Description

Technical Field

[0001] The invention belongs to the technical field of pressure swing adsorption separation, in particular to a gas separation adsorption tower. Background Art

[0002] PSA pressure swing adsorption tower is a commonly used gas separation equipment, which consists of multiple components, including adsorbent, adsorption tower, pneumatic valve and pressure control system. Adsorbent is the core component of PSA pressure swing adsorption tower, which realizes gas separation through adsorption. Commonly used adsorbents include activated carbon, molecular sieve, etc., and their selection should be determined according to actual needs and gas composition. The adsorbent has a large specific surface area and a certain pore structure, which can adsorb gas molecules and achieve separation. The gas is separated 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 move in the direction of the gas flow, the distribution of the adsorbent will become increasingly uneven. The aggregated adsorbent particles can easily block the vents, causing the gas flow to deteriorate and affecting the actual adsorption efficiency, so improvements are needed. Summary of the invention

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve the technical problems is as follows: a gas separation adsorption tower, comprising a tower body component, the bottom of which is fixedly connected to a support suspension; the tower body component comprises a metal shell, the top of which is sleeved with an openable top cover through an opening, a gas transmission pipe is fixedly connected to the axis of the inner cavity of the openable top cover, separation components are evenly arranged at the axis of the inner wall of the metal shell, an exhaust component is arranged at the axis of the bottom of the inner wall of the metal shell, and a gas detection component is arranged at the bottom of the inner wall of the metal shell;

[0005] The separation component comprises a single-side cover plate, a torsion motor is rotatably connected to the axis of the outer surface of the single-side cover plate, the inner wall of the single-side cover plate is rotatably connected to the docking side shell through a guide slot, an annular accommodating shell is evenly arranged at the axis of the inner wall of the single-side cover plate, adsorption particles are arranged on the inner wall of the annular accommodating shell, and a shunt pipe is evenly arranged in the inner cavity of the docking side shell through a half-cut through-hole. Figure 3 It can be seen that each separation component is formed by the joint assembly of the upper and lower single-side cover plates, the split flow pipe is fixed through the combined half-cut through-hole, and the upper single-side cover plate is driven by the torsion motor to rotate clockwise;

[0006] A docking chassis is fixedly connected to the axis of the inner cavity of the bottom single-sided cover plate, and distance-adjusting vertical plates are symmetrically arranged on the left and right sides of the upper surface of the docking chassis. The top of the distance-adjusting vertical plate is connected to a reverse rotating wheel through a small motor, and the single-sided cover plate below is driven by the reverse rotating wheel to rotate counterclockwise.

[0007] Furthermore, the number of 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 pipe is connected to the inner cavity of the gas transmission pipe through the docking inner plate, and the inner cavity of the annular containment shell is uniformly provided with air inlet holes. The outer surface of the reverse wheel is rollingly connected to the lower surface of the bottom single-side cover plate, and the bottom end of the docking bottom plate is plugged into the top of the inner cavity of the docking inner plate. Each separation component has six branch flow pipes, and a through opening is opened at the axis of the inner cavity of the bottom single-side cover plate, and the inner cavity of the docking side shell is uniformly provided with uniform grooves, and the inside of the uniform grooves is fixedly connected with filling magnetic blocks, and the outer surface of the annular containment shell is fixedly connected to the inner wall of the single-side cover plate.

[0008] Furthermore, the gas detection component includes a bottom partition, the inner cavity of the bottom partition is evenly provided with filling tube shells through the through-hole, the inner wall of the filling tube shell is fixedly connected with a filter plug, the bottom of the filling tube shell is fixedly connected with an oxygen absorption disk, the front and rear sides of the inner cavity of the oxygen absorption disk are symmetrically provided with external wires, and the side of the external wire away from the oxygen absorption disk is fixedly connected with an indicator light bar, the oxygen absorption disk can detect the content of oxygen in the gas passing into it, and the oxygen concentration passing into the oxygen absorption disk is proportional to the brightness of the indicator light bar. The outer surface of the bottom partition is fixedly connected to the bottom of the inner wall of the metal shell, the number of the filling tube shells is six, and the top of the filling tube shell is fixedly connected to the inner cavity of the bottom partition through the through-hole, and the end of the external wire away from the oxygen absorption disk extends to the outside of the metal shell.

[0009] Furthermore, the exhaust component includes a centralized bottom cover, a pressure-sensitive component is provided at the bottom of the centralized bottom cover inner cavity, an exhaust shaft tube is fixedly connected at the axis of the bottom of the centralized bottom cover inner cavity, a horizontal slot is evenly provided at the lower part of the exhaust shaft tube inner cavity, and a segmented hollow tube is evenly fixed to the inner cavity of the horizontal slot, and a sliding plug plate is fixedly connected to the end of the segmented hollow tube away from the horizontal slot. Under normal circumstances, the end of the sliding plug plate away from the exhaust shaft tube is located inside the metal shell, but when the pressure of the exhaust shaft tube increases, the segmented hollow tube will push the sliding plug plate on the corresponding side, thereby penetrating the slot opening of the support suspension, and strengthening the connection between the metal shell and the support suspension. The bottom end of the exhaust shaft tube extends to the outside of the metal shell, the number of the segmented hollow tubes is six, the outer surface of the sliding plug plate is slidably connected to the bottom of the inner wall of the metal shell, and the end of the sliding plug plate away from the segmented hollow tube is slidably connected to the bottom of the inner cavity of the metal shell through the through groove.

[0010] Furthermore, the pressure-sensitive component includes a filling ring, the lower surface of the filling ring is fixedly connected to a spring sleeve, the bottom end of the spring sleeve is fixedly connected to a pressure-bearing collar, and the axis of the inner wall of the pressure-bearing collar is fixedly connected to the outer surface of the exhaust shaft pipe.

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

[0012] 1. The device separates oxygen from the introduced gas through the separation components connected upper and lower. Since the gas flow will drive the particles inside the adsorbent to move along the direction of the gas flow, the distribution of the adsorbed particles inside the annular containment shell will become more and more uneven, and the gathered adsorbed particles can easily block the gas port of the annular containment shell, affecting the actual adsorption efficiency. Therefore, the power sources on the upper and lower sides will drive the single-sided cover plates on the upper and lower sides to rotate in the opposite direction, so that the force on the internal adsorbed particles is more uniform, and the adsorbed particles can also deviate from the axial position under the action of the centrifugal force of rotation, thereby effectively alleviating the phenomenon that the adsorbed particles are always affected by the airflow and deviate to one side.

[0013] 2. Since the separation components inside the device are assembled, and the internal adsorption particles need to be maintained and replaced when working continuously, after taking the separation components out from the inside of the metal shell, the internal adsorption particles can be easily replaced by separating the docking side shells on both sides without replacing the entire separation component, thereby solving the problem of excessive cost caused by replacing the separation components as a whole and difficulty in using the device for gas separation for a long time.

[0014] 3. Under the action of air pressure, the separated oxygen will normally only be discharged through the exhaust components. However, when there is a gas leakage inside the separation component, the oxygen will directly diffuse into the inside of the metal shell. As the concentration of oxygen overflowing from the separation component increases, the indicator light will become brighter, thereby prompting external personnel to conduct air tightness testing of the device in a timely manner, eliminate gas leakage faults, and 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 filling ring to slide downward, press the pressure ring through the spring sleeve, and then the extrusion force received by the pressure ring reflects the pressure inside the concentrated bottom cover. Then the external operator can perform pressure relief work in time to avoid the problem of pressure exceeding the load of the device and causing damage to the internal device of the device.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order 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 thereby design various embodiments with various modifications suitable for specific uses.

[0026] Example 1, please refer to Figure 1-Figure 4The present invention provides a technical solution: a gas separation adsorption tower, comprising a tower body component 1, the bottom of the tower body component 1 is fixedly connected to a support suspension 2; the tower body component 1 comprises a metal shell 11, the top of the metal shell 11 is sleeved with an openable top cover 12 through an opening, a gas transmission pipe 13 is fixedly connected to the axis of the inner cavity of the openable top cover 12, separation components 3 are evenly arranged at the axis of the inner wall of the metal shell 11, an exhaust component 5 is arranged at the axis of the bottom of the inner wall of the metal shell 11, and a gas detection component 4 is arranged at the bottom of the inner wall of the metal 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, the inner wall of the single-side cover plate 31 is rotatably connected to the docking side shell 32 through a guide slot, an annular accommodating shell 33 is evenly arranged at the axis of the inner wall of the single-side cover plate 31, and the inner wall of the annular accommodating shell 33 is provided with adsorption particles 34, and the inner cavity of the docking side shell 32 is evenly provided with a shunt flow pipe 35 through a half-cut through-hole, Figure 3 It can be seen that each separation component 3 is formed by the joint assembly of the upper and lower single-sided cover plates 31, the split flow pipe 35 is fixed through the combined half-cut through-hole, and the upper single-sided cover plate 31 is driven by the torsion motor 36 to rotate clockwise;

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

[0029] There are three groups of separation components 3, and the three groups of separation components 3 are connected in sequence to increase the gas separation process. The top of the top branch flow pipe 35 is connected to the inner cavity of the gas delivery pipe 13 through the docking inner plate. The inner cavity of the annular containment shell 33 is uniformly provided with air inlet holes. The outer surface of the reverse wheel 39 is rollingly connected to the lower surface of the bottom single-sided cover plate 31, and the bottom end of the docking bottom plate 37 is plugged into the top of the inner cavity of the docking inner plate. Each separation component 3 has six branch flow pipes 35, and a through-hole is opened at the axis of the inner cavity of the bottom single-sided cover plate 31. The inner cavity of the docking side shell 32 is uniformly provided with uniform grooves, and the inside of the uniform grooves is fixedly connected with filling magnetic blocks. The outer surface of the annular containment shell 33 is fixedly connected to the inner wall of the single-sided cover plate 31.

[0030] After the device is assembled, the raw gas can be directly introduced into the device through the gas supply pipe 13 on the top, and then the gas flows from top to bottom through the three sets of separation components 3 that are interconnected. After being processed by the separation components 3, the produced oxygen will be discharged from the bottom of the support suspension 2 through the exhaust component 5, and then the gas collection work can be carried out.

[0031] Taking the top separation component 3 as an example, after the gas directly enters the interior of the container composed of the upper and lower docking side shells 32 and the single-sided cover plate 31 through the bypass pipe 35, it will pass through the annular containing shell 33 from the outside to the inside under the action of air pressure, and pass through the adsorption particles 34 inside the annular containing shell 33 to perform gas separation work, and then enter the space in the middle of the container, and be discharged downward to the docking inner disk through the opening of the bottom single-sided cover plate 31, and then be diverted to the separation component 3 below, thereby passing through the three groups of separation components 3 in sequence.

[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 containment shell 33 and the internal adsorption particles 34, and the reverse wheel 39 drives the lower single-sided cover plate 31 to rotate counterclockwise. At this time, the annular containment shells 33 connected at the upper and lower sides rotate in the opposite direction, and the docking side shells 32 will slide relative to the single-sided cover plate 31 under the restriction of the bypass pipe 35, so that the whole remains stationary. Therefore, when the high-pressure gas flowing from the outside to the inside passes through the annular containment shell 33, the internal adsorption particles 34 are not only subjected to a more uniform force, but can also deviate from the axial position under the action of the rotational centrifugal force, thereby effectively alleviating the phenomenon that the adsorption particles 34 are always affected by the airflow and deviate to one side.

[0033] When replacing the separation component 3, the openable top cover 12 can be opened, 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 that the single-sided cover plates 31 on both sides can be opened, and the adsorption particles 34 inside the annular containing shell 33 can be replaced and reassembled 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 Figure 1-Figure 8 The present invention provides a technical solution: on the basis of the first embodiment, the gas detection component 4 includes a bottom partition 41, the inner cavity of the bottom partition 41 is evenly provided with filling tube shells 42 through the through-hole, the inner wall of the filling tube shell 42 is fixedly connected with a filter plug 43, the bottom of the filling tube shell 42 is fixedly connected with an oxygen absorption disk 44, the front and rear sides of the inner cavity of the oxygen absorption disk 44 are symmetrically provided with external wires 45, and the side of the external wire 45 away from the oxygen absorption disk 44 is fixedly connected with an indicator light bar 46, the oxygen absorption disk 44 can detect the content of oxygen in the gas passing into it, and the oxygen concentration passing into the oxygen absorption disk 44 is proportional to the brightness of the indicator light bar 46. The outer surface of the bottom partition 41 is fixedly connected to 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 to the inner cavity of the bottom partition 41 through the through-hole, and the end of the external wire 45 away from the oxygen absorption disk 44 extends to the outside of the metal shell 11.

[0035] The exhaust component 5 includes a centralized bottom cover 51, a pressure-sensing component 6 is arranged at the bottom of the inner cavity of the centralized bottom cover 51, an exhaust shaft tube 52 is fixedly connected to the axis center of the bottom of the inner cavity of the centralized bottom cover 51, horizontal slots 53 are evenly arranged at the lower part of the inner cavity of the exhaust shaft tube 52, and segmented hollow tubes 54 are evenly fixed to the inner cavity of the horizontal slots 53, and a sliding plug plate 55 is fixedly connected to one end of the segmented hollow tube 54 away from the horizontal slots 53. Under normal circumstances, the end of the sliding plug plate 55 away from the exhaust shaft tube 52 is located inside the metal shell 11, but when the pressure of the exhaust shaft tube 52 increases, the segmented hollow tube 54 will push the sliding plug plate 55 on the corresponding side, 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. There are six segmented hollow tubes 54. The outer surface of the sliding plug plate 55 is slidably connected to the bottom of the inner wall of the metal shell 11. The end of the sliding plug plate 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 groove.

[0036] The pressure-sensitive component 6 includes a filling ring 61, a spring sleeve 62 is fixedly connected to the lower surface of the filling ring 61, a pressure-bearing collar 63 is fixedly connected to the bottom end of the spring sleeve 62, and the axis of the inner wall of the pressure-bearing collar 63 is fixedly connected to the outer surface of the exhaust shaft pipe 52. The top 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 41, the lower surface of the centralized bottom cover 51 is fixedly connected to the outer surface of the pressure-bearing collar 63 through a fixed baffle, and the lower surface of the filling ring 61 is slidably connected to the upper part of the inner wall of the pressure-bearing collar 63.

[0037] Under the action of air pressure, the separated oxygen will normally only be discharged to the outside through the exhaust component 5. However, when there is a gas leakage problem inside the separation component 3, the oxygen will directly diffuse into the inside of the metal shell 11 and flow from top to bottom under the action of air pressure. At this time, the gas will be filled into the inside of the oxygen absorption disk 44 through the filling tube shell 42, and then the oxygen absorption disk 44 detects the oxygen and feeds back to the indicator light bar 46 through the external wire 45 according to the oxygen concentration. As the oxygen concentration increases, the indicator light bar 46 will also become brighter.

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

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

[0040] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
