Portable and stationary distillation unit for the simultaneous production of distilled water and salt, enhanched by solar collectors

摘要

The invention describes a new and simple method of construction of a stationary distillation unit and of a small portable distillation unit. The evaporation pans are made of simple materials and are covered with a transparent film. Additionally in the small portable unit its evaporation pan has a double bottom, which receives hot water. By connection of the evaporation pan with the solar collectors (12) its productive ability significantly increases. The portable and stationary desalination units of the invention use solar power exclusively and simultaneously produce two products: distilled water and salt. The exploitation of solar radiation occurs both in the part of the unit covered by the transparent film as well as in the use of hot water produced by the solar collector connected to it, thus speeding up the evaporation of sea water. The transparent film, besides helping increase and hold the heat inside the production space, also protects the production space from pollutants in the environment, and as a result the products do not need further processing before being sent to consumption. Besides the fact that each unit can be used as an autonomous production unit of distilled water and salt, the units can also function as sub-units of a production line of an unlimited number of sub-units, where their combined use functions as a large production unit of distilled water and salt.
