Title (EN) SEALED AND THERMALLY INSULATING TANK WITH ANTI-CONVECTIVE FILLING ELEMENT
(FR) CUVE ÉTANCHE ET THERMIQUEMENT ISOLANTE À ÉLÉMENT DE REMPLISSAGE ANTI-CONVECTIF
Abstract:
(EN) The invention relates to a sealed and thermally insulating tank for storing a fluid, wherein a tank wall comprises, in series, in the direction of the thickness, a secondary thermal insulation barrier (1), a secondary sealing membrane (4), a primary thermal insulation barrier (5) and a primary sealing membrane (7), in which the secondary sealing membrane (4) is a corrugated metal membrane comprising a series of parallel corrugations (25, 26) forming channels and planar portions located between said corrugations (25, 26), and wherein the anti-convective filling elements (16, 20, 22) are arranged in corrugations (25, 26) of the secondary sealing membrane (4) in order to create a head loss in said channels.
(FR) L'invention concerne une cuve étanche et thermiquement isolante de stockage d'un fluide, dans laquelle une paroi de cuve comporte successivement dans une direction d'épaisseur une barrière d'isolation thermique secondaire (1), une membrane d'étanchéité secondaire (4), une barrière d'isolation thermique primaire (5) et une membrane d'étanchéité primaire (7), dans laquelle la membrane d'étanchéité secondaire (4) est une membrane métallique ondulée comportant une série d'ondulations (25, 26) parallèles formant de canaux et des portions planes situées entre lesdites ondulations (25, 26), et dans laquelle des éléments de remplissage anti-convectifs (16, 20, 22) sont disposés dans des ondulations (25, 26) de la membrane d'étanchéité secondaire (4) pour créer une perte de charge dans lesdits canaux.
