Description

Technical Field

[0001] The invention relates to the technical field of chemical equipment, in particular to a methanol-to-hydrogen converter with high sealing performance. Background Art

[0002] The methanol hydrogen converter is a device used to convert methanol and water into hydrogen. It uses a catalytic conversion process to crack methanol and convert it into hydrogen at a certain temperature. This equipment occupies a core position in the methanol hydrogen production system and plays a vital role in improving the production efficiency and quality of hydrogen.

[0003] In the methanol conversion hydrogen production process, the tank cover is a frequently operated component that needs to be opened before and after hydrogen production. Therefore, compared with other connection parts of the reactor, the joint area between the tank cover and the tank opening is more prone to sealing failure. Hydrogen is a colorless, odorless and highly flammable gas. Once it leaks from the joint between the tank cover and the tank opening, it is not only difficult to detect directly through the senses, but also very likely to cause a deflagration accident, posing a major safety hazard.

[0008] As a preferred technical solution of the present invention, a pressure plate is arranged inside the water storage tank, and the pressure plate and the water storage tank form a piston structure.

[0010] As a preferred technical solution of the present invention, an upper lifting frame is fixedly connected to the upper surface of the pressure plate.

[0011] As a preferred technical solution of the present invention, a water injection pipe is fixedly inserted into the transverse section of the upper lifting frame, the lower end of the water injection pipe passes through the pressure plate, and a cover is installed at the upper end of the water injection pipe.

[0012] As a preferred technical solution of the present invention, two groups of brackets are fixedly connected to the surface of the reactor, and the two groups of brackets are grouped in pairs.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, when gas leaks from the joint between the port and the cover, the airflow formed by the leaking gas will drive the fan blades to rotate. During the rotation of the fan blades, the two racks will move in opposite directions through the transmission mechanism of the first gear. This process causes the limiting block to smoothly escape from the limiting frame, thereby releasing the energy accumulated by the pressure spring, exerting pressure on the water in the water storage tank, and driving the water to be evenly sprayed in the form of mist in the surrounding area of ​​the reactor through the atomizing nozzle. In the event of hydrogen leakage, the risk of explosion accidents can be effectively reduced by timely spraying of water mist.

[0017] 2. Driven by the first gear, the two mobile racks of the present invention move along the two sides of the water tank until the rack separates from the first gear. At this time, the reset spring drives the rack to re-engage with the first gear. As the first gear continues to rotate, the rack disengages again. This process of engagement and disengagement repeats itself, causing the mobile rack to vibrate horizontally. This vibration triggers the bell to sound, alerting the surrounding operators to gas leakage in the form of acoustic signals, thereby prompting them to take timely countermeasures and effectively manage potential safety risks.

[0018] 3. The present invention can make the atomizing nozzle reciprocate along the preset support frame track during the rotation of the fan blades, which not only expands the coverage of the atomizing nozzle spraying water mist, but also significantly improves the diffusion rate and uniformity of the water mist. By optimizing the distribution of the water mist, the diffusion rate of the water mist is accelerated, the probability of explosion accidents is effectively reduced, and the overall safety performance is improved.

[0028] See also Figure 1-7 The present invention provides a technical solution of a methanol-to-hydrogen converter with high sealing performance:

[0029] The invention comprises a reactor 1, a port 2 and a port cover 3, wherein the port 2 is connected to the reactor 1, the port cover 3 is fixedly installed on the surface of the port 2, a water storage tank 401 is fixedly connected to the surface of the reactor 1, a water delivery pipe 406 is connected to the lower surface of the water storage tank 401, a water delivery hose 408 is connected to the lateral part of the water delivery pipe 406, a support frame 421 is fixedly connected to the surface of the water delivery pipe 406, a moving block 420 is slidably connected to the surface of the support frame 421, an atomizing nozzle 419 is fixedly installed on the surface of the moving block 420, the water delivery hose 408 is connected to the atomizing nozzle 419, the water in the water storage tank 401 is sprayed out through the atomizing nozzle 419 and sprayed around the reactor 1, so as to reduce the occurrence of explosion accidents when hydrogen leaks.

[0030] A sealing cover 403 is fixedly connected to the surface of the reactor 1, and an annular ring 402 is fixedly connected to the surface of the sealing cover 403. The top of the annular ring 402 is connected to an air outlet pipe 432, and the upper end of the air outlet pipe 432 is connected to an air outlet shell 422. Through the air outlet pipe 432, when the leaked gas passes through the air outlet shell 422, the leaked gas only flows through one side of the air outlet shell 422 to avoid the fan blade 426 from getting stuck when the fan blade 426 is driven to rotate. The interior of the air outlet shell 422 is rotatably connected to a first rotating shaft 425, and the surface of the first rotating shaft 425 is fixedly sleeved with fan blades 426. The airflow generated by the flow of the leaked gas will drive the fan blades 426 to rotate, so as to serve as a power source for a series of mechanisms, and no circuit is required during the startup and operation process, further reducing the risk of explosion accidents. The fan blades 426 are located inside the air outlet shell 422.

[0031] Among them, the surface of the moving block 420 is rotatably connected to the first rotating arm 428, one end of the first rotating shaft 425 is fixedly connected to the second rotating arm 430, the first rotating arm 428 and the second rotating arm 430 are fixedly connected through the second rotating shaft 429, the surface of the second rotating shaft 429 is fixedly sleeved with a second gear 424, an inner ring gear 427 is fixedly connected between the two short arm ends of the support frame 421, the second gear 424 is meshed with the inner ring gear 427, during the rotation of the fan blade 426, the cooperation of the first rotating arm 428 and the second rotating arm 430 can make the atomizing nozzle 419 swing, increase the diffusion range and diffusion speed of the water mist sprayed by the atomizing nozzle 419, and the inner wall of the outlet end of the air outlet pipe 432 is fixedly connected to a sealing film 431, and the sealing film 431 can prevent the airflow generated when the bin cover 3 is closed from causing the fan blade 426 to rotate and trigger the relevant mechanism.

[0032] The water storage tank 401 is provided with a pressure plate 416 inside, and the pressure plate 416 and the water storage tank 401 form a piston structure. The upper end of the water storage tank 401 is fixedly connected to a plurality of supporting cross plates 414, and the lower surfaces of the plurality of supporting cross plates 414 are fixedly connected to pressure springs 415, and the lower ends of the plurality of pressure springs 415 are fixedly connected to the upper surface of the pressure plate 416. The pressure springs 415 release pressure downward, and the water in the water storage tank 401 can be exerted through the pressure plate 416. The pressure is applied to make the atomizing nozzle 419 spray water mist. The upper surface of the pressure plate 416 is fixedly connected with an upper lifting frame 411, and the pressure plate 416 can be lifted by the upper lifting frame 411 to facilitate refilling of water into the water tank 401. A water injection pipe 412 is fixedly inserted into the transverse section of the upper lifting frame 411, and the water injection pipe 412 can be used to refill the water in the water tank 401 after the water is used up. The lower end of the water injection pipe 412 passes through the pressure plate 416, and a cover is installed at the upper end of the water injection pipe 412.

[0033] Among them, two groups of brackets 404 are fixedly connected to the surface of the reactor 1, and the two groups of brackets 404 are grouped in pairs. The surfaces of the two brackets 404 are slidably sleeved with a moving frame 407, and a limiting block 418 is welded to the upper end of the moving frame 407. Both ends of the pressure plate 416 are fixedly connected with a limiting frame 417 that is compatible with the limiting block 418. The limiting block 418 is inserted in the limiting frame 417 to limit the movement of the pressure plate 416. One end of the first rotating shaft 425 is fixedly connected with a first gear 423, and the lower ends of the two moving frames 407 are fixedly connected with racks 409. The two racks 409 are staggered up and down and are both engaged with the first gear 423.

[0034] Among them, a return spring 413 is fixedly connected to the surface of the mobile frame 407, and the return spring 413 can drive the rack 409 to re-engage with the first gear 423. One end of the return spring 413 is fixedly connected to the side of the water tank 401. One end of the two racks 409 is provided with a toothless section 410. The lower ends of the two mobile frames 407 are installed with bells 405. The lateral shaking of the mobile frame 407 can make the bell 405 make a sound, thereby reminding the surrounding operators of gas leakage so that they can respond and deal with it in time.

[0035] During specific use, if leakage occurs at the joint between the port 2 and the port cover 3, the leaked gas will enter the annular ring 402, and as the amount of leaked gas in the annular ring 402 increases, the pressure inside the annular ring 402 increases, which will rupture the sealing film 431, causing the leaked gas to pass through the outlet pipe 432 and enter the outlet shell 422 and be discharged. During this process, the airflow generated by the flow of the leaked gas will drive the fan blade 426 to rotate, and during the rotation of the fan blade 426, the first gear 423 will be driven to rotate, while the two racks 409 will move in opposite directions to each other, so that the limiting block 418 can be pulled out of the limiting frame 417, and the pressure spring 415 in a compressed state can be released downward, and pressure is applied to the water in the water tank 401 through the pressure plate 416, so that the water in the water tank 401 is sprayed out from the atomizing nozzle 419 through the water pipe 406 and the water hose 408 and sprayed around the reactor 1, thereby reducing the occurrence of explosion accidents when hydrogen leaks.

[0036] When the first gear 423 drives the limiting block 418 to disengage from the limiting frame 417, the two movable frames 407 move toward the two sides of the water tank 401 until the rack 409 disengages from the first gear 423, and then the rack 409 is driven by the reset spring 413 to re-engage with the first gear 423, and as the first gear 423 continues to rotate, the rack 409 disengages from the first gear 423 again. This reciprocating movement can cause the movable frame 407 to shake horizontally and make the bell 405 sound, thereby reminding the surrounding operators of gas leakage so that they can respond and deal with it in time.

[0037] During the rotation of the fan blade 426, the cooperation of the first rotating arm 428 and the second rotating arm 430 can make the second gear 424 rotate inside the inner ring 427, so that the atomizing nozzle 419 on the moving block 420 can move back and forth along the trajectory of the support frame 421, thereby realizing the swing of the atomizing nozzle 419, which can increase the diffusion range and diffusion speed of the water mist sprayed by the atomizing nozzle 419, improve the reaction speed, and further reduce the probability of explosion accidents.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
