DEVICE FOR PROCESSING CARBON-CONTAINING WASTES Russian patent published in 2024 - IPC F23G5/27 F23G5/40 F23G7/05 

FIELD: various technological processes; processing of wastes.

SUBSTANCE: invention relates to installations for thermal processing of carbon-containing wastes by steam pyrolysis. Device for processing carbon-containing wastes comprises three pyrolysis chambers arranged on shelves of the rack one above the other, and a cooling chamber is located under them. Each pyrolysis chamber comprises a housing in the form of a rectangular parallelepiped with double side walls forming a cavity for gas passage between them. In the upper part of each pyrolysis chamber branch pipes are mounted, combined into a collector connected to the inlet collector of the pyrolysis gases condenser, which is connected to pyrolysis gases condenser coil, which is connected to three-phase settler, which is connected to a unit for catalytic purification of gas emissions, with a reservoir for collecting liquid hydrocarbons and with a reservoir for collecting contaminated water. Inside each pyrolysis chamber and cooling chamber there is a conveyor containing three closed conveyor belts installed one above the other. Second closed conveyor belt is horizontally offset relative to the first and third conveyor belts. Inside the lower part of each pyrolysis chamber there is a pipe, in which nozzles are installed, which are located at equal distance from each other, one end of the pipe is plugged, and the other one is connected to a steam superheater and a steam generator. Above the first pyrolysis chamber, closer to its outlet branch pipe, a discharge branch pipe of the first sluice gate is mounted, from below into the first pyrolysis chamber, closer to the other end, a loading branch pipe of the second sluice gate is tightly installed, which connects the first pyrolysis chamber with the second pyrolysis chamber. Discharge branch pipe of the second sluice gate is installed in the second pyrolysis chamber, which is connected by the discharge pipe of the third sluice gate to the third pyrolysis chamber, wherein the design of the second pyrolysis chamber is similar to the first and third pyrolysis chambers, but is turned through 180° relative to them in horizontal plane. Third pyrolysis chamber is connected by the discharge branch pipe of the third sluice gate with the second pyrolysis chamber and the loading branch pipe of the fourth sluice gate with a cooling chamber. Inside the lower part of the cooling chamber there is a pipe with nozzles, one end of which is plugged, and the other is connected to the outlet branch pipe of the nitrogen-water heat exchanger through a nitrogen pump. In the upper part of the cooling chamber there are outlet branch pipes integrated into a collector connected to a cyclone-dust collector, lower part of which serves as a hopper for collecting volatile dust, at the bottom of the cooling chamber, closer to its other end, a loading branch pipe of the fifth sluice gate is connected, discharge branch pipe is directed into carbon residue collection hopper. Three-phase settler is made in the form of horizontally located cylinder, end parts of which are rounded.

EFFECT: recycling rubber, wood wastes and oil sludge to obtain condensed pyrolysis gases and carbon residue.
