Abstract
Abstract An incinerator for disposing of sewage that incorporates a combustor to develop high temperatures and an injection tube to deliver heat directly to the sewage. The sewage is vaporized and passes through a residence chamber. The residence chamber is raised to an elevated temperature of approximately 1600 degrees F. by gas from the combustor. This high temperature oxidizes any organic contaminates. The exterior surfaces of the device are maintained at close to ambient temperatures through the use of an induction system that brings the combustor air through a passage between the inner and outer tanks.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
136 words
A waste incinerator for converting sewage or other wastes into a non-toxic gaseous form comprising: combustion means for producing pressurized high temperature gas; tank means for containing the sewage to be treated; injector means for introducing said gas into said sewage below the initial level thereof; exhaust means for conveying said gas and vaporized sewage to the exterior of said tank means; said combustion means comprising a generally cylindrical inner core member having a plurality of air injection openings along its length; a generally cylindrical colander element surrounding said core member and having a plurality of openings distributed over substantially all of its surface excepting that portion of its surface adjacent the air inlet from a blower; and whereby combustion and cooling air is distributed substantially equally to all of said injection openings in said core.
Claim 2
Dependent Claim
136 words
A waste incinerator for converting sewage or other wastes into a non-toxic gaseous form comprising: combustion means for producing pressurized high temperature gas; tank means for containing the sewage to be treated; injector means for introducing said gas into said sewage below the initial level thereof; exhaust means for conveying said gas and vaporized sewage to the exterior of said tank means; said combustion means comprising a generally cylindrical inner core member having a plurality of air injection openings along its length; a generally cylindrical colander element surrounding said core member and having a plurality of openings distributed over substantially all of its surface excepting that portion of its surface adjacent the air inlet from a blower; and whereby combustion and cooling air is distributed substantially equally to all of said injection openings in said core.
Claim 3
Dependent Claim
42 words
The incinerator of claim 1 wherein: said injector means comprising: a generally vertical pipe member having a discharge end spaced from the bottom of said tank means; and a concentric tube member surrounding said vertical pipe member at the lower portion thereof.
Claim 4
Dependent Claim
23 words
The incinerator of claim 2 wherein: a deflector means for creating a swirling action in said sewage is mounted coaxially with said pipe.
Claim 5
Dependent Claim
23 words
The incinerator of claim 3 wherein: said deflector means comprises a diverter cone mounted adjacent the lower end of said vertical pipe member.
Claim 6
Dependent Claim
39 words
The incinerator of claim 2 further including: plate deflector means surrounding said vertical pipe member and secured vertically above said concentric tube mEmber for deflecting sewage raised by said gas toward the sides and bottom of said tank means.
Claim 7
Dependent Claim
95 words
A waste incinerator for converting sewage or other wastes into non-toxic gaseous form comprising: combustion means for producing pressurized, high temperature gas; tank means for containing the sewage to be treated; injector means for introducing said gas into said sewage below the initial level thereof; exhaust means for conveying said gas and vaporized sewage to the exterior of said tank means; residence means for raising the temperature of said gas and said vaporized sewage to oxidize and deodorize said organic contaminates; said residence means is heated by gas from a tap on said injector means.
Claim 8
Dependent Claim
95 words
A waste incinerator for converting sewage or other wastes into non-toxic gaseous form comprising: combustion means for producing pressurized, high temperature gas; tank means for containing the sewage to be treated; injector means for introducing said gas into said sewage below the initial level thereof; exhaust means for conveying said gas and vaporized sewage to the exterior of said tank means; residence means for raising the temperature of said gas and said vaporized sewage to oxidize and deodorize said organic contaminates; said residence means is heated by gas from a tap on said injector means.
Claim 9
Dependent Claim
57 words
A waste incinerator according to claim 6 further including: tank cooling means for cooling the exterior of said tank means; said cooling means comprising an annulus between the inner portion of said tank means and the exterior of said tank means; whereby the combustion air for said combustion means travels through said annulus to cool said tank.
Claim 10
Dependent Claim
32 words
The incinerator of claim 6 wherein: said residence means comprises a labyrinth chamber means for causing said gas to undergo at least two reversals in direction before being exhausted to the atmosphere.
