Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of seawater overflow channels for open-frame seawater vaporizers, and in particular to a drainage device for a seawater overflow channel of an open-frame seawater vaporizer. Background Technology
[0002] After the ORV (open rack vaporizer) at an LNG receiving terminal has finished operating, the plug at the bottom of the seawater overflow tank must be manually removed to drain the remaining seawater. However, the plug is often located in inconvenient positions, such as the upper part of the overflow tank or the lower part of the walkway grating. Common methods at LNG receiving terminals include either having operators climb the overflow tank to remove the plug, or installing a walkway grating with holes for the plug to be removed.
[0003] 1. The process of climbing the seawater overflow channel to remove the plug poses a safety risk to the operator, such as stepping into the air or falling.

[0033] This utility model provides a drainage device for the seawater overflow trough of an open-frame seawater vaporizer, mainly used for discharging residual seawater from the overflow trough of an open-frame seawater vaporizer. It replaces the traditional overflow trough plug with a seawater discharge pipe (drainage pipe), extending the pipe to an easily accessible location. The discharge is controlled by a valve (drainage valve) on the pipe, allowing for more convenient, safe, and efficient seawater discharge. The drainage structure of the ORV seawater overflow trough is modified and optimized, eliminating the overflow plug design. A seawater drain pipe is connected to the overflow trough's drain hole, and the discharge is controlled by the valve on the drain pipe.
[0034] like Figure 1 As shown, the bottom of the seawater overflow trough 1 is provided with a seawater drainage hole 2, and the drainage pipe 3 is connected to the seawater drainage hole 2.

[0036] like Figure 1 As shown, the drainage pipe 3 is further connected to the bottom of the seawater overflow trough 1.
[0037] The beneficial effect of adopting the above-mentioned further technical solution is that it facilitates the discharge of seawater inside the seawater overflow channel through the drainage pipe under its own gravity.
[0038] like Figure 1 As shown, the seawater overflow channel 1 is further described as having an open top structure.
[0039] The beneficial effects of adopting the above-mentioned further technical solution are: it facilitates the injection of water into the seawater overflow channel by the seawater pump, and facilitates the uniform outflow of seawater from the top of the seawater overflow channel.
[0040] like Figure 1 As shown, the seawater overflow channel 1 is further described as a cuboid structure.
[0041] The beneficial effect of adopting the above-mentioned further technical solution is to improve the applicability of seawater overflow channels.
[0042] like Figure 1 As shown, further, there are two drainage pipes 3 and two drainage valves 4. The two drainage pipes 3 are connected to the bottom sides of the seawater overflow channel 1 in a one-to-one correspondence, and the two drainage valves 4 are installed on the two drainage pipes 3 in a one-to-one correspondence.

[0052] Before the ORV is put into operation, all valves (drain valves) on the seawater discharge pipe (drainage pipe) should be closed.
[0053] Start the seawater pump, and seawater flows into the seawater overflow channel through the seawater pipe (drainage pipe), and flows out evenly from the top of the seawater overflow channel. The ORV is now in normal operation.
[0054] After the ORV is put into operation, the seawater pump is stopped, and seawater no longer flows out from the top of the seawater overflow channel. The remaining seawater remains inside the seawater overflow channel.
[0055] Open the discharge valve (drain valve) on the seawater discharge pipe (drainage pipe) to discharge the seawater remaining inside the seawater overflow tank through the seawater discharge pipe (drainage pipe).
[0056] Close the seawater discharge valve.
