UNITED STATES ALBERT W. MORSE, 0F FOREST HILLS, NEW YORK, ASSIGNOR TO THE ANTHONY COM- PANY, OF LONG ISLAND CITY, NEW YORK, A CORPORATION OF NEVKYORK.
NEBULIZER OF LIQUIDS.
Application filed June 21, 1919. Serial No. 305,927.
To all whom it may concern:
Be it known that I, ALBERT W. MORSE, a citizen of the United States, and a resident of Forest Hills, in the county of Queens and State of New .York, have invented certain new and useful Improvements in N ebulizers of Liquids, of which the following is a specification.
This invention relates to nebulizers of liquids, that is, ap aratus for causing liquids, and particu arly fuel-oils and gas oils, to assume the formv of an extremely fine mist; and the invention particularl re lates to nebulizers of the free centri ugal type hereinafter disclosed, wherein the cen trifugal action is obtained, not by moving parts or by stationary baflles in the passage or by the impact of an elastic aeriform liquid, but by the direction of admission into the passage.
Objects of my invention are to distribute the fine mist of liquid over a large area by means of a multiplicity of mechanical atomizing nozzles, functioning by free centrifugal action; to vary the pressure as well as the quantity of discharge flow at nozzles uniformly by means of a unit control; to protect the oil passages by means of a continuous supply of cooling water in order to prevent carbonization of the oil; to inject this cooling water close to the spray cap and to permit it to circulate freely around the multiplicity of passages.
Another important object of this invention is the casting of the oil manifold and spray cap in one piece, thus eliminating numerous joints which are necessary when making the manifold and cap of two separate castings and connecting them by means of nipples. Owing to the rough usage to which the 'nebulizers are subjected when installed and owing also to the variable ex pansion and contraction, -it has been difficult to keep the nipple joints tight. This resulted in high repair costs. The structure described overcomes these objections.
In the drawings, Fig. 1 is a vertical longitudinal sectional view of the nebulizer; Fig. 2 is a cross sectional view along the plane 2-2 in Fig. 1; Fig. 3 is an end view of the nebulizer showing-the location of the spray nozzles; Fig. 4 is another end view of the nebulizer showing a modification in the lo cation of the spray nozzles, and Fig. 5 is an end view of the inlet end of the device.
Like characters of reference denote similar parts throughout the several views .and the following specification.
10 is a hollow cylinder, one end of which is threaded to be screwed into a circular flange 11. The center of flange 11 is bored out to receive an oil supply pipe 12. 13 is a stuffing box gland, adapted to be pressed against packing 14, by means of studs 15 i and nuts 16 for the purpose of making the joint between oil supply pipe 12 and flange 11 pressure tight. 17 and 18 are openings through the flange 11, located within the inside diameter of the cylinder 10, and communicating, respectively, with a water inlet elbow 19 and water outlet elbow 20 which 1 are both screwed into the exterior face of V the flange 11. The outwardly projecting end 21 of oil supply pipe 12 is screw-threaded to receive a control valve of the usual commercial construction (not shown).
22 is. a hollow cup-shaped spray cap or manifold screwed onto cylinder 10. 23 are spray plu s, identical in design with those shown in atent #1,082,777 issued Dec. 30, 1913 to J H. Stringham, which spray plugs are screwed into the outer wall 24 of manifold 22. Within the cap 22 and concentric therewith is a cup 25, internally threaded, adapted to screw onto oil supply pipe 12. Passages 26 connect the interior of cup 25 with the spray plugs 23; the walls forming the passages 26, the outer cup 22 and the inner cup 25 being integral with each other and formed of one casting. Screwed into flange 11 and in communication with water inlet elbow 19 is a water inlet tubes 27,
which terminates near the top of the cylinder 10.-
The operation of my device is as follows:
Oil, under pressure, is introduced through supply pipe 12 and passages 26 to the spray plugs 23, whence it issues in the form of a fine vapor 'or nebula due to centrifugal action and whirling motion as explained in detail in the above mentioned Patent No. 1,082,777. The amount of oil discharged and the pressure thereof is controlled by means of a single valve attached to the outer end of the oil supply pipe 12. To prevent carbonization of the oil, the nebulizer being rod more or less subjected to high temperatures,
a supply of cooling water is introduced into cylinder 10 through inlet elbow 19 and tube 27, close to the spray cap 22. This cooling water circulates around the assages 26 leading to the spray plugs an all around the oil supply pipe 12, and is then forced out through the elbow 20, efiectively preventing undue heating and subsequent carbonizing of the oil.
In Fig. 3 is shown an arrangement of the spray nozzles intended to spray an area of substantially circular configuration, while the manner of locating spray nozzles shown in Fig. 4 is to be used for covering areas of rectangular or oval shape.
Various changes in the form, proportion I and minor details of construction may be resorted-to without departing from the principle or sacrificing any part of the invention as defined in the appended claims.
- with said water jacket.
2. In a nebulizing device, an inlet passage for the liquid to be nebulized, a manifold at the discharge end of the said inlet passage, a multiplicity of outlet nozzles, the said manifold connecting the said inlet pas sage with the said outlet nozzles, a jacket surrounding the said manifold and inlet passage, said jacket being closed at one end'by a cap comprising the said manifold, a support for the said outlet nozzles and circulating passages around the said manifold" in communication With the said jacket.
3. In a nebulizing device having a 'multi plicity of outlet nozzles, an inlet passage for the liquid to be nebulized, a cooling fluid circulator surrounding said passage, a cap to close one end of said circulator, said cap integrally comprising a manifold. circulating passages for said cooling fluid, and a slllpport for the multiplicity of outlet nozz es.
4. In a nebulizing device, a passage for the liquid to be nebulized, a. cooling fluid circulator surrounding said passage, and a cap to close the outlet end of said circulator, said ca 7 integrally containing a manifold, a multip icity ofoutlet nozzles, the said manifold connecting the said inlet .passage with v the said outlet nozzles, as well ascircuIating passages within the said ca and around the said manifold for said cooling fluid.
In testimony whereof I have hereunto set my hand and seal in presence of two subscribing witnesses.
