Description

Technical Field

[0001] This invention relates to the field of purification equipment technology, and in particular to a tobacco exhaust gas purification equipment based on modified cerium oxide composite adsorbent material. Background Technology

[0002] The exhaust gases generated during tobacco production contain pollutants such as soot, sulfur dioxide, nitrogen oxides, volatile organic compounds (such as benzene compounds), and carbon monoxide. These substances not only pollute the environment but may also irritate and damage the human respiratory system. Installing filtration devices can effectively remove particulate matter such as PM2.5 and PM10, as well as harmful gases, reducing environmental harm.

[0003] Chinese invention patent CN115671963A discloses a chemical workshop exhaust gas purification and treatment equipment. The treatment box has a cylindrical cavity inside and an exhaust pipe is connected to the top of the treatment box. The air intake device is located at the bottom of the treatment box and includes an air box with a circular cavity. The bottom of the air box is a frustum-shaped protrusion. The air box has a spiral channel inside and several outlets are distributed along the spiral channel on the top surface of the air box. The air intake pipe extends from the bottom of the air box to the center position and is connected to the center position of the spiral channel. The drain pipe is connected to the edge of the spiral channel from the outer wall of the treatment box. The air intake pipe is connected to the exhaust components of the workshop. A filter plate is installed in the outlet, and the filter plate is inclined downward.

[0004] Existing technology filters filters through filter plates in several outlets. After a period of use, the filter plates in the air box need to be cleaned. On the one hand, since the device does not have a structure for automatically removing the air box, the staff needs to manually remove the air box from the bottom or inside of the treatment box, which increases the difficulty of removing the filter plates. On the other hand, due to the limited space in the outlets, cleaning the filter plates is inconvenient, and may even increase the cleaning frequency of the filter plates and affect the probability of subsequent filtration work due to incomplete cleaning. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a tobacco exhaust gas purification and treatment device based on modified cerium oxide composite adsorbent material.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a tobacco exhaust gas purification and treatment device based on modified cerium oxide composite adsorption material, comprising a mounting base plate, a spray mechanism disposed on the mounting base plate, a filter box fixed on the mounting base plate, a mounting frame disposed in the filter box, a cerium oxide filter block detachably connected to the mounting frame, and a clamping mechanism disposed on the filter box and used to loosen or clamp the cerium oxide filter block when the mounting frame is raised or lowered. The cerium oxide filter block is a rectangular structure and is manufactured by a modification process. The top of the filter box is provided with a mounting groove that is inserted and matched with the mounting frame. The mounting groove and the mounting frame are sealed by a sealing gasket. The air outlet of the filter box is connected to the spray mechanism.

[0007] By adopting the above technical solution, the mounting frame is driven to rise by the clamping mechanism, and the cerium oxide filter block is released as the mounting frame rises. At this time, the cerium oxide filter block can be removed from the mounting frame and cleaned. After cleaning, the cerium oxide filter block is put back into the mounting frame, and then the mounting frame is driven to fall by the clamping mechanism. During this process, the cerium oxide filter block is clamped in the mounting frame, which facilitates the disassembly or installation of the cerium oxide filter block. At the same time, the entire cerium oxide filter block can be cleaned, reducing the probability of frequent filter plate cleaning due to inadequate cleaning and the probability of affecting subsequent filtration work.

[0008] Furthermore, the clamping mechanism includes a clamping assembly and a lifting assembly. The clamping assembly includes a first clamping plate with a U-shaped structure disposed within the mounting frame, a second clamping plate disposed within the mounting frame, a spring fixed between the second clamping plate and the inner sidewall of the mounting frame and in a retracted state, a connecting column rotatably mounted on the first clamping plate, and a sliding rod fixed within the mounting frame. An annular baffle that fits against the cerium oxide filter block is fixed within the mounting frame. The sliding rod passes through the second clamping plate and is slidably engaged. The first clamping plate passes through the mounting frame and is slidably engaged. The second clamping plate passes through the mounting frame and is slidably engaged. Both the first and second clamping plates are in contact with the surface of the cerium oxide filter block. An adjusting groove that slidably engages with the connecting column is provided through the second clamping plate. The distance between the adjusting groove and the bottom of the mounting frame gradually increases from the second clamping plate to the first clamping plate. A sliding through hole that slidably engages with the second clamping plate is provided through the sidewall of the mounting frame. An arc surface is provided on the second clamping plate, and the arc surface on the second clamping plate abuts against the inner sidewall of the mounting groove. The lifting assembly is used to drive the mounting frame to rise and fall.

[0009] By adopting the above technical solution, during the upward movement of the mounting frame, the first clamping plate connected to the mounting frame, the second clamping plate connected to the mounting frame, the spring connected to the second clamping plate, the connecting column connected to the second clamping plate, and the sliding rod connected to the mounting frame all rise until the second clamping plate separates from the mounting groove. The mounting groove releases its restriction on the second clamping plate, and the spring gradually extends, driving the second clamping plate to move away from the cerium oxide filter block. Due to the sliding connection between the adjusting groove and the connecting column, the distance between the adjusting groove and the bottom of the mounting frame gradually increases from the second clamping plate to the first clamping plate, thereby causing the connecting column and the first clamping plate connected to the connecting column to rise until the first clamping plate moves away from the cerium oxide filter block, thus achieving automatic release of the cerium oxide filter block. Similarly, during the downward movement of the mounting frame, the second clamping plate descends and contacts the mounting groove. The mounting groove compresses the second clamping plate, causing it to move towards the cerium oxide filter block. The spring is stressed and gradually contracts. Simultaneously, with the cooperation of the connecting column and the adjusting groove, the first and second clamping plates move synchronously towards the cerium oxide filter block, thereby achieving automatic clamping of the cerium oxide filter block.

[0010] Furthermore, the filter box has two cavities. The lifting assembly includes a connecting shaft rotatably installed in the cavity, a driven gear fixedly sleeved on the connecting shaft, a drive rod that passes through the filter box and is rotatably connected, a drive gear fixedly sleeved on the drive rod and meshing with it, and a drive motor fixed on the filter box and driving the drive rod to rotate. The cavity sidewall has a connecting through hole communicating with the mounting groove, and the mounting bracket sidewall has multiple tooth grooves that mesh with the driven gear.

[0011] By adopting the above technical solution, after the drive motor works, it drives the drive rod to rotate, thereby causing the driving gear connected to the drive rod, the driven gear meshing with the driving gear, and the connecting shaft connected to the driven gear to rotate. With the cooperation of the driven gear and the tooth groove, the purpose of automatic lifting and lowering of the mounting frame can be achieved.

[0012] Furthermore, the mounting base plate is provided with a storage component for storing and transporting the waste liquid generated by the spraying mechanism. The storage component includes a storage tank fixed on the mounting base plate, a delivery pump fixed on the storage tank, and a drain pipe fixed and connected to the inlet end of the delivery pump. The drain pipe extends into the storage tank, and multiple liquid inlet holes are provided through the side wall of the drain pipe inside the storage tank. The outlet end of the delivery pump is connected to the waste liquid treatment equipment.

[0013] By adopting the above technical solution, the waste liquid generated by the spraying mechanism will be transported to the storage tank for storage. At the same time, the delivery pump will work to extract the waste liquid from the storage tank through the drain pipe and the inlet hole, and discharge it to the waste liquid treatment equipment through the discharge end of the delivery pump for treatment, so that the spraying mechanism can continue to process.

[0014] Furthermore, the spraying mechanism includes a spraying assembly, a rotating assembly, a conveying assembly, and an air supply assembly. The spraying assembly includes a spraying tower fixed and connected to the top of the storage tank, a pump fixed to the storage tank, and a conveying pipe fixed and connected to the discharge end of the pump. The air outlet of the filter box is connected to the inside of the spraying tower. The feed end of the pump is connected to the storage device of the treatment liquid. The conveying pipe extends into the spraying tower. The spraying assembly includes a spray box fixed and connected to the conveying pipe and multiple atomizing nozzles connected to the spray box. The top of the atomizing nozzles is provided with a liquid delivery hole.

[0015] By adopting the above technical solution, after the pump starts working, it draws out the treatment liquid from the storage device through its inlet end and discharges it into the spray box through the conveying pipe. Finally, it is sprayed out by the atomizing nozzle. At the same time, the exhaust gas treated by the filter box is discharged into the spray tower through its outlet end. The exhaust gas comes into contact with the treatment liquid and undergoes further treatment, which improves the treatment effect of the device.

[0016] Furthermore, the atomizing nozzle is rotatably connected to the spray box, and the atomizing nozzle and the spray box are sealed by a rotating shaft seal. The rotating assembly includes a sealing shell fixed to the spray box, a feed pipe that passes through and is fixed to the sealing shell, a discharge pipe fixed to and connected to the sealing shell, and an impeller fixedly sleeved on the atomizing nozzle. Both the feed pipe and the discharge pipe are fixed to and connected to the spray box. The feed pipe is equipped with a one-way valve to control the liquid to be discharged from the spray box to the sealing shell, and the discharge pipe is equipped with a valve to control the liquid to be discharged from the sealing shell to the spray box.

[0017] By adopting the above technical solution, a portion of the treatment liquid is first discharged from the spray box into the feed pipe, then discharged from the feed pipe into the sealed shell, and finally discharged from the sealed shell into the spray box. During this process, the impeller and the atomizing nozzle connected to the impeller rotate. The centrifugal force generated by the rotation increases the contact force between the treatment liquid and the particles in the exhaust gas, which is conducive to the treatment liquid carrying the particles into the interior of the spray tower, thereby improving the treatment effect of the device.

[0018] Furthermore, the conveying assembly includes a reinforcing rod fixed inside the sealed housing and a spiral blade fixed on the reinforcing rod, and the spray box is fixed on the reinforcing rod.

[0019] By adopting the above technical solution, the exhaust gas in the filter box enters the spray tower through its outlet. Then, the exhaust gas rotates and rises along the spiral blades, which increases the movement distance of the exhaust gas and the contact time between the exhaust gas and the treatment liquid, thereby improving the treatment effect.

[0020] Furthermore, the air supply assembly includes an air supply pipe fixed and connected to the atomizing nozzle, the air supply pipe passing through the spray box and fixed, the air supply assembly also includes an air supply box fixed and connected to the air supply pipe, a delivery pipe fixed and connected to the air supply box, and a high-pressure air pump fixed to the storage box, the delivery pipe extending to the outside of the spray tower, and the delivery pipe being fixed and connected to the air outlet of the high-pressure air pump.

[0021] By adopting the above technical solution, after the high-pressure air pump starts working, it first discharges air through its outlet to the delivery pipe, then from the delivery pipe to the air supply box, then from the air supply box to the air supply pipe, and finally from the air supply pipe to the atomizing nozzle, where it atomizes the treatment liquid inside the atomizing nozzle. The atomized droplets have smaller particle size and larger specific surface area, increasing the contact area with pollutants in the exhaust gas, which helps to achieve more efficient mass transfer reaction, thereby improving the filtration effect of the device.

[0022] Furthermore, a heating assembly is provided on both the spray tower and the storage tank. The heating assembly includes a heater fixed to the storage tank and an air inlet pipe fixed to and connected to the air inlet end of the heater. The end of the air inlet pipe away from the heater is fixed to and connected to the top of the spray tower. The air outlet end of the heater is connected to an external heating system.

[0023] By adopting the above technical solution, the exhaust gas treated in the spray tower is discharged into the heater through the inlet pipe and the inlet end of the heater. The heater dries the exhaust gas and discharges it to the heating system through the outlet end of the heater to achieve energy recycling. At the same time, the dried gas reduces the probability of corrosion to the gas supply pipeline.

[0024] Furthermore, the top of the filter box is provided with a mounting through hole that communicates with the mounting groove, and the top of the mounting bracket is fixed with a sealing plate that is inserted into the mounting through hole.

[0025] By adopting the above technical solution, the sealing plate improves the sealing effect of the connection between the mounting groove and the mounting bracket.

[0026] In summary, the present invention has the following beneficial effects: In this application, by setting a clamping mechanism, the disassembly or installation of the cerium oxide filter block is facilitated, and the entire cerium oxide filter block can be cleaned, reducing the probability of the filter plate cleaning frequency caused by inadequate cleaning and the probability of affecting subsequent filtration work.

Detailed Implementation

[0038] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0039] like Figure 1-10 As shown in the embodiment of this application, a tobacco exhaust gas purification device based on modified cerium oxide composite adsorbent material is disclosed. It includes a mounting base plate 1, a clamping mechanism 7, a storage component 8, a spraying mechanism 2, and a heating component 9. A filter box 3 is fixed to the top of the mounting base plate 1, and a mounting frame 5 is installed inside the filter box 3. The top of the filter box 3 has a mounting groove 4 that engages with the mounting frame 5. Two cavities 11 are formed on the filter box 3. Connecting through holes 12 communicating with the mounting groove 4 are formed on the sidewalls of the cavities 11. The number of connecting through holes 12 is equal to the number of cavities 11, and their positions correspond one-to-one. The mounting groove 4 and the mounting frame 5 are sealed together by a sealing gasket. The air outlet of the filter box 3 is connected to the spraying mechanism 2 (the filter box 3 is fixed and connected to the spraying mechanism 2 via an air supply pipe). A cerium oxide filter block 6 is inserted into the mounting frame 5. The cerium oxide filter block 6 has a rectangular structure and is manufactured using a modification process. An annular baffle 13 that fits against the cerium oxide filter block 6 is fixed inside the mounting frame 5. The clamping mechanism 7 drives the mounting frame 5 to rise, simultaneously releasing the cerium oxide filter block 6. This allows the cerium oxide filter block 6 to be removed from the mounting frame 5 for cleaning. After cleaning, the cerium oxide filter block 6 is placed back into the mounting frame 5. Then, the clamping mechanism 7 drives the mounting frame 5 to descend, clamping the cerium oxide filter block 6 within the mounting frame 5. This facilitates the disassembly and installation of the cerium oxide filter block 6 and allows for the cleaning of the entire cerium oxide filter block 6, reducing the probability of insufficient cleaning leading to frequent filter plate cleaning and impacting subsequent filtration operations.

[0040] A clamping mechanism 7 is mounted on the filter box 3. The clamping mechanism 7 includes a clamping assembly 71 and a lifting assembly 72. The clamping assembly 71 includes a first clamping plate 711, a second clamping plate 712, a spring 713, a connecting post 714, and a sliding rod 716. The first clamping plate 711 is located inside the mounting frame 5 and has a U-shaped structure. There are two first clamping plates 711, which pass through the bottom and top of the inner side of the mounting frame 5 and are slidably engaged. The connecting post 714 is rotatably mounted on the first clamping plate 711, and there are two connecting posts 714 on each first clamping plate 711. There are two second clamping plates 712 located inside the mounting frame 5. The two second clamping plates 712 pass through the inner walls on both sides of the mounting frame 5 and are slidably engaged. An adjustment groove 715 is provided on the second clamping plate 712 to slide with the connecting post 714. Each second clamping plate 712 has two adjustment slots 715, and the distance between two adjustment slots 715 on the same side gradually decreases from the first clamping plate 711 to the second clamping plate 712. A sliding through hole 10 is provided through the side wall of the mounting frame 5, which slides with the second clamping plate 712. The inner side wall of the mounting groove 4 on the second clamping plate 712 abuts against the arc surface. Both the first clamping plate 711 and the second clamping plate 712 are in contact with the surface of the cerium oxide filter block 6. The spring 713 is fixed between the second clamping plate 712 and the inner side wall of the mounting frame 5 and is in a retracted state. The sliding rod 716 is fixed inside the mounting frame 5, and the sliding rod 716 passes through the second clamping plate 712 and slides with it. During the ascent of the mounting frame 5, the first clamping plate 711 connected to the mounting frame 5, the second clamping plate 712 connected to the mounting frame 5, the spring 713 connected to the second clamping plate 712, the connecting column 714 connected to the second clamping plate 712, and the sliding rod 716 connected to the mounting frame 5 all rise until the second clamping plate 712 separates from the mounting groove 4. The mounting groove 4 releases its restriction on the second clamping plate 712, and the spring 713 gradually extends and drives the second clamping plate 712 to move away from the cerium oxide filter block 6. Since the adjusting groove 715 is slidably connected to the connecting column 714, the distance between the adjusting groove 715 and the bottom of the mounting frame 5 gradually increases from the second clamping plate 712 to the first clamping plate 711. This causes the connecting column 714 and the first clamping plate 711 connected to the connecting column 714 to rise until the first clamping plate 711 moves away from the cerium oxide filter block 6, thereby achieving automatic release of the cerium oxide filter block 6. Similarly, during the descent of the mounting bracket 5, the second clamping plate 712 descends and contacts the mounting groove 4. The mounting groove 4 presses the second clamping plate 712 toward the cerium oxide filter block 6, and the spring 713 is stressed and gradually contracts. At the same time, with the cooperation of the connecting column 714 and the adjusting groove 715, the first clamping plate 711 and the second clamping plate 712 move synchronously toward the cerium oxide filter block 6, thereby achieving automatic clamping of the cerium oxide filter block 6.

[0041] The lifting assembly 72 is used to drive the mounting frame 5 to rise and fall. The lifting assembly 72 includes a connecting shaft 721, a driven gear 722, a drive rod 723, a driving gear 724, and a drive motor 725. The connecting shaft 721 is rotatably mounted in the cavity 11, and the driven gear 722 is fixedly sleeved on the connecting shaft 721. The drive rod 723 passes through and is rotatably connected to the filter box 3, and the driving gear 724 is fixedly sleeved on the drive rod 723 and meshes with it. The drive motor 725 is fixed on the filter box 3 and drives the drive rod 723 to rotate. The side wall of the mounting frame 5 has a toothed groove 726 that meshes with the driven gear 722. There are two sets of toothed grooves 726, and each set of toothed grooves 726 has multiple toothed grooves. The number of connecting shafts 721, the number of driven gears 722, the number of driving gears 724, the number of sets of toothed grooves 726, and the number of cavities 11 are all equal and their positions correspond one-to-one. After the drive motor 725 starts working, it drives the drive rod 723 to rotate, which causes the drive gear 724 connected to the drive rod 723, the driven gear 722 meshing with the drive gear 724, and the connecting shaft 721 connected to the driven gear 722 to rotate. With the cooperation of the driven gear 722 and the tooth groove 726, the purpose of automatic lifting of the mounting frame 5 can be achieved.

[0042] The storage component 8 is mounted on the mounting base plate 1 and is used to store and transport the waste liquid generated by the spraying mechanism 2. The storage component 8 includes a storage tank 81, a delivery pump 82, and a drain pipe 83. The storage tank 81 is fixed to the mounting base plate 1. The delivery pump 82 is fixed to the storage tank 81, and the drain pipe 83 is fixed and connected to the inlet end of the delivery pump 82. The outlet end of the delivery pump 82 is connected to the waste liquid treatment equipment. The drain pipe 83 extends into the storage tank 81, and multiple inlet holes are provided through the side wall of the storage tank 81. The waste liquid generated by the spraying mechanism 2 is transported to the storage tank 81 for storage. Simultaneously, the delivery pump 82 operates, extracting the waste liquid from the storage tank 81 through the drain pipe 83 and the inlet holes, and discharging it through the outlet end of the delivery pump 82 to the waste liquid treatment equipment for further processing, ensuring continuous operation of the spraying mechanism 2.

[0043] The spraying mechanism 2 is mounted on the mounting base plate 1 and includes a spraying assembly 21, a rotating assembly 22, a conveying assembly 23, and an air supply assembly 24. The spraying assembly 21 includes a spraying tower 211, a pump 212, a conveying pipe 213, a spraying box 214, and atomizing nozzles 215. The spraying tower 211 is fixed to and connected to the top of the storage box 81, and the air outlet of the filter box 3 is connected to the inside of the spraying tower 211. The pump 212 is fixed to the storage box 81, and its inlet is connected to the storage device for the treated liquid. The conveying pipe 213 is fixed to and connected to the outlet of the pump 212, and extends into the spraying tower 211. The spray box 214 is fixed and connected to the conveying pipe 213. The atomizing nozzle 215 rotates and is connected to the spray box 214. The atomizing nozzle 215 and the spray box 214 are sealed by a rotary shaft seal. Multiple atomizing nozzles 215 are provided, and a liquid delivery hole is provided through the top of each atomizing nozzle 215. After the pump 212 starts working, it draws the treatment liquid from the storage device through its inlet end and discharges it into the spray box 214 through the conveying pipe 213. Finally, it is sprayed out by the atomizing nozzle 215. At the same time, the exhaust gas treated by the filter box 3 is discharged into the spray tower 211 through its outlet end. The exhaust gas comes into contact with the treatment liquid and undergoes further treatment, improving the treatment effect of the device.

[0044] The rotating assembly 22 includes a sealing shell 221, a feed pipe 222, a discharge pipe 223, and an impeller 224. The sealing shell 221 is fixed to the spray box 214. The feed pipe 222 is fixed to and connected to the sealing shell 221, and the discharge pipe 223 is fixed to and connected to the sealing shell 221. Both the feed pipe 222 and the discharge pipe 223 are fixed to and connected to the spray box 214. A one-way valve is provided on the feed pipe 222 to control the discharge of liquid from the spray box 214 to the sealing shell 221. A valve is provided on the discharge pipe 223 to control the discharge of liquid from the sealing shell 221 to the spray box 214. The impeller 224 is fixedly sleeved on the atomizing nozzle 215. A portion of the treatment liquid is first discharged from the spray box 214 into the feed pipe 222, then from the feed pipe 222 into the sealing shell 221, and finally from the sealing shell 221 back into the spray box 214. During this process, both the impeller 224 and the atomizing nozzle 215 connected to the impeller 224 rotate. The centrifugal force generated by the rotation increases the contact force between the treatment liquid and the particles in the exhaust gas, which helps the treatment liquid carry the particles into the interior of the spray tower 211, thereby improving the treatment effect of the device.

[0045] The conveying assembly 23 includes a reinforcing rod 231 and a spiral blade 232, with the reinforcing rod 231 fixed inside the sealing housing 221. The spray box 214 is fixed to the reinforcing rod 231, and the spiral blade 232 is also fixed to the reinforcing rod 231. The exhaust gas in the filter box 3 enters the spray tower 211 through its outlet. The exhaust gas then rises along the spiral blade 232, increasing the distance the exhaust gas travels and the contact time between the exhaust gas and the treated liquid, thus improving the treatment effect.

[0046] The air supply assembly 24 includes an air supply pipe 241, an air supply box 242, a delivery pipe 243, and a high-pressure air pump 244. The air supply pipe 241 is fixed and connected to the atomizing nozzle 215. The air supply pipe 241 passes through the spray box 214 and is fixed thereto. The air supply box 242 is fixed and connected to the air supply pipe 241. The delivery pipe 243 is fixed and connected to the air supply box 242 and extends to the outside of the spray tower 211. The high-pressure air pump 244 is fixed to the storage box 81, and the delivery pipe 243 is fixed and connected to the outlet end of the high-pressure air pump 244. After the high-pressure air pump 244 starts working, it first discharges air through its outlet to the delivery pipe 243, then from the delivery pipe 243 to the air supply box 242, then from the air supply box 242 to the air supply pipe 241, and finally from the air supply pipe 241 to the atomizing nozzle 215, where it atomizes the treatment liquid. The atomized droplets have smaller particle size and larger specific surface area, increasing the contact area with pollutants in the exhaust gas, which helps to achieve more efficient mass transfer reaction, thereby improving the filtration effect of the device.

[0047] Heating components 9 are jointly mounted on the spray tower 211 and the storage tank 81. Heating components 9 include a heater 91 and an inlet pipe 92. The heater 91 is fixed to the storage tank 81, and its outlet is connected to an external heating system. The inlet pipe 92 is fixed and connected to the inlet of the heater 91, with the end of the inlet pipe 92 away from the heater 91 fixed and connected to the top of the spray tower 211. The treated exhaust gas in the spray tower 211 is discharged into the heater 91 through the inlet pipe 92 and the inlet of the heater 91. The heater 91 dries the exhaust gas and discharges it to the heating system through its outlet, thus achieving energy recycling. Simultaneously, the dried gas reduces the probability of corrosion on the gas supply pipe 241.

[0048] The top of the filter box 3 has a mounting through hole 14 that communicates with the mounting groove 4, and the top of the mounting bracket 5 is fixed with a sealing plate 15 that is inserted into the mounting through hole 14. The sealing plate 15 improves the sealing effect of the connection between the mounting groove 4 and the mounting bracket 5.
