Title:
AIR FOAM FIREFIGHTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/016143
Kind Code:
A1
Abstract:
An air foam firefighting system, consisting of a jetting system, a water supply system, an air supply system and a foam supply system. The jetting system is in communication with the water supply system, the air supply system and the foam supply system. The water supply system and the air supply system are self-powered supply systems, and the foam supply system is powered by the water supply system to supply a foam mixture via a Venturi negative pressure supply device. The jetting system is a cylindrical hollow structure independently arranged on a backpack-type or small vehicle mobile structural body, and comprises a firefighting spray pipe, a water, foam and air mixing device, and various medium inlets. The air foam firefighting system uses wind power as a jetting force of the firefighting system, may be used as an air firefighting device for forest firefighting, and may also be used for many other types of firefighting situations. The jetting system fully mixes a firefighting agent with water, further foaming and jetting is driven by the force wind, and the jetting distance is significantly extended. In conditions of relatively difficult fire scene traffic, the present invention fully achieves the goal of a light, portable, short-distance system which implements large-force firefighting.
