TECHNICAL FIELD
[0001] The application belongs to the technical field of rectification equipment, and particularly relates to a fixed bed type rectification device. BACKGROUND
[0002] The fixed bed type rectification device is a device for separating and refining liquid mixtures, which is usually used in chemical engineering, petroleum chemical industry, medicine and food industry. Its working principle is to pass the liquid mixture through the fixed bed filler in the device to separate different components by using the difference in volatility. Solid fillers (such as silica gel, activated carbon, metal mesh, etc.) are used in the device to increase the surface area of gas-liquid contact and improve the separation efficiency. The mixed liquid is heated in the tower, evaporated and rises to react with the condensed liquid, so that the low-boiling-point components are evaporated first and collected, which is suitable for the separation of multi-component liquid mixtures, especially for components with large volatility difference. Compared with the traditional tower type rectification tower, this device can better deal with some liquids with high viscosity or more solid particles, reducing the plugging problem of the device.
[0003] The fixed bed type rectification device is a very common rectification device on the market. Compared with the conventional structure of the rectification tower, it has the advantages of small volume and high mass transfer efficiency. The gas-liquid two-phase can efficiently transfer heat and mass in the device. There are many different types of fixed bed type rectification devices on the market. The internal structure of the existing device is too simple in actual use. The internal filler (such as Pall ring) is filled in a free bulk manner, which makes the bulk filler in the filler bed prone to position deviation or random shaking during high-speed operation. It cannot effectively guide the gas-liquid to refract and collide multiple times in the filler layer, resulting in limited gas-liquid contact opportunity, and the mass transfer process cannot be maximized, thereby affecting the stability and uniformity of the mass transfer process. At the same time, the traditional liquid supply and gas supply structure design is not reasonable, which leads to uneven distribution of gas-liquid two-phase into the mass transfer area, affecting the mass transfer effect, and incomplete gas-liquid separation is easy to interfere with each other. SUMMARY
[0004] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art and provide a fixed bed type rectification device.

[0009] Further, the sealing tank body comprises a lower tank body located on one side of the top of the support platform, an upper tank body fixedly installed on the top of the lower tank body, and a tank cover fixedly installed on the top of the upper tank body. The lower tank body and the upper tank body, and the upper tank body and the tank cover are fixed through a plurality of fixing bolts. An exhaust port is formed on one side of the top of the tank cover. A liquid discharge port penetrating through the support platform is arranged on one side of the bottom of the lower tank body. Positioning bearings are installed on the center of the inner surface of the bottom of the lower tank body and the center of the bottom of the tank cover. A plurality of fixed supports are fixedly connected to the outer wall of the lower tank body. The lower tank body is fixed to the top of the support platform through the plurality of fixed supports. A rubber sealing ring is fixedly installed on the inner wall of the upper tank body close to the top.
[0010] Through the above technical scheme, the sealing tank body serves as the main support structure, and its main body is composed of a lower tank body, an upper tank body and a tank cover. The combined structure design is convenient for quick assembly and daily maintenance of the equipment. At the same time, the sealing tank body can rotate and support the rotating assembly. During the operation of the equipment, the gas discharged from the top of the rotating assembly enters the upper space of the upper tank body, and then is discharged outward through the exhaust port. The liquid discharged from the bottom of the rotating assembly enters the bottom of the lower tank body, and then is discharged outward through the liquid discharge port.
[0011] Further, the rotating assembly comprises a rotating body located in the sealing tank body. A rotating shaft is fixedly connected to the center of the bottom of the rotating body. A plurality of lower leakage holes are formed in the bottom of the rotating body. An upper cover body is fixedly installed on the top of the rotating body. An upper neck portion is fixedly connected to the center of the top of the upper cover body. A plurality of upper leakage holes are formed in the top of the upper cover body. A plurality of positioning slots are arranged on the inner surface of the bottom of the rotating body. A plurality of positioning sockets are fixedly connected to the bottom of the upper cover body.
[0012] Through the technical scheme, the rotating assembly can rotate at high speed under the driving of the driving mechanism, and the multiple sets of mass transfer assemblies stacked in the rotating assembly can rotate synchronously. In the working process, the gas-liquid two-phase can complete sufficient contact mass transfer in the multiple sets of mass transfer assemblies, the gas after the contact mass transfer can move upward in the rotating body, then enter the upper space of the sealed tank body through the multiple upper leakage holes, and the liquid after the contact mass transfer can flow downward along the inner wall of the rotating body under the action of gravity, then enter the bottom space of the sealed tank body through the multiple lower leakage holes.
[0013] Further, the bottom end of the rotating shaft penetrates the sealed tank body and the support platform, and the top end of the upper neck penetrates the top of the sealed tank body.
[0014] Through the technical scheme, the rotating shaft and the upper neck penetrate the bottom and the top of the sealed tank body respectively, and can rotate under the support of the two positioning bearings, so that the rotating assembly can rotate at high speed stably.
[0015] Further, the mass transfer assembly comprises two rotating discs vertically distributed upward and downward, multiple evenly distributed separation baffles are fixedly connected between the two rotating discs, an annular leakage net is fixedly connected to the circumferential side between the two rotating discs, a circular hole is arranged in the middle of each of the two rotating discs, a filler groove is arranged between the multiple separation baffles, multiple evenly distributed lower sockets are fixedly connected to the circumferential side of the bottom of the lower rotating disc, and multiple evenly distributed upper sockets are fixedly connected to the circumferential side of the top of the upper rotating disc.
[0016] Through the technical scheme, the mass transfer assembly is an important component of the rectifying device and is also a main position of gas-liquid two-phase contact mass transfer, a plurality of evenly distributed separation baffles are arranged between the two rotating discs, so that the internal space can be divided into a plurality of independent packing grooves, the packing grooves are used for filling and placing the required bulk packing, a plurality of mass transfer assemblies are fixed in the internal space of the rotating assembly in a mode of being stacked and inserted through corresponding lower sockets and upper slots, the lowermost mass transfer assembly is inserted into the positioning slot at the bottom of the rotating body, and the uppermost mass transfer assembly is inserted and fixed by the positioning socket at the bottom of the upper cover body, so that the overall fixing and positioning of the plurality of mass transfer assemblies and the rotating assembly are completed, and the plurality of mass transfer assemblies can move synchronously with the rotating assembly; during work, the rotating assembly drives the plurality of mass transfer assemblies to rotate at a high speed synchronously; at the same time, the liquid to be mass transferred is introduced into the internal space of the plurality of mass transfer assemblies through the liquid supply assembly, and the steam is input into the internal space of the plurality of mass transfer assemblies through the gas supply assembly; when the liquid and the steam enter the internal space of the mass transfer assembly at the same time, the mass transfer assembly is in a high-speed rotating state, so that the gas-liquid two phases can fully contact in the packing groove under the action of centrifugal force, so that the mass transfer effect of the gas-liquid two phases is ensured; after the contact mass transfer, a large amount of steam is pre-cooled and liquefied, and is thrown out through the annular leakage net under the action of centrifugal force, and finally flows downward along the inner wall of the rotating body; and part of the gas that is not liquefied is also thrown out through the annular leakage net, and then moves upward along the inner wall of the rotating body.
[0017] Further, the plurality of separation baffles are in an arc-shaped structure, and the plurality of packing grooves are filled with Pall ring bulk packing.
[0018] Through the technical scheme, the separation baffles are designed in an arc-shaped structure, on the one hand, the space between the two rotating discs can be divided into a plurality of independent packing grooves, so as to facilitate filling and placing the Pall ring bulk packing, and the filled Pall ring bulk packing is limited in position to prevent position deviation or random shaking during high-speed rotation; and on the other hand, the structure design can increase the rebound refraction rate of the gas-liquid two phases in the plurality of packing grooves, so as to improve the mass transfer efficiency; in addition, by filling the Pall ring bulk packing, the gas-liquid two phases can repeatedly contact and collide between the plurality of Pall rings in the packing groove when the Pall ring bulk packing rotates at a high speed, so as to ensure that the gas-liquid two phases can fully contact and mass transfer, and the mass transfer efficiency and mass transfer effect are improved.
[0019] Further, the liquid supply assembly comprises a liquid supply pipe penetrating through the rotating assembly and the plurality of mass transfer assemblies, a flange plate is fixedly connected to the top of the liquid supply pipe, a plurality of evenly distributed flow distributors are fixedly connected to the inner wall of the liquid supply pipe, a plurality of evenly distributed flow guide holes are formed in the circumferential side of each flow distributor, a sealing ring is mounted to the inner side of each flow distributor, a plurality of groups of drainage holes and gas pipe insertion holes are formed in the circumferential side of the liquid supply pipe, and a limiting cover 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.
