FRUTI-I, or cIIIoAGo, ILLINOIS, AssIenoR To weare 'sn' ncr c "oer/ream, INCORPORATED, OF NEW YORK, N. Y., A CORPORATION 01 NEW YORK LIQUID SPRAY DEVICE Application filed December 10, 1930.
This invention relates to liquid spray devices, and more particularly to devices wherein a liquid and a gas are brought into contact for the purpose of purifying the gas or for other purposes. D
An object of the invention is to provide a liquid spray device of simplified construction which shall be inexpensive to manufacture and which is non-clogging and may be #1 readily inserted in and removed from a gas conduit.
In its preferred form, the invention comprises a liquid conduit mounted within a gas conduit and having attached to its discharge end a deflector designed to deflect the liquid into the form of a circular sheet which extends transversely of the gas conduit, so that the gas passing through the gas conduit is necessarily brought into contact with the sheet of liquid. The construction of the deflector is of a simplified non-clogging design, and its maximum diameter is approximately the same as the diameter of the liquid conduit, which facilitates the assembling and disassembling of the apparatus.
The invention will be more fully understood from the following description, taken in connection with the accompanying drawing, in which Fig. 1 is a sectional view of adevice embodying the invention, showing the liquid conduit in elevation;
Fig. 2 is a vertical sectional View taken on the line 22 of Fig. 1;
Fig. 3 is a view of the liquid conduit and deflector as viewed from the bottom of Fig. 2, and
Fig. 4 shows the deflector in an intermediate stage of manufacture.
Referring now to the drawing, the device comprises a gas conduit through whicn gas may be passed either upwardly or downwardly as desired. Secured within the conduit 10 by any suitable securing means (not shown) is a liquid conduit 12, the lower end of which is slotted at diametrically opposite poin'ts as indicated at 14 to receive a deflector 16. The deflector has a pair of spaced upwardly extending integral arms 18 which fit into the slots 14 and are preferably secured therein Serial no; 501,225.
by pinching the end of the conduit 12 to compress the arms rigidly in position, although soldering, welding or other means may be employed for securing the arms in'place.
As shown in Fig. i, the deflector is formed from a sheet metalblank, by stamping or otherwise, the ends ofthe blank being roundthe opposite end of the aperture to holdthe arms 18 rigidlytogetherl lVhen assembled, the transverse dimensions of the deflector should be substantially equal to tire transverse dimensions of theconduit 12, and-the baffles 20 should be spaced from thelower end of the conduit 12 by a distance :not' substantially less than said transversedimensions.
In operation, water-or other liquid is passed downwardly through the liquid conduit 12 and strikes the baffles 20-which form-it into a circular sheet which extends over the entire cross-section of the gas conduit 10, sotha-t gas passing therethrough necessarily contacts with the liquid ofthe sheet.
The device may be advantageously used as a sparkarres'ter in 'connection with a flamemaking wire enameling apparatus, in which case the gas conduit 10 will convey exhaust gases from the apparatus, some of which gases may be the products of incomplete combustion and therefore explosive, and the gases may also contain some floating particles of burning solid matter, which will be extinguished by the sheet of liquid produced by the ballies 20. The liquid employed in such case will ordinarily be water, and it is frequently desirable to circulate the water over and over again, which causes the liquid to accumulate a certain amount of scum and other solids collected from the gases. With the device of the present invention, however, such solids do not collect at the deflector nor obstruct the same, since any solid matter which will pass the conduit 12 will also pass the deflector. This is because the width of 100 the aperture 22 is the same as the inner diameter of the liquid conduit 12, and because the bafiles 20 are spaced from the lower end of the conduit 12 by a distance not substantially less than said inner diameter.
In addition to its use as a spark arrester, the device may be used for purifying or cooling gases, or in any relation where it is de sired to bring a gas and a liquid into contact. The invention is therefore not limited to the precise constructional and functional features above described, but may be modified without departing from the spirit thereof as defined in the following claims.
15 What is claimed is:
1. In a liquid spray device, a liquid conduit having a slotted end, and a deflecting member secured to said end and comprising arms fixed in the slots of the liquid conduit and bafiles positioned in alinement with the conduit, said arms extending beyond said conduit and lying substantially wholly be tween the extended interior and exterior surfaces of the conduit wall and said baflles having an area substantially equal to the crosssectional area of the conduit.
2. A liquid spray device comprising a cylindrical open ended pipe and a transverse baffle spaced from the end of the pipe and supported solely by connections lying substantially wholly inside the extension of the outer surface of the pipe and outside the extension of the inner surface of the pipe, the end of said pipe being slotted and said connections consisting of arms secured within said slots.
3. A liquid spray device comprising a pi e having a slotted end and a sheet metal ba e having abutting semi-circular portions and integral side strips folded to form supports, the bights of said folds being secured in said slots.
