Description

Technical Field

[0001] This invention relates to the field of desulfurization technology for recycled rubber, specifically a desulfurization treatment device and method for recycled rubber from waste tires. Background Technology

[0002] One of the main ways to recycle and process waste tires and other rubber products is to produce recycled rubber. Recycled rubber can replace some of the raw rubber in the production of various rubber products, which can reduce the waste of raw materials and improve the utilization rate of waste tires.

[0003] In the process of recycling waste tire rubber, desulfurization is a key step in the production of reclaimed rubber. With continuous technological breakthroughs, the desulfurization process has become more and more perfect, and the quality of reclaimed rubber is becoming more and more similar to that of raw rubber.

[0004] As people's environmental awareness increases, the problem of exhaust gas emissions after desulfurization is attracting more and more attention. Specifically, desulfurization produces a large amount of odorous gases carrying non-methane total hydrocarbons. If these gases are directly emitted, they will impact the ecological environment. Therefore, existing desulfurization exhaust gases are first sprayed and purified before being cooled and discharged. Although spraying and purification has a certain cooling effect, it is not significant. Therefore, additional cooling processes are needed, making the entire exhaust gas treatment system more complex and energy-intensive, which is not conducive to the optimization of the recycled rubber process. Summary of the Invention

[0005] The purpose of this invention is to provide a desulfurization treatment device and method for recycled rubber from waste tires, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A desulfurization treatment device for recycled rubber from waste tires includes: a crushing device, a screening device, a sieving device, a desulfurization device, and a tail gas treatment device.

[0008] The exhaust gas treatment device includes:

[0009] A processing tank, on which a gas guide pipe is installed, the gas guide pipe having an "L" shaped structure;

[0010] The support arm is arranged in a circular pattern with multiple sets and connected to the air guide pipe. The support arm has multiple pressure relief ports equidistantly arranged on the side facing the bottom of the treatment tank.

[0011] A pressure sensing component is connected to the air duct, and the pressure sensing component can drive the support arm to move toward or away from the bottom of the processing tank according to the pressure in the air duct.

[0012] A baffle plate is installed inside the treatment tank and cooperates with the pressure relief port to enable the gas and liquid inside the treatment tank to rotate.

[0013] A linkage component connects the air pressure sensing component and the guide plate. When the pressure inside the air duct changes, the linkage component can drive the guide plate to rotate to change its deflection angle.

[0014] As a further aspect of the present invention: a plurality of strip-shaped through grooves are equidistantly arranged on the air guide pipe, and a connecting sleeve connected to and communicating with the support arm is slidably installed on the air guide pipe. The connecting sleeve is connected to the air pressure sensing component, and when the connecting sleeve moves on the air guide pipe, the strip-shaped through grooves are always inside the connecting sleeve.

[0017] The air pressure sensing component includes a branch pipe disposed on and connected to the air guide pipe. A sealing plug is slidably installed inside the branch pipe. A connecting shaft perpendicular to and passing through the branch pipe is connected to the sealing plug. A cylindrical spring is sleeved on the connecting shaft. One end of the cylindrical spring is connected to the sealing plug, and the other end is connected to the inner wall of the branch pipe.

[0018] The end of the connecting shaft away from the sealing plug is also connected to a slider, and the slider is slidably connected to the groove.

[0019] As a further embodiment of the present invention: the air pressure sensing component further includes a traction rod rotatably connected to the slider, and the end of the traction rod away from the slider is rotatably connected to the communicating sleeve.

[0020] As a further embodiment of the present invention: the linkage component includes a collar slidably sleeved on the communicating sleeve and a right-angle connecting arm formed at the end of the traction rod away from the slider, a support rod is rotatably mounted on the right-angle connecting arm, and the support rod is rotatably connected to the collar;

[0021] The linkage component also includes a traction structure that connects the collar and the guide plate.

[0022] As a further embodiment of the present invention: the traction structure includes a derivative rod connected to the collar, and a pulley is rotatably mounted on the end of the derivative rod away from the collar;

[0023] The guide plate has a hysteresis groove on the side facing the connecting sleeve, and the pulley can roll in the hysteresis groove.

[0024] As a further embodiment of the present invention, the exhaust gas treatment device further includes:

[0025] The outlet and inlet structure are connected to the treatment tank, and the inlet structure can control the speed at which the purified liquid enters the treatment tank;

[0026] A transmission assembly connects the slider and the guide structure. When the slider moves, the transmission assembly can drive the guide structure to move.

[0027] As a further embodiment of the present invention: the inlet structure includes an inlet port communicating with the processing tank, a rotary connector is slidably and sealed on the inlet port, the rotary connector is connected to the transmission assembly, and an extension interface is slidably and sealed at the end of the rotary connector away from the inlet port.

[0028] The inlet and the end opposite to the rotary connector have a right-angled arc-shaped through groove that fits each other.

[0029] As a further embodiment of the present invention: the transmission assembly includes a horizontal shaft connected to the slider, and a drive rod is connected to one end of the horizontal shaft away from the slider. The outer surface of the drive rod is provided with a spiral groove along its length.

[0030] The transmission assembly further includes a follower sleeve rotatably connected to the processing tank. The follower sleeve is connected to the rotating connector via a belt, and a convex shaft capable of sliding within the spiral groove is formed inside the follower sleeve.

[0031] A method for regenerating rubber from waste tires using the desulfurization equipment as described in claims includes the following steps:

[0032] Step 1: Place the cleaned waste tires into the crushing device to break them into granules, and use a dust removal device to remove the dust generated during the crushing process.

[0033] Step 2: Pour the waste tire pellets into the screening equipment to separate the tire cord fibers, steel wires, etc. from the waste tire pellets;

[0034] Step 3: Screen the waste tire particles to separate out those that do not meet the particle size requirements and then crush them again.

[0035] Step 4: Pour the sieved waste tire particles into the desulfurization device, and at the same time add a predetermined proportion of softener, activator, and water into the desulfurization device and mix them. Then, through heating, pressurization, oxidation, etc., the network structure of its molecules is destroyed, so that the waste tire particles change from an elastic state to a plastic state.

[0036] Step 5: Use a tail gas treatment device to purify and cool the non-methane total hydrocarbons generated during the desulfurization process.

[0037] Compared with the prior art, the beneficial effects of the present invention are:

[0038] By incorporating support arms and pressure sensing components, the exhaust gas can directly react with the purification liquid as it enters the treatment tank. This improves the purification rate of non-methane hydrocarbons in the exhaust gas and enables more effective cooling of the exhaust gas, facilitating subsequent treatment. Furthermore, as the speed at which the exhaust gas enters the purification liquid changes, the height of the pressure relief port in the purification liquid also changes accordingly. This ensures that the exhaust gas has a longer residence time in the purification liquid at the corresponding speed, further improving the purification rate of non-methane hydrocarbons and the cooling effect on the exhaust gas.

[0039] By using the baffle and linkage components, the exhaust gas ejected from the pressure relief port will spiral under the action of the baffle, which further improves the movement path of the exhaust gas in the treatment tank, so that the exhaust gas can be better purified and cooled. At the same time, driven by the exhaust gas, the purification liquid can rotate and generate turbulence. The generation of turbulence improves the heat exchange effect between the exhaust gas and the purification liquid, making the cooling effect of the purification liquid on the exhaust gas more significant. In addition, the angle of the baffle is linked to the jet speed of the exhaust gas, which has the effect of preventing the exhaust gas from directly gushing out of the purification liquid.

[0040] By designing the import structure and transmission components, the amount of purification liquid entering the treatment tank changes with the speed and volume of the exhaust gas entering the purification liquid, thus achieving automatic matching between the two. This ensures that the purification liquid can be mixed with the exhaust gas in a predetermined ratio, so that the predetermined amount of purification liquid has both good purification and cooling effects.

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0054] Please see Figures 1-10 In this embodiment of the invention, a desulfurization treatment device for recycled rubber from waste tires includes a crushing device, a screening device, a sieving device, a desulfurization device, and a tail gas treatment device.

[0055] The exhaust gas treatment device includes a treatment tank 1, a support arm 4, a pressure sensing component, a guide plate 15, and a linkage component. This allows the exhaust gas to directly enter the purification liquid and react with it when it enters the treatment tank 1. This improves the purification rate of non-methane total hydrocarbons in the exhaust gas and enables more effective cooling of the exhaust gas, facilitating subsequent treatment. Furthermore, as the speed at which the exhaust gas enters the purification liquid changes, the height of the pressure relief port 401 in the purification liquid also changes accordingly. This ensures that the exhaust gas has a longer residence time in the purification liquid at the corresponding speed, further improving the purification rate of non-methane total hydrocarbons and the cooling effect on the exhaust gas.

[0056] Specifically, the treatment tank 1 is equipped with a gas guide pipe 2, which has an "L" shaped structure, and the treatment tank 1 is provided with an air outlet at the top, through which the purified exhaust gas is discharged.

[0057] The support arm 4 is arranged in multiple sets in a circle and is connected to the air guide pipe 2. The support arm 4 is provided with multiple pressure relief ports 401 at equal intervals on the side facing the bottom of the treatment tank 1.

[0058] The air guide pipe 2 is provided with a plurality of strip-shaped through grooves 201 at equal intervals around its circumference, and a connecting sleeve 3 connected to and communicating with the support arm 4 is slidably installed on the air guide pipe 2. The connecting sleeve 3 is connected to the air pressure sensing component, and when the connecting sleeve 3 moves on the air guide pipe 2, the strip-shaped through grooves 201 are always inside the connecting sleeve 3.

[0059] The air pressure sensing component is connected to the air guide pipe 2, and the air pressure sensing component can drive the support arm 4 to move toward or away from the bottom of the processing tank 1 according to the pressure in the air guide pipe 2.

[0060] The processing tank 1 is equipped with a bracket 10 that connects to the air guide pipe 2, and the bracket 10 is provided with a sliding groove 1001;

[0061] The air pressure sensing component includes a branch pipe 5 disposed on and connected to the air guide pipe 2. A sealing plug 6 is slidably installed inside the branch pipe 5. A connecting shaft 7 perpendicular to and passing through the branch pipe 5 is connected to the sealing plug 6. A cylindrical spring 8 is sleeved on the connecting shaft 7. One end of the cylindrical spring 8 is connected to the sealing plug 6, and the other end is connected to the inner wall of the branch pipe 5.

[0062] The end of the connecting shaft 7 away from the sealing plug 6 is also connected to a slider 9, and the slider 9 is slidably connected to the slide groove 1001.

[0063] The air pressure sensing component also includes a traction rod 11 rotatably connected to the slider 9, and the end of the traction rod 11 away from the slider 9 is rotatably connected to the communicating sleeve 3.

[0064] In use, the air guide pipe 2 and the air outlet are connected to the corresponding pipeline. When the gas enters the air guide pipe 2, it will enter the connecting sleeve 3 through the strip groove 201, and then enter the support arm 4 through the connecting sleeve 3. Finally, it will be discharged into the purification liquid in the treatment tank 1 through the pressure relief port 401. The purification liquid reduces the non-methane total hydrocarbon content in the exhaust gas by reacting directly with the exhaust gas. At the same time, the exhaust gas and the purification liquid can exchange heat to reduce the temperature of the exhaust gas, making the purified exhaust gas purer and the temperature relatively lower, which is convenient for subsequent treatment of the exhaust gas. Based on the above principle, compared with the traditional spray purification method, the purification method adopted in this embodiment is obviously more reliable and also has a better cooling effect.

[0065] It is worth noting that during the desulfurization process, the rate of exhaust gas generation is not constant. The exhaust gas entering the gas duct 2 and exiting through the pressure relief port 401 will also have a non-constant velocity. In this embodiment, when the exhaust gas enters the purification liquid, buoyancy is generated. If the pressure relief port 401 is located at the bottom of the treatment tank 1, when the exhaust gas ejected from the pressure relief port 401 has a high velocity, the exhaust gas contacts the bottom of the treatment tank 1 and moves in the opposite direction, resulting in a shorter retention time of the exhaust gas in the purification liquid within the treatment tank 1. If the pressure relief port 401 is set on the upper layer of the liquid surface in the treatment tank 1, when the exhaust gas ejected from the pressure relief port 401 is slow, the buoyancy of the exhaust gas will cause it to rush out of the purification liquid surface quickly. At this time, the residence time of the exhaust gas in the purification liquid is also short. Both situations indicate that when the speed at which the exhaust gas enters the purification liquid changes, the height of the pressure relief port 401 in the purification liquid should also change accordingly, so as to achieve the purpose of a longer residence time of the exhaust gas in the reaction liquid, so that the exhaust gas can fully react with the purification liquid and improve the purification rate of non-methane total hydrocarbons in the exhaust gas.

[0066] Specifically, when the exhaust gas injection velocity at the pressure relief port 401 increases, the pressure in the air guide pipe 2, the connecting sleeve 3, and the support arm 4 also increases. At the same time, the pressure in the branch pipe 5 connected to the air guide pipe 2 also increases. Under the action of this pressure, the sealing plug 6 will be displaced within the branch pipe 5, compressing the cylindrical spring 8 and causing the connecting shaft 7 to move towards the outside of the branch pipe 5. Simultaneously, the connecting shaft 7 will drive the slider 9 to move away from the air guide pipe 2 along the length of the slide groove 1001. The slider 9 is connected to the connecting sleeve 3 via the traction rod 11, so that when the slider 9 moves away from the air guide pipe 2, the traction rod 11... The guide rod 11 can drive the connecting sleeve 3 to move upward along the length of the air guide pipe 2. In this state, the high-speed exhaust gas ejected from the pressure relief port 401 can be slowed down by the purification liquid in the treatment tank 1, thereby reducing the speed of the exhaust gas. This makes the exhaust gas slower when it reaches the bottom of the treatment tank 1, and then, under the action of buoyancy, it moves upward from the bottom of the treatment tank 1. This prevents the exhaust gas from contacting the bottom of the treatment tank 1 at a high speed and thus has a faster reverse movement speed. This allows the exhaust gas to have a longer movement path in the purification liquid in the treatment tank 1, thereby obtaining a longer retention time in the purification liquid.

[0067] When the jet speed of the exhaust gas at the pressure relief port 401 slows down, the pressure in the corresponding branch pipe 5 will also decrease. At this time, the elastic force provided by the cylindrical spring 8 is greater than the force exerted by the pressure on the sealing plug 6, causing the sealing plug 6 to move in the opposite direction, so that the connecting shaft 7 drives the slider 9 to move towards the guide air pipe 2. At this time, under the action of the traction rod 11, the connecting sleeve 3, the support arm 4 and the pressure relief port 401 will move downward along the length of the guide air pipe 2. At this time, the exhaust gas is discharged from the pressure relief port 401 at a slower speed, and after being decelerated by the purification liquid, it moves upward under the action of buoyancy. This also has the effect of making the exhaust gas stay in the purification liquid for a longer time, thus avoiding the exhaust gas from being discharged from the pressure relief port 401 and then directly gushing out of the purification liquid under the action of buoyancy.

[0068] With the above settings, when the exhaust gas enters the treatment tank 1, it can directly enter the purification liquid and react with it. On the one hand, this improves the purification rate of non-methane total hydrocarbons in the exhaust gas, and on the other hand, it can achieve more effective cooling of the exhaust gas, which is convenient for subsequent treatment of the exhaust gas. At the same time, when the speed at which the exhaust gas enters the purification liquid changes, the height of the pressure relief port 401 in the purification liquid will also change accordingly. This ensures that the exhaust gas has a longer residence time in the purification liquid at the corresponding speed, thereby further improving the purification rate of non-methane total hydrocarbons and the cooling effect on the exhaust gas.

[0069] Please see Figure 3 , Figure 4 , Figure 7 The guide plate 15 is rotatably mounted on the connecting sleeve 3 and cooperates with the pressure relief port 401, which enables the gas and liquid in the treatment tank 1 to rotate.

[0070] The linkage component connects the air pressure sensing component and the guide plate 15. When the pressure inside the air pipe 2 changes, the linkage component can drive the guide plate 15 to rotate to change its deflection angle.

[0071] The linkage component includes a collar 13 slidably sleeved on the communicating sleeve 3 and a right-angle connecting arm 1101 formed at the end of the traction rod 11 away from the slider 9. A support rod 12 is rotatably mounted on the right-angle connecting arm 1101, and the support rod 12 is rotatably connected to the collar 13.

[0072] The linkage assembly also includes a traction structure connecting the collar 13 and the guide plate 15. The traction structure includes a derivative rod 1301 connected to the collar 13. A pulley 14 is rotatably mounted on one end of the derivative rod 1301 away from the collar 13.

[0073] The guide plate 15 has a hysteresis groove 1501 on the side facing the connecting sleeve 3, and the pulley 14 can roll in the hysteresis groove 1501.

[0074] When the exhaust gas is ejected from the pressure relief port 401, it acts on the guide plate 15 and, guided by the guide plate 15, causes the exhaust gas to move in a spiral motion in the purification liquid. On the one hand, this improves the movement path of the exhaust gas in the purification liquid and enhances the purification effect. On the other hand, the spiral motion of the exhaust gas can drive the purification liquid to rotate and generate turbulence. The generation of turbulence improves the heat exchange effect between the exhaust gas and the purification liquid, making the cooling effect of the purification liquid on the exhaust gas more significant.

[0075] It should be noted that, considering the influence of the deflector 15 on the velocity of the exhaust gas injected from the pressure relief port 401, the angle of the deflector 15 should be variable. Specifically, if the deflector 15 maintains a predetermined angle (approaching 45°), when the exhaust gas is injected from the pressure relief port 401 at a relatively slow velocity, it will not significantly affect the exhaust gas's path. In this case, the exhaust gas can still undergo spiral motion under the guidance of the deflector 15, and even if the exhaust gas impacts the deflector 15 and moves in the opposite direction, Since the pressure relief port 401 is located at the bottom of the treatment tank 1, it can still ensure the purification and cooling effect of the purification liquid on the exhaust gas. However, when the exhaust gas is ejected at a relatively high speed from the pressure relief port 401, it will have a certain impact on the movement path of the exhaust gas. At this time, most of the exhaust gas will move in a spiral motion, and a very small part will hit the guide plate 15 and move in the opposite direction. In this state, the pressure relief port 401 and the guide plate 15 are at a relatively high height in the purification liquid, and the exhaust gas moving in the opposite direction will directly flow out of the purification liquid without being completely purified and cooled.

[0076] Based on the above considerations, in this embodiment, when the exhaust gas is ejected from the pressure relief port 401 at a relatively high speed, the slider 9 will move away from the air guide pipe 2. At the same time, while the traction rod 11 drives the connecting sleeve 3 to move upward, it will deflect itself, causing the right-angle connecting arm 1101 integrally formed with it to deflect downward. The right-angle connecting arm 1101 is connected to the collar 13 through the support rod 12, causing the collar 13 to move downward. It will also drive the pulley 14 to move downward through the derivative rod 1301. At the same time, with the cooperation of the pulley 14 and the hysteresis groove 1501, the angle of the guide plate 15 will increase (deflect towards the vertical direction), so that when the high-speed exhaust gas hits the guide plate 15, the angle of the reverse movement will be more horizontal, preventing the exhaust gas from directly gushing out of the purification liquid. At the same time, in this state, although the lateral force generated by the exhaust gas acting on the guide plate 15 is small, it can drive the purification liquid to make circular motion in the treatment tank 1.

[0077] When the exhaust gas is ejected slowly from the pressure relief port 401, the guide plate 15 will deflect in the opposite direction, causing it to tilt at 45°. At this time, the lateral force generated by the exhaust gas acting on the guide plate 15 is greater, which can drive the purified liquid to make circular motion in the treatment tank 1.

[0078] With the above settings, the exhaust gas ejected from the pressure relief port 401 will undergo a spiral motion under the action of the guide plate 15, thereby further improving the movement path of the exhaust gas in the treatment tank 1, so that the exhaust gas can be better purified and cooled. At the same time, driven by the exhaust gas, the purification liquid can rotate and generate turbulence. The generation of turbulence improves the heat exchange effect between the exhaust gas and the purification liquid, making the cooling effect of the purification liquid on the exhaust gas more significant. Moreover, the angle of the guide plate 15 is linked to the jet speed of the exhaust gas, which has the effect of preventing the exhaust gas from directly gushing out of the purification liquid.

[0079] It should also be noted that when the purified liquid makes a circular motion, its action on the support arm 4 and the guide plate 15 will cause the connecting sleeve 3 and the collar 13 to move axially, which can easily cause the traction rod 11 and the support rod 12 to generate torsional force. In order to avoid this phenomenon, strip-shaped protrusions can be provided on the outer surface of the air guide pipe 2 and the connecting sleeve 3, and strip-shaped grooves can be provided on the inner surface of the connecting sleeve 3 and the collar 13. The strip-shaped protrusions and the strip-shaped grooves slide together to avoid the connecting sleeve 3 and the collar 13 from moving axially.

[0080] Please see Figure 2 , Figures 8-10 The exhaust gas treatment device further includes:

[0081] The outlet 101 and the inlet structure are connected to the treatment tank 1, and the inlet structure can control the speed at which the purified liquid enters the treatment tank 1;

[0082] The inlet structure includes an inlet 21 communicating with the processing tank 1. A rotary connector 20 is slidably and sealed on the inlet 21. The rotary connector 20 is connected to the transmission assembly, and an extension interface 22 is rotatably and sealed at one end of the rotary connector 20 away from the inlet 21.

[0083] The inlet 21 and the end opposite to the rotary connector 20 are provided with a right-angled arc-shaped through groove 23 that is adapted to each other;

[0084] The transmission assembly connected to the slider 9 and the rotary connector 20 can drive the guide structure to move when the slider 9 moves. The transmission assembly includes a horizontal shaft 16 connected to the slider 9. A drive rod 17 is connected to one end of the horizontal shaft 16 away from the slider 9. A spiral groove 1701 is provided on the outer surface of the drive rod 17 along its length direction.

[0085] The transmission assembly also includes a follower sleeve 18 rotatably connected to the processing tank 1. The follower sleeve 18 is connected to the rotating connector 20 via a belt 19, and a convex shaft 1801 that can slide within the spiral groove 1701 is formed inside the follower sleeve 18.

[0086] In use, the extension port 22 and the outlet port 101 are connected to the external equipment via pipeline so that the purification liquid can enter the treatment tank 1 through the extension port 22 and flow out of the treatment tank 1 through the outlet port 101 to exchange heat with the exhaust gas entering the purification liquid, thereby achieving the cooling effect.

[0087] When the pressure inside the air guide pipe 2 increases, the velocity and volume of the exhaust gas entering the purification liquid will also increase accordingly. At this time, the slider 9 will move away from the air guide pipe 2 along the length of the slide groove 1001. The slider 9 drives the drive rod 17 to move through the horizontal shaft 16. At this time, the drive rod 17 will drive the follower sleeve 18 to rotate under the cooperation of the spiral groove 1701 and the convex shaft 1801. The follower sleeve 18 will drive the rotating connector 20 to rotate through the belt 19. At this time, the overlapping area of ​​the right-angle arc-shaped through groove 23 on the rotating connector 20 and the right-angle arc-shaped through groove 23 on the inlet 21 will increase, thereby increasing the amount of purification liquid entering the treatment tank 1. This realizes the mechanical linkage between the exhaust gas inflow and the purification liquid inflow, which can ensure the purification effect of the exhaust gas on the one hand and the cooling effect of the exhaust gas on the other.

[0088] With the above settings, as the speed and volume of the exhaust gas entering the purification fluid change, the amount of purification fluid entering the treatment tank 1 will also change accordingly, thus achieving automatic matching between the two. This ensures that the purification fluid can be mixed with the exhaust gas in a predetermined ratio, so that the predetermined amount of purification fluid has both good purification and cooling effects.

[0089] As an embodiment of the present invention, a method for regenerating rubber from waste tires using the aforementioned desulfurization treatment equipment is also proposed, comprising the following steps:

[0090] Step 1: Place the cleaned waste tires into the crushing device to break them into granules, and use a dust removal device to remove the dust generated during the crushing process.

[0091] Step 2: Pour the waste tire pellets into the screening equipment to separate the tire cord fibers, steel wires, etc. from the waste tire pellets;

[0092] Step 3: Screen the waste tire particles to separate out those that do not meet the particle size requirements and then crush them again.

[0093] Step 4: Pour the sieved waste tire particles into the desulfurization device, and at the same time add a predetermined proportion of softener, activator, and water into the desulfurization device and mix them. Then, through heating, pressurization, oxidation, etc., the network structure of its molecules is destroyed, so that the waste tire particles change from an elastic state to a plastic state.
