Abstract

The invention relates to an inert gas protection device for a low-flash-point system of a marine ship. The inert gas protection device comprises a nitrogen generator and a nitrogen collector, wherein the nitrogen generator is connected with the nitrogen collector through a delivery pipeline; the nitrogen collector is connected with a booster air compressor through a delivery pipeline; a plurality of nitrogen storage cylinders are respectively connected with the booster air compressor through delivery pipelines, and are all connected with pressure reducing valve group control stations through delivery pipelines. Both pressure control valves and isolating valves are arranged on all the nitrogen storage cylinders. The inert gas protection device has the benefits that the safety of the marine ship for transporting low-flash-point substances is effectively improved; the explosion rate of the transported low-flash-point substances in marine accidents is effectively reduced; the inert gas protection device can also be used as a standby gas choice for the marine ship.

Description

technical field [0001] The invention relates to an inert gas protection device for a low flash point system of a marine engineering ship. Background technique [0002] The low-flash point substances used in the field of marine engineering require specific ships for transportation. The low-flash point substances have a high possibility of explosion and fire, and have high requirements for transportation and storage. The inert gas protection device reduces the probability of accidents and improves the safety and reliability of the transportation process by isolating the combustion accelerant among the three elements of combustion. The method of generating inert gas through boiler exhaust gas currently used on oil tankers is not suitable for use on narrow and small marine engineering ships due to the large occupation volume and poor disposal of waste. Contents of the invention [0003] The object of the present invention is to provide an inert gas protection device for a low...
