Inflatable non-imaging solar concentrator water desalination system

Abstract

An inflatable non-imaging solar concentrator water desalination system comprises an inflatable non-imaging stationary solar concentrator and shallow black basin type evaporator. The evaporator is made into a semi-close structure house like a stadium to surround the concentrator. An absorber made of black coating or porous absorption materials is placed on the basin of the concentrator. The evaporator consists of an inner holder, a outer holder, a freshwater collector, and a condenser to form a space for water to evaporate, and to be condensed and collected. The inflatable non-imaging solar concentrator is assembled with the evaporator in such a way that the output aperture of the solar concentrator is directly over the surface of the absorber

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate an embodiment of the invention and together with the description, serve to explain the principles of the invention.

[0011] FIG. 1 is the overview of the assembly of the inflatable non-imaging solar concentrator water desalination system. It is a combination of a inflatable non-imaging solar concentrator and a shallow black basin based evaporator as a envelope to the solar concentrator.

[0012] FIG. 2 is the cross section of the assembly of the inflatable non-imaging solar concentrator water desalination system. Where, the close structure of the solar concentrator, the structure of the evaporator consist of shallow black basin, the house formed by inner and outer holders, and the combined condenser and collector, are shown.

DETAILED DESCRIPTION

[0013] Reference will now be made in detail to the present exemplary embodiment, example of which is illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0014] Referring to FIG. 1, the inflatable non-imaging solar concentrator water desalination system comprises two major components inflatable non-imaging solar concentrator 100, which is a close structure stationary solar concentrator and is able to concentrate both beam light and diffuse light, and evaporator 200 as an envelop surrounding the concentrator 100. The bottom of the concentrator 100 is directly sitting on the bottom of the evaporator 200 to concentrate the incident light to the absorber located on the bottom of the evaporator 200. The brine water feeding in the basin of the evaporator 200 is evaporated by the absorber.

[0015] Referring FIG. 2, the evaporator 200 consists of the black basin 210, the outer holder 220, the freshwater collector 230, the condenser 240, the inner holder 250, and the absorber 260. The inner holder and outer holder form a house for evaporation. When in operation, the brine water is feed in the basin 210; the incident sunlight is concentrated to the absorber 260 merged into the brine water to evaporate the water; the vapor generated on the surface of the brine water rise in the house formed by the inner holder 250 and outer holder 220, and arrive at the condenser 240, and get condensed there, then is collected by the collector 230.

[0016] In the preceding specification, various preferred embodiments have been described with reference to the accompanying drawings. It will, however, be evident that various other modifications and changes may be made thereto, and additional embodiments may be implemented, without departing from the broader scope of the invention as set forth in the claims that follow. The specification and drawings are accordingly to be regarded in an illustrative rather than restrictive sense.

[0017] Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the invention disclosed herein. It is intended that the specification and examples be considered as exemplary only, with the true scope and spirit of the invention being indicated by the following claims.
