Abstract

The invention discloses an ice melting pipeline and method for a water falling opening of an LNG ship in an ice area, and the pipeline comprises a water falling pipe which is connected between the deck outfall and a broadside water outlet, and an ice melting pipeline which is connected with the downpipe and a ship steam pipeline respectively, the ice melting pipeline is provided with a control valve used for controlling switching of a normal water falling mode and an ice melting mode so that normal liquid seawater at the water falling opening or seawater obtained after steam melting and conveyed through the steam pipeline at the water falling opening can be smoothly discharged to the outboard through the water falling pipe. The ice melting pipeline is connected between the downpipe and the ship steam pipeline, the ship steam serves as a dissolving medium to melt frozen seawater at the outfall, the problem that normal navigation of a ship is affected due to the fact that seawater at the outfall of a deck freezes in a low-temperature course is effectively solved, and the navigation safety of the ship is guaranteed.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to an ice-melting pipeline and method for a deck drain of an LNG ship in an ice area. Background technique [0002] When an LNG ship in an ice area is sailing in an ice area, the air is filled with white waves and droplets, which will be blown onto the deck of the ship by the wind. figure 1 However, due to the low temperature and complex sea conditions of ships in ice regions, water droplets or mist can easily freeze near the drain of the downspout. If the icing near the drain is not resolved in time, it will directly affect the normal navigation of the ship. Contents of the invention [0003] In view of this, the present invention provides an ice-melting pipeline and method for the deck drain of an LNG ship in an ice area, to solve the problem that the seawater at the deck drain will freeze during low-temperature routes and affect the normal navigation of the ship. [0004]...
