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 can

Example Embodiment

[0037] Referring to Figure 1, a fire truck 1 is used as a carrier.

[0038] Referring to Fig. 1, Fig. 2 and Fig. 3, a turbojet engine 2 is installed on the fire truck 1, a fire extinguishing agent injection cylinder 3 is installed at the rear of the turbojet engine 2, and an annular ring is arranged around the mouth of the fire extinguishing agent injection cylinder 3. In the water channel 4 , the fire extinguishing agent nozzles 5 are evenly distributed along the annular water channel 4 , and the fire extinguishing agent nozzles 5 are arranged obliquely.

[0039] The corresponding structural settings in the specific implementation also include:

[0040] Below the vortex jet cylinder 3 at the position of the annular water channel 4, a fire extinguishing agent inlet 9 is arranged that is communicated with the annular water channel 4; in order to ensure the atomization effect of the water mist, the fire water pump 8 is set as the fire extinguishing agent inlet 9 Provide a fire ...

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 water channel, 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...
