Description

Technical Field

[0001] The invention relates to the field of steam-water separation devices, in particular to a steam-water separation device for treating hydrogen production tail gas. Background Art

[0002] In the process of hydrogen production, especially hydrogen produced by certain chemical reactions (such as hydrogen production by natural gas reforming) or physical processes (such as hydrogen production by water electrolysis), the tail gas often contains a certain amount of water vapor or other liquid impurities. If these impurities are not treated, they may affect the subsequent use of hydrogen, such as reducing the purity of hydrogen, affecting the storage and transportation of hydrogen, etc.

[0003] The water vapor in the existing hydrogen production tail gas is usually separated by a steam-water separator. The application of the steam-water separator in the treatment of hydrogen production tail gas is mainly reflected in the following aspects:

[0004] Improve hydrogen purity: Through steam-water separation, water vapor and other liquid impurities in hydrogen can be effectively removed, thereby improving the purity of hydrogen to meet the requirements of subsequent use or storage.

[0005] Protect equipment: In subsequent processing equipment such as hydrogen compressors, if the hydrogen contains a lot of water, it may cause corrosion or damage to the equipment. The steam-water separator can reduce the damage of this water to the equipment and extend the service life of the equipment.

[0006] Improve safety: Hydrogen is a flammable and explosive gas. If its purity is insufficient or contains more impurities, it may increase the safety risk during use. The steam-water separator helps reduce this risk by improving the purity of hydrogen.

DETAILED DESCRIPTION

[0040] 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.

[0041] As mentioned in the background technology of the present application, it has been found through research that the existing baffle-type steam-water separator cannot adjust the spacing between the baffles 16 as needed during use to achieve the best condensation effect and separation efficiency, and has certain defects.

[0042] In order to solve the above defects, the present application discloses a steam-water separation device for treating hydrogen production tail gas. By setting a gathering and dispersing driving mechanism, the distance between each baffle 16 can be adjusted as needed to achieve the best condensation effect and separation efficiency.

[0043] The following will describe in detail how the solution of the present application solves the above technical problems in conjunction with the accompanying drawings.

[0044] See also Figures 1 to 13In an embodiment of the present invention, a steam-water separation device for treating hydrogen production tail gas includes a body 2, a separation chamber 4 is provided inside the body 2, and two groups of baffles 16 are provided inside the separation chamber 4, each group of baffles 16 has three baffles, and each baffle 16 is staggered, and a filter assembly is provided below the body 2; both sides of the body 2 are provided with a flip mechanism for rotating the body 2, and one side of the separation chamber 4 is provided with a gathering and dispersion driving mechanism for driving each baffle 16 to move closer to or away from each other, and a transverse cleaning mechanism is provided outside the baffle 16 for cleaning the surface of the baffle 16. The present application sets two groups of staggered baffles 16 so that the steam can change the flow direction multiple times in the separation chamber 4, thereby increasing the chance of collision between the water droplets and the baffle 16. In addition, through the setting of the gathering and dispersion driving mechanism, the spacing between each baffle 16 can be adjusted as needed to achieve the best condensation effect and separation efficiency.

[0045] In this embodiment, the gathering and dispersing driving mechanism specifically includes: a vertical slot 12 opened in the middle position of the inner wall of one side of the separation chamber 4, a first dual-axis motor 13 is embedded in the middle position inside the vertical slot 12, and the two output shafts of the first dual-axis motor 13 are fixedly connected with a screw 14, each screw 14 surface is provided with three threaded sections with different pitches, the external thread of each threaded section is connected with a lifting block 15 matching the vertical slot 12, and the lifting block 15 is fixedly connected with the corresponding baffle 16, and a stopper is provided between one side of the baffle 16 and the inner wall of the separation chamber 4. The spacing between the baffles 16 determines the frequency and angle of the collision between the steam and the baffle 16 when passing through. A smaller spacing may increase the number of collisions between the steam and the baffle 16, making it easier for water droplets to accumulate and condense on the baffle 16. However, too small a spacing may also cause the steam flow to be obstructed, increase pressure loss, and even cause the steam flow rate to be too fast and unable to be fully condensed. The adjustment of the spacing will also affect the flow rate and distribution of the steam in the separator. The appropriate spacing can keep the steam at an appropriate flow rate when passing through the baffle 16, neither too fast nor too slow, which is conducive to the condensation and separation of water droplets. If the spacing is too large, the steam may not be able to fully contact the baffle 16, resulting in a reduced condensation effect; if the spacing is too small, it may increase the resistance to steam flow and reduce the overall efficiency. When designing a baffle 16 steam-water separator, it is necessary to weigh the relationship between separation efficiency and pressure drop. Smaller spacing can usually improve separation efficiency, but it will also increase pressure drop and increase energy consumption. Therefore, when adjusting the spacing, it is necessary to comprehensively consider the separation effect and energy consumption cost to find the best balance. In practical applications, adjusting the spacing between the baffles 16 usually requires testing and optimization according to specific operating conditions. This includes factors such as steam flow, temperature, pressure, and the required separation efficiency. Through simulation or experimental testing, the baffle 16 spacing suitable for specific working conditions can be found to achieve the best condensation effect and separation efficiency.

[0046] In this embodiment, the limiting member specifically includes: two limiting slide rails 17 fixed in parallel on the inner walls of both sides of the separation chamber 4, and a limiting slide groove 18 matching the limiting slide rail 17 is provided on one side of the baffle 16 corresponding to the limiting slide rail 17, and the limiting slide rail 17 is movably connected in the limiting slide groove 18. When the spacing between the baffles 16 is adjusted, the baffle 16 moves up and down along the separation chamber 4, and during the process, the limiting slide rail 17 and the limiting slide groove 18 are relatively displaced to improve stability.

[0047] In this embodiment, the transverse cleaning mechanism specifically includes: a concave plate 19 movably connected to the outside of the baffle 16, a strip gap groove between the baffle 16 and the inner wall of one side of the separation chamber 4 for the concave plate 19 to move transversely, and four wheel grooves 20 distributed in a rectangular pattern are provided on the inner walls on both sides of the concave groove of the concave plate 19, rollers 21 are rotatably connected inside the wheel grooves 20, bristles 22 are fixedly connected to the edges of the inner walls on both sides of the concave groove of the concave plate 19, a transverse linear guide 23 is fixedly connected to the middle position of one side of the baffle 16 in the strip gap groove, and a transverse linear motor 24 is movably connected to the outside of the transverse linear guide 23, and the transverse linear motor 24 is fixedly connected to the inner wall of the concave plate 19. The transverse cleaning mechanism set in this application can clean the surface of the baffle 16 when needed, thereby removing dirt and accumulated water on the baffle 16, so that the baffle 16 maintains its good condensation effect and is easy to use.

[0048] In this embodiment, a rectangular limiting plate 25 is fixedly connected to a side of the baffle 16 away from the lateral cleaning mechanism, and through grooves 26 are provided on the upper and lower sides of the rectangular limiting plate 25. The rectangular limiting plate 25 can prevent the concave plate 19 from separating from the baffle 16, and the through grooves 26 can facilitate the water accumulated on the baffle 16 to flow downward smoothly.

[0049] In this embodiment, the flip mechanism specifically includes: two columns 1 respectively fixed on both sides of the body 2, a stepper motor 3 is embedded in the upper part of the column 1, and the output shaft of the stepper motor 3 passes through the column 1 and is fixedly connected to the body 2, and a limit guide is provided between the body 2 and the column 1. After the separation device of the present application separates the droplets, a large amount of accumulated water is formed at the bottom of the separation chamber 4 after accumulation over time. The accumulated water can be reused by the set flip mechanism, that is, the entire body 2 is flipped 180 degrees by the flip mechanism, so that the accumulated water flows to flush the baffle 16. It should be noted that the side of the baffle 16 that is most likely to have dirt when in use is the bottom end face. When the body 2 is flipped 180 degrees, the original bottom end face of the baffle 16 becomes the top end face and is flushed by the accumulated water.

[0050] In this embodiment, the position limiting guide specifically includes: an optical axis 9 fixed on both sides of the body 2 near the middle position, a semicircular track groove 10 for the movement of the optical axis 9 is opened at a position corresponding to the optical axis 9 on one side of the column 1, one end of the optical axis 9 is movably connected inside the semicircular track groove 10, and electromagnets 11 are embedded at both ends of the semicircular track groove 10. The position limiting guide provided in the present application can not only improve the stability of the body 2 during rotation, but also can fix and limit the position of the body 2 in a vertical state to avoid deviation.

[0051] In this embodiment, the filter assembly specifically includes: a filter box 27 arranged below the body 2, a lifting slot 29 is provided on one side of the column 1 facing the filter box 27, and a lifting plate 28 is movably connected in the lifting slot 29, a cylinder 30 is embedded in the top wall of the lifting slot 29, and the bottom output shaft of the cylinder 30 is fixedly connected to the lifting plate 28, the lifting plate 28 is fixedly connected to the filter box 27, and a filter chamber 32 is provided inside the filter box 27, a notch 31 communicating with the filter chamber 32 is provided at the center of the top surface of the filter box 27, and two parallel strip filter plates 33 are movably connected inside the filter chamber 32, and the inner walls on both sides of the filter chamber 32 are fixedly connected to the positions of the strip filter plates 33. The pin 39 and the ejector pin 39 correspond to and match the filter holes of the strip filter plate 33, and a water outlet groove 40 is provided below the ejector pin 39. The two sides of the top surface of the strip filter plate 33 are fixedly connected with the movable plate 35. The top surface of the filter box 27 is provided with a strip groove 34 for the movable plate 35 to move left and right, and the movable plate 35 passes through the strip groove 34. A fixed plate 37 is fixedly connected above one end of the strip groove 34. A second dual-axis motor 36 is fixedly connected between the two relatively movable plates 35, and the two ends of the second dual-axis motor 36 are respectively connected with a screw 38 with opposite threads, which passes through the corresponding movable plate 35 and is threadedly connected thereto, and one end of the screw 38 is rotatably connected to the corresponding fixed plate 37. The setting of the filter assembly can effectively filter the discharged wastewater and clear the filter holes on the strip filter plate 33 when necessary.

[0052] In this embodiment, the top of the machine body 2 is fixedly connected with a first sewage outlet 5, and the bottom of the machine body 2 is fixedly connected with a second sewage outlet 6. Both the first sewage outlet 5 and the second sewage outlet 6 can be used to discharge sewage.

[0053] In this embodiment, a second air pipe 7 communicating with the separation chamber 4 is fixedly connected to a side of the body 2 near the bottom, and a first air pipe 8 communicating with the separation chamber 4 is fixedly connected to a side of the body 2 near the top. Both the first air pipe 8 and the second air pipe 7 can be used to introduce and export gas.

[0054] The working principle of the present invention is: when in use, first, the hydrogen production tail gas is sent into the separation chamber 4 through the second air pipe 7, and the hydrogen production tail gas rises along the gaps between the baffles 16 in the separation chamber 4. During the process, the flow direction of the hydrogen production tail gas will suddenly change. This sudden change in flow direction makes it impossible for the water droplets to change direction as quickly as dry steam due to their inertia and mass, thereby achieving separation. The separated water droplets will accumulate on the baffle 16 and flow downward to the bottom of the separation chamber 4, and the final remaining gas will be discharged from the first air pipe 8.

[0055] It should be noted that adjusting the spacing between the two baffles 16 can have a significant impact on the condensation effect in the baffle type steam-water separator. A smaller spacing may increase the number of collisions between the steam and the baffle 16, making it easier for water droplets to accumulate and condense on the baffle 16. However, too small a spacing may also cause steam flow obstruction, increase pressure loss, and even cause the steam flow rate to be too fast and unable to fully condense. For this reason, in actual use, the staff needs to adjust the spacing of the baffles 16 according to specific working conditions. The specific adjustment process is as follows: if the first dual-axis motor 13 is running and drives the screw 14 to rotate clockwise, the threaded segment on the screw 14 rotates so that the lifting block 15 thereon moves toward the first dual-axis motor 13, thereby causing each baffle 16 to gather toward the middle, and the distance between the two baffles 16 becomes smaller; if the first dual-axis motor 13 is running and drives the screw 14 to rotate counterclockwise, the threaded segment on the screw 14 rotates so that the lifting block 15 thereon moves away from the first dual-axis motor 13, thereby causing each baffle 16 to disperse upward and downward, and the distance between the two baffles 16 becomes larger. It should be noted that the farther the threaded segment on each screw 14 is from the first dual-axis motor 13, the faster the corresponding lifting block 15 moves during the rotation process. This is to ensure that when the baffle 16 moves to adjust the spacing, the spacing between two adjacent baffles 16 can remain consistent.

[0056] After being used for a period of time, the dirt and water on the baffle 16 will affect the condensation effect of the baffle 16 and reduce the separation efficiency. For this reason, the present application handles this problem by setting up a transverse cleaning mechanism. Specifically, the transverse linear motor 24 runs and moves slowly along the transverse linear guide 23. During the process, the concave plate 19 follows the movement of the baffle 16, and the roller 21 on the concave plate 19 rolls in contact with the baffle 16 to reduce friction resistance. At the same time, the bristles 22 on the concave plate 19 clean the surface of the baffle 16. The bristles 22 are repeatedly cleaned to effectively remove the dirt and water on the baffle 16, so that the baffle 16 maintains its good condensation effect and is easy to use.

[0057] In addition, after the separation device of the present application separates the droplets, a large amount of accumulated water forms at the bottom of the separation chamber 4 after a period of time. The accumulated water can be reused by the set flip mechanism, that is, the entire body 2 is flipped 180 degrees by the flip mechanism, so that the accumulated water flows to flush the baffle 16. It should be noted that the side of the baffle 16 that is most prone to dirt during use is the bottom end face. When the body 2 is flipped 180 degrees, the original bottom end face of the baffle 16 becomes the top end face and is flushed by the accumulated water. The original top end face of the baffle 16 becomes the bottom end face and accepts the contact and separation work with water vapor in the next round of hydrogen production tail gas separation. The two sides of the baffle 16 are used alternately. After one side completes the work, the other side accepts the work. At the same time, the side that completes the work is flushed, so that the baffle 16 always maintains its good condensation effect. Among them, the operation process of the flipping mechanism is that the stepper motor 3 runs to drive the body 2 to flip one hundred and eighty degrees. During the process, the optical axis 9 follows and moves along the semicircular track groove 10. It should be noted that in the initial state, the electromagnet 11 at the top of the semicircular track groove 10 is energized to generate magnetism, which firmly adsorbs the optical axis 9 to prevent the body 2 from rotating easily; when the body 2 needs to be rotated, the electromagnet 11 at the top of the semicircular track groove 10 is powered off, and the electromagnet 11 at the bottom of the semicircular track groove 10 is energized to generate magnetism. When the optical axis 9 follows and moves along the semicircular track groove 10 to the bottom and contacts the electromagnet 11 below, the electromagnet 11 below firmly adsorbs the optical axis 9.

[0058] It should also be noted that when the body 2 is turned over 180 degrees, the second air pipe 7 originally used to feed the hydrogen production tail gas is now used to discharge the remaining gas, and the first air pipe 8 originally used to discharge the remaining gas is now used to feed the hydrogen production tail gas.

[0059] When sewage is discharged through the first sewage outlet 5 and the second sewage outlet 6, the filter assembly operates to filter the discharged sewage. Specifically, the cylinder 30 operates to retract the output shaft, driving the lifting plate 28 to slowly rise along the lifting groove 29 until the first sewage outlet 5 or the second sewage outlet 6 is docked with the slot 31. Subsequently, the sewage enters the filter chamber 32 from the slot 31 and flows out from the water outlet 40 after being filtered by the strip filter plate 33. However, as time goes by, the filter holes on the strip filter plate 33 are blocked more and more, affecting the overall filtering effect. At this time, the second dual-axis motor 36 operates to drive the lead screw 38 to rotate, and the moving plate 35 moves along the lead screw 38 in the strip groove 34 in a direction away from the second dual-axis motor 36. During the process, the strip filter plate 33 moves toward the ejector pin 39 until the ejector pin 39 is inserted into the filter hole of the strip filter plate 33 to eject the blockage therein, thereby completing the clearing work. When the filter assembly is not performing filtering work, the cylinder 30 operates to extend the output shaft to lower the filter box 27 to avoid affecting the turning of the machine body 2.
