Abstract

La présente invention concerne le domaine de la conception de réservoirs et peut s'utiliser pour ériger des réservoirs pour le stockage de fractions légères d'hydrocarbures et principalement pour le stockage des essences. Le réservoir de stockage d'hydrocarbures est constitué d'un corps, d'un toit et d'un revêtement de protection flottant constitué de plusieurs éléments flottants sous la forme de corps de révolution ayant une forme identique. Dans le réservoir, une partie des éléments flottants du revêtement de protection se situent en dessous du plan de liquide et une autre partie se trouvent dans la partie gaz du réservoir. Le trait distinctif de l'invention est la présence d'éléments flottants ayant une forme et des dimensions qui diffèrent de 5 % au maximum. Les éléments flottants dont est constitué le revêtement de protection flottant possèdent un centre de gravité décalé par rapport à leur centre géométrique. Tous les éléments du revêtement de protection sont réalisés en métal non étincelant. Le résultat technique consiste en une baisse de la vitesse d'évaporation et de concentration des vapeurs de liquide ; une flegmatisation du processus de combustion et élimination de la probabilité d'accumulation d'une charge statique et d'apparition d'un étincellement entre les éléments flottants. -
