Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a desulfurization device for non-condensable gas in the thermal cracking of waste rubber and plastic. Background Technique

[0002] With the development of the manufacturing industry economy, the consumption of rubber and plastic raw materials is increasing. Rubber products are indispensable in all walks of life, from large aircraft, ships, and automobiles to small daily necessities. As a result, the environmental pollution caused by waste garbage is becoming increasingly serious. Therefore, it is urgent to control the "black pollution" caused by solid materials such as waste tires and waste plastics;

[0003] Thermal desulfurization of non-condensable gas is a technology for desulfurizing non-condensable gas generated during the thermal cracking of waste rubber and plastic. During the thermal cracking process, waste rubber and plastic break their polymer chains to generate products such as fuel oil, pyrolysis gas, crude carbon black, and steel wire under anaerobic or anoxic and appropriate temperature conditions. At the same time, non-condensable gas will also be generated. These non-condensable gases may contain sulfides, which can corrode the gas storage tank, leading to safety problems.

[0004] When the reaction is carried out, a catalyst needs to be used to improve the reaction efficiency. In the existing device, the gas flow is relatively single and only enters the inside of the treatment chamber through pipe fittings, resulting in local gas concentration, poor contact effect with the catalyst and reactants, and thus affecting the desulfurization effect. Summary of the Utility Model

[0005] The utility model discloses a desulfurization device for non-condensable gas in the thermal cracking of waste rubber and plastic, aiming to solve the technical problem that when the reaction is carried out, a catalyst needs to be used to improve the reaction efficiency. In the existing device, the gas flow is relatively single and only enters the inside of the treatment chamber through pipe fittings, resulting in local gas concentration, poor contact effect with the catalyst and reactants, and thus affecting the desulfurization effect.

A cross bar is fixedly connected to the inner wall of the processing box, and a second bump is fixedly connected to the lower end of the cross bar.

[0009] Preferably, rectangular blocks are uniformly and fixedly connected to the outer side of the conical block;

[0022] Referring to Figures 1-4 , the waste rubber and plastic pyrolysis non-condensable gas desulfurization equipment includes a processing box 1. An exhaust pipe 6 is fixedly connected to the upper end of the processing box 1 for discharging gas. An air inlet pipe 4 is fixedly connected to the lower end of the processing box 1. A solution spraying mechanism is arranged inside the processing box 1, and a gas turbulence mechanism is arranged in the processing box 1;

[0023] The gas turbulent flow mechanism includes a motor 5 fixedly connected to the upper end of the treatment tank 1. The motor 5 is a driving mechanism. In the prior art, a rod 19 is movably connected to the lower end of the motor 5. The output end of the motor 5 drives the rod 19 to rotate. The lower end of the rod 19 is slidably connected to a rectangular rod 15. The rectangular rod 15 can move up and down inside the rod 19. At the same time, when the rod 19 rotates, it can drive the rectangular rod 15 to rotate. A spring 20 is fixedly connected to the upper end of the rectangular rod 15. The spring 20 is fixedly connected to the inner wall of the rod 19. A conical block 8 is fixedly connected to the lower end of the rectangular rod 15. First convex blocks 18 are evenly and fixedly connected to the upper end of the conical block 8. A cross bar 16 is fixedly connected to the inner wall of the treatment tank 1. A second convex block 17 is fixedly connected to the lower end of the cross bar 16. When the first convex block 18 contacts the second convex block 17, the first convex block 18 moves downward, thereby driving the conical block 8 to move downward. The first convex block 18 and the second convex block 17 are misaligned. Under the action of the spring 20, the rectangular rod 15 resets;

[0024] During operation, the motor 5 is started. The motor 5 drives the rod 19 to rotate. The rod 19 rotates to drive the rectangular rod 15 to rotate. The rectangular rod 15 rotates to drive the conical block 8 to rotate, generating a rotating air flow inside. At the same time, when the conical block 8 moves, it drives the upper first convex blocks 18 to rotate. The first convex blocks 18 are disengaged from the second convex blocks 17, causing the first convex blocks 18 to drive the conical block 8 to move downward. When the first convex blocks 18 and the second convex blocks 17 are misaligned, at this time, the conical block 8 resets under the action of the spring 20, so that the conical block 8 can continuously move up and down. In this way, through the motor 5, the conical block 8 can rotate while continuously moving up and down, making the air flow entering the treatment tank 1 more turbulent. At the same time, the shape of the conical block 8 can exert an appropriate rebounding effect on gas molecules, making the waste gas more evenly distributed, enabling better contact between the waste gas and the solution, and improving the waste gas treatment effect.

[0025] Refer to Figure 2 , rectangular blocks 9 are evenly and fixedly connected to the outer side of the conical block 8. By providing the rectangular blocks 9, the effect of driving the air flow when the conical block 8 rotates is better.

[0026] Refer to Figure 1 and Figure 3 , connecting rods 11 are evenly and fixedly connected to the upper inner wall of the treatment tank 1. The connecting rods 11 are for supporting. A ring 12 is fixedly connected to the lower end of the connecting rods 11. A liquid shell 13 is rotatably connected to the inner wall of the ring 12. An atomizing head 14 is fixedly connected to the lower end of the liquid shell 13 to atomize and spray the waste gas solution. The lower end of the liquid shell 13 is fixedly connected to the upper end of the rod 19. A liquid inlet pipe 7 is fixedly connected to the left side of the ring 12;

[0027] The output end of the motor 5 drives the liquid shell 13 to rotate, making the solution more evenly sprayed during spraying and improving the contact effect with the waste gas.

[0028] Referring to Figure 1 , a slant block 10 is fixedly connected to the lower end inside the processing box 1, a U-shaped pipe fitting 2 is fixedly connected to the right side of the processing box 1, the upper end of the U-shaped pipe fitting 2 is fixedly connected to the right side of the circular ring 12, and a liquid pump 3 is fixedly connected to the pipe wall of the U-shaped pipe fitting 2. The solution is transported to the upper end again by the arranged liquid pump 3 and sprayed out from the liquid shell 13, thereby saving the use of the processing liquid.

[0029] Referring to Figure 2 , the conical block 8 is hollow, which improves the gas rebound effect.

[0030] Working principle: When working, start the motor 5. The motor 5 drives the rod 19 to rotate. The rotation of the rod 19 drives the rectangular rod 15 to rotate. The rotation of the rectangular rod 15 drives the conical block 8 to rotate, generating a rotating air flow inside. At the same time, when the conical block 8 moves, it drives the first convex block 18 at the upper end to rotate. The first convex block 18 disengages from the second convex block 17, causing the first convex block 18 to drive the conical block 8 to move downward. When the first convex block 18 is misaligned with the second convex block 17, at this time, the conical block 8 is reset under the action of the spring 20, so that the conical block 8 can continuously move up and down. In this way, through the motor 5, the conical block 8 can rotate while continuously moving up and down, making the air flow entering the inside of the processing box 1 more disordered. At the same time, the shape of the conical block 8 can exert an appropriate rebounding effect on gas molecules, so that the waste gas can be more evenly dispersed, making the waste gas contact the solution better and improving the waste gas treatment effect.
