Abstract

The invention provides a ventilating overflow device and a ship and relates to the technical field of ships. The ventilating overflow device is used for being arranged on a fuel tank and overflow tanks and comprises ventilation pipes, overflow pipes and one-way flow pieces. The ventilation pipes are arranged on the fuel tank and used for ventilating the fuel tank and the outer side; the fuel tankcommunicates with the overflow tanks through the overflow pipes, and when fuel in the fuel tank overflows, the fuel can flow into the overflow tanks through the overflow pipes; and the highest pointsof the overflow pipes are located below the top ends of the ventilation pipes, the one-way flow pieces are arranged on the overflow pipes, and the fuel can flow to the overflow tanks from the fuel tank. The one-way flow pieces are arranged on the overflow pipes, so that the highest points of the overflow pipes do not need to be higher than a freeboard deck or the height required by a damaged stability calculation result, even though the dynamic pressure generated by on-way resistance exists when an overflowing phenomenon happens, the static pressure of the fuel tank is lower than that of a traditional open or closed ventilating overflow system, so that the design pressure of the fuel tank is lowered, and the structural weight of the fuel tank is reduced.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a breathable overflow device and a ship with the breathable overflow device. Background technique [0002] The purpose of installing a venting system on the fuel oil tank of a ship is to avoid the overpressure or negative pressure generated in the fuel tank when filling or pumping fuel oil, which exceeds the range that the fuel tank structure can withstand, resulting in damage to the fuel tank. When filling fuel into the fuel tank, due to the high pressure pumped by the power unit, the fuel tank will be over-pressurized once the air and the filled fuel have no time to discharge or nowhere to discharge; and when pumping fuel, if If there is no good ventilation between the fuel tank and the outside world, a large negative pressure will be formed in the fuel tank. [0003] Traditional open ventilation systems such as figure 1 As shown, the vent pipe 1' is arranged on the top of the ...
