Description

Technical Field

[0001] This invention belongs to the technical field of distillation equipment, specifically relating to a fixed-bed distillation apparatus. Background Technology

[0002] A bed distillation unit is a device used for separating and refining liquid mixtures, commonly used in chemical engineering, petrochemical, pharmaceutical, and food industries. Its working principle involves passing the liquid mixture through a fixed-bed packing system, separating the components based on their differences in volatility. Solid packing materials (such as silica gel, activated carbon, and metal mesh) are used to increase the surface area for gas-liquid contact, improving separation efficiency. The mixed liquid is heated inside the column, evaporates, rises, and reacts with the condensed liquid, causing the lower-boiling-point components to evaporate first and be collected. It is suitable for separating multi-component liquid mixtures, especially those with significant differences in volatility. Compared to traditional column distillation columns, this device is better able to handle liquids with high viscosity or a high concentration of solid particles, reducing equipment clogging issues.

[0003] Bed distillation units are a common type of distillation equipment on the market. Compared with conventional distillation columns, bed distillation units have advantages such as small size and high mass transfer efficiency. The gas and liquid phases can carry out efficient heat and mass transfer inside the unit. Currently, there are various types of bed distillation units on the market. In actual use, the internal structure design of existing units is too simple. The internal packing (such as Pall rings) is filled in a free and loose manner. This makes it easy for the loose packing inside the packed bed to shift position or sway randomly when the bed is running at high speed. This fails to effectively guide the gas and liquid to refract and collide multiple times within the packing layer, resulting in limited gas-liquid contact opportunities. The mass transfer process is not maximized, which in turn affects the stability and uniformity of the mass transfer process. At the same time, the traditional liquid and gas supply structure design is not reasonable enough, resulting in uneven distribution of the gas and liquid phases when they enter the mass transfer zone, affecting the mass transfer effect. Moreover, the gas-liquid separation is incomplete and prone to mutual interference. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a fixed-bed distillation apparatus.

[0005] The technical solution adopted to solve the above technical problems is: a fixed-bed distillation device, including a support platform, a sealed tank is fixedly installed on one side of the top of the support platform, and a rotating component is rotatably connected inside the sealed tank;

[0006] Multiple sets of uniformly distributed mass transfer components are stacked vertically inside the rotating assembly, and a liquid supply component runs through the rotating assembly.

[0007] The top of the liquid supply assembly is connected to a liquid delivery pipe, which is used to transport liquid. The liquid then enters the interior of multiple mass transfer assemblies through the liquid supply assembly. A gas delivery assembly is installed inside the liquid supply assembly. Gas is input through the bottom of the gas delivery assembly and enters the interior of multiple mass transfer assemblies.

[0008] A drive mechanism for driving the rotating components to rotate is installed on the other side of the top of the support platform.

[0009] Furthermore, the sealed tank includes a lower tank located on one side of the top of the support platform. An upper tank is fixedly installed on the top of the lower tank, and a tank cover is fixedly installed on the top of the upper tank. The lower tank and the upper tank, as well as the upper tank and the tank cover, are fixed together by multiple fixing bolts. An exhaust port is provided on one side of the top of the tank cover, and a drain port penetrating the support platform is provided on one side of the bottom of the lower tank. Positioning bearings are installed at the center of the bottom inner surface of the lower tank and the center of the bottom of the tank cover. Multiple fixing supports are fixedly connected to the periphery of the outer wall of the lower tank, and the lower tank is fixed to the top of the support platform by the multiple fixing supports. A rubber sealing ring is fixedly installed on the inner wall of the upper tank near the top.

[0010] Through the above technical solution, the sealed tank serves as the main support structure, consisting of a lower tank, an upper tank, and a tank cover. Its modular structural design facilitates rapid assembly and routine maintenance of the equipment. Meanwhile, the sealed tank provides rotational support and positioning for the internal rotating components. During operation, the gas discharged from the top of the rotating components enters the upper space of the upper tank and is then discharged outward through the exhaust port; the liquid discharged from the bottom of the rotating components enters the bottom of the lower tank and is then discharged outward through the drain port.

[0011] Furthermore, the rotating assembly includes a rotating body located inside the sealed container. A rotating shaft is fixedly connected to the center of the bottom of the rotating body. Multiple through-holes are provided on the periphery of the bottom of the rotating body. An upper cover is fixedly installed on the top of the rotating body. An upper neck is fixedly connected to the center of the top of the upper cover. Multiple evenly distributed upper holes are provided on the periphery of the top of the upper cover. Multiple evenly distributed positioning slots are provided on the periphery of the inner surface of the bottom of the rotating body. Multiple evenly distributed positioning sockets are fixedly connected to the periphery of the bottom of the upper cover.

[0012] Through the above technical solution, the rotating component can rotate at high speed under the drive of the drive mechanism. The multiple sets of mass transfer components stacked inside it can rotate synchronously with it. During the operation, the gas and liquid phases will complete full contact mass transfer in the multiple sets of mass transfer components. After the contact mass transfer is completed, the gas will move upward in the rotating body and then enter the upper space of the sealed tank through multiple upper leakage holes. The liquid after the contact mass transfer is completed will flow downward along the inner wall of the rotating body under the action of gravity and then enter the bottom space of the sealed tank through multiple lower leakage holes.

[0013] Furthermore, the bottom end of the rotating shaft penetrates through the sealed tank and the support platform, and the top end of the upper neck penetrates through the top of the sealed tank.

[0014] Through the above technical solution, the rotating shaft and the upper neck pass through the bottom and top of the sealed tank respectively, and can rotate under the support of two positioning bearings, thereby ensuring that the rotating component can rotate stably at high speed.

[0015] Furthermore, the mass transfer assembly includes two rotating disks vertically distributed vertically, with multiple evenly distributed partition baffles fixedly connected between the two rotating disks, an annular mesh fixedly connected to the periphery between the two rotating disks, a circular hole in the center of each of the two rotating disks, a filling groove between the multiple partition baffles, multiple evenly distributed lower sockets fixedly connected to the bottom periphery of the lower rotating disk, and multiple evenly distributed upper slots fixedly connected to the top periphery of the upper rotating disk.

[0016] Through the above technical solution, the mass transfer component, as an important part of the distillation unit and the main location for gas-liquid two-phase contact mass transfer, is divided into multiple independent packing tanks by multiple evenly distributed baffles between the two rotating disks. These packing tanks are used to fill and hold the required bulk packing. Multiple sets of mass transfer components are fixed inside the rotating assembly by stacking and inserting corresponding lower sockets and upper slots. The lowest set of mass transfer components is inserted into the positioning slot at the bottom of the rotating body, while the highest set is fixed by the positioning socket at the bottom of the upper cover. This completes the overall fixation and positioning of multiple sets of mass transfer components with the rotating assembly, enabling the multiple sets of mass transfer components to interact with the rotating body. The rotating components move synchronously. During operation, the rotating components drive multiple sets of mass transfer components to rotate synchronously at high speed. At the same time, the liquid to be transferred is introduced into the multiple sets of mass transfer components through the liquid supply component, while the steam is introduced into the multiple sets of mass transfer components through the gas supply component. When the liquid and steam enter the mass transfer components at the same time, the high-speed rotation of the mass transfer components allows the gas and liquid phases to fully contact each other in the packing tank under the action of centrifugal force, thus ensuring the mass transfer effect of the gas and liquid phases. After contact mass transfer, a large amount of steam is pre-cooled and liquefied, and is thrown out through the annular mesh under the action of centrifugal force, and finally flows downward along the inner wall of the rotating body. Some unliquefied gas is also thrown out through the annular mesh and then moves upward along the inner wall of the rotating body.

[0017] Furthermore, all of the aforementioned partition baffles are designed with an arc shape, and all of the multiple packing grooves are filled with Pall ring bulk packing.

[0018] Through the above technical solution, by designing the partition baffle into an arc-shaped structure, the space between the two rotating disks can be divided into multiple independent packing slots. This facilitates the filling and placement of Pall ring bulk packing and also limits the position of the filled Pall ring bulk packing, preventing it from shifting or randomly shaking during high-speed rotation. At the same time, its structural design can also increase the refractive index of the gas and liquid phases in multiple packing slots, thereby improving mass transfer efficiency. In addition, by filling with Pall ring bulk packing, when it rotates at high speed, the gas and liquid phases can repeatedly contact and collide with each other in the multiple Pall rings in the packing slot, thus ensuring that the gas and liquid phases can fully contact and transfer mass, thereby improving mass transfer efficiency and mass transfer effect.

[0019] Furthermore, the liquid supply assembly includes a liquid supply pipe that passes through the rotating assembly and multiple sets of mass transfer assemblies. A flange is fixedly connected to the top of the liquid supply pipe, and multiple evenly distributed diverters are fixedly connected to the inner wall of the liquid supply pipe. Multiple evenly distributed guide holes are opened on the periphery of each of the multiple diverters, and a sealing ring is installed on the inner side of each diverter. Multiple sets of drainage holes and tracheal insertion holes are opened on the periphery of the liquid supply pipe, and a limit cap is threadedly connected to the bottom end of the liquid supply pipe.

[0020] Through the above technical solution, the liquid supply component is mainly used for liquid transportation. During operation, the liquid enters the liquid supply pipe through the liquid delivery pipe. After the liquid enters the liquid supply pipe, due to the multiple evenly distributed diverters fixedly connected to the inner wall of the liquid supply pipe, the liquid will flow from top to bottom under the action of gravity. When the liquid passes through the first diverter, some of the liquid will flow out through multiple drainage holes at the corresponding position, and then enter the mass transfer component at the corresponding position. At the same time, most of the liquid will continue to flow downward through multiple guide holes on the diverter. The diverters below will work in the same way. No guide holes are opened on the diverter at the bottom to prevent it from leaking from the bottom of the liquid supply pipe.

[0021] Furthermore, the flange is fixed to the top of the sealed tank, and each set of drainage holes and tracheal insertion holes are located above and below the corresponding distributor, respectively.

[0022] The above technical solution uses a diverter to separate and isolate the drainage hole and the endotracheal inlet, thereby achieving effective gas-liquid separation and forming independent liquid and gas supply channels.

[0023] Furthermore, the gas delivery assembly includes a gas delivery pipe that passes through multiple distributors. The top end of the gas delivery pipe is provided with a hemisphere. The gas delivery pipe has multiple sets of evenly distributed threaded connection holes. Each threaded connection hole is threaded with a gas guide pipe, and each gas guide pipe passes through a corresponding gas pipe insertion hole.

[0024] Through the above technical solution, the gas conveying component is mainly used for gas conveying. During operation, the gas is input through the bottom of the gas conveying pipe. At this time, the gas will move from bottom to top along the gas conveying pipe. Multiple sets of gas guide tubes are threaded on the gas conveying pipe, and each gas guide tube passes through the corresponding gas pipe insertion hole, so that the gas in the gas conveying pipe can be introduced into the corresponding mass transfer component through multiple sets of gas guide tubes.

[0025] Furthermore, the drive mechanism includes a drive motor fixedly installed on the other side of the top of the support platform, a first pulley fixedly installed at the output end of the drive motor, a second pulley fixedly installed at the bottom end of the rotating shaft, and a transmission belt installed between the first pulley and the second pulley.

[0026] With the above technical solution, the drive mechanism serves as the main power source. When it is working, the drive motor drives the first pulley to rotate synchronously through the output shaft, and then drives the second pulley and the entire rotating assembly to rotate synchronously through the transmission belt. This allows multiple mass transfer components to rotate synchronously with it. Therefore, when liquid and gas enter the interior of the high-speed rotating mass transfer component, the gas and liquid phases will come into full contact within the mass transfer component, thus ensuring the mass transfer effect and efficiency.

[0027] The beneficial effects of the present invention are as follows: (1) By designing the rotating component and the mass transfer component, when the rotating component rotates at high speed, the gas and liquid phases can repeatedly contact and collide between multiple Pall rings in the packing tank, thereby ensuring that the gas and liquid phases can fully contact and transfer mass, thus improving the mass transfer efficiency and mass transfer effect; (2) By designing the partition baffle into an arc structure, the present invention can divide the space between the two rotating disks into multiple independent packing tanks, so as to facilitate the filling and placement of Pall ring bulk packing, and to limit the filling of Pall ring bulk packing, preventing it from shifting position or randomly shaking during high-speed rotation. At the same time, its structural design can also increase the rebound refractive index of the gas and liquid phases in multiple packing tanks, thereby improving the mass transfer efficiency; (3) By designing the combined liquid supply component and gas supply component, the present invention not only has a simpler and more compact structural design, but also can achieve effective gas-liquid separation, thereby forming independent liquid supply and gas supply channels, ensuring that the gas and liquid phases can be uniformly input into the mass transfer component, thereby completing efficient mass transfer.

[0047] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0048] like Figures 1-18As shown, a fixed-bed distillation apparatus of this embodiment includes a support platform 1. A sealed tank 2 is fixedly installed on one side of the top of the support platform 1. The sealed tank 2 includes a lower tank 201 located on one side of the top of the support platform 1. An upper tank 202 is fixedly installed on the top of the lower tank 201. A tank cover 203 is fixedly installed on the top of the upper tank 202. The lower tank 201 and the upper tank 202, and the upper tank 202 and the tank cover 203 are fixed by multiple fixing bolts 204. An exhaust port 205 is provided on one side of the top of the tank cover 203. A drain port 206 penetrating the support platform 1 is provided on one side of the bottom of the lower tank 201. Positioning bearings 207 are installed at the center of the bottom inner surface of the lower tank 201 and the center of the bottom of the tank cover 203. Multiple fixed bearings are fixedly connected to the periphery of the outer wall of the lower tank 201. The lower tank 201 is fixed to the top of the support platform 1 by multiple fixed supports 208. A rubber sealing ring 209 is fixedly installed on the inner wall of the upper tank 202 near the top. The sealed tank 2 serves as the main support structure, and its main body is composed of the lower tank 201, the upper tank 202, and the tank cover 203. Its modular structure design facilitates quick assembly and daily maintenance of the equipment. At the same time, the sealed tank 2 can provide rotational support and positioning for the internal rotating component 3. During the operation of the equipment, the gas discharged from the top of the rotating component 3 will enter the upper space of the upper tank 202 and then be discharged outward through the exhaust port 205; the liquid discharged from the bottom of the rotating component 3 will enter the bottom of the lower tank 201 and then be discharged outward through the drain port 206.

[0049] Regarding rotating component 3, please refer to... Figures 1-10 A rotating assembly 3 is rotatably connected inside the sealed container 2. The rotating assembly 3 includes a rotating body 301 located inside the sealed container 2. A rotating shaft 302 is fixedly connected to the center of the bottom of the rotating body 301. Multiple through-holes 303 are opened on the circumference of the bottom of the rotating body 301. An upper cover 304 is fixedly installed on the top of the rotating body 301. An upper neck 305 is fixedly connected to the center of the top of the upper cover 304. Multiple evenly distributed upper holes 306 are opened on the circumference of the top of the upper cover 304. Multiple evenly distributed positioning slots 307 are provided on the circumference of the inner surface of the bottom of the rotating body 301. The upper cover 304 is fixedly connected to the circumference of the bottom of the upper neck 305. The rotating component 3 is equipped with multiple evenly distributed positioning sockets 308. When it is working, it can rotate at high speed under the drive of the drive mechanism 8. The multiple sets of mass transfer components 4 stacked inside it can rotate synchronously with it. During the operation, the gas and liquid phases will complete full contact mass transfer in the multiple sets of mass transfer components 4. After the contact mass transfer is completed, the gas will move upward in the rotating body 301 and then enter the upper space of the sealed tank 2 through multiple upper leakage holes 306. The liquid after the contact mass transfer is completed will flow downward along the inner wall of the rotating body 301 under the action of gravity and then enter the bottom space of the sealed tank 2 through multiple lower leakage holes 303.

[0050] In this embodiment, the bottom end of the rotating shaft 302 penetrates through the sealed tank 2 and the support platform 1, and the top end of the upper neck 305 penetrates through the top of the sealed tank 2. The rotating shaft 302 and the upper neck 305 penetrate through the bottom and top of the sealed tank 2 respectively, and can rotate under the support of two positioning bearings 207, thereby ensuring that the rotating assembly 3 can rotate stably at high speed.

[0051] Regarding mass transfer component 4, please refer to... Figures 10-18 Multiple sets of uniformly distributed mass transfer components 4 are stacked vertically within the rotating assembly 3. Each mass transfer component 4 includes two vertically distributed rotating disks 401. Multiple uniformly distributed partition plates 402 are fixedly connected between the two rotating disks 401. An annular mesh 403 is fixedly connected to the circumference of the two rotating disks 401. A circular hole 404 is provided in the center of each of the two rotating disks 401. A filling groove 405 is provided between the partition plates 402. Multiple uniformly distributed lower sockets 406 are fixedly connected to the bottom circumference of the lower rotating disk 401. Multiple evenly distributed upper slots 407 are fixedly connected to the top periphery of the square rotating disk 401. The mass transfer assembly 4 is an important component of the distillation unit and also the main location for gas-liquid two-phase contact mass transfer. Multiple evenly distributed partition baffles 402 are provided between the two rotating disks 401, thereby dividing its internal space into multiple independent packing tanks 405. The packing tanks 405 are used to fill and place the required bulk packing. Multiple sets of mass transfer assemblies 4 are fixed inside the rotating assembly 3 by stacking and inserting corresponding lower sockets 406 and upper slots 407. The lowest mass transfer assembly 4 is inserted into the positioning slot 307 at the bottom of the rotating body 301, while the highest mass transfer assembly 4 is fixed by the positioning socket 308 at the bottom of the upper cover 304. This completes the overall fixation and positioning of the multiple mass transfer assemblies 4 and the rotating assembly 3, enabling the multiple mass transfer assemblies 4 to move synchronously with the rotating assembly 3. During operation, the rotating assembly 3 drives the multiple mass transfer assemblies 4 to rotate synchronously at high speed. At the same time, the liquid to be transferred is introduced into the multiple mass transfer assemblies 4 through the liquid supply assembly 5, while the steam is introduced through the gas delivery assembly. 7. The liquid and steam are fed into the mass transfer components 4 respectively. When the liquid and steam enter the mass transfer components 4 at the same time, the mass transfer components 4 are in a high-speed rotation state, so that the gas and liquid phases can fully contact each other in the packing tank 405 under the action of centrifugal force, thereby ensuring the mass transfer effect of the gas and liquid phases. After contact mass transfer, a large amount of steam is pre-cooled and liquefied, and is thrown out through the annular mesh 403 under the action of centrifugal force, and finally flows downward along the inner wall of the rotating body 301. Some unliquefied gas is also thrown out through the annular mesh 403 and then moves upward along the inner wall of the rotating body 301.

[0052] In this embodiment, the multiple partition baffles 402 are all designed with an arc shape, and the multiple packing grooves 405 are filled with Pall ring bulk packing. By designing the partition baffles 402 with an arc shape, on the one hand, the space between the two rotating disks 401 can be divided into multiple independent packing grooves 405 to facilitate the filling and placement of Pall ring bulk packing, and to limit the position of the filled Pall ring bulk packing, preventing it from shifting position or randomly shaking during high-speed rotation. At the same time, its structural design can also increase the refractive index of the gas and liquid phases in the multiple packing grooves 405, thereby improving the mass transfer efficiency. In addition, by filling with Pall ring bulk packing, when it rotates at high speed, the gas and liquid phases can repeatedly contact and collide with each other in the multiple Pall rings in the packing grooves 405, thereby ensuring that the gas and liquid phases can fully contact and transfer mass, thereby improving the mass transfer efficiency and mass transfer effect.

[0053] Regarding liquid supply component 5, please refer to... Figures 7-15 A liquid supply assembly 5 runs through the rotating assembly 3. The liquid supply assembly 5 includes a liquid supply pipe 501 that runs through the rotating assembly 3 and multiple sets of mass transfer assemblies 4. A flange 502 is fixedly connected to the top of the liquid supply pipe 501. Multiple evenly distributed diverters 503 are fixedly connected to the inner wall of the liquid supply pipe 501. Multiple evenly distributed guide holes 504 are opened on the periphery of each diverter 503. A sealing ring 505 is installed on the inner side of each diverter 503. Multiple sets of drainage holes 506 and tracheal insertion holes 507 are opened on the periphery of the liquid supply pipe 501. A limit cap 508 is threadedly connected to the bottom end of the liquid supply pipe 501. The liquid supply assembly 5 is mainly used for liquid transportation. During operation, the liquid will be transported through the liquid supply assembly 5. Pipe 6 enters the liquid supply pipe 501. After the liquid enters the liquid supply pipe 501, because the inner wall of the liquid supply pipe 501 is fixedly connected with multiple evenly distributed diverters 503, the liquid will flow from top to bottom under the action of gravity. When the liquid passes through the first diverter 503, some of the liquid will flow out through multiple drainage holes 506 at the corresponding position, and then enter the mass transfer component 4 at the corresponding position. At the same time, most of the liquid will continue to flow downward through multiple guide holes 504 on the diverter 503. The diverters 503 below will work in the same way. The diverter 503 at the bottom does not have a guide hole 504 to prevent it from leaking from the bottom of the liquid supply pipe 501.

[0054] In this embodiment, the top of the liquid supply pipe 501 is provided with an integrated flange 502. The flange 502 is fixed to the top of the sealed tank 2 by screws, so that the liquid supply component 5 can remain fixed and will not rotate with the rotating component 3 during operation. Each set of drainage holes 506 and tracheal insertion holes 507 are located above and below the corresponding distributor 503, respectively. The distributor 503 separates and isolates the drainage holes 506 and tracheal insertion holes 507, thereby achieving effective gas-liquid separation and forming independent liquid and gas supply channels.

[0055] In this embodiment, the top of the liquid supply component 5 is connected to a liquid delivery pipe 6, which is used to transport liquid. Then the liquid enters the interior of multiple mass transfer components 4 through the liquid supply component 5.

[0056] Regarding gas delivery component 7, please refer to... Figures 7-15 The liquid supply assembly 5 is equipped with a gas delivery assembly 7. Gas is input through the bottom end of the gas delivery assembly 7 and enters the interior of multiple mass transfer assemblies 4. The gas delivery assembly 7 includes a gas delivery pipe 701 that passes through multiple distributors 503. The top end of the gas delivery pipe 701 is provided with a hemisphere 702. Multiple sets of evenly distributed threaded connection holes 703 are opened on the gas delivery pipe 701. Each threaded connection hole 703 is threaded with a gas guide pipe 704, and each gas guide pipe 704 passes through a corresponding gas pipe insertion hole 507. The gas delivery assembly 7 is mainly used for gas delivery. During operation, gas is input through the bottom of the gas delivery pipe 701. At this time, the gas will move from bottom to top along the gas delivery pipe 701. Multiple sets of gas guide pipes 704 are threaded on the gas delivery pipe 701, and each gas guide pipe 704 passes through a corresponding gas pipe insertion hole 507, so that the gas in the gas delivery pipe 701 can be introduced into the corresponding mass transfer assembly 4 through multiple sets of gas guide pipes 704.

[0057] Regarding drive mechanism 8, refer to... Figures 1-3 A drive mechanism 8 for driving the rotating assembly 3 to rotate is installed on the other side of the top of the support platform 1. The drive mechanism 8 includes a drive motor 801 fixedly installed on the other side of the top of the support platform 1. A first pulley 802 is fixedly installed at the output end of the drive motor 801, and a second pulley 803 is fixedly installed at the bottom end of the rotating shaft 302. A transmission belt 804 is installed between the first pulley 802 and the second pulley 803. As the main power source, when the drive mechanism 8 is working, the drive motor 801 will drive the first pulley 802 to rotate synchronously through the output shaft, and then drive the second pulley 803 and the entire rotating assembly 3 to rotate synchronously through the transmission belt 804. This allows multiple sets of mass transfer components 4 to rotate synchronously with it. Therefore, when liquid and gas enter the interior of the high-speed rotating mass transfer component 4, the gas and liquid phases will fully contact each other inside the mass transfer component 4, thereby ensuring the mass transfer effect and mass transfer efficiency.

[0058] The working principle of this embodiment is as follows: During operation, the drive motor 801 drives the second pulley 803 and the entire rotating assembly 3 to rotate synchronously through the transmission belt 804, so that multiple sets of mass transfer components 4 can rotate synchronously with it.

[0059] Meanwhile, the liquid enters the supply pipe 501 through the infusion pipe 6. After the liquid enters the supply pipe 501, the liquid will flow from top to bottom under the action of gravity because the inner wall of the supply pipe 501 is fixedly connected with multiple evenly distributed diverters 503. When the liquid passes through the first diverter 503, some of the liquid will flow out through multiple drainage holes 506 at the corresponding position and enter the mass transfer component 4 at the corresponding position. Most of the liquid will continue to flow downward through multiple guide holes 504 on the diverter 503. The diverters 503 below will also work according to the same process.

[0060] During this process, gas is input through the bottom of the gas supply pipe 701. At this time, the gas will move from bottom to top along the gas supply pipe 701. Multiple sets of gas guide pipes 704 are threaded on the gas supply pipe 701, and each gas guide pipe 704 passes through the corresponding gas pipe insertion hole 507, so that the gas in the gas supply pipe 701 can be introduced into the corresponding mass transfer component 4 through the multiple sets of gas guide pipes 704.

[0061] When liquid and steam enter the mass transfer component 4 simultaneously, the high-speed rotation of the mass transfer component 4 allows the gas and liquid phases to fully contact each other in the packing tank 405 under centrifugal force, thus ensuring the mass transfer effect of the gas and liquid phases. After contact mass transfer, a large amount of steam is pre-cooled and liquefied, and is thrown out through the annular mesh 403 under centrifugal force, eventually flowing downward along the inner wall of the rotating body 301. Some unliquefied gas is also thrown out through the annular mesh 403 and then moves upward along the inner wall of the rotating body 301. The gas discharged from the top of the rotating component 3 enters the upper space of the upper tank 202 and is then discharged outward through the exhaust port 205. The liquid discharged from the bottom of the rotating component 3 enters the bottom of the lower tank 201 and is then discharged outward through the drain port 206.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
