Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carbonization process for a white body, which is a driving part of a scrap car, from which an engine, tires, glasses and other driving parts are removed. And a method of producing a raw material for recycling. 2. Description of the Related Art It is well known that environmental issues have been taken up as social issues and are being recognized as important issues. Programs for improving the environment on a global scale have already been implemented, and laws and regulations have been implemented. Are also being gradually maintained. In particular, the development of industrial technology incorporating the concept of recycling is remarkable. For example, in the field of the automobile industry, parts that have been discarded up to now have to be repaired and used again, returned to raw materials and reused, or synthetic resins have been recycled as fuel oil and used as heat sources. is there. [0003] When synthetic resins are used as fuel oil, they are recovered by the dry distillation method. Generally, dry distillation is widely known as an external heating method, and is often used to carbonize raw materials. The equipment consists of a carbonization furnace, an oil separation tank, and a combustible exhaust gas recovery device, and is used for effective use of resources. [0004] Since these devices are of the external heat type, it is characterized in that harmful gases generated during heating are hardly discharged as long as they are completely burned. The carbonization gas discharged from the carbonization furnace contains various types of gases. Under a constant pressure, a substance having a lower boiling point is more likely to be gasified and is liable to be liquefied at a lower temperature. Volatile gases that are gaseous at normal temperature, especially methane gas and ethane gas having small molecular weight, are used as fuel gas. Conventionally, when recycling an automobile, a frame-shaped body called a white body is compressed by a large press, and then the crushed and small crushed metal is put into a furnace, melted, and the metal is recovered and used. However, it is extremely difficult to remove the adhered paint due to the high adhesion strength of the paint applied to the body, so it is necessary to put it in a metal melting furnace as it is at present. Harmful gases containing dioxins and the like are generated from paints of the type, and this is a major environmental problem. [0006] From the above points, the present invention provides
When recycling a white body, which is a frame-shaped body of a waste vehicle, once again as a raw material, the generation of harmful gas is prevented by the dry distillation method, and a raw material for recycling is manufactured, and the gas from combustion is reused. It is an object of the present invention to provide a method for producing a raw material for recycling an automobile body for disposal, which enables the above. [0007] In order to solve the above-mentioned problems, a method for producing a material for recycling an automobile body for disposal according to the first aspect of the present invention is a bellows-shaped upper and lower side of a white body.
Pressed and the pressed white body
In the direction of the bellows expansion and contraction,
The lump mass was put into a carbonization furnace equipped with a heating furnace and a flue, and after closing the lid of the carbonization furnace, the carbonization furnace was heated, air was cut off and carbonization was performed, and metals and non-metals were removed. While obtaining an inorganic substance and a carbide obtained by carbonizing an organic substance, the oil exhausted from the flue is recovered through an oil separation device that separates oil and volatile gas, and the recovered oil is made up of water and an emulsifier. It is characterized by being returned to the heating furnace as the added water-oil mixed oil and reused, and the volatile gas is washed and then returned to the heating furnace and reused. According to the present invention having such a configuration,
The white body is pressed in bellows up and down,
The pressed white body is compressed in the bellows
Into a mass that has been compressed
It is put into the carbonization furnace. After the lid of the carbonization furnace is closed, the carbonization furnace is heated by the heating furnace, the air is cut off, and the mass of the white body put into the carbonization furnace is carbonized. As a result, a carbide obtained by carbonizing a metal, an inorganic substance other than the metal, and an organic substance is obtained. Carbides and others can be easily separated by adjusting the size of the sieve, and iron can also be separated by a magnet. This has made it possible to reuse metals as raw materials for recycling. [0009] The present invention having such a structure,
During carbonization, the volatile gas is reused as a natural material, and the non-volatile gas is cooled to oil, and used as a natural material in which water and an emulsifier are mixed and as a heat source other than the carbonization device.
Also, when the white body is pressed in bellows up and down
In both cases, the left and right sides and the top and bottom are compressed to form small lumps.
Being shaped, multiple pressed white bodies
When carbonizing carbon, there is an appropriate gap between each other,
It promotes carbonization gas diffusion and increases carbonization efficiency. And e
Carbonization by reducing the volume ratio of the white body
The size should be easy to enter the furnace, and
Into a dry distillation furnace without going through the grinding process
Can be. [0010] In the production method of claim 1 , the water-oil mixed oil has a mixing ratio of water to oil of 20: 8 by adding an emulsifier.
It can be used from 0 to 65:35 . by this,
Emulsion of mixed oil and water by emulsifier
When combusted as a converted mixed oil, nitrogen oxides and sulfur
Yellow oxide generation and carbon dioxide extremely low
be able to. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic view showing an embodiment of the manufacturing method of the present invention, and FIG. 2 is a partial view of the same. In the figure, A is a white body lump, and the white body lump A is a white body, which is a vehicle body excluding a car engine, tires, glasses, and other driving parts. Is pressed in a bellows shape by a bellows-type press that operates on the upper and lower Y axes, and is compressed and reduced in volume by a biaxial press that operates on the left and right X axes and the upper and lower Y axes. Then, the mass A of the white body is put into the inner pot 2 of the dry distillation furnace 1. Reference numeral 3 denotes an opening / closing lid of the carbonization furnace 1. Reference numeral 4 denotes a heating furnace for heating the carbonization furnace 1, and the bottom of the carbonization furnace 1 is fitted to the upper part. The heating furnace 4 is made of castable refractory material, and has a heating burner 5 at the bottom. Reference numeral 6 denotes a stored water tank provided between the dry distillation furnace 1 and the oil separation tank 7. The stored water 8 enters the stored water tank 6 and includes an air space 9. The end of a dry distillation gas introduction pipe 10 which is a flue through which the dry distillation gas discharged from the dry distillation furnace 1 provided on the side of the dry distillation furnace 1 flows into the stored water 8 is introduced. The dry distillation gas introduction pipe 10 is submerged in the storage water 8 in a horizontal state, and its mouth end is closed. A plurality of discharge holes 11 are formed in the submerged portion of the dry distillation gas introduction pipe 10. Reference numeral 12 denotes a cooling unit provided on the upper part of the storage water tank 5, and the cooling unit 12 is provided outside the air layer 9.
A cooling water circulating tank 13 covering the cooling water is provided. Cooling water flows in from a cooling water inlet 14 of the cooling water circulating tank 13, flows out of a cooling water outlet 15, and is constantly circulating. Reference numeral 16 denotes a check opening / closing unit provided at the upper part of the storage water tank 6, and a dry distillation gas outlet 17 of the storage water tank 6 and a dry distillation gas introduction pipe 18 of the oil separation tank 7 are connected. 19 is a safety valve provided on the upper part of the oil separation tank 7. The non-volatile gas cooled in the oil separation tank 7 becomes oily, accumulates in the oil separation tank 7, and mixes oil and water through an oil / water separation tank 21 communicating with the oil separation tank 7 by a pipe 20. The emulsion device 22 burns the water-oil mixed oil in the heating burner 5. The oil used in the heating burner 5 is a water-oil mixed oil obtained by adding an emulsifier to a mixture of flammable oil water generated by dry distillation and the oil having a ratio of 20:80 to 65:35. On the other hand, the volatile gas which does not become oily in the oil separation tank 7 is introduced into the gas cleaning tank 24 through the gas conduit 23, and is stored in the gas cleaning tank 24 in the gas cleaning tank 24.
Then, the gas is washed through the gas conduit 26 and burned by the heating gas burner 28 of the heating furnace 4 through the gas separator 27 provided in the gas conduit 26. Further, when an excessive gas is generated in the gas separator 27, it is burned and consumed by the surplus gas combustion device 29.
Further, the gas cleaning storage water layer 25 of the gas cleaning tank 24 is pressurized by the pressurizing tank 30 and is introduced into the gas cleaning oil / water separation tank 31. Next, a description will be given of an embodiment of the method of the present invention. The white body excluding the engine, the tank, the glass, and the driving portion of the ordinary passenger car having a 3-liter engine is set in a bellows-shaped compression press, and the bellows is set. Open and close the lid 3 of the carbonization furnace 1 by pressing 5 pieces of a white body lump A, which is compression-molded to a diameter of 1,900 mm and a thickness of 250 mm by a compression press that presses in a biaxial direction of left, right, up and down. Then, it is put into the inner pot 2 of the carbonization furnace 1, the opening / closing lid 3 is closed, and the carbonization furnace 1 is heated using the heating burner 5 of the heating furnace 4. As the fuel for the heating burner 5, an oil-water emulsified mixture was used by adding an amount necessary for emulsifying the emulsifier to a previously stored mixture of pyrolysis oil and water at a mixing ratio of 50:50. The white body molded by compression press has paint applied on its surface, rubber coated rubber and resin molding material that cannot be easily removed, etc. The material is thermally decomposed into monomers, dimers or trimers, becomes oily, and a gaseous mixture thereof is cooled in the oil separation tank 7 to become oil. Further, pyrolyzed low molecular weight methane gas or ethane gas is used as a natural material. The process was terminated when the generated gas was not detected 6 hours after the start of the carbonization. [0021] 150 liters of oil obtained by this apparatus was obtained and stored in an oil tank. The weight of the metal, the inorganic substance and the carbide was 2500 kg. The carbon and other inorganic materials in the gaps of the compression-pressed pleats could be separated cleanly by the vibrator. This metal can be reused as a raw material for recycling. According to the present invention, it is possible to take out a metal by subjecting a scrapped vehicle to dry distillation without the generation of toxic gas and to reuse it as a raw material for recycling. Since there is no need to pulverize after compression, there is no bother and the cost is low. In addition, since a mixed oil of water and oil can be used, all the oil produced by dry distillation can be used as a fuel, and when a mixed oil obtained by emulsifying a mixed oil of water and oil produced with an emulsifier is burned, The generation of nitrogen oxides and sulfur oxides can be further suppressed to extremely low levels of carbon dioxide, and these oxides, which are sources of air pollution, can be suppressed to a safe range.
