Description

Technical Field

[0001] The present application relates to the field of gas-solid separation technology, and specifically to a tail gas-solid separation device for a sodium sulfate pyrolysis furnace. Background Art

[0002] In the production of new energy materials, lithium carbonate and sodium carbonate react with sulfuric acid to produce a low-concentration mixed solution of lithium sulfate and sodium sulfate. Most of the sodium sulfate can be separated through evaporation, concentration, and crystallization. Sodium sulfate exists in large quantities as a byproduct, but the separated sodium sulfate contains a large amount of impurities and water of crystallization. It needs to be dried and pyrolyzed before it can be used as an industrial raw material. Therefore, the material needs to be processed in a pyrolysis furnace, which generates a large amount of waste gas after processing. At this time, it needs to be purified by a gas-solid separation device.

[0003] For example, the patent with publication number CN220728955U specifically discloses a multi-chamber thermal storage oxidation furnace. Through two branch pipes arranged inside the spray tower, the exhaust gas after preliminary treatment can be repeatedly sprayed to prevent the flow rate or flow from being too large, resulting in short processing time and incomplete treatment. The two swirl plates can rotate the exhaust gas upward, so that the liquid in the spray pipe is sprayed into droplets, which has a larger contact area between the gas and the liquid, thereby improving the purification effect.

[0004] In the above patent, the device provides two sets of branch pipes and swirl plates to increase the contact area between gas and liquid, thereby improving the purification effect. However, since the spray tower needs to harmlessly treat a large amount of exhaust gas, the packing layer on the top of the filter plate will absorb a large amount of harmful substances when the exhaust gas is purified. After long-term use, the packing layer may be wrapped by harmful substances and cause blockage. At this time, the packing needs to be replaced. However, since the various filter plates inside the spray tower are fixedly installed, the entire work may need to be stopped when the packing needs to be replaced, thereby affecting production. Therefore, it is necessary to provide a tail gas-solid separation device for a sodium sulfate pyrolysis furnace that can quickly replace the packing to solve the above problem.

[0041] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0042] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0043] Example 1: This example specifically describes the basic structure and working principle of the tail gas-solid separation device for a sodium sulfate pyrolysis furnace, specifically:

[0044] like Figure 1-Figure 2 As shown, the present application provides a tail gas-solid separation device for a sodium sulfate pyrolysis furnace, including a pyrolysis furnace 1, which is arranged in a sodium sulfate processing plant. In the preparation process of sodium sulfate, lithium carbonate and sodium carbonate need to react with sulfuric acid to generate a low-concentration mixed solution of lithium sulfate and sodium sulfate, and most of the sodium sulfate is separated by evaporation, concentration and crystallization. At this time, the separated sodium sulfate can be subjected to high-temperature pyrolysis and purification by the pyrolysis furnace 1. By indirectly or directly heating the sodium sulfate, the sodium sulfate containing crystal water is converted into anhydrous sodium sulfate, and the tail gas containing solid particulate matter and gaseous pollutants is released at the same time, so that the solid particulate matter can be used as an industrial raw material later;

[0045] Since a large amount of tail gas is generated during the pyrolysis process of sodium sulfate, the tail gas contains a large amount of pollutants and needs to be discharged into the atmosphere after gas-solid separation. For this reason, a separation component 2 is provided on one side of the pyrolysis furnace 1. The separation component 2 is used to purify the tail gas generated by pyrolysis. The separation component 2 includes a cyclone dust collector 21, which is provided on one side of the pyrolysis furnace 1. The cyclone dust collector 21 has an air inlet 22, which is connected to the pyrolysis furnace 1. At the same time, a collection box 23 is provided at the bottom of the cyclone dust collector 21.

[0046] When the cyclone dust collector 21 is working, high-temperature exhaust gas will enter the cyclone dust collector 21 through the air inlet 22. At this time, the solid particles in the exhaust gas are thrown toward the wall of the device due to inertia, and spiral down along the cylinder wall under the action of gravity and air flow friction, and finally fall into the collection box 23 and are recovered. At the same time, an exhaust pipe 24 is also provided on one side of the cyclone dust collector 21. The high-temperature exhaust gas that has been initially recovered by the cyclone dust collector 21 will be discharged from the exhaust pipe 24.

[0047] At the same time, a spray tower 3 is also provided on one side of the cyclone dust collector 21. The spray tower 3 is used to harmlessly treat the high-temperature exhaust gas that has been initially recovered by the cyclone dust collector 21. An air inlet is provided on one side of the spray tower 3, and the air inlet is connected to the exhaust pipe 24 of the cyclone dust collector 21. At the same time, multiple groups of packing layers 4 are provided inside the spray tower 3. The packing layers 4 are used to carry packing balls. At the same time, a spray pipe 31 is fixedly installed on one side near the bottom of the spray tower 3. The spray pipe 31 has multiple groups of branch pipes 32, and the branch pipes 32 are provided inside the spray tower 3. The number of the branch pipes 32 corresponds to the number of the packing layers 4. At the same time, a spiral atomizing nozzle 33 is provided at the bottom of the branch pipe 32. The spiral atomizing nozzle 33 is used to spray alkaline absorption liquid through circulation to facilitate multi-stage absorption of residual pollutants in the exhaust gas;

[0048] At the same time, a water tank 34 is provided at the bottom of the spray tower 3, which is used to receive the sprayed mixed solution and send it to the next processing link, and an air outlet 35 is provided at the top of the spray tower 3, which is used to discharge clean air.

[0049] When the high-temperature exhaust gas enters from the bottom of the spray tower 3, it will pass through the packing layer 4 and contact and mix with the alkaline absorption liquid atomized and falling by the top spiral atomizing nozzle 33. At this time, the droplets sprayed by the spiral atomizing nozzle 33 capture the fine particles in the exhaust gas through inertial collision, interception and diffusion, so that the alkaline absorption liquid and the exhaust gas undergo a chemical reaction to generate soluble salts. The exhaust gas passes through the packing layer 4 to extend the contact time and improve the absorption efficiency. Finally, the exhaust gas passes through the top demisting layer to remove the entrained droplets and is discharged cleanly. The mixed solution will enter the water tank 34 and flow into the next treatment link.

[0050] Since the multiple groups of packing balls placed on the packing layer 4 inside the spray tower 3 are in contact with the exhaust gas and the mixed solution for a long time, impurities are easily accumulated inside the packing balls, which may affect the subsequent gas-liquid exchange. Therefore, a replacement component 5 is provided on one side of the spray tower 3. The replacement component 5 is used to quickly replace the packing balls without stopping the machine.

[0051] like Figure 2-Figure 4 As shown, the replacement component 5 includes a holding box 51 fixedly mounted on one side of the spray tower 3. The holding box 51 is sealedly connected to the spray tower 3. At the same time, multiple sets of tracks 52 are provided in the holding box 51. The tracks 52 are in groups of two, and the tracks 52 pass through the spray tower 3 and are connected to the interior of the spray tower 3. At the same time, the packing layer 4 includes a placement dish 41 for placing packing balls. The top of the placement dish 41 is open, and multiple sets of through holes (not shown in the figure) for solution to pass through are provided at the bottom. The diameter of the placement dish 41 matches the diameter of the interior of the spray tower 3. The placement dish 41 is slidably mounted on the track 52, so that it can quickly move back and forth between the spray tower 3 and the holding box 51.

[0052] In order to ensure that the placement dish 41 remains sealed during its rapid movement from the spray tower 3 to the holding box 51 and to prevent exhaust gas from escaping from the spray tower 3, a channel mechanism is provided on both sides of the spray tower 3 corresponding to the number of packing layers 4. The channel mechanism includes multiple groups of openings located on the side of the spray tower 3 close to the holding box 51, and a first connecting block 42 and a second connecting block 43 are respectively extended on both sides of the placement dish 41. The first connecting block 42 and the second connecting block 43 have the same size and are adapted to the size of the openings to seal the openings.

[0053] At the same time, a boss is provided on the side of the spray tower 3 away from the receiving box 51. A hollow receiving chamber is provided inside the boss. The size of the receiving chamber matches the size of the second connecting block 43. When the placement dish 41 is located inside the spray tower 3, the first connecting block 42 will block the opening, and the second connecting block 43 will enter the boss. At this time, the placement dish 41 is located on the purification station.

[0054] At the same time, multiple groups of first cylinders 53 are provided on the storage box 51 corresponding to the number of placement dishes 41. The first cylinders 53 are fixedly installed on the outside of the storage box 51. The output end of the first cylinder 53 passes through the storage box 51 and is fixedly connected to the first connecting block 42. When replacement is required, the placement dishes 41 are driven to move by the first cylinders 53, thereby realizing the rapid transfer of the placement dishes 41.

[0055] When the placement dish 41 is located inside the spray tower 3, the first connecting blocks 42 located on both sides of the placement dish 41 will block the opening inside the spray tower 3. When the placement dish 41 moves from the spray tower 3 to the inside of the holding box 51 under the action of the first cylinder 53, the first connecting block 42 will gradually separate from the opening. When the placement dish 41 is located inside the holding box 51, the opening will be blocked by the second connecting block 43. At this time, only a small amount of exhaust gas inside the spray tower 3 will enter the holding box 51 and will not enter the atmosphere, thereby ensuring that the exhaust gas will not leak outward during the transfer of the placement dish 41, which will help the subsequent packing ball replacement step.

[0056] like Figure 3-Figure 4 As shown, a loading assembly is provided on the top of the storage box 51, and the loading assembly includes a storage bin 6, which is used to store unused filling balls. At the same time, a discharge pipe 61 is provided at the bottom of the storage bin 6, and the discharge pipe 61 is connected to the storage bin 6. A plurality of discharge pipes 62 are provided on the discharge pipe 61 corresponding to the number of placement dishes 41. The discharge pipes 62 are used to distribute the filling balls to different placement dishes 41. Electric control valves are provided on the discharge pipes 61 and the discharge pipes 62. The control valves are uniformly controlled by a PLC operating system, so that the filling balls can be quickly discharged to the placement dishes 41.

[0057] like Figure 4-Figure 7 As shown, in order to allow the filling balls inside the placement dish 41 to be quickly discharged, a funnel-shaped discharge port 411 is provided on one side of the bottom of the placement dish 41. The setting of the discharge port 411 allows the material to be quickly discharged from the placement dish 41 without any residue, and a slide 412 is provided on the outside of the discharge port 411. A cover plate 413 is slidably mounted on the upper side of the slide 412. A block 414 is provided at the bottom of the cover plate 413. The cover plate 413 is used to block the discharge port 411, and a spring is provided between the cover plate 413 and the slide 412.

[0058] At the same time, a unloading assembly is provided at the bottom of the receiving box 51, and the unloading assembly includes a storage chamber 63, which is used to store filler balls after long-term use. A discharge pipe 64 is provided on the top of the storage chamber 63, and a plurality of discharge pipes 65 are extended outward on the discharge pipe 64 corresponding to the number of placement dishes 41. It can be understood that the discharge pipe 64 and the discharge pipe 65 are deeper in the receiving box 51 than the unloading pipe 61 and the discharge pipe 62, and a plurality of control valves are also provided on the discharge pipe 64 and the discharge pipe 65. The discharge pipe 65 is used to be connected to the discharge port 411 at the bottom of the placement dish 41, so that the placement dish 41 can quickly discharge the filler balls inside.

[0059] When the filling balls in the placement dish 41 need to be replaced, the placement dish 41 is first moved from the spray tower 3 to the unloading assembly inside the holding box 51 under the action of the first cylinder 53. When the placement dish 41 is about to reach the material replacement position, the discharge pipe 65 at the bottom will contact the block 414 on the cover plate 413, and as the placement dish 41 moves, the discharge pipe 65 will push the cover plate 413 to move on the slide 412 until it no longer blocks the discharge port 411. At this time, the discharge pipe 65 will be connected to the discharge port 411, so that the filling balls in the placement dish 41 are discharged from the discharge port 411 into the discharge pipe 65, and then collected by the storage chamber 63 and moved to the next processing link;

[0060] When the filling balls inside the placement dish 41 are completely discharged, the staff can drive the placement dish 41 to retreat by controlling the first cylinder 53. As the placement dish 41 gradually moves, the cover plate 413 will re-block the discharge port 411 under the action of the spring. When the discharge port 411 is completely closed, the placement dish 41 will reach the position of the loading assembly. At this time, the control valves on the discharge pipe 61 and the discharge pipe 62 can be opened to transport new filling balls from the storage bin 6 to the placement dish 41. When the placement dish 41 is full, the discharge is stopped, and the placement dish 41 is transported back to the spray tower 3 through the first cylinder 53, thereby completing the rapid replacement of the filling balls.

[0061] Embodiment 2: Since the filler balls inside the placement dish 41 may accumulate impurities due to long-term exhaust gas purification, multiple groups of filler balls may stick together due to the impurities, making it difficult to remove and replace them later, improvements are made in the track 52, specifically:

[0062] like Figures 8-10 As shown, multiple groups of circular bumps 7 are provided inside the track 52. The bumps 7 are made of high-strength, corrosion-resistant materials to ensure that they will not wear or deform during long-term use. The multiple groups of bumps 7 are evenly distributed on the inner walls of both sides of the track 52.

[0063] At the same time, rotating wheels 71 are rotatably mounted on both sides of the placement dish 41. The rotating wheels 71 are also made of a material with good wear resistance and corrosion resistance. Their surfaces are specially treated to reduce friction resistance when contacting the track 52 and the bumps 7, ensuring smooth movement. The rotating wheels 71 are suitable for moving within the track 52, and the height of the rotating wheels 71 is slightly smaller than the height of the track 52.

[0064] Furthermore, when the placement dish 41 moves from the spray tower 3 to the inside of the holding box 51 under the action of the first cylinder 53, the multiple sets of wheels 71 on both sides of the placement dish 41 will contact the protrusion 7. At the moment when the wheel 71 contacts the protrusion 7, due to the existence of the protrusion 7, the wheel 71 will be subjected to an upward impact force, thereby causing the placement dish 41 to produce a certain amplitude of bumps. During the bumping process, the filler balls inside the placement dish 41 will be subjected to impact forces in different directions, and the binding force between the filler balls that were originally adhered to each other will be broken, and they will gradually disperse, thereby effectively preventing the filler balls from adhering to each other, greatly simplifying the subsequent discharge and replacement operation process of the filler balls, and improving the efficiency and convenience of equipment maintenance.

[0065] Embodiment 3: When the discharge pipe 65 is filling the interior of the placement dish 41 with filler balls, the filler balls may accumulate on one side of the placement dish 41. This may cause the filler balls to overflow from the placement dish 41 during the process of returning the placement dish 41 to the spray tower 3. Therefore, improvements are made in the holding box 51. Specifically:

[0066] like Figure 11-12 As shown, a second cylinder 8 is provided on one side of the receiving box 51 near the first cylinder 53. The output end of the second cylinder 8 passes through the receiving box 51 and is fixedly mounted with a push plate 81. The push plate 81 is adapted to contact the top of the placement dish 41. The push plate 81 is adapted in shape and size to the top of the placement dish 41, and can cover the area on the top of the placement dish 41 where filler balls may accumulate. The push plate 81 does not damage the filler balls or the placement dish 41 when in contact with the top of the placement dish 41.

[0067] When the discharge pipe 65 has finished filling the placement dish 41, the second cylinder 8 drives the push plate 81 to move slowly toward the top of the placement dish 41. During the movement, the push plate 81 contacts the filler balls accumulated on the top of the placement dish 41 and gradually applies uniform pressure to them. This uniform pressure causes the filler balls to shift inside the placement dish 41. The filler balls originally accumulated on one side are gradually flattened and evenly distributed in the top space of the placement dish 41, realizing automatic leveling of the filler balls inside the placement dish 41, effectively avoiding the problem of filler balls overflowing when the placement dish 41 returns to the spray tower 3, and ensuring the normal operation of the equipment.

[0068] In summary, by providing the replacement component 5, the device allows the filler balls inside the placement dish 41 to be replaced quickly and stably, significantly reducing equipment downtime, ensuring the continuity of the exhaust gas purification operation, and providing a solid guarantee for the efficient operation of the production line.

[0069] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
