Description

Combined fire extinguishing system for ship}

The present invention relates to a composite foam fire extinguishing system for ships, and more particularly, to a composite foam fire extinguishing system for ships incorporating a deck foam fire extinguishing device and a high expansion foam fire extinguishing device which are separately installed in a ship.

In general, ships handling flammable and combustible materials should not carry matches, iron fittings or other flame-prone items, or shoes with heeled shoes, and deck areas for storing or releasing flammable or combustible materials. And that it should never smoke or handle fire in the vicinity and even near vents from the location.

However, in spite of such careful care and restriction regulations, if a large fire occurs due to small carelessness, it can cause enormous damage to the ship or human life. For example, a deck foam fire extinguishing system that injects foam fire extinguishing agents onto the deck in the event of a ship's deck fire and high expansion of foam fire extinguishing agent on the ceiling of each room when a fire occurs in the engine room or pump room. High expansion foam fire extinguishing system.

The foam fire extinguishing agent used in such a system is generally used for extinguishing Class B fires caused by a flammable substance such as crude oil or oil, and is mixed with sea water (or fresh water), and then the foam fire extinguishing agent, which is a mixed solution, is used. It is used to generate foam in the form of foam, and it is usually stored in a foam storage tank installed inside the hull, and when a fire breaks out, it is sprayed to the place of fire through a foam radiator or sprayer at the same time as the valve is opened.

1 is a configuration diagram of a conventional deck foam fire extinguishing device, Figure 2 is a configuration diagram of a conventional high expansion foam fire extinguishing device.

First, as shown in FIG. 1, the conventional deck foam fire extinguishing device includes a foam tank 11 in which a deck foam extinguishing agent is stored, a pump P11 for removing the deck foam extinguishing agent from the foam tank 11, and a pump for raising seawater ( P13), the mixer (13) is mixed with the seawater and deck foam extinguishing agent delivered from the pumps (P11) (P13), the foam spinning machine (17) is sprayed with the mixed extinguishing agent, pipes for connecting the respective components (19) Valves (V11) (V13) (V15) (V17) (V19) for controlling the flow of fluid flowing in the pipe (19) and the valves (V11) (V13) (V15) (V17) in case of fire. By controlling V19 and the pumps P11 and P13, the mixed fire extinguishing agent is sprayed into a fire place.

Therefore, in the conventional deck foam fire extinguishing device 10, when a fire occurs on the deck of the ship, the control unit 15 pumps (P11) (P13) and valves (V11) (V13) (V15) (V17) (V19) After the seawater and deck foam extinguishing agent is mixed in the mixer 13, the mixed extinguishing agent is sprayed to the fire place through the foam sprayer (17).
