Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water washing tower, in particular to a MTBE water washing tower group structure. BACKGROUND

[0002] The MTBE water washing tower is a key equipment in the production process of MTBE (methyl tert-butyl ether), and a large amount of ether post carbon four mixture is generated in the MTBE preparation process. The MTBE water washing tower is mainly used for removing residual methanol in the ether post carbon four mixture. The filtered ether post carbon four mixture enters the water washing tower from the bottom through a pressurizing pump for water washing.

[0003] The ether post carbon four mixture is in a gaseous state under pressure, and the overall pressure of the water washing tower is greater than the external pressure. The ether post carbon four mixture moves upward as a light phase under the driving of the pressure difference, and water flows downward from the top as a heavy phase. In the countercurrent contact process (full mixing and contact through the liquid layer on the surface of the filler or the tray), methanol diffuses from the ether post carbon four mixture to the water phase due to its strong hydrophilicity. The water flowing from the top becomes a methanol-rich aqueous solution after absorbing methanol, and is discharged from the bottom. The ether post carbon four mixture after removing the residual methanol is discharged from the top.

[0004] In the process of water washing of the ether post carbon four mixture in the water washing tower, the water washing effect of the ether post carbon four mixture is affected by two aspects. On the one hand, the flow path of the ether post carbon four mixture in the water washing tower is usually a straight upward flow path, and the residence time of the ether post carbon four mixture in the water washing tower is insufficient, which leads to insufficient contact between the residual methanol in the ether post carbon four mixture and water, affecting the water washing effect of the ether post carbon four mixture. On the other hand, during the water washing of the ether post carbon four mixture, plugging occurs on the filler, which needs to be cleaned regularly to ensure the passing rate of the ether post carbon four mixture at the filler position, so that the ether post carbon four mixture can fully mix with water at the filler position. Since the filler cleaning is generally periodic, at the end of the time period between two cleaning periods, there is a part of plugging on the filler, which leads to a low passing rate of the ether post carbon four mixture for a period of time, resulting in insufficient contact between the residual methanol in the ether post carbon four mixture and water, affecting the water washing effect of the ether post carbon four mixture.

[0034] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] like Figure 1 and Figure 2 As shown, an MTBE water washing tower structure includes a tower body 1. A distributor 2 is fixedly connected to the bottom of the tower body 1, and a distributor 3 is fixedly and continuously connected to the top of the tower body 1. Multiple packing materials 4 are evenly distributed in the vertical direction inside the tower body 1. The top of the tower body 1 is connected to a discharge pipe for outputting the water-washed post-etherified C4 mixture. A collection chamber for collecting methanol-water solution is provided at the bottom of the tower body 1. A knocking mechanism 5 for cleaning blockages of the packing materials 4 is provided inside the tower body 1. An adjustment mechanism 6 for adjusting the flow path of the post-etherified C4 mixture is provided inside the tower body 1. A linkage mechanism 7 for linkage between the knocking mechanism 5 and the adjustment mechanism 6 is provided between the knocking mechanism 5 and the adjustment mechanism 6.

[0036] like Figure 1 and Figure 3 As shown, the striking mechanism 5 includes a striking element 51 installed inside the tower body 1 to prevent the packing 4 from clogging. An adjusting element 53 for adjusting the impact force of the striking element 51 is correspondingly provided on the outer circumferential surface of the tower body 1. Two symmetrical hydraulic cylinders 52 are fixedly connected to the bottom of the outer circumferential surface of the tower body 1 through a support frame.

[0037] like Figure 1and Figure 3 As shown, the adjustment mechanism 6 includes a fixed baffle 61 rotatably connected to the inner circumferential surface of the tower body 1. The fixed baffle 61 is rotatably connected to the inner circumferential surface of the tower body 1 via two connecting shafts. The output shaft of the first drive motor is fixedly connected to one of the connecting shafts and drives the fixed baffle 61 to deflect inside the tower body 1. The rotatable connection position between the output shaft of the first drive motor and the tower body 1 is sealed. The first drive motor is a waterproof motor and is connected to an external power source via a waterproof wire (not shown in the figure). The fixed baffle 61 has multiple fan-shaped gaps arranged in a circumferential array. The fixed baffle 61 is located below the striking member 51. A movable baffle 62 is rotatably connected to the upper surface of the fixed baffle 61. The fixed baffle 61 and the movable baffle 62 rotate coaxially. A second drive motor is fixedly installed on the lower surface of the movable baffle 62. The second drive motor is a waterproof and explosion-proof motor and is connected to a waterproof wire (not shown in the figure). (Not shown) Connected to an external power source, the output shaft of the second drive motor passes through the fixed baffle 61 and is fixedly connected to the lower surface of the moving baffle 62. A protective shell is provided at the location of the second drive motor to protect it from damage during normal operation. The protective shell serves to waterproof the second drive motor. The moving baffle 62 also has multiple fan-shaped gaps arranged in a circular array. When the fan-shaped gaps on the fixed baffle 61 and the moving baffle 62 are completely misaligned, the fixed baffle 61 and the moving baffle 62 form a complete closed disk. The etherified C4 mixture cannot pass through the fixed baffle 61 and the moving baffle 62. Conversely, the larger the overlapping area of ​​the two fan-shaped gaps, the greater the flow rate of the etherified C4 mixture through the fixed baffle 61 and the moving baffle 62. A drainage component 64 for drainage is provided on the upper surface of the moving baffle 62, and a shielding component 63 is provided on the circumferential surface of the fixed baffle 61.

[0038] like Figure 3 As shown, the striking component 51 includes a striking part 511 slidably connected to the inner wall of the tower body 1 and located below the packing 4 for striking the packing 4. The striking part 511 is divided into an inner ring and an outer ring, and the inner and outer rings are concentric. It should be noted that different numbers of concentric rings can be selected for combination according to actual needs, so that the striking part 511 can strike the lower surface of the packing 4 evenly and comprehensively. Multiple evenly distributed support rods are fixedly connected between the outer circumferential surface of the inner ring and the inner circumferential surface of the outer ring. Multiple through slots distributed in a circular array are opened on the inner circumferential surface of the tower body 1 at the position corresponding to the striking part 511. The outer circumferential surface of the outer ring of the striking part 511 is slidably connected to the through slot in the vertical direction by a connecting piece at the position corresponding to the through slot.

[0039] When the C4 mixture after etherification is washed with water, the fixed baffle 61 is driven to deflect by its corresponding drive motor, and performs a reciprocating motion from horizontal to tilted at a certain angle and then back to horizontal. The deflection directions of two adjacent fixed baffles 61 are opposite. When all the fixed baffles 61 are adjusted to the tilted state, the flow path of the C4 mixture after etherification changes from a straight line to a curve.

[0040] It should be noted that the rotation speed of the driving motor one drives the rotation of the fixed baffle 61 is slow, and it takes a long time for the fixed baffle 61 to complete one reciprocating action from horizontal to a certain angle of inclination and then back to horizontal.

[0041] Then water is transported to the inside of the distributor two 3, and the water is uniformly distributed in the inside of the tower body 1 by the distributor two 3 and flows downward, and then the ether post carbon four mixture after filtering impurities is transported to the distributor one 2 by the pressurizing pump and is uniformly distributed in the inside of the bottom end of the tower body 1, the ether post carbon four mixture flows upward in the inside of the tower body 1 and contacts the water flowing downward at the position of the filler 4 to perform water washing mixing, the ether post carbon four mixture after water washing continues to move upward and is output from the inside of the tower body 1 to the next process through the discharge pipe at the top end of the tower body 1, and the methanol aqueous solution obtained after water washing flows downward and is collected in the collection bin at the bottom end of the tower body 1, and then is discharged to the outside of the tower body 1.

[0042] When the ether post carbon four mixture flows upward, the driving motor one adjusts the deflection angle of the fixed baffle 61, when the fixed baffle 61 gradually changes from inclination to horizontal, at this time the driving motor two starts to drive the movable baffle 62 to rotate on the fixed baffle 61, before the fixed baffle 61 completely changes to horizontal, the fan-shaped hollow part regions on the fixed baffle 61 and the movable baffle 62 are overlapped to ensure that the ether post carbon four mixture flows normally upward, when the fixed baffle 61 is inclined again, at this time the driving motor two drives the movable baffle 62 to reverse on the fixed baffle 61, so that the fan-shaped hollow regions on the fixed baffle 61 and the movable baffle 62 are completely staggered, the fixed baffle 61 and the movable baffle 62 form a complete disc, at this time the ether post carbon four mixture cannot pass through the fixed baffle 61 and needs to flow along the inclined path of the fixed baffle 61.

[0043] The fixed baffle 61 generates a downward pulling force on the knocking part 511 through the linkage mechanism 7 in the deflection process, after the knocking part 511 moves downward to the position of the adjusting part 53, at this time the adjusting part 53 limits the knocking part 511, the knocking part 511 stops moving downward, then the linkage mechanism 7 cancels the pulling force on the knocking part 511, the knocking part 511 quickly resets to knock the filler 4, the filler 4 vibrates to vibrate and separate the blockage thereon, and the filler 4 is dredged to ensure the passing amount of the ether post carbon four mixture.

[0044] As Figure 3 , Figure 4 and Figure 5As shown, the shielding piece 63 comprises a fixed ring 631 fixedly connected to the outer circumferential surface of the fixed baffle 61, the upper surface of the fixed ring 631 is uniformly provided with a plurality of connecting frames 634, the connecting frame 634 is hingedly connected with a shielding plate 633 at one end away from the fixed ring 631, a torsion spring I (not shown in the figure) is arranged between the shielding plate 633 and the connecting frame 634, the torsion spring I is made of rust-proof and corrosion-resistant material, for example, stainless steel spring and special alloy spring, when the fixed baffle 61 is in a horizontal state, the shielding plate 633 and the connecting frame 634 are in a vertical state and the torsion spring is in a tightened state, the outer circumferential surface of the fixed ring 631 is fixedly connected with a sealing gasket 632, the connecting frames 634 are distributed on one half region of the upper surface of the fixed ring 631, the position of the downward rotation of the movable baffle 62 is the position of the distribution region of the connecting frames 634, the other half region of the outer circumferential surface of the fixed ring 631 is fixedly connected with the sealing gasket 632, and the distribution regions of the connecting frames 634 on the adjacent two fixed rings 631 are staggered.

[0045] In specific use, when the fixed baffle 61 begins to tilt, at this time, the side of the fixed baffle 61 which tilts downward gradually moves away from the inner circumferential surface of the tower body 1, and the fixed baffle 61 drives the shielding plate 633 to move away from the inner circumferential surface of the tower body 1, since the torsion spring I between the shielding plate 633 and the connecting frame 634 is in a tightened state when the fixed baffle 61 is in a horizontal state, the fixed baffle 61 tilts, under the action of the elastic force of the torsion spring I itself, the bottom end of the shielding plate 633 always abuts against the inner circumferential surface of the tower body 1 while the top end of the shielding plate 633 is deflected on the connecting frame 634, the plurality of shielding plates 633 shield the part between the tilted bottom end of the movable baffle 62 and the inner circumferential surface of the tower body 1, so that the ether post-carbon four mixture moves from the tilted bottom end of the fixed baffle 61 to the tilted top end of the fixed baffle 61 when passing through the fixed baffle 61, and passes through the fixed baffle 61 from the tilted top end position.

[0046] When the fixed baffle 61 becomes a horizontal state, at this time, the shielding plate 633 reverts to a vertical state with the connecting frame 634, the plurality of shielding plates 633 block one half region between the fixed baffle 61 and the inner circumferential surface of the tower body 1, and the sealing gasket 632 blocks the other half region between the fixed baffle 61 and the inner circumferential surface of the tower body 1, so that the ether post-carbon four mixture flows upward from the coincident region of the fixed baffle 61 and the fan-shaped vacancy of the movable baffle 62.

[0047] As Figure 3 , Figure 5 and Figure 6As shown, the drainage member 64 includes a through hole 642 opened on the upper surface of the movable baffle 62, the through hole 642 is located on the side of the movable baffle 62 inclined downward with the fixed baffle 61, the upper surface of the movable baffle 62 is fixedly connected with an M-shaped support 641 at the position corresponding to the through hole 642, the bottom end of the middle vertical section of the M-shaped support 641 is fixedly connected with a closing plate 643, the two vertical sections of the M-shaped support 641 are elastically arranged, the elastic force of the M-shaped support 641 is adaptively set by the person skilled in the art according to multiple tests, so as to ensure that when the water accumulates to a certain amount, the downward thrust on the closing plate 643 is greater than the elastic force of the M-shaped support 641, so as to open the channel, under normal circumstances, the water will flow downward from the gap between the plurality of shielding plates 633, when the water accumulates to a certain amount at the position of the closing plate 643, the water will push the closing plate 643 away on the movable baffle 62 to flow downward, the diameter of the closing plate 643 is matched with the diameter of the through hole 642 and is in sliding fit, under normal circumstances, the closing plate 643 is embedded in the inside of the through hole 642 and the lower surface of the closing plate 643 is flush with the lower surface of the movable baffle 62.

[0048] In specific use, when the fixed baffle 61 is in an inclined state, the shielding plate 633 blocks the position of the fixed baffle 61 inclined downward, at this time, the water accumulates at the position of the fixed baffle 61 inclined downward, when the water accumulates to a certain amount, the downward thrust on the closing plate 643 is greater than the elastic force of the M-shaped support 641, at this time, the water pushes the closing plate 643 to move downward in the inside of the through hole 642, the closing plate 643 is separated from the through hole 642, and the water flows downward from the position of the through hole 642, while ensuring that the ether after carbon four mixture passes through the top of the inclined position of the fixed baffle 61 as much as possible, the water is prevented from accumulating too much at the position of the fixed baffle 61 inclined downward.

[0049] As shown in Figure 3 and Figure 7 , the knocking member 51 further includes a plurality of circumferentially arrayed clamping grooves 512 uniformly opened on the upper surfaces of the inner and outer rings of the knocking component 511, the clamping grooves 512 are internally mounted with the knocking balls 513 which can slide in the inside of the clamping grooves 512.

[0050] As shown in Figure 3 , Figure 7 and Figure 8As shown, the adjusting member 53 includes a fixed shell 533 fixedly connected at a position corresponding to the through slot of the outer circumferential surface of the tower body 1, the lower surface of the fixed shell 533 is slidingly and penetratingly connected with a limiting rod 532, the connecting piece on the knocking component 511 extends into the corresponding fixed shell 533, a reset spring is arranged between the lower surface of the connecting piece and the inner wall of the bottom end of the fixed shell 533, the reset spring is made of rust-proof and corrosion-resistant material, for example, stainless steel spring and special alloy spring, one end of the limiting rod 532 located in the fixed shell 533 is at the middle position of the reset spring, the sliding connection position between the limiting rod 532 and the fixed shell 533 is sealingly arranged, the bottom ends of the plurality of limiting rods 532 on the same horizontal plane are fixedly connected with a linkage ring 531, the lower surface of the linkage ring 531 on the bottom layer is fixedly connected with the telescopic end of the hydraulic cylinder 52, and the plurality of limiting rods 532 are linked through linkage rods.

[0051] As shown, Figure 3 As shown, the linkage mechanism 7 includes a second pull rod 72 hingedly connected on the circumferential surface of the support rod of the knocking component 511 through a pulling frame and corresponding to one side of the shielding piece 63, and a first pull rod 71 hingedly connected on the upper surface of the movable baffle 62 and corresponding to one side of the shielding piece 63, the setting of the pulling frame can make the pulling force generated by the second pull rod 72 be distributed on a plurality of point positions on the lower surface of the knocking component 511, so as to ensure that the knocking component 511 remains vertically downwardly moving when subjected to the downward pulling force of the second pull rod 72, a second torsional spring (not shown in the figure) is arranged between the second pull rod 72 and the support rod, the second torsional spring is made of rust-proof and corrosion-resistant material, for example, stainless steel spring and special alloy spring, the second pull rod 72 remains in a vertical state in a normal state, the top end of the first pull rod 71 is fixedly connected with an electromagnet 74, the electromagnet 74 is waterproofly sealed, and is connected with an external power supply through a waterproof wire, the magnetic attraction force of the electromagnet 74 is greater than the sum of the elastic forces of the plurality of reset springs, the bottom end of the second pull rod 72 is provided with a magnetic attraction piece, an arc-shaped auxiliary rod 73 is fixedly connected on the upper surface of the movable baffle 62 and corresponding to the position of the first pull rod 71, the first pull rod 71 is slidingly fitted with the arc-shaped auxiliary rod 73, a limiting spring is sleeved on both sides of the arc-shaped auxiliary rod 73 and located above the first pull rod 71, the limiting spring is made of rust-proof and corrosion-resistant material, for example, stainless steel spring and special alloy spring, the first pull rod 71 remains in a vertical state in a normal state.

[0052] In specific use, when the fixed baffle 61 is in a horizontal state, the electromagnet 74 on the pull rod one 71 is powered on, at which time the electromagnet 74 and the magnetic attraction piece are adsorbed together, when the fixed baffle 61 changes from horizontal to inclined, the fixed baffle 61 generates a downward pulling force on the knocking part 511 in the deflection process through the cooperation of the pull rod one 71 and the pull rod two 72 and the electromagnet 74, drives the knocking part 511 to move downward, the connecting piece on the knocking part 511 slides downward in the through slot on the tower body 1, and the reset spring inside the fixed shell 533 is compressed, when the connecting piece moves downward and abuts against the top end of the limiting rod 532, at this time the two electromagnets 74 are powered off, the two electromagnets 74 are separated, at this time the knocking part 511 is no longer subjected to the pulling force, and quickly recovers to the original position under the action of the elastic force of the reset spring itself, (as Figure 9 The knocking ball 513 inside the clamping groove 512 knocks the filler 4, and the filler 4 generates vibration after being knocked, and the blockage on the filler 4 is cleared through vibration.

[0053] According to the use time of the water washing tower, the limiting rod 532 can be extended into the fixed shell 533 to adjust the length of the limiting rod 532, when the limiting rod 532 extends into the fixed shell 533 to a greater length, at this time the downward movement distance of the knocking part 511 is shorter, and the compression deformation amount of the reset spring is smaller, so that the elastic force provided by the knocking part 511 is smaller, and vice versa, the elastic force provided by the knocking part 511 is greater, and the size of the elastic force determines the size of the knocking force of the filler 4 after being knocked by the knocking ball 513.

[0054] It should be noted that the position of the knocking ball 513 inside the clamping groove 512 moves randomly when the knocking part 511 moves upward to the original position each time, so as to randomly knock the lower surface of the filler 4, and the vibration cleaning of the blockage on the filler 4 through knocking is based on the existing normal cleaning of the filler 4, the vibration cleaning of the blockage on the filler 4 can prolong the existing cleaning period of the filler 4, and the filler 4 can maintain high efficiency for a longer time, so that the passing rate of the ether after carbon four mixture of the filler 4 decreases smaller at the end of the two cleaning periods, so as to ensure that the water washing effect of the ether after carbon four mixture is better.
