Description

Fitness type pyrolysis oil recovery apparatus using waste material}

The present invention relates to a regeneration device for obtaining pyrolysis oil using waste materials. Specifically, the thermal expansion adaptation is formed to prevent breakage due to cracking and deformation while the regeneration chamber and regeneration furnace are thermally expanded by combustion heat for pyrolysis. It relates to a type waste material pyrolysis oil regeneration device.

In general, with the rapid development of the industry and the increasing demand, large quantities of waste materials are emitted, which is a very serious social problem as a major cause of pollution and destruction of the environment and ecosystem.

Therefore, the government or each organization relies heavily on the collection and incineration or landfill of waste (waste materials) as a solution to the above problems. However, in the case of incineration, a large amount of harmful substances such as dioxins are discharged into the atmosphere, causing further pollution, and in the case of landfill, of course, the ground does not decay due to the nature of the plastic that does not rot. Conflict between regions due to lack of public relations has emerged as a major issue.

Accordingly, in order to solve this problem, the present applicant provides a waste material pyrolysis oil regeneration device capable of recovering pyrolysis oil through pyrolysis of waste material and at the same time realizing the complete incineration of the waste material, thereby recycling resources and preserving the environment. It is getting a lot of attention from the side.

The brief background on the waste material pyrolysis is described as follows.

The collected waste raw material is introduced into a sealed regeneration furnace, and thermally decomposed the input waste material by applying high temperature heat from outside of the regeneration furnace under an oxygen-free or low oxygen atmosphere. At this time, the polymer compound having a long carbon chain is thermally decomposed in the absence of oxygen to low molecular weight into various organic compounds. The low molecular weight product becomes a gas or a liquid depending on the length of the carbon chain or the form of the compound. In other words, this material is a technology that maintains almost the same properties as petroleum-based compounds to enable reuse as a fuel for combustion.

That is, the waste raw material is a polymer chemical containing an organic chemical having a carbon chain. Firstly, although it is different from the conditions and degree, it is easily decomposed by applying heat. Second, even if toxic substances are generated, it is generated in pure form or air. The ratio is very low and relatively easy to process. Third, expensive raw materials such as monomers can be recovered by reducing the polymer waste raw material to the original low molecular weight material, and the combustion gas or oil can be recovered. It is possible to pyrolyze waste materials.

Such waste raw material pyrolysis oil regeneration apparatus is a regeneration chamber in which combustion heat is introduced from both combustion heat inlets and discharged to a combustion heat outlet at a later stage, and a regeneration of waste raw materials installed and installed in the regeneration chamber is pyrolyzed. Pyrolysis gas discharge pipe formed along, waste material supply means for supplying the waste material into the regeneration furnace, the debris discharge means for discharging the debris installed in front of the regeneration furnace and the pyrolysis gas discharge pipe is introduced And a condenser for condensing the pyrolysis gas into the liquid state.

In order to operate the waste raw material pyrolysis oil regeneration device, since a high temperature combustion heat is supplied into the regeneration chamber to heat the regeneration furnace, a large temperature difference occurs when compared with before operation. Accordingly, it can be seen that the regeneration chamber and the regeneration furnace in operation due to such a temperature difference generate a large length deformation due to thermal expansion in the longitudinal direction before and after the operation.

However, since the conventional regeneration chamber is not only fixed by an external structure but also conventional regeneration furnace and fixed installation inside the regeneration chamber, the heat of the regeneration chamber and the regeneration furnace is repeated when the operation and stop of the waste material pyrolysis oil regeneration device are repeated. As expansion and contraction are repeated, breakage due to cracking and deformation frequently occurs. Moreover, when operating waste material pyrolysis oil regeneration apparatus, not only the noise occurs in each element such as the bolt coupling part or the welding part due to the initial thermal expansion, and in severe cases, the bolt coupling part or the welding part is broken, which leads to a very dangerous situation.

In addition, the regeneration chamber is usually composed of a double and filled with a heat insulating material to prevent heat loss therebetween, as described above, if the thermal expansion and contraction is repeated in the longitudinal direction before and after the crack occurs in the heat insulating material and the gap is gradually opened. There is a problem that a lot of heat loss occurs because of losing.

In addition, in the conventional regeneration furnace, a combustion heat circulation tube for circulating combustion heat, a rotor installed at an upper portion of the combustion heat circulation tube, and a rotor for dispersing waste material introduced through a pyrolysis gas discharge port, and debris installed and pyrolyzed under the combustion heat circulation tube. It also constitutes a screw for guiding the debris to the debris discharge means, even in this case, the combustion heat circulation tube, the rotor and the screw is thermally expanded to a different size than the regeneration furnace, causing a problem of cracking, breakage or deformation.
