It is below in conjunction with the accompanying drawings and specific real to make those skilled in the art be better understood from the technical solution of the utility model
Example is applied to elaborate to the utility model.
The present embodiment provides a kind of LNG low-temperature liquid storage tanks, and as depicted in figs. 1 and 2, it includes tank body 1, base 2, control cabinet
10 and tank external circulating device, tank body 1 be cavity filling insulation material between horizontal double-layer stainless steel storage tank, double-layer stainless steel simultaneously
Vacuumize；The bottom of tank body 1 is provided with base 2；The bottom of tank body 1 is provided with liquefied gas outlet 3, and the top of tank body 1 is inclined provided with one
Oblique gas outlet 4, gas outlet 4 connects baffle-box 7 by flue 6, and baffle-box 7 connects the inlet end of compressor 8 by pipeline,
The outlet end of compressor 8 connects one end of return duct 9, and the other end of return duct 9 is deep into tank body 1；Flue 6 is provided with pressure
Force regulating valve 5, the return duct 9 positioned at the outside of tank body 1 is coated with insulation material；Control cabinet 10 is located at the outside of tank body 1, including
Housing, PLC 13 and display screen 14, PLC 13 are arranged on enclosure interior, and display screen 14 is arranged on hull outside；
PLC 13 connects the temperature sensor 11 and pressure sensor 12 that are located in tank body 1, PLC 13 by signal wire
Connect display screen 14.
In the present embodiment, the insulation material that tank body 1 is filled is expanded perlite, with good insulation cold insulation performance, is matched somebody with somebody
