[0002] With the increasing global awareness of environmental protection and concerns about dependence on fossil fuels, the development of clean and efficient alternative energy has become an important topic in the shipping industry. As a low-carbon and renewable energy carrier, methanol can not only provide a clean and efficient power source for ships, but also reduce operating costs, which is in line with the general trend of global energy structure transformation and sustainable development. By converting it into hydrogen through reforming hydrogen production technology to provide power for ships, it has broad application prospects.

The power output unit uses the purified hydrogen for ship engines to achieve efficient power output;

[0024] 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.

Due to the reason of the self-weight of the expandable ring and the delivery channel, the present invention is in an unexpanded state, which is beneficial to being sent into the storage tank. And the operation of admitting air into the expandable ring is simple, just press the shielding piece continuously.

[0029] 3. By using the cooperation between the connecting disc one and the connecting disc two, the present invention can meet the requirements of admitting air, and can also quickly convert into the release state after admitting air, thereby ensuring the stability during the movement of the ship.

[0030] 4.

During the installation of a number of the swelling rings 124, it can be installed in a fan shape and is connected to the corresponding distribution channels 123;

[0055] In the initial stage, not all the air is introduced into the swelling ring 124. Due to the self-weight of the swelling ring 124 and the distribution channel 123, the swelling ring 124 is located below the distribution channel 123. After all the air is introduced, it floats on the methanol liquid surface in the containing tank 13. And a foam block can be installed on the swelling ring 124.

[0063] A method for a marine power plant for highly efficient hydrogen production by methanol reforming, using the equipment described in any one of claims 1-9, further comprising the following steps:

[0064] S1: During the operation of the ship, methanol is accommodated via an open hole, and the methanol in the open hole can be unloaded through a discharge channel below the open hole for conversion;

[0065] S2: Methanol is introduced into the reforming reaction unit to efficiently convert methanol into hydrogen. Then, it is introduced into the hydrogen purification unit to remove impurities and improve the hydrogen purity. The power output unit uses the purified hydrogen for the ship engine to achieve efficient power output;

[0066] S3: When gaseous products are precipitated from methanol in the open hole due to the movement of the ship, during the period when the gaseous products precipitated from methanol cause a gradually increasing compressive impulse in the receiving tank, the release rod can be displaced towards the top. When the compressive impulse rises to a certain level, the release rod can be completely displaced towards the top to the top of the delivery hole A;

[0067] S4: The precipitated gaseous products in the receiving tank will be displaced to the top of the connecting disc one via the delivery hole A, and then released through the release channel. Then, they can be collected via an external tank connected to the release channel.

[0068] In this solution, the circular shell 17 can be first assembled onto the sealing sheet 16, and then the sealing sheet 16 is assembled onto the retaining ring 15. At this time, the swelling beads 122, the distribution channel 123, and the swelling ring 124 are all inside the receiving tank 13, and the orientations between the delivery hole A 138 and the second release hole deviate from each other;

[0069] Then, press the shielding sheet 120. During the displacement of the shielding sheet 120 towards the bottom, it can drive the connecting disc two 136 to move towards the bottom together. The movement of the connecting disc two 136 towards the bottom can send the air below the connecting disc two 136 into the swelling beads 122, and then into the swelling ring 124 through the distribution channel 123. However, during the movement of the connecting disc two 136 towards the top, the surrounding air can be sent into the area at the bottom of the circular shell 17 inside the connecting disc two 136 through the balance channel 127. During the movement of the connecting disc two 136 towards the top, a small amount of air that has moved into the swelling beads 122 can move back into the circular shell 17 again. This does not affect the operation and is a small amount compared to the air introduced from the balance channel 127. Then, as the air continues to be sent in, the swelling ring 124 can expand, and then under the influence of methanol, it can drive the distribution channel 123 to rotate, thus floating on the methanol in the receiving tank 13. Then, remove the external force pressing on the shielding sheet 120;

[0070] Through an external force, the shutter 120 is threadedly assembled in the assembly hole 18. During this period, the shutter 120 rotates. Through the threaded installation, the shutter 120 can rotate a specific angle, so that the release hole 2 and the external delivery hole A138 are connected to each other. The release rod 139 in the external delivery hole A138 is in an unobstructed stage. During the movement following the ship, when the gaseous products precipitated from methanol cause a gradually increasing compressive impulse in the receiving tank 13, the release rod 139 can be displaced towards the top. When the compressive impulse rises to a specific period, the release rod 139 can be completely displaced towards the top to the top of the external delivery hole A138. In this way, the precipitated gaseous products in the receiving tank 13 will be displaced through the external delivery hole A138 to the top of the connecting disc 133, and then released through the release channel 126. Then, it can be collected through the external connection of the release channel 126 to the tank body.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
