COMPACT DESALINATION OR DISTILLATION SYSTEM WITH INTEGRAL SPIRAL HEAT EXCHANGER

摘要

A vapor compression desalination or distillation system with a compact geometry that feature tripartite spiral fluidic pathways (60) that terminate a an evaporization zone within a plenum (63) internal to the spiral pathways inside of a housing. One side (66) of the zone receives sea water for distillation from one of the spiral pathways and ejects non-distilled water on the opposite side (68) in another spiral pathway. The heated central portion of the zone gives off vapor from the sea water that is collected in a shroud (73) that feeds radially inward ends of a compressor (71). Compressed vapor is ejected and collected from radially outward ends of the blades in a plenum (63), then fed as steam and condensate to an outflowing spiral pathway. The pathways are grouped in a tight spiral relation such that hot outflowing steam and condensate transfers heat to inflowing sea water in a heat exchange relation.
