FIELD: technological processes.
SUBSTANCE: invention relates to destructive distillation of carbon-containing materials in reactors with screw conveyors. Continuous reactor comprises pyrolysis chamber 1, combustion chamber 2, multi-screw conveyor, burners for combustion of liquid and / or gaseous fuel 7 and supercharger to feed air 8 into combustion chamber 2, which covers the entire pyrolysis chamber 1, and pyrolysis chamber 1 in its lower part comprises open channel 9 for movement of material by multi-screw conveyor, wherein pyrolysis chamber 1 and combustion chamber 2 are made in form of regular quadrangular prisms, upper bases of which are connected to exhaust domes 10, 11, exhaust cupola 11 of combustion chamber 2 envelopes exhaust cupola 10 of pyrolysis chamber 1 with formation between them of annular channel 13 of flue gases, open channel 9 of the multi-screw conveyor is made in the form of a row of trays 14 filling the prismatic volume of pyrolysis chamber 1, each tray 14 of row is formed by vertical walls and connecting them with semi-cylindrical shell, semicylindrical shells of trays 14 form wavy bottom of pyrolysis chamber 1, for transfer of material from tray to tray end section of each tray is connected to initial section of next tray window, kinematic chain of multi-screw conveyor and direction of screw coils are made with possibility of multiple movement of raw material through pyrolysis chamber 1 in two opposite directions, successively along all channel trays. Reactor can be equipped with cylindrical supercharge chamber 22, which is located under combustion chamber 2, separated from it by grate 23 and comprises tangential air supply 24, which is connected with supercharger 8. Continuous action reactor for pyrolysis of carbon-containing materials is characterized by lower than in analogues, material consumption, labor intensity, production and operational costs.
EFFECT: reactor is characterized by mobility, higher efficiency and is adapted for operation on solid fuel.
