A newly designed multiple-effect solar still with a triangle cross-section consisting of a horizontal basin liner, a tilted double glass cover and the vertical parallel partitions in contact with saline-soaked wicks was presented. Solar radiation is absorbed in the basin and in the first partition, and the partition section recycles the energy from the basin as well as the absorbed solar energy to increase drastically the distillate productivity.The proposed still was theoretically analyzed at various values for design, operational and weather parameters to determine the optimum values for the parameters. A solar still was constructed based on the optimum values and then outdoor experiments with the still were performed over two years. The distillate productivity of the still was less than the theoretical predictions by 20-30% for the first test period. After sandwiching 20 small lumps between each partition and the next one, the productivity increased and was as much as the theoretical predictions. It was found that the proposed still is more productive by 50% or more than the conventional multiple-effect solar still consisting of tilted parallel partitions, and the maintenance of the proposed still requires less effort and cost.

介绍了一种新型的多效太阳能蒸馏器，该蒸馏器由水平的内胆、倾斜的双层玻璃盖和与盐水芯接触的垂直平行隔板组成，截面为三角形。太阳辐射在池和第一隔板中被吸收，隔板部分将来自池的能量以及吸收的太阳能重新分配，以大幅提高馏出物生产率。根据最佳值建造了一个太阳能蒸馏器，然后用该蒸馏器进行了两年多的室外实验。蒸馏器的馏出物生产率在第一个试验期比理论预测低20-30%。在每个分区和下一个分区之间放置20个小块之后，生产率增加，并且与理论预测一样多。发现所提出的蒸馏器比由倾斜的平行隔板组成的传统多效太阳能蒸馏器的生产率高50%或更多，并且所提出的蒸馏器的维护需要较少的努力和成本。
