Description

Technical Field

[0001] This utility model relates to the field of calcined coke emission treatment, and in particular to a low-sulfur emission treatment device for calcined coke. Background Technology

[0002] Low-sulfur calcined coke is a key raw material for electrolytic aluminum and high-end graphite electrodes. Relevant information can be analyzed from three aspects: First, in terms of raw materials, it is based on low-sulfur petroleum coke, which is produced from heavy crude oil residue through delayed coking. The sulfur content needs to be controlled at a low level, with even stricter requirements in high-end applications. The low-sulfur characteristic relies on both low-sulfur crude oil and crude oil pretreatment processes. Second, in terms of process, the core of preparation is the high-temperature calcination of low-sulfur petroleum coke. This process requires isolation from air, often achieved using a closed calcination furnace with inert gas or controlled negative pressure. Simultaneously, precise temperature control prevents carbon loss and sulfur escape, and parameters are adjusted according to the particle size and moisture content of the raw materials to ensure stable calcination. Third, in terms of performance, after calcination removes moisture and volatile matter, the density, conductivity, and mechanical strength of the low-sulfur calcined coke are improved, its oxidation resistance is enhanced, and its resistivity is significantly reduced, enabling energy conservation and emission reduction in downstream industries.

[0003] Most existing low-sulfur emission treatment devices for calcined coke often require a large amount of water during the flushing process, resulting in a waste of water resources. Therefore, we propose a low-sulfur emission treatment device for calcined coke to solve the above problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5This utility model provides a technical solution for a low-sulfur emission treatment device for calcined coke, including a base plate 1. A sedimentation tank 2 is fixedly connected to the upper surface of the base plate 1 by multiple support legs. A sludge collection tank 3 is connected to the bottom surface of the sedimentation tank 2. A first motor 4 is installed on the bottom surface of the sludge collection tank 3. The output end of the first motor 4 passes through the sludge collection tank 3 and is connected to a rotating rod 5. Multiple rotating plates 6 are fixedly connected to the outer surface of the rotating rod 5. Multiple fixing plates 8 are fixedly connected to the inner wall of the sedimentation tank 2. A central tube 9 is connected to the side of the multiple fixing plates 8 away from the sedimentation tank 2. Multiple support columns 10 are fixedly connected to the bottom end of the central tube 9. A reflector plate 11 is connected to the bottom surface of the multiple support columns 10. A baffle 7 is connected to the inner wall of the sedimentation tank 2.

[0018] like Figure 1 and Figure 4 As shown, a support frame 12 is fixedly connected to the upper surface of the base plate 1. A controller 13 is installed on the outer surface of the support frame 12. A mixing tank 14 is fixedly connected inside the support frame 12. A feed pipe 15 is connected to the upper surface of the mixing tank 14. A feeding pipe 16 is connected to the upper surface of the mixing tank 14. A first valve 17 is installed on the outer surface of the feeding pipe 16. A second motor 18 is installed on the upper surface of the mixing tank 14. The output end of the second motor 18 passes through the mixing tank 14 and is connected to a round rod 19. The outer surface of the round rod 19 is fixedly connected to the controller 13. Multiple stirring blades 20 are fixedly connected to the cylindrical rod 19, and multiple scrapers 21 are fixedly connected to the outer surface of the cylindrical rod 19. The second motor 18 is started by the controller 13, and its output end drives the cylindrical rod 19 to rotate. On the one hand, the stirring blades 20 on the outer surface of the cylindrical rod 19 rotate at high speed, so that the calcined coke and the desulfurization agent can fully contact and mix evenly, ensuring that the sulfur in the calcined coke reacts efficiently with the agent. On the other hand, the synchronously rotating scrapers 21 can scrape off the material attached to the inner wall of the mixing tank 14, avoiding raw material waste and tank wall scaling, and ensuring reaction efficiency.

[0019] like Figure 5 and Figure 1As shown, the bottom of the mixing tank 14 is connected to a discharge pipe 22, and a second valve 23 is installed on the outer surface of the discharge pipe 22. After the desulfurization reaction is completed, the second valve 23 on the discharge pipe 22 at the bottom of the mixing tank 14 is opened, and the mixed material enters the spiral dewatering module 24 through the discharge pipe 22. The end of the discharge pipe 22 away from the mixing tank 14 is connected to the spiral dewatering module 24. The bottom of the spiral dewatering module 24 is connected to a water storage tank 25, and a collection box 32 is set below the spiral dewatering module 24. The spiral dewatering module 24 can be a spiral dewatering machine, which achieves solid-liquid separation through the spiral extrusion principle. The separated low-sulfur calcined coke falls into the collection box 32 below. 2. As a temporary storage of finished products, the separated sulfur-containing wastewater flows into the water storage tank 25 through the guide structure on the bottom of the module to prepare for subsequent water circulation. The outer surface of the water storage tank 25 is equipped with a first pump body 26. The input end of the first pump body 26 passes through the water storage tank 25 and extends into the interior of the water storage tank 25. The output end of the first pump body 26 is connected to a water delivery pipe 27. The end of the water delivery pipe 27 away from the first pump body 26 passes through the sedimentation tank 2 and the central pipe 9 in sequence and extends into the interior of the central pipe 9. The first pump body 26 is started by the controller 13, and its input end extends into the water tank to extract the sulfur-containing wastewater, which is then transported to the central pipe 9 in the sedimentation tank 2 through the water delivery pipe 27.

[0020] like Figure 3 and Figure 5 As shown, a connecting pipe 28 is connected to the outer surface of the sedimentation tank 2. The end of the connecting pipe 28 away from the sedimentation tank 2 is connected to a water storage tank 29. A second pump body 30 is installed on the outer surface of the water storage tank 29. The input end of the second pump body 30 passes through the water storage tank 29 and extends into the interior of the water storage tank 29. The output end of the second pump body 30 is connected to a transmission pipe 31. The end of the transmission pipe 31 away from the second pump body 30 is connected to the top of the feeding pipe 16. The second pump body 30 on the outer surface of the water storage tank 29 is started by the controller 13. Its input end extends into the tank to draw clean water, which is then transported back to the feeding pipe 16 through the transmission pipe 31 and reused for dilution of desulfurization agents or material mixing in the mixing tank 14.

[0021] like Figure 1 As shown, a third pump body 33 is installed on the upper surface of the base plate 1. The input end of the third pump body 33 is connected to a sludge suction pipe 34. The end of the sludge suction pipe 34 away from the third pump body 33 is connected to the outer surface of the sludge collection tank 3. A third valve 35 is installed on the outer surface of the sludge suction pipe 34. The third pump body 33 is started by the controller 13, and the third valve 35 on the sludge suction pipe 34 is opened. The impurities in the tank are then drawn to the external treatment equipment through the sludge suction pipe 34 to achieve centralized cleaning of impurities, avoid impurities clogging the sedimentation system, and ensure the continuous and stable operation of the device.

[0022] The working principle of this utility model is as follows: wastewater is dispersed by the central pipe 9 and sprayed into the sedimentation tank 2. The baffle 7 on the inner wall of the sedimentation tank 2 cooperates with the fixed plate 8 fixed on the inner wall to slow down the water flow speed. At the same time, the reflector 11 connected to the bottom of the central pipe 9 through the support column 10 guides the water flow to spread evenly, so that the impurities in the wastewater are fully suspended and initially settled. The baffle 7 on the inner wall of the sedimentation tank 2 is an "overflow trough structure". After the wastewater has settled, the clean water can overflow through the outflow trough of the baffle 7 and flow precisely to the subsequent pipeline. The first motor 4 is started. Its output end passes through the sludge collection tank 3 and drives the rotating rod 5 to rotate. The rotating plate 6 on the outer surface of the rotating rod 5 rotates synchronously, accelerating the sedimentation of impurities in the wastewater. The settled impurities finally fall into the sludge collection tank 3.

[0023] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
