Application filed March 29, 2915. Serial No. 17,788.
as are set forth in my prior Patent 902,875
for cooling towers bearing date November 3, 1908, and is an improvement on such prior patent. V
Furthermore the invention is an improvement over the aforesaid patent arranged to permit a more efiicient distribution of such trays as are illi'istrated in my prior patents numbered 1,023,564 and 1,0l0,818 respectively.
lhe principal object of thepresent invention is to improve on the means for distributing the water from the delivery piping to the cooling decks whereby equal distribution. is obtained and a maximum contact between the finely divided, water and a maximum of cooling air.
A second object of the invention is to. improve on the arrangement of cooling trays whereby the trays are arranged in sets having double decks with the trays of the upper deck being in staggered relation to the trays of the lower deck in each set, whereby more efficiently to distribute the water dripping down through the sets of trays so that the cooling air may have more eficient access to the water. I
Provision is made in my former Patent 902,875 for certain aprons orspray shields. A third object of the invention is to improve the construction of these aprons or spray shields so. that the supporting'frames for these spray shields may be arranged to.
act as trusses for the main tower.
Furthermore, I have found in the use of my tower, as set forth in Patent 902,875 high wlnds interfere with the proper operation of the device and cause waste of the water.
A fourth object of the invention is to ion-- prove on the construction of such a tower, so that an auxiliary spray preventer in the form of a suitable baille arrangement extends up through-the center of the tower from top to bottom thereof.
A fifth object of the invention consists in the provision of annnproved arrangement of piping provided with ,specia1 nozzles ar or the other of'my Patents ranged to discharge jets of compressed air across the path of the descending water dun ing, the periods when there are no natural i aircinrents, suchas in a calm.
lVith the above and other objects in view as will be hereinafter set forth, the invention consists in general of certain novel de tails of construction and combinations of parts, hereinafter fully described, illustrated in the accompanying drawings, and
specifically claimed.
In the accompanying drawings like charthe parts beneath.
actors of reference indicate like parts in the Fin 2 is a vertical section on the line n-ir of Fig. 1.
Fig. 3 is a perspective view of a portion of the compressed air pipes used herewith and the attached nozzles.
Fig. 4 is a'view, partly in elevation and partly in section of one of the water delivery nozzles used herewith, showing in dotted lines the relation of the trays.
Fig. 5 is a detail showing certain screen plates for the wind screens of theinvention. In carrying out-the objects of the invention there is provided a suitable tower on framework whichmay' be of any preferred cross section or plan arrangement although the frame is preferably rectangular and con-- sists in general of. uprights 10 which rest upon and have secured thereto a drip pan 11. The uprights are connected by horizon tal tic angles 12 upon which rest the I-beams 1.3; the latter being suitably fastened to the r tie dIlglGS.
Extending aiove the upper I-beams are water distributing pipes 14 which a'reconnected to a header 15 leading from a stand pipe 16, the latter receiving. hot water to bdcooled from a suitable source of supply as'the pipe 17.
Each of the. pipes 14 is provided with a series of upstanding nozzle ing a skirt or distributor cone 19,50 arranged that the water flowing out or the nozzles will be spread by the skirts or dis-- 1 8,each carry tributer cones into the trays 20, they latter being, preferably of the type disclosed in. one 1,023,564 or 1,040,318 above referred to.
These trays are arranged in double decked sets, each mt being fixed on the upper and broken up lower flanges of respective horizontal rows of the I-beams 13 and the trays of the upper deck being in laterally staggered relation with the-trays of the lower deck. As described in my former and herein referred U. S. Patents Nos. 1,023,564 and 1,040,318, the water in the pans or trays overflows over the edges of the trays and passes off the support-ing and diffusing ledges to the pans or trays on deck below in two distinct lines instead of one as in the case of flat boards heretofore employed. Furthermore, in the herein disclosed arrangement the water splashes clear of the sides or edges of the pans or trays and forms two more lines of drops, so that by the present disposition of pans or trays, the water is broken up into four distinct lines of drop for every tray or pan in each horizontal group of trays, and hence exposes more surface ofthe water to the cooling influence of the air; than when flat boards are used. 'By this arrangement the sheets of water are so that they amount in practice to a fine spray and the cooling air has access to the minute particles thus insuring rapid and eflicient cooling.
The arrangement of the wind or spray shields in the present device consists of upwardly and outwardly extending supporting members 21, each having its lower end attached directly to the main frame or the drip pan, while its upper part is connected to the main frame by a tie members 21 are connected'by horizontally disposed frames consisting of rods or pipe lengths 23 connected by couplings as turn buckles 24'so that the rods or pipe lengths 23 may be adjusted and each frame may be tightened up and constitutea truss for supporting the main frame from lateral flexure. Sheets 25 forming the spray preventer, are suit-ably fastened together at their vertical edges by lap joints or solder and secured to the pipe lengths 23 by means of wires 26 on all four sides of the frame work of the tower. Said wires 26 pass through the sheets 25 and reinforcing clips 27 placed on the outer side of the sheets 25, as shown in Fig. 5, the innerends of the wires 26 are passed around the pipe lengths 23 and twisted together, thereby firmly holding the sheets 25 forming the spray preventer to the pipe sections 23 and preserving their proper angle and relation to the frame work 10 and the groups of trays 20 at each gallery section in all kinds of weather. edge of each set of these sheets 25 forming the spray preventers or shields is substantially in a plane horizontal with the lower edge of the next set above, so that direct horizontal currents of air are prevented from passing across the down flowing water.
It sometimes happens that, during high winds, even such wind screens as have been cooled.
When there is no wind, or even when there is but very little wind, apparatus of this character frequently becomes defective in operation,
To overcome this defective condition, I provide on each side of the middle battle a vertical air stand pipe 30 connected the water not being sufiiciently to each .other by a branch pipe 34, and to There is also provided 'a suitable ladder 35 which leads up to an inspection gallery 36.
.Thus by a' simple and efficient apparatus provision is made for accomplishing all of the objects hereinbefore set forth.
What I claim is 1. A cooling tower comprising a supporting frame work, a series of water pans or trays arranged at different levels thereon and having means series to another at a lower level, and a series of vertical water distributing nozzles arranged adjacent to and over the upper water pans of the tower, each nozzle being surrounded by a water distributor cone be-.
tween its outlet and the pans.
