The present invention extracts fuel oil from gas and steam produced by thermal decomposition of waste tire fragments by dry distillation furnace, and heat which separates recyclable by-products such as carbon and metal from other by-products by wet method, not dry method. The present invention relates to an apparatus for separating recycled byproducts of decomposed waste tires.

In general, waste tires are composed of at least 50% of a polymer compound, about 30% carbon, about 20% iron core or fiber, and inorganic additives.

If such waste tires are disposed of as they are, there is a serious problem that sulfur contained in the rubber of the waste tires not only pollutes the ecosystem such as soil, but also incurs a great amount of toxic gas and soot when it is incinerated. there was.

Thus, the waste tires were pulverized into small pieces and thermally decomposed by a dry distillation furnace, but the fuel oil was extracted and recycled byproducts such as carbon and metal were recovered.

As such, a device for separating fuel oil and carbon, metal, etc. from waste tires has been known in a number of forms, which will be described below with reference to Korean Patent Publication No. 2004-110292.

This is supplied to the crushed waste tire through one side hopper of the distillation furnace, the distillation furnace is thermally decomposed as the waste tire fragment is moved into the distillation by the screw provided therein while rotating in the linkage drive by the drive motor It goes through the process.

That is, the waste tire fragments are thermally decomposed by the high heat radiated from the external heating device of the dry distillation furnace and the high temperature saturated steam (about 500 ° C.) injected by the steam generator into the dry distillation furnace, thereby decomposing the gas, steam and the By-products such as carbon and metal are emitted.

The gas and steam condense through cooling by a cooler and a storage tank, thereby extracting fuel oil. At this time, the surplus gas and steam may be reused as a fuel for driving a heating device in a dry flow furnace.

In addition, the by-products, such as carbon and metal, are discharged through the outlet of one side by dry distillation and moved by the conveyor to separate and recycle carbon and metal by a separate separation device.

In other words, the carbon and metal by-products are first separated from the metal, and the carbon and the metal are separated and extracted separately by a separate separation device, and the other sludge is disposed of.

However, the conventional apparatus described above has the following problems.

First, the prior art has a problem that the explosion risk is included.

That is, by-products such as carbon and metal discharged from the drying furnace are separated in a dry state, and the carbon and metal just discharged from the drying furnace are supplied with gas at a high temperature so that they are supplied to a metal conveyor. During the drop transfer process, there was a risk of explosion due to the friction of metal chips and conveyor friction sparks.

In addition, high pressure is generated because gas and vapor are generated in a high temperature state in the dry distillation furnace, and if the pressure state is not constant, there is a risk of fatal explosion such as a bomb when overpressure is taken.

In addition, there is a risk of explosion by providing the cause of the explosion as the outside air is introduced through the hopper into which the waste tire fragments are introduced, the explosion risk inside the dry distillation furnace.

Of course, in order to block the inflow of external air through the hopper, in the Republic of Korea Utility Model No. 388239, the raw material improvement valve, the first and second air shutoff valves are sequentially opened and closed while supplying the waste tire slices to the hopper. Attempted to block the inflow of external air, but this was not able to block the incoming air during the process of opening and closing the valve, there was a problem that can not completely block the external air through the hopper, thereby causing the internal ignition cause by dry There was a problem to some extent provided.

Second, the prior art has a problem of causing environmental pollution.

That is, during the process of thermal decomposition in the distillation furnace or during the process of discharging and separating by-products such as gas, steam, and other carbon and metals generated by thermal decomposition, various harmful gases and odors are generated. Because it becomes.

Third, the conventional technology is provided with separate devices for separating and treating various by-products discharged from the dry distillation furnace, so that the apparatus is enlarged and the separation effect is also lowered because the characteristics of each by-product are not considered. There was a problem.

On the other hand, despite the numerous patents related to such waste tire recycling apparatus has been disclosed, safety problems such as explosion risk, environmental pollution of waste water and air, and profitability problems due to failure to effectively separate recycling by-products, resulting in industrial use Most of them were practically impossible to be used due to the problem of possibility.

In particular, the Republic of Korea Patent Publication No. 2004-110292 described above is described as a possible configuration of the overall system, but each implementation means for solving the problem was not specifically presented, the explosion and the dry separation method described above Other problems such as safety and profitability against pollution have emerged seriously, which has been a problem that cannot be realized.

Therefore, the present applicant has been devoted to research and development in order to improve the problems of the prior art as well as a number of conventional waste tire recycling apparatus, by-products such as carbon, metal, etc. discharged from the drying furnace in the Republic of Korea Patent Application No. 2005-396121 In the space where the outside air is blocked, it also separates the carbon and metal in the water, thereby solving the risk of explosion and air pollution due to harmful gases.

In addition, the metal and carbon, which are primarily separated from the water, are collected and moved by vibrating screen conveyors rather than separate devices, thereby intensively collecting and minimizing equipment and maximizing the separation efficiency of carbon and metal. Could.

However, the above applicant's prior application technology alone could not completely overcome the problems of the prior arts described above, and there was a problem that newly occurred in the applicant's prior application technology, which caused the carbon and metal in the water. When separating, the temperature of water rises rapidly due to the high temperature of carbon and metal, which causes evaporation of harmful gases and vapors to the outside, resulting in safety risks, and water contained in the process of transferring the by-products by the screen conveyor. Various problems have occurred such that fine carbon powder is not completely transported and discharged, and some of them are not transported smoothly because they are re-transferred while stuck to the screen of the conveyor.

Therefore, the present applicant completely compensates for various problems arising from the prior application technology of the present applicant as well as a number of waste tire recycling apparatuses in the related art, thereby ensuring safety and profitability against explosion and other pollution, and thus industrial availability. This has led to the development of technology.

The present invention has been created to fundamentally solve all the problems of the above-described prior application technology and a number of prior arts by the present applicant to provide a practically perfect device.

The present invention separates the by-products of the waste tire pyrolyzed by the drying furnace by the wet method, not by the conventional dry method, and prevents the high pressure inside the drying furnace by blocking the inflow of external air into the drying furnace through the hopper. The purpose is to maximize safety because it prevents.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment for achieving the object of the present invention will be described in detail.

As the present invention is shown in Figure 1 to 10,

The fragments from the waste tires are fed into the distillation furnace (5) through one side hopper (2) and moved by the screw (6) in the rotation of the distillation furnace to generate high heat and steam generators ( 8) The gas and steam generated through the thermal decomposition process by the high temperature steam injected by condensation through the cooling process by the cooler and the storage tank are condensed and the fuel oil is extracted. By means of means 20, 25, carbon, metal, etc. are separated,

The by-product secondary separation means 25 is recycled by separating and collecting carbon, metal, etc. while again feeding the by-product separated to the screen conveyor 22 of the primary separation means and transported by the vibrating screen conveyor 26 again. In doing

The water tank tank 21 of the by-product primary separation means 20 is formed by connecting the cooling tower 31 to the drain pipe 21a and the water supply pipe 21b so that the precipitated water in the water tank tank 21 reaches a predetermined temperature or more (P1). Precipitate water cooling by forcibly draining through the drain pipe (21a) through the cooling tower (31) to circulate through the water supply pipe (21b) to cool the precipitated water in the water tank (21) below a predetermined temperature. Means 30 are provided.

In addition, the cooling tower 31 has a separator 32 having an inclined screen 32 'on the upper side to separate the by-product from the sediment water drained from the water tank tank 21 to the upper left and right and filtered on the inclined screen. The by-products are separately collected along the slope, and the sedimented water collected in the separator is fed to the left and right cooling chambers 35 at the bottom for cooling.

The cooling chamber 35 is cooled by air sucked from the outside to the inside by the intake fan 37 in the center of the left and right cooling chambers 35 while the precipitated water is guided downward along the zigzag guide plate 36. It is collected at 38 and is circulated to the water tank 21.

At this time, the cooling tower 31 is formed in succession to form a plurality of separation cylinders 32, 33 having screens 32 'and 33' inclined to the upper left and right in upper and lower portions of the upper screen is finer than the upper screen. The sedimented water in the upper separator (32), which is first filtered through the upper screen, is passed through the lower screen to the lower screen to separate the by-products filtered in multiple stages on the upper and lower screens separately along the slope, and the lower separator (33). Precipitated water collected in the supply to the lower left and right cooling chamber 35 may be configured to cool.

In addition, a plurality of air nozzles 45 connected to the air pump P2 are installed in the width direction on the inner upper portion of the screen conveyor 22 of the by-product primary separation means 20 to the high pressure air injected from the air nozzles. And carbon removal means 40 for separating carbon by-products stuck to the screen 22a.

In addition, an outlet 52 connected to the incinerator 55 is formed in the distillation furnace 5, and when a predetermined pressure or more is detected by the pressure gauge 51, the opening and closing valve 53 of the outlet is opened and closed, and an exhaust fan is provided. And a gas pressure reducing means 50 for driving the 54 to reduce the pressure inside the distillation furnace while incineration discharges the high-pressure gas, steam, and the like inside the distillation furnace 5 from the incinerator.

The hopper 2 is formed with a plurality of compartments 64, 65 by the diaphragm 61, 62, 63 to block the internal injection hole (2a) up and down to open and close in sequence while sliding the diaphragm Injecting the tire pieces, the lower compartment 65 is provided with an external air blocking means 60 to block the inflow of external air by the vacuum suction operation by the vacuum pump (P3).

As not shown, M1, M2 is a driving motor for driving the section feed screw inside the distillation furnace and distillation furnace, 21c is a water injection nozzle for generating the flow of sediment in the water tank tank 21 to move the float to one side Flow generating means such as 27, respectively represents the vibration means for generating vibration on the screen while the cam operation in the lower portion of the screen conveyor (26).

Next will be a look at the operation and action of the subject innovation configured as described above.

First, the present invention is to put the pieces of the waste tires primarily shredded by the shredding device through the hopper (2) of the distillation furnace (5).

At this time, the dry flow path (5) is driven by a separate drive means to form a high temperature and high pressure state by the high heat generated by the heater 7 and the high temperature steam injected by the steam generator (8). .

Therefore, it is essential to block external air from flowing into the dry distillation furnace 5 when the waste tire fragment is introduced through the hopper 2.

In the present invention, the upper partition 61 is opened by the operating cylinder 61 'when the waste tire section is inserted through the hopper 2 as shown in FIGS. 9A, B and C, and the section is preferentially the upper compartment 64. To be put into

In this state, the upper diaphragm 61 is blocked and the lower diaphragm 62 is opened by the working cylinder 62 'so that the waste tire fragments fall into the lower compartment 65.

As such, when the waste tire fragment is introduced into the lower compartment 65, the diaphragm 62 is blocked again, and the external air introduced together with the fragment is discharged to the outside by the vacuum pump P3 to release the lower compartment 65. Form in vacuum.

In this state, the bottom diaphragm 63 is opened by the operation cylinder 63 'so that only pure waste tire fragments excluding the inflow of external air can be supplied into the drying furnace 5 through the hopper 2. .

As a result, the risk of explosion is prevented by blocking the inflow of external air into the distillation furnace 5 at high temperature and high pressure.

In this way, the waste tire fragments supplied into the distillation furnace 5 are moved by the screw 6 inside by the rotation of the distillation furnace, and the high temperature generated by the heater 7 and the high temperature sprayed by the steam generator 8. The steam undergoes thermal decomposition.

At this time, the inside of the drying furnace 5 also contains a risk of explosion due to high temperature and high pressure.

For this reason, in the present invention, when the pressure gauge 51 provided on the outlet 52 detects the pressure inside the drying path 5 and exceeds a predetermined pressure, the on / off valve 53 is opened and the exhaust fan 54 is opened. Will be activated.

Therefore, the gas and vapor inside the dry distillation furnace 5 are sucked through the outlet 52 and not discharged to the atmosphere as it is, but are incinerated by the incinerator 55, thereby releasing various harmful components into the atmosphere in the state of decomposition. In other words, the incineration ash will be separated.

When the pressure inside the distillation furnace 5 falls below a predetermined pressure, the pressure gauge 51 is again sensed to shut off the opening / closing valve 53 and stop the operation of the exhaust fan 54.

Therefore, the explosion risk inside the distillation furnace 5 is completely blocked.

On the other hand, as described above, by thermal decomposition of the waste tire fragments in the drying furnace 5, by-products such as gas, steam, carbon, and metal are generated in the drying furnace 5.

The gas and steam condense through cooling with a cooler and a storage tank, thereby extracting fuel oil, and discharging the by-products such as carbon and metal to discharge carbon by-products 1, 2, and the second separation means 20 and 25. , Metal and so on.

In more detail, by-products such as high-temperature carbon and metal discharged from the drying furnace 5 are introduced into the sedimentation water in the tank 21.

As such, by-products such as high temperature carbon and metal introduced into the sedimented water reduce the temperature of the by-product by the sedimented water, thereby preventing the explosion hazard that may occur when colliding with the metal material.

In addition, the precipitated water is cooled by the cooling tower 31 because the precipitated water is rapidly raised to a high temperature (approximately 80 ° C. or more) by the by-products of high temperature carbon, metal, and the like introduced into the precipitated water in the tank 21 as described above. By continuously circulating and supplying the immersion water temperature in the water tank 21 is kept constant.

This is forcibly draining the sediment water through the drain pipe 21a connected to the water tank tank 21 by the pump P1 and supplying the sedimentation water to the separators 32 on the left and right sides of the cooling tower 31, respectively. By-products included in the sedimentation water are separated and discharged along the inclination of the inclined screen, and the sediment water passing through the screen is collected in the separator 32.

And once again the precipitated water collected in the upper separator 32 is supplied to the lower separator to separate the by-product contained in the precipitated water again by the inclined screen 33, the inclined screen 33 ' Particles are finer than the inclined screen 32 'of the upper separator 32 so that smaller by-products are separated and discharged along the inclination of the inclined screen 33, and the precipitated water passing through the screen is separated into a separator ( 33).

The sedimented water collected in the separator 33 in the state of separating the by-products is guided downward along the zigzag guide plate 36 provided in the cooling chamber 35 on the lower left and right sides of the left and right cooling chamber 35. Cooled by the air sucked from the outside to the inside by the intake fan 37 provided in the center is collected to the lower collection chamber 38.

The precipitated water in the cooling state collected in the collection chamber 38 is recycled back into the tank tank 21 through the water supply pipe 21b, so that the temperature of the precipitated water in the tank can be kept low.

As described above, the process of separating the by-products such as high-temperature carbon, metal, etc. discharged from the dry distillation furnace (5) in the tank tank 21, the dispersion of carbon, metal and the like introduced into the precipitated water is suspended once Or sink.

The by-product filtered on the screen 22a of the lower screen conveyor 22 while floating or sinking is discharged to the outside of the tank tank by the screen conveyor 22 and collected separately.

In addition, the by-product precipitated on the bottom of the tank tank 21 through the screen 22a of the screen conveyor 22 is scraped by the bucket of the discharge conveyor 23 and discharged to the outside of the tank tank to be collected separately.

At this time, the by-products that are suspended or filtered by the screen conveyor 22 are lumps in which carbon and metal are entangled, and the scraped and discharged from the bottom of the tank tank becomes carbon powder.

In particular, the by-products separated and discharged to the screen conveyor 22 are dropped again at the end of the conveyor and transported by the vibrating screen conveyor 26 to undergo the separation process of the carbon and metal again.

At this time, the screen 22a of the screen conveyor 22 is carbon powder together with water so that it is not discharged to the lower screen conveyor 26 can be circulated into the water tank 21 along the conveyor 22. This is because a plurality of air nozzles 45 installed in the width direction on the inner upper portion of the conveyor 22 injects the high-pressure air supplied by the air pump (P2) to the carbon powder adhering to the screen of the conveyor 22 It will be supplied to the screen conveyor 26 without leaving.

In this way, the by-products supplied to the screen conveyor 26 are collected separately by separating the carbon and the metal during the process of vibrating the screen up and down by the vibrating means 27.

As described above, the present invention separates the by-products of the waste tire pyrolyzed by the distillation furnace by the wet method rather than the conventional dry method, and prevents the high pressure inside the distillation furnace by introducing the outside air into the distillation furnace through the hopper. Maximizes safety by preventing explosion risks, and also releases various harmful gases, odors, and waste water to the outside in the process of separating or discharging by-products such as pyrolyzed gas, steam, and other carbon and metals It prevents the environmental pollution by completely preventing the environmental pollution, as well as constituting various facilities for the separation treatment of various by-products discharged from the dry distillation furnace to reduce the overall size while maximizing the separation treatment efficiency of various by-products As well as the previously filed technology, various problems arising in the conventional waste tire recycling apparatus It has the effect of perfecting the perfection of profitability and industrial availability.
