In modern times, the rapid development of the automobile industry has increased the prevalence of vehicles, which in turn has increased the production of tires. In addition, as tire production increases, the disposal of used tires has become a social problem.

Waste tire is a high-energy polymer compound containing a large amount of isoprene and butadiene belonging to the hydrocarbon homologue, and since the state of decomposition in the air or in the strata is too delayed, it is mainly used by incineration. In other words, the waste tires are incinerated and waste heat generated at this time is used for thermal power plants or boilers. However, such an incineration method has a limitation in utilization because it not only pollutes the air by various harmful gases, dusts, etc. generated during the combustion of waste tires, but also limits the incineration sites.

Therefore, in recent years, the method of thermally decomposing waste tires which do not generate pollution with oil, pyrolytic carbon black, iron core or the like has been used. At this time, the pyrolysis carbon black which is directly discharged to the residue after pyrolysis is fine dust particles, and because it has high temperature thermal energy, an explosive reaction may occur when oxygen is encountered.

It comprises a wet scrubber 90 for filtering the exhaust gas generated in 20 to discharge to the outside.

Next, a dry pyrolysis carbon black discharge device according to the present invention will be described with reference to the accompanying drawings. Description of the above-described waste tire pyrolysis apparatus according to the present invention will be omitted.

2 is a conceptual diagram of a dry pyrolysis carbon black discharge device according to the present invention.

As shown in FIG. 2, the dry pyrolysis carbon black discharge device according to the present invention includes a cooling conveyor 410, a double flap damper 420, a hopper 430, a single flap damper 440, and a flow. A chain conveyor 450, a screw conveyor 460, a vibrating feeder 470, a magnetic separator 480, and a packing system 490.

The cooling conveyor 410 is for cooling and conveying a residue including pyrolysis carbon black discharged from the waste tire pyrolysis device and supplying the residue to the double flap damper 420. The cooling water passes around the screw of the cooling conveyor 410. Indirectly cooling the moving pyrolysis carbon black on the way. When the pyrolysis carbon black is cooled to some extent, the pyrolysis carbon black is transferred to the flow chain conveyor 450 through the double flap damper 420, the hopper 430, and the single flap damper 440. At this time, the most important thing in the treatment of pyrolytic carbon black is to maintain airtightness. That is, the pyrolytic carbon black discharged immediately after the pyrolysis reaction is fine dust particles, and has a high temperature thermal energy, and thus may explode with oxygen when airtight is not maintained. Therefore, it is preferable that the dry pyrolysis carbon black discharge device according to the present invention be manufactured in a sealed type so as to maintain airtightness.

The hopper 430 connects between the double flap damper 420 and the single flap damper 440 to supply a residue including pyrolytic carbon black, and is equipped with a high level detector. That is, the residue including pyrolysis carbon black passing through the cooling conveyor 410 is supplied to the hopper 430 and the single flap damper 440 through the double flap damper 420, and discharged from the single flap damper 440. The residue comprising pyrolytic carbon black is conveyed to the screw conveyor 460 via the flow chain conveyor 450. At this time, the high level detector attached to the hopper 430 automatically operates the flap damper by level sensing. That is, when the high level is detected by the high level detector, the cooling conveyor 410 is stopped and the upper double flap damper 420 is closed. In addition, when the upper double flap damper 420 is closed, the lower single flap damper 440 is opened to move the pyrolytic carbon black to the flow chain conveyor 450. After the pyrolysis carbon black is moved to the flow chain conveyor 450, the lower single flap damper 440 is closed and the upper double flap damper 420 is opened to operate the cooling conveyor 410 again. In other words, the present embodiment may apply a space securing and emergency closing structure in response to a problem that may occur when the pyrolysis carbon black is stagnated at the upper part by using a double flap damper.

In addition, the pyrolytic carbon black transferred to the vibration feeder 470 by the flow chain conveyor 450 and the screw conveyor 460 is classified according to the particle size by vibration in the vibration feeder 470, and the magnet separator 480 As it passes through the bottoms, traces of iron cores that are not removed by pretreatment, ie waste tire pyrolysis, are sorted out. The pure pyrolytic carbon black treated as described above is stored in a storage tank (not shown) and packed by a packing system 490 to produce a product.

Next, a slurry pyrolysis carbon black discharge device according to the present invention will be described with reference to the accompanying drawings. Description of the above-described waste tire pyrolysis apparatus according to the present invention will be omitted, and descriptions overlapping with the description of the dry pyrolysis carbon black exhaust apparatus according to the present invention will be omitted or briefly described.

3 is a conceptual diagram of a slurry pyrolysis carbon black discharge device according to the present invention.

As shown in FIG. 3, the slurry type pyrolysis carbon black discharge device according to the present invention includes a cooling conveyor 410, a double flap damper 420, a first hopper 430, and a single flap damper 440. The flow chain conveyor 450, the second hopper 510, the water reservoir 520, the slurry pump 530, the dryer 540, the condenser 550, and a packing system (not shown). Include. At this time, the double flap damper 420, the first hopper 430 and the single flap damper 440 of the present embodiment may be omitted or selectively installed according to the situation.

The second hopper 510 is to make the pyrolysis carbon black transferred from the flow chain conveyor 450 into a slurry form, and for this purpose, a water reservoir 520 is connected to the second hopper 510. In addition, the water at room temperature supplied from the water reservoir 520 is mixed with the pyrolytic carbon black to form a pyrolytic carbon black in the form of a slurry. Pyrolytic carbon black in the form of a slurry has a cooling effect than when discharged from a cooling conveyor, it is easy to maintain airtightness and is convenient for transport. In addition, a small amount of iron cores contained in the pyrolysis carbon black in the form of slurry that cannot be separated in the pretreatment, that is, the waste tire pyrolysis device, sinks under the second hopper 510 by the density. At this time, the iron core is separated into the lower portion of the second hopper 510 and the slurry pyrolysis carbon black is transferred to the dryer 540 using the slurry pump 530. In addition, steam generated when water is injected into the pyrolysis carbon black is preferably discharged to the outside (570).

The dryer 540 uses an indirect heating method using hot gas or steam. Since the water contained in the slurry pyrolysis carbon black becomes a vapor form only 100 degrees Celsius or more, the temperature of the hot gas or steam is maintained at 100 degrees Celsius or more. When indirect heating is performed in the dryer 540, the water is formed in the form of steam and exits to the upper part, and the dried pyrolytic carbon black is recovered from the lower part. Water vapor is made of water through a phase change process in the condenser 550 and then reused. Of course, a water tank 560 may be provided separately to store such water.

In addition, the post-treatment of the recovered pyrolytic carbon black can be installed according to the situation by using a screw conveyor (not shown), a vibrating feeder (not shown), a magnet separator (not shown), and a packing system (not shown). Can be sold by).

As described above, the pyrolytic carbon black discharge device according to the present embodiment has the advantage of easy airtight maintenance, easy movement and storage in the pyrolytic carbon black discharge process by using a slurry type pyrolysis carbon black discharge process method.

Although described above with reference to the drawings and embodiments, those skilled in the art can be variously modified and changed within the scope of the invention without departing from the spirit of the invention described in the claims below. I can understand.
