Description

Technical Field

[0001] The invention belongs to the technical field of waste gas treatment, in particular to a molecular sieve roasting tail gas treatment device. Background Art

[0002] Molecular sieve is a material with a uniform microporous structure that can selectively adsorb or separate components in a mixture based on molecular size and polarity. The molecular sieve needs to be calcined during preparation. High-temperature heat treatment is used to remove the template, activate the pores, stabilize the structure, and regulate performance. High-temperature exhaust gas is inevitably generated during the molecular sieve calcination process. In order to protect the environment, the exhaust gas needs to be purified.

[0003] When treating the waste gas generated by the roasting of molecular sieves, an absorption tower is usually used for absorption treatment. There are filler layers, absorption layers, etc. inside the absorption tower. When the waste gas passes through the absorption layer of the absorption tower, the dust in the waste gas will be filtered by the absorption layer. In addition, the absorption layer will also absorb specific components in the waste gas. After a period of use, the absorption capacity of the absorption layer reaches its limit, and the staff needs to clean the absorption layer. Specifically, when cleaning the absorption layer, the staff needs to flush it with a high-pressure water gun. For stubborn dirt, it needs to be disassembled and cleaned. The entire cleaning process requires the absorption tower to be deactivated, that is, it can no longer treat the waste gas, affecting the waste gas treatment efficiency.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 5As shown, a molecular sieve roasting tail gas treatment device according to an embodiment of the present invention includes a tower body 1, the tower body 1 includes a lower component 101 and an upper component 102, a receiving frame 14 is slidably connected between the lower component 101 and the upper component 102, an absorption layer 15 is fixedly connected to the interior of the receiving frame 14, the side of the lower component 101 is connected and fixedly connected to the air inlet pipe 11, the top of the upper component 102 is connected and fixedly connected to the air outlet pipe 12, a lifting hydraulic cylinder 13 is fixedly connected to the side of the lower component 101, and a linkage frame is fixedly connected between the output end of the lifting hydraulic cylinder 13 and the upper component 102; A pair of rails 2 are provided on both sides of the tower body 1, and a support frame 3 is fixedly connected to the bottom of the rail 2. A slider 22 is slidably connected to the inside of the rail 2, and a threaded hole is provided on the side of the slider 22. A screw 23 is engaged and inserted into the inside of the threaded hole. A motor is provided at the end of the screw 23, and the motor is fixed to the end of the rail 2. The output end of the motor is connected to the end of the screw 23. A support block 21 is fixed to the top of the slider 22, and a connecting frame 24 is fixed between the pair of support blocks 21. A reserved receiving frame 14 is fixed to the side of the support block 21, and the receiving frame 14 between the lower component 101 and the upper component 102 is fixed to the connecting frame 24; At present, the absorption tower used for the treatment of molecular sieve roasting tail gas needs to be cleaned regularly. Specifically, during cleaning, the staff needs to flush it with a high-pressure water gun. For stubborn dirt, it needs to be disassembled and cleaned. The entire cleaning process requires the absorption tower to be shut down, that is, it cannot continue to treat the exhaust gas, which affects the treatment efficiency of the exhaust gas. In order to solve the above problems, the embodiment of the present invention provides a plurality of receiving frames 14, and the absorption layer 15 is installed inside the receiving frame 14. When the absorption tower is in normal use, the exhaust gas enters the tower body 1 through the air inlet pipe 11, and then the dust in the exhaust gas is separated from the absorption layer 15. Other impurities are absorbed and filtered, and then the exhaust gas enters another tower body 1 through the outlet pipe 12 for subsequent purification treatment. When the absorption layer 15 needs to be cleaned, the motor is started, and the motor drives the screw 23 to rotate. The screw 23 is engaged with the threaded hole on the slider 22. Therefore, when the screw 23 rotates, the slider 22 drives the support block 21 to move along the track 2. When the support block 21 moves, it drives the connecting frame 24 to move synchronously. When the connecting frame 24 moves, the receiving frame 14 between the upper part 102 and the lower part 101 moves synchronously. At the same time, the lifting hydraulic cylinder 13 is started, and the lifting hydraulic cylinder 1 The output end drives the linkage frame to move upward, and the linkage frame drives the upper part 102 to move upward. The squeezing of the bottom end of the upper part 102 on the receiving frame 14 is released, so that the receiving frame 14 between the upper part 102 and the lower part 101 moves smoothly. As the receiving frame 14 between the upper part 102 and the lower part 101 moves, the receiving frame 14 inside the isolation frame 5 moves synchronously. When the support block 21 stops moving, the receiving frame 14 originally located between the upper part 102 and the lower part 101 is driven into the isolation frame 5, and the receiving frame 14 originally located in the isolation frame 5 moves to the upper The upper component 102 is placed between the upper component 102 and the lower component 101, and then the upper component 102 is controlled to reset. At this time, the absorption layer 15 inside the receiving frame 14 between the upper component 102 and the lower component 101 is in a clean state, and the exhaust gas treatment process can continue. The staff only needs to clean the absorption layer 15 in the original receiving frame 14. The cleaning process does not require the absorption tower to be stopped, and the exhaust gas can continue to be treated, avoiding affecting the exhaust gas treatment efficiency. In addition, receiving frames 14 are reserved in the isolation frames 5 on both sides of the absorption tower. There is a clean absorption layer 15 in the receiving frame 14, which can be moved and replaced when replacing the absorption layer 15; It should be pointed out that there may be other treatment layers such as a packing layer in the absorption tower. In the embodiment of the present invention, the absorption tower is used to clean the absorption layer 15. If other treatment layers are to be cleaned, the same structure as that of the replacement absorption layer 15 may be set to replace the other treatment layers.

[0023] like Figures 10 to 14As shown, a pair of isolation frames 5 are provided on both sides of the tower body 1. The receiving frame 14 connected to the support block 21 is initially located inside the isolation frame 5. The absorption layer 15 inside the receiving frame 14 is isolated by the isolation frame 5. An annular ring 51 is provided on the surface of the isolation frame 5 and on the upper and lower sides of the receiving frame 14. The end of the annular ring 51 away from the isolation frame 5 is slidably connected to a sealing plate 52. A nozzle 53 is inserted on the side of the sealing plate 52. The side of the nozzle 53 is connected to a water guide component. When the absorption layer 15 to be cleaned is driven into the isolation frame 5, the receiving frame 14 will be located between the pair of nozzles 53. When cleaning the absorption layer 15, the water-guiding component located above the isolation frame 5 injects cleaning liquid into the nozzle 53, and the upper nozzle 53 will spray liquid water, and the isolation frame 5 between the pair of nozzles 53 is provided with a circular hole; the cleaning liquid sprayed by the nozzle 53 acts on the absorption layer 15 inside the receiving frame 14 through the circular hole, and the water-guiding component located below the absorption layer 15 draws away the cleaning liquid that penetrates from the top of the absorption layer 15 to the bottom. In addition, the nozzle 53 below the absorption layer 15 can also spray cleaning liquid to rinse the bottom surface of the absorption layer 15, and then the cleaning liquid is drawn away to realize automatic cleaning of the absorption layer 15 and improve the automation effect.

[0024] The water guide assembly includes a pad 54, which is slidably connected to the side of the nozzle 53. A notch is opened on the surface of the pad 54 and is connected to the nozzle 53. A water pipe 56 connected to the notch is fixedly connected to the side of the pad 54. A connecting piece 55 is fixedly connected between the side of the water pipe 56 and the sealing plate 52; the water pipe 56 is externally connected to a water pump. When the water pump is started in use, the water pump draws the external cleaning liquid into the notch through the water pipe 56, and then into the inside of the nozzle 53, and finally sprays it out from the nozzle 53 to rinse the absorption layer 15; in addition, a pressure relief valve 57 is fixedly connected to the side of the water pipe 56. The pressure relief valve 57 is fixedly connected to the side of the water pipe 56. The output end of 7 is connected and fixedly connected with a drain pipe 58, and the end of the drain pipe 58 away from the pressure relief valve 57 is connected and fixedly connected with a water tank 59, and the inner bottom wall of the water tank 59 is fixedly connected with an inclined plate 591. A water baffle 592 is provided at the connection between the water tank 59 and the water guide pipe 56, and an elastic sheet is fixedly connected between the top of the water baffle 592 and the inner top wall of the water tank 59. There is a gap between the bottom end of the water baffle 592 and the end of the inclined plate 591; when the nozzle 53 sprays the cleaning liquid, when the cleaning liquid has too great an impact force on the absorption layer 15, it may cause damage to the absorption layer 15, so a pressure relief valve 57 is provided, and the pressure relief valve 57 is connected to the water guide pipe 56. The water pressure inside the water pipe 56 is proportional to the water pressure inside the nozzle 53. Therefore, controlling the water pressure inside the water pipe 56 can control the water pressure inside the nozzle 53, thereby preventing the nozzle 53 from spraying out cleaning liquid with excessive impact force to damage the absorption layer 15. When the water pressure inside the water pipe 56 reaches a preset value, the pressure relief valve 57 will automatically open to receive the cleaning liquid into the drain pipe 58, and then the cleaning liquid will enter the water tank 59. The size of the water tank 59 can be adjusted as needed. The cleaning liquid entering the water tank 59 is received by the inclined plate 591, and there is water pressure on the side of the water baffle 592 facing the water pipe 56, so the bottom of the water baffle 592 will move upward. The inclined plate 591 is deflected in the direction to block the gap between the inclined plate 591 and the bottom end of the water baffle 592. The cleaning liquid on the inclined plate 591 is blocked by the water baffle 592. When cleaning is completed, the water pressure inside the water pipe 56 disappears, and the side of the water baffle 592 facing the water pipe 56 loses the water pressure effect, and the bottom end is deflected away from the inclined plate 591, thereby opening the gap between the bottom end of the water baffle 592 and the inclined plate 591. The cleaning liquid received on the inclined plate 591 will flow into the water pipe 56 through the gap, and finally enter the nozzle 53, and flow downward through the nozzle 53 to clean the absorption layer 15 below, thereby avoiding waste of the discharged cleaning liquid.

[0025] A crossbar 511 is fixedly connected to the inside of the annular ring 51, and a flexible cleaning head 512 is fixedly connected to the bottom end of the crossbar 511. The end of the flexible cleaning head 512 contacts the absorption layer 15 inside the receiving frame 14; The cross bar 511 is fixedly connected to a rotating shaft 513 at the midline of the side facing the nozzle 53, and the side of the rotating shaft 513 is fixedly connected to a plurality of water-blocking inclined plates 514 in an annular shape; the bottom end of the annular ring 51 is sleeved with a sealing ring 510, and the sealing ring 510 is fixedly connected to the surface of the isolation frame 5; when the nozzle 53 sprays cleaning liquid, the cleaning liquid will impact the water-blocking inclined plates 514, and the water-blocking inclined plates 514 will generate a torsional force when impacted, and the water-blocking inclined plates 514 will transmit the torsional force to the rotating shaft 513, and the rotating shaft 513 will transmit the torsional force to the cross bar 51, and the cross bar 511 drives the annular ring 51 under the action of the torsional force 1 rotates, and the annular ring 51 is slidably connected with the sealing plate 52 at the top when it rotates, and the sealing ring 510 will limit the rotation position of the annular ring 51 to ensure that the annular ring 51 rotates stably. The cross bar 51 inside the annular ring 51 drives the flexible cleaning head 512 to rotate synchronously. The end of the flexible cleaning head 512 is a flexible brush and contacts the absorption layer 15. As the flexible cleaning head 512 rotates, the flexible brush on the flexible cleaning head 512 will scrape the surface of the absorption layer 15, and the dust and other dirt on the absorption layer 15 will be quickly cleaned with the flushing of the cleaning liquid, thereby further improving the cleaning efficiency of the absorption layer 15.

[0026] like Figures 10 and 11 As shown, the top of the isolation frame 5 is fixedly connected with a control hydraulic cylinder 541, and the output end of the control hydraulic cylinder 541 is fixedly connected to the pad 54; when there is stubborn dirt on the absorption layer 15, the lower hydraulic cylinder 541 is controlled to start, and the output end of the control hydraulic cylinder 541 drives the pad 54 to move. When the pad 54 moves, the gap is staggered with the water pipe 56, and the other positions of the pad 54 block the water pipe 56; then the cleaning liquid is sprayed to the position of the absorption layer 15, and the cleaning liquid is intercepted by the pad 54 and will not be lost. When the cleaning liquid immerses the absorption layer 15, the pad 54 above the absorption layer 15 is controlled to block the upper water pipe 56, so that the absorption layer 15 is isolated and immersed in the cleaning liquid, so that the stubborn dirt on the absorption layer 15 is fully soaked, which is convenient for subsequent cleaning. It should be pointed out that the cleaning liquid used to soak the absorption layer 15 can be adjusted as needed.

[0027] like Figure 2 As shown, a first one-way valve 1021 is fixedly connected to the side of the upper component 102, and a second one-way valve 1011 is fixedly connected to the side of the lower component 101. The first one-way valve 1021 and the second one-way valve 1011 are both externally connected to an air pump; when the absorption layer 15 between the upper component 102 and the lower component 101 is replaced, the air pumps externally connected to the first one-way valve 1021 and the second one-way valve 1011 are both started, and the first one-way valve 1021 and the second one-way valve 1011 will spray air in an inclined direction toward the middle, thereby preventing the outside air from carrying dust and other impurities into the upper component 102 and the lower component 101, causing pollution to the tower body 1.

[0028] like Figure 7 As shown, a sealing frame 25 is fixedly connected between a pair of support blocks 21, and the sealing frame 25 seals the screw 23 between the pair of support blocks 21 in the track 2, and the end of the slider 22 away from the sealing frame 25 is fixedly connected to a telescopic cylinder structure 26, which is composed of a plurality of cylinders plugged together, and the screw 23 passes through the telescopic cylinder structure 26; the cylinder of the telescopic cylinder structure 26 away from the slider 22 is fixed to the track 2; when the slider 22 moves inside the track 2, the slider 22 will carry the sealing frame 25 to move synchronously through the support block 21, and the sealing frame 25 will seal the screw 23 between the pair of support blocks 21. In addition, when the slider 22 moves, the slider 22 will drive the cylinder of the telescopic cylinder structure 26 to expand and contract, so that the telescopic cylinder structure 26 continuously isolates the screws 23 on both sides of a pair of sliders 22, effectively preventing the lubricating oil on the screw 23 from being dried out, and ensuring smooth engagement of the screw 23 with the threaded hole on the slider 22.

[0029] like Figures 5 to 9 As shown, a rectangular groove 211 is formed at the top of the support block 21, and a pair of push rods 212 are fixedly connected to the inner bottom wall of the rectangular groove 211. A through hole that penetrates into the interior of the threaded hole is formed on the inner bottom wall of the rectangular groove 211 and is located between the pair of push rods 212. A pair of first elastic sheets 213 are fixedly connected to the notch of the rectangular groove 211, and the opposite sides of the pair of first elastic sheets 213 are fixedly connected to the notch of the rectangular groove 211; A pair of positioning frames 41 are fixedly connected to the side of the slide rail 2, and an oil barrel 4 is fixedly connected to the top of the positioning frame 41. The bottom end of the oil barrel 4 is connected and fixed with an oil leakage pipe 42. The oil leakage pipe 42 is made of elastic plastic, and a pair of second elastic sheets 43 are fixed to the bottom end of the oil leakage pipe 42; when the slider 22 drives the support block 21 to move, the top end of the support block 21 will block the oil leakage pipe 42, and the oil leakage pipe 42 will bend. As the support block 21 moves further, the bottom end of the oil leakage pipe 42 is transferred to the top end of the support block 21 and generates relative sliding, and then when it moves above the rectangular groove 211, the pair of first elastic sheets 213 are pushed open, and then inserted into the inside of the rectangular groove 211, and the oil leakage pipe 42 is opened. When 42 enters the rectangular groove 211, the bottom end of the oil leakage pipe 42 is inserted by the push rod 212, and the top of the push rod 212 pushes open the second elastic piece 43 at the bottom end of the oil leakage pipe 42, so that the lubricating oil inside the oil barrel 4 is discharged into the rectangular groove 211 through the oil leakage pipe 42, and then enters the threaded hole through the through hole to achieve lubrication of the threaded hole. After that, as the slider 22 moves further, the oil leakage pipe 42 will be separated from the rectangular groove 211, a pair of first elastic pieces 213 will block the rectangular groove 211, and a pair of second elastic pieces 43 will block the bottom end of the oil leakage pipe 42, thereby achieving automatic oiling of the threaded hole, and then automatically lubricating the screw 23, further improving the automation effect of the present invention.

[0030] A float rod 44 is inserted through the top of the oil barrel 4, and a pressing plate 45 is fixed to the top of the float rod 44. An early warning device 46 is provided below the pressing plate 45 and at the top of the positioning frame 41; as the lubricating oil inside the oil barrel 4 is discharged, the float rod 44 drops as the oil level inside the oil barrel 4 drops. When the oil is emptied, the float rod 44 drives the pressing plate 45 to squeeze the start button of the early warning device 46, and the early warning device 46 sends an early warning signal to an external computer, so as to prompt the staff to replenish the lubricating oil to the oil barrel 4 and prevent the lubricating oil from being unable to be added in time after it is emptied, resulting in the screw 23 not being lubricated in time.
