Description

A kind of large-scale compression air foam system
Technical field
The utility model is related to a kind of fire-fighting system, particularly a kind of large-scale compression air foam system.
Background technology
CAFS (English name Compressed Air Foam System, referred to as CAFS systems, below Using referred to as), the Germany of the 1930s is come across earliest, reaches the practical stage in the U.S. the 1980s, is started Equip fire brigade.The mixing of common froth fire extinguishing system, foam mixing liquid and air simultaneously forms foam, usually in foam Sucking air is completed when rifle, big gun spray foam mixing liquid, belongs to suction type.The characteristics of CAFS systems is:High pressure gas is direct Foam mixing liquid is pressed into, belongs to positive-pressure type.For the foam of regular-type foam system injection, the foams mix of injection is more filled Point, foaming is more preferable, and the important indicators such as coefficient of foaming, drainage time of foam are much better than regular-type foam.
Common fire-fighting vehicle-mounted CAFS is all by water pump, foaming system, air compressor system, mixed pipe line System, injector (such as fire monitor, Fire branch), electric-control system composition.When work, water pump pressurizes water;Foaming system will Foam is mixed into water;Compressed air is directly injected into mixed pipe line by air compressor system again, is stirred by force with the mixed liquor of water/foam Mixing, foaming, form compressed-air foam;Finally, it is ejected from injector (such as fire monitor, Fire branch).Everything is moved Make, be all to be inputted to instruct by fireman, completed by electric-control system operation.
Vehicle-mounted CAFS since each device is installed in fire fighting truck, is limited by the vehicle of fire fighting truck Interior space, the capacity for the air compressor machine installed is also smaller, and total emitted dose of compressed-air foam is limited always, is mostly used for It puts out a fire to save life and property middle-size and small-size A classes fire and small-sized B classes fire.For the exigent large size B class fire of strength of attack, disposable requirement spray The fire-fighting dose penetrated is very big, and domestic common fighting fires with compressed-air foam vehicle is difficult to meet requirement at present.
Utility model content
The goal of the invention of the utility model is:For the current common compressed-air foam in the country of the existing technology Fire fighting truck is difficult to the deficiency for meeting the requirement of large-scale B classes fire, provides a kind of large-scale compression air foam system.
