Title:
SYSTEM FOR PRODUCING PYROLYSIS OIL FROM WASTE
Document Type and Number:
WIPO Patent Application WO/2020/222423
Kind Code:
A3
Abstract:
The present invention relates to an apparatus and a process for obtaining oil by pyrolyzing waste such as biomass and waste synthetic resins in order to recycle waste. The present invention comprises: a primary pyrolysis apparatus (200); a secondary pyrolysis apparatus (400) having a higher pyrolysis temperature than the primary pyrolysis apparatus (200); an upper transfer apparatus (300) provided between the primary pyrolysis apparatus (200) and the secondary pyrolysis apparatus (400); wax separators (310, 320, 330) which are provided at the upper part of the upper transfer apparatus (300), and which separate high-boiling-point wax components from pyrolysis gas having various carbon numbers; and an oil separation apparatus (600) which is connected with the wax separators (310, 320, 330), and which condenses the pyrolysis gas so as to separate out oil, wherein the pyrolysis gas flows through the upper part of the upper transfer apparatus (300), the upper transfer apparatus (300) transfers the pyrolysis gas to the wax separators (310, 320, 330), and has a forwardly and reversely rotatable screw provided at the lower part thereof, thereby transferring solid residues to the primary pyrolysis apparatus (200) or the secondary pyrolysis apparatus (400), and the wax separators are formed so that the separated high-boiling-point wax components fall toward the upper transfer apparatus (300) through the lower end thereof.
