Description

Screw-type pyrolysis device

[0001] The present invention relates to a pyrolysis device, and more specifically, to a screw-type pyrolysis device.

[0002] In general, due to recent high population density and rapid industrialization and urbanization, various types of waste are being generated rapidly, and as a result, the disposal of combustible waste such as waste vinyl and waste plastic is emerging as a social issue.

[0003] Methods for treating such combustible waste include recycling, incineration, and landfilling. However, there are limitations on the materials that can be recycled, and in the case of incineration, there are serious secondary air pollution problems caused by the emission of air pollutants such as dust, hydrogen chloride (HCl), sulfur oxides (SOx), nitrogen oxides (NOx), and dioxins. In the case of landfilling, there are also serious pollution problems caused by soil contamination due to the non-biodegradability of combustible waste and by leachate. Accordingly, as a means of recycling combustible waste without incineration or landfilling, research and development of liquefaction methods and devices capable of obtaining useful oil by thermally decomposing combustible waste are actively underway.

[0004] Existing processes capable of producing gaseous fractions through pyrolysis include pyrolysis devices such as CSTRs (continuous stirred tank reactors), screw-type kilns, and rotary kilns.

[0006] Conventional screw-type pyrolysis devices of this type have low energy efficiency due to the heating method using a combustion fan, difficulty in switching to an internal heating furnace, and difficulty in modularization because the screw shaft must be rotatably equipped.

[0007] The present invention is proposed to solve the problems of the conventional technology described above, and aims to provide a screw-type pyrolysis device that is easy to modularize and reduces heat waste through an internal heating structure.

[0008] For the above purpose, the present invention comprises an installation casing and a plurality of transfer modules installed in the installation casing;

[0016] The above heater part is characterized by extending through the screw body and the inner side of the screw blade.

[0017] In the above, the heater portion comprises a hollow heater casing and one or more heater insertion members inserted into the heater casing;

[0018] The heater insertion member is characterized by having a heater insertion hole formed through it in the longitudinal direction, into which a heater is inserted.

[0019] In the above, the casing is provided with a plurality of hollow, longitudinally spaced chute sections, and hollow nozzle sections are provided on the longitudinally outer sides of both chute sections;

[0020] The chute portions on both sides in the longitudinal direction are extended in opposite directions in the vertical direction, and the nozzle portions are provided extending to both sides in the vertical direction;

[0021] The downwardly extended chute portion of the transfer module located at the top is coupled to the upwardly extended chute portion of the transfer module located at the bottom, and the nozzle portion of the transfer module located at the top is coupled to the nozzle portion of the transfer module located at the bottom on both sides of the outer longitudinal direction of the chute portion;

[0022] The screw body is a cylindrical hollow body located on the inner side of the nozzle part, having an annular body flange on at least the outer side in the longitudinal direction, and having one or more body part holes formed along the circumferential direction; the body part holes are characterized by being formed at a position communicating with the nozzle part.

[0025] The screw-type pyrolysis device according to the present invention is easy to install in an installation casing, as the screw part is rotatably installed in the casing with an shaftless screw blade rotation structure to transport the pyrolysis product, and is equipped with a structure in which the screw part rotates inside through a main body opening, thereby ensuring smooth gas flow through the nozzle part.

[0026] In addition, a heater section is provided with a heater installed on the inner side of the transported pyrolysis material to prevent heat waste and improve thermal efficiency, an insulating member is provided at the end to prevent heat loss, and since the rotating body has a segmented structure and is equipped with an insulating member, heat loss is prevented.
