Method and apparatus for scrubbing gas

Claim 2

Apparatus for scrubbing gas including a hollow outer housing circular in cross section having an inlet end and an outlet end, an inner housing shaped substantially into a cone mounted coaxially within and radially spaced from said outer housing with the apex of the cone facing toward said inlet end thereby constituting a baffle for conducting gas entering the inlet along an annular path between said outer housing and said baffle, said baffle having the circumferential edge thereof opposite said apex lying in a plane normal to the common axis of said baffle and said outer housing, a wheel having a diameter substantially equal to the diameter of said circumferential edge rotatably mounted on said axis, said wheel being positioned with the peripheral edge thereof closely adjacent said circumferential edge and having a plurality of circumferentially spaced radial pipes extending from the hub thereof, means for rotating said wheel, and means for feeding liquid into said hub and through said pipes, whereby upon rapid rotation of said wheel and simultaneous emission of liquid from said pipes a rapidly rotating curtain of liquid extends across said path, said outer housing having a drain positioned between the plane of said wheel and said outlet end, said outer housing having a portion of the surface thereof on both sides of said plane cylindrical, said baffle having a portion of the surface thereof adjacent said circumferential edge thereof cylindrical, and a plurality of circumferentially spaced webs extending between said cylindrical portions thereby providing circumferentially spaced ducts in said annular path adjacent said curtain of liquid, said webs being inclined at an acute angle to said plane in a direction counter to the direction of rotation of said wheel.

Claim 3

Apparatus according to claim 3, having an additional cylindrical inner housing mounted coaxially with said baffle and having the same diameter as said cylindrical portion of the baffle, said additional inner housing being positioned with one circumferential edge thereof closely adjacent the periphery of said wheel on the side of the wheel opposite said baffle, and a plurality of additional circumferentially spaced webs extending between said cylindrical portion of said outer housing and said additional inner housing, said additional webs being inclined at an acute angle to said plane in a direction consonant with the direction of rotation of said wheel.

Claim 4

Apparatus according to claim 4, said additional inner housing having a substantially cone-shaped extension extending from the other circumferential edge thereof in a direction toward said outlet end of said outer housing. said 6. Apparatus according to claim 5, said inlet and outlet ends of said outer housing having smaller diameters than said cylindrical portion thereof, the walls of said outer housing between said cylindrical portion thereof and said inlet and outlet ends thereof being substantially frustoconical in conformation.

Claim 5

Apparatus according to claim 3, said wheel having an each side thereof a frustoconical shield covering said pipes.

Claim 6

Apparatus for scrubbing gas consisting of an outer housing substantially circular in cross section having an inlet end and an outlet end, a coaxial inner housing positioned within and radially spaced from said outer housing, each of said housings having a portion thereof spaced from the ends thereof cylindrical, the cylindrical portion of the inner housing being positioned radially inward from the cylindrical portion of the outer housing, said inner housing having a circumferential gap between the ends of said cylindrical portion thereof dividing the inner housing into two opposed parts, a first plurality of circumferentially spaced webs extending between said cylindrical portion of the outer housing and that part of the cylindrical portion of said inner housing which is on the side of said gap facing said inlet end, a second plurality of circumferentially spaced webs extending between said cylindrical portion of the outer housing and the cylindrical portion of the inner housing on the opposite side of said gap, the end of said inner housing which faces said inlet end being shaped substantially into a cone, a wheel rotatably mounted on the common axis of said housing, said wheel having a diameter substantially equal to the diameter of said cylindrical portion of the inner housing and being positioned in the plane of said gap, said wheel having a hollow hub and a plurality of circumferentially spaced radial pipes leading from said hub, means for feeding liquid into said hub and hence said pipes, and means for rotating said wheel, said first plurality of webs extending at an angle to said plane in a direction counter to the direction of rotation of said wheel, said outer housing having a drain positioned between said outlet end thereof and said gap.

Claim 7

Apparatus according to claim 8, said second plurality of webs extending at an angle to said plane consonant with said rotational direction of the wheel.

Claim 8

Apparatus according to claim 9, the end of said inner housing which faces said outlet end being shaped into a cone, the portions of said outer housing between said cylindrical portion thereof and said inlet and outlet ends being frustoconical in conformation.

Claim 9

Apparatus according to claim 10, said drain being positioned at the bottom of the outer housing adjacent the frustoconical portion thereof and being oriented to said rotational direction of said wheel.
