Cyclone incinerator

Claim 2

A cyclone incinerator for solid waste comprising a vertically oriented cyclone separator having a closed upper end and an open lower end, a tangential inlet duct adjacent the upper end for admitting pneumatically propelled miscellaneous solid waste, and a centrally located exhaust duct extending vertically through said separator and out the upper end, inclined kiln means substantially enclosing the lower end of said cyclone separator for supporting combustible components of the solid waste for further burning and for separating noncombustible and other components to drop by gravity into a residue chamber, and a recirculation line connected between said residue chamber and inlet duct for recirculating unburned combustible particulates.

Claim 3

A cyclone incinerator according to claim 1 wherein said inclined kiln means is comprised by a conical kiln collector plate having a central exit opening.

Claim 4

A cyclone incinerator according to claim 2 further including a flow deflector structure carried by said kiln collector plate for weakening the flow in the vicinity of the entrance to said exhaust duct and reducing undesired particulate emission.

Claim 5

A cyclone incinerator according to claim 1 wherein said inclined kiln means is comprised by a rotatable conical kiln collector plate having a central exit opening.

Claim 6

A cyclone incinerator according to claim 1 further including a coarse screening adjacent to the wall of said cyclone separator to augment separation and burning of small particulates.

Claim 7

A cyclone incinerator according to claim 1 wherein said exhaust duct has wound piping for circulating fluid for recovery of heat.

Claim 8

A cyclone incinerator according to claim 1 wherein said recirculation line is connected to said inlet duct sufficiently upstream to obtain pre-drying of the admitted solid waste.

Claim 9

A cyclone incinerator for solid waste comprising a vertically oriented cyclone separator including at least an inverted truncated conical chamber having a closed upper end and an open lower end, a tangential inlet duct adjacent the upper end for admitting pneumatically propelled miscellaneous solid waste, and an exhaust duct extending axially through said separator and out the upper end, kiln means substantially enclosing the lower end of said cyclone separator and including a rotatable, inverted conical collector plate for supporting combustible components of the solid waste for further burning and for separating non-combustible and other components by gravity to drop through a central exit opening into a residue chaMber, a flow deflector structure attached to said conical collector plate for weakening the flow in the vicinity of the entrance to said exhaust duct and reducing particulate emission, and a recirculation line connected between said residue chamber and inlet duct for recirculating unburned combustible particulates.

Claim 10

A cyclone incinerator for solid waste comprising a vertically oriented cyclone separator including at least an inverted truncated conical chamber having a closed upper end and an open lower end, a tangential inlet duct adjacent the upper end for admitting pneumatically propelled miscellaneous solid waste, and an exhaust duct extending axially through said separator and out the upper end, kiln means substantially enclosing the lower end of said cyclone separator and including a rotatable, inverted conical collector plate for supporting combustible components of the solid waste for further burning and for separating non-combustible and other components by gravity to drop through a central exit opening into a residue chaMber, a flow deflector structure attached to said conical collector plate for weakening the flow in the vicinity of the entrance to said exhaust duct and reducing particulate emission, and a recirculation line connected between said residue chamber and inlet duct for recirculating unburned combustible particulates.

Claim 11

A cyclone incinerator according to claim 8 further including a coarse screening adjacent to the wall of said cyclone separator near the lower end thereof for augmenting separation and burning of small particulates.

Claim 12

A cyclone incinerator according to claim 8 wherein said exhaust duct has wound piping for circulating water for recovery of heat.

Claim 13

A cyclone incinerator according to claim 8 wherein said recirculation line is connected to said inlet duct sufficiently upstream to obtain pre-drying of the admitted solid waste.
