ABSTRACT:
A double-effect evaporator comprises a first and a second effects and an external steam ejector, each of the effects having feed-liquid spray means, a bundle of heat-transfer tubes below the spray means and extending between headers, and a concentrated liquid collector. The first effect heat-transfer tubes extend perpendicularly to the second effect tubes. A suction port of the ejector opens into the second effect evaporation chamber. A diffuser of the ejector extends in parallel to the second effect heat-transfer tubes. A discharge port of the ejector opens into the inlet header of the first effect. The first effect evaporation chamber is connected with a duct straight to the inlet header of the second effect.
