Description
Technical field
The utility model belongs to LNG cargo ship building technologies field, and in particular to a kind of LNG transports cabin bottom is released and is
System.
Background technology
《MSC.93-IGC Code》The part Article 3 of 3rd chapter 7 define A type tanks secondary shielding and goods tank field domain in set
Bilge bleed-off system is put, the leakage and breakage of goods tank, but not which kind of mode of specific requirement prevented.
Current LNG cargo ships（Such as Type A types）When building, directly secondary shielding is wrapped on goods tank, goods tank is received
Temperature influence deformation, the sealing between secondary shielding and goods tank is difficult to control, and the LNG of leakage cannot be excluded in time, make cargo ship
In the presence of certain potential safety hazard.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of LNG transports cabin bottom bleed-off system, and this is released and is
System simple structure, is easy to arrangement, can in time exclude the LNG of leakage, improves the security of cargo ship.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of LNG transports cabin bottom bleed-off system, including is arranged on the LNG goods tanks in hull, between LNG goods tank and hull
Time screen layer is provided with, space is left between secondary screen layer and LNG goods tanks, the bottom in space is provided with liquid-level switch, indulged on LNG goods tanks
To feed tube, discharging tube and medium tube is provided with, the interior bottom that time screen layer, bottom extend to LNG goods tanks is run through at the top of feed tube
Portion, the top of discharging tube runs through time screen layer, bottom and is provided with jet pump, and the suction inlet of jet pump bottom is provided with pipette, imbibition
Pipe is placed in space, and the top of medium tube is run through time screen layer, bottom and is connected with the medium inlet of jet pump side by bend pipe.
The bottom of the discharging tube and medium tube is provided with c-type breeze way.
Seal is provided between the feed tube, discharging tube and medium tube and secondary screen layer.
The side of the hull top is provided with to overhaul the access opening in space.
The utility model has the advantages that：Bleed-off system simple structure of the present utility model, is easy to arrangement, can exclude in time
The LNG of leakage, improves the security of cargo ship.

Specific embodiment：
As depicted in figs. 1 and 2, a kind of LNG transports cabin bottom bleed-off system, including the LNG goods tank 3 in hull 1 is arranged on,
Time screen layer 2 is provided between LNG goods tank 3 and hull 1, space is left between secondary screen layer 2 and LNG goods tank 3, the bottom in space sets
There is liquid-level switch 9, feed tube 4, discharging tube 5 and medium tube 6 are longitudinally provided with LNG goods tank 3, the top of feed tube 4 is through time screen
The inner bottom part that layer 2, bottom extends to LNG goods tank 3 is covered, the top of discharging tube 5 runs through time screen layer 2, bottom and is provided with jet pump 7,
The suction inlet of the bottom of jet pump 7 is provided with pipette 8, and pipette 8 is placed in space, the top of medium tube 6 run through time screen layer 2,
Bottom is connected by bend pipe with the medium inlet of the side of jet pump 7, in order to ensure the sealing in space, by feed tube 4, discharging tube
5 and medium tube 6 be directly weldingly fixed on LNG goods tank 3, and seal is set, the top of hull 1 between three and secondary screen layer 2
Side be provided with to overhaul the access opening 11 in space.
In the utility model, LNG is stored to LNG goods tank 3 by feed tube 4, is set when leaking to the LNG in space and reaching
During fixed liquid level, liquid-level switch 9 sends alarm, and the LNG that will leak out by jet pump 7 and pipette 8 is from the row of discharging tube 5
Go out, in the process, the working fluid of jet pump 7 is transmitted by medium tube 6.
The bottom of discharging tube 5 and medium tube 6 is provided with c-type breeze way 10 so that though the bleed-off system LNG goods tank 3 because
Also can normally be run in the case of temperature deformation.
