Description

TECHNICAL FIELD

[0001] The application relates to the technical field of hydrogen production from methanol, and particularly relates to a heating device for hydrogen production from methanol. BACKGROUND

[0002] Hydrogen has a wide range of applications in industry, and the demand for pure hydrogen has rapidly increased in recent years. Common methanol cracking for hydrogen production is divided into two types: high-temperature cracking and low-temperature cracking. The low-temperature cracking has more side reactions and is difficult to control, and the content of other impurities in the product is relatively high. The high-temperature cracking has fewer side reactions and the product has high purity. At present, after methanol is cracked at high temperature in the cracking device, a large amount of carbon monoxide and uncracked methanol are produced. If the carbon monoxide and methanol are directly discharged, they will cause great pollution to the environment and harm to the human body, thereby resulting in low environmental protection effect.

[0003] To solve the above problems, a cracking device for treating uncracked methanol and carbon monoxide produced after high-temperature cracking has appeared on the market. The cracking device comprises a cracking box, a purification box and a cracking mechanism arranged in the cracking box. The purification box is communicated with the cracking box. When the device is used, the methanol aqueous solution is first cracked at high temperature by the cracking mechanism to produce hydrogen. After the hydrogen is produced, the carbon monoxide and uncracked methanol flow into the purification box together with the hydrogen. The purification box stores an ethanol aqueous solution, which can absorb the carbon monoxide and methanol, thereby ensuring that only hydrogen is discharged from the purification box and collected, reducing the pollution of methanol and carbon monoxide to the environment and harm to the human body, and improving the practicality of the device.

[0004] The above device has the following problems in actual use: the hydrogen, carbon monoxide and methanol cracked at high temperature have a high flow rate under the action of high temperature, and the ethanol aqueous solution in the purification box can only passively absorb the methanol and carbon monoxide. The absorption process is short, and the residence time of the methanol and carbon monoxide in the purification box cannot be prolonged, so that the methanol and carbon monoxide cannot be fully mixed with the ethanol aqueous solution, thereby causing the methanol and carbon monoxide to be insufficiently treated, and causing the methanol and carbon monoxide to be discharged from the gas outlet in the purification box, that is, the treatment of the methanol and carbon monoxide is incomplete and not thorough, and the green environmental protection requirement cannot be met. SUMMARY

[0005] The application provides a heating device for hydrogen production from methanol, to solve the problem that the existing hydrogen production device is insufficient and incomplete in treating the tail gas discharged from the purification box.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a heating device for methanol-to-hydrogen production, comprising a cracking chamber with an inlet and an outlet, a cracking mechanism disposed within the cracking chamber, and a processing chamber with a bottom hole and a top hole, and a processing mechanism disposed within the processing chamber; the processing chamber is fixedly connected to the cracking chamber, and the bottom hole and the outlet are connected; the processing mechanism comprises a plurality of processing components equidistantly arranged along the height direction of the processing chamber; the processing components comprise a storage chamber, a processing section disposed on the storage chamber, and a driving section for driving the storage chamber to reciprocate along the length direction of the processing chamber; the storage chamber and the processing chamber are slidably connected, and adjacent storage chambers are staggered, with the movement directions of adjacent storage chambers being opposite; the processing section comprises an atomizing unit disposed within the storage chamber and an outlet unit symmetrically disposed on both sides of the storage chamber along the length direction of the storage chamber; the outlet unit comprises a conduit and a plurality of guide holes opened on the conduit; the conduit is connected to the storage chamber.

[0007] The principles and advantages of this scheme are:

[0008] 1. A methanol-water solution is passed into a pyrolysis chamber for high-temperature pyrolysis, which produces hydrogen gas under the high temperature of the pyrolysis mechanism. After hydrogen production, the hydrogen, carbon monoxide from the high-temperature pyrolysis, and unpyrolyzed methanol are discharged into a treatment chamber. During the flow of methanol and carbon monoxide within the treatment chamber, an ethanol-water spray is emitted through conduits. This ethanol-water spray purifies the carbon monoxide and methanol, reducing their environmental pollution and harm to humans. Simultaneously, the ethanol-water spray reduces the flow rate of methanol and carbon monoxide, extending their contact time. Furthermore, because several conduits are equidistantly spaced along the height of the treatment chamber, the ethanol-water spray is more evenly and completely distributed, ensuring more thorough contact with methanol and carbon monoxide, thus enhancing the purification effect and efficiency of the ethanol-water spray.

[0009] 2. During the spraying of ethanol-water from the conduit, the conduit can reciprocate along the length of the treatment chamber, thereby expanding the discharge range of the ethanol-water spray. This further ensures that the ethanol-water spray can be distributed more evenly and completely within the treatment chamber, improving the utilization rate of the ethanol-water spray. In other words, the ethanol-water spray has a better purification quality for methanol and carbon monoxide.

[0010] 3. Because the two adjacent storage tanks move in opposite directions and there is a certain distance between the inner walls of the storage tank and the processing tank, a Z-shaped path is formed between the two adjacent storage tanks and the processing tank. Methanol and carbon monoxide move along the Z-shaped path in the processing tank, which greatly increases the distance that methanol and carbon monoxide travel in the processing tank, thereby prolonging the time that methanol and carbon monoxide travel in the processing tank, and further ensuring that methanol and carbon monoxide can be completely purified under the action of ethanol-water spray.

[0011] Furthermore, the processing unit also includes linkage units symmetrically arranged on both sides of the storage tank along the length direction of the storage tank; the linkage unit includes a piston cylinder, a piston block, and a drive unit for driving the piston block to reciprocate along the length direction of the piston cylinder; the piston cylinder is fixedly connected to the inner wall of the storage tank; the piston block is slidably connected to the piston cylinder; an air inlet pipe and an air outlet pipe are respectively connected to the piston cylinder; the free end of the air outlet pipe is connected to the conduit.

[0012] Through the cooperation of the piston block and piston cylinder, the piston cylinder can draw the ethanol-water spray from the storage tank into the conduit and pressurize the ethanol-water spray flowing in the conduit. As a result, when the ethanol-water spray is ejected from the guide hole, the force of the ejected ethanol-water spray is increased, and the flow rate of the ethanol-water spray is accelerated. This allows the ethanol-water spray to travel a longer distance and have a wider range of action, thus comprehensively enhancing the purification effect of ethanol-water spray on methanol and carbon monoxide.

[0013] Furthermore, the linkage unit also includes a linkage component; the linkage component includes a linkage block and a mesh plate; the linkage block is located inside the guide tube, the linkage block is slidably connected to the piston cylinder, one end of the linkage block is fixedly connected to the piston block, and the other end of the linkage block is fixedly connected to the mesh plate; the mesh plate is attached to the inner wall of the guide tube, and the guide hole is located on the movement trajectory of the mesh plate.

[0014] During the ejection of ethanol-water spray from the guide hole, the mesh plate reciprocates along the length of the conduit. The mesh plate can reduce the aperture of the ethanol-water spray ejected from the guide hole, thereby increasing the pressure inside the conduit. This makes the ethanol-water spray have a stronger force and a wider range of action when it is ejected from the guide hole, which further improves the utilization rate of the ethanol-water spray and enhances its effect.

[0015] Furthermore, it also includes an auxiliary part set in the two conduits; the auxiliary part includes a guide block, an auxiliary block, a blocking block symmetrically set at both ends of the auxiliary block, and a power unit for driving the auxiliary block to make vertical reciprocating motion; the guide block is fixedly connected to the outer wall of the storage box; the auxiliary block is slidably connected to the guide block; the blocking block is fixedly connected to the auxiliary block, the blocking block is slidably connected to the conduit, and the end of the blocking block away from the auxiliary block extends into the conduit.

[0016] The vertical reciprocating motion of the sealing block continuously alters the diameter of the ethanol-water spray flow within the conduit, thereby regulating the pressure of the ethanol-water spray within the conduit. This motion further increases the force exerted when the ethanol-water spray is discharged, resulting in a longer flow distance and a wider diffusion range. This allows the ethanol-water spray to mix more thoroughly and completely with methanol and carbon monoxide, thus improving the purification efficiency of the ethanol-water spray.

[0017] Furthermore, it also includes a diffusion section disposed between the two conduits; the diffusion section includes a diffusion tube, a plurality of diffusion units equidistantly arranged along the circumferential direction of the diffusion tube, and a motion unit for driving the diffusion tube to rotate; the diffusion tube is rotatably connected to the conduit and communicates with the conduit; the diffusion unit includes a diffusion block, a chamber opened in the diffusion block, and a plurality of diffusion holes opened on the chamber; the diffusion block is fixedly connected to the diffusion tube; the chamber communicates with the diffusion tube.

[0018] During its flow within the conduit, the ethanol-water spray exits through the diffuser orifice, thus increasing the discharge methods and promoting more comprehensive distribution of the ethanol-water spray within the treatment chamber. Furthermore, the rotating diffuser block exerts centrifugal force, expanding the effective range of the ethanol-water spray as it exits the diffuser orifice. This allows the ethanol-water spray to exit circumferentially, further ensuring its comprehensive flow within the treatment chamber and enhancing its effectiveness against methanol and carbon monoxide.

[0019] During the rotation of the diffuser block, the diffuser block can stir and mix the ethanol water spray, methanol, and carbon monoxide flowing in the treatment tank, thereby enhancing the treatment effect of the ethanol water spray on methanol and carbon monoxide, that is, accelerating the treatment progress of the ethanol water spray on methanol and carbon monoxide, and improving the purification efficiency of the ethanol water spray.

[0020] Furthermore, the diffusion section also includes an auxiliary unit within the conduit; the auxiliary unit includes an elastic suction tube and a squeezing block; the elastic suction tube is connected to the diffusion tube; the squeezing block is fixed to the mesh plate, and the elastic suction tube is located on the movement trajectory of the squeezing block.

[0021] The flexible straw is designed to increase the diameter of the ethanol-water spray entering the diffuser tube, thereby allowing a sufficient amount of ethanol-water spray to flow into the diffuser tube along the flexible straw. This ensures that a large amount of ethanol-water spray is flowing within the diffuser tube, allowing the ethanol-water spray to be fully and completely discharged from the diffuser hole.

[0022] As the ethanol-water spray flows into the diffuser along the elastic straw, the mesh plate drives the extrusion block to continuously compress the elastic straw, causing it to deform. During this deformation, the pressure of the ethanol-water spray flowing into the diffuser increases, resulting in a faster flow rate and a longer travel distance for the ethanol-water spray as it exits the diffuser.

[0023] Furthermore, brush layers are fixed to both sides of the diffuser block; the guide holes are located on the movement trajectory of the brush layers.

[0024] During the movement of the bristle layer, it exerts a certain force, effectively clearing impurities clogged within the guide holes and preventing blockage. Through this movement, the ethanol-water spray flows efficiently within the guide holes, thereby improving its flow efficiency and enhancing its effectiveness. This further ensures that the ethanol-water spray can adequately treat methanol and carbon monoxide.

[0025] Furthermore, the diffuser also includes a blower unit; the blower unit includes a blower shaft, a number of fan blades equidistantly arranged along the circumferential direction of the blower shaft, and a drive component for driving the blower shaft to rotate; the blower shaft is rotatably connected to the storage tank; the fan blades are fixedly connected to the blower shaft.

[0026] During the rotation of the fan blades, the fan blades can further accelerate the flow speed of the ethanol water spray, enabling the ethanol water spray to flow a longer distance and spread a wider range within the treatment chamber, thereby enhancing the mixing effect of the ethanol water spray with methanol and carbon monoxide.

[0027] Furthermore, it also includes moving parts mounted on the storage box; the moving parts include a rotating shaft, a gear, and a rack; the rotating shaft is rotatably connected to the storage box; the gear is fixedly connected to the rotating shaft; the rack is fixedly connected to the inner wall of the processing box, and the gear meshes with the rack; the drive unit includes a first cam and a first spring; the first cam is fixedly connected to the rotating shaft and abuts against the piston block; the two ends of the first spring are respectively connected to the piston cylinder and the piston block.

[0028] During the reciprocating motion of the storage tank along the length of the processing tank, the rotating shaft moves synchronously. During this motion, the shaft rotates through the meshing of gears and racks. Therefore, while the shaft reciprocates along the length of the processing tank, it can also rotate.

[0029] During the rotation of the shaft, the first cam rotates synchronously. During the rotation of the first cam, when the protrusion of the first cam abuts against the piston block, the piston block moves away from the shaft, and the first spring is compressed; when the protrusion of the first cam no longer abuts against the piston block, the piston block returns to its original position under the action of the first spring, and moves closer to the shaft. Therefore, the piston block can reciprocate along the length of the piston cylinder.

[0030] Furthermore, the power unit includes a second cam and a second spring; the second cam is fixedly connected to the blower shaft and abuts against the auxiliary block; the two ends of the second spring are respectively connected to the guide block and the auxiliary block.

[0031] During the rotation of the blower shaft, the second cam rotates synchronously. When the protrusion of the second cam abuts against the auxiliary block, the auxiliary block moves vertically upward, compressing the second spring; when the protrusion of the second cam no longer abuts against the auxiliary block, the auxiliary block returns to its original position under the action of the second spring, moving vertically downward. Therefore, the auxiliary block can perform vertical reciprocating motion. Attached Figure Description

[0055] The driving component is a worm gear 37; the worm gear 37 is fixedly connected to the blower shaft 27; the rotating shaft 29 is a worm; the worm meshes with the worm gear 37.

[0056] Specific implementation process:

[0057] A methanol-water solution is introduced into the pyrolysis chamber 1, where it is first vaporized by the vaporizing rod 3. The vaporized methanol-water then flows into the pyrolysis block 2 for high-temperature pyrolysis, thus producing hydrogen gas. After hydrogen production, the hydrogen, carbon monoxide from the high-temperature pyrolysis, and unpyrolyzed methanol are discharged into the processing chamber 4. While the methanol and carbon monoxide are flowing into the processing chamber 4, the booster pump 10 is activated, causing the ethanol-water solution in the storage chamber to flow into the operating chamber and be converted into an ethanol-water spray by the atomizing tube 9. The ethanol-water spray eventually flows into the conduit 6 and is ejected from the guide hole 7.

[0058] During the spraying of ethanol-water mist from guide hole 7, the ethanol-water mist can purify carbon monoxide and methanol, thereby reducing the pollution of methanol and carbon monoxide to the environment and minimizing their harm to the human body. Simultaneously, the spraying of ethanol-water mist reduces the flow rate of methanol and carbon monoxide, prolonging the contact time between the ethanol-water mist and methanol and carbon monoxide. Furthermore, because several guide tubes 6 are equidistantly arranged along the height of the treatment chamber 4, the ethanol-water mist can be sprayed more evenly and completely within the treatment chamber 4, allowing for more thorough contact between the ethanol-water mist and methanol and carbon monoxide, thus enhancing the purification effect of the ethanol-water mist on methanol and carbon monoxide and improving the purification efficiency of the ethanol-water mist.

[0059] During the ethanol-water spraying process from conduit 6, cylinder 12 is activated. The output shaft of cylinder 12 drives storage tank 5 to reciprocate along the length of treatment tank 4, with conduit 6 moving synchronously. This reciprocating motion of conduit 6 along the length of treatment tank 4 expands the discharge range of the ethanol-water spray, ensuring a more uniform and complete distribution within treatment tank 4. This improves the utilization rate of the ethanol-water spray, resulting in better purification of methanol and carbon monoxide.

[0060] Since the two adjacent storage tanks 5 move in opposite directions and there is a certain distance between the inner walls of the storage tanks 5 and the processing tank 4, a Z-shaped path is formed between the two adjacent storage tanks 5 and the processing tank 4. Methanol and carbon monoxide move along the Z-shaped path in the processing tank 4, which greatly increases the distance that methanol and carbon monoxide travel in the processing tank 4, thereby prolonging the time that methanol and carbon monoxide travel in the processing tank 4, and further ensuring that methanol and carbon monoxide can be completely purified under the action of ethanol-water spray.

[0061] During the reciprocating motion of the storage tank 5 along the length of the processing tank 4, the worm gear moves synchronously. During the worm gear's movement, it rotates through the meshing of the gear 30 and the rack 31. Therefore, while the worm gear reciprocates along the length of the processing tank 4, it can also rotate.

[0062] During the rotation of the worm gear, the first cam 32 rotates synchronously. During the rotation of the first cam 32, when the protrusion of the first cam 32 abuts against the piston block 14, the piston block 14 moves away from the worm gear, and the first spring 33 is compressed; when the protrusion of the first cam 32 no longer abuts against the piston block 14, the piston block 14 returns to its original position under the action of the first spring 33, and moves closer to the worm gear. Therefore, the piston block 14 can reciprocate along the length of the piston cylinder 13.

[0063] Through the cooperation of piston block 14 and piston cylinder 13, piston cylinder 13 can draw ethanol water spray from storage tank 5 into conduit 6 and pressurize the ethanol water spray flowing in conduit 6. As a result, when the ethanol water spray is ejected from guide hole 7, the force of the ethanol water spray when ejected is increased and the flow rate of the ethanol water spray is accelerated. This allows the ethanol water spray to travel a longer distance and have a wider range of action, thus comprehensively enhancing the purification effect of ethanol water spray on methanol and carbon monoxide.

[0064] During the movement of piston block 14, linkage block 16 moves synchronously. During the movement of linkage block 16, mesh plate 17 moves synchronously. During the movement of mesh plate 17, mesh plate 17 can reduce the orifice diameter of the ethanol water spray ejected from guide hole 7, thereby increasing the pressure inside conduit 6. This causes the ethanol water spray to have a stronger force and a wider range of action when it is ejected from guide hole 7, thus further improving the utilization rate of ethanol water spray and enhancing its effect.

[0065] During the rotation of the worm gear, the worm wheel 37 meshes with the worm gear, thereby driving the blower shaft 27 to rotate. During the rotation of the blower shaft 27, the second cam 34 rotates synchronously. During the rotation of the second cam 34, when the protrusion of the second cam 34 abuts against the auxiliary block 19, the auxiliary block 19 moves vertically upward, and the second spring is compressed; when the protrusion of the second cam 34 no longer abuts against the auxiliary block 19, the auxiliary block 19 returns to its original position under the action of the second spring, and the auxiliary block 19 moves vertically downward. Therefore, the auxiliary block 19 can perform vertical reciprocating motion. During the movement of the auxiliary block 19, the sealing block 20 moves synchronously.

[0066] The vertical reciprocating motion of the blocking block 20 continuously alters the diameter of the ethanol-water spray flow within the conduit 6, thereby regulating the pressure of the ethanol-water spray within the conduit 6. This motion further increases the force exerted when the ethanol-water spray is discharged, resulting in a longer flow distance and a wider diffusion range. This allows the ethanol-water spray to mix more thoroughly and completely with methanol and carbon monoxide, thus improving the purification efficiency of the ethanol-water spray.

[0067] During the flow of the ethanol-water spray within the conduit 6, it exits through the diffuser hole 23, thereby increasing the discharge methods and promoting a more comprehensive distribution of the ethanol-water spray within the treatment chamber 4. Furthermore, since the diffuser block 22 can rotate, it possesses a certain centrifugal force, which expands the effective range of the ethanol-water spray as it exits through the diffuser hole 23, allowing the ethanol-water spray to exit circumferentially. This further ensures that the ethanol-water spray flows comprehensively within the treatment chamber 4, enhancing its effectiveness against methanol and carbon monoxide.

[0068] During the rotation of the worm gear, the connecting shaft 35 is driven by the belt 36 to rotate the diffuser tube 21. The diffuser block 22 rotates synchronously during its rotation. During this rotation, the diffuser block 22 stirs and mixes the ethanol-water spray, methanol, and carbon monoxide flowing in the treatment tank 4, thereby enhancing the treatment effect of the ethanol-water spray on methanol and carbon monoxide, accelerating the treatment process, and improving the purification efficiency of the ethanol-water spray.

[0069] The flexible straw 24 is designed to increase the diameter of the ethanol water spray entering the diffuser tube 21, thereby allowing a sufficient amount of ethanol water spray to flow into the diffuser tube 21 along the flexible straw 24. This ensures that a large amount of ethanol water spray is flowing in the diffuser tube 21, so that the ethanol water spray can be fully and completely discharged from the diffuser hole 23.

[0070] As the ethanol-water spray flows along the elastic straw 24 into the diffuser 21, the mesh plate 17 drives the extrusion block 25 to continuously compress the elastic straw 24, causing it to deform. During the deformation of the elastic straw 24, the pressure of the ethanol-water spray flowing into the diffuser 21 increases, which in turn increases the flow rate of the ethanol-water spray when it exits from the diffuser hole 23, allowing it to travel a greater distance.

[0071] During the rotation of the diffuser block 22, the bristle layer 26 moves synchronously. During this movement, the bristle layer 26 exerts a certain force, effectively cleaning impurities clogged within the guide hole 7 and preventing blockage. Through this movement, the ethanol-water spray can flow efficiently within the guide hole 7, thereby improving its flow efficiency and enhancing its effectiveness. This further ensures that the ethanol-water spray can adequately treat methanol and carbon monoxide.

[0072] During the rotation of the blower shaft 27, the fan blades 28 rotate synchronously. During the rotation of the fan blades 28, the fan blades 28 can further accelerate the flow speed of the ethanol water spray, enabling the ethanol water spray to flow a longer distance and diffuse a wider range within the treatment chamber 4, thereby enhancing the mixing effect of the ethanol water spray with methanol and carbon monoxide.

[0073] In summary, by pressurizing the ethanol-water spray, expanding its effective range, reducing the flow rate of methanol and carbon monoxide, and increasing the travel distance of methanol and carbon monoxide, the ethanol-water spray is able to remove methanol and carbon monoxide, ensuring that the gas discharged from the treatment chamber 4 is environmentally friendly and harmless to humans.
