Security system capable of inhibiting abnormal release of CO2 in ships and operating method

Abstract

The embodiment of the invention discloses a security system capable of inhibiting abnormal release of CO2 in ships and an operating method. The security system comprises a collecting pipe, a CO2 release pipe, a CO2 release branch pipe, and a first safety pipe, wherein the collecting pipe communicates with a plurality of CO2 gas bottles; the CO2 release pipe communicates with the collecting pipe, and a main release valve is arranged on the CO2 release pipe; the CO2 release branch pipe which is arranged in a risk-avoiding place and communicates with the carbon dioxide release pipe through the main release valve, and a manual release cut-off valve for controlling entrance of the CO2 in the CO2 release pipe into the CO2 release branch pipe is arranged on a part, being located in the risk-avoiding place, of the CO2 release branch pipe; one end of the first safety pipe is arranged between the collecting pipe and the CO2 release pipe while the other end of the first safety pipe is arranged outside an open deck; a first safety valve is arranged on the first safety pipe; and CO2 in the pipeline is exhausted to the open deck through the first safety valve when the pressure of the CO2 in thepipeline of the safety system exceeds a safe threshold value, so that the life threats of crews in the risk-avoiding place can be prevented from malicious release of the CO2.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a method for preventing ship CO 2 Safety system and method of operation for abnormal release. Background technique [0002] In order to reduce the threat of pirates to the lives of crew members on some international shipping routes, some ships are now remodeled or built with special safety cabins as the crew's refuge. When there is no safety cabin, the engine room can also be used as the last bastion of the crew. If the pirates cannot be prevented from boarding the ship, all crew members should evacuate into the safety cabin or evacuate into the engine room through the chimney door behind the bridge, and lock all the doors leading to the engine room from the inside to gain time for rescue. [0003] The engine room of conventional sea-going ships adopts CO as a whole 2 Fire extinguishing, CO 2 The room is arranged outside the cabin. CO to cabin 2 The release main valve on the m...

AI Technical Summary

Problems solved by technology

[0005] The existing technical scheme does not take into account the requirements of anti-piracy, there is no safety valve for hedging and a manual shut-off valve for release, if pirates occupy the CO 2 room or fire control station, by releasing CO 2 To endanger the life safety of persons in the safe-haven place
