A circulating pyrolysis furnace and a pyrolysis system having the same

Abstract

The invention discloses a circulation pyrolysis furnace and a pyrolysis system thereof, and relates to the technical field of pyrolysis equipment. The circulating pyrolysis furnace includes: a rotary cylinder, the rotary cylinder is arranged obliquely along its axial direction, and the feed end is higher than the discharge end; a sieve hole, the screen cylinder is fixedly connected with the discharge end of the rotary cylinder; a return pipe, the return pipe is arranged inside the rotary cylinder; a drainage pipe, the drainage pipe radially passes through the rotary cylinder The side wall of the screen drum is connected to the return pipe, which is used to drain the screened material into the return pipe, and the return pipe is used to transport the screened material to the rotary feed end of the barrel. The invention realizes the screening of pyrolysis materials, transports the charcoal that has not been pyrolyzed thoroughly from the discharge end of the rotary cylinder to the feed end through the return pipe, and circulates it multiple times, which can effectively shorten the length of the pyrolysis furnace and reduce the difficulty of manufacturing Reduce production costs and improve production efficiency.

Description

technical field [0001] The invention relates to the technical field of pyrolysis equipment, in particular to a circulation pyrolysis furnace and a pyrolysis system having the same. Background technique [0002] In the prior art, the mainstream pyrolysis equipment is the rotary kiln, because the rotary kiln can operate continuously, and has strong adaptability and high efficiency for processing materials. Temperature and residence time are two important technical indicators of pyrolysis. In order to make the material stay in the rotary kiln for a sufficient time, the usual method is to lengthen the kiln body or connect multiple rotary kilns in series. These two methods all have the drawback that manufacturing difficulty is bigger and cost is higher. Contents of the invention [0003] The object of the present invention is to provide a circulating pyrolysis furnace and a pyrolysis system having the same, so as to solve or at least alleviate at least one of the problems in t...
