Description

SYSTEM FOR LIFTING WATER IN VAPORIZED S TATE FOR GREAT DISTANCES The present invention relates to a system for lifting wate in vaporized up a hillside for condension storage at a considerable height above the water Most prior water distillation equipment includes complex arrangements of heaters and pumps to boil and circulate the Prior solar heated systems are usually of low capacity and often use pumps to move the The system shown and described herein is by solar energy once in yet is capable of purifying and lifting a large volume of water to a reservoir on order of several thousand feet above the water The structure of the apparatus is very simple and the entire length of the water lifting duct from source to the reservoir may be subjected to solar heating for maximum In the 1 is a diagrammatic view of the basic 2 is an enlarged sectional view taken on line of is a diagrammatic partly in section of the complete is an enlarged sectional view taken on line of is an enlarged sectional view taken on line of and is a sectional view taken on line of In the system shown in the water vapor is collected in a hood 10 over source of water and fed into a duct For the hood is suspended over a convenient area of a polluted lake or Duct 14 is an 18 which closes the Inside the duct is a pipe 19 which carries the water pipe extending the full length of the duct and being supported at the focus of concave reflector for maximum In a practical installation the duct would extend up a hillside with required suitable for a considerable on the order of a mile or to a reservoir well elevated above the water At the uppe end of the duct the pipe 1 is connected a condenser 21 which discharges into a suitable condenser bein described Since there is a high of vapor in pipe the vapo may be used to drive an air motor which can be used to operate condense or to drive an electrical generator as an added This the simple basic and is completely with solar energy heating Efficiency of the system may be increased by the arrangement shown in in which a pipe 22 is mounted on supports at focus of reflector 16 the pipe starting at the lower end of the duct and extending the length of duct a delivery pipe 26 at reservoir At spaced intervals the pip 22 is interrupted to provide the upper end of each section of pipe having a tapered nozzle 30 which into the lower end 32 of next length of When the pipe 22 is heated by energy the vapor therein will rise and increase At each interruptio in the pipe the vapor is accelerated through the nozzle 30 causin a pressure drop entrains also solar periodicall entrains further vapor along the duct and results in a high mass flow at the upper The upper end of duct is closed to prevent loss of thus creation of draught preventing and any cooling in the duct It has been found that even a short length of and pipe structure as a very considerable flo of vapor at high velocity can be generated with reasonable solar Parts or all of the duct can be made movable to follow the apparent motion of the the technique being well known in solar energy Over the long distance plated for a fully operable the flow of vapor would contain considerable kinetic which can be used to make the system and under The condenser can be equipped with a check valve and fed from the bottom but the condenser illustrated in and is particularly effective with this because generates a negative back pressure at the upper end of the pipe 19 the duct thus enhancin r delivery pipe 26 is connected through rotary couplin of any suitable to a centrifugal denser which is immersed at a substantial depth the water of the The condenser as has a central cylindrical sleeve on the lower end of which affixed a radially extending circular plate the upper end of said sleeve being freely rotatable in coupling Coaxial with sleeve is a shaft on the lower end of which a radially extending circular plate as being radial could be or curved for more efficient centrifugal propulsion The lower end of sleeve has an opening through plate 42 chambe between the the chamber having a peripheral outlet between the edges of the Above plate 2 is a shallow conical upper cap 5 inlet openin 5 concentric with sleeve 40 and enclosing a chamber 60 which tapers outwardly to narrow peripheral above inlet Upper cap 56 is secured to plate 42 by vanes 64 which are shown as bein radial but could be Inclined or The inlet opening has circumferential blades 66 projecting radially inwardly and twisted to scoop water into chamber 60 when the condenser rot Below plate 46 is shallow lower cap 68 enclosing a water chamber with a narrow peripheral outlet 72 below 5 Lowe cap 68 is attached to plate 46 by vanes 74 and has a central inlet opening 7 blades 78 scoop In plates and 46 near the outer are ports 80 connecting the chambers 60 and 70 with the peripheral portion of chamber Mounted on shaft 44 at a suitable position in sleeve is a yaned impeller 82 for deriving rotational power from the vapor For starting operation of the the condenser 38 rotated by a motor 84 which may above the water as or be a submersible type mounted above coupling This causes water to be drawn through 58 and 76 into chambers 60 and and centrifugally from outlets 62 and Vapo from delivery pipe 26 generated by energy as the taper chambers 60 and 70 the water flow is accelerated resulting in a pressure drop at the Outlets 62 and 72 thus effectively with outlet an annu venturi providing jet pump action by which the vapor is effectively extracted and distributed into the surrounding water while combination of centrifugal and jet pump action is sufficient to overcome the pressure of the surrounding even at some so that there is no back into the vapor With the system in full operation the flow of vapor becomes sufficient drive the condenser by of the impeller and motor 8k can be shut of so that the system is Back pressure on the vapor column due to driving the condenser is minimized by a pressure drop at outlet This caused by water passing through ports and initiating condensation at the periphery of chamber resulting in a considerable reduction in volume and pressure as vapor changes to In the condensed purified water centrlfugally thrown more eciently into the surrounding than hot would By condensin and mixing the water at unnecessary heating of the surface layer of the reservoir is avoided and further evaporation is The operation can be made if the depth of the condenser is at least so that the back pressure is reduced and then relatively lowered to greater depth for increased this relative lowering being possibly accomplished by lowering the level insufficientOCRQuality
