Description

Technical Field

[0001] This invention relates to the field of gas-liquid separation technology, specifically to a gas-liquid separation device for hydrogen production from natural gas. Background Technology

[0002] Natural gas steam reforming for hydrogen production is a process in which natural gas, after compression and desulfurization, is mixed with steam at a certain pressure in a reformer to produce hydrogen through a catalytic reaction. After compression and desulfurization, the natural gas and steam are mixed and, under the action of a nickel catalyst, the natural gas is converted into hydrogen (H2), carbon monoxide (CO), and carbon dioxide (CO2) into reformate gas at 750-850°C. The reformate gas can be converted from carbon monoxide (CO) to hydrogen (H2) through a conversion process, becoming a shifted gas. Before entering the pressure swing adsorption (PSA) purification unit, the shifted gas must be thoroughly dehydrated.

[0003] For example, a gas-liquid separator for hydrogen production, disclosed in CN119158367A, includes a separation platform with a separation chamber fixedly connected to it. A demister is fixedly connected to the upper outer surface of the separation chamber, and a separation filter is slidably connected to the upper inner wall of the separation chamber. By adjusting the outlet angle of the liquid outlet pipe, the flow state of the liquid entering the centrifugal separator can be optimized, reducing the impact and disturbance of the liquid on the gas. Moreover, under different operating conditions, the composition and flow rate of the mixture may vary, and the adjustable inlet angle allows users to adjust it according to actual needs to adapt to different operating conditions and ensure separation effect. Compared with the prior art, this design enhances the flexibility of the centrifugal separator, enabling it to play a role in a wider range of applications and improving the versatility and adaptability of the equipment.

[0004] For liquid droplets in hydrogen, a cyclone separator can be used, which uses centrifugal force to throw the droplets against the cylinder wall and discharge them. The liquid is discharged from the bottom drain pipe, while the hydrogen is discharged and collected from the top exhaust pipe. In order to improve the effect of gas-liquid centrifugal separation, a stainless steel wire mesh can be installed inside. However, for the atomized water droplets contained in hydrogen, due to their extremely small size, a water film can easily form on the surface of the wire mesh filter holes or block the filter holes. The filter holes in the inner ring of the wire mesh are less likely to be blocked due to the impact of rising hydrogen, while the filter holes in the outer ring are more likely to be blocked. This results in increased resistance when hydrogen passes through the filter holes in the outer ring of the wire mesh, which affects the upward flow of hydrogen and the effect of gas-liquid separation. Summary of the Invention

[0005] The purpose of this invention is to provide a gas-liquid separation device for hydrogen production from natural gas, in order to solve the problem that atomized water droplets, due to their extremely small size, easily form a water film on the surface of the wire mesh filter or clog the filter holes, resulting in increased resistance when hydrogen passes through the filter holes of the outer ring of the wire mesh, thus affecting the upward flow of hydrogen and the gas-liquid separation effect.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a gas-liquid separation device for hydrogen production from natural gas, comprising a base plate and a support column fixedly installed at the bottom of the base plate, wherein a processing box is fixedly connected to the top of the base plate; Also includes: An air inlet pipe is fixedly connected to one side of the bottom of the processing box, an exhaust pipe is fixedly installed on the top of the processing box, a separation component is provided inside the processing box, and a condensation component is provided on the outside of the air inlet pipe. The separation assembly includes a vertical cylinder and a filter cylinder fixedly installed on the top surface of the processing box. A servo motor is fixedly installed on the bottom of the base plate. A rotating rod is fixedly connected to the output end of the servo motor. A lower reciprocating lead screw and an upper reciprocating lead screw are fixedly connected to the top of the rotating rod in sequence.

[0007] Preferably, the rotating rod is rotatably connected to the processing box, the outer side of the lower reciprocating screw is threaded to a lower sleeve, the outer side of the lower sleeve is fixedly connected to a connecting rod, the end of the connecting rod away from the lower sleeve is fixedly connected to a slider, the slider is slidably connected to the spiral water channel, the lower interior of the filter cylinder is fixedly installed with a spiral water channel, the upper interior of the filter cylinder is fixedly installed with an inclined ring channel, the interior of the filter cylinder is also fixedly installed with a wire mesh part, the wire mesh part is located above the inclined ring channel, the interior of the inclined ring channel is slidably installed with a fixed frame, one end of the fixed frame is rotatably installed with an inclined plate, the inclined plate is in contact with the bottom surface of the wire mesh part.

[0008] By adopting the above technical solution, while centrifugation is being carried out, the inclined plate is attached to the bottom of the wire mesh and rotates. On the one hand, the inclined plate scrapes off the droplets attached to the wire mesh, and on the other hand, the inclined plate also assists in driving the internal puncturing roller to rotate while rotating. The puncturing roller punctures the water film remaining in the filter holes of the outer ring.

[0009] Preferably, a fixing rod is fixedly connected to one side of the bottom of the spiral waterway, the bottom end of the fixing rod is fixedly connected to the inner bottom surface of the treatment box, an upper rod body is fixedly connected to the inner top surface of the treatment box, the inclined ring channel is fixedly connected to the upper rod body, the wire mesh part is fixedly installed on the outer side of the upper rod body, and a spacer tooth block is fixedly connected to the top surface of the inner wall of the inclined ring channel.

[0010] By adopting the above technical solution, the upper pole is used to fix and install the upper pole and the wire mesh section.

[0011] Preferably, the outer side of the upper reciprocating screw is threaded with an upper sleeve, the outer side of the upper sleeve is fixedly connected with a connecting strip, the end of the connecting strip away from the upper sleeve is fixedly connected to a fixed frame, the bottom of the fixed frame is fixedly connected with a bottom block, and the bottom block is slidably connected to the inclined ring track.

[0012] By adopting the above technical solution, when the fixed frame slides inside the inclined ring, it will drive the bottom block to move synchronously.

[0013] Preferably, a fixing plate is fixedly connected inside the fixing frame, and a rotating shaft is rotatably connected inside the fixing plate. A gear is fixedly connected to one end of the rotating shaft, and the gear meshes with a spacer tooth block. A torsion spring is sleeved on the outside of the rotating shaft. One end of the torsion spring is fixedly connected to the spiral water channel, and the other end of the torsion spring is fixedly connected to the gear.

[0014] By adopting the above technical solution, when the gear meshes with the spacer block, it will drive the rotating shaft to rotate. The rotating shaft acts on the torsion spring one, and the rotating shaft drives the puncturing roller to rotate through the universal coupling. When the gear separates from the spacer block, the torsion spring one drives the rotating shaft to rotate back to reset, so that the puncturing roller rotates back.

[0015] Preferably, a side shaft is rotatably connected between the fixed frame and the inclined plate, a second torsion spring is sleeved on the outside of the side shaft, one end of the second torsion spring is fixedly connected to the fixed frame, the other end of the second torsion spring is fixedly connected to the inclined plate, a puncturing roller is rotatably connected inside the inclined plate, and a universal coupling is fixedly installed between the rotating shaft and the puncturing roller.

[0016] By adopting the above technical solution, the torque of the second torsion spring presses the inclined plate tightly against the bottom surface of the wire mesh section, making it easier to scrape off the bottom outer ring of the wire mesh section.

[0017] Preferably, the condensation assembly includes a fixing sleeve that is fitted and fixed to the outside of the air inlet pipe, a water inlet pipe that is fixedly connected to the top of the fixing sleeve, a water outlet pipe that is fixedly connected to the bottom of the fixing sleeve, a solenoid that is fitted to the outside of the air inlet pipe, and an annular cover that is fixedly connected to both sides of the solenoid.

[0018] By adopting the above technical solution, cooling water flows into the annular cover on one side through the inlet pipe, then into the solenoid and the annular cover on the other side, and finally flows out from the outlet pipe into the return pipe, which facilitates the pre-condensation of the mixed gas.

[0019] Preferably, the annular cover is rotatably connected to the air inlet pipe, one side of the annular cover is connected to the water inlet pipe, and an axial flow fan blade is rotatably connected to the inner side of the annular cover on that side. The axial flow fan blade is located inside the air inlet pipe, and the other side of the annular cover is connected to the water outlet pipe.

[0020] By adopting the above technical solution, the gas flow drives the axial fan blades to rotate, and the axial fan blades drive the annular cover on one side to rotate, which at the same time causes the annular cover on the other side of the solenoid to rotate as well, which not only prolongs the contact condensation time, but also expands the contact area.

[0021] Preferably, a drain pipe is fixedly connected to one side of the bottom of the treatment box, a collection box is fixedly connected to the bottom end of the drain pipe, a filter plate is fixedly installed inside the collection box, a discharge pipe is fixedly installed on the outside of the collection box, and a shut-off valve is fixedly installed on the outside of both the drain pipe and the discharge pipe.

[0022] By adopting the above technical solution, the separated water flows into the collection tank through the drain pipe. The collection tank is equipped with a filter plate for filtration. The water can be discharged by opening the shut-off valve on the outside of the discharge pipe.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting up a separation component, and utilizing the cooperation of components such as the wire mesh section and the inclined plate, during centrifugal separation, the lower sleeve and the upper sleeve will move away from each other. The upper sleeve will drive the inclined plate to move. Through the guidance of the arc-shaped limiting strip and the force of the torsion spring, the inclined plate will be kept in contact with the bottom of the wire mesh section and will circle around. On the one hand, the inclined plate scrapes off the droplets attached to the wire mesh section. On the other hand, when the inclined plate circles, it will also assist in driving the internal piercing roller to rotate. The piercing roller rotates autonomously, causing the piercing roller to pierce the water film remaining in the filter holes of the outer ring. The puncture treatment is suitable for treating water film blockage in the inclined wire mesh section, reducing resistance to subsequent hydrogen flow. It involves segmenting and sequentially puncturing the water film on the outer ring of the wire mesh, maintaining a continuous and good treatment effect without significantly hindering the rising hydrogen. The lower sleeve drives the slider to move in the spiral channel, facilitating the downward spiral discharge of some scraped water and guiding the airflow to generate a downward axial velocity component. This reduces short-circuit flow and secondary entrainment of hydrogen on the bottom water, facilitating rapid separation of water and hydrogen and improving the efficiency of centrifugal separation. Details are as follows: 1. By setting up a separation component, the operator inputs the external mixed gas into the inlet pipe, and the exhaust pipe is connected to an external induced draft fan. The mixed gas enters the processing box, and at the same time, the servo motor is started to rotate. The servo motor drives the rotating rod, the lower reciprocating screw, and the upper reciprocating screw to rotate. Due to the spiral channel limiting the slider, the rotation of the lower reciprocating screw will cause the lower sleeve and the connecting rod to move up and down. The connecting rod drives the slider to move back and forth. When the slider descends, it will rotate to match the inclination of the spiral channel. The mixed gas is drawn into the filter cartridge, and the droplets are thrown onto the filter cartridge and the vertical cylinder. The hydrogen spirals upward and is discharged through the exhaust pipe. Similarly, the inclined ring channel limits the fixed frame. The rotation of the upper reciprocating screw will drive the upper sleeve, the connecting bar, and the fixed frame to move up and down. The fixed frame drives the inclined plate to move in a tilting circle. The torque of the torsion spring two presses the inclined plate tightly against the bottom surface of the wire mesh part. This design facilitates scraping and cleaning of the bottom outer ring of the mesh section. When the gear meshes with the spacer, it drives the rotating shaft to rotate. The rotating shaft acts on the torsion spring and drives the piercing roller to rotate through the universal coupling. When the gear separates from the spacer, the torsion spring drives the rotating shaft to rotate back to its original position, causing the piercing roller to rotate. This achieves segmented and sequential piercing of the water film remaining in the outer ring filter holes, reducing the resistance of the water film to the subsequent hydrogen flow. It can maintain a continuous and good treatment effect without significantly hindering the rising hydrogen. The lower sleeve will drive the slider to move in the spiral channel, which facilitates the downward spiral discharge of some of the scraped water and guides the airflow to generate a downward axial velocity component. This reduces the short-circuit flow and the secondary entrainment of hydrogen on the bottom water, facilitating the rapid separation of water and hydrogen and improving the efficiency of centrifugal separation. 2. By setting up a condensation assembly, the operator connects the external cooling water to the inlet pipe and the outlet pipe to the external return pipe. The cooling water flows into the annular shroud on one side through the inlet pipe, then into the solenoid and the annular shroud on the other side, and finally flows out into the return pipe from the outlet pipe. After the mixed gas enters the intake pipe, the gas flow drives the axial fan blades to rotate, which in turn drives the annular shroud on one side to rotate. At the same time, the annular shroud on the other side of the solenoid also rotates. This prolongs the contact condensation time and expands the contact area, facilitating the pre-condensation of the mixed gas and the subsequent gas-liquid separation operation.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1 - Figure 2The present invention provides a technical solution: a gas-liquid separation device for hydrogen production from natural gas, including a base plate 1 and support columns 2 fixedly installed at the bottom of the base plate 1. A processing box 3 is fixedly connected to the top of the base plate 1, and there are no fewer than four support columns 2 to facilitate stable support.

[0028] An air inlet pipe 4 is fixedly connected to one side of the bottom of the treatment box 3, and an exhaust pipe 5 is fixedly installed on the top of the treatment box 3.

[0029] like Figure 1 and Figure 3 - Figure 10 As shown, the processing box 3 is equipped with a separation component 6. The separation component 6 includes a vertical cylinder 61 and a filter cylinder 62 fixedly installed on the top surface of the processing box 3. A servo motor 63 is fixedly installed at the bottom of the base plate 1. A rotating rod 64 is fixedly connected to the output end of the servo motor 63. A lower reciprocating lead screw 65 and an upper reciprocating lead screw 614 are fixedly connected to the top of the rotating rod 64 in sequence.

[0030] Rotating rod 64 is rotatably connected to treatment box 3. Lower reciprocating screw 65 is threaded to the outer side of lower sleeve 66. Connecting rod 67 is fixedly connected to the outer side of lower sleeve 66. Slider 68 is fixedly connected to the end of connecting rod 67 away from lower sleeve 66. Slider 68 is slidably connected to spiral channel 610. Spiral channel 610 is fixedly installed inside the lower part of filter cylinder 62. Slider 68 slides inside spiral channel 610 to facilitate the downward spiraling push of water remaining in spiral channel 610.

[0031] An inclined ring channel 612 is fixedly installed inside the upper part of the filter cylinder 62. A wire mesh part 11 is also fixedly installed inside the filter cylinder 62. The wire mesh part 11 is located above the inclined ring channel 612. A fixed frame 617 is slidably installed inside the inclined ring channel 612. An inclined plate 624 is rotatably installed at one end of the fixed frame 617. The inclined plate 624 is in contact with the bottom surface of the wire mesh part 11. The cooperation of the side shaft 623 and the second torsion spring 625 makes it easy to keep the inclined plate 624 in contact with the bottom surface of the wire mesh part 11.

[0032] A fixing rod 69 is fixedly connected to one side of the bottom of the spiral waterway 610. The bottom end of the fixing rod 69 is fixedly connected to the inner bottom surface of the treatment box 3. An upper rod body 611 is fixedly connected to the inner top surface of the treatment box 3. An inclined ring channel 612 is fixedly connected to the upper rod body 611. A wire mesh part 11 is fixedly installed on the outer side of the upper rod body 611. A spacer tooth block 613 is fixedly connected to the top surface of the inner wall of the inclined ring channel 612 to facilitate the reciprocating rotation of the subsequent gear 621 and the rotating shaft 620.

[0033] The upper reciprocating screw 614 is threaded to the outer side of an upper sleeve 615. A connecting strip 616 is fixedly connected to the outer side of the upper sleeve 615. The end of the connecting strip 616 away from the upper sleeve 615 is fixedly connected to a fixed frame 617. A bottom block 618 is fixedly connected to the bottom of the fixed frame 617. The bottom block 618 is slidably connected to the inclined ring track 612.

[0034] A fixing plate 619 is fixedly connected inside the fixing frame 617. A rotating shaft 620 is rotatably connected inside the fixing plate 619. A gear 621 is fixedly connected to one end of the rotating shaft 620. The gear 621 meshes with the spacer block 613. A torsion spring 622 is sleeved on the outside of the rotating shaft 620. One end of the torsion spring 622 is fixedly connected to the spiral water channel 610, and the other end of the torsion spring 622 is fixedly connected to the gear 621.

[0035] A side shaft 623 is rotatably connected between the fixed frame 617 and the inclined plate 624. A second torsion spring 625 is sleeved on the outside of the side shaft 623. One end of the second torsion spring 625 is fixedly connected to the fixed frame 617, and the other end of the second torsion spring 625 is fixedly connected to the inclined plate 624. A piercing roller 626 is rotatably connected inside the inclined plate 624. A universal coupling 627 is fixedly installed between the rotating shaft 620 and the piercing roller 626.

[0036] Example 1: As Figure 3 - Figure 10 As shown, the operator inputs the external mixed gas into the intake pipe 4, and the exhaust pipe 5 is connected to the external induced draft fan. The mixed gas enters the processing box 3, and at the same time, the servo motor 63 is started to rotate. The servo motor 63 drives the rotating rod 64, the lower reciprocating screw 65 and the upper reciprocating screw 614 to rotate. Since the spiral channel 610 limits the slider 68, the rotation of the lower reciprocating screw 65 will cause the lower sleeve 66 and the connecting rod 67 to move up and down. The connecting rod 67 drives the slider 68 to move back and forth. When the slider 68 descends, it will rotate to match the inclination of the spiral channel 610. The mixed gas is drawn into the filter cartridge 62, and the droplets are thrown onto the filter cartridge 62 and the vertical cylinder 61. The hydrogen spirals upward and is discharged through the exhaust pipe 5.

[0037] Similarly, the inclined ring track 612 limits the fixed frame 617. The rotation of the upper reciprocating screw 614 will drive the upper sleeve 615, the connecting strip 616 and the fixed frame 617 to move up and down reciprocally. The fixed frame 617 drives the inclined plate 624 to move in an inclined circle. The torque of the second torsion spring 625 presses the inclined plate 624 tightly against the bottom surface of the wire mesh section 11, which is convenient for scraping and cleaning the bottom outer ring of the wire mesh section 11. When the gear 621 meshes with the spacer tooth block 613, it will drive the rotating shaft 620 to rotate. The rotating shaft 620 acts on the first torsion spring 622.

[0038] Furthermore, the rotating shaft 620 drives the piercing roller 626 to rotate via the universal coupling 627. When the gear 621 separates from the spacer block 613, the torsion spring 622 drives the rotating shaft 620 to rotate and reset, causing the piercing roller 626 to rotate. This achieves the segmented and sequential piercing of the water film remaining in the outer ring filter holes by the piercing roller 626, reducing the resistance of the water film to the subsequent hydrogen flow. Without significantly hindering the rising hydrogen, it can maintain a continuous and good treatment effect.

[0039] The lower sleeve 66 drives the slider 68 to move in the spiral water channel 610, which facilitates the downward spiral discharge of some of the scraped water and guides the airflow to generate a downward axial velocity component, reducing the secondary entrainment of the bottom water by short-circuit flow and hydrogen, facilitating the rapid separation of water and hydrogen, and improving the efficiency of centrifugal separation. The separated water flows into the collection box 9 through the drain pipe 8. The collection box 9 is equipped with a filter plate for filtration. The water can be discharged by opening the shut-off valve on the outside of the discharge pipe 10.

[0040] like Figure 1 and Figure 11 - Figure 14 As shown, a condenser assembly 7 is provided on the outside of the air intake pipe 4. The condenser assembly 7 includes a fixing sleeve 71 that is sleeved and fixed on the outside of the air intake pipe 4. A water inlet pipe 72 is fixedly connected to the top of the fixing sleeve 71, and a water outlet pipe 73 is fixedly connected to the bottom of the fixing sleeve 71. A solenoid 75 is sleeved on the outside of the air intake pipe 4, and an annular cover 74 is fixedly connected to both sides of the solenoid 75.

[0041] The annular cover 74 is rotatably connected to the air intake pipe 4. One side of the annular cover 74 is connected to the water inlet pipe 72, and the inner side of the annular cover 74 on this side is rotatably connected to the axial flow fan blade 76, which is located inside the air intake pipe 4. The other side of the annular cover 74 is connected to the water outlet pipe 73. The annular cover 74 is in contact with the inner wall of the fixed sleeve 71, so that when the annular cover 74 rotates, it can still be connected to the water inlet pipe 72 or the water outlet pipe 73 to maintain the circulation of cooling water.

[0042] A drain pipe 8 is fixedly connected to one side of the bottom of the treatment box 3. A collection box 9 is fixedly connected to the bottom end of the drain pipe 8. A filter plate is fixedly installed inside the collection box 9. A discharge pipe 10 is fixedly installed on the outside of the collection box 9. A shut-off valve is fixedly installed on the outside of both the drain pipe 8 and the discharge pipe 10.

[0043] Example 2: Figure 11 - Figure 14As shown, the operator connects the external cooling water to the inlet pipe 72 and the outlet pipe 73 to the external return pipe. The cooling water flows through the inlet pipe 72 into the annular cover 74 on one side, then into the solenoid 75 and the annular cover 74 on the other side, and finally flows out from the outlet pipe 73 into the return pipe. After the mixed gas enters the intake pipe 4, the gas flow drives the axial fan blade 76 to rotate. The axial fan blade 76 drives the annular cover 74 on one side to rotate, and at the same time, the annular cover 74 on the other side of the solenoid 75 also rotates. This prolongs the contact condensation time and expands the contact area, which facilitates the pre-condensation operation of the mixed gas and facilitates the subsequent gas-liquid separation operation.

[0044] Working principle: When using this device, firstly, as... Figure 1 - Figure 14 As shown, the operator connects the external cooling water to the inlet pipe 72, the outlet pipe 73 to the external return pipe, and the exhaust pipe 5 to the external induced draft fan. The cooling water flows through the inlet pipe 72 into the annular cover 74 on one side, facilitating the pre-condensation of the mixed gas and the subsequent gas-liquid separation. The mixed gas enters the processing tank 3, and at the same time, the servo motor 63 is started to rotate. The servo motor 63 drives the rotating rod 64, the lower reciprocating screw 65, and the upper reciprocating screw 614 to rotate. When the slider 68 descends, it will rotate to match the inclination of the spiral water channel 610. The mixed gas is drawn into the filter cartridge 62, and the liquid droplets are thrown onto the filter cartridge 62 and the vertical cylinder 61. The hydrogen spirals upward and is discharged through the exhaust pipe 5. The rotation of the upper reciprocating screw 614 will drive the upper sleeve 615, the connecting bar 616, and the fixed The frame 617 moves up and down reciprocally. The fixed frame 617 drives the inclined plate 624 to move in a tilted circle. The torque of the second torsion spring 625 presses the inclined plate 624 tightly against the bottom surface of the wire mesh section 11, which is convenient for scraping and cleaning the bottom outer ring of the wire mesh section 11. The piercing roller 626 pierces the water film remaining in the filter holes of the outer ring in segments and sequentially, reducing the resistance of the water film to the subsequent hydrogen flow. It can maintain a continuous and good treatment effect without significantly hindering the rising hydrogen. The lower sleeve 66 will drive the slider 68 to move in the spiral water channel 610, which is convenient for spirally discharging a portion of the scraped water downwards and guiding the airflow to generate a downward axial velocity component. This reduces the short-circuit flow and the secondary entrainment of hydrogen to the bottom water, which is convenient for the rapid separation of water and hydrogen and improves the efficiency of centrifugal separation.
