Problems solved by technology

Existing LNG filling stations use submersible pumps for unloading, filling and filling, which have disadvantages such as high investment and operating costs and low reliability
Moreover, the BOG generated in the station and in the LNG tanker cannot be effectively used, which is easy to generate waste

Abstract

The invention discloses an LNG gasification device. The device comprises a first tank car port, a second tank car port and a third tank car port; a first liquid phase outlet of an LNG tank car is connected with the first tank car port through a first unloading hose; the first tank car port is connected with a liquid inlet emergency shutoff valve through a third pipeline; the liquid inlet emergencyshutoff valve is connected with a liquid inlet port of an LNG storage tank through a fourth pipeline; and a liquid outlet port of the LNG tank car is connected with an air temperature type gasifier through a twelfth pipeline. The device has the advantages of being low in energy consumption and stable in unloading; BOG generated by self-pressurization is used in stations after being processed, sothat safety and convenience are provided; LNG is gasified through air temperature and a water bath gasifier, so that the energy consumption is low; both the liquid inlet and outlet pipelines are provided with emergency shutoff valves, so that safety and reliability are provided; and the storage tank is provided with a self-pressurization system and a low-temperature pump is not needed, so that resources are saved.

Description

technical field [0001] The invention relates to the technical field of LNG unloading, in particular to an LNG gasification device. Background technique [0002] LNG is the abbreviation of English liquefied natural gas (liquefied natural gas). The main component is methane. LNG is colorless, odorless, non-toxic and non-corrosive, and its volume is about 1 / 600 of the volume of the same amount of gaseous natural gas. Compared with gasoline, diesel and compressed natural gas (CNG), LNG has obvious advantages such as high safety, strong economy, small environmental negative effects, and high energy storage density. As a vehicle fuel, LNG is widely used in urban buses, heavy trucks and intercity buses, and the supporting LNG filling stations are also developing rapidly. Existing LNG filling stations use submersible pumps for unloading, filling and filling, which have disadvantages such as high investment and operating costs and low reliability. Moreover, the BOG generated in t...
