| 摘要 |
<p>A device (1) for separation and/or purification of the solvent by means of evaporation of the solvent and subsequent condensation of at least a part of said vaporised solvent, and a reservoir for the contamined solution (3), wherein the device (1) comprises a vapour chamber (4), with an evaporation surface (2) having a first temperature for evaporating the solvent (3) and a condensation surface (7), having a second temperature for condensation of the vaporised solvent and means for removing the condensed solvent (9) from the vapour chamber (4). The invention is characterised in that the vapour chamber (4) is at least partly submerged in the reservoir for the contamined solution (3), in that the evaporation surface (2) is closed off by the contamined solution, and in that means are provided for heating the contaminated solution in the reservoir.</p> |
