Description

The invention relates to shipbuilding, in particular to ship desalination facilities.

The purpose of the invention is to increase the efficiency by reducing scale formation when using a hydrophobic coolant with a specific weight less than the specific gravity of seawater.

The drawing shows the proposed installation.

The installation includes a housing 1, an evaporator made in the form of a chamber 2 immersed in a glass 3 and hermetically attached to the upper end of the glass, a condenser 4, a steam washer 5. The evaporator has a hydrophobic heat transfer fluid cavity 6 with a specific weight less than the specific weight of sea water, a residual cavity brine 7. Under the steam-flushing device above the cavity of the heating coolant there is a distribution grid 8 of feed water, into which water is fed by the feed pump 9, as well as into the condenser through a pipe line 10. The feedwater supply to the distribution grid is dosed out by the supply regulator 11. connected to the temperature sensor 12. The residual brine and sludge released in the form of sludge are discharged through the nozzle 13 and the brine level regulator 14 connected to the level sensor 15 brine through pipeline 16 to the ejector 17 for removal overboard. The water in the ejector pump flows from the condenser cooling line through pipe 18. Condensate is discharged from the condenser by condensate pump 19 through the pipe 20. Partially enters the steam and flush device through

pipe 21. The hydrophobic heating coolant enters the evaporator through pipe 22 and is discharged to the heat source through pipe 23. The heating water level is maintained below the distribution grid and above the inlet pipe 22. With the feed pump 9 one part of the water is supplied to condenser 4, then pipe 18 and ejector 17. Another part of the feed water is supplied to the distribution grid 8 by means of the supply controller 11, operated from the signal from the sensor 12, dispersed over the heated hydrophobic heat carrier. I eat without lysing not chemically react with sea water scum, and dissolved gases in the water. (Hot oil may be used). Heating and evaporation of the sinking dispersed particles of feed water is carried out by contact. The dispersed particles sink down together with the heating coolant, are heated to the boiling point, sink, evaporating water. On the surface of the hydrophobic coolant, only steam emerges, and the residual brine and the hydrophobic coolant released into the medium in the form of sludge scale are separated from the heating coolant at the lower edge of the evaporator chamber 2 and collected in the cavity of the residual brine 7, passing through level 13 and level 14 regulator the residual brine operating from the brine level sensor 15 is discharged through line 16 to ejector 17 to collect overboard. The hydrophobic coolant rises through the gap between the walls of chamber 2 and cup 3, is discharged through pipe 23. Steam is cleaned in the steam washer 5, condensed in condenser 4. Condensate is discharged by pump 19 through pipe 20, while partially entering into the steam washer 5, steam cleaning.

The amount of feed water supplied to the evaporator is controlled by a temperature sensor 12 measuring the residual temperature of the heating coolant at the end of the heat transfer to produce steam at the lower end of the evaporator chamber 2.

The proposed installation allows desalination of water without deposition of scale on the walls of the evaporator and removes scale formed in the form of sludge with residual brine overboard in the environment of the hydrophobic coolant.
