SOLAR DESALTING UNIT Russian patent published in 2001 - IPC

FIELD: thermal engineering; domestic low- capacity desalting units. SUBSTANCE: unit has solar collector and multiple- section vacuum distiller. Test and evaporation-condensation heat-transfer apparatuses of distiller are made in the form of spiral tubes with turns arranged horizontally. Brine is evacuated from distiller by means of water-air ejector. Specific capacity of unit depends on number of sections engaged in process and amounts to 1-3 liters of distillate per hour from one square meter of solar collector.
