Description

Technical Field

[0001] The present invention belongs to the technical field of waste heat recycling, and specifically relates to a device for recycling waste heat from the cracked waste gas of waste tires. Background Art

[0002] With the gradual improvement of people's living standards and the rapid development of the logistics industry, the ownership of private cars and the number of trucks in China have been increasing year by year. The increase in the number of vehicles has driven economic development. At the same time, the consumption and wear of automobile tires have also generated a lot of garbage - waste tires.

[0003] The cracking of waste tires is a resource treatment process that decomposes waste tires into high-value products through thermochemical conversion technology. The core is to use high temperature (usually 400 - 800 °C) in an anaerobic or low-oxygen environment to cause the high-molecular organic matter (such as rubber) in the tires to undergo chain scission and recombination, generating products such as fuel oil, carbon black, steel wire, and combustible gas.

[0004] During the cracking process of waste tires, waste gas is generated. Traditional waste heat recovery and reuse devices for waste gas often surround the waste gas pipeline around the water tank, allowing the waste heat of the waste gas to be transferred into the water tank to heat the water in the water tank, thereby achieving the effect of waste heat recovery of the waste gas.

[0005] However, most of the water in the water tank is in a static state during the heating process and does not have fluidity, which will cause the water source near the side wall of the tank to be hotter than the water source at the center position of the tank. Summary of the Invention

[0006] To solve the problem of difficult and rapid uniform heating of the water source proposed in the above background art, the present invention provides a device for recycling waste heat from the cracked waste gas of waste tires.

The rectangular plate has a bent channel inside. On the upper surface of the rectangular plate, a first waste gas pipe and a second waste gas pipe that communicate with the bent channel are fixed. The side wall of the water tank is penetrated by a third waste gas pipe and a fourth waste gas pipe. A first hose is fixedly installed between the third waste gas pipe and the second waste gas pipe, and a second hose is fixedly installed between the fourth waste gas pipe and the first waste gas pipe.

[0014] Preferably, a number of equally spaced outer pipes surround the surface of the water tank. A flexible pipe III is fixedly installed between two adjacent outer pipes up and down.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figures 1 to 4 shown, the present invention provides a device for recycling and reusing the waste heat of waste tire cracking exhaust gas, including a water tank 1 and a rectangular plate 21 located inside the water tank 1. The rectangular plate 21 has a bent channel 22 inside. The upper surface of the rectangular plate 21 is fixed with a waste gas pipe 1 23 and a waste gas pipe 2 24 that communicate with the bent channel 22. The side wall of the water tank 1 is penetrated by a waste gas pipe 3 25 and a waste gas pipe 4 26. A hose 1 is fixedly installed between the waste gas pipe 3 25 and the waste gas pipe 2 24, and a hose 2 is fixedly installed between the waste gas pipe 4 26 and the waste gas pipe 1 23.

[0023] Among them, the hose 1 and the hose 2 are not shown in the figure. By setting the hose 1 and the hose 2, it is convenient for the subsequent up and down movement and rotation of the rectangular plate 21; The waste gas enters the bent channel 22 along the waste gas pipe three 25, the hose one, and the waste gas pipe two 24, and then exits through the waste gas pipe one 23, the hose two, and the waste gas pipe four 26; One ends of the waste gas pipe three 25 and the waste gas pipe four 26 located outside the water tank 1 are both connected to external pipes.

[0024] A lifting mechanism for driving the rectangular plate 21 to move vertically and a conveying mechanism for driving the rectangular plate 21 to rotate are arranged in the water tank 1.

[0025] By setting the lifting mechanism, the rectangular plate 21 can be driven to move up and down in the water tank 1, so that the rectangular plate 21 moves from above the water surface to below the water surface, so that the residual temperature of the waste gas inside the rectangular plate 21 can heat the water to achieve the purpose of waste heat recovery; Secondly, the rectangular plate 21 can move up and down in the water, creating water waves in the water tank 1, so that the water in the water tank 1 can be in a flowing state, and the water in the water tank 1 can evenly absorb the waste heat of the waste gas, making the waste heat of the waste gas fully play its role.

[0026] By setting the conveying mechanism, the rectangular plate 21 is driven to flip above the water surface, so that the rectangular plate 21 acts as a piston plate to complete the conveying work of the water source in the water tank 1, eliminating the need for an external water pump and effectively improving the overall energy-saving effect of the device.

[0027] Such as Figure 2 and Figure 5 As shown, the lifting mechanism includes a driving rod 31 rotatably connected to the inner wall of the water tank 1 and driven by an external motor. A support frame 33 is integrally formed on the side wall of the rectangular plate 21. Two L-shaped plates 34 are integrally formed on the surface of the support frame 33. The free end of the driving rod 31 is rotatably connected to a linkage rod 32, and the end of the linkage rod 32 away from the driving rod 31 is rotatably connected between the two L-shaped plates 34.

[0028] Such as Figure 5 、 Figure 6 and Figure 7 As shown, sliding columns one 35 and sliding columns two 36 are fixedly connected to both sides of the support frame 33 away from each other and are distributed up and down. The two sliding columns one 35 are on the same horizontal line, and the two sliding columns two 36 are on the same horizontal line. Vertical grooves 37 for the sliding columns one 35 and the sliding columns two 36 to slide up and down are provided on the inner wall of the water tank 1.

[0029] Among them, the sliding columns one 35 and the sliding columns two 36 are slidably connected in the vertical grooves 37, so that the vertical grooves 37 can limit the moving range of the support frame 33, the L-shaped plates 34, and the rectangular plate 21; When the active rod 31 rotates driven by an external motor, it can push and pull the L-shaped plate 34, the support frame 33, and the rectangular plate 21 through the linkage rod 32, causing the rectangular plate 21 to move vertically.

[0030] As Figure 7 and Figure 8 shown, the conveying mechanism includes an arc-shaped groove 41 formed on the inner wall of the water tank 1 and communicating with the vertical groove 37. The connection between the arc-shaped groove 41 and the vertical groove 37 is located at the midpoint of the vertical groove 37. The position where the upper end of the vertical groove 37 is located is the same as the position where the center of the arc-shaped groove 41 is located. An auxiliary plate 42 is fixedly connected to the side wall of the water tank 1.

[0031] Among them, when the first sliding column 35 moves to the upper end of the vertical groove 37, the support frame 33 on the side wall of the rectangular plate 21 is in a tightly attached state with the auxiliary plate 42, thereby dividing the water tank 1 into upper and lower spaces, and the space below the rectangular plate 21 is in a sealed state.

[0032] As Figure 7 and Figure 8 shown, an arc-shaped limiting block 43 is integrally formed at one corner above the water tank 1. The arc-shaped limiting block 43 is located on the side away from the auxiliary plate 42. The center position of the arc-shaped side of the arc-shaped limiting block 43 is at the same point as the center position of the arc-shaped groove 41.

[0033] When the first sliding column 35 is located at the upper end of the vertical groove 37 and the second sliding column 36 is located at the connection between the vertical groove 37 and the arc-shaped groove 41, at this time, if the active rod 31 and the linkage rod 32 continue to give a thrust to the L-shaped plate 34, the support frame 33, and the rectangular plate 21, the rectangular plate 21 can rotate around the first sliding column 35 as the axis; At the same time, the support frame 33 on the side wall of the rectangular plate 21 is in a tightly attached state with the auxiliary plate 42, and the other side of the rectangular plate 21 is also in a tightly attached state with the arc-shaped limiting block 43; Then, during the process of the rectangular plate 21 rotating back and forth around the first sliding column 35 as the axis, the space below the rectangular plate 21 is always in a sealed state.

[0034] As Figure 8 shown, an air outlet pipe 44 and an air inlet pipe 45 that communicate with the inside of the water tank 1 penetrate through the side wall of the water tank 1. A one-way air outlet valve 46 is installed on the air outlet pipe 44, and a one-way air inlet valve 47 is installed on the air inlet pipe 45. The horizontal positions of the air outlet pipe 44 and the air inlet pipe 45 are lower than the horizontal position of the auxiliary plate 42.

[0035] As Figure 9 shown, a water outlet pipe 48 and a water inlet pipe 49 that communicate with the inside of the water tank 1 are fixed to the side wall of the water tank 1. A one-way water inlet valve 410 is installed on the water inlet pipe 49, and a one-way water outlet valve 411 is installed on the water outlet pipe 48. The water inlet pipe 49 is connected to an external water source to be heated.

[0036] When it is necessary to inhale external water into the water tank 1, the rectangular plate 21 is driven to swing back and forth around the sliding column 35, and the one-way air outlet valve 46 and the one-way water inlet valve 410 are opened. As the rectangular plate 21 swings, the external water source can be inhaled into the water tank 1 through the water inlet pipe 49 and the one-way water inlet valve 410, and at the same time, the gas in the water tank 1 is discharged through the air outlet pipe 44 and the one-way air outlet valve 46; When it is necessary to discharge the heated water from the water tank 1, the rectangular plate 21 is driven to swing back and forth around the sliding column 35, and the one-way water outlet valve 411 and the one-way air inlet valve 47 are opened. As the rectangular plate 21 swings, the water in the water tank 1 can be discharged through the water outlet pipe 48 and the one-way water outlet valve 411, and at the same time, external gas is inhaled into the water tank 1 through the air inlet pipe 45 and the one-way air inlet valve 47.

[0037] As Figure 1 shown, a number of equally spaced external pipes 5 are arranged around the surface of the water tank 1. A third flexible pipe 6 is fixedly installed between two adjacent upper and lower external pipes 5. The free ends of the lowermost external pipe 5 and the uppermost external pipe 5 are connected to the external pipe. The lowermost external pipe 5 is fixedly connected to the water tank 1. An adjusting mechanism for adjusting the distance between the external pipes 5 is provided in the water tank 1.

[0038] Adopting the above scheme, allowing a part of the waste gas to enter the external pipe 5 and perform heating work outside the water tank 1 can effectively improve the heating efficiency of the water source in the water tank 1 and give full play to the waste heat of the waste gas; When the amount of waste gas is small, the amount of water that can be heated is correspondingly reduced, and the water level in the water tank 1 will be relatively low. The rectangular plate 21 cannot move below the water surface for heating work, and only heating work can be carried out through the external pipe 5; By providing an adjusting mechanism, the distance between multiple external pipes 5 can be adjusted. When the water level is relatively low, the external pipes 5 are driven to move downward so that the overall height of the multiple external pipes 5 is consistent with the height of the water level, allowing the waste gas to give full play to its waste heat.

[0039] As Figure 6 and Figure 10 shown, the adjusting mechanism includes a threaded rod 61 rotatably connected to the top surface of the inner wall of the water tank 1, and a gear 62 coaxially fixed below the threaded rod 61. An internally threaded sleeve 63 is sleeved on the threaded rod 61 and is threadedly connected thereto. Both sides of the internally threaded sleeve 63 away from each other are fixedly connected with connecting rods 64. The free ends of the two connecting rods 64 pass through the water tank 1 and are fixed to the uppermost external pipe 5. The connecting rods 64 and the water tank 1 are telescopically connected.

[0040] As Figure 8 and Figure 9As shown, an arc-shaped rack 65 is fixedly connected to the upper surface of the rectangular plate 21. Four long rods 66 are arranged between every two outer pipes 5. The ends of the four long rods 66 are rotatably connected to form a rhombus structure. Two of the long rods 66 are rotatably connected to the lower outer pipe 5, and the other two long rods 66 are rotatably connected to the upper outer pipe 5.

[0041] Among them, the arc-shaped rack 65 can be meshed with the gear 62.

[0042] The working principle of the present invention: Let a part of the waste gas enter the bent channel 22 along the waste gas pipe three 25, the hose one and the waste gas pipe two 24, and then go out through the waste gas pipe one 23, the hose two and the waste gas pipe four 26; Another part of the waste gas enters the outer pipe 5 and is heated outside the water tank 1; When the driving rod 31 is driven to rotate by an external motor, it can push and pull the L plate 34, the support frame 33 and the rectangular plate 21 through the linkage rod 32, so that the rectangular plate 21 moves along the vertical direction. When the rectangular plate 21 moves from above the water surface to below the water surface, the residual temperature of the waste gas inside the rectangular plate 21 can heat the water, achieving the purpose of waste heat recovery; Secondly, the rectangular plate 21 can move up and down within a small range in the water, creating water waves in the water tank 1, so that the water in the water tank 1 can be in a flowing state. Then the water in the water tank 1 can evenly absorb the waste heat of the waste gas, making the waste heat of the waste gas fully play its role; During use, the water level in the water tank 1 should be kept below the auxiliary plate 42; When the first sliding column 35 is located at the upper end of the vertical groove 37 and the second sliding column 36 is located at the connection of the vertical groove 37 and the arc-shaped groove 41. At this time, if the driving rod 31 and the linkage rod 32 continue to give a thrust to the L plate 34, the support frame 33 and the rectangular plate 21, the rectangular plate 21 can rotate around the first sliding column 35 as the axis; At the same time, the support frame 33 on the side wall of the rectangular plate 21 is in close contact with the auxiliary plate 42, and the other side of the rectangular plate 21 is also in close contact with the arc-shaped limiting block 43; Then, during the process of the rectangular plate 21 rotating back and forth around the first sliding column 35 as the axis, the space below the rectangular plate 21 is always in a sealed state; When it is necessary to inhale external water source into the water tank 1, drive the rectangular plate 21 to swing back and forth around the first sliding column 35, and open the one-way air outlet valve 46 and the one-way water inlet valve 410. As the rectangular plate 21 swings, the external water source can be inhaled into the water tank 1 through the water inlet pipe 49 and the one-way water inlet valve 410, and at the same time, the gas in the water tank 1 can be discharged through the air outlet pipe 44 and the one-way air outlet valve 46; When it is necessary to drain the heated water from the water tank 1, the rectangular plate 21 is driven to swing back and forth with the sliding column 35 as the axis, and the one-way water outlet valve 411 and the one-way air inlet valve 47 are opened. As the rectangular plate 21 swings, the water in the water tank 1 can be drained through the water outlet pipe 48 and the one-way water outlet valve 411, and at the same time, external gas is inhaled into the water tank 1 through the air inlet pipe 45 and the one-way air inlet valve 47; When the amount of exhaust gas is small, the amount of water that can be heated needs to be reduced accordingly, and the water level in the water tank 1 will be relatively low. When the rectangular plate 21 cannot move below the water surface for heating work and can only perform heating work through the outer pipe 5, the rectangular plate 21 is driven to rotate with the sliding column 35 as the axis, driving the arc-shaped rack 65 fixed on the surface of the rectangular plate 21 to rotate accordingly, so that the arc-shaped rack 65 gradually meshes with the gear 62, driving the gear 62 to rotate. The gear 62 can drive the threaded rod 61 fixed coaxially with it to rotate accordingly. The threaded rod 61 can drive the internally threaded sleeve 63 to move downward. The internally threaded sleeve 63 can drive the outer pipe 5 to move downward through the connecting rod 64. Since four long rods 66 are provided between every two outer pipes 5, all the outer pipes 5 will move downward simultaneously and maintain an equally spaced distribution state; Finally, the overall height of the multiple outer pipes 5 is adapted to the water level, enabling the exhaust gas in the outer pipes 5 to fully utilize the waste heat.
