Embodiment Construction

[0018] figure 1 Shown is a schematic structural view of the piston-type self-balancing oil-water replacement oil storage tank of the present invention. The oil storage tank is mainly composed of tank body 4, isolation device 6, head 2, reinforcement ring 5, oil storage side valve group 1, replacement water side valve group 8, air release valve 3 arranged on the side of the oil storage tank, arrangement It is composed of equipment such as the air release valve 7 on the water side of the replacement cabin. The tank body 4 divides the oil storage tank into two independent storage spaces that can be changed in real time through an isolation device 6, that is, the oil storage tank and the replacement water tank. A mechanical seal is set between the isolation device 6 and the inner wall of the tank body 4 Components for isolating fuel and displacing water.

[0019] The tank body 4 is a cylindrical structure, and the cross section is generally circular, and can also be oval, semici...

Abstract

The invention discloses a piston type self-balancing oil-water substitution oil storage tank. The piston type self-balancing oil-water substitution oil storage tank comprises a tank body of a tubular structure and a valve group arranged on the tank body. The piston type self-balancing oil-water substitution oil storage tank is characterized in that a movable piston type isolating device is arranged inside the tank body and divides the oil storage tank into two mutually-independent size-variable spaces used for storing fuel oil and substitution water respectively; the isolating device comprises a body and a mechanical seal assembly, wherein the body is matched with an inner cavity structure of the tank body, and the seal assembly is used for isolating the fuel oil and the substitution water on the two sides of the isolating device. The piston type self-balancing oil-water substitution oil storage tank has the advantages that the system structure is simple and compact, the self-balancing property is good, contamination to the fuel oil is low in the oil-water substitution process, economy is good, and reliability is high, and is quite suitable for a ship which needs to carry a large amount of fuel oil but has limited overall space.

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 main components of the ship, especially the ocean-going ship needs to carry a large amount of fuel. During the voyage, the fuel consumption will make the whole ship unbalanced. In order to eliminate the hull imbalance caused by fuel consumption, generally Ballast water systems are designed into ship systems. The traditional ballast water system is mostly independent of the fuel tank, that is, the fuel tank and the ballast water tank are not shared. This arrangement has a simple structure and does not require an oil-water separation device, but it takes up a lot of space on the ship. In recent years, in order to make full use of the effective space of the ship, it is required that the fuel oil tank can realize self-balancing, so some co...
