Abstract
Abstract An air pollution abatement apparatus for removing soot and noxious materials comprising means for delivering a finely divided mist and ultrasonic vibrations into an exhaust for absorbing and rendering more soluble in the mist various noxious materials. A de-mister including a pair of adjacent screens and header means for delivering water between the screen is provided for disposal of the noxious materials.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
147 words
An air pollution abatement apparatus for removing soot and noxious material from gases comprising a conduit for receiving gases to be scrubbed, a disposal tube communicating with and extending normal to said conduit, fluid disposal means connected to said disposal tube, spray nozzle means mounted in said conduit spaced from and in alignment with said disposal tube and including means for simultaneously delivering a mist in a fine spray into said conduit and across the path of said gases and into said disposal tube for separating soot and noxious material from said gases and for directing said soot and noxious material into said disposal tube, a waterfall below said disposal tube and between said disposal tube and said fluid disposal means for demisting said gases, said spray nozzle means being located in advance of said waterfall, and a clean gas dispersal conduit connected to said disposal tube.

Claim 3
Independent Claim
225 words
An apparatus for removing soot and noxious material from gases comprising a conduit for receiving gases to be scrubbed, a disposal tube communicating with and extending normal to said conduit, fluid disposal means connected to said disposal tube, first spray nozzle means mounted in said conduit spaced from and in alignment with said disposal tube and including means for simultaneously delivering in a first flow pattern a gas, a liquid and ultrasonic vibrations into said conduit and across path of said gases and into said disposal tube for separating soot and noxious material from said gases and directing said soot and noxious material into said disposal tube, second spray nozzle means mounted in saId disposal tube and including means for simultaneously delivering in a second flow pattern normal to said first flow pattern a gas, a liquid and ultrasonic vibrations into said disposal tube further wetting soot and noxious material carried in said first flow pattern and for directing said further wetted soot and noxious material into said fluid disposal means, a waterfall below said disposal tube and between said disposal tube and said fluid disposal means for de-misting said gases, said waterfall extending transverse to said fluid disposal means, said first and second spray nozzle means being located in advance of said waterfall, and a clean gas dispersal conduit connected to said disposal tube.
