Description

Polymer continuous pyrolysis system

The present invention relates to a polymer continuous thermal decomposition system, and more specifically, to dissolve the polymer compound such as waste vinyl, waste plastic, or highly pathogenic waste into a thermal decomposition device while being decomposed into low molecules through heat in a vacuum state to replace energy. A polymer continuous pyrolysis system capable of producing a raw material.

As modern life is modernized, livestock rearing in factory systems and polymer plastics that are used and discarded are increasing environmental pollution. Particularly, when a highly pathogenic livestock disease occurs, all of them are buried, and there is a serious problem of soil and water pollution and a high risk of disease recurrence.

Accordingly, recently, a method of thermally decomposing polymer compounds such as waste plastics or waste plastics or waste plastics such as highly pathogenic livestock has been disclosed.

In the conventional pyrolysis system, after the polymer compound is introduced into the pyrolysis device, the polymer compound is heated to 250°C to 480°C to activate the molecule by increasing the degree of disorder (entropy) than the internal energy (enthalpy) due to the endothermic reaction. When it is thermally decomposed, weak bonds are broken to generate new low-molecular (C3-C38) materials, and the distillation and separation process in which the gas generated during the thermal decomposition process is cooled and condensed by a plurality of extraction devices configured at the rear end of the thermal decomposition device It is implemented so that high-quality oil is separated from the gas, and the gas delivered from the extraction device is burned and exhausted to the outside by a gas combustion device configured at the rear end of the extraction device.

However, the conventional pyrolysis system has a process in which a certain amount of a polymer compound is introduced into the pyrolysis apparatus through a bogie means and thermally decomposed and then discharged outside the pyrolysis apparatus in order to secure a vacuum in the pyrolysis apparatus. There is a problem that the thermal decomposition process is not continuous because it is not continuously input to the thermal decomposition apparatus, thereby reducing the thermal decomposition efficiency.

In addition, the conventional pyrolysis system has a structure in which a plurality of heating pipes are arranged along the longitudinal direction while the heating means for providing heat to the pyrolysis apparatus penetrates the other side from one side in the width direction of the pyrolysis housing having a cylindrical structure, The heating pipe penetrates the pyrolytic housing is very complicated, and according to the structural complexity, maintenance is also inconvenient.

In addition, the conventional pyrolysis system, since the oil is separated from the gas through the extraction device is burned by the gas combustion device and exhausted to the outside, when a large amount of hydrochloric acid component contained in the gas reacts with oxygen during combustion Dioxins are generated, polluting the air environment, and there is a problem in that components such as gas combustion devices are easily corroded by hydrochloric acid components.

Thereafter, high heat is provided by the heating means 120 to the thermal decomposition pipe 115 of the thermal decomposition apparatus 100 to thermally decompose the polymer compound introduced into the thermal decomposition space.

Thereafter, the gas inside the thermal decomposition space generated during the thermal decomposition of the polymer compound is moved to the extraction device 300 to separate the extract, that is, oil, from the gas.

Subsequently, the gas from which the extract is separated and extracted is transferred to the neutralization device 400 and neutralized while the hydrochloric acid component in the gas is reacted with iron (not shown) in a state dissolved in cooling water (not shown).

Subsequently, the gas with reduced hydrochloric acid component is transferred to the gas combustion apparatus 500 and oxidized while being discharged to the outside while the aromatic element having a bad smell is removed.

Therefore, according to the present invention, by treating the wastes such as highly pathogenic livestock or polymer compounds such as waste vinyl or waste plastic within a short period of time, it prevents contagious outbreaks caused by high pathogenic livestock and extracts alternative fuels from waste plastics or waste plastics for recycling. Improve it.

In addition, it is lighter than an incinerator that incinerates waste at high temperature and pressure when manufactured in a size that can be mounted on a truck, so that the polymer compound can be processed regardless of where the polymer compound is generated.

In the above-described present invention, specific embodiments have been described, but various modifications can be carried out without departing from the scope of the present invention. Therefore, the scope of the invention should not be determined by the described embodiments, but should be defined by the equivalents of the claims and claims.
