FIRE EXTINGGUISHING SYSTEM OF SHIP USING CARBON DIOXIDE

摘要

The present invention relates to an internal fire extinguishing system of a ship to perform oil fire fighting and to prevent secondary equipment damage by applying a thermal oil boiler and an economizer fire extinguishing system using carbon dioxide as a fire extinguishing agent in place of a prior water spraying fire extinguishing system using clean water. Suggested is the internal fire extinguishing system of the ship, including an engine room comprising: a fire extinguisher tank where carbon dioxide powder or solution capable of being sprayed during fire breakout is stored; a main control valve to control the sprayed carbon dioxide powder or solution finally while being connected to a pipeline of the fire extinguisher tank; and a safety valve to discharge high pressure of the fire extinguisher tank out of the tank when the high pressure occurs in the fire extinguisher tank; an economizer which is connected to the engine room, and heats the thermal oil up to a required temperature using an exhaust gas as a heat source; a thermal oil boiler which is connected to the engine room, and heats the thermal oil up to the required temperature using a heat source generated by burning the thermal oil; a fire detector which is installed at each of the economizer and the thermal oil boiler, and detects fire breakout of facilities; a subsidiary control valve which is connected to the pipeline of the economizer and the thermal oil boiler respectively, and opens a corresponding valve in case a fire is detected from the fire detector; and a control part which controls the main control valve and the subsidiary control valve collectively, and opens or closes a valve of the carbon dioxide powder or solution sprayed locally.
