Problems solved by technology
[0004] However, since the temperature of natural gas is about minus 160 degrees when it is in a liquid state, it needs to absorb heat to achieve the corresponding vaporization during the vaporization process, and the existing fishing boats need to carry tons of ice when they go fishing To store the fish in the later stage, and then increase the load of the fishing boat, and also cause the problem of high freezing cost of the fish

The invention provides a marine natural gas cylinder utilizing LNG vaporizing refrigerating and a gas supply mechanism thereof. The marine natural gas cylinder comprises a supporting frame, wherein a gas cylinder outlet liquid connecting joint is arranged at one end below the supporting frame; the gas cylinder outlet liquid connecting joint is correspondingly connected to a first connecting tube; the first connecting tube is detachably connected with a vaporizer; a spiral tube is arranged in the vaporizer; one end of the spiral tube is detachably connected to the first connecting tube, and the other end of the spiral tube is detachably connected to a second connecting tube; the second connecting tube is detachably connected to a gas-liquid conversion unit which is detachably connected to a buffer tank correspondingly; an anti-freezing liquid outlet is formed in the lower portion of the vaporizer; the anti-freezing liquid outlet is detachably connected to a first hose; the first hose is detachably connected to a marine freezing box; the other end of the corresponding marine freezing box is correspondingly connected to a pump; the pump is detachably connected to an anti-freezing liquid return hole; and the anti-freezing liquid return hole is detachably connected to the vaporizer through a connector. The marine natural gas cylinder utilizes LNG vaporizing refrigerating to realize anti-freezing liquid cooling, and a fish warehouse is cooled in a circulating mode by anti-freezing liquid via the pump.
Description
technical field [0001] The invention relates to the technical field of LNG cylinders, and mainly relates to a marine natural gas cylinder and a gas supply mechanism utilizing LNG vaporization and refrigeration. Background technique [0002] LNG is the abbreviation of liquefied natural gas (liquefied natural gas). The main component is methane. LNG is colorless, odorless, non-toxic and non-corrosive, its volume is about 1 / 625 of the same volume of gaseous natural gas, the weight of LNG is only about 45% of the same volume of water, and its calorific value is 52MMBtu / t (1MMBtu=2.52 ×10^8cal). [0003] In the current process of using liquefied natural gas on board, it is first necessary to introduce natural gas into a vaporizer for vaporization treatment, and then export the vaporized natural gas for use. [0004] However, since the temperature of natural gas is about minus 160 degrees when it is in a liquid state, it needs to absorb heat to achieve the corresponding vaporiz...
