Abstract
The utility model discloses a mixed type main fire-extinguishing system of a roll-on roll-off ship. The mixed type main fire-extinguishing system comprises vehicle-carrying areas A and B below a main deck, and a CO2 main fire extinguisher in an engine room area, wherein the other four vehicle cabins on the main deck are water mist spraying main fire extinguishers. By comparison with the prior art, the number of CO2 bottles formed in the mixed type main fire-extinguishing system is small, the space is saved, the safety coefficients of people and equipment are greatly improved, and the loading capacity of the vehicle cabins is improved.
Description
Technical field
The utility model relates to the mixing class master fire extinguishing system of roll-on-roll-off ship.
Background technology
For many years, our factory mainly adopts CO to machinery space and cargo area on container ship, multi-purpose cargo ship and big or middle handy-size bulk carrier
2Main fire extinguishing system is so be referred to as " single class " main fire extinguishing system.Its place, cabin only is that five zones (main frame, generator, boiler, centrifugal oil separator, incinerator) carried out local mist fire-fighting.Therefore according to SOLAS requirement, CO
2Fire extinguishing system can be at CO
2Between manual operation and fire station straighforward operation, remote control system and audible alarm interlocking, institute takes up space larger.
Above-mentioned " single class " fire extinguishing system mainly solves effective fire extinguishing that can reach in the airtight place, because CO
2Be applicable to put out category-B fire (solid matter that liquid maybe can melt, gasoline, kerosene), fuel gas C class fire etc.
The utility model content
The purpose of this utility model provides a kind of mixing class master fire extinguishing system of roll-on-roll-off ship, forms by contrast CO
2The quantity of bottle is few, conserve space, and safety coefficient artificial and equipment increases substantially, and has also improved the useful load of vehicle hold simultaneously.
The technical solution of the utility model is as follows:
The mixing class master fire extinguishing system of roll-on-roll-off ship includes that A, B under the main deck carries the car district and area of aircraft cabins is CO
2Main fire extinguisher, other four vehicle holds are water mist sprinkling master fire extinguisher on the main deck.
Described A, B carry the car district and area of aircraft cabins is CO
2Main fire extinguisher and water mist sprinkling master fire extinguisher, nozzle quantity mostly is 23 most, and nozzle flow is 5L/m
3.min.
Compared with prior art, the beneficial effects of the utility model are as follows:
1, single class master's fire extinguishing system CO
2Air release need to be in airtight space, and at this moment, personnel need withdraw immediately, and ventilation equipment cut out.And carry the car zone and carry out a mist fire-fighting opening wide, mix class master fire extinguishing system if adopt, neither need confined space, the personnel that also need not withdraw, and also are best to the protection of various kinds of equipment.Because sense cigarette and sense flame probe be interlocking each other, the misoperation of having stopped shower nozzle has improved security.Realized " harmony " of people and equipment, reached environmental protection.
2, single class master's fire-extinguishing apparatus cleans, maintenance drops into greatlyr, and particularly misoperation causes that personnel's danger is larger, looks according to condition of a fire sort operation and mix class master fire extinguishing system, reduces the maintenance loss.
3, single class master's fire extinguishing system is CO
2Main fire extinguishing is calculated according to maximum capacity according to standard, determines CO by modular formula
2The quantity of bottle, the capacity total amount of common cargo area is greater than the cabin, so CO
2The bottle quantity more, so the institute take up space larger.
And mix the class fire extinguishing system by the zone customization, and also can complement one another simultaneously, therefore determine: cabin (comprising A, B vehicle hold) is CO
2+ local water smoke, nozzle quantity mostly is 23 most usually, and nozzle flow is 5L/m3.min, satisfies 20 minutes fresh water requirement.The main deck vehicle hold is: low pressure water smoke+portable CO
2Fire extinguishing.Form by contrast CO
2The quantity of bottle is few, conserve space, and safety coefficient artificial and equipment increases substantially, and has also improved the useful load of vehicle hold simultaneously.
4, this ship mixes the particularly application of the main body of low-pressure water mist system of employing of class master fire extinguishing system, and from the water smoke fresh-water tank water intaking of special use, this spraying system also can be connected on the ship's fire fighting house steward, and not only simply but also reliable, its system flow chart was as follows:
Wherein:
Two water smoke pump discharges are respectively 180m3/h, lift: 97m
Some fire-fightings zone is divided according to design arrangement in four layers of deck
C layer deck high velocity projector quantity is 92 (code name is ZSTWB43/120)
Capacity of sprinkler is 80L/min
The radius of protection of each shower nozzle is 2700, and shower nozzle is apart from altitude above deck 2950
It is 135+148+148=431 that shower nozzle quantity is adopted on D, E, three layers of deck of F
Capacity of sprinkler is 50L/min, and radius of protection is 2500
Shower nozzle is apart from altitude above deck 2050(code name: ZSTWB26.5/120).
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, the mixing class master fire extinguishing system of roll-on-roll-off ship includes that A, B under the main deck 1 carries the car district and area of aircraft cabins is CO
2Main fire extinguisher, other four vehicle holds are water mist sprinkling master fire extinguisher on the main deck 1, A, B carry the car district and area of aircraft cabins is CO
2Main fire extinguisher and water mist sprinkling master fire extinguisher 2, nozzle quantity mostly is 23 most, and nozzle flow is 5L/m
3.min.
