Vehicle mounted superfine spray fire extinguishing device

Abstract

The present invention discloses a vehicle-bone superfine water fog fire extinguishing device which is characterized by using a fire engine as a carrier and being provided with a water-air double-pipeline transmission system; the air pipeline comprises an air compressor and a pressure air pipeline which transmits high pressure air; the water pipeline comprises a pump and a pressure water pipeline which is communicated with a pump outlet and transmits high pressure water; the pressure air pipeline is joined up with the pressure water pipeline in a spray device; the high pressure water is cut by the high pressure air in the spray device and then is sprayed out as superfine water fog by a spray cylinder; and the fire extinguishing effect is far higher than fog water or water mist. The internal shape of the spray cylinder from an inlet to an outlet is the shape from convergent to spread and is accorded with the aeronautical dynamics and the fluid mechanics theory better, and the spray cylinder can maximize the ray range of the sprayed superfine water fog, so as to meet the requirement of remote fire extinguishing.

Description

Technical field: [0001] The invention relates to a vehicle-mounted fire extinguishing device, in particular to a vehicle-mounted ultrafine water mist fire extinguishing device. Background technique: [0002] Existing fire extinguishing fire trucks generally use water, foam liquid, dry powder and other fire extinguishing agents to be delivered to the spray gun or cannon through a single pipeline, and the sprayed fire extinguishing agent becomes a natural physical state, that is: water becomes water column or mist water, and the foam liquid passes through the spray gun or cannon. The air contact becomes a naturally formed ordinary foam, and the dry powder is directly sprayed to the fire scene, so a large amount of fire extinguishing agent is directly scattered on the ground without participating in fire extinguishing. Seriously, a large amount of fire extinguishing agent is not involved in fire fighting and wasted. Therefore, if the fire extinguishing agent is sprayed onto th...

Problems solved by technology

However, there is a technical difficulty in ultra-fine water mist fire extinguishing, which is how to spray ultra-fine water mist to the fire scene from a long distance. Due to the small diameter of ultra-fine water mist water particles, their own spray resistance in the air is large, which cannot meet the long-distance requirements. fire extinguishing requirements, this technical problem has not been successfully resolved
