytic solution, is fed into an electrodialysis drum 1. When D.C. current is applied between an anode 2 and a cathode 3, ions in the raw water move toward a cathode chamber 13 and, on the contrary, anions therein move toward an anode chamber 11. By the movement of these ions and by means of anion exchange membranes 4 and cation exchange membranes 5 arranged alternately, a large number of concentration chambers 8 and dilution chambers 9 are formed, wherein raw water passing through the chambers 9 becomes demineralized water, while raw water passing through the chambers 8 becomes concentrated water. And in the chambers 8, 9, ion exchange membranes with rectangular section are disposed in a longitudinal direction of the electrodialysis drum 1. In this manner, stable electrodialysis is effected.

CONSTITUTION:Most of seawater from seawater pump 62 is passed through final condenser 63 to condense steam from effect 30 of final evaporation unit 24 in final condensation chamber 53, and the seawater is drained through pipe 64. Part of seawater is passed through each feed water preheater 42 with pump 60 to condense steam generated in flash evaporation chamber 41 of each stage, and the seawater itself is heated and fed to the upper stage. Heat recovery is similarly carried out up to uppermost evaporation chamber 41, and the seawater is sprinkled upon horizontal heat transfer tubes 32 through liquid distribution plate 31 of first stage effect 30. Steam from heating steam pipe 33 is condensed along the inside of each tube 32, and the supplied seawater on the outside of each tube 32 is evaporated by heat exchange. The condensed steam is returned through condensed water piping 34 as condensed water.
