1 to 3, there is shown an oil recovery apparatus of a waste tire using an output variable microwave according to an embodiment of the present invention. The oil recovery device is a housing (Housing), which is generally denoted by 100, the input tank 110, the heating tank 120, the recovery tank 130, the extraction tank 140, the condensation tank 200 installed inside the housing 100 ) And a carbon black separation device 300 (see FIG. 3).

The housing 100 is adapted to extend laterally or longitudinally to facilitate the user's or operator's work, and each jaw 110, 120, 130, 140 is hermetically sealed, i. 102 is installed, which is operated by an automatic control device such as an automatic timer to provide a convenient and effective working environment.

Inside the housing 100, that is, the feed tank 110, the heating tank 120, the recovery tank 130, the take-out tank 140 is provided with a feeder 160 for continuously operating the moving tires This works in conjunction with the airlock 102 described above.

1 and 2, the housing 100 is formed integrally, it can be seen that the interior is divided into a multi-stage group. Each compartment of the compartment must be closed during operation for environmental pollution due to the discharge of harmful substances or for the safety of the workplace, which is sealed by the air lock 102 described above.

Various additional devices are provided in the present invention for the recovery of oil and carbon black. For example, in order to process the harmful gas generated in the housing 100 and some gas remaining after oilification to be released into the atmosphere or to recycle high-temperature gas (for example, air to nitrogen), Preferably, it includes a waste gas processor 400 for resupply to the heating bath 120, for this purpose, a heat exchanger 170 is installed inside the heating bath 120.

In addition, the above-described feeder 160 extends to the rear of the housing 100 and passes through the discharge bath 500 while transferring waste of the disassembled waste tires.

On the other hand, the idle tank 115 is formed between the input tank 110 and the heating tank 120 as shown. Here, it serves to supply nitrogen to the used waste tire, and to quickly discharge the steam containing oil to the condensation tank 200 during the waste tire decomposition work performed in the heating tank 120, and nitrogen The air lock 102 described above is operated during the operation for feeding, thereby closing the inside of the idle tank 115.

The heating tank 120 serves to extract the oil contained in the waste tire by oscillating microwaves in the waste tire. Preferably, the waste tire in the circular state can be continuously pyrolyzed at 35 kg / hr or more. Has performance. As shown in detail in FIG. 2, a distributor 122 is installed inside the heating bath 120 to uniformly heat and disintegrate the used waste tire. The distributor 122 induces uniform pyrolysis of waste tires by uniformly dispersing the oscillated microwaves, and serves to optimize the pyrolysis temperature.

Distributor 122 is connected to the waveguide 124 to guide and guide the incidence of the microwaves to be oscillated through it, it is preferable to form a structure of a closed duct to prevent leakage of the guided microwaves. The waveguide 124 has an output port 124a connected to the distributor 122 and extends outside the heating bath 120 to form the input port 124b.

The input port 124b of the waveguide 124 is equipped with a magnetron 126 for generating microwaves. Here, the microwaves emitted by the magnetron 126 change polarity up to billions of times per second, and the heating element vibrates according to the change of polarity. Due to the frictional heat generated thereby the heat generated inside the heating target. Thus, the pyrolysis temperature of the waste tire accommodated in the heating tank 120 of the present invention, which is heated by the magnetron 126, is maintained between 380 ° C and 450 ° C, and the temperature in the heating tank 120 is between 150 ° C and 350 ° C. In this case, the waste tires are decomposed into light to heavy oils and gases.

On the other hand, since the microwaves oscillated from the magnetron 126 are required to heat the heated object, that is, the waste tire, with minimal loss when incident on the waveguide 124, an insulator (not shown) is provided between the magnetron 126 and the waveguide 124. And a tracker (not shown) for detecting leakage propagation. At this time, the tracker to determine the transmission state after the leakage or propagation to the oscillator 128 according to the present invention to be described later to be able to freely vary the output.

The oscillator 128 described above is filed by the present applicant, the patent application No. 2000- 0004858 "ultra-high frequency heating device" can be applied. That is, the internal state of the heating tank 120 identified by the tracker not shown is transmitted to the oscillator 128 to freely adjust the output of the magnetron 126 to maintain the heating temperature set in the present invention at the best state.

The oscillator 128 should have the best energy efficiency, especially at 49%-64% efficiency, preferably at 50%-55% efficiency. That is, the power efficiency absorbed by the waste tire to satisfy the above conditions is as follows.

Therefore, when the total amount of electrical energy input is 100%, the efficiency of oscillation with microwaves is 70%-80%, the microwaves are heated with efficiency of 70%-80% to the waste tire without loss.

In addition, it is unique in the present invention is that the distributor 122 for outputting microwaves separately to the above-described heating bath 120 is arranged in two or more. This is to treat a large amount of waste tires, to be able to perform the processing capacity of 35 kg / hr or more of the object of the present invention.

1 and 3, the recovery tank 130 is a process for separating and recycling the carbon black of the waste tire decomposed in the heating tank 120, the above-described input tank 110, idle tank 115, the heating tank 120 is connected to each other and the take-out tank 140 to be described later, but consists of a structure that can be sealed to each other during operation.

In the present invention, the recovery tank 130 has a characteristic of heating up to 600 ℃ normally. This is to increase the purity of the carbon black to be decomposed, through which it is possible to increase the purity of the carbon black that can be taken out up to 85% up to 91%.

To this end, at least one distributor 122 mounted on the above-described heating tank 120 is also mounted to the recovery tank 130. As described above, the distributor 122 mounted on the recovery tank 130 heats the waste tire decomposed to 600 ° C., so that the distributor 122 should have a separate waveguide 124, a magnetron 126, and an oscillator 128. Of course.

The recovery tank 130 is provided above and below the waste tire so as to suck carbon black of the waste tire from which the suction pipe 132 is decomposed, and communicates with the outside of the recovery tank 130. The suction pipe 132 is located at the lower part of the feeder 160 and the upper part connected to the suction means equipped with the power unit due to the characteristics of the waste tires fed by the feeder 160.

As shown in detail in FIG. 3, the carbon black taken out through the suction pipe 132 is processed and separated by the carbon black separator 300, and preferably, the carbon black passed through the carbon black separator 300 is It is sorted and recovered in a state of 50 nm.

The hot carbon black introduced through the suction pipe 132 and the iron core mixed therein are transferred to the conveyor 310 to lower the temperature. The carbon black and the iron core whose temperature is lowered by the conveyance of the conveyor 310 are put into the hopper 320 and temporarily stored, and the carbon black and the iron core discharged through the hopper 320 have a uniform speed through the feeder 330. And are re-exported in amounts.

Since the carbon black and the iron core having passed through the feeder 330 are made of various sizes, they pass through the roller mill 340 which is pulverized to have a uniform size, preferably 50 nm. The roller miller 340 is preferably a roller-type mill, and the carbon black and the iron core are pulverized to a uniform size while passing therethrough.

Carbon black crushed to a certain size and the iron core are mixed with each other, so the iron core should be separated separately. To this end, the discharged, injected carbon black and the iron core passes through the magnetic roller 350 made of a magnetic conveyor. The magnetic roller 350 attaches the mixed iron cores to the conveyor to separate them, and at the same time, transfers the remaining carbon black to the outside and stores them. At this time, the rate at which carbon black is separated is taken out at a rate of 25% as compared with the circular waste tires.

The carbon black thus collected may be applied to various fields such as general rubber and resin fillers, belts or consumable rubbers, and battery materials, and may be mixed and applied to heat sources or road paving materials of cogeneration plants.

Again, as shown in FIG. 1, waste tires thermally decomposed by microwaves while passing through the heating bath 120 are decomposed into carbon black, iron core, and vaporized hydrocarbon in a solid state and are present in the heating bath 120. . The decomposed hydrocarbon and nitrogen gas is taken out to the condensation tank 200, and the above gases are liquefied and converted into oil through the condensation. Foreign oil is mixed in the converted oil, and the foreign matter affects the weight of the extracted oil, and is composed of oil of light weight or heavier weight. In the present invention, for this purpose, by installing two or more condensation tanks 200, a high quality oil may be obtained by performing a separate process by separating the oil in the separated light.

At this time, the above-described gas remaining after condensation into oil passes through the scrubber 220 to be desulfurized to be liquefied and then stored as oil.

As described above, the oil separated by condensation through the condensation tank 200 is stored in the state of oil or desulfurized gas by removing impurities by various methods.

Next, the oil recovery method of the waste tire using the output variable microwave and the effects thereof will be described in detail with reference to FIGS. 4 to 5.

Therefore, the heating bath 120 is made of a material that does not absorb microwaves, and must be able to withstand high temperatures of 600 ° C. and maximum pressure to be applied during decomposition.

As described above, two or more condensation tanks 200 may be installed to separate oils having various weights. The oil thus separated is retreated, that is, the post-treatment operation in the oil recovery step S300 is performed by sludge treatment, oil-water separation, hydrodesulfurization, and desulfurization agent addition at the same time to store oil or residual hydrocarbons.

The stored oil or hydrocarbon is used as a heat source of a generator, a boiler, and a steam generator, and the waste gas used and withdrawn is supplied back to the heating furnace 120 through the heat exchanger 170 to adjust the internal temperature of the heating furnace 120. Used to adjust.
