Pyrolysis apparatus for processing shredded waste material, such as plastic and/or rubber waste, which pyrolysis apparatus includes a feed device, a pyrolysis reactor, an outlet portion and a gas collector for collecting the gas from the pyrolysis reactor, whereby the pyrolysis apparatus is continuous and characterised in that - the feed device includes - a bin into which the feed material is poured and which bin contains a liquid high enough to form an air trap to prevent air from entering into the reactor; - a screw conveyor screw which is inclined and located in conjunction with the bin and at least partially placed in said liquid, transferring the feed material from the bin to the reactor; - a gutter or gutter-like space at the bottom of the screw conveyor along which the liquid transported with the material and/or in the screw can flow back into the bin and; - said screw being equipped with a work-pause timer and having threads which do not go all the way to the end; - the pyrolysis reactor - is formed by a thermally insulated steel pipe, which forms the reactor chamber, inside which, is a screw conveyor, the steel pipe having heat resistors located around the steel pipe and tightened against its outer surface; - has the resistor output being controlled by for example a PID controlled control device, such as thyristor control or a semiconductor relay; - has the sensors of the control device being located in sealed pipes that are fastened in the interstices between the resistors and that are connected to the reactor chamber; - outlet portion has a conveyor, such as a discharge screw, and a condensing collecting canopy which is used to condense into liquid and recover the vapour conveyed in connection with the removal of carbon. - the feed device includes - a bin into which the feed material is poured and which bin contains a liquid high enough to form an air trap to prevent air from entering into the reactor; - a screw conveyor screw which is inclined and located in conjunction with the bin and at least partially placed in said liquid, transferring the feed material from the bin to the reactor; - a gutter or gutter-like space at the bottom of the screw conveyor along which the liquid transported with the material and/or in the screw can flow back into the bin and; - said screw being equipped with a work-pause timer and having threads which do not go all the way to the end; - a bin into which the feed material is poured and which bin contains a liquid high enough to form an air trap to prevent air from entering into the reactor; - a screw conveyor screw which is inclined and located in conjunction with the bin and at least partially placed in said liquid, transferring the feed material from the bin to the reactor; - a gutter or gutter-like space at the bottom of the screw conveyor along which the liquid transported with the material and/or in the screw can flow back into the bin and; - said screw being equipped with a work-pause timer and having threads which do not go all the way to the end; - the pyrolysis reactor - is formed by a thermally insulated steel pipe, which forms the reactor chamber, inside which, is a screw conveyor, the steel pipe having heat resistors located around the steel pipe and tightened against its outer surface; - has the resistor output being controlled by for example a PID controlled control device, such as thyristor control or a semiconductor relay; - has the sensors of the control device being located in sealed pipes that are fastened in the interstices between the resistors and that are connected to the reactor chamber; - is formed by a thermally insulated steel pipe, which forms the reactor chamber, inside which, is a screw conveyor, the steel pipe having heat resistors located around the steel pipe and tightened against its outer surface; - has the resistor output being controlled by for example a PID controlled control device, such as thyristor control or a semiconductor relay; - has the sensors of the control device being located in sealed pipes that are fastened in the interstices between the resistors and that are connected to the reactor chamber; - outlet portion has a conveyor, such as a discharge screw, and a condensing collecting canopy which is used to condense into liquid and recover the vapour conveyed in connection with the removal of carbon.
