[0063] A method for a ship power plant for efficiently producing hydrogen by reforming methanol, using the equipment described in any one of claims 1 to 9, further comprising the following steps:

[0064] S1: During the ship's activities, methanol is contained in the open hole, and the methanol in the open hole can be discharged through the discharge channel below the open hole for conversion;

[0065] S2: Methanol is introduced into the reforming reaction unit to be efficiently converted into hydrogen, and then introduced into the hydrogen purification unit to remove impurities and improve the purity of hydrogen. The power output unit uses the purified hydrogen for ship engines to achieve efficient power output;

[0066] S3: When methanol precipitates gaseous products in the open hole due to the movement of the ship, the gaseous products precipitated by methanol cause the pressure impulse in the holding tank to gradually increase, which can cause the release rod to move toward the top. When the pressure impulse rises to a certain level, all the release rods can move toward the top to the top of the delivery hole A.

[0067] S4: The gaseous products separated in the holding tank will be displaced to the top of the connecting disc 1 through the external delivery hole A, and then released through the release channel, and then can be collected by the external tank body through the release channel.

[0068] In this solution, the round shell 17 can be assembled onto the sealing piece 16 first, and then the sealing piece 16 can be assembled onto the retaining ring 15. At this time, the enlarged bead 122, the delivery channel 123 and the enlarged ring 124 are all in the containing tank 13, and the directions of the external delivery hole A138 and the release hole are offset from each other.

[0069] Then, the shielding piece 120 is pressed. During the displacement of the shielding piece 120 toward the bottom, the connecting disc 136 can be pulled to move toward the bottom together. The displacement of the connecting disc 136 toward the bottom can send the air under the connecting disc 136 into the expanding bead 122, and then send it into the expanding circle 124 through the distribution channel 123. However, during the displacement of the connecting disc 136 toward the top, the surrounding air can be sent into the area at the bottom of the connecting disc 136 in the round shell 17 through the balance channel 127. During the displacement of the connecting disc 136 toward the top, a small amount of air that has moved into the expanding bead 122 can be moved into the round shell 17 again. This does not hinder the operation. Compared with the air introduced by the self-balancing channel 127, the amount is small. Then, the continuous delivery of air can make the expanding circle 124 expand, and then the distribution channel 123 is pulled to rotate due to the methanol, thereby floating on the methanol in the containing tank 13, and then the external force pressing on the shielding piece 120 is removed;

[0070] Through external force, the shield 120 is threadedly assembled in the assembly hole 18. During this period, the shield 120 rotates. Through the threaded installation, the shield 120 can rotate at a specific angle, so that the release hole 2 and the external delivery hole A138 are connected to each other, and the release rod 139 in the external delivery hole A138 is in an unobstructed stage. During the period of following the ship's activities, the gaseous products precipitated by methanol cause the pressure impulse in the holding tank 13 to gradually increase, which can make the release rod 139 move toward the top. When the pressure impulse rises to a specific level, the release rod 139 can be completely moved toward the top to the top of the external delivery hole A138. In this way, the precipitated gaseous products in the holding tank 13 will be displaced to the top of the connecting disc 133 through the external delivery hole A138, and then released through the release channel 126, and then can be collected through the external tank body through the release channel 126.
