Abstract
Abstract An improved smogless incinerator for combustible waste materials includes a plurality of chambers through which the combustion products are drawn for successive filtering. The combustion products are filtered through a liquid which is maintained in a turbulent condition by forced air bubbling through the liquid along with the combustion products to assure complete entrapment of the partial combustion products within the liquid.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
153 words
Incinerator apparatus for disposing of combustible waste material, the apparatus comprising: a combustion chamber having an inlet for admitting combustion air and having an outlet; a plurality of fIlter chambers, each having a gas inlet and a gas outlet; first duct means connecting the outlet of the combustion chamber to the gas inlet of one of said filter chambers; second duct means connecting the gas outlet of said one filter chamber and the gas inlet of another filter chamber; at least one of said filter chambers including a quantity of liquid therein which covers the gas inlet to such chamber; and gas re-circulating means connected to the filter chamber having liquid therein for exhausting therefrom a portion of the gas present in such filter chamber above the surface of the liquid therein and for re-introducing the exhausted gas under pressure into said filter chamber having liquid therein beneath the surface of the liquid.
Claim 2
Dependent Claim
153 words
Incinerator apparatus for disposing of combustible waste material, the apparatus comprising: a combustion chamber having an inlet for admitting combustion air and having an outlet; a plurality of fIlter chambers, each having a gas inlet and a gas outlet; first duct means connecting the outlet of the combustion chamber to the gas inlet of one of said filter chambers; second duct means connecting the gas outlet of said one filter chamber and the gas inlet of another filter chamber; at least one of said filter chambers including a quantity of liquid therein which covers the gas inlet to such chamber; and gas re-circulating means connected to the filter chamber having liquid therein for exhausting therefrom a portion of the gas present in such filter chamber above the surface of the liquid therein and for re-introducing the exhausted gas under pressure into said filter chamber having liquid therein beneath the surface of the liquid.
Claim 3
Dependent Claim
76 words
Incinerator apparatus as in claim 1 wherein: said gas re-circulating means includes an outlet disposed within said one filter chamber at a location which is beneath the surface of said liquid therein and which is substantially beneath the gas inlet for said one filter chamber; and a baffle plate is disposed substantially horizontally within said liquid at a level which is intermediate the gas inlet for said one filter chamber and the surface of said liquid.
Claim 4
Dependent Claim
114 words
Incinerator apparatus as in claim 1 wherein: each of said filter chambers include a quantity of liquid therein which covers the gas inlet to such chamber; each of said chambers includes a baffle plate having a plurality of apertures therethrough positioned substantially horizontally within the liquid at a level which is intermediate the gas inlet and the surface of the liquid; and said gas re-circulating means is connected to exhaust the gas present above the surface of the liquid in one of said filter chambers and for introducing the exhausted gas under pressure to each of said filter chambers having liquid therein via outlet means disposed beneath the gas inlets to such filter chambers.
Claim 5
Dependent Claim
88 words
Incinerator apparatus as in claim 2 wherein: said gas inlet for said one filter chamber includes a plurality of perforations for admitting gas therethrough into said liquid; said one filter chamber includes gas-permeable filtering means disposed above the surface of the liquid for passing gaseous combustion products therethrough and for blocking passage therethrough of particulate combustion products; and said gas re-circulating means includes a port positioned above said gas-permeable filtering means for exhausting from said filter chamber having liquid therein the gas present above said gas-permeable filtering means.
