THE SOLAR DISTILLATION OF WATER (La Distillation Solaire des Eaux)

摘要

The solar furnace for distilling sea water is characterized by the fact that it consists of a large-area horizontal rack located a certain distance above the ground, a foundation which is made up of juxtaposed panels that can be turned toward the bottom to recover salt deposits, and which is topped by a metal grating in which links are situated at regular intervals, and convergent lenses at an appropriate focal distance, above which inclined elongated mirrors are arranged; of these the largest area is north-south oriented. The forms of the realization of a solar furnace are characterized by the following points, either alone or in combination: the horizontal rack consists of the solar furnace properly supplied with sea water by nozzles, preferably cylindrical, joined to the sides by a divergent member made of reinforced concrete and eventually by the intermediary of aspiration pumps; the produced steam is aspirated in a large expansion chamber which is connected to the side of the rack opposite the divergent member and extending member from a convergent member which feeds a condenser; Pipes, preferably made of brass, are interconnected to form a coil for generating steam and are situated on the bottom of the horizontal rack, making up at least a part of the longitudinal equipment; the steam generated by the coil furnishes the power to drive a thermal power station which supplies the auxiliary machines of the installation, particularly the condenser and the aspiration pumps.
