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.

Embodiment 1

[0023]Example 1: A breathable mast suitable for FSRU (see attachedfigure 1 , AttachedFigure 4), including a mast body 2 installed on the hull 1, a breathable cap 3 installed on the upper end of the mast body, the mast body has a tubular structure, and the mast body is provided with a gas sampling port 4, a liquid tank safety valve outlet pipe interface 5, and a liquid tank The steam release pipeline interface 6, the gas-water separator outlet pipe interface 7, the portable connection end interface 8, the nitrogen flushing pipeline interface 9, the drain pipe interface 10, and the liquid tank safety valve outlet pipe interface are provided with four. The gas sampling port, the liquid tank safety valve outlet pipe interface, the liquid tank vapor release pipe interface, the gas-water separator outlet pipe interface, the portable connection end interface, the nitrogen flushing pipe interface, and the drain pipe interface are arranged in order from top to bottom. The outer wall of the m...

Embodiment 2

[0026]Example 2: A breathable mast suitable for FSRU (see attachedfigure 2 , Attachedimage 3 ), its structure is similar to embodiment 1, the main difference is that in this embodiment the breathable cap includes a connecting section 25, an air outlet section 26, an arc-shaped transition section 27 arranged between the connecting section and the air outlet section, and the exhaust blades are placed In the connecting section, the rotating shaft is rotatably installed on the transition section, and the push plug 28 that can move up and down is installed in the air outlet section. A number of support protrusions 29 are provided under the push plug on the inner wall of the air outlet section. A long strip of air outlet slot 30, push the plug to install the indicator rod 31, the indicator rod is green, yellow, and red from top to bottom. The upper end of the air outlet section is connected with a rain cap 32. The rain cap covers the air outlet section to prevent rain An air outlet gap is...

Abstract

The invention discloses a breathable mast suitable for an FSRU and aims to overcome the defect that an exhaust emission device is inconvenient to arrange in the working process of the FSRU. The mast comprises a mast body installed on a ship body and a ventilation cap installed at the upper end of the mast body, and the mast body is of a tubular structure. A gas sampling port, a liquid tank safetyvalve outlet pipe connector, a liquid tank steam release pipeline connector, a gas-water separator outlet pipe connector, a portable connecting end connector, a nitrogen flushing pipeline connector and a drain pipe connector are arranged on the mast body, and a liquid accumulation disc is connected to the outer wall of the mast body and is close to the lower part of the drain pipe connector; a rotating shaft is installed in the ventilation cap, the upper end of the rotating shaft extends out of the ventilation cap, a plurality of bowl-shaped wind-driven bowls are evenly distributed and connected to the upper end of the rotating shaft, openings of the wind-driven bowls are arranged clockwise or anticlockwise, and a plurality of air draft blades are evenly distributed and installed 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 work 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 board.Summary of the invention[0003]The invention overcomes the inconvenience of the exhaust gas discharge d...
