Application fled July 25, 1925,
The present invention relates to an apparatus for atomizing liquids.
In atomizing liquids it is known to conduct the liquid to be atomized to a rapidl revolving disc on which the liquid, under the influence of the centrifugal force and according to its viscosity and elasticity will be spread out in form of a thin film. It is also known to atomize liquids bv blowing them by aid of compressed air through a small orifice or slit.
It is the object of this invention to construct the apparatus forming the sub'ect matter of the present invention in sue a manner that its operation may be considered as a combination of the two known methods of working mentioned, and by such combination a special effect may be secured.
e apparatus is characterized chiefiy'by an upper inverted stationary hollow truncated conical conduit, the ower edge of which is sharp, and a lower dish coaxial with said cone, arranged to be revolved at a high speed and having its inside turned out to a paraboloid form. The upper edge of this lower dish is likewise made sharp and is disposed slightly below the said lower edge of the cone, the diameter of the dish bein substantially that of. the discharge end of the conduit, so that there will always remain between the cone and the dish a comparatively narrow gap through which the liquid to be atomized will be thrown by centrifugal force. 1
The accompanying drawing is a vertical sectional view showing the apparatus described in a constructlonal form.
1 is a stationary, inverted hollowtruncated conical conduit, the lower edge 2 of which is be made sharp. Beneath this inverted hollow cone 1 is disposed, coaxially therewith, a concave plate or dish 3, the inner surface of which is turned out to-a paraboloid, the upper edge 4 of this dish being likewise made sharp. This edge is disposed a little below the knife edge 2 of the inverted cone 1 and is, in the constructional form shown in the drawing, immediately below this edge 2. The arrangement may, however, also be so that the upper edge 4 of the dish is disposed slightly within or slightly outside of the lower edge 2 of theinverted cone. The dish 3 is secured to the dish and the inverted cone. This spindle may, as shown, extend upwards through the inverted cone 1, or it may extend downuid by producin Serial m. 40,110, and in Denmark no, as, m4.
ward from the dish,
y duced between the stationary inverted cone 1 and the dish. 3 revolving through which ap the liquid to be atomized can emerge. 1 the constructional form shown in the drawing with spindle 5,
the liquid to be atomthat it serves at the same time as liquid supply pipe. Whether one or the other of these arrangements be employed, the conditions should be such that he liquid runs into the dish as near as possible to its axis whereupon it will from this point be deposited in the deepest portion of the dish. B suitable means compressed air is introduce into the inverted cone 1, and, as shown in the drawing, the flow of the compressed air has been indicated by arrow. 1 he operation of the apparatus is as folows:
The liquid which is conducted to the dish will when the dish revolves at a high speed, spread in an even film over the face of said dish, partly under the action of the centrifugal force, partly owing to the paraboloid form of that surface which causes a suction downwards along the spindle and a blast outwards at the upper edge 4.
Furthermore the I duced into the apparatus, will act on the liqwithin the gap between the lower edge 2 o the inverted cone and the upper edge 4 of the dish a ring of highly compressed air, the lower side of which wiH- revolved with the dish 3, while its upper side will be pressing against the stationary cone 1 and will therefore be practically stationar These peculiar conditions will have the ala that the compressed air emerging through the gap will, outside of the latter, form eddies in the air. The film of liquid spread on the paraboloid surface of the dish will emerge from apparatus through the said ap partly under action of the centrifugal orce and partly under the force of the compressed air, and the liquid or the film of ii uid leaving the apparatus is immediatelyslibjected to a violent disruption as it becomes mixed with the air and passes from the high pressure prevailing within the a low pressure outside of t e aratus into the utter. The thereby produced fine particles inner sur-- compressed air, introof liquid are, therefore, eddies mentioned, and fact that the liquid i on its emerging i posed to a peculiar efiect produced by the combined action of the rapidly revolving dish and the stationary cone, individually made to rotate on their own axes. This rotation of the fine particles of liquid has the efiect of producing a arrangement of their mol es. It is therefore possible to arrang that the fine partichs thus produced 13 the ato efiect may each individu ybeenvelo byathinfilmofa preservin medium w 'chhasbeen added to the liqui and which has a great r specific gravity than the same.
By va the volume of compressed air supplied 1n proportion to the width of the made it may, furthermore, be ible to expose the liquid to a strong electric action at the moment when it is emerging through the gap between the inv rted cone and the dish. This may for many liquids have a high conserving value, and it also has an influence on the placing of the molecules within the individual particles of liquids.
Having now particularly described ascertained the and in what manner the same is to be performed, I declare, that what I claim is:
1. An apparatus comprising in combination, a concave plate, means for supplying compressed air to sai plate, said means comprising a truncated and conical conduit tapering toward said plate and terminatin in proximity d plate, the diameter 0 the end of said conduit adgap it is posslble to te the rotation of iacent the plate bein substantially equal to the fine articles of liquid mentioned and the diameter of sai plate and m coaxial thereby the arrangement of the mole alignment therewith, means for supplying a cules of liquid within the individual parliquid centrally of said plate, and means or ticles The said rotation may even be made rotating said plate.
5 so great that the individual particles of liquid areqfigli n-H toadisruption (a secondary ption) so that by such means fiect willbe a specially fine choosing the materials of h and the inverted cone are 2. An apparatus as claimed in claim 1 said plate being parabolic in section.
3. An apfilaratus as claimed in claim 1 said plate and e dischar end of the conduit being provided with arpened edges.
