Waste plastic heating pyrolysis oil fume recombinant capture device

Abstract

A waste plastic thermal pyrolysis oil fume heavy component capture device is provided in the exhaust pipe of the pyrolysis chamber of a thermal pyrolysis system. The heavy component capture device is equipped with at least one fume separator, including: a fume separation barrel with a fume separation space inside the barrel body, a fume outlet at the upper part of the barrel body connecting to a fume conduit leading to an oil recovery system, and a heavy component outlet at the lower part of the barrel body connecting to a heavy component discharge pipe returning to the pyrolysis chamber; an oil fume conduit inserted into the fume separation space from the upper part of the barrel body, one end communicating with the exhaust pipe, and the other end having a pipe opening near the lower part of the barrel body, and the height distance from the pipe opening to the fume outlet being greater than the diameter of the barrel body; the overall structure, in addition to improving the quality of oil recovery, also reduces or avoids wax (grease) adhesion and blockage in the pipeline of the oil recovery system, reducing maintenance costs or expenses.
