Embodiment Construction

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as a limitation of the present invention.

[0024] The embodiments of the present invention will be described below based on the overall structure of the present invention.

[0025] A dual-fuel large container ship LNG fuel tank, such as Figure 1-3 As shown, it includes an upper fixing frame 1 and a lower fixing frame 2. The upper fixing frame 1 and the lower fixing frame 2 are detachable buckle installation or bolt-fixed installation, and any structure that can achieve the corresponding fixing effect can be used. The lower fixing frame 2 A tank body 3 is arranged on the inner wall of the upper fixing...

Abstract

The invention discloses a dual-fuel large container marine LNG fuel tank, and relates to the field of LNG fuel tanks, the dual-fuel large container marine LNG fuel tank comprises an upper fixing frame and a lower fixing frame, the upper fixing frame and the lower fixing frame are detachably installed in a buckled mode, a tank body is arranged on the inner wall of the lower fixing frame, and a fixing seat is arranged on the inner wall of the upper fixing frame and the inner wall of the lower fixing frame in a connected mode. The tank body is placed between the upper fixing frame and the lower fixing frame, the weight of the tank body is borne by the spring steel plate and the lower fixing frame, the spring steel plate can achieve a certain damping effect in the bearing process, and furthermore, a plurality of damping mechanisms are arranged between the upper fixing frame and the lower fixing frame, so that the damping effect is improved. And the damping mechanism is composed of a spring, a fixed shell and a movable rod, the spring can effectively buffer the vibration force on the side face of the tank body, multiple damping of the tank body is achieved through cooperation with a spring steel plate, and the vibration force generated to the tank body in the movement process of the container ship is reduced.

Description

technical field [0001] The invention relates to the field of LNG fuel tanks, in particular to a dual-fuel large container ship LNG fuel tank. Background technique [0002] Liquefied natural gas, referred to as LNG, is mainly composed of methane. It is recognized as the cleanest fossil energy on earth. It is colorless, odorless, non-toxic and non-corrosive. Its volume is about 1 / 625 of the volume of the same amount of gaseous natural gas. Its quality is only about 45% of the same volume of water. The manufacturing process is to first purify the natural gas produced by the gas field, and then transport it by LNG ships after a series of ultra-low temperature liquefaction. The combustion of liquefied natural gas has very little air pollution and emits a large amount of heat, so liquefied natural gas is a relatively advanced energy source. [0003] Dual-fuel large container ships generally use LNG fuel tanks as energy supply mechanisms, that is, to replace traditional oil energy...
