SEALED AND HEAT-INSULATING TANK CONTAINING ANTI-CONVECTION FILLING ELEMENTS Russian patent published in 2024 - IPC F17C3/02 F17C13/00 B63B25/10 

FIELD: gas industry.

SUBSTANCE: group of inventions relates to reservoir (71) for storage of liquefied gas. At that, reservoir (71) includes peripheral walls (1), which include sealing membrane and one heat-insulating barrier. Sealing membrane includes corrugated metal plates containing first rows of parallel corrugations extended in direction x, and second rows of parallel corrugations extended in direction y. Direction x is the direction of greater inclination. Peripheral walls (1) contain filling elements with pressure drop, which are located in corrugations of the first rows of corrugations so that to form belt (16) of filling elements extended along perimeter of reservoir (71). Belt is formed by one overlapping part (17) and one intermittent part (18) and includes not more than one interrupting part (18) per peripheral wall (1).

EFFECT: reduced convection or thermal siphon in corrugations of sealed and heat-insulating reservoir.
