Abstract
Abstract Spraying apparatus is provided which employs a porous member through which a liquid is forced and is caused to be disspelled from a surface thereof as a spray or atomized particles. In one form, liquid is forced from a first chamber through a porous wall or plug to the outer surface thereof by applying pressure directly to the liquid and, upon emerging on said outer surface, one or more jets of high velocity gas are directed against said outer surface to lift and atomize the liquid and direct same as a spray into the surrounding atmosphere. In another form, liquid is admitted to a chamber having a porous wall portion and one or more jets of high-velocity gas are directed from the exterior of said chamber through the porous wall portion, into the liquid therein and through a second portion of the wall of the chamber which is also porous. The gas acts to force liquid in the chamber through the second portion of the wall thereof and beyond the chamber as an atomized spray. The apparatus is particularly applicable for atomizing, and in certain instances, vaporizing liquid introduced over a substantially large surface area without the need for precisely machined nozzled devices.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
131 words
Spraying apparatus comprising: a. a first conduit, b. a wall portion of said first conduit being made of a porous material having passageways communicating between the inside and outside surfaces of said wall portion, c. a second conduit disposed adjacent to said first conduit, d. an opening in said second conduit, e. means for introducing a liquid under pressure to said first conduit, f. means for introducing a gas under pressure to said second conduit, g. said opening in said second conduit being directed and disposed so as to direct said gas through the porous portion of the wall of said first conduit, said gas being under sufficient pressure to force liquid in the porous wall of said first conduit away from the exterior surface thereof as a spray or mist.
Claim 2
Dependent Claim
131 words
Spraying apparatus comprising: a. a first conduit, b. a wall portion of said first conduit being made of a porous material having passageways communicating between the inside and outside surfaces of said wall portion, c. a second conduit disposed adjacent to said first conduit, d. an opening in said second conduit, e. means for introducing a liquid under pressure to said first conduit, f. means for introducing a gas under pressure to said second conduit, g. said opening in said second conduit being directed and disposed so as to direct said gas through the porous portion of the wall of said first conduit, said gas being under sufficient pressure to force liquid in the porous wall of said first conduit away from the exterior surface thereof as a spray or mist.
Claim 3
Dependent Claim
52 words
Apparatus in accordance with claim 1, said second conduit having a plurality of closely spaced holes extending through the wall portion thereof adjacent to said first conduit and each operative to direct a high-velocity stream of gas through said first conduit to force liquid from the porous wall of said first conduit.
Claim 4
Dependent Claim
77 words
Apparatus in accordance with claim 1, said second conduit extending through the interior of said first conduit, said porous material terminating at the end of said first conduit, said second conduit having its open end terminating against the inside face of said porous material at sufficient velocity to cause liquid flowed through the porous material from said first conduit to be dispensed from the outer surface of said porous material as finely divided particles of said liquid.
Claim 5
Dependent Claim
49 words
Apparatus in accordance with claim 1, including means for heating said gas to a high enough temperature prior to flowing said gas from said second conduit to cause the liquid of said first conduit to be come vaporized as it leaves the porous wall portion of said first conduit.
Claim 6
Dependent Claim
105 words
Fluid processing apparatus comprising: a. a first conduit having opposite wall portions made of porous material, b. a second conduit disposed adjacent to said first conduit, c. an opening in said second cOnduit, d. means for introducing a liquid under pressure to said first conduit, e. means for introducing a gas under pressure to said second conduit, f. means for directing high-velocity gas from said opening in said second conduit through the opposite porous wall portions of said first conduit to force liquid in said conduit through the porous wall thereof and to introduce said liquid as a finely divided spray beyond said first conduit.
Claim 7
Dependent Claim
105 words
Fluid processing apparatus comprising: a. a first conduit having opposite wall portions made of porous material, b. a second conduit disposed adjacent to said first conduit, c. an opening in said second cOnduit, d. means for introducing a liquid under pressure to said first conduit, e. means for introducing a gas under pressure to said second conduit, f. means for directing high-velocity gas from said opening in said second conduit through the opposite porous wall portions of said first conduit to force liquid in said conduit through the porous wall thereof and to introduce said liquid as a finely divided spray beyond said first conduit.
Claim 8
Dependent Claim
48 words
Apparatus in accordance with claim 5 including means for heating said gas to a high enough temperature prior to flowing said gas from said second conduit to cause the liquid of said first conduit to become vaporized as it leaves the porous wall portion of said first conduit.
Claim 9
Dependent Claim
163 words
Spraying apparatus comprising: a. a first conduit, b. a wall portion of said first conduit being made of a porous material having passageways communicating between the inside and outside surfaces of said wall portion, c. a second conduit disposed adjacent to said first conduit, d. a plurality of holes in the wall of said second conduit, e. means for introducing a liquid under pressure to said first conduit, f. means for introducing a gas under pressure to said second conduit, g. said plurality of holes in the wall of said second conduit being disposed so as to direct a plurality of high velocity jets of gas from said second conduit above the exterior surface of the porous wall portion of said first conduit with each jet of gas being operative to pick up and dispense a film of said liquid formed on the exterior surface of said first conduit as an extended sheetlike spray of particles of said liquid beyond said first conduit.
Claim 10
Dependent Claim
163 words
Spraying apparatus comprising: a. a first conduit, b. a wall portion of said first conduit being made of a porous material having passageways communicating between the inside and outside surfaces of said wall portion, c. a second conduit disposed adjacent to said first conduit, d. a plurality of holes in the wall of said second conduit, e. means for introducing a liquid under pressure to said first conduit, f. means for introducing a gas under pressure to said second conduit, g. said plurality of holes in the wall of said second conduit being disposed so as to direct a plurality of high velocity jets of gas from said second conduit above the exterior surface of the porous wall portion of said first conduit with each jet of gas being operative to pick up and dispense a film of said liquid formed on the exterior surface of said first conduit as an extended sheetlike spray of particles of said liquid beyond said first conduit.
Claim 11
Dependent Claim
103 words
Apparatus in accordance with claim 6, said second conduit being disposed within said first conduit, and a porous member terminating the end of said first conduit and tapering inwardly therefrom, closure means at the end of said first conduit, a plurality of openings in said closure means extending around and peripheral of said porous member, said openings being directed so as to direct a plurality of high-velocity streams of gas over the surface of said porous member to lift liquid flowed to said surface and to generate finely divided particles of said liquid in the volume beyond the end of said porous member.
