Mini cryogenic lng storage tank

Abstract

The invention belongs to the technical field of pressure vessels, and particularly relates to a mini low-temperature LNG storage tank. The mini low-temperature LNG storage tank comprises a tank body,a supporting seat, a liquid outlet, a driving unit, a lifting unit and a starting and stopping unit, wherein the tank body is of a Y-shaped structure, the supporting seat is arranged at the bottom ofthe tank body, and the supporting seat is used for supporting the tank body; the liquid outlet is formed in the bottom of the side surface of the tank body, and the liquid outlet is used for filling or flowing out of low-temperature LNG; the lifting unit is arranged in the tank body, and the lifting unit is used for accelerating the low-temperature LNG flowing speed; the driving unit is arranged in the center of the supporting seat, and the driving unit is used for driving the lifting unit to move; and the starting and stopping unit is arranged between the lifting unit and the tank body, and the starting and stopping unit is used for starting and stopping the lifting unit. Through cooperation between the tank body, the supporting seat, the liquid outlet, the driving unit, the lifting unitand the starting and stopping unit, the low-temperature LNG flowing speed can be improved, the storage cost can be reduced, and LNG residues in the tank can be reduced.

Description

technical field [0001] The invention belongs to the technical field of pressure vessels, in particular to a miniature low-temperature LNG storage tank. Background technique [0002] A pressure vessel refers to a closed device that holds gas or liquid and carries a certain pressure. A pressure vessel is a closed container that can withstand pressure. A pressure vessel has a wide range of uses. All fields have an important position and role; Among them, the most used in the chemical industry and petrochemical industry, the pressure vessels used in the petrochemical industry alone account for about 50% of the total number of pressure vessels; pressure vessels in the chemical industry and petrochemical industry Lingcheng, mainly used for heat transfer, mass transfer, reaction and other processes, as well as storage and transportation of pressurized gas or liquefied gas; it is also widely used in other industrial and civil fields, such as air compressors; various special compress...
