Abstract

The invention discloses a double-aerosol-extinguishant spraying device which comprises a high-shooting-speed fan or an aero-gas turbine, an aerosol extinguishant spraying tube, a water supply ring, a foamite supply ring, a superfine dry powder extinguishing agent spraying gun, a superfine water mist spraying nozzle, a foamite spraying nozzle, a first solenoid valve, a second solenoid valve and a third solenoid valve. The double-aerosol-extinguishant spraying device achieves mass flow and high-shooting-speed spraying. Double-aerosol-extinguishant jet flow sprayed by the double-aerosol-extinguishant spraying device is sprayed into an internal space of a building on fire, aerosol extinguishants are rapidly dispersed to generate a 'totally flooding' state and enter the interior of flames under the action of entrainment airflow of the flames, and consequently a fire in the building can be rapidly put out, and the flames are prevented from reburning.

Description

Technical field

[0001] The invention belongs to the technical field of fire fighting, and particularly relates to a dual aerosol fire extinguishing agent spraying device. Background technique

[0002] From the beginning of the last century to the end of the 1920s, water jet fire trucks, foam fire trucks, and dry powder fire trucks appeared in the world. These highly maneuverable fire trucks played a role in fighting violent fires such as urban fires and petrochemical plant fires. It plays an important role and is the main fire fighting equipment in the current fire fighting. But the actual fire fighting also revealed its technical flaws. These defects are: the water jet fire truck forms a line of water jets from the outlet of the jet gun (cannon) to the fire source, and extinguishes the fire by impacting and cooling the fire source by the water jet. This "point-to-point" method of spraying fire extinguishing agent is " One-dimensional spray mode of fire extinguishing agent", wh...
