Self balancing composite tank oil and water substitution oil storage device

Abstract

The invention discloses a self balancing composite tank oil and water substitution oil storage device. The self balancing composite tank oil and water substitution oil storage device comprises a tank and a valve group arranged on the tank, wherein the tank is composed of an inner tank and an outer tank, the outer tank is a rigid tank of tube structure, two ends of the outer tank are provided with openings, the openings are sealed through shell covers, the inner thank is a flexible tank, the inner tank is arranged in the outer tank, one end of the flexible tank is open, the open end of the flexible tank overlaps one open end of the rigid tank, the edge of the open end of the flexible tank is pressed against the open end of the outer tank, which overlaps the open end of the flexible tank, through the corresponding shell cover so as to form a seal structure, and therefore the interior of the composite tank is divided into two spaces which seal each other, and fuel oil can be selected and stored in the storage space A or the storage space B according to features of fuel oil or substitute water which is stored. The self balancing composite tank oil and water substitution oil storage device has the advantages of being compact and reliable in system structure, simple in running, good in self balancing, good in economical efficiency, high in reliability, and suitably used on ships where a large amount of the fuel oil needs to be carried and overall space is limited, and causes no pollution to the fuel oil during the oil and water substitution process.

Description

technical field [0001] The invention relates to the field of ships and ocean engineering, in particular to the field of design of fuel oil storage tanks of ships and ocean engineering. Background technique [0002] The fuel tank is one of the key parts in the overall design of the ship. Especially ocean-going ships need to carry a large amount of fuel. During the voyage, as the fuel is consumed, the entire ship will be unbalanced. In order to eliminate the imbalance of the hull caused by fuel consumption, ballast water systems are generally designed in the ship system. The traditional ballast water system and the fuel tank are mostly independent, which occupies the effective space of the ship. In recent years, in order to make full use of the cabin space of the ship, increasingly stringent requirements have been put forward for the self-balancing of the fuel tank. The fuel tank technology has gradually developed, that is, the fuel tank is composed of multiple separate sub-f...
