Description

Technical Field

[0001] The utility model relates to the technical field of ship manufacturing, in particular to a ship methanol supply cabin. Background Art

[0002] Current ship navigation regulations have increasingly stringent requirements for emissions generated during engine operation. The International Maritime Organization (IMO) and many other international regulations have greatly reduced greenhouse gas emissions and reduced marine air pollution. Methanol fuel does not contain sulfur, so it can meet the IMO's sulfur emission limits. At the same time, methanol fuel also contains very few particles, so it also meets the IMO's particle emission requirements.

[0003] For example, the patent with publication number CN 204507165 U discloses "a methanol tank structure of a ship, comprising a tank body, wherein a left methanol tank and a right methanol tank are arranged in the tank body, the left methanol tank and the right methanol tank are separated by a first isolation tank and a partition, the partition is arranged above the first isolation tank, a ventilation channel is arranged on the partition, the ventilation channel connects the left methanol tank and the right methanol tank, a ventilation pipe is arranged above the left methanol tank, and a second isolation tank is arranged above the left methanol tank and the right methanol tank."

[0004] However, the above-mentioned methanol tank structure does not have a cooling function. During the storage of methanol, if the temperature of the methanol is too high, it is easy to cause the stability of the methanol to decrease, thereby causing the methanol to decompose or deteriorate.

[0005] In addition, the patent with publication number CN 220199521 U discloses “a layout structure of a container ship equipped with a methanol storage tank, comprising a container ship body, a container placement seat is arranged on the top of the container ship body, a container body is placed in the inner cavity of the container placement seat, a methanol storage tank is connected to the inner cavity of the container ship body by bolts, a static electricity removal mechanism is arranged at the bottom of the inner cavity of the methanol storage tank, and a refrigeration mechanism is arranged on the surface of the methanol storage tank.

[0006] Although the above structure is provided with a refrigeration mechanism, the refrigeration mechanism is arranged on the surface of the methanol storage tank, which has poor compactness and requires more layout space. The increase in layout space also brings about an increase in the danger range, and the range that needs to be monitored is also larger, the cost is higher, and the economy is poor.

[0035] The working principle and beneficial effects of the above technical solution are as follows: the partition plate 7 is arranged in a vertical groove shape, which has greater stability; in addition, a ventilation pipe 8 is arranged to connect the left cabin 1 and the right cabin 2, which can effectively reduce the scope of the dangerous area, improve safety and enhance practicality.

[0036] Example 3

[0037] On the basis of the above-mentioned embodiments 1-2, Figure 1 As shown, a methanol injection pipe 10 is provided through the right cabin 2, and a valve body 1 is provided on the methanol injection pipe 10.

[0038] Preferably, an inert gas injection pipe 9 is provided through the right cabin 2 , and a valve body 2 is provided on the inert gas injection pipe 9 .

[0039] Preferably, an oxygen concentration detector 6 is provided in both the left cabin 1 and the right cabin 2, and a pressure sensor 5 is also provided through the left cabin 1;

[0040] The left compartment 1 and the right compartment 2 are also provided with liquid level indicators 11 .

When the valve body 1 and / or the valve body 2 fails and cannot be opened or closed, the controller 1 will also control the alarm 12 to sound an alarm. By setting the above structure, the entire methanol supply chamber can be effectively protected, thereby ensuring the safe use of methanol fuel and the safe operation of the ship.

When the temperature reaches the preset temperature (the preset temperature is determined by the technicians in this field), the water pump 27 is started by the controller 22, and the water pump 27 transports the coolant to the output pipe 21, and then the coolant enters the coil 13 and the U-shaped tube 1 26, the coil 13 cools the methanol in the left cabin 1, and then the coolant flows through the coil 13 and flows back to the cooling box 15, the U-shaped tube 1 26 transports the coolant to the coil 2 19, the coil 2 19 cools the methanol in the right cabin 2, and then the coolant flows through the coil 2 19, the U-shaped tube 2 17 and the input pipe 20 and flows back to the cooling box 15;
