Description

Technical Field

[0001] This invention relates to the field of carbon dioxide gasification technology, specifically to a carbon dioxide gasification device. Background Technology

[0002] As an important industrial gas, carbon dioxide plays an indispensable role in many fields, with a wide range of applications, covering everything from the food industry to chemical production, environmental protection, and medicine.

[0003] An ambient air vaporizer is often used to convert liquid carbon dioxide into gaseous carbon dioxide. An ambient air vaporizer is a heat exchange device that uses natural air convection to heat and vaporize liquid carbon dioxide inside the tube. The ambient air vaporizer is mainly composed of aluminum finned tubes connected at certain intervals. Liquid carbon dioxide is introduced into the finned tubes, and then airflow flows from top to bottom through the finned tubes to heat the liquid carbon dioxide inside the tubes, thereby heating the liquid carbon dioxide into gaseous carbon dioxide and discharging it.

[0004] However, during the conversion of gaseous carbon dioxide, a large amount of heat needs to be absorbed, which leads to a decrease in the ambient temperature and causes frost to form on the surface of the finned tube. Frost can cause uneven stress on the vaporizer, resulting in lateral tension and potentially causing the finned tube to crack. At the same time, frost also affects the heat conduction performance of the vaporizer itself and reduces the vaporization efficiency.

[0005] In view of this, we propose a carbon dioxide gasification device. Summary of the Invention

[0006] The purpose of this invention is to provide a carbon dioxide vaporization device to solve the problem of frost formation on the surface of ambient air vaporizers mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A carbon dioxide vaporization device includes: a frame, a heat exchange channel, a distribution pipe, a motor, a reciprocating assembly, cleaning fins, a rotating assembly, and an exhaust fan blade; the heat exchange channel is fixedly installed on the frame; the heat exchange channel consists of a liquid inlet pipe, an exhaust pipe, and finned tubes, the liquid inlet pipe and the exhaust pipe are respectively installed at both ends of the frame, and multiple sets of finned tubes are linearly arranged between the liquid inlet pipe and the exhaust pipe. During vaporization, liquid carbon dioxide is first introduced into the finned tubes through the liquid inlet pipe, and the liquid carbon dioxide circulates from bottom to top. During the flow of liquid carbon dioxide, the liquid carbon dioxide exchanges heat with the outside air through the finned tubes, thereby causing the liquid carbon dioxide to absorb heat and rise in temperature, and then vaporize into gaseous carbon dioxide. Then, the gaseous carbon dioxide is discharged through the exhaust pipe for collection. A diversion pipe is provided between the liquid inlet pipe and the gas outlet pipe. This diversion pipe is staggered with the finned tubes. The diversion pipe guides a portion of the vaporized carbon dioxide to flow through the bottom of the finned tubes, where it exchanges heat with the air at the bottom, thus preventing condensation and frost formation due to low bottom temperatures. The motor is fixedly mounted on the frame. A reciprocating assembly is located on one side of the motor, and cleaning fins are installed within the reciprocating assembly. The motor drives the cleaning fins to reciprocate, contacting the surface of the finned tubes for defrosting. When vaporizing liquid carbon dioxide, the motor starts, causing the reciprocating assembly to move synchronously. The reciprocating motion of the cleaning fins removes condensate and frost from the bottom of the finned tubes, preventing frost buildup that reduces heat exchange efficiency and affects vaporization. A rotating component is located on one side of the reciprocating assembly, with fan blades mounted on it. These fan blades are rotatably mounted on the frame. When the reciprocating assembly is working, the rotating component drives the exhaust fan blades to rotate unidirectionally, reducing air humidity. The rotating component also drives the exhaust fan blades to rotate, which in turn blows airflow at the bottom, preventing excessive water molecules from forming at the bottom of the finned tubes and thus reducing the likelihood of condensation and frost buildup.

[0008] Preferably, the inlet pipe consists of a gas layer pipe and a liquid layer pipe; a liquid layer pipe is fixedly installed inside the gas layer pipe, and the liquid layer pipe is used to introduce liquid carbon dioxide. The gas layer pipe is connected to the outlet pipe through a diverter pipe. The diverter pipe discharges the gaseous carbon dioxide that has completed heat exchange in the outlet pipe, allowing the gaseous carbon dioxide to pass through the bottom of the finned tube and exchange heat with the air at the bottom of the finned tube. This avoids the formation of condensate and frost on the surface of the finned tube due to the low bottom temperature. Furthermore, introducing gaseous carbon dioxide into the gas layer pipe preheats the liquid carbon dioxide in the liquid layer pipe, thereby reducing the heat absorption from the external environment during the vaporization of liquid carbon dioxide, thus increasing the lower limit of the external ambient temperature, reducing frost formation, and ensuring the heat exchange efficiency of the ambient temperature vaporizer. A flow-blocking sleeve is provided on the liquid layer pipe, and the flow-blocking sleeve is located inside the finned tube. The flow-blocking sleeve is used to separate the gaseous carbon dioxide and liquid carbon dioxide to prevent them from mixing.

[0009] Preferably, the finned tubes are star-shaped finned tubes, and the finned tubes are connected in series by thermally conductive aluminum fins. The star-shaped finned tubes increase the contact area between the finned tubes and the outside air, thereby improving the heat exchange efficiency. When liquid carbon dioxide flows inside the finned tubes, the star-shaped fins can quickly transfer heat to the outside air, realizing a highly efficient heat exchange process. The finned tubes are connected by thermally conductive aluminum fins, which ensures the stability of the installation between the finned tubes. At the same time, the temperature is transferred through the thermally conductive aluminum fins, which ensures the uniformity of temperature in the same height area of ​​the finned tubes as a whole, thereby ensuring the stability of the vaporization efficiency.

[0010] Preferably, the reciprocating assembly includes a drive shaft, a reciprocating bushing, a synchronization plate, a fixed bracket, and a cleaning ring. The drive shaft is fixedly connected to a motor and is located below the diverter pipe. The drive shaft has threads and a telescopic groove. The reciprocating bushing is slidably mounted on the drive shaft. The reciprocating bushing has a threaded groove that mates with the drive shaft. When liquid carbon dioxide vaporizes, the motor starts and rotates in both directions, thereby driving the drive shaft to rotate synchronously. The drive shaft engages with the threaded groove on the reciprocating bushing through its threads, thus driving the reciprocating bushing to reciprocate. The synchronization plate is fixedly mounted on the reciprocating bushing. Fixed brackets are linearly arrayed on the synchronization plate. Cleaning rings are fixedly mounted on the fixed brackets, each corresponding to a diverter pipe. The cleaning rings are slidably mounted on the diverter pipe. Mounted on the distribution tube, the reciprocating bearing drives the synchronous plate to move synchronously as it slides back and forth. The synchronous plate drives the cleaning ring to move synchronously through the fixed bracket. The cleaning ring reciprocates on the distribution tube, thus preventing the formation of condensate and frost on the distribution tube, thereby ensuring heat exchange between gaseous carbon dioxide and the outside air, and preventing the low bottom temperature from exacerbating the formation of condensate and frost. The cleaning fins are symmetrically installed on both sides of the fixed bracket. The cleaning fins have linearly arrayed friction patterns. When the fixed bracket reciprocates with the synchronous plate, it drives the cleaning fins to move synchronously. The cleaning fins clean the condensate and frost on both sides of the finned tube, thereby ensuring the heat exchange efficiency of the finned tube. At the same time, the friction patterns of the cleaning fins enhance the friction between the cleaning fins and the finned tube, thereby ensuring the defrosting efficiency of the finned tube.

[0011] Preferably, the synchronous plate has linearly arranged sliding grooves, which are slidably connected to the finned tube. When the synchronous plate slides back and forth with the reciprocating bushing, it contacts the bottom of the finned tube through the sliding grooves, thereby cleaning the condensate and frost at the bottom of the finned tube. This works in conjunction with cleaning the fins to simultaneously defrost, ensuring the defrosting efficiency at the bottom of the finned tube and preventing frost buildup at the bottom of the finned tube from reducing the vaporization efficiency.

[0012] Preferably, the cleaning ring is divided into a cleaning layer and a friction layer; the cleaning layer has symmetrical cleaning ramps on both sides, and the cleaning ring enhances the interaction force with the diversion pipe through the cleaning ramps, thereby improving the defrosting efficiency of the cleaning ring on the surface of the diversion pipe. The friction layer is fixedly installed inside the cleaning layer; the friction layer is made of a high frictional heat material, so that when the cleaning ring reciprocates on the diversion pipe and generates friction, it can generate high heat, thereby keeping the gaseous carbon dioxide in the diversion pipe warm, thus avoiding excessive heat loss of the gaseous carbon dioxide when exchanging heat with the bottom environment, which would affect the preheating effect on the liquid carbon dioxide. The high frictional heat material can be polytetrafluoroethylene or carbon fiber friction material.

[0013] Preferably, the cleaning fins are provided with vibration protrusions, which are in contact with the heat-conducting aluminum sheet. During the reciprocating motion of the cleaning fins, the cleaning fins drive the vibration protrusions to move synchronously. The vibration protrusions move relative to the heat-conducting aluminum sheet, which in turn causes friction with the heat-conducting aluminum sheet to generate vibration. The heat-conducting aluminum sheet transmits the vibration to the adjacent finned tubes, thereby causing the condensate on the finned tubes to detach, preventing the accumulation of condensate and the formation of frost.

[0014] Preferably, the rotating assembly includes a telescopic block, a telescopic spring, a transition ring, a driven shaft, and a support frame; the telescopic block is slidably mounted in the telescopic groove via the telescopic spring, the telescopic block has a right-angled triangular structure, and a transition ring is provided on the outer circumference of the telescopic block; the transition ring is rotatably mounted to the drive shaft, and a slot on the transition ring is engaged with the telescopic block; when the drive shaft rotates, the drive shaft drives the telescopic block to rotate synchronously, and the telescopic block drives the transition ring to rotate by engaging with the slot on the transition ring; a driven shaft is fixedly mounted on the transition ring; the driven shaft is rotatably mounted to the support frame, and an exhaust vent is rotatably mounted on the driven shaft. Fan blades; the support frame is fixedly connected to the machine frame, and an exhaust fan blade is rotatably installed inside the support frame. When the adapter ring rotates, it drives the driven shaft fixedly connected to it to rotate synchronously. The driven wheel drives the exhaust fan blade to rotate synchronously. The rotation of the exhaust fan blade disturbs the air in the bottom plate, thereby expelling the air at the bottom and removing a large amount of water molecules in the air at the bottom, achieving a dehumidification effect, reducing the generation of condensate, and thus preventing frost formation. During the rotation of the driven shaft, the support frame ensures the stability of its own rotation, thereby ensuring the stability of the exhaust fan blade's rotation. At the same time, the exhaust fan blade itself is protected by the support frame.

[0015] Preferably, the adapter ring is provided with a hemispherical limiting ring block, and the drive shaft is provided with a limiting ring groove that cooperates with the limiting block. The adapter ring realizes the rotational connection between the adapter ring and the drive shaft through the cooperation of the limiting ring block and the limiting ring groove, and plays a limiting role in the movement of the adapter ring. At the same time, the adapter ring also supports the drive shaft and reduces the vibration of the drive shaft during rotation.

[0016] Preferably, the adapter ring has a ring array of flow-enhancing blades. The flow-enhancing blades are used to work with the exhaust fan blades to enhance the exhaust effect of the wind. The flow-enhancing blades can fill the airflow gaps between the exhaust fan blades, thereby reducing eddies and airflow turbulence, making the overall airflow more uniform. At the same time, the flow direction of the airflow can be optimized by the tilt angle and position of the flow-enhancing blades, thereby increasing the gas velocity and improving the wind speed.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. A carbon dioxide vaporization device, wherein the present invention achieves preheating of liquid carbon dioxide by setting a diversion pipe and a flow-blocking sleeve, thereby reducing the heat that needs to be absorbed from the outside during the vaporization of liquid carbon dioxide, thereby increasing the lower limit of heat exchange temperature and reducing frosting efficiency.

[0018] 2. A carbon dioxide vaporization device, wherein the present invention cleans the condensate and frost at the bottom of the finned tube by means of a reciprocating component, thereby ensuring the heat exchange efficiency of the finned tube. At the same time, the condensate on the finned tube is shaken off by vibration, thus avoiding the accumulation of condensate on the finned tube.

[0019] 3. A carbon dioxide vaporization device. The present invention achieves the discharge of air from the bottom through a rotating component, thereby discharging a large number of water molecules contained in the air at the bottom, thus avoiding the problem of rapid frost formation caused by high humidity in the air at the bottom.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The present invention provides a technical solution: like Figures 1 to 14As shown, a carbon dioxide gasification device includes: a frame 1, a heat exchange channel 2, a diversion pipe 3, a motor 4, a reciprocating assembly 5, cleaning fins 6, a rotating assembly 7, and an exhaust fan blade 8; the frame 1, heat exchange channel 2, diversion pipe 3, motor 4, reciprocating assembly 5, cleaning fins 6, rotating assembly 7, and exhaust fan blade 8; the heat exchange channel 2 is fixedly installed on the frame 1; the heat exchange channel 2 is composed of a liquid inlet pipe 21, an exhaust pipe 22, and finned tubes 23, the liquid inlet pipe 21 and the exhaust pipe 22 are respectively installed at both ends of the frame 1, and multiple sets of finned tubes 23 are linearly arrayed between the liquid inlet pipe 21 and the exhaust pipe 22; the liquid inlet pipe A diversion pipe 3 is provided between the exhaust pipe 21 and the exhaust pipe 22, and the diversion pipe 3 is staggered with the finned tube 23; the motor 4 is fixedly installed on the frame 1, and a reciprocating assembly 5 is provided on one side of the motor 4. The reciprocating assembly 5 is provided with cleaning fins 6. The motor 4 drives the cleaning fins 6 to reciprocate through the reciprocating assembly 5 to contact the surface of the finned tube 23 for defrosting. A rotating assembly 7 is provided on one side of the reciprocating assembly 5. A fan blade is installed on the rotating assembly 7. The fan blade is rotatably installed on the frame 1. When the reciprocating assembly 5 is working, the reciprocating assembly 5 drives the exhaust fan blade 8 to rotate unidirectionally through the rotating assembly 7 to reduce air humidity; Specifically, a heat exchange channel 2 is fixedly installed on the frame 1. The heat exchange channel 2 consists of a liquid inlet pipe 21, an outlet pipe 22, and finned tubes 23. The liquid inlet pipe 21 and the outlet pipe 22 are respectively installed at both ends of the frame 1. Multiple sets of finned tubes 23 are linearly arranged between the liquid inlet pipe 21 and the outlet pipe 22. During vaporization, liquid carbon dioxide is first introduced into the finned tubes 23 through the liquid inlet pipe 21. The liquid carbon dioxide circulates from bottom to top. During the flow of liquid carbon dioxide, the liquid carbon dioxide exchanges heat with the outside air through the finned tubes 23, thereby causing the liquid carbon dioxide to absorb heat and rise in temperature, and then vaporize into gaseous carbon dioxide. In the subsequent flow process, it gradually exchanges heat with the outside air, so that the gaseous carbon dioxide is at the same temperature as the outside environment and completes vaporization. Then, the gaseous carbon dioxide is discharged through the outlet pipe 22 for collection. A diversion pipe 3 is provided between the liquid inlet pipe 21 and the gas outlet pipe 22. The diversion pipe 3 is staggered with the finned tube 23. The diversion pipe 3 guides part of the vaporized carbon dioxide to flow through the bottom of the finned tube 23, thereby exchanging heat with the air at the bottom of the finned tube 23, thus avoiding the phenomenon of condensation and frost formation on the finned tube 23 due to the low bottom temperature. The motor 4 is fixedly installed on the frame 1. A reciprocating assembly 5 is provided on one side of the motor 4. The reciprocating assembly 5 contains cleaning fins 6. The motor 4 drives the cleaning fins 6 to reciprocate through the reciprocating assembly 5 to contact the surface of the finned tube 23 for defrosting. When vaporizing liquid carbon dioxide, the motor 4 starts, thereby driving the reciprocating assembly 5 to move synchronously. The reciprocating assembly 5 drives the cleaning fins 6 to reciprocate, and the cleaning fins... 6. Clean the condensate and frost on the bottom of the finned tube 23 to avoid frost formation, which would reduce heat exchange efficiency and affect the vaporization effect. When frost forms on the finned tube 23, condensate will first appear on the finned tube 23. The condensate will gradually accumulate on the finned tube 23 and crystallize into frost as heat exchange proceeds, fixing it to the bottom of the finned tube 23. Therefore, when cleaning the finned tube 23, the cleaning fin 6 first cleans the condensate according to the reaction process to avoid the condensate from accumulating at the bottom of the finned tube 23 and causing frost formation. This prolongs the frost formation time and reduces the thickness of the frost. After the finned tube 23 is frosted, the cleaning fin 6 removes the frost from the fin surface to prevent the frost from fixing on the finned tube 23. A rotating component 7 is provided on one side of the reciprocating assembly 5. A fan blade is installed on the rotating component 7 and rotates on the frame 1. When the reciprocating assembly 5 is working, it drives the exhaust fan blade 8 to rotate in one direction through the rotating component 7 to reduce the air humidity. When the reciprocating assembly 5 is working, it drives the exhaust fan blade 8 to rotate through the rotating component 7. When the exhaust fan blade 8 rotates, it blows the airflow at the bottom, thereby avoiding the phenomenon of more water molecules at the bottom, which makes it easier for condensation and frost to form at the bottom of the finned tube 23. When the outside air exchanges heat with liquid carbon dioxide for vaporization, the temperature of the outside air gradually decreases from top to bottom, which causes water molecules at the bottom to condense, resulting in higher air humidity at the bottom and thus increasing the frosting phenomenon. At this time, the rotation of the exhaust fan blade 8 blows out the humid air at the bottom, thereby reducing the air humidity at the bottom and preventing the occurrence of frosting. At the same time, it blows out the cold air at the bottom for ventilation, avoiding the lower air temperature at the bottom from aggravating the frosting phenomenon.

[0024] In this embodiment, the liquid inlet pipe 21 is composed of a gas layer pipe 211 and a liquid layer pipe 212; the liquid layer pipe 212 is fixedly installed inside the gas layer pipe 211, and the gas layer pipe 211 is connected to the gas outlet pipe 22 through a diverter pipe 3; a flow-blocking sleeve 213 is provided on the liquid layer pipe 212, and the flow-blocking sleeve 213 is located inside the finned tube 23. Specifically, a liquid layer pipe 212 is fixedly installed inside the gas layer pipe 211. The liquid layer pipe 212 is used to introduce liquid carbon dioxide. The gas layer pipe 211 is connected to the outlet pipe 22 through a diverter pipe 3. The diverter pipe 3 discharges the partially heat-exchanged gaseous carbon dioxide inside the outlet pipe 22, allowing the gaseous carbon dioxide to pass through the bottom of the finned tube 23 and exchange heat with the air at the bottom of the finned tube 23. This prevents condensation and frost from forming on the surface of the finned tube 23 due to the low bottom temperature. Furthermore, introducing gaseous carbon dioxide into the gas layer pipe 211 preheats the liquid carbon dioxide in the liquid layer pipe 212, thereby reducing the heat absorption from the external environment during the vaporization of liquid carbon dioxide. This increases the lower limit of the external ambient temperature, further reducing frost formation and ensuring the heat exchange efficiency of the ambient air vaporizer. A flow-blocking sleeve is provided on the liquid layer pipe 212. 213, the flow-blocking sleeve 213 is located inside the finned tube 23. The isolation sleeve is used to separate gaseous carbon dioxide and liquid carbon dioxide to prevent them from mixing. Liquid carbon dioxide vaporizes in the finned tube 23 in seven forms: single-phase liquid, bubble flow, slug flow, stirred flow, annular flow, mist flow, and single-phase gas. When it is in the stirred flow state, strong convection evaporation has begun and preliminary vaporization has begun. When it reaches the mist flow state, vaporization is basically completed. Therefore, the height of the sleeve in this invention is set at the boundary between the mist flow region and the single-phase gas region. The single-phase liquid to the stirred flow region is the preheating zone of gaseous carbon dioxide to liquid carbon dioxide. The stirred flow to the mist flow is the vaporization zone of liquid carbon dioxide. After the mist flow is the heating zone of gaseous carbon dioxide. Gaseous carbon dioxide becomes more stable by exchanging heat with the outside air until the temperature of gaseous carbon dioxide is the same as the outside environment.

[0025] In this embodiment, the finned tube 23 is a star-shaped finned tube 23, and the finned tubes 23 are connected in series with each other by heat-conducting aluminum sheets 231. Specifically, the star-shaped finned tube 23 increases the contact area between the finned tube 23 and the outside air, thereby improving the heat exchange efficiency. When liquid carbon dioxide flows inside the finned tube 23, the star-shaped fins can quickly transfer heat to the outside air, realizing a highly efficient heat exchange process. The finned tubes 23 are connected by thermally conductive aluminum fins 231, which ensures the stability of the installation of the finned tubes 23. At the same time, the temperature is transferred through the thermally conductive aluminum fins 231, which ensures the uniformity of temperature in the same height area of ​​the finned tubes 23 as a whole, thereby ensuring the stability of the gasification efficiency.

[0026] In this embodiment, the reciprocating assembly 5 includes a drive shaft 51, a reciprocating bushing 52, a synchronization plate 53, a fixed bracket 54, and a cleaning ring 55. The drive shaft 51 is fixedly connected to the motor 4 and is located below the diverter pipe 3. The drive shaft 51 has threads and a telescopic groove 511. The reciprocating bushing 52 is slidably mounted on the drive shaft 51. The reciprocating bushing 52 has a threaded groove that mates with the drive shaft 51. The synchronization plate 53 is fixedly mounted on the reciprocating bushing 52. The fixed bracket 54 is linearly arrayed on the synchronization plate 53. The cleaning ring 55 is fixedly mounted on the fixed bracket 54. The cleaning ring 55 corresponds one-to-one with the diverter pipe 3 and is slidably mounted on the diverter pipe 3. The cleaning fins 6 are symmetrically mounted on both sides of the fixed bracket 54 and have linearly arrayed friction patterns 61 on the cleaning fins 6. Specifically, the drive shaft 51 is fixedly connected to the motor 4, and the drive shaft 51 is located below the diverter pipe 3. The drive shaft 51 has threads and a telescopic groove 511. A reciprocating bushing 52 is slidably mounted on the drive shaft 51. The reciprocating bushing 52 has a threaded groove that mates with the drive shaft 51. When the liquid carbon dioxide vaporizes, the motor 4 starts and rotates in both directions, thereby driving the drive shaft 51 to rotate synchronously. The drive shaft 51 engages with the threaded groove on the reciprocating bushing 52 through its threads, thereby driving the reciprocating bushing 52 to reciprocate. A synchronization plate 53 is fixedly mounted on the reciprocating bushing 52. Fixed brackets 54 are linearly arrayed on the synchronization plate 53. Cleaning rings 55 are fixedly mounted on the fixed brackets 54. Each cleaning ring 55 corresponds to a diverter pipe 3 and is slidably mounted on the diverter pipe 3. When the reciprocating bearing slides back and forth, it drives the reciprocating shaft 51 to rotate. The synchronous plate 53 moves synchronously, and the synchronous plate 53 drives the cleaning ring 55 to move synchronously through the fixed bracket 54. The cleaning ring 55 reciprocates on the diversion tube 3, thereby preventing the generation of condensate and frost on the diversion tube 3, thus ensuring the heat exchange between gaseous carbon dioxide and the outside air, and preventing the low bottom temperature from aggravating the generation of condensate and frost. The cleaning fins 6 are symmetrically installed on both sides of the fixed bracket 54. The cleaning fins 6 have linear array friction patterns 61. When the fixed bracket 54 reciprocates with the synchronous plate 53, the fixed bracket 54 drives the cleaning fins 6 to move synchronously. The cleaning fins 6 clean the condensate and frost on both sides of the finned tube 23, thereby ensuring the heat exchange efficiency of the finned tube 23. At the same time, the cleaning fins 6 enhance the friction between the cleaning fins 6 and the finned tube 23 through the friction patterns 61, thereby ensuring the defrosting efficiency of the cleaning fins 6 on the finned tube 23.

[0027] In this embodiment, the synchronization plate 53 has a linear array of sliding grooves 531, and the sliding grooves 531 are slidably connected to the finned tube 23; Specifically, when the synchronous plate 53 slides back and forth with the reciprocating bushing 52, the synchronous plate 53 contacts the bottom of the finned tube 23 through the sliding groove 531, thereby cleaning the condensate and frost at the bottom of the finned tube 23, thus cooperating with the cleaning fin 6 to defrost synchronously, ensuring the defrosting efficiency of the bottom of the finned tube 23, and avoiding the reduction of gasification efficiency caused by frost at the bottom of the finned tube 23.

[0028] In this embodiment, the cleaning ring 55 is divided into a cleaning layer 551 and a friction layer 52; the cleaning layer 551 has symmetrical cleaning inclined surfaces 5511 on both sides, and the friction layer 52 is fixedly installed inside the cleaning layer 551; the friction layer 52 is made of a high frictional heat material. Specifically, the cleaning layer 551 has symmetrical cleaning ramps 5511 on both sides. The cleaning ring 55 enhances the interaction force between the cleaning ring 55 and the diversion pipe 3 through the cleaning ramps 5511, thereby enhancing the defrosting efficiency of the cleaning ring 55 on the surface of the diversion pipe 3. A friction layer 52 is fixedly installed inside the cleaning layer 551. The friction layer 52 is made of a high frictional heat material. The high frictional heat material in the friction layer 52 allows the cleaning ring 55 to generate high heat when it reciprocates and rubs on the diversion pipe 3, thereby keeping the gaseous carbon dioxide in the diversion pipe 3 warm. This prevents the gaseous carbon dioxide from consuming too much heat when exchanging heat with the bottom environment, which would affect the preheating effect on the liquid carbon dioxide. The high frictional heat material can be polytetrafluoroethylene or carbon fiber friction material.

[0029] In this embodiment, the cleaning fin 6 is provided with a vibration protrusion 62, which is in contact with the heat-conducting aluminum sheet 231; Specifically, during the reciprocating motion of the cleaning fin 6, the cleaning fin 6 drives the vibrating protrusion 62 to move synchronously. The vibrating protrusion 62 moves relative to the heat-conducting aluminum fin 231, which in turn causes the heat-conducting aluminum fin 231 to vibrate due to friction. The heat-conducting aluminum fin 231 transmits the vibration to the adjacent finned tube 23, thereby causing the condensate on the finned tube 23 to detach, preventing the accumulation of condensate and the formation of frost.

[0030] In this embodiment, the rotating assembly 7 includes a telescopic block 71, a telescopic spring 72, a transition ring 73, a driven shaft 74, and a support frame 75. The telescopic block 71 is slidably installed in the telescopic groove 511 via the telescopic spring 72. The telescopic block 71 is a right-angled triangular structure 711, and a transition ring 73 is provided on the outer circumference of the telescopic block 71. The transition ring 73 is rotatably installed with the drive shaft 51. The transition ring 73 is provided with a slot 731 that cooperates with the telescopic block 71. The driven shaft 74 is fixedly installed on the transition ring 73.

The support frame 75 is fixedly connected to the frame 1, and the exhaust fan blade 8 is rotatably installed inside the support frame 75. Specifically, the telescopic block 71 is slidably installed in the telescopic groove 511 via the telescopic spring 72. The telescopic block 71 is a right-angled triangular structure 711, and a transition ring 73 is provided on the outer circumference of the telescopic block 71. The transition ring 73 is rotatably installed with the drive shaft 51, and a slot 731 that cooperates with the telescopic block 71 is provided on the transition ring 73. When the drive shaft 51 rotates, the drive shaft 51 drives the telescopic block 71 to rotate synchronously via the telescopic spring 72. The telescopic block 71 drives the transition ring 73 to rotate by cooperating with the slot on the transition ring 73. The transition ring 73 is fixedly mounted on the transition ring 73. The system is equipped with a driven shaft 74; the driven shaft 74 is rotatably mounted to the support frame 75, and an exhaust fan blade 8 is rotatably mounted on the driven shaft 74; the support frame 75 is fixedly connected to the frame 1, and the exhaust fan blade 8 is rotatably mounted inside the support frame 75. When the adapter ring 73 rotates, it drives the driven shaft 74, which is fixedly connected to it, to rotate synchronously. The driven wheel drives the exhaust fan blade 8 to rotate synchronously. The rotation of the exhaust fan blade 8 disturbs the air at the bottom plate, thereby expelling the air at the bottom and removing a large amount of water molecules from the air at the bottom, achieving a dehumidification effect, reducing the generation of condensate, and thus preventing condensation. The occurrence of frost is ensured by the support frame 75 during the rotation of the driven shaft 74, thus ensuring the stability of the exhaust fan blade 8. Simultaneously, the support frame 75 provides some protection for the exhaust fan blade 8. When the motor 4 rotates forward, the drive shaft 51 drives the reciprocating sleeve 52 to slide along the direction of the exhaust fan blade 8. At this time, the telescopic block 71 engages with the right-angled side of the right-angled triangle structure 711 and the right-angled side of the inner groove 731 of the adapter ring 73, thereby squeezing and pushing the adapter ring 73 to rotate through the right-angled triangle structure 711. When the motor 4 reverses, the telescopic block 71 also reverses synchronously with the drive shaft 51. The hypotenuse of the right-angled triangular structure 711 of the telescopic block 71 presses against the hypotenuse of the slot 731, thereby squeezing the telescopic spring 72 into the telescopic groove 511 under the action of the slot 731. This keeps the adapter ring 73 fixed. The unidirectional rotation of the adapter ring 73 causes the exhaust fan blade 8 to rotate in only one direction, exhausting air in only one direction. This prevents the forward and reverse rotation of the exhaust fan blade 8 from affecting the airflow at the bottom, thus affecting the exhaust of air from the bottom and the removal of moisture.

[0031] In this embodiment, the adapter ring 73 is provided with a hemispherical limiting ring block 732, and the drive shaft 51 is provided with a limiting ring groove 512 that cooperates with the limiting block; Specifically, the adapter ring 73 achieves the rotational connection between the adapter ring 73 and the drive shaft 51 through the cooperation of the limiting ring block 732 and the limiting ring groove 512, and plays a limiting role in the movement of the adapter ring 73. At the same time, the adapter ring 73 also supports the drive shaft 51, reducing the vibration of the drive shaft 51 when it rotates.

[0032] In this embodiment, the adapter ring 73 has a ring array of flow booster blades 733; Specifically, the booster blade 733 is used in conjunction with the exhaust fan blade 8 to enhance the exhaust effect. The booster blade 733 can fill the airflow gaps between the blades of the exhaust fan blade 8, thereby reducing eddies and airflow turbulence, making the overall airflow more uniform. At the same time, the tilt angle and position of the booster blade 733 can optimize the airflow direction, thereby increasing the gas velocity and improving the wind speed.

[0033] When the carbon dioxide vaporization device of the present invention is in use, liquid carbon dioxide is first introduced into the finned tube 23 through the liquid layer tube 212. After the liquid carbon dioxide is vaporized, most of it is discharged from the gas outlet tube 22, and a small part enters the gas layer tube 211 through the diversion tube 3 to preheat the liquid carbon dioxide. When liquid carbon dioxide is vaporized, motor 4 starts rotating forward first. Motor 4 drives drive shaft 51 to rotate forward. Drive shaft 51 drives reciprocating sleeve 52 to slide along the direction of exhaust fan blade 8. Reciprocating sleeve 52 drives synchronous plate 53 to move synchronously. Synchronous plate 53 drives fixed bracket 54 to move synchronously. Fixed bracket 54 drives cleaning ring 55 to slide along diversion pipe 3 to clean diversion pipe 3. At the same time, fixed bracket 54 drives cleaning fins 6 to clean the bottom of finned tube 23. When drive shaft 51 rotates forward with motor 4, drive shaft 51 drives telescopic block 71 to rotate synchronously through telescopic spring 72. Telescopic block 71 squeezes slot 731 to drive adapter ring 73 to rotate. Adapter ring 73 drives driven wheel to rotate. Driven wheel drives exhaust fan blade 8 to rotate. When the reciprocating sleeve 52 moves to the top along the direction of the exhaust fan blade 8, the motor 4 reverses and drives the drive shaft 51 to reverse. The drive shaft 51 drives the reciprocating sleeve 52 to reset, and the reciprocating sleeve 52 drives the synchronous plate 53 to move synchronously. The synchronous plate 53 drives the fixed bracket 54 to move synchronously, and the fixed bracket 54 simultaneously drives the cleaning ring 55 and the cleaning fin 6 to slide synchronously. When the drive shaft 51 flips, the telescopic block 71 disengages from the slot 731, thereby keeping the adapter ring 73 fixed, thus keeping the exhaust fan blade 8 fixed. When the drive shaft 51 rotates forward again, the telescopic block 71 enters the slot 731 and drives the adapter ring 73 to rotate again.
