Abstract

The invention discloses an LNG storage and supply device. The LNG storage and supply device comprises a skid-mounted seat, a storage tank, a pressurizer, a pressurizing pipeline, a gasifier, a using liquid pipeline and a liquid inlet pipeline, wherein the storage tank is fixedly arranged on the skid-mounted seat and is used for storing the liquefied natural gas; the pressurizer is fixedly arranged on the skid-mounted seat, is used for increasing pressure of the liquefied natural gas and comprises a pressurization inlet and a pressurization outlet; the pressurizing pipeline is communicated with the storage tank and the pressurization inlet and is communicated with the storage tank and the pressurization outlet; the gasifier is fixedly arranged on the skid-mounted seat, is used for gasifying the liquefied natural gas and comprises a gasification inlet and a gasification outlet; the using liquid pipeline is communicated with the storage tank and the gasification inlet; and the liquid inlet pipeline is communicated with the storage tank, so that the liquefied natural gas is injected into the storage tank.

Description

technical field [0001] The invention relates to the technical field of natural gas storage and gas supply, in particular to an LNG storage and gas supply device. Background technique [0002] The economic and environmental advantages of LNG (Liquefied Natural Gas) fuel are promoting the rapid development of LNG fuel-powered ship technology. LNG fuel-powered ship technology refers to ships using LNG fuel power plant or LNG and fuel oil mixed dual-fuel power plant technology, which improves the economy and environmental protection of ship operation compared with fuel oil power plant. Since LNG needs to be kept in a low-temperature environment for storage and supplied at room temperature, the LNG storage and gas supply device has become one of the key technologies for LNG fuel-powered ships. [0003] The LNG storage and gas supply device in the prior art includes steel cylinders connected in series through pipelines, low-temperature valves, hot water vaporizers, pressure gauge...
