Description

Technical Field

[0001] The present invention relates to the technical field of scrubbers, and particularly relates to a combined spray device for a scrubber and a scrubber. Background Art

[0002] A scrubber is a new type of gas purification and treatment equipment. It is improved on the basis of a floating packing layer gas purifier and is widely used in the pretreatment of industrial waste gas purification, dust removal, etc., and has a good purification effect. For the coal gasification process, gas washing is inevitable, and this unit operation is used in any coal gasification technology. Since its working principle is similar to the washing process, it is named a scrubber, and the scrubber is similar to a distillation column. Since the scrubber is a device for rough separation. The scrubber is suitable for separating a mixed gas containing a small amount of dust, and each component will not react, and the product should be easily liquefied, and impurities such as dust are not easily liquefied or solidified. When the mixed gas is introduced into the scrubber from the middle of the scrubber, since there is a product component liquid between the trays, part of the product component gas is evaporated while liquefying, and the impurities, since they cannot be liquefied or solidified, will be fixed by the product component liquid when passing through the tray with liquid present, producing a washing effect; For example, the invention patent with the publication number CN108404567B and the name "Scrubber" includes an inner main tower, a middle primary washing tower and an outer reflux tower; the middle primary washing tower surrounds the outside of the inner main tower, and the outer reflux tower surrounds the outside of the middle primary washing tower; an air inlet leading to the outside of the scrubber is provided at a position slightly below the middle of the middle primary washing tower; a bottom liquid of the primary washing tower is provided below the air inlet inside the middle primary washing tower; a sewage outlet is provided at a position close to the bottom of the side wall of the middle primary washing tower; a primary washing packing layer and a primary washing spray device are provided above the air inlet inside the middle primary washing tower; an adsorption cotton felt is provided in the middle of the outer reflux tower; a main tower packing layer, a main tower spray device and a demisting layer are successively provided above the gas passage inside the inner main tower; an air outlet is provided at the top of the inner main tower, and it mainly washes and purifies the waste gas through the main tower packing layer.

[0003] When using a scrubber for waste gas washing and purification, the waste gas is transported into the scrubber from below the packing layer, and the rising waste gas contacts the water film on the packing layer to preliminarily purify the waste gas. As shown in the above patent, the packing layer of some existing scrubbers for waste gas treatment is easily blocked by sundries after long-term use, resulting in a decrease in the air circulation efficiency inside the device and affecting the treatment effect of the scrubber.

Detailed implementation manners

[0019] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below with reference to the accompanying drawings.

[0020] Please refer to Figure 1-13, A combined spray device for a scrubbing tower, comprising a plurality of spray pipes 13, and further comprising a support ring 41 fixedly arranged inside the scrubbing tower and a connecting pipe rack 21. A packing cage 16 is arranged on the support ring 41. A plurality of rotating abutting plates 161 are fixedly arranged at both ends of the packing cage 16. Four high-pressure flushing pipes 27 for flushing the packing cage 16 are fixedly communicated with the outer peripheral surface of the connecting pipe rack 21. A sliding water pipe 25 is slidably arranged inside the connecting pipe rack 21. One end of the sliding water pipe 25 is fixedly communicated with a telescopic water pipe 23. A water pump 5 for driving the sliding water pipe 25 to move is fixedly arranged at the end of the telescopic water pipe 23. Two abutting assemblies and two limiting assemblies are arranged inside the support ring 41. Each abutting assembly abuts against the packing cage 16. Two flipping toothed plates 61 for driving the abutting assemblies to flip are slidably arranged on the support ring 41. A transmission ring 31 for driving the flipping toothed plate 61 to move is fixedly arranged at the bottom of the sliding water pipe 25; the water pump 5 can adjust the pressure and flow rate. The limiting assembly is used to limit the packing cage 16 to prevent the packing cage 16 from flipping randomly. The packing cage 16 is filled with Raschig ring packing or hollow ball packing for washing waste gas. Four support rods 28 are fixedly arranged on the support ring 41. Each support rod 28 is fixedly connected to each high-pressure flushing pipe 27 in a one-to-one correspondence. The high-pressure flushing pipe 27 is supported by the support rod 28, and then the connecting pipe rack 21 is supported. A flipping groove 17 is formed on the side wall of the packing cage 16. The two abutting assemblies are symmetrically arranged inside the flipping groove 17. The packing cage 16 is supported by the abutting assembly abutting against the inner wall of the flipping groove 17. When the abutting assembly flips, the packing cage 16 also flips accordingly. A plurality of high-pressure nozzles 29 are fixedly arranged on each high-pressure flushing pipe 27. The high-pressure nozzles 29 are inclined. Each rotating abutting plate 161 is inclined. A plurality of connecting rods 32 are fixedly arranged at the bottom of the sliding water pipe 25. A plurality of sliding grooves 22 for the connecting rods 32 to slide are formed on the outer peripheral surface of the connecting pipe rack 21. One end of each connecting rod 32 away from the sliding water pipe 25 is fixedly connected to the transmission ring 31. Four water outlets 251 are formed at the bottom of the sliding water pipe 25. A rubber sleeve 252 is fixedly arranged at the bottom of the sliding water pipe 25. The outer wall of the sliding water pipe 25 abuts against the inner wall of the connecting pipe rack 21. The rubber sleeve 252 is used to prevent the liquid inside the sliding water pipe 25 from leaking out. A buffer box 12 is fixedly arranged on the connecting pipe rack 21. Each spray pipe 13 is fixedly communicated with the buffer box 12. Four spray through holes 15 communicated with the connecting pipe rack 21 are formed on the inner wall of the buffer box 12. A plurality of spray heads 14 are fixedly arranged on each spray pipe 13.

[0021] In the initial state, each water outlet 251 of the sliding water pipe 25 is in one-to-one correspondence and communication with each spray through hole 15 of the buffer box 12. The liquid can be normally sprayed out from the spray pipe 13 through the water pump 5, so as to wash the waste gas. When it is necessary to clean the packing in the packing cage 16, the water pressure in the sliding water pipe 25 is increased through the water pump 5. At this time, the spray pipe 13 cannot release the water pressure in the sliding water pipe 25 in time, so that the telescopic water pipe 23 extends. At this time, the sliding water pipe 25 moves in a direction away from the telescopic water pipe 23. The sliding water pipe 25 moves with the increase of the liquid pressure. When the sliding water pipe 25 moves, it drives the transmission ring 31 to move downward through the connecting rod 32. When the transmission ring 31 moves downward, it first drives the limit component to release the limit of the packing cage 16, and then the transmission ring 31 abuts against the flipping tooth plate 61 and pushes the flipping tooth plate 61 downward. When the flipping tooth plate 61 moves downward, it drives the abutting component to flip, so as to drive the packing cage 16 to flip, so that the packing in the upper and lower parts of the packing cage 16 is transposed. The height of the support rod 28 is greater than the radius of the cross section of the packing cage 16 to prevent the high-pressure washing pipe 27 from hindering the flipping of the packing cage 16. When the packing cage 16 flips, the water outlet 251 of the sliding water pipe 25 is communicated with the high-pressure washing pipe 27. By adjusting the flow rate of the water pump 5, the water pressure in the sliding water pipe 25 is increased. The pressurized liquid is sprayed on the packing cage 16 through the high-pressure nozzle 29 on the high-pressure washing pipe 27, so as to wash the packing in the packing cage 16. The outermost high-pressure nozzle 29 of each high-pressure washing pipe 27 will spray high-pressure water on the rotating abutting plate 161. When the rotating abutting plate 161 is pushed by the high-pressure water, it will drive the packing cage 16 to rotate, thus generating centrifugal force. The impurities and liquid that are not washed off on the packing are thrown out by the centrifugal force, greatly increasing the cleaning effect.

[0022] In another embodiment of the present invention: an unlocking groove 44 is formed in the support ring 41, and the limiting component includes two sealing plates 42 slidably disposed in the unlocking groove 44. A blocking plate 45 is fixedly disposed on the inner wall of each sealing plate 42, and a locking plate 43 is fixedly disposed on each blocking plate 45. An activity groove 421 is formed on the side of each sealing plate 42 away from the blocking plate 45, and an abutting rod 422 is fixedly disposed in each activity groove 421. Two unlocking frames 51 are slidably disposed on the support ring 41, and each abutting rod 422 is correspondingly disposed in each unlocking frame 51. In the initial state, the blocking plates 45 on each sealing plate 42 are all in contact with the outer peripheral surface of the packing cage 16. At this time, the locking plates 43 on each blocking plate 45 are all inserted into the flipping groove 17 on the packing cage 16. By the abutting of the locking plate 43 against the inner wall of the flipping groove 17, the packing cage 16 is prevented from flipping. Each blocking plate 45 is made of rubber material. By the abutting of the rubber material blocking plate 45 against the packing cage 16, the unwashed waste gas can be prevented from passing through the packing cage 16. When the unlocking frame 51 moves downward, the sealing plate 42, the blocking plate 45 and the locking plate 43 are driven by the abutting rod 422 to move away from the packing cage 16, so as to pull out the locking plate 43 from the flipping groove 17 on the packing cage 16. At this time, the packing cage 16 can be flipped. When the unlocking frame 51 moves upward, the sealing plate 42, the blocking plate 45 and the locking plate 43 are driven by the abutting rod 422 to move towards the packing cage 16, so that the locking plate 43 is inserted into the flipping groove 17 on the packing cage 16, and the limiting of the packing cage 16 is completed.

[0023] In another embodiment of the present invention: a first buffer groove 511, a driving groove 512 and a second buffer groove 513 are formed on each unlocking frame 51; the first buffer groove 511, the driving groove 512 and the second buffer groove 513 on the same unlocking frame 51 communicate with each other; in the initial state, each abutting rod 422 is correspondingly located in each second buffer groove 513, as Figure 11 shown. When it is necessary to flip the packing cage 16, move the unlocking frame 51 downward, drive the abutting rod 422 to move leftward through the driving groove 512, so that the sealing plate 42 moves away from the packing cage 16, and then flip the packing cage 16. After the packing cage 16 is flipped, move the unlocking frame 51 upward, and through the cooperation of the driving groove 512 and the abutting rod 422, the sealing plate 42 moves towards the packing cage 16, so that each locking plate 43 is inserted into the flipping groove 17.

[0024] In another embodiment of the present invention: The abutting assembly includes two flipping rods 62 rotatably arranged in the support ring 41. At one end of each flipping rod 62 away from the support ring 41, an abutting arc plate 67 is fixedly arranged. Each abutting arc plate 67 abuts against the packing cage 16. On each flipping rod 62, a fixing ring 63 is fixedly arranged. On each fixing ring 63, three pawls 66 are fixedly arranged. On the outer peripheral surface of each fixing ring 63, a flipping gear ring 64 meshing with the flipping gear plate 61 is sleeved. On the inner ring of each flipping gear ring 64, a number of ratchet teeth 65 cooperating with the pawls 66 are fixedly arranged; A torsion spring (not marked in the figure) is arranged in each pawl 66. Through the cooperation of the flipping rod 62 and the abutting arc plate 67, the packing cage 16 is supported. Each abutting arc plate 67 is located in the flipping groove 17. The inner side of the arc-shaped abutting arc plate 67 abuts against the inner wall of the flipping groove 17 to prevent the packing cage 16 from falling off the support ring 41 when it flips. Each flipping gear plate 61 is arranged on the same side of the flipping gear ring 64, as Figure 12 shown. When the flipping gear plate 61 moves downward, it drives the flipping gear ring 64 to rotate. Through the cooperation of the ratchet teeth 65 and the pawls 66, the fixing ring 63 is driven to rotate. At this time, the corresponding flipping rod 62 rotates, thereby driving the abutting arc plate 67 to rotate, and further driving the packing cage 16 to rotate. When the flipping gear plate 61 moves upward, it drives the corresponding flipping gear ring 64 to rotate. At this time, due to the torsion spring (not marked in the figure) on the pawl 66, the fixing ring 63 does not rotate with the flipping gear ring 64, so that the packing at the bottom layer of the packing cage 16 that first contacts the waste gas flips to the upper layer, and thus each layer of packing inside the packing cage 16 is fully utilized.

[0025] In another embodiment of the present invention: On one side of each abutting arc plate 67 away from the flipping rod 62, two second balls 69 are movably arranged. On both sides of each abutting arc plate 67, two first balls 68 are movably arranged; The abutting arc plate 67 abuts against the upper and lower walls of the flipping groove 17 through the first balls 68 on both sides, and the abutting arc plate 67 abuts against the inner peripheral surface of the flipping groove 17 through the two second balls 69. The first balls 68 and the second balls 69 can reduce the friction between the abutting arc plate 67 and the packing cage 16, facilitating the rotation of the packing cage 16.

[0026] In another embodiment of the present invention: A push rod 52 is fixedly arranged on each unlocking frame 51, a return pull rod 53 is fixedly arranged on each push rod 52 and each flipping tooth plate 61, and each return pull rod 53 is slidably connected with the transmission ring 31; A limiting plate 54 is fixedly arranged at one end of each return pull rod 53 far away from the support ring 41. When the transmission ring 31 moves downward, it first abuts against the push rod 52 and drives the push rod 52 to move downward. When the push rod 52 drives the unlocking frame 51 to move downward and pulls out the locking plate 43 from the flipping groove 17, the transmission ring 31 abuts against the flipping tooth plate 61 and drives the flipping tooth plate 61 to move downward, so as to cause the packing cage 16 to flip. When the flipping tooth plate 61 moves downward, the abutting rod 422 is prevented from obstructing the downward movement of the flipping tooth plate 61 through the first buffer groove 511. The return pull rods 53 on each push rod 52 are shorter than the return pull rods 53 on each flipping tooth plate 61. After the packing cage 16 finishes flipping, the transmission ring 31 is moved upward, and each return pull rod 53 is driven to move upward through each limiting plate 54. When the transmission ring 31 moves upward, it first drives the two unlocking frames 51 to move upward, thereby driving the two locking plates 43 to be inserted into the flipping groove 17 to fix the packing cage 16. Continuing to move the transmission ring 31 upward drives the two flipping tooth plates 61 to move upward, thereby facilitating the next flipping of the packing cage 16.

[0027] In another embodiment of the present invention: Four communicating pipes 26 are fixedly communicated with the outer peripheral surface of the connecting pipe rack 21, and one end of each communicating pipe 26 away from the connecting pipe rack 21 is fixedly communicated with a high-pressure flushing pipe 27; One-way valves (not marked in the figure) are fixedly arranged at one end of each high-pressure flushing pipe 27 and each communicating pipe 26 close to the connecting pipe rack 21. Through the one-way valves (not marked in the figure), liquid can only enter the communicating pipe 26 and the high-pressure flushing pipe 27 from the sliding water pipe 25, and cannot flow back from the high-pressure flushing pipe 27 and the communicating pipe 26 into the connecting pipe rack 21. When the bottom water outlet 251 of the sliding water pipe 25 moves downward to the water inlet position of the communicating pipe 26 as the liquid pressure increases, each water outlet 251 on the sliding water pipe 25 communicates with each communicating pipe 26 in a one-to-one correspondence. The high-pressure water in the sliding water pipe 25 is discharged into the high-pressure flushing pipe 27 through each communicating pipe 26. At this time, the transmission ring 31 has not yet abutted against the ejector rod 52. The high-pressure water in the high-pressure flushing pipe 27 flushes the upper packing of the unflipped packing cage 16 and drives the packing cage 16 to rotate, so as to clean the upper packing of the packing cage 16. After the upper layer of the packing cage 16 is cleaned for a period of time, the water pressure in the sliding water pipe 25 is increased again through the water pump 5, so that the sliding water pipe 25 drives the transmission ring 31 to continue to move downward. During the movement of the transmission ring 31, it abuts against the ejector rod 52 and the flipping tooth plate 61 and drives the packing cage 16 to flip. The sliding water pipe 25 is a cylindrical tube with one end closed. When the packing cage 16 finishes flipping, the bottom wall of the sliding water pipe 25 moves to the inner bottom wall of the connecting pipe rack 21. At this time, the water outlets 251 of the sliding water pipe 25 communicate with the water inlets of the high-pressure flushing pipes 27 in a one-to-one correspondence. The pressure in the sliding water pipe 25 is released through each high-pressure flushing pipe 27. Since the pressure applied by the water pump 5 to the sliding water pipe 25 is greater than the pressure released by the high-pressure flushing pipe 27, the sliding water pipe 25 always abuts against the inner bottom wall of the connecting pipe rack 21. At this time, the liquid ejected from the high-pressure flushing pipe 27 has a greater speed, so that the flipped packing cage 16 is flushed more thoroughly, and thus the packing that first contacts the waste gas is cleaned sufficiently.

[0028] In another embodiment of the present invention: Two first through grooves 411 for the unlocking frame 51 to move and two second through grooves 412 for the fixed flipping tooth plate 61 to move are provided on the support ring 41. Four movable boxes 413 are fixedly arranged on one side of the support ring 41 away from the flipping tooth plate 61; The two first through grooves 411 and the two second through grooves 412 at the bottom of the support ring 41 are blocked by the four movable boxes 413, so as to prevent waste gas from flowing from the first through groove 411 and the second through groove 412 to the upper part of the packing cage 16.

[0029] In another embodiment of the present invention: One end of the telescopic water pipe 23 away from the sliding water pipe 25 is fixedly provided with a connecting water pipe 8. A demisting net 10 is fixedly provided on the connecting water pipe 8. One end of the sliding water pipe 25 close to the connecting water pipe 8 is fixedly provided with a fixing plate 241. A spring 24 is fixedly provided between the fixing plate 241 and the demisting net 10. The telescopic water pipe 23 is fixedly connected to the connecting water pipe 8 through a water pump 5. When the water pressure in the sliding water pipe 25 is increased by adjusting the pressure of the water pump 5, the sliding water pipe 25 moves away from the demisting net 10, and the telescopic water pipe 23 extends. At this time, the spring 24 is stretched. When the water pump 5 stops injecting water into the sliding water pipe 25, the sliding water pipe 25 is driven by the spring 24 to move upward, so that the transmission ring 31 drives the flipping tooth plate 61 and the unlocking frame 51 to move upward. At this time, the telescopic water pipe 23 contracts and resets.

[0030] In another embodiment of the present invention: A scrubbing tower includes the scrubbing tower combined spraying device according to any one of claims 1-9, and further includes a tower body 1. An air inlet pipe 3 is fixedly provided on the tower body 1. A circulating water tank 11 is fixedly provided on the inner bottom wall of the tower body 1. The water pump 5 is fixedly provided on the top wall of the tower body 1. The water inlet end of the water pump 5 is fixedly provided with a circulating water pipe 4. One end of the circulating water pipe 4 away from the water pump 5 is inserted into the circulating water tank 11. The liquid in the circulating water tank 11 is pumped into the sliding water pipe 25 through the water pump 5 and the circulating water pipe 4. The liquid passes through the packing cage 16 and then falls into the circulating water tank 11 again, thereby completing the recycling of the liquid. Both the support ring 41 and the demisting net 10 are fixedly connected to the inner wall of the tower body 1. The connecting water pipe 8 is fixedly connected to the inner top wall of the tower body 1. An exhaust pipe 6 for exhausting gas is fixedly provided at the top of the tower body 1. Two reset ropes 7 are fixedly provided on one side of the transmission ring 31 away from the support ring 41.

Two fixing nails 713 are fixedly provided on the outer peripheral surface of the tower body 1. Two rubber tubes 711 are fixedly provided on the side wall of the tower body 1. One end of each reset rope 7 away from the transmission ring 31 passes through the rubber tube 711 and is fixedly connected to the hanging ring 712. The rubber tube 711 is in close contact with the reset rope 7, thereby preventing gas from flowing out of the rubber tube 711. When it is not necessary to wash the packing cage 16, pull down the reset rope 7 to make the transmission ring 31 drive the sliding water pipe 25 to move upward, so that each water outlet 251 of the sliding water pipe 25 is aligned with each spraying through hole 15 one by one. At this time, hang each hanging ring 712 on each fixing nail 713 one by one, thereby fixing the positions of the sliding water pipe 25 and the transmission ring 31. The inside of the scrubbing tower can be conveniently observed through the observation and maintenance window 2. The waste gas enters the tower body 1 through the air inlet pipe 3.

[0031] Working principle: Through the cooperation of the reset rope 7, the hanging ring 712, and the fixing nail 713, the water outlet 251 of the sliding water pipe 25 is aligned with the spray through hole 15 of the buffer box 12 one by one. The liquid in the circulating water tank 11 is pumped into the sliding water pipe 25 by the water pump 5 and sprayed into the packing cage 16 through the spray pipe 13. When it is necessary to clean the packing in the packing cage 16, the hanging ring 712 is removed from the fixing nail 713, increasing the pressure of the water pump 5 and thus increasing the pressure in the sliding water pipe 25. After the pressure in the sliding water pipe 25 increases, the spray pipe 13 cannot release the pressure in the sliding water pipe 25. At this time, the sliding water pipe 25 moves downward. As the pressure in the sliding water pipe 25 increases, the telescopic water pipe 23 elongates, and at this time the spring 24 is stretched. The water outlet 251 of the sliding water pipe 25 is first connected to the connecting pipe 26 during the downward movement. At this time, the high-pressure water in the sliding water pipe 25 enters each high-pressure flushing pipe 27 through the connecting pipe 26 and is ejected through the high-pressure nozzles 29 on each high-pressure flushing pipe 27. A part of the ejected high-pressure water is sprayed on the packing cage 16 to flush the packing in the packing cage 16, and the other part is sprayed on the rotating abutting plate 161 to push the packing cage 16 to rotate, so that the dust and liquid staying in the packing gaps are thrown out. After a certain period of time, the pressure of the water pump 5 is increased again. At this time, each connecting pipe 26 cannot completely release the pressure in the sliding water pipe 25, so that the sliding water pipe 25 moves downward again. When the sliding water pipe 25 moves downward for the second time, the transmission ring 31 fixedly connected to it abuts against the ejector rod 52. When the sliding water pipe 25 moves downward for the second time, it pushes the unlocking frame 51 to move downward first, so as to pull out the locking plate 43 in the packing cage 16. At this time, the packing cage 16 can be turned over. When the transmission ring 31 continues to move downward with the sliding water pipe 25, it abuts against the turning tooth plate 61 and pushes the turning tooth plate 61 downward. When the turning tooth plate 61 moves downward, it drives the turning rod 62 to rotate through the turning tooth ring 64, and then drives the packing cage 16 to turn over. When the packing cage 16 finishes turning over, the sliding water pipe 25 abuts against the inner bottom wall of the connecting pipe frame 21. At this time, the water outlet 251 of the sliding water pipe 25 is connected to each high-pressure flushing pipe 27. The high-pressure water is sprayed on the turned-over packing cage 16 through the high-pressure nozzles 29 of the high-pressure flushing pipe 27 and drives the packing cage 16 to rotate again. Since the water pressure in the sliding water pipe 25 is greater after the packing cage 16 is turned over, the impact force of the high-pressure water sprayed on the packing cage 16 is greater, which can fully flush the packing that first contacts the waste gas, and the high-pressure water with a greater impact force can push the packing cage 16 to rotate more quickly, so as to deeply clean the packing at different positions of the packing cage 16.
