Description

Technical Field

[0001] This invention belongs to the field of electrolytic aluminum waste gas purification technology, specifically an aluminum electrolytic cell waste gas purification and treatment device. Background Technology

[0002] When aluminum substrates are made into offset printing plates, the aluminum substrates need to undergo electrolytic roughening treatment. After roughening, the aluminum substrates are oxidized, and a photosensitive material is coated on the surface of the aluminum substrates. After drying and cutting, offset printing plates are formed.

[0003] In current technologies, the electrolysis of aluminum blocks generates a certain amount of harmful aluminum waste gas. This waste gas contains gaseous and solid substances such as hydrogen chloride and solid dust. These harmful substances are highly irritating and corrosive, and can cause pneumoconiosis in nearby employees. As a result, a high concentration of hydrogen chloride is generated in the waste gas during the electrolysis of aluminum. Existing purification equipment uses activated alumina particles as an adsorbent to adsorb hydrogen chloride, thereby forming aluminum chloride. This method has a fast reaction rate and high efficiency.

[0004] However, the aluminum chloride at the air inlet of the aluminum chloride tank is located at the very front. The aluminum chloride in this area faces the highest concentration of hydrogen chloride and is constantly under high adsorption load, making it very easy for the aluminum chloride at this location to reach saturation. At the same time, solid dust particles inside the aluminum gas can also easily cause blockage in this area, preventing aluminum waste gas from effectively entering the interior of the aluminum chloride tank. If the machine is shut down and replaced at this time, the waste gas treatment efficiency per unit time will decrease and the aluminum waste gas emission concentration will increase. Moreover, the aluminum chloride at the tail end of the aluminum chloride tank is far away and has not yet reached the adsorption saturation state. If it is replaced directly, it will waste aluminum chloride resources. If it is not replaced, it will further affect the purification of the aluminum chloride tank.

[0005] Because the activated alumina particles, which simultaneously adsorb a large amount of hydrogen chloride, will clump together inside the aluminum chloride tank due to the stickiness of the hydrogen chloride. These clumps cannot be detached on their own and require manual intervention or external force to break the weak adhesion between the particles. Manual removal requires stopping the machine, affecting work efficiency, while mechanical removal presents several problems because the mechanical equipment cannot rotate with the machine or move with it.

[0006] Therefore, the present invention provides a waste gas purification and treatment device for aluminum electrolysis cells. Summary of the Invention

[0010] Preferably, the magnetic block on the surface of the slide rod is disposed inside the hollow groove, and a docking groove is formed on the inner surface of the other end of the slide rod. A docking cover disposed at one end of the limiting rod and movably sleeved with one end of the elastic wire is movably sleeved on the inner wall of the docking groove.

[0011] Preferably, an inner sleeve is fixedly connected to one side of the inner wall of the exhaust gas purification tank. An opening is provided at the upper and lower edges of the inner sleeve. An opening is provided at the inner wall of the rotating cylinder where it is connected to the collection trough. The opening is movably connected to the opening. A conical groove is provided at one end of the threaded rod. A limiting protrusion is provided at one side edge of the collection plate. The outer surface of the limiting protrusion is movably sleeved on the surface of the opening.

[0012] Preferably, a docking sleeve is provided on the outer surface of one end of the exhaust gas purification tank, and a support plate is fixedly connected to the other side surface of the exhaust gas purification tank. Two sets of hydraulic rods are provided on the outer surface of the support plate, and the output ends of the two sets of hydraulic rods are connected to the surface of a small electric motor.

[0013] Preferably, the output end of the small electric motor is provided with a conical head at the point where it fits into the conical groove, and a motor is provided on the surface of the support plate at the center of one side of the exhaust gas purification tank.

[0014] Preferably, an exhaust pipe is fixedly connected to one side of the exhaust gas purification tank, and the position of the exhaust pipe is at the same level as the position of the docking sleeve.

[0015] Preferably, the output end of the motor is fixedly connected to a sealing disc, and the outer surface of the sealing disc is fixedly connected to an arc-shaped plate that is movably sleeved on the inner wall of the inner sleeve.

[0016] Preferably, the upper and lower surfaces of the arc-shaped plate are provided with slots, and multiple stirring claws are fixedly connected to the inner wall of the arc-shaped plate.

[0017] Preferably, a support frame is provided on the outer surface of the exhaust gas purification tank, a waste filter tank is provided on the inner wall of the support frame, a gas guide pipe is fixedly connected to the receiving end of the waste filter tank, and the other end of the gas guide pipe extends to the inner wall of the exhaust gas purification tank.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. The aluminum electrolysis cell exhaust gas purification and treatment equipment of the present invention, when the ventilated extrusion plate moves on the surface of the limiting rod, it pushes the sealing sleeve on the surface of the limiting rod, thereby driving the sliding rod on the inner wall of the sealing sleeve to move towards the collecting plate, and compressing the elastic wire inside the docking cover. The moving sliding rod will move away from the inner wall of the soft sleeve. The repulsion between the same poles of magnetic block one and magnetic block two will be reduced due to the misalignment, so that the soft sleeve can be more relaxed. As the activated alumina particles are squeezed by the ventilated extrusion plate, they gradually adhere to the surface of the limiting rod and the soft sleeve, and firmly adhere the soft sleeve to the surface of the limiting rod. If a few activated alumina particles are left in the gap between the soft sleeve and the limiting rod, it will not affect the adhesion of the soft sleeve, so that the aluminum chloride particles can be firmly confined inside the collecting tank to form a whole.

[0020] 2. In the aluminum electrolysis cell exhaust gas purification equipment of the present invention, when the activated alumina particles need to be replaced, the ventilated extrusion disc will move in the direction of the small electric motor under the reverse drive of the small electric motor. At this time, some of the compacted activated alumina particles will not be compacted and will easily fall from the inside of the collection tank and between the collection plate and the ventilated extrusion disc. Meanwhile, aluminum chloride particles that have absorbed hydrogen chloride will remain inside the collection tank. At this time, with one end of the slide rod no longer restricted by the sealing sleeve, the slide rod will be pushed in the reverse direction by the elastic wire. When the rod is pushed back to its original position, the magnetic block one on the surface of the sliding rod will come into contact with the magnetic block two on the inner wall of the soft sleeve during the movement. At this time, the repulsion of like poles of the magnets will cause the soft sleeve to be slightly pushed inside the aluminum chloride particles. Under the internal pushing force, the density of the aluminum chloride particles will be easily destroyed, and the firmness of the aluminum chloride particles will be destroyed from the inside out, making the aluminum chloride particles fall out of the collection tank more easily. This destructive force from the inside out can further reduce the integrity of the aluminum chloride particles, so that they can be crushed and granulated more quickly.

[0021] 3. The aluminum electrolysis cell exhaust gas purification equipment of the present invention, when the electric furnace produces electrolytic aluminum, the exhaust gas generated by electrolysis is conveyed into the collection tank through the docking sleeve. At this time, the active alumina particles inside the collection tank, located between the collection plate and the permeable extrusion plate, adsorb hydrogen chloride for a period of time to form aluminum chloride. The motor rotates the rotating cylinder inside the exhaust gas purification tank, causing the collection tank filled with aluminum chloride to move away from the exhaust port of the docking sleeve. The exhaust port of the docking sleeve is sealed by the rotation of the rotating cylinder, causing the exhaust gas to accumulate inside the docking sleeve. When the aluminum chloride moves to the rotating cylinder... At its highest point, opening one on the surface of the inner sleeve connects with opening two on the surface of the collection trough. Some aluminum chloride particles and activated alumina particles inside the collection trough fall into the inner sleeve under their own gravity and come into contact with the activated alumina particles inside the inner sleeve. Meanwhile, the activated alumina particles at the bottom of the inner sleeve also enter the empty collection trough under their own gravity. This achieves the effect of using the rotating cylinder to peel off the aluminum chloride and activated alumina particles inside the collection trough during rotation, and to fill the collection trough with activated alumina particles mixed with a small amount of fluorinated material.

Detailed Implementation

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] like Figures 3 to 6As shown, an embodiment of the present invention provides an aluminum electrolysis cell exhaust gas purification device, comprising an exhaust gas purification tank 12 and a rotating cylinder a1 movably fitted inside the exhaust gas purification tank 12, and four sets of collection troughs a2 formed inside the rotating cylinder a1. Activated alumina particles, with a diameter of 3-5 mm, are filled inside the collection troughs a2. A collection plate a5 is provided at the connection between the rotating cylinder a1 and the collection troughs a2. Four fixedly connected limiting rods a9 and a movably fitted threaded rod a6 are respectively provided on the surface of the collection plate a5. A permeable extrusion disc a7 is threaded onto the outer surface of the threaded rod a6, and the surface of the permeable extrusion disc a7 is movably fitted onto the limiting rods a9. On the outer surface of 9, a small electric motor 125 is provided at one end of the threaded rod a6. A sealing sleeve a92 is movably sleeved on the surface of the limiting rod a9 and at the edge of the ventilated extrusion plate a7. A sliding rod a95 is movably sleeved on the inner wall of the limiting rod a9. Multiple sets of magnetic blocks a97 are provided on the outer surface of the sliding rod a95. The inner wall of the sealing sleeve a92 is provided on one end surface of the sliding rod a95. An elastic wire a910 is fixedly connected to the other end of the sliding rod a95. A soft sleeve a911 is oscillatingly connected to the outer surface of the limiting rod a9. Multiple magnetic blocks a912 are provided on the inner wall of the soft sleeve a911, and the magnetic blocks a912 and magnetic blocks a97 have the same pole on their opposing surfaces.

[0033] When the ventilated extrusion disc a7 moves on the surface of the limiting rod a9, it pushes the sealing sleeve a92 on the surface of the limiting rod a9, thereby causing the sliding rod a95 on the inner wall of the sealing sleeve a92 to move towards the collecting plate a5, and compressing the elastic wire a910 inside the docking cover a99. The moving sliding rod a95 will move away from the inner wall of the soft sleeve a911, and the repulsion between magnetic block one a97 and magnetic block two a912 will be reduced due to the misalignment. The thrust of the material allows the soft sleeve a911 to loosen further. As the activated alumina particles are squeezed by the ventilated extrusion disc a7, they gradually adhere to the surfaces of the limiting rod a9 and the soft sleeve a911, firmly adhering the soft sleeve a911 to the surface of the limiting rod a9. Even if a few activated alumina particles remain in the gap between the soft sleeve a911 and the limiting rod a9, it will not affect the adhesion of the soft sleeve a911, allowing the aluminum chloride particles to be firmly confined inside the collection trough a2, forming a whole.

[0034] When the activated alumina particles need to be replaced later, the ventilated extrusion disc a7 will move in the direction of the small electric motor 125 under the reverse drive of the small electric motor 125. At this time, some of the compacted activated alumina particles will not be compacted and will easily fall from the inside of the collection trough a2 and between the collection plate a5 and the ventilated extrusion disc a7. Meanwhile, aluminum chloride particles that have absorbed hydrogen chloride will remain inside the collection trough a2. At this time, after one end of the slide rod a95 is no longer restricted by the sealing sleeve a92, the slide rod a95 will be pushed back to its original position by the reverse push of the elastic wire a910. During the movement, the magnetic block a97 on the surface of the slide bar a95 will come into contact with the magnetic block a912 on the inner wall of the soft sleeve a911. At this time, the repulsion of like poles of the magnets will cause the soft sleeve a911 to be slightly pushed inside the aluminum chloride particles. Under the internal pushing force, the density of the aluminum chloride particles will be easily destroyed, and the firmness of the aluminum chloride particles will be destroyed from the inside out, making the aluminum chloride particles fall off the collection tank a2 more easily. This destructive force from the inside out can further reduce the integrity of the aluminum chloride particles, so that they can be crushed and granulated more quickly.

[0035] Inside the rotating cylinder a1, there are four sets of collecting troughs a2, which are essentially independent of each other under the constraint of the inner sleeve a3. Exhaust gas flows only from a single collecting trough a2 at a time. One end of the collecting trough a2 supplies exhaust gas, while the other end absorbs it. Furthermore, the flow velocity at the inlet is much slower than the extraction velocity due to the obstruction of the internal activated alumina particles. This prevents the exhaust gas inside the collecting trough a2 from leaking out through the gap between the rotating cylinder a1 and the inner sleeve a3, and also drives the exhaust gas inside the inner sleeve to... The exhaust gas inside the inner sleeve a3 is absorbed through the waste filter tank 111 and the air guide pipe 112, so there is basically no exhaust gas leakage path. Moreover, the collection tank a2 is an almost completely closed tank, with only the air inlet and outlet on both sides of the main tank opening. Except for external suction, there is no power source inside to provide exhaust gas flow. Once the external air extraction device stops, the exhaust gas inside will remain inside. Without a power source, the exhaust gas will not flow or leak out on its own.

[0036] like Figures 1 to 7As shown, the limiting rod a9 has a limiting groove a91 and a hollow groove a94 inside. A pushing plate a93 is provided on the inner wall of the sealing sleeve a92. The position where the pushing plate a93 contacts the sliding rod a95 is located inside the limiting groove a91, and a clamping block a96 is provided at the contact position between the pushing plate a93 and the sliding rod a95. A magnetic block a97 on the surface of the sliding rod a95 is located inside the hollow groove a94. A mating groove a98 is provided on the inner surface of the other end of the sliding rod a95. The inner wall of the mating groove a98 is open. A connecting cover a99 is provided at one end of the limiting rod a9 and is movably connected to one end of the elastic wire a910. An inner sleeve a3 is fixedly connected to one side of the inner wall of the exhaust gas purification tank 12. An opening a14 is provided at the upper and lower edges of the inner sleeve a3. An opening a2 a11 is provided on the inner wall of the rotating cylinder a1 at the position connected to the collection trough a2. The opening a14 and the opening a2 a11 are movably connected. A conical groove a8 is provided at one end of the threaded rod a6. A limiting protrusion a1 is provided at one side edge of the collection plate a5. 0. The outer surface of the limiting protrusion a10 is movably fitted onto the surface of the opening a11. A mating sleeve 121 is provided on the outer surface of one end of the exhaust gas purification tank 12. A support plate 122 is fixedly connected to the other side surface of the exhaust gas purification tank 12. Two sets of hydraulic rods 124 are provided on the outer surface of the support plate 122. The output ends of the two sets of hydraulic rods 124 are connected to the surface of the small electric motor 125. A conical head 126 is provided at the output end of the small electric motor 125 where it fits against the conical groove a8. The support plate 122... A motor 127 is installed at the center of one side of the surface of the exhaust gas purification tank 12. An exhaust pipe 123 is fixedly connected to one side of the exhaust gas purification tank 12. The position of the exhaust pipe 123 is at the same level as the position of the docking sleeve 121. A support frame 11 is installed on the outer surface of the exhaust gas purification tank 12. A waste filter tank 111 is installed on the inner wall of the support frame 11. A guide pipe 112 is fixedly connected to the receiving end of the waste filter tank 111. The other end of the guide pipe 112 extends to the inner wall of the exhaust gas purification tank 12.

[0037] The dwell time of each new collection trough a2 is one hour as a threshold. When the inner sleeve a3 is replaced with a new collection trough a2, it only needs to be rotated clockwise by 1 / 4 turn. The rotation time is set to 10 seconds each time, including the rotation time and angle adjustment time. The waste gas stops conveying for 10 seconds, which will not cause too much blockage.

[0038] When the aluminum substrate undergoes electrolytic roughening, the waste gas generated on the surface of the aluminum substrate is conveyed into the collection tank a2 through the docking head 121. At this time, the active alumina particles inside the collection tank a2, located between the collection plate a5 and the ventilated extrusion plate a7, adsorb hydrogen chloride for a period of time to form aluminum chloride. In conjunction with the motor 127, the rotating cylinder a1 inside the waste gas purification tank 12 rotates, causing the collection tank a2 filled with aluminum chloride to move away from the exhaust port of the docking head 121. At this time, the exhaust port of the docking head 121 is sealed by the rotation of the rotating cylinder a1, causing the waste gas to accumulate inside the docking head 121. When the aluminum chloride moves to the highest point of the rotating cylinder a1, The opening a4 on the surface of the inner sleeve a3 will connect with the opening a11 on the surface of the collection tank a2. Some aluminum chloride particles and activated alumina particles inside the collection tank a2 will fall into the inner sleeve a3 under their own gravity and come into contact with the activated alumina particles inside the inner sleeve a3. The activated alumina particles at the bottom of the inner sleeve a3 will also enter the empty collection tank a2 under their own gravity. This achieves the effect of using the rotating cylinder a1 to peel off the aluminum chloride and activated alumina particles inside the collection tank a2 during the rotation process, and filling the collection tank a2 with activated alumina particles mixed with a small amount of fluoride.

[0039] At this point, the inner sleeve a3 is already filled with new activated alumina particles. When aluminum chloride enters the inner sleeve a3, the aluminum chloride and activated alumina particles in the collection trough a2 will mix together due to the impact force. This causes the activated alumina particles, carrying aluminum chloride, to be placed at the top layer inside the inner sleeve a3. Meanwhile, the activated alumina particles at the bottom of the inner sleeve a3 will enter the collection trough a2 for filling. As the bottom activated alumina particles continuously enter the collection trough a2, the top layer of aluminum chloride and activated alumina particles will also... As the flow continues, aluminum chloride and activated alumina particles are carried into the collection tank a2. The motor 127 accelerates the rotation speed of the rotating drum a1, which shortens the contact time between the activated alumina particles and the waste gas from electrolytic aluminum in the collection tank a2, increasing the number of replacements. When activated alumina particles mixed with hydrogen chloride re-enter the collection tank a2, the adsorption effect of the activated alumina particles on hydrogen chloride will decrease, making it unsuitable for long-term adsorption. Increasing the rotation speed and reducing the contact time can effectively prolong the hydrogen chloride adsorption effect.

[0040] After the collection trough a2 is filled with new activated alumina particles, it comes into contact with the air vent of the docking head 121 under the drive of the motor 127. Since the activated alumina particles inside the collection trough a2 are in a loose state at this time, the contact effect between the hydrogen chloride waste gas and the activated alumina particles is insufficient. At this time, the hydraulic rod 124 pushes the small electric motor 125, and the conical head 126 at one end of the small electric motor 125 docks with the conical groove a8 on the surface of one end of the threaded rod a6. At this time, the small electric motor 125 rotates the threaded rod a6, and under the limitation of the limit rod a9, the ventilated extrusion plate a7 moves towards the collection plate a5. During the movement, the activated alumina particles inside the collection trough a2 are compressed, so that the relatively loose activated alumina particles form a relatively dense aggregate, so that the waste gas can contact the activated alumina particles to the maximum extent when passing through the activated alumina particles, reducing the leakage of waste gas.

[0041] like Figure 7 As shown, a sealing disc 1271 is fixedly connected to the output end of the motor 127. An arc-shaped plate 1272 is fixedly connected to the outer surface of the sealing disc 1271 and is movably sleeved on the inner wall of the inner sleeve a3. The upper and lower surfaces of the arc-shaped plate 1272 are provided with slots 1273. Multiple stirring claws 1274 are fixedly connected to the inner wall of the arc-shaped plate 1272.

[0042] During the falling process, aluminum chloride particles will come into contact with and collide with the stirring claws 1274 inside the arc plate 1272. The external impact can quickly destroy the adsorption and firmness of the aluminum chloride particle cluster, allowing it to quickly loosen and granulate. As the activated alumina particles gradually transform into aluminum chloride particles, they are replaced with new aluminum chloride particles.

[0043] Working principle: When the aluminum substrate is subjected to electrolytic roughening, the waste gas generated on the surface of the aluminum substrate will be transported into the interior of the collection tank a2 through the docking head 121. At this time, the interior of the collection tank a2 will be filled with activated alumina particles. When the waste gas containing activated alumina particles flows on the surface of activated alumina particles, it will use the pores on the surface of activated alumina particles to adsorb alumina, thereby forming a layer of aluminum chloride on the surface of activated alumina particles. The aluminum chloride can be replaced later.

[0044] The remaining waste gas after adsorbing hydrogen chloride is guided into the adsorption reactor, high-efficiency bag filter and wet desulfurization system through exhaust pipe 123 to carry out multiple stages of purification treatment, so that the waste gas from electrolytic aluminum can reach the level of being discharged into the atmosphere.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
