Abstract
Pyrolysis apparatus (10) for processing shredded waste material, such as plastic and/or rubber waste, in which apparatus the material is processed continuously in a pyrolysis apparatus (10) that includes a feed device (30), a reactor (30) and an outlet portion (40) that have been equipped with conveyors, such as screw conveyors, and that can be used continuously. The screw (23) of the feed device (20) is at least partially placed in a liquid (22), which forms an air trap to prevent air from entering into the reactor. The outlet portion has a condensing collecting canopy (45) which is used to condense into liquid and recover the vapor formed in the reactor.
Claims5
Pyrolysis apparatus (10) for processing shredded plastic and/or rubber waste, the pyrolysis apparatus (10) comprising a feed device (20), a pyrolysis reactor (30), an outlet portion (40), a condensing column (48), and a gas collector (50), and being characterized in that the pyrolysis apparatus (10) is continuous and
- the feed device (20) comprises a feed bin (21), an inclined conveyor having a conveyor screw (23) that is at least partially located in a liquid (22) in the feed bin (21), the liquid (22) forming an air trap to prevent air from entering into the pyrolysis reactor (30),
- the pyrolysis reactor (30) is formed of a steel pipe (31) and comprises a conveyor screw (32) arranged inside the pipe for moving the waste;
- and heating resistors (33) arranged against the outer surface of the steel pipe for heating the reactor, and
- the outlet portion (40) comprises a conveyor provided with a casing pipe (43) and a discharge screw (42) for removing carbon formed in the process, the casing pipe (43) being open at the top and having, at an upper end, a roof structure (44) which is permeable to vapour, and above the roof structure (44) an inclined, grooved or corrugated condensing collecting canopy (45).
