Description

Technical Field

[0001] The invention relates to a rapid recovery device for fluorine chemical flue gas and relates to the technical field of fluorine chemical tail gas treatment. Background Art

[0002] The flue gas generated during the fluorine chemical production process usually contains harmful components such as hydrogen fluoride, silicon tetrafluoride, and sulfur dioxide. Direct discharge will seriously pollute the environment. The core goal of the rapid recovery device is to efficiently capture and recover fluorine resources in the flue gas while achieving standard emissions.

[0003] The patent with patent announcement number CN218530333U relates to a fluorination process tail gas treatment device, including: a carbon reactor and a leaching tower; a first tail gas inlet and a carbon adding port are provided at the upper part of the carbon reactor, and a first tail gas outlet is provided at the lower part of the carbon reactor; a second tail gas inlet and an alkali liquid outlet are provided at the lower part of the leaching tower, and a second tail gas outlet and an alkali liquid inlet are provided at the upper part of the leaching tower; the first tail gas outlet of the carbon reactor is connected to the second tail gas inlet of the leaching tower. The technical solution of this patent combines the carbon reactor and the leaching tower, and effectively absorbs fluorine, hydrogen fluoride, etc. in the tail gas through charcoal adsorption and alkali liquid elution, effectively reducing the pollution of the tail gas to the environment. It has the advantages of simple structure, low cost, easy processing, simple operation and easy maintenance, which is beneficial to reducing costs and increasing efficiency of the production line.

[0004] The above patent has the function of improving the absorption efficiency of harmful gases such as fluorine and hydrogen fluoride. By introducing a carbon reactor, the tail gas after leaching is subjected to secondary purification to reduce pollution to the environment. However, when using carbon for adsorption, the fluorine chemical flue gas is prone to form salt crystals after leaching. These crystals will gradually adhere to the inner wall of the pores of the activated carbon. As the equipment continues to operate, the crystals continue to accumulate, eventually leading to blockage of the activated carbon pores, causing its adsorption capacity to drop significantly or even completely fail.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) The fluorine chemical flue gas rapid recovery device, the connecting plate drives the adsorption chamber to rotate, so that the frequency of contact between the waste gas and the activated carbon is increased. By rotating the adsorption chamber, the frequency and time of contact between the waste gas and the activated carbon are increased, and the adsorption capacity of the activated carbon is further increased, ensuring the stability and reliability of subsequent recovery or discharge of the waste gas. At the same time, the adsorption chamber rises and falls with the roller, driving the activated carbon to shake regularly.

[0017] (2) In the fluorine chemical flue gas rapid recovery device, the supporting force of the convex seat is transmitted to the connecting plate, and the long rod provides stable support for the connecting plate, sharing the driving load of the motor. The pad is then used to reduce the direct friction between the long rod and the convex seat, reduce wear, and extend its service life. At the same time, the up and down movement of the inclined rod effectively prevents the activated carbon from getting stuck. The lifting and lowering of the inclined rod and the rotation of the adsorption chamber form a composite motion, which makes the activated carbon fully flipped in the adsorption chamber, further improving the efficiency of the contact between the exhaust gas and the activated carbon.

[0018] (3) The fluorine chemical flue gas rapid recovery device uses a steel wire in contact with the crystals and scrapes off the adhered crystals through the rotational force. The steel wire makes a circular motion along the center of the base plate, which can accurately scrape off the crystals adhered between the washing tower and the tank body to prevent the accumulation of crystals and affect the circulation of exhaust gas. At the same time, the hollow ring acts as a physical barrier, completely covering the annular groove below. By concentrating the scraped crystals in a designated area, the difficulty of subsequent unified cleaning can be reduced. The hollow ring provides a barrier to prevent the movable rod from malfunctioning during movement and affecting the normal work process.

A sealing cover is provided on the top of the tank body 5 and is fastened to the top of the tank body 5 by bolts. The convex seat 6 is coaxially arranged on the inner wall of the tank body 5, and a plurality of ventilation holes 38 are provided at the bottom of the convex seat 6; the convex seat 6 is composed of a disc 39 and a sleeve 40, the axial direction of the sleeve is vertical and coaxially fixed to the middle of the disc, and the interior of the sleeve is through-connected from top to bottom; the ventilation holes are provided on the disc; the outer peripheral wall of the disc contacts the inner peripheral wall of the tank body 5.

[0026] The curved plate 7 is fixedly mounted on the outer wall of the convex seat 6. Specifically, the curved plate 7 is fixedly mounted on the top end surface of the disc, and there are several curved plates 7 that are evenly distributed around the circumference.

[0027] An adsorption bin 8, the bottom of which is sleeved on the circumferential surface of the shaft sleeve of the convex seat 6; The roller 9 is fixedly mounted on the bottom of the adsorption bin 8; The adapter plate 10 is fixedly mounted on the top of the adsorption chamber 8, and a spoke 41 is connected between the adapter plate 10 and the top opening of the adsorption chamber 8; A T-shaped rod 11, the T-shaped rod 11 is fixedly mounted on the top of the adapter plate 10; The rotating shaft 12 is slidably mounted on the circumferential surface of the T-shaped rod 11; specifically, the T-shaped rod 11 is coaxially embedded in the interior of the rotating shaft 12, and the T-shaped rod 11 and the rotating shaft 12 can move axially relative to each other, but the T-shaped rod 11 and the rotating shaft 12 cannot rotate relative to each other, that is, the T-shaped rod 11 rotates synchronously with the rotating shaft 12.

[0028] The rotating shaft 12 rotates and penetrates the top of the sealing cover.

[0029] By rotating the adsorption bin 8, the rotating adsorption bin 8 can stir the exhaust gas inside the tank body 5, increase the activity of the exhaust gas in the tank body 5, and ensure the stability and reliability of subsequent recovery or discharge of the exhaust gas.

[0030] In an embodiment of the present invention, activated carbon is provided inside the adsorption bin 8, and the activated carbon is used to adsorb small molecular pollutants in the exhaust gas. An air flow distribution plate 42 is fixedly provided at the bottom of the adsorption bin 8, and the air flow distribution plate is used to support the activated carbon.

[0031] By increasing the frequency and time of contact between exhaust gas and activated carbon, the adsorption capacity of activated carbon can be further increased.

[0032] In an embodiment of the present invention, the roller 9 contacts the side of the convex seat 6 close to the curved plate 7, a guide groove 43 is provided on the circumferential surface of the convex seat 6, and a through hole is provided on the top of the convex seat 6, which is the top of the shaft sleeve that passes through the top and bottom.

[0033] The stability of the roller 9 ensures that the adsorption bin 8 remains stable during the rotation process.

[0034] In the embodiment of the present invention, the outer wall of the adsorption bin 8 is in contact with the inner wall of the tank body 5, and a shaft hole is opened on the top of the rotating shaft 12, and the shaft hole is used to connect the motor shaft; By making the outer wall of the adsorption chamber 8 contact with the inner wall of the tank body 5, the gap is reduced, ensuring that the exhaust gas can fully pass through the activated carbon area, thereby ensuring the stability of adsorption.

[0035] When this embodiment is working, the fluorine chemical waste gas first enters the washing tower 1, and the spray device 2 in the tower evenly sprays the alkaline absorption liquid to the packing area. The alkaline absorption liquid is evenly distributed to the packing layer to form a stable liquid film; the waste gas passes upward through the packing support plate 3 and fully contacts with the liquid film on the surface of the packing. The acidic waste gas therein is efficiently removed through the chemical absorption reaction, thereby achieving the purpose of purification; then, the waste gas continues to rise, and after the entrained acid mist droplets are separated by the demister plate 4, it enters the tank body 5 from the top of the washing tower 1; the waste gas passes through the air vents of the convex seat 6 and the adsorption chamber 8 in the tank body 5 in turn. The air flow distribution plate contacts the activated carbon in the adsorption bin 8 to further remove the residual harmful substances; at the same time, the motor drives the rotating shaft 12 to drive the T-shaped rod 11 and the connecting plate 10 to rotate synchronously, and the connecting plate 10 further drives the adsorption bin 8 to rotate with the convex seat 6 as the axis, prompting the activated carbon to move together with the adsorption bin 8, so that the frequency of contact between the exhaust gas and the activated carbon in the tank body 5 is greatly increased, ensuring that the harmful substances in the exhaust gas are more fully adsorbed; after two-stage purification, the exhaust gas is discharged from the tank body 5 for subsequent recovery, and the exhaust gas is increased by rotating the adsorption bin 8. The frequency and time of contact between the gas and the activated carbon further increase the adsorption capacity of the activated carbon and ensure the stability and reliability of the subsequent recovery or discharge of the waste gas. When the adsorption bin 8 rotates, it drives the roller 9 at the bottom to roll on the convex seat 6. The supporting force of the convex seat 6 on the roller 9 is transmitted upward to the bottom of the adsorption bin 8 through the roller 9, ensuring that the adsorption bin 8 remains stable during the rotation process; at the same time, the roller 9 intermittently contacts the curved plate 7 during the rolling process. When contact occurs, the curved plate 7 applies resistance to the roller 9, forcing the roller 9 to rise along the curved surface of the curved plate 7 until the roller 9 is lifted up. After the roller 9 rises to the highest point of the curved surface, it begins to descend and loses contact during the descent. During this process, the adsorption bin 8 intermittently reciprocates in the vertical direction as the roller 9 rises and falls, driving the activated carbon inside to shake regularly; when the adsorption bin 8 rises, the adsorption bin 8 drives the connecting plate 10 to move upward, and the connecting plate 10 drives the T-shaped rod 11 to move upward. The up and down movement can continuously change the contact surface between the activated carbon and the exhaust gas, preventing crystals in the exhaust gas from depositing in a fixed position and blocking the pores of the activated carbon, thereby maintaining the adsorption efficiency of the activated carbon and reducing the replacement frequency.

[0036] See also Figures 1-6 In another embodiment of the present invention, based on the above embodiment, an auxiliary device for improving the adsorption effect is provided inside the convex seat 6, and a processing device for cleaning crystals is provided inside the tank body 5.

[0037] In an embodiment of the present invention, the auxiliary device includes a carrying tube 21 and a lifting ring 22. The carrying tube 21 is coaxially fixedly installed in the through hole of the shaft sleeve of the convex seat 6. The lifting ring 22 slides through the inner wall of the carrying tube 21. A spring 23 is arranged between the lifting ring 22 and the carrying tube 21. The bottom of the spring 23 is supported on the limiting step 44 of the carrying tube 21, and the top of the spring 23 abuts against the bottom of the lifting ring 22.

[0038] In an embodiment of the present invention, a long rod 24 is coaxially mounted on the inner wall of the lifting ring 22, wherein the lifting ring 22 and the long rod 24 can rotate relative to each other, but the lifting ring 22 and the long rod 24 cannot move axially relative to each other, that is, the lifting ring 22 moves axially synchronously with the long rod 24.

[0039] A pad 25 is rotatably mounted on the top circumferential surface of the long rod 24, and the pad 25 moves axially synchronously with the long rod 24; a radially extending guide block 45 is fixed to the outer circumference of the lifting ring 22, and the guide block contacts the inner wall of the guide groove; a guide groove is also provided on the circumferential surface of the carrying tube 21 to facilitate the guide block to be embedded in the guide groove on the carrying tube 21 and the shaft sleeve; the top surface of the long rod 24 contacts the bottom surface of the connecting plate 10, and the pad 25 contacts the top of the shaft sleeve of the convex seat 6.

[0040] The long rod 24 provides stable support for the connecting plate 10 and shares the driving load of the motor. The pad 25 reduces the direct friction between the long rod 24 and the convex seat 6, reduces wear and tear, and extends its service life.

[0041] In an embodiment of the present invention, a sleeve 26 is fixedly installed on the outer wall of the guide block of the lifting ring 22, and an inclined rod 27 is fixedly installed on the outer circumferential surface of the sleeve 26. The inner circumferential surface of the sleeve 26 is in coaxial contact with the outer circumferential surface of the sleeve of the convex seat 6, and a vertical sliding groove 46 is provided on the circumferential surface of the bottom of the long rod 24.

[0042] The lifting and lowering of the inclined rod 27 and the rotation of the adsorption chamber 8 form a composite motion, so that the activated carbon is fully turned over in the adsorption chamber 8, further improving the contact efficiency between the exhaust gas and the activated carbon.

[0043] In an embodiment of the present invention, the processing device includes a substrate 31, which is fixedly mounted on the inner wall of the tank body 5. An annular groove 47 is provided on the top of the substrate 31, and a movable rod 32 is slidably mounted in the annular groove along the circumference. A connecting plate 33 is fixedly mounted on the circumferential surface of the top of the movable rod 32, and an axially vertical guide sleeve 48 is fixedly mounted on the inner end of the connecting plate 33. A rectangular block 49 is fixedly mounted on the inner wall of the guide sleeve. The guide sleeve is coaxially sleeved on the long rod 24, and the rectangular block is embedded in the slide groove.

[0044] In the embodiment of the present invention, a rectangular bracket 34 is fixedly mounted on the circumferential surface of the top of the movable rod 32 , and a vertical steel wire 35 is fixedly mounted on a surface of the rectangular bracket 34 away from the movable rod 32 .

[0045] By making a circular motion along the center of the base plate 31, the steel wire 35 can accurately scrape off the crystals adhering to the space between the washing tower 1 and the tank body 5, thereby preventing the accumulation of the crystals from affecting the flow of the exhaust gas.

[0046] In an embodiment of the present invention, an axially vertical arc plate 36 is fixedly installed on the outer wall of the rectangular bracket 34, and a hollow ring 37 covering the annular groove is coaxially rotatably installed on the top of the base plate 31. A circular hole is opened on the top of the hollow ring 37 to facilitate the movable rod 32 to pass upward along the circular hole, and the bottom end of the movable rod 32 is located in the annular groove.

[0047] By providing a barrier with the hollow ring 37, the movable rod 32 is prevented from malfunctioning during movement, thereby preventing the normal working process from being affected.

[0048] When the connecting plate 10 is in operation, the long rod 24 in contact with its bottom rotates synchronously under the action of friction, and the supporting force of the convex seat 6 on the pad 25 is transmitted to the connecting plate 10 through the long rod 24, thereby sharing the load of the motor-driven rotating shaft 12 and reducing energy consumption; when the connecting plate 10 moves up, the compressed spring 23 recovers and pushes the lifting ring 22 to move up, and the lifting ring 22 drives the long rod 24 to move up, so that the long rod 24 always keeps in contact with the connecting plate 10, and at the same time, the long rod 24 further drives the pad 25 to move up, so that the pad 25 is separated from the convex seat 6; when the connecting plate 10 moves down, the connecting plate 10 pushes the long rod 24 to move down, and the long rod 24 drives the pad 25 to move down and re-contact the convex seat 6, and at the same time, the long rod 24 drives the lifting ring 22 to move down, and the lifting ring 22 compresses the spring 23 during movement, causing it to deform, and through the long rod 24 The connecting plate 10 is provided with stable support, sharing the driving load of the motor, and the pad 25 is used to reduce the direct friction between the long rod 24 and the convex seat 6, thereby reducing wear and extending its service life. When the adsorption bin 8 rotates, the inclined rod 27 is in continuous contact with the activated carbon and produces a blocking effect. The activated carbon constantly changes its position under the obstruction of the inclined rod 27, ensuring that the activated carbon can be adsorbed, avoiding local accumulation of activated carbon or contact with exhaust gas in a fixed area; when the lifting ring 22 reciprocates, it drives the sleeve 26 to rise and fall synchronously, and the sleeve 26 further drives the inclined rod 27 to move up and down. The up and down movement of the inclined rod 27 prevents it from staying in the same position for a long time when blocking the activated carbon, effectively preventing the activated carbon from getting stuck. The lifting and lowering of the inclined rod 27 and the rotation of the adsorption bin 8 form a composite motion, which makes the activated carbon fully flipped in the adsorption bin 8, further improving the efficiency of contact between the exhaust gas and the activated carbon. When the long rod 24 rotates, it drives the connecting plate 33 to rotate synchronously, and the connecting plate 33 further drives the movable rod 32 to make a circular motion along the annular groove. The movable rod 32 drives the rectangular bracket 34 to rotate synchronously, and the rectangular bracket 34 further drives the steel wire 35 to rotate. During the rotation process, the steel wire 35 contacts the crystals between the washing tower 1 and the tank body 5, and uses the rotational force to scrape them off to prevent the accumulation of crystals from affecting the flow of exhaust gas. The steel wire 35 makes a circular motion along the center of the base plate 31, which can accurately scrape off the crystals between the washing tower 1 and the tank body 5 to prevent the accumulation of crystals from affecting the flow of exhaust gas. When the rectangular bracket 34 rotates, it drives the arc plate 36 to rotate synchronously, and the concave surface of the arc plate 36 forms a guide The channel allows the crystals scraped off by the steel wire 35 to fall to the designated area between the base plate 31 and the tank body 5 under the action of gravity, preventing the crystals from splashing onto the surface of the defogger plate 4 and avoiding the risk of secondary blockage; and when the movable rod 32 rotates, it drives the hollow ring 37 to rotate synchronously. The hollow ring 37 acts as a physical barrier, completely covering the annular groove below, so that the hollow ring 37 intercepts the falling crystals during rotation, preventing the crystals from entering the annular groove and causing a malfunction when the movable rod 32 rotates. By concentrating the scraped crystals in the designated area, the difficulty of subsequent unified cleaning can be reduced, and the hollow ring 37 is used to provide a barrier to prevent the movable rod 32 from malfunctioning during movement and affecting the normal work process.
