Fire-fighting vehicle-mounted vortex jetting fire extinguisher

Abstract

An aero fire extinguisher on fire-fighting truck is characterized in that a turbojet engine is arranged on a fire-fighting truck; a fire extinguishing agent cartouche is installed at the rear part of the turbojet engine; a circular water channel is arranged around the mouth of the fire extinguishing agent cartouche; fire extinguishing agent spray nozzles are evenly spread along the circular waterchannel, which are inclined; the jet axis lines of the inclined fire extinguishing agent spray nozzles form a cone before the fire extinguishing agent cartouche. The invention uses tail gas from the engine as the power of spraying fire extinguishing agent, is mainly used in fire protection in airports, oil and gas fields and large petrochemical enterprises, and meanwhile has functions such as smoke elimination, temperature reduction and dustproof, etc., so that the rescuers can quickly enter the fire scene to rescue the people in trap.

Description

technical field [0001] The invention relates to a fire-fighting fire-extinguishing device, more specifically, a vehicle-mounted fire-fighting fire-extinguishing device that is especially suitable for large-scale fire-fighting in airports, oil and gas fields, and large-scale petrochemical enterprises. Background technique [0002] For firefighting in airports, oil and gas fields and large petrochemical enterprises, firefighting devices are required to have the functions of rapid fire extinguishing, smoke elimination, cooling and dust removal in a large area, so that personnel can enter the fire scene as soon as possible for rescue. But existing fire-fighting equipment all can't meet this requirement. [0003] The turbojet engine can produce high-velocity gas during work, and the power can reach thousands or even tens of thousands of kilowatts, which fully meets the injection power as a fire extinguishing agent. However, this technology has not been well applied in fire extin...

AI Technical Summary

Problems solved by technology

[0004] 1. Under unconstrained conditions, the water and air jets collide directly to exchange kinetic energy. This energy exchange method makes the particle size of the water mist larger, the diffusion angle of the jet is also larger, and the water mist jet sinks faster. It is only suitable for use Cooling, controlling and extinguishing fires in large areas

[0005] 2. Relying on external fire extinguishing agents to extinguish fires cannot extinguish fires at the first time and at the fastest speed, nor can different methods be used to extinguish fires according to different fires

[0006] 3. Using 28v power supply, it is composed of four aviation batteries connected in series and parallel to start the turbojet engine, but the aviation battery is not only heavy, but also requires daily maintenance such as charging and liquid replacement, which brings inconvenience to use
