Study on water desalination system by solar energy distillation; Taiyo energy wo riyoshita joryugata kaisui tansuika system no kenkyu

Abstract

Discussions have been given on developing a seawater desalination system by solar energy distillation. The system is composed of evaporators installed on the seawater level, condensers placed on high and cool locations, and steam transport pipes to connect these two pieces of equipment. Steam is generated from seawater heated by solar heat in evaporators, and the steam is transported driven by low power consuming fans to higher locations through the steam transport pipes, where it is condensed by cool air in the condensers, and recovered as plain water. The concept is such that electric power required to operate the fans is supplied from photovoltaic panels, and all other energy is obtained from the sun. First, an experiment was performed upon noticing on methods of transporting and condensing the steam. The experiment used plain water rather than seawater. The heat source and evaporators were installed on the first floor, and the steam transporting fans on the second floor of an atrium. The thermal load was set to 1.5 times greater than average outdoor insolation amount. Increase in the distilled water recovery rate and distillation efficiency was verified by using the fans. The evaporation efficiency was found to tend to increase when  More>>
