| 摘要 |
The invention relates to a device for the distillation of a liquid, with at least one mirror surface for focusing solar radiation onto an absorber tube which can be filled at least partly with the liquid, wherein the absorber tube, is provided, for taking up energy from the solar radiation and for evaporating the liquid, and to at least one first condensation tube for condensing the evaporated liquid, the first condensation tube being disposed at a distance from the absorber tube, to which it is coupled by at least one distillation bridge. In order to make a simple and cost effective distillation device possible, with which a particularly efficient utilization of the solar energy for a high distillation performance is achieved, it is provided that a transparent sleeve is coupled thermally with the condensation tube and surrounds the absorber tube, a space remaining between the sleeve, and the absorber tube. |
