A gas separation adsorption tower

Abstract

The present invention belongs to the technical field of pressure swing adsorption separation, and specifically relates to a gas separation adsorption tower, which includes a tower body component. A support suspension is fixedly connected to the bottom of the tower body component; the tower body component includes a metal outer shell, and a top cover that can be opened is sleeved through an opening at the top of the metal outer shell, and an air delivery through pipe is fixedly connected to the axis center of the inner cavity of the top cover that can be opened. Since the gas flow will drive the particles inside the adsorbent to surely follow the gas flow direction and thus cause a follow-up phenomenon, the distribution of the adsorption particles inside the annular accommodating shell becomes more and more uneven, affecting the actual adsorption efficiency. Therefore, the upper and lower single-side covers are driven by power sources on the upper and lower sides to rotate in opposite directions, so that the adsorption particles inside are more evenly stressed. The adsorption particles can also deviate from the axis center position under the action of rotational centrifugal force, thereby effectively alleviating the phenomenon that the adsorption particles are always affected by the air flow and shift to one side.

Description

Technical Field

[0001] The present invention belongs to the technical field of pressure swing adsorption separation, and specifically relates to a gas separation adsorption tower. Background Art

[0002] The PSA pressure swing adsorption tower is a commonly used gas separation device, which consists of multiple components, including adsorbents, adsorption towers, pneumatic valves, and pressure control systems, etc. The adsorbent is the core component in the PSA pressure swing adsorption tower, and it realizes gas separation through adsorption. Commonly used adsorbents include activated carbon, molecular sieves, etc., and their selection is determined according to actual needs and gas components. The adsorbent has a large specific surface area and a certain pore structure, which can adsorb gas molecules and achieve separation. Gas separation is achieved by pressurized adsorption and vacuum desorption to produce required gases such as oxygen.

[0003] Since the gas flow will drive the particles inside the adsorbent to surely follow the direction of gas flow and thus cause a follow-up phenomenon, which will further lead to an increasingly uneven distribution of the adsorbent, and the aggregated adsorbent particles are very likely to block the ventilation port, resulting in poor gas fluidity and affecting the actual adsorption efficiency, so improvement is needed. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is: a gas separation adsorption tower, including a tower body component, and a support suspension is fixedly connected to the bottom of the tower body component; the tower body component includes a metal outer shell, a detachable top cover is sleeved on the top of the metal outer shell through an opening, a gas transmission pipe is fixedly connected to the axis center of the inner cavity of the detachable top cover, separation components are uniformly arranged on the axis center of the inner wall of the metal outer shell, an exhaust component is arranged at the axis center of the bottom of the inner wall of the metal outer shell, and a gas detection component is arranged at the bottom of the inner wall of the metal outer shell;

[0005] The separation component includes a single-sided cover plate, a torsion motor is rotatably connected to the axis center of the outer surface of the single-sided cover plate, a docking side shell is rotatably connected to the inner wall of the single-sided cover plate through a guiding chute, annular accommodating shells are uniformly arranged on the axis center of the inner wall of the single-sided cover plate, adsorption particles are arranged on the inner wall of the annular accommodating shells, and shunt pipes are uniformly arranged in the inner cavity of the docking side shell through semi-section through ports. It can be seen that each separation component is formed by docking and combining single-sided cover plates on the upper and lower sides, the shunt pipes are fixed through the merged semi-section through ports, and the upper single-sided cover plate is driven by the torsion motor to rotate clockwise; Figure 3 It can be seen that each separation component is formed by docking and combining single-sided cover plates on the upper and lower sides, the shunt pipes are fixed through the merged semi-section through ports, and the upper single-sided cover plate is driven by the torsion motor to rotate clockwise;

[0006] At the axis of the inner cavity of the bottom single-side cover plate, a docking chassis is fixedly connected. On the left and right sides of the upper surface of the docking chassis, distance-adjusting vertical plates are symmetrically arranged. At the top of the distance-adjusting vertical plates, reverse rotating wheels are rotatably connected through small motors, and the lower single-side cover plate is driven by the reverse rotating wheels to rotate counterclockwise.

[0007] Further, the number of the separation components is three groups, and the three groups of separation components are connected in sequence to increase the gas separation process. The top of the top flow distribution pipe is connected to the inner cavity of the gas transmission pipe through a docking inner disc. The inner cavity of the annular accommodation shell is evenly provided with air inlet holes. The outer surface of the reverse rotating wheel is in rolling connection with the lower surface of the bottom single-side cover plate. The bottom end of the docking chassis is inserted into the top of the inner cavity of the docking inner disc. Each separation component has six flow distribution pipes, and a through port is opened at the axis of the inner cavity of the bottom single-side cover plate. The inner cavity of the docking side shell is evenly provided with uniform grooves, and filling magnetic blocks are fixedly connected inside the uniform grooves. The outer surface of the annular accommodation shell is fixedly connected to the inner wall of the single-side cover plate.

[0008] Further, the gas detection component includes a bottom partition plate. Through holes are evenly arranged in the inner cavity of the bottom partition plate with filling pipe shells. A filter plug is fixedly connected to the inner wall of the filling pipe shell. An oxygen absorption disc is fixedly connected to the bottom of the filling pipe shell. On the front and back sides of the inner cavity of the oxygen absorption disc, external connecting wires are symmetrically arranged, and on the side of the external connecting wire far away from the oxygen absorption disc, an indicator light bar is fixedly connected. The oxygen absorption disc can detect the oxygen content of the gas introduced into it, and the oxygen concentration introduced into the oxygen absorption disc is proportional to the brightness of the indicator light bar. The outer surface of the bottom partition plate is fixedly connected to the bottom of the inner wall of the metal shell. The number of the filling pipe shells is six, and the top ends of the filling pipe shells are fixedly connected to the inner cavity of the bottom partition plate through through holes. The end of the external connecting wire far away from the oxygen absorption disc extends to the outside of the metal shell.

[0009] Further, the exhaust component includes a centralized bottom cover. A pressure sensing component is arranged at the bottom of the inner cavity of the centralized bottom cover. At the axis of the bottom of the inner cavity of the centralized bottom cover, an exhaust shaft pipe is fixedly connected. Horizontally inserted slots are evenly arranged in the lower part of the inner cavity of the exhaust shaft pipe, and segmented hollow pipes are evenly fixed inside the horizontally inserted slots. The end of the segmented hollow pipe far away from the horizontally inserted slot is fixedly connected with a sliding plug board. Under normal circumstances, the end of the sliding plug board far away from the exhaust shaft pipe is located inside the metal shell, but when the pressure in the exhaust shaft pipe increases, the segmented hollow pipe will push the corresponding sliding plug board, so as to penetrate the inserted slot opening of the support suspension, strengthening the connection between the metal shell and the support suspension. The bottom end of the exhaust shaft pipe extends to the outside of the metal shell. The number of the segmented hollow pipes is six. The outer surface of the sliding plug board is slidably connected to the bottom of the inner wall of the metal shell. The end of the sliding plug board far away from the segmented hollow pipe is slidably connected to the bottom of the inner cavity of the metal shell through a through groove.

[0010] Further, the pressure-sensitive component includes a packing ring. A spring sleeve is fixedly connected to the lower surface of the packing ring. The bottom end of the spring sleeve is fixedly connected to a pressure-receiving collar, and the center of the inner wall of the pressure-receiving collar is fixedly connected to the outer surface of the exhaust shaft pipe. The top end of the packing ring extends into the concentrated bottom cover. The top of the concentrated bottom cover is fixedly connected to the center of the lower surface of the bottom partition. The lower surface of the concentrated bottom cover is fixedly connected to the outer surface of the pressure-receiving collar through a fixed baffle. The lower surface of the packing ring is slidably connected to the upper part of the inner wall of the pressure-receiving collar.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. The device separates oxygen from the incoming gas through the upper and lower docking separation components. Since the gas flow will drive the particles inside the adsorbent, and the particles will surely follow the gas flow direction, which will lead to an increasingly uneven distribution of the adsorbed particles inside the annular accommodation shell. Moreover, the aggregated adsorbed particles are likely to block the air inlet of the annular accommodation shell, affecting the actual adsorption efficiency. Therefore, the upper and lower power sources drive the upper and lower single-sided covers to rotate in opposite directions, so that the internal adsorbed particles are more evenly stressed. The adsorbed particles can also deviate from the axis position under the action of the rotational centrifugal force, effectively alleviating the phenomenon that the adsorbed particles are always affected by the air flow and shift to one side.

[0013] 2. Since the separation components inside the device are assembled in a combined manner, and the internal adsorbed particles need to be maintained and replaced during continuous operation. After taking out the separation components from the inside of the metal shell, the docking side shells on both sides can be separated to easily replace the internal adsorbed particles without replacing the entire separation component, thus solving the problem that the overall replacement of the separation component results in excessive costs and it is difficult to use the device for gas separation for a long time.

[0014] 3. Under normal circumstances, the separated oxygen will only be discharged outward through the exhaust component under the action of air pressure. However, when there is a leakage problem inside the separation component, the oxygen will directly diffuse into the inside of the metal shell. As the concentration of the oxygen overflowing from the separation component increases, the indicator light bar will become brighter, thereby prompting the external personnel to timely conduct the airtightness detection work of the device and eliminate the leakage fault to avoid adverse problems such as oxygen loss.

[0015] 4. When the oxygen pressure inside the concentrated bottom cover is too high, the pressure will push the packing ring to slide downward, press the pressure-receiving collar through the spring sleeve, and then reflect the pressure inside the concentrated bottom cover through the extrusion force received by the pressure-receiving collar. Then, the external operator can timely conduct the pressure relief work to avoid the problem that the pressure exceeds the load of the device and causes damage to the internal devices of the device.

Specific Embodiments

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations will be obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0026] Example 1, please refer to Figures 1 - 4, the present invention provides a technical solution: a gas separation adsorption tower, including a tower body component 1, and a support suspension 2 is fixedly connected to the bottom of the tower body component 1; the tower body component 1 includes a metal outer shell 11, a detachable top cover 12 is sleeved on the top of the metal outer shell 11 through an opening, a gas transmission pipe 13 is fixedly connected to the axis of the inner cavity of the detachable top cover 12, separation components 3 are uniformly arranged at the axis of the inner wall of the metal outer shell 11, an exhaust component 5 is arranged at the axis of the bottom of the inner wall of the metal outer shell 11, and a gas detection component 4 is arranged at the bottom of the inner wall of the metal outer shell 11;

[0027] The separation component 3 includes a single-side cover plate 31, a torsion motor 36 is rotatably connected to the axis of the outer surface of the single-side cover plate 31, a docking side shell 32 is rotatably connected to the inner wall of the single-side cover plate 31 through a guiding chute, annular accommodating shells 33 are uniformly arranged at the axis of the inner wall of the single-side cover plate 31, adsorption particles 34 are arranged on the inner walls of the annular accommodating shells 33, and shunt pipes 35 are uniformly arranged in the inner cavity of the docking side shell 32 through semi-sectional through ports. Figure 3 As can be seen, each separation component 3 is formed by docking and combining single-side cover plates 31 on the upper and lower sides, the shunt pipes 35 are fixed through the combined semi-sectional through ports, and the upper single-side cover plate 31 is driven by the torsion motor 36 to rotate clockwise;

[0028] A docking chassis 37 is fixedly connected to the axis of the inner cavity of the bottom single-side cover plate 31, adjusting vertical plates 38 are symmetrically arranged on the left and right sides of the upper surface of the docking chassis 37, a reverse runner 39 is rotatably connected to the top of the adjusting vertical plate 38 through a small motor, and the lower single-side cover plate 31 is driven by the reverse runner 39 to rotate counterclockwise.

[0029] The number of the separation components 3 is three groups, and the three groups of separation components 3 are sequentially connected to increase the gas separation process. The top end of the top shunt pipe 35 is communicated with the inner cavity of the gas transmission pipe 13 through a docking inner disk. Air inlet holes are uniformly opened in the inner cavity of the annular accommodating shell 33. The outer surface of the reverse runner 39 is in rolling connection with the lower surface of the bottom single-side cover plate 31. The bottom end of the docking chassis 37 is inserted into the top of the inner cavity of the docking inner disk. Each separation component 3 has six shunt pipes 35, and a through port is opened at the axis of the inner cavity of the bottom single-side cover plate 31. Uniform grooves are uniformly opened in the inner cavity of the docking side shell 32, and filling magnets are fixedly connected inside the uniform grooves. The outer surface of the annular accommodating shell 33 is fixedly connected to the inner wall of the single-side cover plate 31.

[0030] After assembling the device, raw material gas can be directly introduced into the device through the gas transmission pipe 13 at the top. Then, the gas first flows downward through the three groups of interconnected separation components 3. After being processed by the separation components 3, the prepared oxygen will be discharged from the bottom of the support suspension 2 through the exhaust component 5, and then gas collection work can be carried out.

[0031] Taking the uppermost separation component 3 as an example, after the gas directly enters the interior of the container formed by the combined upper and lower docking side shells 32 and the single-sided cover plate 31 through the shunt pipe 35, under the action of air pressure, it will sequentially pass through the annular accommodating shell 33 from the outside to the inside, and carry out gas separation work through the adsorption particles 34 inside the annular accommodating shell 33, and then enter the space in the middle of the container, and be discharged downward through the through hole of the bottom single-sided cover plate 31 into the docking inner plate, and then be shunted to the lower separation component 3, so as to sequentially pass through three groups of separation components 3.

[0032] When the gas passes through, the torsion motor 36 drives the upper single-sided cover plate 31 to rotate clockwise, thereby synchronously twisting the upper annular accommodating shell 33 and the internal adsorption particles 34. The reverse runner 39 drives the lower single-sided cover plate 31 to rotate counterclockwise. At this time, the annular accommodating shells 33 docked on the upper and lower sides rotate in opposite directions, and the docking side shell 32 will slide relative to the single-sided cover plate 31 under the restrictive action of the shunt pipe 35, so as to keep the overall static state. Therefore, when the high-pressure gas flowing from the outside to the inside passes through the annular accommodating shell 33, the internal adsorption particles 34 not only receive relatively uniform force, but also can deviate from the axis position under the action of rotational centrifugal force, thereby effectively alleviating the phenomenon that the adsorption particles 34 are always affected by the air flow and shift to one side.

[0033] When replacing the separation component 3, the top openable top cover 12 can be opened, and the separation component 3 can be pulled out from the inside of the metal shell 11, and then the inside of the docking side shell 32 can be demagnetized, so as to open the single-sided cover plates 31 on both sides, replace the adsorption particles 34 inside the annular accommodating shell 33 and recombine them together, so that the adsorption particles 34 in the separation component 3 can regain the ability to separate oxygen.

[0034] Example 2, please refer to Figures 1 - 8 , the present invention provides a technical solution: on the basis of Example 1, the gas detection component 4 includes a bottom partition 41, and the inner cavity of the bottom partition 41 is uniformly provided with filling tube shells 42 through through holes. The inner wall of the filling tube shell 42 is fixedly connected with a filter plug 43, and the bottom of the filling tube shell 42 is fixedly connected with an oxygen absorption plate 44. The front and rear sides of the inner cavity of the oxygen absorption plate 44 are symmetrically provided with external connecting wires 45, and one side of the external connecting wire 45 away from the oxygen absorption plate 44 is fixedly connected with an indicator light bar 46. The oxygen absorption plate 44 can detect the oxygen content of the gas introduced into it, and the oxygen concentration introduced into the oxygen absorption plate 44 is proportional to the brightness of the indicator light bar 46. The outer surface of the bottom partition 41 is fixedly connected with the bottom of the inner wall of the metal shell 11. The number of the filling tube shells 42 is six, and the top of the filling tube shell 42 is fixedly connected with the inner cavity of the bottom partition 41 through a through hole. One end of the external connecting wire 45 away from the oxygen absorption plate 44 extends to the outside of the metal shell 11.

[0035] The exhaust component 5 includes a centralized bottom cover 51. At the bottom of the inner cavity of the centralized bottom cover 51, a pressure-sensitive component 6 is provided. At the axis of the bottom of the inner cavity of the centralized bottom cover 51, an exhaust shaft tube 52 is fixedly connected. At the lower part of the inner cavity of the exhaust shaft tube 52, horizontal slots 53 are evenly opened, and segmented hollow tubes 54 are evenly fixed in the inner cavities of the horizontal slots 53. One end of the segmented hollow tube 54 away from the horizontal slot 53 is fixedly connected with a sliding plug board 55. Under normal circumstances, the end of the sliding plug board 55 away from the exhaust shaft tube 52 is located inside the metal shell 11. However, when the pressure in the exhaust shaft tube 52 increases, the segmented hollow tube 54 will push the corresponding sliding plug board 55, thereby penetrating the slot opening of the support suspension 2 and strengthening the connection between the metal shell 11 and the support suspension 2. The bottom end of the exhaust shaft tube 52 extends to the outside of the metal shell 11. The number of the segmented hollow tubes 54 is six. The outer surface of the sliding plug board 55 is slidably connected to the bottom of the inner wall of the metal shell 11. One end of the sliding plug board 55 away from the segmented hollow tube 54 is slidably connected to the bottom of the inner cavity of the metal shell 11 through a through slot.

[0036] The pressure-sensitive component 6 includes a filling ring 61. The lower surface of the filling ring 61 is fixedly connected with a spring sleeve 62. The bottom end of the spring sleeve 62 is fixedly connected with a pressure-receiving collar 63. And at the axis of the inner wall of the pressure-receiving collar 63, it is fixedly connected with the outer surface of the exhaust shaft tube 52. The top end of the filling ring 61 extends to the inside of the centralized bottom cover 51. The top of the centralized bottom cover 51 is fixedly connected to the axis of the lower surface of the bottom partition board 41. The lower surface of the centralized bottom cover 51 is fixedly connected to the outer surface of the pressure-receiving collar 63 through a fixed baffle. The lower surface of the filling ring 61 is slidably connected to the upper part of the inner wall of the pressure-receiving collar 63.

[0037] Under normal circumstances, the separated oxygen will only be discharged outward through the exhaust component 5 under the action of air pressure. However, when there is a leakage problem inside the separation component 3, the oxygen will directly diffuse into the metal shell 11 and flow downward under the action of air pressure. At this time, the gas will be filled into the oxygen absorption disc 44 through the filling tube shell 42. Then the oxygen absorption disc 44 detects the oxygen and feeds it back to the indicator light bar 46 through the external wire 45 according to the oxygen concentration. And as the oxygen concentration increases, the indicator light bar 46 will also become brighter.

[0038] The oxygen is discharged to the outside through the centralized bottom cover 51 and the exhaust shaft tube 52. When the oxygen discharge flow rate of the device is slow, a large amount of oxygen will accumulate inside the centralized bottom cover 51 and the exhaust shaft tube 52, causing the pressure inside the exhaust shaft tube 52 to increase, thereby pushing open the segmented hollow tube 54 and making the sliding plug board 55 slide outward. Then the sliding plug board 55 is inserted into the slot of the support suspension 2, further improving the stability of the metal shell 11 and the support suspension 2 and preventing the metal shell 11 from shaking. When the sliding plug board 55 is not inserted into the support suspension 2, the metal shell 11 can be easily removed in the non-working state for inspection and maintenance work.

[0039] When the oxygen pressure inside the centralized bottom cover 51 is too high, the pressure will push the filling ring 61 to slide downward, press the pressure-receiving sleeve ring 63 through the spring sleeve 62, and then the pressure inside the centralized bottom cover 51 is reflected by the extrusion force received by the pressure-receiving sleeve ring 63. Then, the external operator can perform the pressure relief work in time to avoid the problem of device damage inside the device caused by the pressure exceeding the load of the device.

[0040] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention shall be implemented by conventional means in the art without special instructions and limitations.
