摘要
为了利用分布式小型海水脱盐装置生产淡水,文章提出了一种新型管式降膜太阳能海水蒸馏装置,并分析了该装置的产水性能,以及进料海水盐度、进水流量等对该装置的产水速率、冷凝温度、排浓海水温度等的影响。研究结果表明:产水速率随着进料海水盐度的增加而减小,在运行温度为80℃的情况下,当进料海水盐度为3.5%时,产水速率为151.02 g/10 min,比进料海水盐度为10.5%时增加了20.33%;产水速率随着进水流量的减少而增加,在运行温度为80℃的情况下,当进水流量为0.44 kg/h时,产水速率为0.907 kg/h,比进水流量为0.68 kg/h时增加了21.42%;通过管式降膜太阳能海水蒸馏装置的模块化组合,可以满足用户不同的淡水需求量。
A novel small-size solar seawater distillation device with tubular falling film evaporation has been introduced to meet the demand of fresh water for distributed desalination. Meanwhile the fresh water production performance of the device was analyzed. An experimental investigation was carried out to investigate the effect of feed seawater salinity and feed water mass flow rates on fresh water production, condensation temperature and concentrated brine temperature. Results indicate that, the hourly yield of the experimental device decreases with an increase of the feed seawater salinity. Distillated yield of the device can reach 151.02 g/10 min at the operating temperature of 80℃ and the salinity of 3.5%, which is more than 20.33% that at the salinity of 10.5%. In addition,the hourly yield of the experimental device increases with a decrease of the feed water mass flow rate. Fresh water productivity of the device can reach 0.907 kg/h at the operating temperature of 80℃ and the feed water mass flow rate of 0.44 kg/h, which is more than 21.42% that at the feed water mass flow rate of 0.68 kg/h. The modular assemble of the device can meet the requirement of different fresh water consumers.
