Title: Flash distilling plant
IPC: B01D1/26
Filed: 1960-01-19
Abstract: Flash distillation is carried out in an apparatus comprising an elongated shell 1 divided by partitions 3 into two or more stages (there are three stages, indicated by references 4, 5, 6, in the embodiment shown), each stage having a longitudinal feed-duct 7 provided with a plurality of orifices, an excess feed channel 7a, and a bundle of condenser tubes 24 extending continuously in a straight line through all the stages via sealed-holes in the partitions.  The feed-ducts 7 are formed by wall 10, plate 11, and wall 8 provided with longitudinally-spaced orifices 9, wall 10 being arranged at an angle to wall 8, so that the cross-sectional area of the duct decreases in the downstream direction.  The preheated feed is supplied via inlet 12 to the duct 7 of the first stage, i.e. stage 4. The successive stages are maintained at increasing vacua by steam-jet pumps (not shown).  A mixture of flashed vapour and boiling liquid is ejected from the orifices 9 of ducts 7.  The liquid which is not evaporated in any stage collects in channel 7a, which increases in cross-sectional area in the downstream direction.  This unevaporated liquid flows through an opening in shell 1, down one side of a seal-pot 14, under wall 17, up the other side of the pot, and thence through another opening in the shell into the feed-duct 7 of the next stage. Liquid residue is withdrawn from the channel 7a of stage 6 via outlet 13.  The condenser tubes 24 pass through holes in partitions 3, sealing being achieved by providing, on the higher-pressure side of the partitions, rubber sheets with holes slightly smaller than those in the partitions.  The distil <PICT:0937374/III/1> <PICT:0937374/III/2> late, formed on tubes 24, collects on plate 20, flows into channel 20a, and passes into the channel 20a of the next stage via loop-seal 30.  The distillate is withdrawn from stage 6 via outlet 31.  The condenser tubes may be cooled by the liquid-to-be-distilled, which is introduced through inlet 27, and withdrawn through outlet 28.  Several shells of the above type may be connected up in series.
