Description

Technical Field

[0001] The present invention relates to the technical field of chemical equipment, and particularly to an efficient regeneration air purification and energy-saving device for a propane-isobutane mixed dehydrogenation unit. Background Art

[0002] The mixed dehydrogenation of propane and isobutane is a strongly endothermic chemical reaction process, whose main purpose is to remove hydrogen atoms from propane and isobutane to generate corresponding olefins, namely propylene and isobutene. The mixed raw material of propane and isobutane sent from the upstream unit usually contains a small amount of impurities, such as sulfides, moisture, carbon monoxide, carbon dioxide, etc. These impurities may affect the activity and service life of the catalyst, so purification treatment is required. The purified raw material needs to be preheated to increase the temperature of the raw material and provide the energy required for the subsequent dehydrogenation reaction.

[0003] When performing dehydrogenation, a moving bed reactor is needed. The catalyst can move inside the reactor. The deactivated catalyst is removed from the bottom of the reactor for regeneration, and the regenerated catalyst is re-added to the reactor from the top to achieve continuous regeneration of the catalyst and ensure continuous operation of the unit. The raw material gas flows through the catalyst bed for reaction. Before sending the deactivated catalyst into the regenerator, the regenerator usually needs to be preheated to reach a certain temperature range. Usually, a mixture of purified air or oxygen and steam is introduced into the regenerator as the regeneration gas. The steam has two main functions: one is to adjust the oxygen content of the regeneration gas to avoid too violent a regeneration process due to too high an oxygen concentration, which may cause sintering of the catalyst; the other is to participate in the combustion reaction of coke and provide the water vapor required for the water-gas reaction, which helps to remove the coke. When the coke is basically burned out and the catalyst regeneration is completed, the regenerated catalyst needs to be cooled.

[0004] In the prior art, when regenerating the catalyst used in the propane-isobutane mixed dehydrogenation unit, the catalyst is directly placed inside the regenerator, and the catalysts will stack. After the mixed gas is introduced into the regenerator, the coke on the catalyst cannot be efficiently removed, which affects the regeneration efficiency of the catalyst, and also increases energy consumption and is not energy-saving and environment-friendly. At the same time, currently, a filter plate is mostly used to filter particulate impurities in the introduced mixed gas to achieve the purification function. However, after the filter plate is used for a period of time, it needs to be manually cleaned by the staff, which increases the labor intensity of the staff. Therefore, an efficient regeneration air purification and energy-saving device for a propane-isobutane mixed dehydrogenation unit needs to be designed to solve the above problems.

[0005] The information disclosed in this background art section is only intended to enhance the overall understanding of the present invention and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.

[0050] In the description of the present invention, it should be noted that, unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0051] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0052] First embodiment:

[0053] See Figure 1 , Figure 6 ,Figure 7 , Figure 8 and Figure 9 , in the first embodiment of the present invention, the high-efficiency regeneration air purification and energy-saving device of the propane-isobutane mixed dehydrogenation device includes:

[0054] Regenerator 1, on which a main mixing mechanism 2, an auxiliary mixing mechanism 3, an air outlet cleaning mechanism 4 and a driving mechanism 5 are provided;

[0055] The main mixing mechanism 2 includes a round box 201, a top rod 202, a chassis 203, a round cavity 204, a sliding hole 205, an air flow hole 206, an air flow hole 207, an air jet hole 208, a sliding rod 209 and an air flow guiding through hole 210;

[0056] The round box 201 is fixedly installed inside the regenerator 1. It should be noted that the round box 201 is used to hold the catalyst for the propane-isobutane mixed dehydrogenation device. By introducing the mixed gas, the coke on the catalyst is removed inside the regenerator 1, and the catalyst is regenerated;

[0057] The top rod 202 is vertically slidably installed on the round box 201. The top of the chassis 203 is fixedly connected to the top rod 202. The round cavity 204 is opened on the round box 201. The sliding hole 205 is opened at the top of the round box 201. Both the air flow hole 206 and the air flow hole 207 are opened on the round box 204. The air flow hole 206 is connected to the round cavity 204 and the sliding hole 205. The air flow hole 207 is connected to the sliding hole 205. The air jet hole 208 is opened on the inner wall of the top of the round cavity 204. It should be noted that the inner diameter of the air jet hole 208 is smaller than the particle diameter of the catalyst, and the catalyst will not enter the air jet hole 208;

[0058] The sliding rod 209 is slidably and sealingly installed in the sliding hole 205. The air flow guiding through hole 210 is opened on the sliding rod 209;

[0059] Through the above-mentioned main mixing mechanism 2, under the driving action of the driving mechanism 5, the vertical pipe 401 can move vertically back and forth, and then the chassis 203 can be driven to move vertically back and forth. The chassis 203 can drive a plurality of top rods 202 to move vertically back and forth. The top rod 202 can repeatedly push the catalyst in the round box 201, so that the catalyst is in full contact with the mixed gas;

[0060] The auxiliary hybrid mechanism 3 includes a collar 301, an inflation pipe 302, a check valve 1 303, an airbag 304, and an exhaust pipe 305. The collar 301 is fixedly sleeved outside the regenerator 1, the airbag 304 is fixedly sleeved outside the collar 301, the inflation pipe 302 is fixedly installed on the regenerator 1, the collar 301, and the airbag 304. The check valve 1 303 is installed on the inflation pipe 302. A piston is fixedly arranged at the top of the slide bar 209. The piston is in sliding and sealing contact with the inflation pipe 302. A check valve 2 is fixedly arranged on the piston. The exhaust pipe 305 is fixedly installed on the airbag 304 and the round box 201. The exhaust pipe 305 is communicated with the air flow hole 2 207.

[0061] Through the above-mentioned auxiliary hybrid mechanism 3, during the vertical reciprocating movement of the chassis 203, the airbag 304 can be continuously inflated, so that the airbag 304 is always inflated. After the airbag 304 expands to a certain extent, the vertical pipe 401 can be moved upward by the driving mechanism 5, so that the air flow guiding hole 210 is communicated with the air flow hole 2 207 and the air flow hole 1 206. At this time, the air in the airbag 304 will enter the air flow hole 2 207 through the exhaust pipe 305, and then enter the round cavity 204 through the air flow guiding hole 210 and the air flow hole 1 206, and then be ejected through the air jet holes 208 on the round cavity 204. In this way, the catalyst can be quickly blown, so that the mixed gas is in full contact with the catalyst.

[0062] The air outlet cleaning mechanism 4 includes a vertical pipe 401. The vertical pipe 401 is vertically and slidably installed at the central position of the round box 201. The chassis 203 is fixedly sleeved outside the vertical pipe 401.

[0063] In order to ensure the sealing between the top push rod 202 and the round box 201, in this solution, a plurality of top push holes are opened at the bottom of the round box 201, and sealing washers 1 are embedded in the top push holes. The top push rod 202 is in sliding and sealing contact with the sealing washers 1.

[0064] In order to ensure the sealing between the slide bar 209 and the slide hole 205 and prevent the air in the airbag 304 from leaking through the connection, in this solution, a sealing washer 2 is embedded in the slide hole 205. The slide bar 209 is in sliding and sealing contact with the sealing washer 2.

[0065] In this embodiment

[0066] When the catalyst needs to be regenerated, the catalyst is evenly placed into the round box 201. Under the driving action of the driving mechanism 5, the vertical pipe 401 can move vertically in a reciprocating manner, and then the chassis 203 can be driven to move vertically in a reciprocating manner. The chassis 203 can drive a plurality of ejecting rods 202 to move vertically in a reciprocating manner. The ejecting rods 202 can repeatedly eject the catalyst in the round box 201, so that the catalyst is in full contact with the mixed gas. When the chassis 203 moves upward, the chassis 203 drives the sliding rod 209 to move upward, and the sliding rod 209 drives the piston to move upward. The piston can introduce the air on the right side of the check valve 303 in the air charging pipe 302 to the left side of the check valve 303, so that the airbag 304 can be inflated. When the chassis 203 moves downward, the sliding rod 209 moves downward, and the piston moves downward synchronously. The check valve 2 on the piston can allow the outside air to enter the air charging pipe 302. In this way, during the vertical reciprocating movement of the chassis 203, the airbag 304 can be continuously inflated, so that the airbag 304 is always inflated. After the airbag 304 is inflated to a certain extent, the driving mechanism 5 can be used to move the vertical pipe 401 upward. When the vertical pipe 401 moves upward, the sliding rod 209 can be driven to move upward, and the sliding rod 209 drives the air flow guide hole 210 to move upward, so that the air flow guide hole 210 is communicated with the air flow hole 207 and the air flow hole 206. At this time, the air in the airbag 304 will enter the air flow hole 207 through the exhaust pipe 305, and then enter the circular cavity 204 through the air flow guide hole 210 and the air flow hole 206, and then be ejected from the air injection hole 208 on the circular cavity 204. In this way, the catalyst can be quickly blown, so that the mixed gas is in full contact with the catalyst, the coke on the catalyst is removed, the catalyst is regenerated, the regeneration efficiency is improved, and thus it is relatively energy-saving and environmentally friendly.

[0067] Compared with the related art, the high-efficiency regeneration air purification and energy-saving device of the propane-isobutane mixed dehydrogenation device provided by the present invention has the following beneficial effects:

[0068] In the present invention, the vertical pipe 401 can move vertically in a reciprocating manner or be switched. After being switched, it can move upward a certain distance. During the vertical reciprocating movement of the vertical pipe 401, the airbag 304 can be continuously inflated, so that the airbag 304 is always inflated. And during this process, the ejecting rods 202 can repeatedly eject the catalyst in the round box 201, so that the catalyst is in full contact with the mixed gas. After the airbag 304 reaches a certain state, the movement mode of the vertical pipe 401 is switched, so that the vertical pipe 401 can move upward a certain distance, so that the air flow guide hole 210 is communicated with the air flow hole 207 and the air flow hole 206. At this time, the air in the airbag 304 is ejected from the air injection hole 208. In this way, the catalyst can be quickly blown, so that the mixed gas is in full contact with the catalyst, the coke on the catalyst is removed, the catalyst is regenerated, the regeneration efficiency is improved, and thus it is relatively energy-saving and environmentally friendly.

[0069] Second Embodiment

[0070] Based on the high-efficiency regeneration air purification and energy-saving device for the propane-isobutane mixed dehydrogenation unit provided in the first embodiment of the present application, another high-efficiency regeneration air purification and energy-saving device for the propane-isobutane mixed dehydrogenation unit is proposed in the second embodiment of the present application. The second embodiment is merely a preferred mode of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0071] The following further describes the second embodiment of the present invention in conjunction with the drawings and embodiments.

[0072] See Figure 4 、 Figure 5 、 Figure 10 、 Figure 11 、 Figure 12 and Figure 13 , the gas outlet cleaning mechanism 4 further includes a sleeve 402, a vertical rod 403, a rotating pipe 404, a fixed pipe 405, an L-shaped rod 407, a knocking head 408, a filter plate 409, an air outlet pipe 410, a connecting gear 411, a frame body 412, a toothed plate 413, a rigid pipe 414, a solenoid valve 1 415, a solenoid valve 2 416, and a mixed gas introduction hose 417. The bottom of the sleeve 402 is fixedly connected to the vertical pipe 401. The vertical rod 403 is fixedly installed at the top of the sleeve 402. A threaded groove is provided at the top of the vertical rod 403. The rotating pipe 404 is rotatably installed on the sleeve 402. The fixed pipe 405 is fixedly connected to the sleeve 402. The end of the rotating pipe 404 passes through the fixed pipe 405. A plurality of air outlet holes 406 are provided on the outer side of the rotating pipe 404. The L-shaped rod 407 is fixedly installed on the rotating pipe 404. The knocking head 408 is fixedly connected to the L-shaped rod 407. The filter plate 409 is fixedly installed inside the sleeve 402. The air outlet pipe 410 is fixedly installed on the fixed pipe 405. The connecting gear 411 is fixedly sleeved on the outer side of the rotating pipe 404. The frame body 412 is fixedly installed inside the regenerator 1. The toothed plate 413 is fixedly installed on the frame body 412. The toothed plate 413 meshes with the connecting gear 411. The rigid pipe 414 is fixedly connected to the vertical pipe 401. The solenoid valve 1 415 is installed on the vertical pipe 401. The solenoid valve 2 416 is installed on the rigid pipe 414. The mixed gas introduction hose 417 is fixedly installed on the regenerator 1. The mixed gas introduction hose 417 is fixedly connected to the rigid pipe 414.

[0073] In order to enable the mixed gas to be discharged from the air outlet pipe 410, in this mode, the end of the rotating pipe 404 is closed. The rotating pipe 404 is in communication with the inside of the sleeve 402. The rotating pipe 404 is in sealed contact with the fixed pipe 405.

[0074] In order to facilitate the collection of particulate impurities on the filter plate 409, in this embodiment, a support chassis 7 is fixedly arranged at the bottom of the regenerator 1, a door body 6 is installed on the outer side of the regenerator 1, a bottom hole is formed at the bottom of the regenerator 1, and the bottom of the vertical pipe 401 penetrates through the bottom hole.

[0075] In this embodiment

[0076] The mixed gas is introduced through the vertical pipe 401 and the mixed gas inlet hose 417, and then introduced into the vertical pipe 401 through the hard pipe 414. The particulate impurities in the mixed gas are filtered by the filter plate 409 in the sleeve 402, and then the mixed gas can be purified. The purified mixed gas is discharged through the gas outlet pipe 410.

[0077] During the vertical reciprocating movement of the vertical pipe 401, the sleeve 402 can be driven to move vertically reciprocally, and then the rotating pipe 404 and the fixed pipe 405 can be driven to move vertically reciprocally. Due to the meshing of the connecting gear 411 and the toothed plate 413, the rotating pipe 404 can also rotate back and forth during the vertical reciprocating movement. Then the rotating pipe 404 can drive multiple groups of air outlet holes 406 to rotate back and forth. When the air outlet holes 406 and the gas outlet pipe 410 are fully connected, the flow rate of the mixed gas is the smallest at this time. When the air outlet holes 406 slowly rotate, the connected part between the air outlet holes 406 and the gas outlet pipe 410 first decreases and then increases, and so on. In this way, the discharge speed of the mixed gas can always change. The mixed gas blows towards the catalyst below, and this process can also make the mixed gas fully contact with the catalyst, improving the regeneration efficiency of the catalyst.

[0078] During the back-and-forth rotation of the rotating pipe 404, the L-shaped rod 407 can be driven to drive the knocking head 408 to rotate back and forth, knocking on the filter plate 409. In this way, it can effectively prevent particulate impurities from adhering to the filter plate 409, improving the filtration efficiency. And when the catalyst is no longer regenerated later, the solenoid valve 1 415 can be opened and the solenoid valve 2 416 can be closed. During the knocking process of the filter plate 409, the particulate impurities can fall through the vertical pipe 401.

[0079] Compared with the related art, the high-efficiency regeneration air purification and energy-saving device of the propane-isobutane mixed dehydrogenation device provided by the present invention has the following beneficial effects:

[0080] During the vertical reciprocating movement of the vertical pipe 401, through the meshing of the connecting gear 411 and the toothed plate 413, the rotating pipe 404 can rotate back and forth during the vertical reciprocating movement. Furthermore, the rotating pipe 404 can drive multiple groups of air outlet holes 406 to rotate back and forth. When all the air outlet holes 406 are connected to the air outlet pipe 410, the flow rate of the mixed gas is the smallest at this time. When the air outlet holes 406 slowly rotate, the connected part between the air outlet holes 406 and the air outlet pipe 410 first decreases and then increases, and so on. In this way, the discharge speed of the mixed gas can always change. The mixed gas blows downward onto the catalyst. This process can also make the mixed gas fully contact with the catalyst, improve the efficiency of catalyst regeneration, and during this process, the particulate impurities on the filter plate 409 can be well cleaned, ensuring the purification effect of the mixed gas, and no manual cleaning is required in the later stage.

[0081] Third Embodiment

[0082] Based on the high-efficiency regeneration air purification and energy-saving device for the propane-isobutane mixed dehydrogenation device provided in the first and second embodiments of the present application, the third embodiment of the present application proposes another high-efficiency regeneration air purification and energy-saving device for the propane-isobutane mixed dehydrogenation device. The third embodiment is merely a preferred mode of the first embodiment or the second embodiment, and the implementation of the third embodiment will not affect the individual implementation of the first embodiment or the second embodiment.

[0083] The following further describes the third embodiment of the present invention in conjunction with the drawings and embodiments.

[0084] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 14 and Figure 15, the driving mechanism 5 includes a top frame 501, a power motor 502, a first full gear 503, a first rotating shaft 504, a screw rod 505, a sleeve disc 506, a torsion spring 507, a second rotating shaft 508, a guide rod 509, a partial gear 510, a second full gear 511, an auxiliary frame 512, a hydraulic cylinder 513 and a push plate 514. The top frame 501 is fixedly installed at the top of the regenerator 1. The power motor 502 is fixedly installed on the top frame 501. The output end of the power motor 502 is fixedly connected to the first full gear 503. The first rotating shaft 504 is rotatably installed on the top frame 501. The screw rod 505 is fixedly installed at the bottom of the first rotating shaft 504. The sleeve disc 506 is fixedly sleeved outside the first rotating shaft 504. The torsion spring 507 is fixedly installed between the sleeve disc 506 and the top frame 501. The bottom of the second rotating shaft 508 is fixedly connected to the guide rod 509. The guide rod 509 is vertically slidably installed on the first rotating shaft 504. The partial gear 510 and the second full gear 511 are both fixedly sleeved outside the second rotating shaft 508. The first full gear 503 meshes with the partial gear 510. The auxiliary frame 512 is fixedly installed at the top of the top frame 501. The hydraulic cylinder 513 is fixedly installed on the auxiliary frame 512. The hydraulic rod of the hydraulic cylinder 513 is fixedly connected to the push plate 514. The second rotating shaft 508 is rotatably installed at the bottom of the push plate 514. A gear notch 515 is provided on the first full gear 503.

[0085] In order to facilitate the meshing of the first full gear 503 with the second full gear 511 and the partial gear 510, in this mode, the second full gear 511 is located below the partial gear 510.

[0086] In order to facilitate the vertical movement of the second rotating shaft 508 relative to the first rotating shaft 504, in this mode, two guide holes are opened at the top of the first rotating shaft 504, and the guide rod 509 is slidably installed in the guide holes.

[0087] In this embodiment

[0088] First, the first full gear 503 meshes with the partial gear 510. The power motor 502 is started, and the power motor 502 drives the first full gear 503 to rotate. The first full gear 503 drives the partial gear 510 to rotate. The partial gear 510 drives the second rotating shaft 508 to rotate. The second rotating shaft 508 drives the first rotating shaft 504 to rotate through the guide rod 509. The first rotating shaft 504 drives the sleeve disc 506 to rotate. The sleeve disc 506 squeezes the torsion spring 507. At the same time, the first rotating shaft 504 drives the screw rod 505 to rotate. When the screw rod 505 rotates, it can be threadedly connected to the thread groove on the vertical rod 403, causing the vertical rod 403 to move upward. Furthermore, the vertical pipe 401 can be moved upward. Since there is a gear notch 515 on the first full gear 503, when the first full gear 503 is not meshed with the partial gear 510, at this time, the partial gear 510 is just at the position of the gear notch 515. When the first full gear 503 is not meshed with the partial gear 510, at this time, the torsion spring 507 resets and drives the first rotating shaft 504 to reverse. Furthermore, the screw rod 505 can be rotated in the reverse direction, so that the vertical rod 403 can move downward, and thus the vertical pipe 401 can move downward. In this way, the vertical reciprocating movement of the vertical pipe 401 in the vertical direction is realized.

[0089] When it is necessary to move the vertical pipe 401 upward, the hydraulic cylinder 513 can be started. The hydraulic cylinder 513 drives the push plate 514 to move upward. The push plate 514 drives the second rotating shaft 508 to move upward. The second rotating shaft 508 can drive the partial gear 510 and the second full gear 511 to move upward, causing the partial gear 510 to separate from the first full gear 503 and the second full gear 511 to mesh with the first full gear 503. At this time, when the power motor 502 is started, the first full gear 503 drives the second full gear 511 to rotate, and thus the vertical pipe 401 can be continuously moved upward until it reaches the specified position. The switching is relatively convenient.

[0090] Compared with the related technology, the high-efficiency regeneration air purification and energy-saving device of the propane isobutane mixed dehydrogenation device provided by the present invention has the following beneficial effects:

[0091] The positions of the partial gear 510 and the second full gear 511 can be quickly adjusted, so that the meshing relationship between the first full gear 503 and the partial gear 510 and the second full gear 511 can be switched. When the first full gear 503 meshes with the partial gear 510, due to the existence of the gear notch 515, when the first full gear 503 rotates, the vertical pipe 401 can reciprocate in the vertical direction. When the first full gear 503 meshes with the second full gear 511, at this time, the vertical pipe 401 can be continuously moved upward, and different states can be switched for use.

[0092] The above has introduced in detail the high-efficiency regeneration air purification and energy-saving device for the propane-isobutane mixed dehydrogenation unit provided by the present invention. Specific embodiments are applied in this article to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
