Description

Technical Field

[0001] The invention relates to the technical field of desulfurization equipment, and in particular to a purification treatment device for producing sustainable aviation fuel. Background Art

[0002] With the rapid development of the global aviation industry, the demand for aviation fuel continues to rise. However, the use of traditional fossil fuels not only faces the threat of depletion of non-renewable resources, but also brings a series of problems such as greenhouse gas emissions and environmental pollution, which has a profound impact on global climate change. In order to meet these challenges, the development of sustainable aviation fuel (SAF) has become one of the key research directions of the aviation industry. Sustainable aviation fuel uses biomass, waste or other renewable resources as raw materials, which can effectively reduce dependence on fossil resources and significantly reduce carbon emissions. However, the production process of SAF is complicated, especially in the process of converting raw materials into fuel, which is often accompanied by the generation and residue of impurities. These impurities include sulfides, nitrides, metal ions and oxygen-containing compounds, which not only reduce the purity and performance of the fuel, but also may cause corrosion or blockage to subsequent processing equipment, and even threaten the safe operation of aircraft engines. Therefore, how to efficiently remove impurities and ensure fuel quality has become an important link in the SAF production process.

[0003] At present, purification treatment technologies mainly include chemical precipitation, distillation and adsorption. Among them, adsorption technology has been widely used due to its high efficiency, energy saving and environmental protection. Through functionalized or customized adsorbents, selective removal of specific impurities can be achieved. In addition, the adsorption process is usually carried out under mild conditions, without the need for high temperature and high pressure, avoiding excessive energy consumption. At the same time, the adsorbent can be recycled through regeneration, reducing secondary pollution.

[0004] However, existing purification devices often face the problem of uneven adsorbent loading, that is, the upper layer of adsorbent is saturated faster due to direct contact with high-concentration impurities, while the lower layer of adsorbent is not fully utilized. Especially in the desulfurization process, the upper layer of adsorbent is more easily saturated due to the preferential adsorption of sulfides, resulting in a decrease in purification efficiency. If the upper layer of adsorbent is saturated and blocked, it will not only affect the overall desulfurization effect, but may also force the entire device to stop running early to replace the adsorbent, increasing maintenance costs and reducing the operating stability of the device. Therefore, how to solve the problem of uneven adsorbent load distribution and optimize the desulfurization effect has become an important research direction for improving the performance of purification devices. Summary of the invention

[0007] Preferably, the adjustment component includes a gear a disposed at the bottom of the desulfurization tower, and a connecting shaft extending into the connecting sleeve and connected to the spiral blade is rotatably connected to the partition, and a gear b adapted to the gear a is provided at the bottom of the connecting shaft.

[0008] Preferably, the bottom of the connecting shaft is slidably connected to a sliding shaft, the gear b is connected to the sliding shaft, a top contact piece is connected to the sliding shaft, and the bottom of the desulfurization tower is connected to a top contact boss.

[0009] Preferably, a spring a is provided between the sliding shaft and the connecting shaft.

[0010] Preferably, the bottom of the connecting sleeve is slidably connected to a connecting pipe, the connecting port is opened on the connecting pipe, the bottom of the connecting pipe is connected to the partition, the bottom of the partition is connected to an annular boss, the connecting shaft is connected to an annular frame, the annular frame is rotatably connected to a roller in contact with the annular boss, the bottom of the desulfurization tower is rotatably connected to a turntable, the purification chamber is connected to the turntable, and a spring telescopic rod is connected between the annular boss and the turntable.

[0011] Preferably, a bracket is provided in the desulfurization chamber, and the connecting sleeve is connected to the bracket.

[0012] Preferably, the desulfurization tower is rotatably connected to a rotating shaft, the rotating shaft is connected to the purification chamber, the rotating shaft is connected to a lead screw b, a sliding disk is threadedly connected to the lead screw b, a fixed disk is connected to the top of the desulfurization tower, the sliding disk is slidably connected to the fixed disk, a pressure rod is connected to the bottom of the sliding disk, a rotating disk is slidably connected to the rotating shaft, a spring b is provided between the rotating disk and the rotating shaft, a connecting rod is connected to the bottom of the rotating disk, a transmission disk is connected to the purification chamber, and a transmission groove is provided on the top of the transmission disk.

[0013] Preferably, the bottom of the desulfurization tower is connected to a base, the base is connected to a motor, the gear a is connected to the drive shaft of the motor, and the rotating shaft is connected to the drive shaft of the motor.

[0014] Preferably, a collecting pipe is connected to the top of the base, and the oil outlet pipe is connected to the collecting pipe.

[0015] Preferably, a baffle is connected to the top of the purification chamber.

[0016] This application, through the above technical solution, solves the problems of uneven adsorbent loading and oversaturation in the prior art, and significantly improves the purification effect and stability of the desulfurization device. Specifically: By dividing the purification chamber into multiple desulfurization chambers and adjusting the components to flexibly change the positions of the desulfurization chambers, the desulfurization chambers can be used in turn, so that each desulfurization chamber can obtain a balanced load distribution during long-term use. This design avoids excessive saturation of the adsorbent due to a long-term high-load state in a certain desulfurization chamber, ensuring the efficiency of the adsorbent use during the desulfurization process.

[0017] Each desulfurization chamber is equipped with a spiral blade. The rotation of the spiral blade not only plays the role of conveying the adsorbent, but also can effectively stir and push the adsorbent, thereby promoting the uniform distribution of the adsorbent. During the rotation of the spiral blade, the adsorbent particles will be rearranged, thereby improving the adsorption efficiency of the adsorbent. This process effectively avoids the problem of local oversaturation of the adsorbent during use, and ensures the uniform use of the adsorbent in each desulfurization chamber.

[0018] In this application, an oil outlet pipe is provided to ensure that the oil can be discharged from the desulfurization chamber in time, and to prevent the retained oil from stagnating for a long time in the desulfurization chamber. During the non-desulfurization operation period, the rotation of the spiral blades can also promote the flow of the oil through physical stirring, which is helpful for the discharge of the retained oil and avoids the pollution or reduced purification effect caused by the long-term retention of the oil. In this way, the desulfurization device can maintain long-term stable operation.

[0019] When the connecting shaft and the spiral blade rotate, the roller on the annular frame contacts the annular boss, and the rotation of the turntable can make the partition vibrate up and down. This vibration effect helps to improve the mixing and uniform distribution of the adsorbent in the desulfurization chamber. This vibration can not only avoid uneven deposition of the adsorbent, but also break the particle aggregation that may be formed by the adsorbent, thereby improving the adsorption effect. In addition, the vibration can generate a certain force to help the adsorbent particles overcome gravity and friction, so that they can flow more smoothly in the desulfurization tower. Under the action of vibration, the adsorbent particles will be slightly loosened, making it easier for them to enter the connection port through the connecting pipe. As the spiral blade rotates, the adsorbent particles are transported to various areas of the desulfurization tower to achieve uniform distribution, thereby improving the desulfurization efficiency and adsorption effect. The synergistic effect of vibration and spiral blades ensures uniform flow and effective transportation of the adsorbent, avoiding the decrease in desulfurization efficiency caused by uneven distribution of the adsorbent. In addition, the force generated by vibration can promote the flow of oil and reduce the retention and viscosity of oil in the desulfurization tower. When vibration acts on the partition, the up and down vibration of the partition helps the oil to overcome the resistance between the partition and the oil, so that it can smoothly pass through the connecting pipe into the oil outlet pipe. The vibration can not only improve the fluidity of the oil, but also prevent the oil from accumulating in the desulfurization tower, thereby avoiding the problem of efficiency reduction or pollution caused by oil retention.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] refer to Figure 1-Figure 8 , a purification treatment device for producing sustainable aviation fuel, comprising: Desulfurization tower 100; A purification chamber 101 is provided in the desulfurization tower 100, and the purification chamber 101 has a plurality of desulfurization chambers 102. A top cover 103 is connected to the top of the desulfurization tower 100, and an oil inlet 104 communicating with one of the desulfurization chambers 102 is provided on the top cover 103; A partition 105 is disposed in the desulfurization chamber 102, and a plurality of small holes are opened on the partition 105 for carrying the adsorbent and passing the oil; A plurality of oil outlet pipes 106 provided on the desulfurization tower 100 are connected to the desulfurization chamber 102; A connecting sleeve 107 is provided on the partition 105, a spiral blade 108 is provided in the connecting sleeve 107, and a connecting port 109 is provided at the bottom of the connecting sleeve 107; An adjustment component disposed between the desulfurization tower 100 and the desulfurization chamber 102 is used to rotate the spiral blades 108 in the desulfurization chamber 102 to adjust the position of the adsorbent in the desulfurization chamber 102 after the desulfurization operation; The adjusting component can also rotate the purification chamber 101 by a preset angle when the spiral blade 108 rotates a preset number of times, and adjust the position of the desulfurization chamber 102 so that an adjacent desulfurization chamber 102 is connected to the oil inlet 104; Wherein, the adjusting component does not rotate the spiral blade 108 in a desulfurization chamber 102 connected to the oil inlet 104;By setting up the purification chamber 101, the operator can fill multiple desulfurization chambers 102 in the purification chamber 101 with solid adsorbents such as zinc oxide adsorbents and molecular sieve adsorbents, and introduce the fuel oil liquid that needs to be desulfurized and purified into one of the desulfurization chambers 102 from the oil inlet 104. When the oil liquid passes through the adsorbent filled in the desulfurization chamber 102, the sulfide (such as hydrogen sulfide, mercaptan, etc.) in the oil liquid contacts the surface of the adsorbent filled in the desulfurization chamber 102. Taking the commonly used adsorbent such as zinc oxide as an example, when hydrogen sulfide contacts zinc oxide, a chemical reaction occurs to generate zinc sulfide (ZnS), H2S + ZnO → ZnS + H2O. This process not only removes hydrogen sulfide, but also converts it into chemically stable solid zinc sulfide, which is fixed on the surface of the adsorbent, thereby achieving efficient removal of hydrogen sulfide. The purified oil liquid can enter the oil outlet pipe 106 through the small hole on the partition 105 and be discharged to complete the fuel purification. Specifically, the operator can start the adjustment component to rotate the spiral blades 108 in the multiple desulfurization chambers 102. When the spiral blades 108 are rotated for a preset number of turns, the purification chamber 101 can be rotated by a preset angle, and the position of the desulfurization chamber 102 is adjusted so that a desulfurization chamber 102 adjacent to the desulfurization chamber 102 in the rotation direction is connected to the oil inlet 104, and the fuel oil can enter the new desulfurization chamber 102 to continue desulfurization and purification. At this time, the spiral blades 108 in the desulfurization chamber 102 currently connected to the oil inlet 104 do not rotate. After the purification work, the spiral blade 108 in the desulfurization chamber 102 begins to rotate. During this process, the spiral blade 108 can be used to rotate and transport materials. The adsorbent entering the connection port 109 at the bottom of the desulfurization chamber 102 can be transported upward along the connecting sleeve 107 and discharged from the top of the connecting sleeve 107, gradually bringing the adsorbent below to the top of the desulfurization chamber 102. As the adsorbent below the desulfurization chamber 102 gradually decreases, the adsorbent above it gradually fills the bottom of the desulfurization chamber 102 under the action of gravity, thereby achieving the redistribution of the adsorbent in the desulfurization chamber 102. This process not only effectively avoids the problem of local oversaturation of the adsorbent after long-term use, but also plays a good mixing role. Since the spiral blade 108 will continuously stir and push the adsorbent during the process of transporting the adsorbent, this helps to rearrange and evenly distribute the particles inside the adsorbent, so that the adsorbent is maximized. Through this mixing effect, it is possible to avoid excessive consumption of some adsorbents due to long-term fixed contact with oil. In addition, the purification chamber 101 is divided into a plurality of desulfurization chambers 102. During the desulfurization operation, as the adjustment components work, the plurality of desulfurization chambers 102 can process the oil in turn. That is, before a desulfurization chamber 102 reaches the oil inlet 104 again after the desulfurization operation, it will undergo multiple position changes. During this process, the spiral blades 108 are given sufficient rotation working time. Each rotation can help the adsorbent to be more evenly distributed in the chamber, avoiding uneven deposition of the adsorbent.At the same time, it can ensure that the workload of each desulfurization chamber 102 is reasonably distributed, prevent a certain desulfurization chamber 102 from being in an overload state for a long time, and ensure that the adsorbent in each desulfurization chamber 102 will not lose its desulfurization capacity due to long-term saturation. Through this rotation and position change mechanism, the use efficiency of the adsorbent can be maximized within a desulfurization cycle, and the economy and sustainability of the desulfurization operation can be improved. Among them, the spiral blade 108 in the desulfurization chamber 102 currently connected to the oil inlet 104 is not rotated, the purpose is to disturb the adsorbent as little as possible during the desulfurization work. The main purpose of this design is to maintain the stability and effectiveness of the adsorbent in the desulfurization chamber 102. During the desulfurization process, the surface of the adsorbent will react chemically with the sulfide in the oil to generate stable compounds (such as zinc sulfide). If the spiral blade 108 rotates during the desulfurization process, it will cause violent movement or disturbance of the adsorbent, which may cause uneven distribution of the adsorbent, thereby affecting the desulfurization effect. The non-rotating spiral blade 108 can avoid unnecessary disturbance to the adsorbent, thereby ensuring that it is always in the best adsorption state during the entire desulfurization process. In addition, each desulfurization chamber 102 is connected to an oil outlet pipe 106. The purpose is that after each rotation of the purification chamber 101, even if some oil is retained in the desulfurization chamber 102, the rotation of the spiral blade 108 can effectively cause the adsorbent to be turned over, thereby effectively causing the retained oil to be discharged through the oil outlet pipe 106, thereby preventing the oil from staying in the desulfurization chamber 102 for a long time. The rotation of the spiral blade 108 not only helps to evenly mix and redistribute the adsorbent, but also promotes the flow of the oil through physical stirring, ensuring that the retained oil is discharged in time. This design can reduce the pollution caused by oil stagnation or the reduction of treatment effect, and ensure the continuous fluidity of the oil, thereby maintaining the efficient operation of the system.

[0024] As a further solution of the present invention, the adjustment component includes a gear a200 disposed at the bottom of the desulfurization tower 100, a connecting shaft 201 extending into the connecting sleeve 107 and connected to the spiral blade 108 is rotatably connected to the partition 105, and a gear b202 adapted to the gear a200 is disposed at the bottom of the connecting shaft 201; By setting the gear a200, the rotation of the spiral blade 108 in the desulfurization tower 100 can be controlled by rotating the gear a200 and meshing the gear a200 with the gear b202. When the gear a200 rotates, the connecting shaft 201 is driven to rotate, so that the connecting shaft 201 is connected to the spiral blade 108 and transmits power to realize the rotation of the spiral blade 108. The purpose of this design is to adjust the rotation state of the spiral blade 108 through mechanization. It can turn over and distribute the adsorbent after the desulfurization work, ensuring the desulfurization efficiency and the effective use of the adsorbent.

[0025] As a further solution of the present invention, the bottom of the connecting shaft 201 is slidably connected with a sliding shaft 203, the gear b202 is connected to the sliding shaft 203, the sliding shaft 203 is connected with a top contact piece 204, and the bottom of the desulfurization tower 100 is connected with a top contact boss 205; As a further solution of the present invention, a spring a206 is provided between the sliding shaft 203 and the connecting shaft 201; By setting the above structure, when the desulfurization chamber 102 rotates to the position connected to the oil inlet 104, the fixed top contact boss 205 can squeeze the top contact piece 204, so that the top contact piece 204 drives the sliding shaft 203 to move downward. This process will cause the gear b202 on the sliding shaft 203 to disengage from the gear a200, thereby achieving the spiral blade 108 in the desulfurization chamber 102 connected to the oil inlet 104 without rotating. In this way, the spiral blade 108 in the desulfurization chamber 102 in the desulfurization working state stops rotating, avoiding the disturbance of the adsorbent when the oil enters the desulfurization chamber 102, ensuring that the adsorbent maintains the best adsorption state. For other desulfurization chambers 102 that are not in desulfurization work, the spiral blade 108 will continue to rotate to mix and distribute the adsorbent, ensuring the desulfurization efficiency of each desulfurization chamber 102 and the uniform use of the adsorbent. After the subsequent desulfurization work of the desulfurization chamber 102 is completed, when the purification chamber 101 rotates, the top contact piece 204 can leave the top contact boss 205, and the sliding shaft 203 is reset under the action of the spring a206, so that the gear b202 is engaged with the gear a200 again, so that the spiral blade 108 can resume the rotation function and perform the redistribution and mixing operations of the adsorbent.

[0026] As a further solution of the present invention, the bottom of the connecting sleeve 107 is slidably connected with a connecting pipe 300, the connecting port 109 is opened on the connecting pipe 300, the bottom of the connecting pipe 300 is connected to the partition 105, the bottom of the partition 105 is connected with an annular boss 301, the connecting shaft 201 is connected with an annular frame 302, the annular frame 302 is rotatably connected with a roller 303 in contact with the annular boss 301, the bottom of the desulfurization tower 100 is rotatably connected with a turntable 304, the purification chamber 101 is connected to the turntable 304, and a spring telescopic rod 305 is connected between the annular boss 301 and the turntable 304; By setting the above structure, when the connecting shaft 201 and the spiral blade 108 rotate, the roller 303 on the annular frame 302 contacts the annular boss 301, and cooperates with the rotation of the turntable 304 to make the partition 105 vibrate up and down. This vibration effect helps to improve the mixing and uniform distribution of the adsorbent in the desulfurization chamber 102. This vibration can not only avoid uneven deposition of the adsorbent, but also break the particle aggregation that may be formed by the adsorbent, thereby improving the adsorption effect. In addition, the vibration can generate a certain force to help the adsorbent particles overcome gravity and friction, so that they can flow more smoothly in the desulfurization tower 100. Under the action of vibration, the adsorbent particles will be slightly loosened, making it easier to enter the connection port 109 through the connecting pipe 300. As the spiral blade 108 rotates, the adsorbent particles are transported to various areas of the desulfurization tower 100 to achieve uniform distribution, thereby improving the desulfurization efficiency and adsorption effect. The synergistic effect of vibration and spiral blades 108 ensures the uniform flow and effective transportation of the adsorbent, and avoids the decrease in desulfurization efficiency caused by uneven distribution of the adsorbent. In addition, the force generated by the vibration can promote the flow of the oil and reduce the retention and viscosity of the oil in the desulfurization tower 100. When the vibration acts on the partition 105, the up and down vibration of the partition 105 helps the oil to overcome the resistance between the partition 105 and the oil, so that it can smoothly pass through the connecting pipe 300 into the oil outlet pipe 106. The vibration effect can not only improve the fluidity of the oil, but also prevent the oil from accumulating in the desulfurization tower 100, thereby avoiding the problem of reduced efficiency or pollution caused by the retention of the oil.

[0027] As a further solution of the present invention, a bracket 306 is provided in the desulfurization chamber 102, and the connecting sleeve 107 is connected to the bracket 306; By setting the bracket 306 to fix the connecting sleeve 107 in the desulfurization chamber 102, the position of the connecting sleeve 107 can be effectively stabilized to prevent it from being deviated due to the vibration generated by the rotation of the spiral blade 108 or the impact force of the oil flow. The setting of the bracket 306 ensures that the connecting sleeve 107 is always in the correct working position, so that the delivery path of the adsorbent remains accurate.

[0028] As a further solution of the present invention, a rotating shaft 400 is rotatably connected to the desulfurization tower 100, the rotating shaft 400 is connected to the purification chamber 101, a lead screw b401 is connected to the rotating shaft 400, a sliding disk 402 is threadedly connected to the lead screw b401, a fixed disk 403 is connected to the top of the desulfurization tower 100, the sliding disk 402 is slidably connected to the fixed disk 403, a pressure rod 404 is connected to the bottom of the sliding disk 402, a rotating disk 405 is slidably connected to the rotating shaft 400, a spring b406 is provided between the rotating disk 405 and the rotating shaft 400, a connecting rod 407 is connected to the bottom of the rotating disk 405, a transmission disk 408 is connected to the purification chamber 101, and a transmission groove 409 is provided on the top of the transmission disk 408; By setting a lead screw b401, which is a reciprocating lead screw, when the motor 501 drives the gear a200 and the rotating shaft 400 to rotate, the lead screw b401 can rotate to move the position of the sliding disk 402 downward through the force of the thread, and the rotating disk 405 has a certain distance from the transmission disk 408 through the action of the spring b406. When the rotating shaft 400 rotates a preset full number of circles, when the sliding disk 402 moves downward to a preset position, the pressure rod 404 at its bottom can squeeze the position of the rotating disk 405, so that the rotating disk 405 moves downward. When the rotating disk 405 moves downward, the connecting rod 407 can be inserted into the transmission groove 409. As the rotating shaft 400 rotates, the purification chamber 101 can be rotated through the rotating disk 405, the connecting rod 407, the transmission groove 409 and the transmission disk 408. In this process, after the sliding plate 402 moves downward to the limit position, it starts to move upward to reset, so that the connecting rod 407 gradually leaves the transmission groove 409 and no longer contacts the side wall of the transmission groove 409. When the purification chamber 101 rotates and an adjacent desulfurization chamber 102 corresponds to the position of the oil inlet 104, the connecting rod 407 completely leaves the transmission groove 409. Thus, it returns to the initial state and is ready for the next rotation cycle. This structural design realizes the periodic rotation of the purification chamber 101 through the mutual cooperation of the lead screw b401 and the spring b406.

[0029] As a further solution of the present invention, a base 500 is connected to the bottom of the desulfurization tower 100, a motor 501 is connected to the base 500, a gear a200 is connected to the drive shaft of the motor 501, and a rotating shaft 400 is connected to the drive shaft of the motor 501; By setting the above structure, the motor 501 connects the gear a200 and the rotating shaft 400 through the driving shaft, thereby realizing the coordinated control of two functions: one is to drive the rotation of the spiral blade 108 through the meshing of the gear a200 and the gear b202; the other is to connect the purification chamber 101 through the rotating shaft 400 to drive the rotation of the purification chamber 101. When the motor 501 is started, the rotation of the gear a200 can be controlled, so that the power transmission to the spiral blade 108 is realized through the connecting shaft 201, so that it can stir, transport and evenly distribute the adsorbent. At the same time, by driving the rotation of the rotating shaft 400 by the motor 501, the purification chamber 101 can be driven to rotate as a whole, realizing the rotation operation of the desulfurization chamber 102.

[0030] As a further solution of the present invention, a manifold 502 is connected to the top of the base 500, and the oil outlet pipe 106 is connected to the manifold 502; By providing the manifold 502, the oil treated in each desulfurization chamber 102 can be collected in one place. The residual oil in the desulfurization chamber 102 in non-desulfurization operation can also be discharged into the manifold 502, which simplifies the processing flow.

[0031] As a further solution of the present invention, a baffle 110 is connected to the top of the purification chamber 101; By providing the baffle 110 , when the purification chamber 101 rotates, the baffle 110 can be used to close the oil inlet 104 , thereby preventing the oil in the oil outlet from entering the gap between each desulfurization chamber 102 when the purification chamber 101 rotates.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
