Description
Technical field
A kind of marine fuel tank is the utility model is related to, specifically a kind of fuel tank case of the LNG ship with replacement function
System.
Background technology
Low-carbon has become the developing direction of following global shipping business, natural in face of environmental protection and pressure of competition, liquefaction
Gas is increasingly subject to the concern and favor of shipping business as emerging power fuel peculiar to vessel.At present, liquefied natural gas (LNG) power ship has been
Successful through increasing area at home and abroad, the paces of popularization are expected to accelerate, the liquefied natural gas compared with conventional crude oil
There is small volume as marine fuel, calorific value is high, reserves are big, supply foot, discharge is low, pollution is small, easy transport, it is safer and into
This low and market stability advantage.Existing LNG ship fuel tank system, mostly based on fixed sleeping tank, a small amount of use can
Mobile horizontal tank.Due to sleeping tank volume is big, from it is great, be not easy that quick bolt is solid, lifting, typically marine fuel tank fill letting out
During liquid, using LNG ship oceangoing ship bank base filling station, landing stage or the mobile hose type filling arm docking marine fuel tank filling for filling ship.
Regardless of whether it is that all there is docking is difficult, pipeline is long, liquid source wastes to the tank topping up that crouched on ship from landing stage or bank base station
Greatly, the problems such as topping up time is long.
Utility model content
The purpose of this utility model is to provide a kind of LNG ship with replacement function fuel tank case system, to solve
The problem of being proposed in above-mentioned background technology.
To achieve the above object, the utility model provides following technical scheme：
A kind of LNG ship with replacement function fuel tank case system, including hull, it is provided with the stern of the hull
Tank case and ice chest, the tank case include tank case A and tank case B；Tank case A and tank case B respectively uses pipeline with topping up pipeline, liquid
Connected with supercharging drain pipe line, supercharging vapor return line one end connection topping up pipeline, other end connection vaporizer, be pressurized vapor return line
Switch valve is installed between vaporizer；Liquid is connected using pipeline and supercharging drain pipe line with vaporizer；Vaporizer is connected with
Circulation water inlet pipe and recycling outlet；Vaporizer connects surge tank by gas using pipeline；Vaporizer and surge tank are respectively positioned on
In ice chest.
As further program of the utility model：The corner fittings of the tank case is fixed aboard ship by quick Shuan Gu mechanisms.
Compared with prior art, the beneficial effects of the utility model are：The utility model is designed reasonably so that marine fuel
Tank have it is removable, replacing it is convenient fill characteristic, during LNG ship oceangoing ship supplement LNG fuel, in existing container handling harbour
Carry out, and be provided simultaneously with the function of flexible pipe conveying fueling；Slack tank case is unloaded, and canful case is lifted to LNG ship oceangoing ship precalculated position,
It is very convenient to replace, and greatly shortens the fueling time, reduces losses of the LNG in filling process, when tank case breaks down,
Replaceable tank case is repaired, and does not influence the normal operation of ship, and LNG ship can also be made by the use of fuel tank case as common LNG tank case
With, improve its turnover, efficiency of operation.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 3, a kind of LNG ship with replacement function fuel tank case system, including hull 1, the hull 1
Stern at tank case 2 and ice chest 3 are installed, the tank case 2 includes tank case A21 and tank case B22；Tank case A21 and tank case B22 divide equally
It is not connected with topping up pipeline 7, liquid using pipeline 4 and supercharging drain pipe line 5, supercharging vapor return line 6 one end connection topping up pipeline
7, the other end connects vaporizer 8, and switch valve is provided between the supercharging vaporizer 8 of vapor return line 6；Liquid uses pipeline 4 and supercharging
Drain pipe line 5 is connected with vaporizer 8；Vaporizer 8 is connected with circulation water inlet pipe and recycling outlet；Vaporizer 8 passes through gas
Surge tank 10 is connected using pipeline 9；Vaporizer 8 and surge tank 10 are respectively positioned in ice chest 3.
Further, the corner fittings of tank case 2 described in the utility model is fixed aboard ship by quick Shuan Gu mechanisms so that tank case
It is applied to whole LNG ship with the fuel tank decorum as a moveable standalone module.
Horizontal tank is replaced with tank case by the utility model, and designs tank case pipe-line system and rear end marine fuel pipeline system
