| 摘要 |
The invention relates to an arrangement for the multiple-stage evaporation of liquids and includes a plurality of evaporator units with associated separator arrangements and condensers connected downstream of the unit. The liquid to be vaporised is introduced into the evaporator stage most favourable with respect to the temperature of the liquid. The essential characteristic of the invention is that at least one heater and/or condenser downstream of the introduction unit of the evaporation stage is composed of a vertical tubular heat exchanger, two-stage with respect to the gaseous medium. |
