Description

Technical Field

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

[0002] At present, the main fuel used by ships is still fuel oil. However, in recent years, methanol has gradually been favored by shipowners as a new energy source. Its biggest advantage is that it can reduce the emission of harmful gases and carbon dioxide gases. The emission reduction effect of methanol is very obvious. The main engine burns methanol to generate power to propel the ship forward, and a tank is needed to store methanol fuel, that is, a methanol fuel tank. The relevant regulations require that an isolated empty tank be provided around the methanol fuel tank to protect the methanol fuel tank inside it.

[0003] The isolation compartments around conventional fuel tanks are usually only equipped with vent pipes to ensure normal ventilation of the isolation compartments. When a methanol fuel tank leaks, the methanol inside leaks into the isolation compartments. There is air in the isolation compartments, and the vapor generated by the methanol liquid mixes with the oxygen in the isolation compartments, which poses a risk of flammability and explosion.

[0004] Therefore, there is an urgent need for a methanol isolation tank and a ship to solve the above-mentioned technical problems. Utility Model Content

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

[0008] A shell, the shell is wrapped outside the methanol fuel tank and is spaced apart from the shell of the methanol fuel tank to form an isolation space;

[0014] As a preferred technical solution for the above-mentioned methanol isolation cabin, the above-mentioned first pipeline is provided with a one-way valve, which only allows inert gas to pass into the above-mentioned isolation space from the above-mentioned first pipeline.

[0019] A ship is also provided, comprising the above-mentioned methanol isolation cabin.

[0020] Beneficial effects of the utility model:

[0021] The utility model provides a methanol isolation cabin, comprising a shell, an air injection assembly and a ventilation assembly. The shell is wrapped outside the methanol fuel tank, and is spaced apart from the shell of the methanol fuel tank to form an isolation space; the air injection assembly comprises a first pipeline, one end of which is inserted into the isolation space, and can selectively introduce inert gas into the isolation space; the ventilation assembly comprises a second pipeline and a third pipeline, both of which are connected to the isolation space, the second pipeline can selectively connect the indoor and outdoor environments of the isolation space, and the third pipeline can selectively connect any one of the breathing valve and the first air pipe head.

[0022] Methanol fuel is stored in the methanol fuel tank, and a methanol isolation tank is set outside it to prevent the methanol fuel tank from being directly hit. When the methanol fuel tank leaks, the leaked methanol liquid can be confined in the isolation space and will not flow to other places. And when the crew needs to enter the isolation space to carry out inspection and maintenance near the methanol fuel tank, fresh air can be provided for the isolation space to facilitate the crew's work.

[0023] Specifically, under normal circumstances, the first pipeline of the ventilation component is closed, and the second pipeline and the third pipeline are opened. The gas in the isolation space can be connected to the outside through the second pipeline and / or the third pipeline for gas exchange; when a methanol fuel tank leaks, the methanol inside it leaks into the isolation space. At this time, it is necessary to first open the gas injection component and the ventilation component. At this time, the third pipeline is equipped with a first air pipe head, and inert gas is injected into the isolation space through the first pipeline. The inert gas occupies the isolation space and the original air in the isolation space is discharged through the second pipeline or the third pipeline to prevent methanol from exploding when in contact with air. After waiting for a period of time, close the second pipeline, remove the first air pipe head from the first pipeline, and then install the breathing valve on the first pipeline. The breathing valve is set with a threshold. When the air pressure in the isolation space is greater than the threshold, the breathing valve connects the indoor and outdoor environments of the isolation space, thereby limiting the overflow of inert gas.

[0024] Such an arrangement can improve the utilization efficiency of the inert gas and enhance the safety of the methanol isolation cabin. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] like Figure 1 and Figure 2As shown, the utility model provides a methanol isolation cabin, including a shell 10, an air injection assembly 20 and a ventilation assembly. The shell 10 is wrapped outside the methanol fuel tank 100, and is spaced apart from the shell 10 of the methanol fuel tank 100 to form an isolation space 11; the air injection assembly 20 includes a first pipe, one end of which is inserted into the isolation space 11, and can selectively introduce inert gas into the isolation space 11; the ventilation assembly includes a second pipe 31 and a third pipe 32, both of which are connected to the isolation space 11, the second pipe 31 can selectively connect the indoor and outdoor environments of the isolation space 11, and the third pipe 32 can selectively connect any one of the breathing valve 33 and the first air pipe head 34.

[0039] Methanol fuel is stored in the methanol fuel tank 100, and a methanol isolation tank is arranged outside the methanol fuel tank 100 to prevent the methanol fuel tank 100 from being directly hit. When the methanol fuel tank 100 leaks, the leaked methanol liquid can be confined in the isolation space 11 and will not flow to other places. When the crew needs to enter the isolation space 11 to carry out inspection and maintenance near the methanol fuel tank 100, fresh air can be provided for the isolation space 11 to facilitate the crew's work.

[0040] Specifically, under normal circumstances, the first pipeline of the ventilation component is closed, the second pipeline 31 and the third pipeline 32 are opened, and the gas in the isolation space 11 can be connected to the outside through the second pipeline 31 and / or the third pipeline 32 for gas exchange; when the methanol fuel tank 100 leaks, the methanol inside it leaks into the isolation space 11. At this time, it is necessary to first open the gas injection component 20 and the ventilation component. At this time, the third pipeline 32 is equipped with a first air pipe head 34, and inert gas is injected into the isolation space 11 through the first pipeline. The inert gas occupies the isolation space 11 and the original air in the isolation space 11 is discharged through the second pipeline 31 or the third pipeline 32 to prevent methanol from exploding when in contact with air. After waiting for a period of time, the second pipeline 31 is closed, the first air pipe head 34 is removed from the first pipeline, and the breathing valve 33 is installed on the first pipeline. The breathing valve 33 is set with a threshold. When the air pressure in the isolation space 11 is greater than the threshold, the breathing valve 33 is connected to the indoor and outdoor environments of the isolation space 11, thereby limiting the overflow of the inert gas.

[0041] Such an arrangement can improve the utilization efficiency of the inert gas and enhance the safety of the methanol isolation cabin.

[0042] Optionally, the methanol isolation chamber further includes a pressure monitoring device 40, which includes a sensing end and a display end. The sensing end is installed in the isolation space 11 and is used to obtain the air pressure value in the isolation space 11. The display end is located outside the isolation space 11 and is fixed to the shell 10, and is used to display the air pressure value in the isolation space 11. With such a configuration, the staff can obtain the internal pressure of the isolation space 11 through the pressure monitoring device 40 outside the isolation space 11. The opening and closing of the gas injection assembly 20 can be adjusted according to the internal pressure.

[0043] Optionally, the pressure monitoring device 40 is a pressure gauge.

[0044] Optionally, the gas injection assembly 20 includes a gas storage bottle in which inert gas is stored, and the other end of the first pipeline is connected to the gas storage bottle.

[0045] As the inert gas is introduced, the air pressure in the gas cylinder decreases, while the air pressure in the isolation space 11 gradually increases. When the air pressure in the isolation space 11 is greater than the air pressure in the gas cylinder, gas backflow occurs, that is, the gas in the isolation space 11 flows to the gas cylinder.

[0046] For this purpose, the first pipeline is provided with a one-way valve, which only allows the inert gas to pass from the first pipeline into the isolation space 11. In this way, the environment in the gas storage cylinder is kept clean.

[0047] Optionally, the gas injection assembly 20 further includes an air pump, which is installed in the first pipeline and is used to pass the gas in the first pipeline into the isolation space 11. When the air pump is turned on, the gas flow can be accelerated, so that the inert gas can be passed into the isolation space 11 faster.

[0048] Optionally, the second pipe 31 can be selectively connected to any one of the second air pipe head 35 and the blind flange 36. Specifically, when the second pipe 31 is required to connect the indoor and outdoor environments of the isolation space 11, the second pipe 31 is connected to the second air pipe head 35; when the second pipe 31 is required to block the connection between the indoor and outdoor environments of the isolation space 11, the second pipe 31 is fixed to the blind flange 36, and the blind flange 36 can block the second pipe 31 to prevent gas circulation.

[0049] Optionally, the ventilation assembly further includes a fourth pipe 37, which is inserted in the isolation space 11 and can selectively connect the indoor and outdoor environments of the isolation space 11, and a fan is installed in the fourth pipe 37. Specifically, when the staff needs to enter the methanol isolation cabin, the gas injection assembly 20 is closed, the fourth pipe 37 is opened and the fan is started, and the second pipe 31 and the third pipe 32 are opened, so that the second pipe 31 and the third pipe 32 are connected to the indoor and outdoor environments of the isolation space 11, and the fan can draw outdoor air into the isolation space 11, and the air in the isolation space 11 can be discharged from the second pipe 31 and / or the third pipe 32, so as to accelerate the gas circulation in the isolation space 11.

[0050] Optionally, the housing 10 is provided with a manhole, and the manhole is provided with a door structure. The manhole is used for workers to enter and exit the methanol isolation cabin, and the door structure is used to open or close the manhole.

[0051] Specifically, the door structure is rotatably connected to the shell 10, and the peripheral side of the door structure can overlap and abut against the shell 10 to close the manhole.

[0052] A ship is also provided, comprising the above-mentioned methanol isolation cabin.

[0053] In addition, the above are only preferred embodiments of the present invention and the technical principles used.
