JEROME B. BLANCHARD, OF DENVER, COLORADO. I

SOLAR EVAPORATOR.

fiPEGIFIGATION forming part of Letters Patent No. 737,551, dated August 25, 1903.

Application filed June 17,1903. Serial No. 161,919. (No model.)

To all who/:2, it ifl/ by concern.-

Be itknown that I, JEROME B. BLANCHARD, a citizen of the United States of America, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Solar Evaporators; and I do declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to means for the evaporation of water by solar heat.

The special object which I have in view for the utilization of the invention is the production of salt in a finely-disintegrated condition,whereby the expense incident to grinding the crystallized product, as is required when evaporation is effected under ordinary conditions, is avoided.

Myimproved apparatus consists of a tower upon which is mounted a tank or reservoir connected with a stand-pipe through which salt water may be pumped into the tank. This tank is provided with a depending outlet leading to aline of spray-nozzles, from which water is discharged downwardly in a finelyatomized condition in front of a refiectingsurface,whereby the spray is subjected to the heating action of both the direct and reflected solar rays. In this manner the finely-atomized water is evaporated and the salt is precipitated in a finely-disintegrated condition. The spray pipe is in communication with another pipe through which air or steam may be forced to facilitate the atomizing function when the pressure from the storage-tank is not sufficient to accomplish the desired result.

Having briefly outlined my improved construction, as well as the objects to be attained thereby, I will proceed to describe the same in detail, reference being made to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure l is a view of my improved solar evaporating apparatus. Fig. 2 is a front view of the same or a View taken in the direction of the arrow in Fig. 1.

The same reference charactersindicate the same parts in both views.

Let the numeral 5 designate a suitable upright frame or supportupon which is mounted a tank 6, into which the saltwater is pumped by way of a stand-pipe 7. This stand-pipe is connected with apumping-engine 8. Connected with the lower portion of the tank 6 at or near its bottom is a depending outletpipe 9, provided with a valve 10 for regulating the quantity of the discharge from the tank. Connected with the lower extremity of this pipe is a horizontally-arranged pipe.

12, provided with a series of spray-nozzles 13. This spray-nozzle pipe is supported in front of the upper part of a reflecting-surface 14, composed of any suitable material, as polished metal. This reflecting-surface should be advantageously arranged or positioned to receive the rays of the sun. Connected with the pipe 9 just above the spraypipe is another pipe 15, which may be utilized for delivering air or steam to the spraypipe, whereby the atomizing of the water is facilitated. This pipe 15 is provided with a controlling-valve 16. The top of the storagetank is preferably closed hermetically in order to prevent the possibility of the escape of the air or steam under pressure by way of the tank.

From the foregoing description the use and operation of the apparatus will be readily understood. The salt water spray being directed downwardly in front of the reflectingsurface, the liquid being in a finely-atomized condition, is evaporated and taken up by the atmosphere, while the salt contained in the water is precipitated and falls into a suitable receptacle or upon a suitable support placed in front of the reflecting-surface. The tank 6 may be elevated to any height that may be found necessary in order to insure complete evaporization of the water sprayed downwardly in front of the reflecting-surface, as heretofore explained.

Attentionis called to the fact that the atomized jets issuing from the spray-nozzles may be directed upwardly instead of downwardly,

if desired' The upward direction of the said jets may be preferable, since to this extent the water will be elevated and its downward movement thus to some extent retarded, since, as heretofore explained, it is necessary that the water shall be sufficiently elevated to give the rays of the sun acting thereon sufficient time to completely evaporate the liquid.

Having thus described my invention, what I claim is 1.. In a solar evaporator, the combination .of a reflecting-surface, and means for delivering water in a spray or finely-atomized condition, in front of the said surface, whereby it is subjected to the evaporating influence of the direct and reflected solar rays.

2. The combination with a tank or storagereservoir suitably elevated, a spray-pipe connected with the tank, and a reflecting-surface located in the rear of the spray issuing from the spray-pipe.

3. The combination with a reservoir or storage-tank, of an outlet leading downwardly from the said tank, a spray-pipe connected with the said outlet, and a reflecting-surface located in the rear and in suitable proximity to the spray-pipe.

4. The combination with a suitable support, a storage-tank mounted thereon, a supply-pipe connected with the tank, an outletpipe also connected with the .tank, a spraypipe connected with the outlet-pipe, a reflecting-surface located in the rear of the spraypipe and a pipe'for delivering air orsteam to the spray-pipe, to facilitate the atomizing of the liquid.

In testimony whereof I affix my signature in presence of two witnesses.

JEROME B. BLANCHARD.
