Description

Waste tire incineration and aftertreatment system {Apparatus for burning up used tires and treatment system thereafter.}

The present invention relates to a system for continuously incineration of waste tires, and more particularly, to enable continuous and smooth treatment in incineration of waste tires, and to improve the efficient use of exhaust gases as industrial energy. One waste tire incineration and aftertreatment system.

In general, since waste tires are caused by one industrial pollution, a method of incineration and disposal of the waste tires is mainly performed, and a waste tire incineration treatment apparatus is used.

The waste tire incineration treatment apparatus known to date includes Korean Patent Publication No. 1995-1465 and Patent Publication No. 1995-7416 invented by the present inventors. Utility Model Publication No. 1995-2884.

However, the above-mentioned prior arts have a system which is not automated or is divided into automatic processes for treating residues remaining before or after incineration of waste tires.

Therefore, the overall device and structure is complicated, the installation area must be large, and there is a problem that requires a lot of facility costs.

In addition, since it is impossible to continuously input the correct amount into the incinerator for incineration of waste tires, it cannot be regarded as a continuous incineration treatment.

In particular, waste tires should be accurately in size to ensure efficient incineration treatment, but since waste tires vary in size, the waste tires cannot be put into the incinerator continuously and accurately and thus do not promote efficient incineration treatment.

Moreover, in the waste tire incineration treatment, only the residues remaining after the waste tires are incinerated in the incinerator can be smoothly removed so that the continuous incineration treatment can be achieved.

However, the prior art (Korean Patent Publication No. 1995-7416) has been carried out a method for collecting the residue simply by dropping to the lower side, the residue was not smoothly removed.

Specifically, the tire has a thin wire (or wire mesh) inside the rubber member for durability. These wires do not burn, so they remain even when the waste tires are incinerated.

That is, since the rubber members constituting the tire are in the form of powder ash when incinerated, they can fall straight down. However, the wire mesh cannot be dropped immediately by being caught by the stole (or pedestal) supporting the waste tire.

Therefore, the incinerator can only be removed by pulling in one side. However, in such a case, incineration of waste tires must be stopped while the wire mesh is removed, thereby not only facilitating continuous incineration but also failing to fully automate and inefficient.

In addition, the problem of inability to effectively process the residues left after the incineration of waste tires and the post-treatment of incomplete combustion gas were not completely cleaned enough to be used as fuel. There is a problem brought about.

The present invention is intended to provide a waste tire incineration and post-treatment system that can achieve the full automation of the waste tire incineration treatment system while reducing the cost of the facility, and to maximize the waste gas recycling by increasing the continuous incineration treatment and waste gas cleaning efficiency. There is a purpose.

In order to achieve the above object, the present invention is to promote the automatic supply and post-treatment of waste tires using a hoist (HOIST) conveying device.

In addition, by supplying the waste tires to the pyrolysis furnace to sense the size of the waste tires, the appropriate amount of waste tires are put into the pyrolysis furnace for efficient incineration, and the residues remaining after incineration are automatically processed continuously. Was made.

Incomplete waste gas generated by incineration of waste tires can be almost completely cleaned by the cleaning apparatus, thereby maximizing the cleaning treatment efficiency, thereby achieving almost complete combustion even in the combustion of the cleaning gas to obtain thermal energy. It is characterized by.

The waste tire incineration and aftertreatment system according to the present invention will be more clearly understood on the basis of the attached preferred embodiments in more detail.

1 is a view showing a waste tire incineration and aftertreatment system according to the present invention. Referring to this figure, the waste tire supply processing unit 100 to be supplied for incineration of the collected waste tire T, the incineration unit 200 and the waste tire in which the waste tire T is incinerated and pyrolyzed are incinerated It will have an incineration residue treatment unit 300 for post-treatment of incineration residues P such as iron core, including the carbon powder remaining after the.

In addition, a system having a waste oil refinery processing unit 400 for storing and refining waste oil obtained as a by-product by waste tire incineration, and a waste gas cleaning processing unit 500 for cleaning waste gas obtained as a by-product also by waste tire incineration Are distinguished.

Referring to FIG. 1, the waste tire supply processing unit 100 includes a waste tire standby tank 110, and a hoist device 120 is installed on the waste tire standby tank 110. The hoist device 120 is already known as a conveying device, so detailed structure and description thereof will be omitted.

Therefore, when the waste tire T is collected by the collection vehicle C1, the waste tire is waited by the tongs 121 of the hoist device 120 in the state where the waste tire T is loaded on the collection vehicle C1. It is transported to the tank 110 and falls, whereby the waste tire T is in the standby state. Here, the hoist apparatus 120 continues to operate until it carries all the waste tires T of the collection vehicle C1.

Next, the hoist device 120 lifts the waste tires T in the waste tire standby tank 110 with the tongs 121 one by one and transfers them to the waste tire supply detection device 130 to drop to the guide hopper 131. At this time, the guide hopper 131 is such that the waste tire (T) is aligned.

2 and 3, the aligned waste tire T is supplied onto the chain conveyor 132. The chain conveyor 132 is driven by a motor power, and additional structures and descriptions such as a power relationship and a chain gear for driving are well known and thus will be omitted and described in connection with the characteristic structure.

That is, the tire guide member 133 is provided at equal intervals in the chain conveyor 132. Therefore, the waste tire T falls between the tire guide members 133 and is caught and is gradually transferred by the drive of the chain conveyor 132.

The size of the waste tire T is sensed in the process of being transferred. The detection means is detected by the large tire detection sensor 134, the medium tire detection sensor 135, and the small tire detection sensor 136 installed in the path where the waste tire T is transferred.

Therefore, in the process of transferring the waste tire T to the large, medium and small tire detection sensors 134 to 136, the state is detected according to its size, and the detection data is transmitted to the central processing circuit unit (not shown). The central processing circuit unit adjusts the amount of the inputted incinerator unit 200 with the sensed data.

For example, the speed and throughput at which the waste tire T is incinerated within 5 or 10 minutes in the incineration unit 200 are already obtained from the experimental data, and the waste tire T to be input by the experimental data. The dosage is determined.

In addition, when the size of the used waste tire T is sensed, since the waste tire T is standardized, its weight and volume can be known in advance, and the data is input to the central processing circuit.

Therefore, the waste tire T may be controlled so that a suitable amount is introduced into the incineration unit 200 according to the speed of the combustion treatment in the incineration unit 200, and the waste tire T is proportional to the amount of the waste tire T incinerated. ) Will be added continuously.

This waste tire supply detection device 130 allows to supply a proper amount of waste tire (T), so that it can have a continuous supply and full automation.

In addition, the waste tire is sensed as described above and before any water is injected into the inlet 220, the water may be removed from the inside of the waste tire T. If the waste tire is put together with water accumulated in the waste tire T, When incinerated, the combustion efficiency is significantly lowered, so that the waste water is removed before the injection.

2A and 3, the water suction port 138 sucks and discharges water by the water discharge pump 137. The water suction opening 138 is moved up, down, forward, and backward by the cylinders 139. Therefore, the water suction port 138 is inserted into the waste tire T to suck and remove the debris therein.

4 shows an elevation view of the incinerator 200. The incinerator 200 has a pyrolysis furnace 210, and the first shielding gate 221 and the second shielding gate 222 are provided at a predetermined interval in the inlet 220 provided at the upper end thereof.

Accordingly, the waste tire air space portion 223 is provided between the first and second shield gates 221 and 222. The first and second shield gates 221 and 222 are operated to move forward and backward by the pneumatic cylinder 224. The pneumatic unit for operating the pneumatic cylinder 224 is well known and thus will be omitted.

Referring to FIG. 5, the first shielding gate 221 is first opened when the waste tire T is inserted. And one waste tire (T) is introduced through the inlet 220 in the open state. The injected waste tire T is dropped on the second shielding gate 222 which is in a closed state and once waits for being placed thereon.

Next, the first shielding gate 221 is operated to close, followed by the second shield gate 222 to be opened.

Therefore, the waste tire T is introduced into the pyrolysis furnace 210, and the second shielding gate 222 is operated to be closed so that the inlet 220 is closed.

When the second shielding gate 222 is opened during the introduction of the waste tire T, the waste gas inside the pyrolysis furnace 210 instantly leaks to the outside through the inlet 220. For example, the waste gas is injected into the waste tire. Every hour leaks into the atmosphere will cause air pollution.

However, since the first shielding gate 221 is in the closed state at the upper end of the inlet 220, the waste tire air space portion 223 between the first and second shielding gates 221 and 222 in the closed state cannot be discharged to the outside. To stay).

Referring back to FIG. 1, waste gas in the waste tire air space portion 223 is introduced into the pyrolysis furnace 210 through the blower 240.

Therefore, it is possible to completely block the leakage of waste gas into the atmosphere through the inlet 220 when the waste tire (T) is injected, thereby preventing air pollution by waste gas leakage.

Referring to FIG. 4, the pyrolysis furnace 210 is sealed by the fuselage 211, the cover 212, and the conical residue dropping portion 213 at the lower portion thereof.

And inside the boundary portion of the fuselage portion 211 and the residue dropping portion 213 has a waste tire support portion 250 as shown in Figure 6, the waste tire support portion 250 is a waste tire (T) injected Will be supported.

Referring to FIG. 6, the skeleton of the waste tire support part 250 is an air supply pipe 260 required for combustion, and the air supply pipes 260 are installed to be fixed at regular intervals.

In addition, the air supply pipe 260 is connected to the main supply pipe 270 that receives the air from the blower 240 is to be supplied with air.

Referring to FIG. 7, a plurality of air discharge pipes 262 having a cover 261 are installed in the air supply pipe 260, and an air outlet 263 is drilled to the air discharge pipe 262. Therefore, air is injected to the side so that there is no blockage and smooth air injection is achieved.

According to FIG. 8, a reprocessing chain 281 that orbitally rotates by the chain gear 280 is installed between the air supply pipes 260 so as to be rotatable. In addition, the reprocessing chain 281 is provided with a V-shaped reprocessing member 282 as shown in FIG. 10 so as to stand up at equal intervals.

Referring to FIG. 9, the reprocessing chain 281 is rotated by a motor (not shown) power, and the reprocessing member 282 is moved horizontally. By this movement, the reprocessing member 282 pushes the incineration residues P such as the carbon material and the wire member, which are left after the waste tires are burned, to be moved to one side, whereby they fall to the residue falling portion 213. .

11 to 13 show the incineration residue treatment unit 300. Referring to FIG. 11, the incineration residue P falls from the residue dropping unit 213 to the residue compression unit 310. At this time, the predetermined amount may be adjusted by a damper or the like remotely controlled to fall.

The incineration residue P dropped into the residue compression unit 310 is moved by moving the first compression plate 321 straight by the first cylinder 320. Next, the second compression plate 331 presses the incineration residue P by the second cylinder 330 to compress the incineration residue P.

Next, as shown in FIG. 12, the third compression plate 341 compresses the incineration residue P by the third cylinder 340. At this time, the residue outlet 350 has a state blocked by the door 361 reciprocating by the opening and closing cylinder 360.

Therefore, the incineration residue P is pressurized by the third compression plate 330, at which time the waste oil contained in the incineration residue P is squeezed and flows down.

And the woven waste oil is discharged to the oil outflow hole 371 of the oil guide 370 in the lower portion as shown in Figure 13, the waste oil discharged in this way is dropped into the waste oil hopper 380 shown in Figure 12 waste oil refinery The oil is supplied to the processing unit 400.

In addition, when the waste oil is completely squeezed by the third compression plate 341, the incineration residue P becomes a compressed incineration residue in the form of a square cake. In this state, the compressed incineration residue is discharged to the outside through the residue outlet 350 when the door 361 is opened by the opening / closing cylinder 360 and the third compression plate 341 of the third cylinder 340 is further advanced. .

The compressed incineration residue thus discharged is transported by the conveyor 390 or the like and stored in the container 391 as shown in FIG. 1, but is lifted by the tongs 121 of the hoist device 120 to collect the vehicle. It is mounted on (C2) and transported and disposed of.

Referring to FIG. 1, when waste tires are incinerated in the pyrolysis furnace 210, waste oil and waste tires are burned and incineration residues such as carbon and wires and waste gas are generated. Here, the waste oil flows down the inner wall of the pyrolysis furnace 210, and the waste oil flowing down is concentrated in one place and is transferred to the outside to be integrated into the waste oil tank 290.

The waste oil of the waste oil tank 290 is transferred to the waste oil refinery processing unit 400 and refined to be reburned. The waste oil refinery treatment unit 400 is composed of an oil precipitator 410, an oil centrifuge 420, and an oil tank 430, and thus, detailed description thereof will be omitted.

Therefore, the waste oil that has been sent is stored in the oil tank 430 after the foreign matter such as suspended matters are removed while passing through the oil precipitator 410 and the oil centrifuge 420. And the oil of the oil tank 430 is sent to the emulsification (EMULSION) emulsifier 440 is emulsified.

The emulsifier emulsifier 440 adds an appropriate amount of water to the fuel oil to emulsify it continuously and at the same time finely decomposes sludge in the oil and precisely controls the preheating temperature to supply and burn the oil burner 610 to react with water gas. It is a device that promotes combustion to increase the combustion efficiency of the pollutants and to save fuel, wherein the waste oil emulsified is recycled by being injected through the oil burner 610 in the combustion device 600 such as a boiler.

Further, as shown in FIG. 1, the ignition fuel is supplied to the initial combustion burner 215 installed under the fuselage 211 of the pyrolysis furnace 210 to be combusted to ignite the waste tire at the beginning of operation. Is also used.

For reference, once the waste tires are ignited in the pyrolysis furnace 210, they are burned upward by the thermal power, so that the initial combustion burner 215 may not be continuously operated.

The waste gas discharged through the gas outlet 214 on the upper portion of the pyrolysis furnace 210 includes foreign substances such as dust and waste oil components. Therefore, the waste gas is discharged to the waste gas cleaning processing unit 500 to be cleaned.

The waste gas cleaning treatment unit 500 includes a first oil filter 510, an oil cooler 520, an oil cyclone 530, and a second oil filter 540. This waste oil cleaning treatment unit 500 is shown.

Referring to FIG. 14, in the first oil filter 510, filter members 512 having small holes punched in the iron plate are provided at equal intervals in the tank 511. Therefore, while the waste gas passes through the filter member 512, the waste oil including the foreign matter condenses on the surface thereof and flows down.

In addition, the waste oil flowing down is discharged to the waste oil refinery processing unit 400 through the drain hole 513. And again through the high pressure pump 550 is injected again through the oil nozzle 560a installed on the tank 511. Therefore, since the waste oil is injected into the waste gas flowing through the inlet 514, the dust contained in the waste gas is stuck to the state and falls down. As a result, the sprayed oil removes the dust contained in the waste gas, thereby further increasing the waste gas cleaning efficiency.

The next cleaning step will be described with reference to FIGS. 15 and 16.

The oil cooler 520 includes support plate members 522 on both sides of the tank 521, and a plurality of gas pipes 523 through which waste gas passes therebetween, and a water chamber 524 is formed therebetween. The water chamber 524 is configured to supply and drain the cooling water w through the import port 525 and the export port 526. The cooling water w supply is supplied to the cooling water tank 528 and is configured to be the cooling water circulation which is drained back thereto. Reference numeral 529 denotes a supplemental water tank for replenishing water to the cooling water tank 528.

Therefore, the waste gas is cooled by the cooling water w in the course of passing through the gas pipe 523. The waste oil is separated from the waste gas to be cooled. In addition, the separated waste oil is discharged to the waste oil refinery processing unit 400 through the drain hole (527). In addition, the sprayed oil is sprayed again through the oil nozzle 560b installed on the tank 521 through the high pressure pump 550 to remove dust contained in the waste gas and further increase the waste gas cleaning efficiency.

The next cleaning step is waste gas cleaning by the oil cyclone group 530 shown in FIG. The oil cyclone machine 530 is a waste gas flowing through the inlet 532 of the tank 531 flows into the inlet 533, the propeller 535 is rotated by the power of the motor 534 in the inlet 533. By this, waste gas is forcibly rotated and discharged.

Therefore, the waste oil contained in the waste gas rotated like a whirlwind is separated by hitting the propeller 535. The separated waste oil is discharged to the waste oil refinery processing unit 400 through the drainage port 536.

In addition, the oil sprayed by spraying again through the oil nozzle 560c installed on the tank 531 through the high pressure pump 550 removes dust included in the waste gas and further improves the waste gas cleaning efficiency.

In the oil cyclone group 530, at least two propellers 535 may be installed to increase processing speed and efficiency.

The waste gas exhausted from the oil cyclone machine 530 passes through the fine holes 543 of the filter member 542 installed in the tank 541 of the second oil filter 540 shown in FIGS. 18 and 19. It is cleaned by the same principle as the first oil filter 520.

In addition, the waste oil well 544 is discharged to the waste oil refinery treatment unit 400.

In addition, the oil sprayed through the oil nozzle 560d installed in the upper portion of the tank 541 through the high pressure pump 550 removes the dust contained in the waste gas and further improves the waste gas cleaning efficiency.

Therefore, the waste gas from which noxious components including dust are cleaned is supplied to the oil burner 610 of the combustion device (or apparatus) 600 to be combusted. At this time, the oil burner is supplied from the waste oil refinery processing unit 400 to the oil burner 610. By supplying the clean waste gas and the refined waste gas is mixed in the oil burner 610 to be burned.

In addition, the cleaned waste gas can be injected by the nozzle 620 toward the fire chamber of the combustion device 600, as shown in FIG.

Therefore, when the combustion device 600 such as a boiler and the waste tire incineration and aftertreatment system of the present invention are installed together, the waste oil and waste gas can be recycled together with the incineration of the waste tire, thereby achieving economical efficiency.

As shown in FIG. 20, the installation area can be minimized by installing all the devices in one place, and in particular, the compressed incineration residues treated after the waste tire T supply and incineration by the hoist device 120 are collected. It is possible to operate the system as a fully automated processing system by allowing the vehicle to be loaded at (C2).

According to the above description, the waste tire incineration and the waste tire incineration treatment system can be fully automated while reducing the installation area and facility cost, and the continuous incineration and waste gas cleaning efficiency can be maximized for recycling into fuel. There is an effect to provide a post-processing system.
