Abstract

The present invention relates to a supersonic air-flow fire-extinguishing tank. It is characterized by that a supersonic air-flow fire-extinguishing apparatus is mounted on the tank chassis. Said supersonic air-flow fire-extinguishing apparatus can produce high-pressure high-energy air, said high-pressure high-energy air can be passed through a De Laval nozzle so as to produce a supersonic air-flow and make the pressure energy be converted into a kinetic energy, and said kinetic energy can be used for spraying extinguishant so as to attain the goal of extinguishing fire.

Description

technical field [0001] The invention belongs to the technical field of fire protection and relates to a supersonic airflow fire extinguishing tank. Background technique [0002] As a special fire-fighting technical equipment, the fire-fighting tank has the advantages of strong protection ability and good off-road performance. It is suitable for fighting special fires such as forest fires, gas explosions, and oil field blowouts. [0003] At present, commonly used fire-fighting tanks are: turbojet fire-fighting tanks, water-pump fire-fighting tanks. The former is to use the airflow from the tail nozzle of the turbojet engine to spray water-based fire extinguishing agent or foam fire extinguishing agent on the flame area to form aerosol, reduce the oxygen concentration and temperature around the flame area, suffocate and block radiant heat to achieve the purpose of fire extinguishing; the latter The water-based fire extinguishing agent is directly sprayed on the flame zone thr...
