Abstract

The invention relates to a venting system for a liquid tank of a ship. A first venting box and a second venting box are separately arranged in a forecastle deck cabin of the ship, and are provided with baffles for dividing inner cavities into upper cavities and lower cavities; a first lubricating oil venting pipe, a second lubricating oil venting pipe and a first engine inner cavity venting pipe are connected with the upper cavity, provided with a first venting opening, of the first venting box; a first fuel oil venting pipe is connected with the lower cavity, provided with a second venting opening, of the first venting box; a third lubricating oil venting pipe, a fourth lubricating oil venting pipe and a second engine inner cavity venting pipe are connected with the upper cavity, provided with a third venting opening, of the second venting box; and a second fuel oil venting pipe is connected with the lower cavity, provided with a fourth venting opening, of the second venting box. Venting outlets of the liquid tank of the ship are arranged in a concentrated manner, so that diffusion everywhere of oil is avoided, oil gases can be collected in a concentrated manner, the mutual movement of different types of oil gases is avoided, and the space for occupying a deck is reduced.

Description

technical field [0001] The invention relates to the technical field of ship pipelines, in particular to a ship liquid tank ventilation system. Background technique [0002] The ship pipeline system is an indispensable part of the ship. The ship tank ventilation pipeline is a part of the ship pipeline system. The ship tank ventilation generally needs to pass through the deck surface to lead to the atmosphere. For fuel oil and lubricating oil, the deck is breathable and contains oil mist. If it is not handled properly, it will become a source of pollution to the ship and the marine environment. The spread of oil will pollute the ship and affect the safety of the crew. For this reason, the ventilation pipes for fuel and lubricating oil are usually directly led above the upper deck, and the oil tank is made of steel plates. There is inevitably dirty oil around the oil tank, and the oil in the oil tank needs to be cleaned regularly; even if the closed oil tank is collected throug...
