Description

With the increase of oxygen demand in the production system, when the vaporizer needs to be in continuous operation for 24 hours, long-time operation is easy to cause frost on the surface of the equipment and cannot be naturally volatilized, which not only significantly reduces the vaporization efficiency of the vaporizer, causes the outlet oxygen temperature to drop, but also may cause liquid oxygen entrainment phenomenon due to the outlet temperature of-10℃, and the entrained liquid oxygen will instantaneously vaporize and expand after entering the normal temperature oxygen pipeline, causing the safety risk of pipeline burst.

For those skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0022] Please refer to Figures 1-7 A frost and deicing device for vaporizer, comprising a support 1, a plurality of deicing assemblies 2 are rotatably connected in the support 1 through bearings, and a drive motor 3 is connected to the top surface of the support 1 through bolts; The deicing assembly 2 comprises a sleeve pipe 21, a sleeve ring 22 is connected to the outer periphery of the sleeve pipe 21 through bolts, an ear 23 is fixedly connected to the outer periphery of the sleeve ring 22, a pipe head 24 is connected to the inner side of the ear 23 through bolts, a steel wire rope 25 is fixedly connected to the outer periphery of the pipe head 24, a transparent pipe 26 is rotatably connected to the inside of the sleeve pipe 21 through a bearing, a heating wire 27 is installed in the transparent pipe 26, a conductive terminal 28 is fixedly connected to the top end of the transparent pipe 26, a rectangular slot 29 is formed in the outer periphery of the sleeve pipe 21, and a double-layer synchronous wheel 210 is fixedly connected to the position close to the top end of the outer periphery of the sleeve pipe 21, a synchronous belt 211 is meshingly connected to the outer periphery of the double-layer synchronous wheel 210, and a connecting frame 212 is connected to the outer surface of the sleeve pipe 21 through a bearing.

[0023] Further, the connecting frame 212 has four connecting plates, one end of each connecting plate is fixedly connected to a group of heat exchange pipe groups 4, the heat exchange pipe group 4 comprises a vaporization pipe 41, and six fins 42 are welded around the axial direction of the outer wall of the vaporization pipe 41.

[0024] Further, the heat exchange pipe group 4 further comprises a bend pipe 43, the bottom end of the bend pipe 43 is fixedly connected to the vaporization pipe 41, and the heat exchange pipe group 4 is provided with a plurality of groups in a matrix manner, wherein the bottom end of the vaporization pipe 41 of a plurality of heat exchange pipe groups 4 located on one side of the matrix is fixedly connected to a liquid inlet pipe 5, and the top end of another plurality of heat exchange pipe groups 4 located on the other side of the matrix is fixedly connected to a gas outlet pipe 6.

[0025] The low-temperature liquid (such as liquid nitrogen, liquid oxygen, etc.) is pumped into the vaporization pipes 41 of a plurality of heat exchange pipe groups 4 through the liquid inlet pipe 5, and the low-temperature liquid can flow in the plurality of vaporization pipes 41 and the bend pipes 43 due to the communication of the vaporization pipes 41 of other heat exchange pipe groups 4 through the setting of the bend pipes 43; the six fins 42 (a plurality of heat dissipation holes are formed in the fins 42) welded on the outer wall of the vaporization pipe 41 increase the contact area with the outside air, and cooperate with the fins 42 to help the outside heat to be transmitted to the vaporization pipe 41 and the internal low-temperature liquid, so that the low-temperature liquid is continuously heated to complete the phase change of vaporization and is converted into gas; the generated gas is collected through the gas outlet pipe 6, flows into the tee pipe 7 connected to the flange at one end of the gas outlet pipe 6, and finally the gas is transported to the subsequent use system from the gas conveying pipe, thereby completing the conversion of the low-temperature liquid into gas.

[0026] Further, one end of the gas outlet pipe 6 is connected to the tee pipe 7 through a flange, the middle end of the tee pipe 7 is threadedly connected to a temperature sensor 8, the probe end of the temperature sensor 8 extends into the inside of the tee pipe 7, and the end of the tee pipe 7 away from the gas outlet pipe 6 is connected to a gas conveying pipe through a flange.

[0027] By setting the matrix heat exchange pipe group 4, the liquid inlet pipe 5 and the gas outlet pipe 6 and other components, a vaporizer is formed. In the case of large gas consumption, an additional vaporizer with the same structure can be added to realize the parallel use or independent switching operation of the two vaporizers. In this way, when the two vaporizers are used at the same time, the matrix heat exchange pipe group 4 of the two vaporizers can jointly undertake the task of vaporizing low-temperature liquid, greatly increasing the vaporization amount and gas output per unit time of the low-temperature liquid, effectively meeting the rapidly increasing demand for oxygen in industrial production, and at the same time, it is beneficial to reduce the icing of the outer surface of the vaporizer. In addition, by setting the temperature sensor 8, the gas temperature in the three-way pipe 7 can be monitored in real time, and the controller can coordinate the operating state of the two devices according to the monitoring data to ensure that the gas output temperature is stable and there is no risk of liquid oxygen entrainment. When one of the vaporizers is iced due to long-term operation, the remote terminal controller can be switched to the other vaporizer for independent operation to avoid the interruption of the entire oxygen supply system due to the shutdown of a single device. At the same time, the deicing assembly 2 can be started to deice the iced vaporizer.

[0028] Further, the outer surface of the fin 42 is provided with a plurality of heat dissipation holes along the axial direction of the vaporization pipe 41. The conductive terminal 28 is connected to a power supply device through a wire. The heating wire 27 is spirally arranged along the axial direction of the transparent pipe 26, and the spiral pitch of the heating wire 27 is 8-12 mm. A gap of 2-3 mm is reserved between the heating wire 27 and the inner wall of the transparent pipe 26, and the gap is filled with heat-conducting silicone grease.

[0029] When deicing is needed, the conductive terminal 28 fixedly connected to the top end of the transparent pipe 26 is connected to an external power supply device to establish an electric circuit. After being powered on, the heating wire 27 begins to generate heat. Since a gap of 2-3 mm is reserved between the heating wire 27 and the inner wall of the transparent pipe 26, and the gap is filled with heat-conducting silicone grease, heat can be efficiently transferred to the outer surface of the transparent pipe 26. Then, the high-thermal-conductivity ceramic coating sprayed on the outer circumferential surface of the transparent pipe 26 further accelerates heat conduction, so that heat is quickly dissipated from the rectangular groove 29 and smoothly spreads to the surfaces of the vaporization pipe 41 and the fin 42 of the heat exchange pipe group 4. Since the heat dissipation holes are also provided on the outer surface of the fin 42, heat transfer is facilitated. Finally, the heat transferred to the surfaces of the vaporization pipe 41 and the fin 42 directly acts on the frost layer and ice layer condensed thereon, causing the frost layer to quickly melt and the ice layer to gradually melt away.

[0030] Further, the matrix edges of the heat exchange pipe group 4 are welded with a plurality of square frames 9. The square frames 9 are connected by bolts with inclined braces 10. The lower surface of one of the square frames 9 located at the bottom end is connected by bolts with a support seat 11 near the corners. The inner side of the support seat 11 is welded with a water collecting tray, and one side of the water collecting tray is fixedly connected with a drain pipe.

[0031] By setting several boxes 9, and the box 9 through bolt connection between the diagonal bracing 10, box 9 and diagonal bracing 10 cooperate with each other, can form stable frame support to the matrix arrangement of multiple groups of heat exchange tube group 4, enhance the rigidity and stability of the overall structure of heat exchange tube group 4; the bottom support 11 provides a reliable bottom support for the whole device, so that the device can be placed stably on the ground; the water pan inside the support base 11 can effectively collect the melt water generated during the ice melting process of the vaporizer, prevent the melt water from randomly dripping to the ground to cause water accumulation and icing, avoid erosion and damage to the surrounding environment or equipment foundation of the device, and the drain pipe on one side of the water pan can timely guide the collected melt water to the designated position, ensure efficient and orderly melt water treatment, and maintain the cleanliness and safety of the device operating environment.

[0032] Further, the output shaft of the driving motor 3 is fixedly connected with a transmission rod 12, and the bottom end of the transmission rod 12 is fixedly connected with a driving synchronous wheel 13. The driving synchronous wheel 13 is in transmission connection with a synchronous belt 211 and one of the double-layer synchronous wheels 210.

[0033] Further, the outer circumferential surface of the sleeve ring 22 is fixedly connected with four groups of lugs 23 around the axis. The outer surface of the steel wire rope 25 is covered with a wear-resistant and crack-resistant rubber sleeve.

[0034] When the driving motor 3 is started, the output shaft will drive the transmission rod 12 to rotate synchronously, and the driving synchronous wheel 13 fixed at the bottom end of the transmission rod 12 will rotate. The driving synchronous wheel 13 transmits power to one of the double-layer synchronous wheels 210 through the synchronous belt 211 connected thereto. The double-layer synchronous wheels 210 of the multiple ice melting assemblies 2 are in meshing transmission through multiple synchronous belts 211 in sequence, thereby driving the outer sleeve pipes 21 of all the ice melting assemblies 2 to rotate synchronously. The sleeve ring 22 fixedly connected to the outer circumferential surface of the outer sleeve pipe 21 will rotate with the outer sleeve pipe 21, and the lugs 23, pipe heads 24 and steel wire ropes 25 will perform circular motion synchronously. During the rotation of the steel wire rope 25, the wear-resistant and crack-resistant rubber sleeve covering the outer surface of the steel wire rope 25 will periodically hit the fins 42 welded to the outer wall of the vaporization pipes 41 in the heat exchange tube group 4, thereby forming a vibration effect on the fins 42. When the ice layer on the outer surface of the fins 42 is preliminarily melted and loosened due to the heating of the heating wires 27, the vibration can destroy the adhesion between the ice layer and the surface of the fins 42, thereby facilitating the ice layer to fall off from the surface of the fins 42. The overall structure can greatly improve the ice melting efficiency.

[0035] Further, the rectangular side of the heat exchange tube group 4 is fixedly connected with a ladder, and a vertical rod 14 is welded to the top surface of the top box 9 at four corners. The top end of the vertical rod 14 is fixedly connected with a rain shield 15.

[0036] The ladder provides a safe and convenient climbing channel for the staff, facilitates the staff to perform daily inspection, maintenance or fault repair on high parts of the device, and improves the efficiency and safety of operation and maintenance without the need of additional temporary climbing facilities; and the rain shield 15 is fixed on the top frame 9 of the heat exchange pipe group 4 by the vertical rod 14, can effectively block the external precipitation such as rain and snow, avoid the rain directly falling on the core components such as the vaporization pipe 41, the fin 42 of the heat exchange pipe group 4 and the outer sleeve 21, the steel wire rope 25 of the deicing assembly 2, prevent the rain from contacting the low-temperature components to aggravate the frosting and icing phenomenon, and also reduce the corrosion and wear of the rain on the components, prolong the service life of the device as a whole.

[0037] In use, first, the low-temperature liquid is pumped into the vaporization pipes 41 of the heat exchange pipe groups 4 through the liquid inlet pipe 5, flows in the vaporization pipes 41 and the elbow pipes 43, uses the fins 42 to increase the contact area with the external air, makes the low-temperature liquid continuously absorb heat to complete the vaporization phase change, the generated gas is collected through the gas outlet pipe 6 and then flows into the three-way pipe 7, and finally is transported to the subsequent use system through the gas conveying pipe; when deicing, the conductive terminal 28 is connected with the external power supply, the heat generated by the heating wire 27 is transmitted to the transparent pipe 26 through the heat-conducting silicone grease, and then is diffused to the surfaces of the vaporization pipes 41 and the fins 42 through the rectangular grooves 29, so that the frost layer and the ice layer are gradually melted; at the same time, the driving motor 3 is started, all the outer sleeves 21 of the deicing assemblies 2 are driven to rotate through the transmission rod 12, the driving synchronous wheel 13 and the synchronous belt 211, the steel wire rope 25 periodically hits the fins 42 to generate vibration, and the ice layer is removed; the melt water generated by deicing is collected by the water pan and then is discharged through the drain pipe, at the same time, the rain shield 15 blocks the precipitation, the ladder facilitates the staff to perform inspection and maintenance, and the temperature sensor 8 monitors the gas temperature in real time to ensure the stable operation of the system.

[0038] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
