Abstract

Abstract A method and apparatus for atomizing and elevating liquids with entrainment of gases therewith, which comprises generating an upwardly spiralling vortex within an elongated substantially vertical duct having an orifice at the top and a nonhorizontal configuration at the bottom defining a bottom orifice, at least a portion of the bottom of the duct being submerged in a reservoir of the liquid. Application of subatmospheric pressure to the interior of the duct results in atomization and elevation of the liquid within the confines of the bottom orifice, optional entrainment of gases therewith and vortical upward movement thereof. The reservoir is maintained at a level such as to keep at least a portion of the bottom of the duct submerged in the liquid.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 32 words
The method of claim 1, wherein the linear velocity of said vortex is at least 1,000 feet per minute, and the ratio of rotational velocity to linear velocity is greater than 1:1.
Claim 2
Dependent Claim 35 words
The method of claim 1, wherein the step of separating liquid from said gases includes agglomerating said atomized liquid after passage through said duct, discharging said gases, and returning said separated liquid to said reservoir.
Claim 3
Dependent Claim 35 words
The method of claim 1, wherein the rotational velocity of the outer confines of said vortex is about 6,000 feet per minute, and wherein the ratio of rotational velocity to linear velocity is about 3:1.
Claim 4
Dependent Claim 292 words
Apparatus for atomizing and elevating liquids and entraining gases therewith, comprising an elongated substantially vertical and substantially cylindrical imperforate uniform diameter duct; orifices at the top and bottom of said duct; said bottom orifice having a nonhorizontal configuration; a reservoir containing a liquid beNeath said duct; means for maintaining the surface of said liquid at a level, relative to said duct, such that a portion of said nonhorizontal bottom orifice is partially submerged in said liquid, the remaining portion of said bottom orifice not being submerged in said liquid providing substantially nonrestricted entry for gases into said duct above the surface of the liquid; fan means positioned closely above said top orifice substantially in axial alignment with said duct, said fan means generating an upwardly spiraling vortex of gases within said duct under conditions of subatmospheric pressure with the rotational velocity of the outer rotating confines of said vortex being between 2,000 and 12,000 feet per minute and of sufficient magnitude to rupture the surface tension of the liquid at rest within the confines of said duct, whereby said liquid is atomized and elevated in said vortex within said duct along with gases drawn through the nonsubmerged portion of said nonhorizontal bottom orifice; and means connected to the top of said duct for removing liquid from said gases after contact thereof with said fan means, a sump housing containing said reservoir including an inlet for gas thereabove, a top closure member for said sump, means securing said duct adjacent its top orifice to said closure member in sealing relation thereto, and an upwardly extending stack sealingly secured to said closure member, said fan means for generating an upwardly spiralling vortex being positioned in said stack in coaxial alignment with said top orifice.
Claim 5
Dependent Claim 25 words
The apparatus claimed in claim 5, wherein the bottom of said duct is cut on a diagonal of from 15* to 75* with the horizontal.
Claim 6
Dependent Claim 52 words
The apparatus claimed in claim 5, wherein said fan means comprises a motor and fan wheel positioned closely above said top orifice and substantially coaxial therewith, said fan wheel having blades at least a section of which directly above said top orifice function in the manner of backwardly inclined centrifugal blower blades.
