MULTI-STAGE EVAPORATION DEVICE WITH COMPRESSOR SUPPORT FOR DELIVERING HEATING HEAT TO SEAWATER DESALINATION PLANTS

摘要

The seawater desalination plant is powered by heat supplied from solar collectors and a compressor with a low pressure (181) and high pressure (182) section, and an evaporation assembly. The heat feed from the collector circuit (1) is through a unit for relief evaporation (7) through the removal of vapor (16). The lost volume through vapor extraction is replaced by distilled water (15) from the desalination plant. The relief evaporation unit is divided into a number of sub-units (71-73) in series with a declining pressure level, in series with the intermediate compressor stages (182-1-182-2) in a sequence of increasing pressures.
