| 摘要 |
The invention is related to solar collectors intended to perform technological processes and specifically, to solar collectors used for concentration by evaporation of aqueous solutions. The proposed solar collector concentrates the aqueous solution by combination of heating the upper thin layer of this solution (this heating is accompanied with evaporation a significant part of this layer) and carrying away of the obtained vapors from the internal space of the solar collector by air stream introduced constantly into the internal space. In another version of this invention the obtained vapors are condensing on the surface of cooling water flowing through the solar collector.
