Description
The present invention relates to the recycling of flammable waste such as rubber, waste synthetic resins, waste plastics, and more particularly, by supplying flammable waste continuously in a state in which the outside air is blocked to be completely pyrolyzed to produce high quality refined oil. The present invention relates to a pyrolysis emulsifying apparatus for continuous pyrolysis of combustible wastes, which enables the remaining gas to be used as a pyrolysis heat source.
In general, in the field of waste treatment, the liquor of the prior art is mostly incinerated with air, but recovers the heat of incineration generated as much as possible, removes the harmful substances contained in the combustion gas below the legal limit, and then removes a large amount of the combustion gas. At the same time as the discharge to the atmosphere, a series of treatments are performed to solidify the landfill by burning the residue and fly ash generated.
However, the secondary pollution due to the accumulation of harmful substances remaining in the combustion gas discharged to the atmosphere during the waste treatment process and the residual harmful substances solidified and buried, as a factor of serious environmental degradation, the development of new waste treatment technology is required. It is becoming.
In order to meet such a demand, the development of the technology which can recycle a waste in recent years is actively going on.
For example, a method of recycling polymer wastes such as waste plastics made from petroleum as a raw material of flammable wastes, which decomposes a polymer material by applying heat in an oxygen-free condition and converts it into a low-molecular material to return it to oil. Pyrolysis emulsion technology.
Existing flammable waste pyrolysis emulsifying apparatus has two methods: a batch type in which waste is charged into a pyrolysis chamber to apply heat from the outside, and a continuous type of pyrolysis while continuously injecting waste into the pyrolysis chamber.
In the pyrolysis chamber having a narrow volume, all of them heat the heat required for pyrolysis in a short time. As a result, carbon is coated on the wall of the pyrolysis chamber, resulting in rapid heat transfer and poor thermal decomposition. In addition, various problems such as the various facilities of the pyrolysis chamber did not operate smoothly due to rapid feed heating.
In addition, in the discharge of residues generated after pyrolysis, there are many problems in discharging the residues automatically and safely in a state of being blocked with external air.
For this reason, although many pyrolysis apparatuses have been developed, they are not practically used in the industrial field.
Accordingly, an object of the present invention has been devised in view of the above-mentioned point, and in order to increase the thermal decomposition efficiency of the combustible waste, the crushed combustible waste pieces are continuously supplied while maintaining an anoxic or low oxygen atmosphere state, and are continuously supplied. Combustible waste continuous to maximize the contact area with the heat source necessary for pyrolysis to achieve complete pyrolysis, and to produce high quality mixed refined oil by removing, opening and condensing the gas generated by pyrolysis to remove foreign substances in the gas. The present invention provides a pyrolysis emulsifying apparatus.

It is also an object of the present invention to provide a flammable waste continuous pyrolysis emulsification apparatus having safety and efficiency of continuous operation by automatically discharging the remaining residue after the completion of pyrolysis in a state disconnected from external air.
The combustible waste continuous pyrolysis emulsifying apparatus of the present invention for achieving the above object is a pyrolysis emulsifying apparatus for producing oil by pyrolyzing combustible waste, wherein the crushed combustible waste pieces are transported by a predetermined amount, and the waste is transported in a predetermined amount. Supplying a continuous supply device to maintain an anoxic or low oxygen atmosphere, a plurality of pyrolysis chambers for pyrolyzing the combustible waste pieces continuously under stable operation conditions, and supplying a heat source using fuel as oil and non-condensing gas to the pyrolysis chamber. Residue discharge device consisting of a pyrolysis device consisting of a combustion furnace, cooling means for cooling the high temperature residues remaining after the completion of the pyrolysis, discharge means for automatically discharging the residues via the cooling means in the state disconnected from the external air, and Reforming tower reforming pyrolysis gas, reformer And a pyrolysis gas condensation device comprising a plurality of condensers for condensing the gas to produce oil, wherein the pyrolysis device is installed outside the plurality of pyrolysis chambers to apply heat from the outside, and is installed inside the pyrolysis chamber. It is characterized in that it is provided with a heat supply tube for receiving heat from the combustion furnace to apply heat therein.

Pyrolysis emulsifying apparatus for continuous pyrolysis of combustible wastes of the present invention, regardless of the shape of the combustible wastes supplied by shredding during continuous pyrolysis of combustible wastes with a heat source required for pyrolysis in two or more stages of pyrolysis chamber having a large volume and area. Maximizes the contact area for complete pyrolysis, and makes remaining residue dry and automatically discharged by the continuous automatic discharge device, which is essential for continuous operation, and ensures stability and efficiency of continuous operation. Through the filtering device to remove the internal foreign matter and reforming in the metal catalyst reforming tower has the effect of producing a high quality refined mixed oil.
In addition, thermal decomposition can be performed regardless of the shape and density of materials such as waste synthetic resin, waste vinyl, composite waste vinyl, and waste rubber, and energy-efficient and environmentally-friendly pyrolysis using non-condensable gas as a heat source for pyrolysis facilities. By providing emulsification technology, it is possible to increase the recycling of flammable waste, which has the effect that can be put to practical use in many industrial sites in the future.
