Description
Technical field
The utility model relates to LNG Technology field, particularly relates to a kind of boats and ships LNG fuel system.
Background technique
The whole world reduces discharging pushes shipping business to the teeth of the storm with low-carbon (LC) trend; " vessel pollution control international convention " relevant regulations according to IMO (International Maritime Organization) Marine Environmental Protection Committee formulates: can not more than 0.1% in the fuel used sulphur content of ECA (discharge control zone) vessel after requiring on January 1st, 2015; for this green shipping energy development trend; various energy resources research is invested in visual angle by the whole world, such as: use various bunker fuel oil to reduce Sulpher content, coal-fired purification, nuclear energy, the renewable sources of energy etc.Because LNG (LNG Liquefied natural gas) more environmental protection, the most promising method uses LNG instead fuel exactly at present.
According to the actual requirements, most LNG powered ship all establishes two natural gass to start main frame, and regulation in " gas fuel power ship specification " " if gas must be cut off because of the Leakage Gas in supply air line for seasonable, then another set of auxiliary separate fuel supply system should be had to use; If be provided with multi-engine installation, and the air supply system of every platform motor is independently arranged, then can not establish auxiliary fuel system " known, the fuel supply unit for the mono-fuel boats and ships of LNG generally need arrange two covers.
The design of supply system be in the market by filling unit and wherein a set of air supply unit be placed in same connection place, if wherein a set of unit breaks down, another set of unit will be affected so that cannot normally work; Secondly, the air supply system of some LNG powered ships does not arrange and connects place, then the exposure distance in this region can increase.
Model utility content
In view of this, the purpose of this utility model is to provide a kind of boats and ships LNG fuel system, this supply system is the one end filling piping joint of placing filling unit being arranged on separately storage tank, place the set the other end at storage tank in air feed piping joint of multiple independent gas supply unit, neither affect when air supply unit is broken down, can cooperatively interact again, ensure the independent, safe and reliable of air feed, and maintain easily maintenance.
In order to solve the problem existing for background technique, the utility model provides a kind of boats and ships LNG fuel system, comprising:
Be connected, place separately the filling piping joint institute of unit of annotating with described storage tank, be connected, place the air feed piping joint institute of air supply unit with described storage tank.
Wherein, described air supply unit communicates with the end socket of described storage tank one end.
Wherein, described air supply system comprises multiple independent gas supply unit, and each described independent gas supply unit is placed in respective described connection place.
Wherein, described filling unit communicates with the end socket of the described storage tank the other end.
Wherein, the end socket at described storage tank two ends is welded on described filling piping joint in one's power in the institute of described air feed piping joint.
Wherein, in each described connection place, detection of gas alarm is set; In each described connection place, distance base plate a distance is provided with a temperature transmitter and a liquid-level switch.
Wherein, top, each described connection place sets out air port, and bottom arranges intake grill.
Wherein, each described connection place leg adopts low temperature material, and described low temperature material is stainless steel or aluminum alloy.
Compared with prior art, illustrative embodiment of the present utility model comprises following advantage:
By place separately filling unit filling piping joint set by storage tank one end, place the set the other end at storage tank in air feed piping joint of multiple independent gas supply unit, neither interact when single air supply unit is broken down, can cooperatively interact again, ensure the independent, safe and reliable of air feed, and maintain easily maintenance.

Embodiment
The utility model provides a kind of boats and ships LNG fuel system, shows the structural representation of the boats and ships LNG fuel system in some embodiments referring now to Fig. 1, Fig. 1.
As shown in Figure 1, disclose a kind of boats and ships LNG fuel system, comprising:
Be connected, place separately the filling piping joint institute 7 of unit 8 of annotating with described storage tank 11, be connected, place the air feed piping joint institute 9 of air supply unit 10 with described storage tank 11.
LNG is filled in storage tank 11 by filling unit 8, and the gaseous natural gas that the liquid LNG in storage tank 11 is vaporized by vaporizer in air supply unit 10, heated evolves is temperature, pressure meets gas engine user demand, for motor.Being placed on all separately with air supply unit 10 by filling unit 8 is connected in place, can prevent liquid splash, dangerous region is reduced, avoids leaking the direct injury caused.
Further, described air supply unit 10 communicates with the end socket of described storage tank 11 one end.
Further, described air supply unit 10 comprises multiple independent gas supply unit, and each described independent gas supply unit 10 is placed in respective described connection place.
Further, described filling unit 8 communicates with the end socket of described storage tank 11 the other end.
Air supply unit 10 and filling unit 8 are in the two ends of storage tank 11 respectively, do not affect the use of air supply unit 10, and ensure safe and efficient when ensureing filling storage tank 11.Avoid the normal operation affecting other unit when wherein any a set of unit breaks down simultaneously.
Further, the end socket at described storage tank 11 two ends is welded in described filling piping joint institute 7 and described air feed piping joint institute 9.
