Description

Technical Field

[0001] The invention belongs to the technical field of gas separation, and in particular relates to a chemical packing tower separation device. Background Art

[0002] A chemical packed tower (also called a packed tower, absorption tower or reaction tower) is a common chemical engineering equipment, which is widely used in processes such as gas-liquid contact, gas absorption, distillation, extraction, and reaction. The packed tower is filled with packing to provide surface area for gas-liquid contact and promote the mass transfer process of substances. Its design and use are usually closely related to the mixing, separation, and reaction process of gas and liquid. The main functions of a chemical packed tower include: gas-liquid contact: the gas rises through the gaps on the packing in the tower, and the liquid is evenly distributed through the packing in the tower to form a liquid film in contact with the gas; separation and absorption: during the contact process between gas and liquid, certain components in the gas can be absorbed or reacted by the liquid, thereby achieving the purpose of separation or concentration. For example, in an acid gas absorption tower, sulfur dioxide gas reacts with water through the packing in the tower to generate sulfuric acid.

[0003] There are many different types of chemical packing towers on the market, but the structures of most chemical packing towers have certain defects. The separation packings inside the existing chemical packing towers all adopt a fixed installation structure. In actual use, the liquid contacts the rising gas in a natural dripping manner. In addition, due to the distribution and dispersion of a large number of packings in the packing tower, although the surface area of ​​gas-liquid contact is increased to a certain extent, the overall contact efficiency is still limited. In order to further ensure the contact efficiency, multiple groups of packing layers are usually installed vertically in the tower body, and liquid redistributors are required between the multiple groups of packing layers. This structural design not only makes the structure inside the packing tower more complicated, but also increases the difficulty of subsequent maintenance. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a chemical packing tower separation device.

[0005] The technical solution adopted to solve the above technical problems is: a chemical packed tower separation device, comprising a packed tower main body, the packed tower main body comprising a tower body, the top and bottom of the tower body are respectively fixedly installed with a top cover and a bottom cover;

[0006] A liquid distribution mechanism is installed near the top of the packed tower body, and an air intake pipe that is connected to the packed tower body is fixedly connected to the bottom of one side of the outer wall of the packed tower body. The air intake pipe is used to transport pressurized flue gas, and the air intake pipe is arranged at a tangent angle to the packed tower body.

[0007] A vertically arranged transmission mechanism is installed in the packing tower body, and a rotation driving mechanism for driving the transmission mechanism to rotate is fixedly installed at the bottom of the inner wall of the packing tower body;

[0008] Two groups of grid supports are fixedly installed on the inner wall of the packing tower body, and two groups of gas-liquid exchange mechanisms for placing ball ring bulk packing are also fixedly installed on the transmission mechanism.

[0009] Furthermore, two inspection openings are provided on one side of the outer wall of the tower body, and inspection covers are fixedly installed on the two inspection openings.

[0010] Through the above technical solution, by providing an inspection port and a corresponding inspection cover, the packing tower can be relatively sealed in the working state, and it is also convenient for operators to carry out daily inspection and maintenance.

[0011] Furthermore, the top cover includes an upper cover body fixed to the top of the packing tower body, and an exhaust port is provided at the center of the top of the upper cover body.

[0012] Through the above technical scheme, when working, the gas to be treated will enter the main body of the packed tower through the air inlet pipe, and the subsequent gas will pass through the rotating drive mechanism, and then be ejected and rise in a ring shape through the rotating drive mechanism, and the gas-liquid two phases will be in reverse contact in the two sets of gas-liquid exchange mechanisms, and closely contact on the surface of the packing for mass transfer, and the gas after absorption treatment will continue to move upward, and finally be discharged outward through the exhaust port on the top of the upper cover body.

[0013] Furthermore, the bottom cover comprises a lower cover body fixed to the bottom of the packing tower body, and a water outlet is provided at the center of the bottom of the lower cover body.

[0014] Through the above technical solution, during the working process, the liquid after absorbing the gas will fall naturally, be collected in the lower cover body, and finally be discharged from the water outlet at the bottom of the lower cover body.

[0015] Furthermore, the liquid distribution mechanism includes a water inlet pipe that passes through the tower body, a distributor is fixedly connected to the bottom of one end of the water inlet pipe, multiple diversion pipes are fixedly connected to both sides of the distributor, and multiple diversion holes are opened at the bottom of the distributor and the multiple diversion pipes.

[0016] Through the above technical scheme, the liquid distribution mechanism is mainly used for uniform distribution of liquid. When working, the liquid will be sent to the top of the tower through the water inlet pipe, and then the liquid will enter the inside of the distributor. Both sides of the distributor are connected with multiple diversion pipes that pass through it. After the liquid enters the diversion pipe, it will naturally fall through the multiple diversion holes at the bottom, so that the liquid can drip evenly onto the gas-liquid exchange mechanism directly below the liquid distribution mechanism, thereby achieving the purpose of uniform liquid distribution.

[0017] Furthermore, the transmission mechanism includes two rotating brackets fixed to the bottom and top of the inner wall of the tower body, and a transmission shaft is rotatably connected between the two rotating brackets.

[0018] Through the above technical solution, the transmission mechanism is mainly used for connecting and linking the rotary drive mechanism and the two groups of gas-liquid exchange mechanisms. When the rotating component of the rotary drive mechanism rotates, the two groups of gas-liquid exchange mechanisms fixed thereto can be driven to rotate through the transmission shaft.

[0019] Furthermore, the rotating drive mechanism includes a lower annular guide rail and an upper annular guide rail fixed to the bottom of the inner wall of the tower body, an annular channel is provided between the lower annular guide rail and the upper annular guide rail, the bottom of the inner wall of the upper annular guide rail is fixedly connected with a guide cover, the top of the upper annular guide rail is provided with an air guide hole on the side close to the air inlet pipe, the top of the upper annular guide rail is fixedly connected with an annular air guide cover, a plurality of evenly distributed air outlet holes are provided on the inner inclined panel of the annular air guide cover, and the plurality of air outlet holes can be arranged in an inwardly inclined downward structure, a fixing ring is provided between the lower annular guide rail and the upper annular guide rail, a plurality of evenly distributed blades are fixedly connected to the outer side of the fixing ring, a plurality of connecting rods are fixedly connected to the inner side of the fixing ring, and a fixing sleeve is fixedly connected between the plurality of connecting rods.

[0020] Through the above technical scheme, when working, when the pressurized gas transported by the air intake pipe passes through the lower annular guide rail and the upper annular guide rail, it will push the multiple blades to rotate, and then drive the rotating assembly composed of a fixed ring, multiple blades, multiple connecting rods and a fixed sleeve to rotate, and then the fixed sleeve can further drive the transmission shaft connected thereto to rotate synchronously. During the rotation of the multiple blades, the gas located between the multiple blades will also move synchronously with them. When it moves to the position of the air guide hole, the gas will enter the annular air guide cover through the air guide hole, and finally be ejected through the multiple air outlet holes on the inner side of the annular air guide cover, thereby achieving the purpose of uniform dispersion of the input gas, so that better gas-liquid contact can be achieved with the falling liquid. At this time, some components in the gas can be absorbed or reacted by the liquid to achieve the purpose of separation, thereby achieving a better contact mass transfer effect, and also improving the overall separation efficiency.

[0021] Furthermore, the air inlet hole of the air inlet duct is located between the lower annular guide rail and the upper annular guide rail, and the transmission shaft passes through and is fixed to the inner wall of the fixing sleeve.

[0022] Through the above technical solution, the gas input through the air intake pipe can accurately enter the area between the lower annular guide rail and the upper annular guide rail to ensure the stability of the pressure, thereby further promoting the rotation of the blades between the lower annular guide rail and the upper annular guide rail.

[0023] Furthermore, the grid support comprises an annular support fixed to the inner wall of the tower body, and a supporting grid is fixedly mounted on the top of the annular support.

[0024] Through the above technical scheme, the grid support can be used to further disperse the rising gas or falling liquid on the one hand. At the same time, since the annular support is fixed to the inner wall of the tower body and the supporting grid is fixed to the top of the annular support, it can play a certain safety protection role for the gas-liquid exchange mechanism on its top, preventing the gas-liquid exchange mechanism from suddenly falling in the event of a fault or manual maintenance, thereby further improving the overall safety of the equipment.

[0025] Furthermore, the gas-liquid exchange mechanism includes a rotating bearing fixedly mounted on the inner wall of the tower body, a fixed grid fixedly mounted on the inner ring of the rotating bearing, the fixed grid fixed on the transmission shaft, a fixed frame fixedly connected to the top of the fixed grid, a plurality of evenly distributed strip holes are opened on the fixed frame, and a detachable grid is movably mounted on the top of the fixed frame.

[0026] Through the above technical scheme, the rotating bearing is mainly used for the rotating support of the fixed grid and the fixed frame, so that the fixed grid and the fixed frame can rotate with the transmission shaft. In addition, the fixed frame is filled with a large number of irregularly distributed ball ring bulk fillers. Therefore, when liquid drips into the fixed frame, a large amount of liquid will be evenly distributed on the outer surface of each ball ring bulk filler and naturally flow downward under the action of gravity, thereby further increasing the distribution area of ​​the liquid. When the rising gas enters the interior of the fixed frame, the gas-liquid two phases can be in more sufficient reverse contact; more importantly, under the rotational drive of the transmission shaft, the entire gas-liquid exchange mechanism will also rotate synchronously with the transmission shaft. During the rotation process, the gas-liquid exchange mechanism can enable the gas-liquid two phases to achieve more sufficient reverse contact, further improving the overall contact mass transfer effect.

[0027] The beneficial effects of the present invention are as follows: (1) The present invention designs a rotary drive mechanism, a transmission mechanism and a gas-liquid exchange mechanism. During the rotation process of the gas-liquid exchange mechanism, the gas-liquid two phases can achieve more sufficient reverse contact, thereby further improving the overall contact mass transfer effect; (2) The present invention designs a rotary drive mechanism, which can drive the transmission shaft and the two groups of gas-liquid exchange mechanisms to rotate synchronously through the rotating assembly. At the same time, when the gas enters the annular gas guide cover through the gas guide hole, it can be sprayed out through the multiple gas outlet holes on the inner side of the annular gas guide cover, thereby achieving the purpose of uniform dispersion of the input gas, so that better gas-liquid contact can be achieved with the falling liquid, so that certain components in the gas can be absorbed or reacted by the liquid to achieve the purpose of separation, thereby achieving better contact mass transfer effect, and also improving the overall separation efficiency; (3) The present invention designs a grid support, which can be used for further dispersion of rising gas or falling liquid, and can also play a certain safety protection role on the gas-liquid exchange mechanism on its top, preventing the gas-liquid exchange mechanism from suddenly falling in the event of a failure or manual maintenance, thereby further improving the overall safety of the equipment.

DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0046] like Figure 1-Figure 16 As shown, a chemical packed tower separation device of the present embodiment includes a packed tower main body 1, and the packed tower main body 1 includes a tower body 101. Two inspection ports 102 are provided on one side of the outer wall of the tower body 101, and inspection covers 103 are fixedly installed on the two inspection ports 102. By providing the inspection ports 102 and the corresponding inspection covers 103, the relative sealing of the packed tower in the working state can be achieved, and it is also convenient for operators to carry out daily inspection and maintenance.

[0047] This embodiment further refers to Figure 1-Figure 3 The top and bottom of the tower body 101 are respectively fixedly installed with a top cover 2 and a bottom cover 3; the top cover 2 includes an upper cover body 201 fixed to the top of the packed tower body 1, and an exhaust port 202 is provided at the top center of the upper cover body 201. During operation, the gas to be treated will enter the packed tower body 1 through the air inlet pipe 5, and the subsequent gas will pass through the rotary drive mechanism 7, and then be ejected in a ring shape and rise through the rotary drive mechanism 7. The gas-liquid two phases will be in reverse contact in the two sets of gas-liquid exchange mechanisms 9, and will be in close contact on the surface of the packing for mass transfer. The gas after absorption continues to move upward, and is finally discharged outward through the exhaust port 202 at the top of the upper cover body 201.

[0048] refer to Figure 1-Figure 3 The bottom cover 3 includes a lower cover body 301 fixed to the bottom of the packing tower body 1. A water outlet 302 is provided at the bottom center of the lower cover body 301. During operation, the liquid after absorbing the gas will naturally fall down and be collected in the lower cover body 301, and finally be discharged from the water outlet 302 at the bottom of the lower cover body 301.

[0049] Regarding the liquid distribution mechanism 4, refer to Figure 8 A liquid distribution mechanism 4 is installed near the top of the packed tower body 1. The liquid distribution mechanism 4 includes an inlet pipe 401 that runs through the tower body 101. A distributor 402 is fixedly connected to the bottom of one end of the inlet pipe 401. Multiple diversion pipes 403 are fixedly connected on both sides of the distributor 402. Multiple diversion holes 404 are provided at the bottom of the distributor 402 and the multiple diversion pipes 403. The liquid distribution mechanism 4 is mainly used for uniform distribution of liquid. When working, the liquid will be sent to the top of the tower through the inlet pipe 401, and then the liquid will enter the inside of the distributor 402. Multiple diversion pipes 403 that are connected to the distributor 402 are connected on both sides. After the liquid enters the diversion pipe 403, it will naturally fall through the multiple diversion holes 404 at the bottom, so that the liquid can evenly drip onto the gas-liquid exchange mechanism 9 directly below the liquid distribution mechanism 4, thereby achieving the purpose of uniform liquid distribution.

[0050] Regarding the intake duct 5, refer to Figure 2-Figure 4 An air intake pipe 5 which is in communication with the packing tower body 1 is fixedly connected to the bottom of one side of the outer wall of the packing tower body 1. The air intake pipe 5 is used to transport pressurized flue gas, and the air intake pipe 5 is arranged at a tangent angle to the packing tower body 1, so that the pressurized flue gas input by the air intake pipe 5 can drive the rotating component in the rotating drive mechanism 7 to rotate.

[0051] Regarding the transmission mechanism 6, refer to Figure 5-Figure 7A vertically arranged transmission mechanism 6 is installed in the packing tower body 1. The transmission mechanism 6 includes two rotating brackets 601 fixed at the bottom and top of the inner wall of the tower body 101. A transmission shaft 602 is rotatably connected between the two rotating brackets 601. The transmission mechanism 6 is mainly used for connecting and linking the rotating drive mechanism 7 with the two groups of gas-liquid exchange mechanisms 9. When the rotating component of the rotating drive mechanism 7 rotates, the two groups of gas-liquid exchange mechanisms 9 fixed thereto can be driven to rotate through the transmission shaft 602.

[0052] Regarding the rotation drive mechanism 7, refer to Figure 1-Figure 15 A rotating drive mechanism 7 for driving the transmission mechanism 6 to rotate is fixedly installed at the bottom of the inner wall of the filling tower body 1; the rotating drive mechanism 7 includes a lower annular guide rail 701 and an upper annular guide rail 702 fixed to the bottom of the inner wall of the tower body 101, an annular channel 703 is provided between the lower annular guide rail 701 and the upper annular guide rail 702, a guide cover 704 is fixedly connected to the bottom of the inner wall of the upper annular guide rail 702, an air guide hole 705 is opened on the top of the upper annular guide rail 702 near the air inlet pipe 5, and the upper annular guide rail The top of the annular air guide 702 is fixedly connected to an annular air guide cover 706, and a plurality of evenly distributed air outlet holes 707 are opened on the inner inclined panel of the annular air guide cover 706, and the plurality of air outlet holes 707 can be arranged in an inwardly inclined downward structure. A fixing ring 708 is provided between the lower annular guide rail 701 and the upper annular guide rail 702, and a plurality of evenly distributed blades 709 are fixedly connected to the outer side of the fixing ring 708, and a plurality of connecting rods 710 are fixedly connected to the inner side of the fixing ring 708, and a plurality of connecting rods 710 are fixedly connected to each other. When the fixed sleeve 711 is working, when the pressurized gas transported by the air inlet pipe 5 passes through the lower annular guide rail 701 and the upper annular guide rail 702, it will push the multiple blades 709 to rotate, and then drive the rotating assembly composed of the fixed ring 708, the multiple blades 709, the multiple connecting rods 710 and the fixed sleeve 711 to rotate, and then the fixed sleeve 711 can further drive the transmission shaft 602 connected thereto to rotate synchronously. During the rotation of the multiple blades 709, the gas located between the multiple blades 709 will also move synchronously with it. When it moves to the position of the air guide hole 705, the gas will enter the annular air guide cover 706 through the air guide hole 705, and finally be ejected through the multiple air outlet holes 707 on the inner side of the annular air guide cover 706, thereby achieving the purpose of uniform dispersion of the input gas, so that better gas-liquid contact can be achieved with the falling liquid. At this time, some components in the gas can be absorbed or reacted by the liquid to achieve the purpose of separation, thereby achieving a better contact mass transfer effect, and also improving the overall separation efficiency.

[0053] Furthermore, in this embodiment, the air inlet hole of the air inlet pipe 5 is located between the lower annular guide rail 701 and the upper annular guide rail 702, and the transmission shaft 602 passes through and is fixed to the inner wall of the fixed sleeve 711, so that the gas input through the air inlet pipe 5 can accurately enter the area between the lower annular guide rail 701 and the upper annular guide rail 702 to ensure the stability of the pressure, thereby further promoting the rotation of the blades 709 between the lower annular guide rail 701 and the upper annular guide rail 702.

[0054] For grille support 8, refer to Figure 5-Figure 7 Two groups of grid supports 8 are fixedly installed on the inner wall of the packing tower body 1. The grid support 8 includes an annular support 801 fixed to the inner wall of the tower body 101. A supporting grid 802 is fixedly installed on the top of the annular support 801. The grid support 8 can be used for further dispersion of rising gas or falling liquid. At the same time, since the annular support 801 is fixed to the inner wall of the tower body 101 and the supporting grid 802 is fixed to the top of the annular support 801, it can play a certain safety protection role on the gas-liquid exchange mechanism 9 on the top, preventing the gas-liquid exchange mechanism 9 from suddenly falling in the event of a failure or manual maintenance, thereby further improving the overall safety of the equipment.

[0055] Regarding the gas-liquid exchange mechanism 9, refer to Figure 5-Figure 10 The transmission mechanism 6 is also fixedly mounted with two groups of gas-liquid exchange mechanisms 9 for placing ball ring bulk fillers 10. The gas-liquid exchange mechanism 9 includes a rotating bearing 901 fixedly mounted on the inner wall of the tower body 101. A fixed grid 902 is fixedly mounted on the inner ring of the rotating bearing 901. The fixed grid 902 is fixed on the transmission shaft 602. A fixed frame 903 is fixedly connected to the top of the fixed grid 902. A plurality of evenly distributed strip holes 904 are opened on the fixed frame 903. A detachable grid 905 is movably mounted on the top of the fixed frame 903. The rotating bearing 901 is mainly used for the rotation support of the fixed grid 902 and the fixed frame 903, so that the fixed grid 902 and the fixed frame 903 can be rotated. 03 can rotate along with the transmission shaft 602. In addition, the fixed frame 903 is filled with a large number of irregularly distributed ball ring bulk fillers 10. Therefore, when liquid drips into the fixed frame 903, a large amount of liquid will be evenly distributed on the outer surface of each ball ring bulk filler 10, and naturally flow downward under the action of gravity, thereby further increasing the distribution area of ​​the liquid. When the rising gas enters the interior of the fixed frame 903, the gas-liquid two phases can be in more sufficient reverse contact. The detachable grid 905 movably installed on the top of the fixed frame 903 can limit and fix the internal bulk filler 10 to prevent the gas-liquid exchange mechanism 9 from scattering during rotation.

[0056] Furthermore, and more importantly, in this embodiment, under the rotational drive of the transmission shaft 602, the entire gas-liquid exchange mechanism 9 will also rotate synchronously with the transmission shaft 602. During the rotation process, the gas-liquid exchange mechanism 9 can enable the gas-liquid two phases to achieve more sufficient reverse contact, thereby further improving the overall contact mass transfer effect.

[0057] The working principle of this embodiment is as follows. When working, the pressurized gas will be transported to the packing tower body 1 at a tangential angle through the air inlet pipe 5, which will drive the multiple blades 709 to rotate, and then drive the rotating assembly composed of the fixed ring 708, the multiple blades 709, the multiple connecting rods 710 and the fixed sleeve 711 to rotate, and then the fixed sleeve 711 can further drive the transmission shaft 602 and the two sets of gas-liquid exchange mechanisms 9 connected thereto to rotate synchronously;

[0058] When the gas between the multiple blades 709 moves to the position of the gas guide hole 705, the gas will enter the annular gas guide cover 706 through the gas guide hole 705, and finally be ejected through the multiple gas outlet holes 707 on the inner side of the annular gas guide cover 706, thereby achieving uniform dispersion of the input gas, and the ejected gas will move upward;

[0059] At the same time, the liquid is sent to the top of the tower through the water inlet pipe 401, and then the liquid enters the distributor 402. Both sides of the distributor 402 are connected with multiple diversion pipes 403 that penetrate therethrough. After the liquid enters the diversion pipe 403, it naturally falls through multiple diversion holes 404 at the bottom, so that the liquid can evenly drip onto the gas-liquid exchange mechanism 9 directly below the liquid distribution mechanism 4.

[0060] The fixed frame 903 is filled with a large number of irregularly distributed ball ring bulk fillers 10. Therefore, when liquid drips into the fixed frame 903, a large amount of liquid will be evenly distributed on the outer surface of each ball ring bulk filler 10 and naturally flow downward under the action of gravity. When the rising gas enters the fixed frame 903, the gas-liquid two phases can be in relatively sufficient reverse contact.

[0061] In addition, under the rotational drive of the transmission shaft 602, the entire gas-liquid exchange mechanism 9 will also rotate synchronously with the transmission shaft 602. During the rotation process, the gas-liquid exchange mechanism 9 also enables the gas-liquid two phases to achieve more sufficient reverse contact. The liquid after absorbing the gas will naturally fall and be collected in the lower cover body 301, and finally be discharged from the water outlet 302 at the bottom of the lower cover body 301, and the gas after absorption continues to move upward, and finally is discharged outward through the exhaust port 202 at the top of the upper cover body 201.
