Description

Technical Field

[0001] The invention relates to the technical field of zeolite adsorbers, in particular to a deacidification device and method for filtering C4 liquefied gas. Background Art

[0002] C4 exists in oilfield gas, wet natural gas and cracked gas. For example, in the petrochemical light oil cracking ethylene production unit, the co-produced C4 hydrocarbons account for about 40% of the ethylene production; the C4 hydrocarbons produced by the catalytic cracking unit of the oil refinery account for about 6% of the unit's processing capacity, and C4 can be obtained after separation. In the production process of C4, C4 liquefied gas is often produced, and the separated C4 liquefied gas mostly contains a large amount of acidic substances. In order to prevent the acidic substances from corroding the equipment and affecting the product quality, zeolite adsorbers (also known as molecular sieve adsorbers) are currently commonly used to deacidify and filter the C4 liquefied gas.

[0003] As in the prior art, a patent with a patent authorization announcement number of CN220071195U discloses an adsorber for a zeolite rotor, comprising a zeolite rotor body and an adsorption cover that passes through left and right, the zeolite rotor body being rotatably connected to the middle position of the adsorption cover, the zeolite rotor body comprising a ring frame and a plurality of zeolite wheel cores fixedly mounted on the ring frame, two diverter plates that are symmetrically arranged on the left and right sides of the zeolite rotor body and are sealed and rotated with the ring frame, a sealing plate is fixedly connected to the side of the diverter plate away from the zeolite rotor body, a cold air bin and a hot air bin are formed between the diverter plate, the sealing plate, the zeolite rotor body and the adsorption cover, the cold air bin and the hot air bin are respectively matched with two adjacent zeolite wheel cores, and this adsorber for a zeolite rotor is convenient for regenerating the local adsorption capacity of the zeolite rotor while the zeolite rotor is performing adsorption work, so that the entire zeolite rotor continues to maintain a certain adsorption capacity.

[0004] Although the zeolite adsorber in the above patent can regenerate the local adsorption capacity of the zeolite rotor while the zeolite rotor is performing adsorption work, so that the entire zeolite rotor continues to maintain a certain adsorption capacity, the zeolite adsorber has certain defects; since the existing zeolite adsorber has a zeolite rotor that rotates continuously in order to continue to perform adsorption work, the desorption time of the zeolite rotor in the regeneration and desorption zone is limited, which results in the zeolite rotor being able to perform partial desorption during use, and in order to maintain the overall adsorption effect of the zeolite adsorber, the rotation speed of the zeolite adsorber cannot be greatly changed. Therefore, the existing zeolite adsorber has a limited regeneration effect on the local adsorption capacity of the zeolite rotor, and it is difficult to improve the regeneration effect of the zeolite adsorber on the local adsorption capacity of the zeolite rotor. Therefore, the current zeolite adsorber needs to be improved. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a deacidification device and method for carbon four liquefied gas filtration to solve the problems raised by the background technology, so that the molecular sieve module can have a longer time for desorption to improve the desorption effect, thereby improving the adsorption effect of the molecular sieve module.

The rotating gear is located inside the annular groove. The rotating gear is meshed with the tooth block. The positioning block is rotatably connected to the rotating gear. The other end of the positioning block is fixedly connected to the inner wall of the adsorber body.

[0010] Further, the transmission assembly includes a second transmission belt, a rotating shaft, a transverse bevel gear, a vertical bevel gear, a connecting rod, a connecting plate, a support rod, a third transmission belt and a pushing gear.

[0016] Step 3: After the rotary frame rotates to a predetermined angle, the motor stops working, and the molecular sieve module in the air duct is aligned with the molecular sieve module on the rotary frame. At the same time, the pushing component releases the accumulated energy to push the molecular sieve module to move, thereby replacing the molecular sieve module in the air duct with the molecular sieve module on the rotary frame.

[0017] Step 4: After the adsorber body continues to work for a period of time, the motor starts working again. The motor drives the rack plate to move in the opposite direction through the conversion component and the transmission component, so that the push component at the other end of the rack plate can store energy;

In this way, the molecular sieve module will have a better effect during adsorption, thereby improving the adsorption effect of the adsorber main body. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] See also Figures 1 to 12 The present invention provides a deacidification device for filtering C4 liquefied gas, comprising an adsorber body 1, a filter 2, a frame 3, an air duct 5, a heater 6 and an inlet and outlet pipe 7 installed in the adsorber body 1, a rotating wheel frame 4 is rotatably connected to the middle position of the frame 3, a motor 21 is fixedly connected to the lower end of one side of the frame 3, the output end of the motor 21 is connected to the rotating wheel frame 4 through a first transmission belt 22, a fixed block 10 is fixedly connected to the inner side of the rotating wheel frame 4, a plurality of molecular sieve modules 8 slidably connected to the fixed block 10 are arranged inside the rotating wheel frame 4, the molecular sieve module 8 is filled with molecular sieve particles, and a slot 9 matching the fixed block 10 is opened on the molecular sieve module 8, a regeneration zone and a cooling zone are respectively arranged inside the air duct 5 from left to right, the inner wall of the regeneration zone of the air duct 5 is fixedly connected to a limit plate 11, the bottom of the limit plate 11 is fixedly connected to a slide rail 12 matching the slot 9, a rack plate 13 is slidably connected to the top of the frame 3, both ends of the rack plate 13 are connected to a pushing assembly, and a transmission assembly and a conversion assembly are arranged on one side of the rack plate 13.

[0036] In the deacidification equipment for filtering C4 liquefied gas of the present invention, when in use, the motor 21 will work regularly under the control of the adsorber body 1, and when the motor 21 is working, it will drive the rotating wheel frame 4 to rotate a certain angle (the angle is the same as the angle of the molecular sieve module 8) through the conversion component and the transmission component. At the same time, the conversion component and the transmission component will also drive the rack plate 13 to move, and the rack plate 13 will drive the pushing component to move. When the pushing component moves, since the molecular sieve module 8 cannot be pushed by the pushing component, one end of the pushing component will be compressed, thereby storing energy. When the rotating wheel frame 4 stops rotating (at this time, the molecular sieve module 8 installed on the rotating wheel frame 4 will be aligned with the molecular sieve module 8 in the regeneration area of ​​the air duct 5). Since the molecular sieve module 8 in the regeneration area of ​​the air duct 5 has been aligned with the molecular sieve module 8 installed on the rotating wheel frame 4, the molecular sieve module 8 in the regeneration area of ​​the air duct 5 is no longer hindered, and the pushing component will release energy to push the molecular sieve module 8 in the regeneration area of ​​the air duct 5 to move toward the rotating wheel frame 4, so that the molecular sieve module 8 in the regeneration area of ​​the air duct 5 can be inserted into the rotating wheel frame 4, and the molecular sieve module 8 originally located in the rotating wheel frame 4 will enter the regeneration area of ​​the air duct 5 (but compared with the molecular sieve module 8 originally located in the air duct 5, it is located on the other side of the rotating wheel frame 4);

[0037] After the adsorber body 1 has worked for a period of time (the working time of the adsorber body 1 is the same as the downtime of the motor 21. Since the motor 21 of the device works intermittently, the downtime of the motor 21 is the same as the time required for the existing molecular sieve adsorber to rotate a certain angle (the angle is the same as the angle of the molecular sieve module 8), and the subsequent working time of the adsorber body 1 is equal to this time), the motor 21 will work again and drive the rack plate 13 to move through the conversion component and the transmission component. Under the action of the conversion component, the rack plate 13 will move in the opposite direction, allowing the pushing component at the other end of the rack plate 13 to store energy until the rotating wheel frame 4 stops rotating, and the pushing component will push it The molecular sieve module 8 that was pushed out before (i.e., the molecular sieve module 8 that was detached from the rotary frame 4 when the rotary frame 4 rotated last time) is pushed back into the rotary frame 4, and the molecular sieve module 8 inside the rotary frame 4 is pushed out; during the operation of the adsorber main body 1, the above actions will be repeated until the adsorber main body 1 stops. Since a molecular sieve module 8 is provided inside the air duct 5, each molecular sieve module 8 that rotates to the regeneration zone of the air duct 5 will have double desorption and regeneration time, thereby improving the regeneration effect of the molecular sieve particles inside the molecular sieve module 8 in the regeneration zone of the air duct 5, and the molecular sieve particles in the molecular sieve module 8 have a better regeneration effect, which also makes the adsorption effect of the adsorber main body 1 better;

[0038] During the operation of the adsorber body 1, the waste gas to be treated will enter the adsorption zone of the adsorber body 1, and the volatile organic compounds or other pollutants in the waste gas will be captured by the zeolite adsorbent in the molecular sieve module 8, so that the molecular sieve module 8 gradually enters a saturated state. During this process, the rotary wheel frame 4 will keep rotating intermittently, so that the molecular sieve module 8 that has entered a saturated state can enter the regeneration zone (i.e., the position of the air duct 5), and the pollutants adsorbed on the zeolite in the molecular sieve module 8 will be desorbed by heating or vacuum operation, so that the zeolite can restore its adsorption capacity. At the same time, the molecular sieve module 8 in a saturated state on the rotary wheel frame 4 will be replaced by a pushing component, so that the molecular sieve module 8 that has been desorbed in the air duct 5 is connected to the rotary wheel frame 4, so that the molecular sieve module 8 in a saturated state has more desorption time, thereby improving the regeneration effect, and the pollutant gas released during the regeneration process will be collected and discharged after being treated by combustion or chemical reaction to meet the emission standards;

[0039] In addition, the structures of the adsorber body 1, the filter 2, the frame 3, the air guide 5, the heater 6 and the air inlet and exhaust pipes 7 in the present invention are similar to the prior art, and the structure of a zeolite rotor adsorber disclosed in the patent authorization announcement number CN220071195U is similar, so no further elaboration is made here.

[0040] As a preferred technical solution of the present invention, the pushing assembly includes an end plate 15, a positioning rod 16, a pushing frame 17 and an elastic member 18. The end plate 15 is installed at the end of the rack plate 13, the positioning rod 16 is slidably connected to the end plate 15, the pushing frame 17 is fixedly connected to one end of the positioning rod 16 close to the frame 3, the pushing frame 17 matches the molecular sieve module 8, and the pushing frame 17 is slidably connected to the air duct 5, the elastic member 18 is sleeved on the outside of the positioning rod 16, one end of the elastic member 18 is fixedly connected to the positioning rod 16, and the other end of the elastic member 18 is fixedly connected to the pushing frame 17.

[0041] Specifically, when the rotary frame 4 rotates and the rack plate 13 moves, the rack plate 13 will drive the end plate 15 to move together. Since the molecular sieve module 8 located inside the air duct 5 has not yet been aligned with the molecular sieve module 8 installed on the rotary frame 4 at this time, the molecular sieve module 8 in the air duct 5 cannot be inserted into the rotary frame 4, so the pushing frame 17 cannot move. At this time, when the end plate 15 moves toward the direction of the rotary frame 4, it will squeeze the elastic member 18 and store energy by squeezing the elastic member 18. When the rotary frame 4 stops rotating (at this time, the molecular sieve module 8 installed on the rotary frame 4 will be aligned with the molecular sieve module 8 in the regeneration area of ​​the air duct 5), the pushing frame 17 can push the molecular sieve module 8 to move, and the elastic member 18 will release the accumulated elastic potential energy to push the molecular sieve module 8 in the air duct 5 into the rotary frame 4, thereby completing the replacement of the molecular sieve module 8.

[0042] As a preferred technical solution of the present invention, both ends of the rack plate 13 are fixedly connected with threaded rods 14, the end plate 15 is slidably connected to the threaded rod 14, and the side of the end plate 15 away from the frame 3 is rotatably connected to a limiting ring 19, the limiting ring 19 is sleeved on the outside of the threaded rod 14, and one side of the limiting ring 19 is fixedly connected with a nut 20 fixed to the threaded rod 14.

[0043] Specifically, after working for a long time, the elastic coefficient of the elastic member 18 may change sometimes, resulting in the elastic member 18 being unable to push the molecular sieve module 8 to the specified position when pushing the molecular sieve module 8 through the pushing frame 17 (that is, the molecular sieve module 8 in the air duct 5 cannot be completely pushed into the rotating wheel frame 4). At this time, the nut 20 can be rotated to move the end plate 15 toward the direction of the rotating wheel frame 4, shortening the distance between the end plate 15 and the rotating wheel frame 4, so that the molecular sieve module 8 in the air duct 5 can be more easily pushed into the rotating wheel frame 4.

[0044] As a preferred technical solution of the present invention, the conversion component includes a turntable 23, a rotating gear 25 and a positioning block 26. The turntable 23 is fixedly connected to the output end of the motor 21. An annular groove 24 is opened on the turntable 23. A half-circle tooth block is fixedly connected to the inner ring of the annular groove 24, and a half-circle tooth block is fixedly connected to the outer ring of the annular groove 24. The tooth blocks on the inner and outer rings of the annular groove 24 are staggered. The rotating gear 25 is located inside the annular groove 24, the rotating gear 25 is meshed with the tooth block, the positioning block 26 is rotatably connected to the rotating gear 25, and the other end of the positioning block 26 is fixedly connected to the inner wall of the adsorber body 1.

[0045] Specifically, since staggered tooth blocks are arranged on the inner and outer rings of the annular groove 24, when the rotating gear 25 contacts the tooth blocks at different positions, it can rotate in different directions, thereby converting the unidirectional circular motion of the motor 21 into rotary motion, facilitating the reciprocating motion of the rack plate 13.

[0046] As a preferred technical solution of the present invention, the transmission assembly includes a second transmission belt 27, a rotating shaft 28, a transverse bevel gear 29, a vertical bevel gear 30, a connecting rod 31, a connecting plate 32, a support rod 33, a third transmission belt 34 and a pushing gear 35. The rotating shaft 28 is rotatably connected to the frame 3, the transverse bevel gear 29 is fixedly connected to the rotating shaft 28, the second transmission belt 27 is sleeved on the outer side of the rotating shaft 28 and the rotating gear 25, the connecting plate 32 is fixedly connected to the frame 3, the connecting rod 31 and the support rod 33 are both rotatably connected to the connecting plate 32, the vertical bevel gear 30 is fixedly connected to the bottom of the connecting rod 31, the vertical bevel gear 30 is meshed with the transverse bevel gear 29, the third transmission belt 34 is sleeved on the outer side of the connecting rod 31 and the support rod 33, the pushing gear 35 is fixedly connected to the top of the support rod 33, and the pushing gear 35 is meshed with the rack plate 13.

[0047] Specifically, when the rotary gear 25 rotates, the second transmission belt 27 drives the rotating shaft 28 to rotate, and the rotating shaft 28 drives the transverse bevel gear 29 to rotate, so that the vertical bevel gear 30 meshing with the transverse bevel gear 29 can be rotated. When the vertical bevel gear 30 rotates, the connecting rod 31 and the third transmission belt 34 drive the support rod 33 to rotate, and the support rod 33 drives the push gear 35 to rotate, so that the rack plate 13 moves (it is worth noting that although the description in the appendix Figure 5 The distance between the middle push gear 35 and the support rod 33 is relatively close, and it seems that there is no need to design the third transmission belt 34 and the support rod 33, but in reality there is a certain distance between them, so this structure does not belong to an unnecessary complex structure).

[0048] As a preferred technical solution of the present invention, both ends of the fixing block 10 and the slide rail 12 are provided with chamfers. After the chamfers are provided, the fixing block 10 and the slide rail 12 are more easily inserted into the slot 9 on the molecular sieve module 8.

[0049] As a preferred technical solution of the present invention, guiding slopes are provided at the edge positions on both sides of the molecular sieve module 8 .

[0050] Specifically, due to the existence of the guiding slope, even if the end of the molecular sieve module 8 fails to remain flush with the side of the rotating wheel frame 4 and there is a certain error, when the rotating wheel frame 4 rotates, the air guide duct 5 will push the molecular sieve module 8 through the guiding slope, so that the end of the molecular sieve module 8 remains flush with the side of the rotating wheel frame 4, and will not affect the normal rotation of the rotating wheel frame 4.

[0051] The present invention also provides a deacidification method based on the above-mentioned deacidification equipment for carbon four liquefied gas filtration: after the adsorber body 1 works for a period of time, the motor 21 is started, and the motor 21 drives the rotary wheel frame 4 to rotate a predetermined angle. When the motor 21 is working, the rack plate 13 is driven to move through the conversion component and the transmission component, so that the push component can store energy. After the rotary wheel frame 4 rotates to a predetermined angle, the motor 21 stops working. At this time, the molecular sieve module 8 located in the air duct 5 will be aligned with the molecular sieve module 8 on the rotary wheel frame 4, and the push component will release the accumulated energy to push the molecular sieve module 8 to move, thereby replacing the molecular sieve module 8 in the air duct 5 with the molecular sieve module 8 on the rotary wheel frame 4. After the adsorber body 1 continues to work for a period of time, the motor 21 works again, and the motor 21 drives the rack plate 13 to move in the opposite direction through the conversion component and the transmission component, so that the push component at the other end of the rack plate 13 can store energy. After the rotary wheel frame 4 rotates a predetermined angle, the motor 21 will stop working again, and then repeat the above operation (this operation refers to replacing the molecular sieve module 8 on the rotary wheel frame 4 with the molecular sieve module 8 located in the air duct 5). The above operation will be repeated during the operation of the adsorber body 1 until the adsorber body 1 stops.

[0052] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
