Fire smoke removing system with coupling effect of sound waves and spray and smoke removing method

Abstract

The invention discloses a fire smoke removing system with a coupling effect of sound waves and spray and a smoke removing method using the system and belongs to the technical field of firefighting andsafety. The system comprises a loudspeaker sound source fixedly arranged on the side wall of a building passage or room and a water atomization nozzle fixedly arranged at the top of the building passage or room. In a fire disaster, when fire smoke spreads all over the building room or passage, the loudspeaker sound source and the water atomization nozzle are started simultaneously. The loudspeaker sound source is used for producing a high-intensity sound field, fine particulate matter in the fire smoke can collide and agglomerate by use of the sound wave agglomeration mechanism, the number ofthe particulate matter can be substantially reduced, and the visibility can be improved. Droplets contained in water spray can further increase the agglomeration effect and avoid breakage of agglomerated particulate matter. The fire scene visibility can be substantially improved within several seconds under the coupling action of sound waves and water spray, and escape of people in the fire disaster is guaranteed.

Description

technical field [0001] The invention relates to the technical field of fire protection and safety, in particular to a fire smoke removal system using the coupled action of sound waves and sprays and a method for eliminating smoke using the system. Background technique [0002] Fire has brought great harm to human beings, causing a large number of casualties and property losses every year. Smoke is the biggest fatal factor in fires. According to research, the number of people killed by smoke accounts for about 80% of the total number of fire deaths. [0003] The greatest harm of fire smoke is reflected in its shading properties, which lead to a sharp reduction in the visibility of building passages and indoor spaces in the early stage of a fire, and the trapped people cannot quickly evacuate the fire scene, increasing the possibility of poisoning and being burned to death. Countries generally believe that when the visibility distance is reduced to 3 meters, it becomes very d...

Problems solved by technology

[0004] Therefore, smoke control is an important measure to reduce casualties in building fires. Common methods include smoke shielding, mechanical smoke exhaust, natural smoke exhaust, pressurized air supply to prevent smoke, spraying fine water mist, etc., but the actual effect is not obvious. Difficult to function in an actual fire
