Abstract

The invention discloses a liquid cargo tank anti-leakage device for a large oil tanker. The liquid cargo tank anti-leakage device for the large oil tanker comprises a liquid cargo tank; a liquid cargo tank room is arranged in the liquid cargo tank, and the liquid cargo tank room is composed of a liquid storage tank, a liquid regulating box and an empty cavity chamber; a liquid separating valve is arranged between the liquid storage tank and the liquid regulating box, and the liquid separating valve is connected with the liquid storage tank and the liquid regulating box correspondingly through an infusion pipe; the inner part of the liquid storage tank is divided into a gas phase layer and a liquid phase layer; a protective cabin is arranged between the liquid cargo tank and the liquid cargo tank room; pressure sensors are arranged in the gas phase layer, the empty cavity chamber, the protective cabin and the liquid regulating box correspondingly and are connected with each control device through branch pipes, and finally connected with a pressure real-time display device; and the pressure real-time display device is connected with a gas transmission device through a main pipe, and the gas transmission device is connected with an inert gas generating device through a main pipe. The liquid cargo tank anti-leakage device for a large oil tanker has the advantages of being reasonable in structure and firmer, safer in the tanker body structure, better preventing leakage and safer.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to an anti-leakage device for a liquid cargo tank of a large oil tanker. Background technique [0002] Oil tankers will die due to accidents such as rocking, collision and grounding during the voyage, and the resulting oil spill at sea is a major risk in the shipping process. Oil spill incidents caused by oil tanker accidents continue one after another, and all or part of the contained oil flows into the ocean. This is the most concerned and researched source of marine oil pollution at present. Coupled with the rapid development of the shipping industry, this pollution risk has gradually intensified. Therefore, it is of great practical significance to pay attention to the problem of oil spills at sea and to develop a leakage control system for the leakage of liquid cargo tanks at sea in order to reduce the risk of tanker transportation. [0003] Liquid cargo tanks include ships, off...
