In the following description, components having the same reference numerals in different drawings have similar functions, so that they will not be described repeatedly unless necessary for an understanding of the invention, and the known components will be briefly described or omitted. However, It should not be understood as being excluded from the embodiment of Fig.

FIG. 1 illustrates a regenerative resource production apparatus applied to a new and renewable energy generation apparatus by treating a polymer waste according to an embodiment of the present invention.

1, the recycled resource production apparatus 10 includes a heat treatment apparatus 11; A separation device (12) for separating the liquid sludge from the waste treated in the heat treatment apparatus (11); A cooling device (13) for cooling the waste treated in the separation device (12) to make the water and the vapor in a liquid state; A water precipitation tank (14) for separating the syngas from the waste treated in the cooling device (13); A water separation device 15 for separating water and heavy oil from the liquid processed material transferred from the oil precipitation tank 14; A mixing device (16) connected to the oil water separator (14) for mixing and stirring the heavy oil transferred from the liquid processed product with water to emulsify the oil; And a storage tank (17) connected to the mixing device (15) for storing the emulsified water and the middle stream, wherein the separated syngas is transferred to the heat treatment device (11) The device 16 consists of a stirring device for mixing water, heavy oil and additives and a homogeneous device for homogenizing the mixture transferred to the stirring device.

As used herein, recycled resources means synthetic gas, heavy oil or solids produced by the treatment of polymer wastes, or treated to be used as fuel by applying appropriate physical or chemical changes thereto. The fuel may be used for the operation of the boiler or the operation of the turbine or may be stored in a storage tank through an appropriate treatment process. Physical or chemical changes refer to, for example, separating the synthesis gas into various types of gas or adding other combustion aids. Or adding water or an additive to the heavy oil to make it into an emulsion state. On the other hand, the polymer waste may include wastes made of any polymeric material capable of producing regenerated fuels including, but not limited to, waste plastics, waste vinyl, waste nets, or waste tires.

According to the present invention, in order to generate new and renewable energy, regenerated fuel must first be produced from the polymer waste.

Renewable fuels can be generated in the processing of polymer waste. Polymer waste collected in various collection points can be put into the melting furnace 111. The melting furnace 111 can be installed so as to be rotatable in a cylindrical shape. At least one screw may be installed inside the melting furnace 111, and the screw may prevent the polymer waste, which is melted at the same time, from being attached to the wall while transferring the charged waste.

The heat treatment apparatus 11 for heat treatment of the polymer waste may include a melting furnace 111 for melting and pyrolyzing the waste and a heating furnace 112 for supplying heat to the melting furnace 111.

A heating furnace 112 may be installed to heat the melting furnace 111. The heating furnace 112 may be, for example, a gas burner and may be a composite gas burner. The use of the composite gas burner is intended to use a common gas for the initial operation of the heating furnace 112 and to use the syngas generated as the treatment of the polymer waste proceeds as a combustion raw material for the heating furnace 112. The heating furnace 112 can be constructed in a structure in which a burner is installed along the front and longitudinal direction of the melting furnace 111. In the heating furnace 112, the burner can be installed below the cylindrical cylinder and can be heated along the peripheral surface by the rotation of the melting furnace 111, and by the plurality of burners installed along the longitudinal direction, The entire surface of the substrate 111 can be heated. The heating furnace 112 can heat the melting furnace 111 to a temperature of, for example, 300 to 700 占 폚, but the heating temperature can be appropriately adjusted depending on the temperature of the polymer waste. The electric dust collector 114 may be installed if necessary but is not necessarily required. And the supply of gas to the heating furnace 112 can be done through the external gas inlet 113 or through the syngas inlet.

The syngas and the vapor generated from the waste melted in the melting furnace 111 can be transferred to the separating device 12. In the separation device 12, the liquid sludge is again transferred to the melting furnace 111, and the vapor and water vapor in the gaseous state can be transferred to the cooling device 13. The vapor and vapor in the gaseous state in the cooling device 13 are cooled and changed to the liquid state, so that the vapor becomes the regeneration flow path in the liquid state. Thus, in the melting furnace 111, the syngas, the vapor and the liquid such as water can all be in a gaseous state and can be transferred to the liquefying sludge and the separator 12. And the liquefied sludge can be transferred from the separator 12 back to the melting furnace 111. [ On the other hand, the water vapor and the vapor component can be converted from the gas form to the liquid form in the cooling device 13. Thus, the cooling device 13 changes the water and vapor components into liquid. The cooling device 13 may be, but not limited to, for example, air cooling, water cooling, natural cooling, or a mixture thereof. For example, a cooling unit (not shown) in which the temperature is suddenly lowered may be installed at the end of the cooling device 13. The cooling unit may be, for example, in the form of a plurality of tubes and may be a reduced pressure cooling tube. The use of a reduced pressure cooling tube is intended to prevent some of the water vapor or vapor from becoming liquefied. However, since the syngas must be maintained in the gaseous state, the cooling temperature of the cooling unit can be set to at least a higher temperature than the vaporization temperature of the synthesis gas.

The polymer waste treated in the cooling device 13 can be liquid water, vapor and solids, and can contain syngas. The syngas component can be separated from the oil precipitation tank 14 and transferred to the melting furnace 111 to be used as fuel or transferred to the storage tank 17. The oil precipitation tank 14 may be, for example, an apparatus for allowing a syngas component to be discharged by pressure as external pressure is applied, and to allow solids to settle in liquid form water and regeneration oil. The syngas separated from the oil precipitation tank 14 can be transferred to the melting furnace 111 and used as a raw material or transferred to the storage tank 17, as described above.

The water and regeneration liquid of the liquid component processed in the oil precipitation tank 14 can be transferred to the oil water separator 15. If necessary, the solid matter may be treated separately before being conveyed to the oil water separating device 15. [

The oil water separator 15 is for separating heavy oil and water, and heavy oil and water can be separated into two layers. The oil-water separator 15 may be, for example, a cylindrical vessel having an outlet formed in the lower portion thereof, and may be made so that heavy oil and water can form a layer. The temperature of the oil water separator 15 can be adjusted as needed. For example, the temperature of the oil water separator 15 may be maintained at 5 to 15 占 폚. The oil water separator 15 may be connected to the wastewater tank 15a and a filter may be installed in the wastewater tank 15a. On the other hand, the water-oil separator 15 may be connected to the mixing device 16. When the water and the heavy oil are completely separated from each other in the oil water separator 15, the water is transferred to the wastewater tank 15a and the heavy oil can be transferred to the mixing device 16. The remaining solids can be transferred separately after drying. The water transferred to the wastewater tank 15a can be transferred to the mixing device 16 after filtration.

The weight ratio of the heavy oil to the water, which is mixed and fed to the mixing device 16, can be from heavy oil: water = 85: 25 to 10. The mixing device 16 can have a stirrer and can be mixed and emulsified by stirring additives, such as, for example, calcium chloride, water and heavy oil. The regeneration oil that has been put into the emulsion state can then be transferred to the storage tank 17.

The storage tank 17 may be composed of at least two storage rooms 171, 172 and 173. A regeneration oil reservoir 171 in the emulsion state, a syngas reservoir 172, or a solids reservoir 173. The regenerated oil in the emulsion state generated in the mixing apparatus 16 is stored in the regenerating oil reservoir 171 and transferred to the heat treatment apparatus 11 in the syngas reservoir 172 and the remaining syngas is stored and stored in the solids reservoir 173, The solids treated in the oil-water sedimentation tank 14 or the oil-water separation device 15 can be stored. Each of the reservoirs 171, 172, 173 may have a requirement for storage in its respective storage and the present invention is not limited by the specific design details of the reservoirs 171, 172, 173.
