Abstract

This paper is aimed at designing, constructing and performance evaluation of a solar still. The solar still is design and constructed with locally source materials for rural dwellers. The still absorber plate is constructed with 2 mm galvanised plate painted black with an area of 2 m 2 to absorb solar radiation effectively. The side wall and the base is constructed with concrete. Sawdust and felt is used between the retaining wall and base to resist heat transfer from the system to the surrounding vice-versa. The top cover of the still is constructed with transparent glass pane of 4 mm housed in an aluminium frame. The catch basin that collects the condensate is constructed with PVC pipe channel of 50 mm. The performance of the still was evaluated with; Overall yield (sum of daily yield and over-night yield) at a different water depth of (20, 40, 60 mm), (5127 ml/m2/hr, 4558 ml/m 2 /hr, and 3852 ml/m 2 /hr). The efficiency of the system at different water depth (20, 40, 60 mm) 51.27 %, 45.58 %, and 38.52 %. The water analysis before and after distillation was certified safe and portable for human consumption.

农村太阳能蒸馏器的设计、施工及性能评价

本文对太阳能蒸馏器的设计、构造及性能评价进行了研究。太阳能蒸馏器是为农村居民设计和建造的，使用当地的材料。静止吸收板由2毫米镀锌板构成，涂成黑色，面积为2平方米，有效吸收太阳辐射。侧壁和基础用混凝土建造。在挡土墙和底座之间使用锯末和毛毡，以防止热量从系统传递到周围环境，反之亦然。蒸馏器的顶盖由4毫米的透明玻璃板构成，玻璃板装在铝制框架内。收集冷凝水的集水盆采用50mm的PVC管通道。用;在不同水深(20、40、60 mm)、(5127 ml/m2/hr、4558 ml/m2/hr和3852 ml/m2/hr)下的总产量(日产量和隔夜产量总和)。系统在不同水深(20、40、60 mm)下的效率分别为51.27%、45.58%和38.52%。蒸馏前后的水分析被证明是安全的，可携带供人类食用。
