SOLAR DESALINATOR WITH PARABOLIC-CYLINDER REFLECTORS Russian patent published in 2018 - IPC C02F1/14 

FIELD: water treatment.

SUBSTANCE: invention relates to devices for distilling mineralized, contaminated or sea waters by using only solar energy for heating water. Solar desalinator contains a sun concentrator on parabolic cylindrical reflectors equipped with consoles with holes in which evaporating tubes are placed located in the focus of the reflectors, and the system for tracking the sun consists of a hydraulic cylinder, the rod of which is mechanically connected to its piston and through levers with cantilevered brackets, a sealed tank containing mineral oil with a working fluid and an oil pipe connecting the hydraulic cylinder to the tank, wherein the condenser with the distillate collector is made of a transparent body partially submerged in a reservoir of desalinated water, and contains a heat-accumulating material with an additional evaporating surface, above which is located one end of the steam pipeline, its other end is connected to the outputs of the evaporating pipes, the inputs of the latter are connected via a conduit to a reservoir of desalinated water. Evaporative tubes are enclosed in transparent outer shells, from which air is pumped out, and on the side of the sun on the shells are placed mirror reflectors along their entire length and half the diameter of the evaporating tubes. In the upper area of the condenser housing is placed a condensate moisture collecting grid, fixed on the sides of the body. Removable heat-resistant fabric is placed on the additional evaporator surface and on the inside surface of the evaporating tubes.

EFFECT: invention provides a simplified design and increased reliability of the desalinator and its productivity.
