High efficiency, large scale desalination system

摘要

An apparatus and method for the distillation of ocean and brackish water that includes a means for using the ambient temperatures of seawater and air to continually transfer the heat energy, from the outer perimeters of the system, back into the, centrally located, evaporation chamber and insulation for preventing heat from escaping to the atmosphere. The insulation comprises a first and second wall surrounding the basic assemblies of a desalination system in which the space between the first and second wall is under low partial vacuum and is partially filled with an insulation material for structural support. The system provides a feed through means that prevent heat transfer through the structural connections between the first and second walls. The system provides an evaporation system for flash evaporation by atomizing the input contaminated water, preheated by the heat of condensation into very small liquid droplets, which are then sprayed into a stream of hot dry air. The liquid rapidly evaporates leaving behind hot dry solids that is recaptured and used to preheat the input contaminated water.
