Fire extinguishing device for fire engineering and method of use thereof

Abstract

The application discloses a fire extinguishing device for fire engineering and a use method thereof, and particularly relates to the technical field of fire engineering. The device is provided with a heat conducting component, an air treatment device, an air suction fan and a driving device. When air moves along the spiral guide rail with the operation of the air suction fan, the air will fully contact with the copper net. The oxygen in the air will react with copper to generate copper oxide when passing through the hot copper net. The fire extinguishing device can consume a large amount of oxygen in the air through the heating mode of the copper net, so that the fire extinguishing device can effectively block the contact between air and combustible materials when discharging fire extinguishing materials through the fire extinguishing pipe. The oxygen contained in the air discharged by the fire extinguishing device is difficult to support the combustion of combustible materials. Since the fire extinguishing device only uses foam and oxygen-free gas for fire extinguishing, the harm to fire extinguishing personnel and fire extinguishing objects is avoided, the economic loss is reduced, and the safety during fire extinguishing is improved.
