Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of hydrogen purification, and in particular to hydrogen purification equipment used for hydrogen production by methanol reforming. Background Art
[0002] Hydrogen purification equipment usually uses a variety of technologies and equipment to remove impurities in hydrogen to obtain high-purity hydrogen. Adding catalysts to the methanol reforming hydrogen production process can significantly improve the efficiency and rate of the reaction; common catalysts used in methanol reforming hydrogen production reactions include copper-based catalysts, such as a combination of copper oxide and zinc oxide. This type of catalyst can reduce the activation energy of the reaction and promote the decomposition of methanol and the production of hydrogen.
[0003] In the prior art, purification work usually consists of catalyst conveying equipment, fluidized bed reactor, air flow conveying equipment or mechanical stirring equipment; when adding the catalyst, first, the granular / powdered catalyst is pretreated, and then the pretreated catalyst is passed through a special feeding device, such as a screw conveyor, so as to evenly disperse the catalyst into the fluidized bed reactor, and by means of air flow conveying or mechanical stirring, the catalyst is ensured to be evenly distributed in the reactor, thereby completing the purification work; In the prior art, granular / powdered catalysts often encounter blockages during transportation. First, production is interrupted, which will cause the entire production process to stagnate, affect product delivery, and cause economic losses. Second, blockages will cause the catalyst to accumulate locally and stay in an unfavorable environment for a long time, resulting in reduced activity and selectivity, and impaired performance. In addition, blockages cause the internal pressure of the pipeline to rise sharply, exceeding the equipment's tolerance limit, resulting in pipeline ruptures, loosening of connecting parts, and even overall damage to the equipment. In addition, frequent blockages require frequent cleaning and maintenance, which increases manpower, material and time costs. In addition, when conveying catalysts, the screw shaft is often deformed due to overload or manufacturing defects. Since operators cannot directly observe the internal conditions of the conveying pipeline, the deformation of the screw shaft causes uneven clearance between the spiral blades and the inner wall of the pipeline, hindering the advancement of materials, reducing the conveying speed and volume, resulting in poor conveying effect and slowing down efficiency. At the same time, the deformed screw shaft will produce noise due to abnormal contact and friction with the inner wall of the pipeline when rotating, and accelerate the wear of the pipeline and the screw shaft itself, greatly shortening their service life, increasing the frequency and cost of repair and replacement of parts, and affecting the continuity and stability of production. In addition, the existing conveying devices lack effective thermal insulation measures during the material conveying process. Some catalysts, such as copper-based catalysts such as copper oxide and zinc oxide, are easily affected by temperature. At the same time, the noise is relatively loud, affecting the working environment. The materials are prone to scaling and clogging the pipeline, affecting the conveying efficiency and the normal operation of the equipment.

[0016] Compared with the prior art, the present invention provides a hydrogen purification device for use in methanol reforming hydrogen production, which has the following beneficial effects: 1. The anti-clogging multi-adjustment component can effectively prevent the main double-layer pipeline from being blocked when the spiral conveyor is used to transport the catalyst for purification. Different from the prior art, it does not need to be dismantled like the existing equipment or the cumbersome operation of blocking through a special unblocking port. The catalyst will not accumulate locally for too long, resulting in reduced activity and selectivity and impaired performance.

[0017] 2. By setting the detection piece in the detection channel, it is possible to effectively judge whether the spiral conveyor is deformed based on whether the detection piece can slide back and forth in the detection channel; it effectively avoids the situation where relevant personnel cannot know the deformation of the spiral conveyor in time, resulting in uneven gap between the spiral blades and the main double-layer pipe, which causes the material to be blocked, reduces the conveying speed and conveying volume, and has poor conveying effect and reduced efficiency. The overall setting of the spiral conveyor shaft deformation detection component provides strong support for the continuity and stability of production.
[0018] 3. The main double-layer pipe can provide a working environment for the catalyst material. The cavity of the pipe is different from the existing single-layer pipe. This setting can be used for materials that need to be transported under specific temperature conditions, such as high-temperature clinker and perishable materials that need to be kept at low temperature. The double-layer structure can effectively reduce the loss or absorption of heat and keep the temperature of the material stable. In addition, it can effectively prevent the generation of static electricity, reduce the accumulation of static electricity caused by friction during the transportation of powdered catalysts, reduce the risk of static electricity discharge, and avoid possible safety accidents such as fire or explosion; Moreover, the noise generated by the friction and collision between the material and the inner wall of the pipe during transportation will be absorbed and blocked by the air layer in the double-layer structure, thereby reducing the noise level in the working environment; At the same time, good thermal insulation performance helps to maintain the temperature stability of the catalyst during transportation. For temperature-sensitive catalyst reactions, it can maintain its activity and performance, ensuring efficient reaction. In addition, the temperature of the double-layer pipe is more stable, which can reduce the scaling and adhesion of materials caused by temperature changes, avoid viscosity and humidity changes caused by temperature changes, and reduce the possibility of blockage.

[0032] For further examples, please refer to Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown: The spiral conveyor shaft deformation detection component 5 is used to perform deformation detection on the spiral conveyor 3 for conveying materials, so as to avoid the situation in which the material advancement is blocked, the conveying speed and conveying volume are reduced, the conveying effect is poor, the efficiency is slowed down, and the continuity and stability of production are affected after the spiral conveyor shaft deformation detection component 5 occurs; the spiral conveyor shaft deformation detection component 5 includes a convex ball 501 equidistantly fixedly connected to the I-shaped ring A402, a medium conveying cavity 502 is fixedly connected in the inner cavity of the main double-layer pipe 2, an electromagnet 503 is fixedly connected to the top of the inner cavity of the medium conveying cavity 502, a spring 504 is fixedly connected to the bottom surface of the electromagnet 503, and a push rod is fixedly connected to the end of the spring 504 away from the electromagnet 503 An air piston rod 505, an air inlet 506 is provided at the bottom of the medium conveying cavity 502, an air pipe 507 is fixedly connected to one side of the top of the medium conveying cavity 502, a detection channel 508 is horizontally provided on the spiral conveying member 3, a detection piece 509 is slidably connected in the detection channel 508, blocking rings 510 are symmetrically fixedly connected at both ends of the spiral conveying member 3, a rope 511 is fixedly connected to the detection piece 509, a fixing bar 512 is equidistantly fixedly connected to the moving piece 409, an annular support ring 513 is fixedly connected to the fixing bar 512, an electric winding ring 514 is fixedly connected to the annular support ring 513 through a motor, and one end of the rope 511 is wound around the electric winding ring 514.
[0033] in: The screw conveyor shaft deformation detection component 5 is mainly used to perform deformation detection on the screw conveyor 3 for conveying materials, so as to avoid deformation due to overload conveying or manufacturing defects, resulting in uneven gap between the spiral blades and the inner wall of the pipe, obstruction of material advancement, reduction of conveying speed and conveying volume, poor conveying effect, slow efficiency, and affecting the continuity and stability of production.
[0034] The piston plate surface on the air push piston rod 505 is made of magnetic material and is mainly used in conjunction with the electromagnet 503. When the deformation of the non-spiral conveyor 3 is detected, the electromagnet 503 will adsorb the air push piston rod 505 to prevent the air push piston rod 505 from being located in the I-shaped ring B404 and hindering its anti-blocking processing work.
[0035] The detection sheet 509 is slidably fitted with the detection channel 508 .
[0036] The blocking ring 510 is mainly used to prevent the detection piece 509 from moving out of the pipeline during movement.
[0037] The electric winding ring 514 is driven by a motor.
[0038] Everything in the above example works like this: It should be noted that the anti-blocking multi-adjustment component 4 and the screw conveyor shaft deformation detection component 5 will not work at the same time, and only one of them will work at each time.
[0039] The following is the working process of the anti-blocking multi-adjustment component 4: It should be noted that: if the main double-layer pipe 2 is not blocked, the I-shaped ring B404 is in a non-tilted state. Only when the main double-layer pipe 2 conveys the catalyst at a slow speed, the master control of the device will control the equipment to adjust the tilt angle of the I-shaped ring B404, so that the semicircular block 406 on it pushes the moving piece 409; and at this time, the push piston rod 505 is adsorbed by the electromagnet 503. The details are as follows: During use, if the main double-layer pipe 2 is blocked, the operator only needs to rotate the adjusting screw 407, and the rotating adjusting screw 407 will move the disc 408 thereon. Since the disc 408 is movably mounted in the I-shaped ring A402, the moving disc 408 will move toward the moving piece 409 with the help of the auxiliary strip provided on the rotating main body 401. Please refer to the attached Figure 7As it is known that the I-shaped ring A402 and the I-shaped ring B404 are connected by the connecting rod 403, the I-shaped ring B404 can rotate with the shaft 405 as the rotation axis. Therefore, during the movement of the I-shaped ring A402, the I-shaped ring B404 will rotate with the shaft 405 as the rotation axis. As the I-shaped ring B404 rotates, the I-shaped ring B404 on the shaft 405 will gradually tilt and approach the moving piece 409. Further, as the rotating body 401 is driven by the motor to rotate, the inclined semicircular block 406 on the rotating body 401 will first push the moving piece 409 during the rotation. At this time, the moving moving piece 409 will move in a direction away from the rotating body 401 with the driving member 410 and the spiral conveying member 3 having a fixed connection relationship. At this time, the auxiliary circular ring piece A411 and the auxiliary circular ring piece B412 serve as supports for the lateral movement of the spiral conveyor 3, and the telescopic rod 414 is compressed. Furthermore, as the part close to the moving piece 409 leaves the moving piece 409, the originally compressed telescopic rod 414 will move with the moving piece 409 in the direction close to the rotating body 401 during recovery; in this reciprocating manner, the spiral conveyor 3 will perform a linear reciprocating motion in the main double-layer pipe 2, thereby loosening the material blocked in the gap between the spiral conveyor 3 and the main double-layer pipe 2, thereby restoring the spiral conveyor 3 to the material conveying work; further, after the blockage problem is solved, the operator can reversely rotate the adjusting screw 407 to restore the I-shaped ring B404 in the inclined working state to a non-working vertical state; Furthermore, by setting up the anti-clogging multi-adjustment component 4, it is possible to effectively avoid the situation where the spiral conveyor 3 causes the main double-layer pipeline 2 to be blocked when conveying the catalyst for purification operation. Different from the prior art, it does not need to be dismantled like the existing equipment or the cumbersome operation of blocking treatment from a special unblocking port can be completed. The catalyst will not accumulate locally for too long, resulting in reduced activity and selectivity, and impaired performance. In addition, there will be no situation where the internal pressure of the main double-layer pipeline 2 rises sharply due to blockage, exceeding the equipment's tolerance limit, resulting in pipeline rupture, loosening of connecting parts, or even overall damage to the equipment.
[0040] Furthermore, the main double-layer pipe 2 can provide a working environment for the catalyst material to be transported; the existence of the pipe cavity is different from the existing single-layer pipe. This arrangement can be used for materials that need to be transported under specific temperature conditions, such as high-temperature clinker, perishable materials that need to be kept at a low temperature, etc. The double-layer structure can effectively reduce the loss or absorption of heat and keep the temperature of the material stable; In addition, the setting of the main double-layer pipe 2 cavity can effectively prevent the generation of static electricity, reduce the accumulation of static electricity generated by friction during the transportation of powdered catalyst, reduce the risk of static electricity discharge, and avoid possible safety accidents such as fire or explosion; Moreover, the noise generated by the friction and collision between the material and the inner wall of the pipe during transportation will be absorbed and blocked by the air layer in the double-layer structure, thereby reducing the noise level in the working environment; At the same time, good thermal insulation performance helps to maintain the temperature stability of the catalyst during transportation. For temperature-sensitive catalyst reactions, it can maintain its activity and performance, ensuring efficient reaction. In addition, the temperature of the double-layer pipe is more stable, which can reduce the scaling and adhesion of materials caused by temperature changes, avoid viscosity and humidity changes caused by temperature changes, and reduce the possibility of blockage.
[0041] Please refer to the above working process Figure 1 , Figure 2 , Figure 4 , Figures 6 to 9 .
[0042] The following is the working process of the screw conveyor shaft deformation detection component 5: During use, during this working process, the electromagnet 503 is not energized to magnetically attract the air piston rod 505, and the I-shaped ring B404 does not tilt at this time. For further information, please refer to the attached Figure 5 When the spiral conveyor 3 is being tested for deformation, the rotating body 401 is started, and the rotating body 401 will rotate with the I-shaped ring B404. During the rotation of the I-shaped ring B404, the convex ball 501 on the I-shaped ring B404 will come into contact with and move away from the air push piston rod 505. During this process, the air push piston rod 505 will move up and down in the medium conveying cavity 502 with the assistance of multiple convex balls 501 arranged at equal distances and the spring 504. At this time, the air inlet 506 is used for gas conveying, and further When the air-pushing piston rod 505 moves in the medium conveying cavity 502, the pushed gas in the medium conveying cavity 502 will enter the closed cavity between the auxiliary annular piece A411 and the moving piece 409 through the air pipe 507. Further, as the gas gradually increases, the detection piece 509 in the detection channel 508 will be pushed. At this time, the operator can judge whether the spiral conveying member 3 is deformed by whether the detection piece 509 can move to the other end in the detection channel 508, that is, the end where the telescopic rod 414 is located; When the detection work is finished, the electric winding ring 514 on the annular support ring 513 is started to reset the detection piece 509 moved to one end of the telescopic rod 414; Furthermore, by setting the detection piece 509 in the detection channel 508, it is possible to effectively judge whether the spiral conveyor 3 is deformed based on whether the detection piece 509 can slide back and forth in the detection channel 508; it is effectively avoided that the relevant personnel are unable to know the deformation of the spiral conveyor 3 in time, resulting in uneven gaps between the spiral blades and the main double-layer pipe 2, which in turn causes obstruction in the advancement of materials, reduces the conveying speed and conveying volume, and results in poor conveying effect and reduced efficiency. The overall setting of the spiral conveyor shaft deformation detection component 5 provides strong support for the continuity and stability of production.
