Title: Electro-smokeless extraction/recovery system
IPC: F27D99/00
Filed: 2000-10-03
Abstract: 1. An electro-smokeless extraction/recovery system with zero air emissions for converting waste and shredded scrap tires to carbon black and steel and fluid discharge of oil, fuel, and chemical gases comprising, in combination: a reaction vessel formed with a generally cylindrical side wall and a bottom plate having a plurality of heat apertures and a plurality of drain apertures therethrough, the vessel also having an open top for the receipt of waste and shredded scrap tires with a lid adapted to be removably placed over the top with sealing bolts for sealing purposes to allow for pressurized heating in the absence of air; a plurality of hollow sheaths formed of a thermally conductive material each sheath having spaced concentrical cylindrical side walls and a closed top and an open bottom positioned in sealing relationship with the heat aperture and extending upwardly therefrom; a plurality of electrical heating elements within each sheath positioned through the open bottom of the sheath to heat the shredded tires within the vessel, the heating element being in a spiral configuration and adapted to operate at between about 93.3 to 1648.9 degree C at between about 0.7x10<4> Pa to 13.8x10<4> Pa for between about 15 and 60 minutes, preferably 40 minutes, the sheaths containing the heating elements being between about 0.05 to 0.61m apart; a plurality of hollow drains, each having spaced concentric cylindrical side walls and a top with an open bottom positioned in sealing relationship with drain apertures, each drain also having vertically extending openings on at least a portion of the side walls thereof and extending upwardly from the bottom plate to a location adjacent with spaced baffles within each drain to the top to effect the flow of fluid discharge from the reaction vessel; and support means for the reaction vessel with a pivot pin for adjusting the angular orientation of the reaction vessel. 2. An electro-smokeless extraction/recovery system for converting waste and shredded scrap tires to carbon black and fluid discharge of oil, gas, and solvent chemicals comprising: a reaction vessel formed with a side wall and a bottom plate having a plurality of heat apertures and a plurality of drain apertures therethrough, the vessel also having an open top for the receipt of waste and shredded scrap tires with a lid adapted to be removably placed over the top; a plurality of electrical heating elements positioned through the bottom of the reaction vessel to heat the waste and shredded scrap tires within the vessel; and a plurality of hollow drain members, each having a side wall and a top with an open bottom positioned in sealing relationship with drain apertures, each drain member also having vertically extending openings on at least a portion of a side wall thereof and extending upwardly from the bottom plate to a location adjacent to the top to effect the flow of fluid discharge from the reaction vessel. 3. The system as set forth in Claim 2 and further including a plurality sheaths enclosing the heating elements. 4. The system as set forth in Claim 3 wherein the sheath members are concentric hollow cylinders with a plurality of spaced heating elements in each sheath. 5. The system as set forth in Claim 4 wherein the heating elements are arranged in a spiral configuration. 6. The system as set forth in Claim 2 wherein the drain members are concentric hollow cylinders. 7. The system as set forth in Claim 6 and further including a plurality of spaced baffles within in each drain member. 8. The system as set forth in Claim 2 wherein the heating elements are spaced at between about 0.05 to 0.61m from each other and drain members are essentially cylindrical. 9. The system as set forth in Claim 2 wherein the heating elements are essentially cylindrical and the drain members are screens configured to hold the waste and shredded scrap tires in an essentially cylindrical configuration around the heating elements. 10. The system as set forth in Claim 2 wherein the heating elements are cylindrical with generally rectilinear sheaths receiving the heating elements. 11. The system as set forth in Claim 10 wherein the drain members are rectilinear and equally spaced between the sheaths. 12. The system as set forth in Claim 2 wherein the heating elements and drain members are in a triangular configuration. 13. The system as set forth in Claim 2 wherein the reaction vessel is cylindrical. 14. The system as set forth in Claim 2 wherein the reaction vessel is rectilinear. 15. The system as set forth in Claim 2 wherein the reaction vessel is triangular.
