Description

Technical Field

[0001] This invention relates to the field of liquid argon vaporizer technology, and in particular to a liquid argon air-temperature vaporizer. Background Technology

[0002] The backup liquid argon vaporization system for oxygen production in energy power plants vaporizes liquid argon from the backup liquid argon storage tank into gaseous argon using an ambient temperature vaporizer, which is then delivered to the user. The ambient temperature vaporizer works by exchanging heat between the cryogenic liquid inside the heat exchange tubes and the surrounding air, utilizing natural convection air from the atmosphere as a heat source to completely evaporate the liquid argon into gaseous argon. However, the vaporization efficiency of the ambient temperature vaporizer is affected by the ambient temperature: in low-temperature environments, ice will form on the outside of the liquid argon vaporizer, leading to a decrease in vaporization efficiency, especially noticeable in winter when temperatures are low. This is manifested in several ways, including:

[0003] (1) Affecting the vaporization rate: Ice formation on the outside of the liquid argon vaporizer will cause the temperature of the heat pipe surface to drop, which in turn affects the vaporization rate of liquid argon. Ice formation will reduce the heat transfer efficiency of the vaporizer, resulting in a slower vaporization process and affecting the supply of argon.

[0004] (2) Decreased equipment performance: The ice layer forms an insulating layer, reducing heat transfer and causing the liquid argon to remain in the vaporizer for a longer time, thus reducing vaporization efficiency. This not only affects the normal operation of the equipment but may also lead to a decrease in equipment performance and affect the stable supply of argon.

[0005] (3) Equipment Damage: Severe icing can increase the weight of the vaporizer and related piping, leading to equipment damage. The weight of the icing layer can also put pressure on equipment components, causing malfunction or damage.

[0006] (4) Safety Hazards: Icing can also pose safety hazards. If icing becomes severe, it may cause the vaporizer to malfunction, or even lead to a safety accident.

[0007] Existing methods for removing ice buildup on the exterior of vaporizers typically involve manual de-icing by on-site operators. This method is inefficient and unsafe. Falling ice can damage equipment below, causing secondary hazards. Furthermore, the confined space on-site hinders proper de-icing operations, resulting in low efficiency. Therefore, this invention provides a liquid argon air vaporizer capable of timely ice removal. Utility Model Content

[0011] A spray layer for spraying water onto the outer surface of the vaporizer body, wherein at least one spray layer is provided, and at least one spray layer is longitudinally distributed along the height of the vaporizer body;

[0012] A conveying component is used to convey water into the spray layer. The conveying component includes a conveying branch pipe disposed on each of the spray layers and a conveying main pipe that delivers water into each of the conveying branch pipes. The inlet of the conveying main pipe is connected to an external water supply device. Each of the conveying branch pipes is equipped with a sub-control valve, and the conveying main pipe is equipped with a main control valve.

[0013] Furthermore, the spray layer includes a rectangular spray pipe, and multiple spray branch pipes are uniformly arranged in the spray pipe along its transverse direction. The multiple spray branch pipes are connected to the spray pipe. Multiple spray nozzles are arranged on the spray pipe and the spray branch pipes along their length direction, and the spray nozzles face the vaporizer body.

[0014] Furthermore, the distance between two adjacent spray nozzles is 5 ± 0.5 cm.

[0015] Furthermore, a remote control ball valve is also provided on the main delivery pipe, and the remote control ball valve is located between the main control valve and the delivery branch pipe.

[0016] Furthermore, a vent pipe is provided between the remote control ball valve and the main control valve, and a vent control valve is provided on the vent pipe.

[0030] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] refer to Figure 1 , Figure 2 and Figure 3 The liquid argon air vaporizer provided in this embodiment includes a vaporizer body 1, on which a spray assembly is provided.

[0032] refer to Figure 1 , Figure 2 and Figure 3 The spray assembly includes a spray layer 2 and a conveyor 3. The spray layer 2 is used to spray water onto the outer surface of the vaporizer body 1. At least one spray layer 2 is provided, and the at least one spray layer 2 is longitudinally distributed along the height of the vaporizer body 1. In this example, there are two spray layers, one of which is located at the top of the vaporizer body and the other is located in the middle of the vaporizer body. The spray layer 2 includes a rectangular spray pipe 21. All four pipes of the rectangular spray pipe 21 can be detachably connected. Multiple spray branch pipes 22 are evenly arranged in the transverse direction inside the spray pipe 21. The multiple spray branch pipes 22 are connected to the spray pipe 21. The spray branch pipes 22 can also be detachably connected to the spray pipe 21. After the spray layer 2 is installed on the vaporizer body 1, it is fixed with iron wire. Multiple spray nozzles 23 are provided on the spray pipe 21 and the spray branch pipes 22 along their length direction. The spray nozzles 23 face the vaporizer body 1. The distance between two adjacent spray nozzles 23 is 5±0.5cm. In this example, the distance between two adjacent spray nozzles 23 is 5cm. This distance ensures that the sprayed water can completely cover the vaporizer body, resulting in a better de-icing effect.

[0033] refer to Figure 1 , Figure 2 and Figure 3 The conveying component 3 is used to deliver water into the spray layer 2. The conveying component 3 includes a conveying branch pipe 31 installed on each spray layer 2 and a main conveying pipe 32 that delivers water to each conveying branch pipe 31. The inlet of the main conveying pipe 32 is connected to an external water supply device 4, meaning the main conveying pipe 32 can be connected to the return water header of the expander oil cooler in the actual working area, delivering hot water from the expander oil cooler's return water header to the spray layer 2, making full use of on-site resources and saving water. In actual operation, this expander oil cooler is not far from the liquid argon air vaporizer. Each conveying branch pipe 31 is equipped with a sub-control valve 5, and the main conveying pipe 32 is equipped with a main control valve 6. The sub-control valves 5 control the on / off state of each spray layer 2, and the main control valve 6 controls the on / off state of the entire spray assembly. A metal hose 7 is detachably installed between the spray layer 2 and the outlet of the conveying branch pipe 31. The metal hose 7 is made of stainless steel and is connected by a plate handle quick connector. This method is simple and quick to operate during installation. The metal hose 7 makes it easy to connect the conveying branch pipe 31 and the spray layer 2, saving time and effort.

[0034] refer to Figure 1 , Figure 2 and Figure 3 A remote control ball valve 8 is also installed on the main delivery pipe 32, which is located between the main control valve 6 and the delivery branch pipe 31. The signal receiving end of the remote control ball valve 8 is connected to the signal output end of the control component in the control room. Both the main control valve and the branch control valve are in the open state. The remote control valve is used to control the on / off state of this spray assembly. When the outside temperature is low, the remote control ball valve 8 can be opened remotely to allow hot water to flow through the spray layer 2 onto the frozen vaporizer body 1, achieving online de-icing without the need for manual valve opening and closing by on-site personnel, thus reducing the workload of on-site operators.

[0035] refer to Figure 1 , Figure 2 and Figure 3 A drain pipe 9 is installed between the remote control ball valve 8 and the main control valve 6, and a drain control valve 10 is installed on the drain pipe 9. The position between the remote control ball valve 8 and the main control valve 6 is at the lowest point. When this spray assembly is not used to de-ice the vaporizer body 1, the drain control valve 10 is opened to drain the water in the main delivery pipe 32, the branch delivery pipe 31, and the spray layer 2, so as to prevent ice formation inside and affect the next use.

[0036] In summary, when the vaporizer body 1 freezes in a low-temperature environment, the spray assembly can perform online de-icing of the frozen vaporizer body 1, effectively alleviating the problems of reduced vaporization efficiency and insufficient argon supply caused by vaporizer icing, and ensuring stable production. At the same time, it solves the problems of low efficiency and unsafety of manual de-icing when the vaporizer freezes, reduces the labor intensity of employees, and eliminates on-site operation safety risks.
