MEMBRANE DISTILLATION DEVICE

摘要

The invention relates to a membrane distillation device comprising one or more multi-stage membrane distillation modules with in each case an evaporator, at least two, in particular at least ten condensation and evaporation stages and a condenser, wherein each condensation and evaporation stage comprises a vapour chamber, a liquid channel for a liquid to be concentrated, a condensation partition separating the vapour chamber from the liquid channel and a membrane wall that delimits the liquid channel on the side opposite the condensation partition. The membrane distillation device is characterized in that the respective subsequent condensation and evaporation stage with its vapour chamber directly adjoins the membrane wall of the previous condensation and evaporation stage, said membrane wall thus separating the liquid channel of the previous condensation and evaporation stage from the vapour chamber of the subsequent condensation and evaporation stage.
