Description

Technical Field

[0001] This utility model relates to the field of vaporizer technology, and more specifically to an anti-icing structure for ambient air vaporizers. Background Technology

[0002] In modern society, ambient temperature vaporizers are widely used in the vaporization process of liquefied natural gas to convert liquefied natural gas into gaseous natural gas at ambient temperature and pressure.

[0004] However, the following drawbacks still exist: when the ambient temperature of the air-temperature vaporizer is low, the operating efficiency of the air-temperature vaporizer will decrease. In some areas, the low ambient temperature will also cause ice to form on the surface of the air-temperature vaporizer. This will not only cause equipment failure, but also increase the additional maintenance work, requiring manual cleaning at regular intervals, which will significantly increase the workload of workers.

[0027] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Reference Figures 1-4This utility model provides an anti-icing structure for an ambient air vaporizer, including a vaporizer body 11. The vaporizer body 11 has an external heat-insulating shell 1 that can form a sealed state. One inner wall of the heat-insulating shell 1 has several equidistantly distributed jet pipes 13 rotatably connected to it, with the jet pipes 13 passing through the vaporizer body 11. The other inner wall of the heat-insulating shell 1 has several connecting pipes 15 welded to it, corresponding to the jet pipes 13. The connecting pipes 15 and jet pipes 13 are connected by a rotary joint 16. The outer wall of the jet pipes 13 has several equidistantly distributed nozzles 19 welded to it, evenly divided into left and right groups, symmetrically arranged. The airflow from adjacent nozzles 19 partially overlaps. One side of the heat-insulating shell 1 has a power assembly for driving the multiple jet pipes 13 to rotate synchronously. The side of the heat-insulating shell 1 near the connecting pipes 15 has a guide assembly for inputting hot air into the connecting pipes 15. The flow assembly guides hot air into multiple connecting pipes 15, which then enter multiple jet pipes 13 through multiple rotary joints 16. The hot air is then ejected from multiple nozzles 19 onto the surface of the vaporizer body 11. Simultaneously, the power assembly is activated, driving the multiple jet pipes 13 to rotate synchronously. This ensures that the hot air evenly covers the surface of the vaporizer body 11, effectively preventing ice formation and ensuring that the vaporizer can still operate normally and stably in low-temperature environments. It also solves the problem of needing regular manual cleaning after existing air-temperature vaporizers freeze, greatly reducing the workload of workers. Furthermore, the airflow from two adjacent nozzles 19 partially overlaps, further enhancing the coverage effect of hot air on the surface of the vaporizer body 11. The insulation shell 1 also provides good insulation for the vaporizer body 11, reducing heat loss during transmission and further improving the working efficiency of the air-temperature vaporizer in low-temperature environments.

[0029] It should be noted that the vaporizer body 11 is existing technology, including the base tube, fins, inlet gas collecting pipe, outlet gas collecting pipe, etc. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0030] In this embodiment, the power assembly includes a slide rail 14 fixed to the side of the insulation shell 1 near the connecting pipe 15 by bolts. A slide frame 17 is slidably connected to one side of the slide rail 14 via a slide table. A rack 20 is fixed to the inner wall of the slide frame 17 by bolts. A number of jet pipes 13 are connected to gears 18 near the outer wall of the rotary joint 16 by keys, and the gears 18 mesh with the rack 20. An electric push rod 9 is installed on the top outer wall of the insulation shell 1. The piston end of the electric push rod 9 passes through the insulation shell 1 and is fixed to the slide frame 17. When the electric push rod 9 is activated, the piston end of the electric push rod 9 moves in a telescopic motion. The piston end drives the slide frame 17 to slide up and down along the direction of the slide rail 14. The slide frame 17 drives the rack 20 to move together with the slide frame 17. During the reciprocating motion of the rack 20, it drives the gears 18 to rotate reciprocally, thereby driving the multiple jet pipes 13 to rotate synchronously.

[0031] In this embodiment, the flow guiding assembly includes several equally spaced fixing brackets 6 fixed to one side of the insulation shell 1 by bolts. The outside of the fixing brackets 6 is provided with air guiding pipes 7 for flow guiding, and several connecting pipes 15 are all connected to the air guiding pipes 7. An air pump 10 is installed on the top of the insulation shell 1, and the air inlet pipe of the air pump 10 is connected to the air guiding pipe 7. A heating assembly is provided inside the air guiding pipe 7. The heating assembly includes a heating wire 21 installed inside the air guiding pipe 7, and both the heating wire 21 and the air guiding pipe 7 are spiral-shaped. The air guiding pipe 7 is a heat-insulating pipe. When the air pump 10 is started, it draws in external gas, which first enters the air guiding pipe 7. The heating wire 21 inside heats the gas. The heated gas then enters the jet pipe 13 through several connecting pipes 15 connected to the gas guide pipe 7, and finally is ejected from the nozzle 19 to heat the vaporizer body 11 and prevent it from freezing. At the same time, the gas guide pipe 7 is a heat insulation pipe, which can effectively reduce heat loss during transmission and improve heat utilization. It also greatly reduces the possibility of workers being burned due to accidental contact with the gas guide pipe 7, ensuring the safety of workers. The spiral heating wire 21 and the gas guide pipe 7 increase the contact area and contact time between the gas and the heating wire 21, so that the gas can be fully heated.

[0032] It should be noted that the heating wire 21, air pump 10, rotary joint 16, and electric push rod 9 are all existing technologies. Those skilled in the art can set them according to actual needs, and they will not be described in detail here.

[0033] In this embodiment, a drain pipe 5 is welded to the bottom of one side of the outer wall of the insulation shell 1, and the drain pipe 5 is connected to the insulation shell 1. The bottom inner wall of the insulation shell 1 is provided with an inclined surface 12 that slopes towards the drain pipe 5. When condensate is generated inside the insulation shell 1, the condensate will flow along the inclined surface 12 to the drain pipe 5 and be discharged outside the insulation shell 1 through the drain pipe 5. This can effectively prevent condensate from accumulating inside the insulation shell 1, prevent excessive water accumulation from affecting the normal operation of the vaporizer body 11, and also reduce corrosion and other problems that may be caused by water accumulation, thus extending the service life of the equipment.

[0034] In this embodiment, a manhole 2 is provided on one side of the insulation shell 1. A baffle 3 is detachably connected to one side of the insulation shell 1 and located at the manhole 2 by bolts. The size of the baffle 3 is larger than the size of the manhole 2. When it is necessary to inspect or maintain the gasifier body 11, the bolts fixing the baffle 3 are unscrewed, the baffle 3 is removed, and the worker can enter the interior of the insulation shell 1 through the manhole 2 to perform relevant operations.

[0035] In this embodiment, a thermometer 4 is installed on one side of the gas duct 7 in the heat insulation shell 1, and the detection end of the thermometer 4 passes through the heat insulation shell 1. The thermometer 4 can measure the temperature of the gas in the gas duct 7 in real time, so that the workers can understand the working status of the gasifier body 11 in a timely manner, thereby ensuring the stability and safety of the entire gasification process.

[0036] It should be noted that thermometer 4 is existing technology, and the model of thermometer 4 is digital thermometer DTM-411. Those skilled in the art can set it according to actual needs, which will not be elaborated here.

[0037] The use of this utility model involves the following steps:

[0038] S1: The air pump 10 starts and draws in outside gas. The gas first enters the air guide pipe 7. The heating wire 21 in the air guide pipe 7 heats the gas. The heated gas then enters several connecting pipes 15 through the air guide pipe 7. Then the hot gas enters several jet pipes 13 through several rotary joints 16 and is then sprayed out from several nozzles 19 onto the surface of the vaporizer body 11.

[0039] S2: At the same time, start the electric push rod 9. The piston end of the electric push rod 9 moves in extension and retraction. Its piston end drives the slide 17 to slide up and down along the slide rail 14. The slide 17 drives the rack 20 to move together with the slide 17. During the reciprocating motion of the rack 20, it will drive the gear 18 to rotate back and forth, thereby driving multiple jet pipes 13 to rotate back and forth synchronously.

[0040] S3: Finally, the condensate generated inside the insulation shell 1 will flow down the slope 12 to the drain pipe 5 and be discharged outside the insulation shell 1 through the drain pipe 5.

[0041] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship.
