PYROLYTIC ENERGY RECOVERY SYSTEM Russian patent published in 2013 - IPC C10B53/00 C10G1/00 C10G9/00 B09B3/00 

FIELD: chemistry.

SUBSTANCE: disclosed is a pyrolytic energy recovery system for pyrolysis of wastes to obtain pyrolysis oil. The pyrolytic energy recovery system for pyrolysis of wastes to obtain oil comprises: a recovery furnace formed from multiple walls on the front, the back, sides, the ceiling and floor including insulating layers; a heat plate for dividing the inner space of the recovery furnace into upper and lower parts and having a height lowered from a centre part to both sides thereof and formed with at least one ridge and valley in a longitudinal direction thereof; a heating chamber disposed under the heat plate and heated by a burner installed aside the recovery furnace; a pyrolysis chamber disposed over the heat plate and pyrolysing the wastes fed through a recyclable material inlet port installed in the upper part of the front or rear surface of the recovery furnace using a large amount of transferred circulating heat; a heating pipeline installed inside between the front and rear surfaces of the recovery furnace in a maze shape such that the heat coming from the heating chamber flows from a lower side to an upper side along inner surfaces of front and rear walls of the recovery furnace in a zigzag manner, and then, returns into the heating chamber at a pressure lower than a predetermined pressure and is discharged to the exterior at a pressure higher than the predetermined pressure; rotary means consisting of a plurality of rotating components installed in the pyrolysis chamber under the recyclable material inlet port in a longitudinal direction to evenly distribute recyclable materials fed through the recyclable material inlet port; residue discharge means having primary residue conveyance screws longitudinally installed along the valley of the heat plate and rotated to convey the residue toward the centre part from both sides, a residue hopper installed in a separate space in the heating chamber such that the residue conveyed to the centre part of the heat plate through the primary conveyance screws is lowered to be gathered, and a secondary residue conveyance screw installed from the residue hopper to the exterior of the recovery furnace and discharging the residue accumulated in the residue hopper to the exterior of the recovery furnace; and condensing means separately installed at the exterior of the recovery furnace and receiving vaporised extracts generated through pyrolysis of the recyclable material in the pyrolysis chamber to exchange heat with the extracts to extract liquefied recovery oil.

EFFECT: reduced heat loss, more efficient heat transfer in the pyrolysis region.
