Problems solved by technology

[0003] The invention overcomes the inconvenient setting of the exhaust gas discharge device in the working process of the FSRU, and provides a ventilating mast suitable for the FSRU. The mast is used to discharge the exhaust gas, which increases the exhaust gas discharge height, prevents the exhaust gas from harming the crew, and at the same time discharges the exhaust gas with the help of the mast. Emission will not add extra cost, nor will it take up extra space on the ship. The exhaust gas discharge device is convenient to set up, which is conducive to the emission of exhaust gas, and the effect of exhaust gas emission is good.

Abstract

The invention discloses a ventilating mast suitable for FSRU, aiming to solve the problem of inconvenient setting of exhaust gas discharge devices during the working process of FSRU. The invention includes a mast body installed on the hull and a breathable cap installed on the upper end of the mast body. The mast body is in a tubular structure. The mast body is provided with a gas sampling port, a liquid tank safety valve outlet pipe interface, and a liquid tank vapor release pipeline interface. , the outlet pipe interface of the gas-water separator, the portable connection port, the nitrogen flushing pipeline interface, and the drainage pipe interface. The outer wall of the mast body is connected to the liquid accumulation tray below the drainage pipe interface; The upper end of the rotating shaft is evenly connected with several bowl-shaped wind-driven bowls, the openings of the wind-driven bowls are all arranged in a clockwise direction or counterclockwise, and a number of exhaust blades are evenly distributed at the lower end of the rotating shaft.

Description

Technical field [0001] The present invention relates to a marine device, and more specifically, it relates to a breathable mast suitable for FSRU. Background technique [0002] FSRU is the abbreviation of Floating Storage and Regasification Unit (English Floating Storage and Regasification Unit), also called floating regasification unit, floating LNG regasification unit, usually also called LNG-FSRU. Exhaust gas and volatile gas need to be discharged during the working process of FSRU. At present, most of these exhaust gas are discharged by direct discharge method, or a discharge pipe is installed to collect the exhaust gas and discharge it together. The exhaust gas is directly discharged, and the discharge height is low, which will cause harm to the crew. Exhaust gas is discharged through the installation of discharge pipes, which will increase equipment investment and occupy limited space on the ship. Summary of the invention [0003] The invention overcomes the inconvenience ...
