Embodiment

[0022] Embodiment: As shown in Fig. 1, the vehicle-mounted ultra-fine water mist fire extinguishing device of the present embodiment uses a fire truck as a carrier and adopts a "water-gas" dual-pipeline delivery system, and the gas pipeline includes an air compressor 1 and a delivery high-pressure The pressure gas pipeline 2 of the gas, one end of the pressure gas pipeline 2 is connected to the outlet of the air compressor 1, and the other end is connected to the injection device 3, and the pressure gas pipeline 2 is also provided with a flow meter 4 and a check valve 5, which can control the flow rate in the pipeline. Control the flow, direction and velocity of the compressed gas. Parallel with the gas pipeline is the water pipeline, which includes a water pump 6 and a pressure water pipeline 7 communicating with the outlet of the water pump to deliver high-pressure water. A flow meter and a check valve are also arranged on the pressure water pipeline 7 to control the high pre...

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...
