The traditional high-pressure water fire-fighting fire-extinguishing apparatus in China has the advantages that the high-pressure water flow mobility is strong, the fire extinguishing range is far, the pressure is large, the fire extinguishing principle is the same, the purpose is to enable a combustion object to be oxygen-isolated and flame-retardant, the combustion object is instantly extinguished and the fire extinguishing area is prevented from being enlarged, the traditional high-pressure water fire-extinguishing apparatus has the advantages that the high-pressure water flow mobility is strong, the fire extinguishing range is long, the pressure is large, the defects are that the combustion object is easily blown away and blown away, the fire extinguishing area is enlarged, the fire extinguishing is not facilitated, the combustion object is not oxygen-isolated and flame-retardant, the solid fire extinguishing agent has the advantages of good oxygen-isolation and flame-retardant effects, the defects are poor in fluidity and diffusivity, the dropping distance is low, the water flow distributor enables one person to flow into the water distributor along the water distributor, the stress entering the water distributor is reduced, the water distributor enables the water distributor to be concentrated, the water distributor to enable the fire-extinguishing apparatus to be uniformly distributed on the fire-extinguishing apparatus, the fire-extinguishing apparatus to be uniformly distributed on the circumference surface of the fire-extinguishing apparatus, and the high-pressure water-spraying area is not favorable, if the high-pressure water-spraying area is not favorable, the high-pressure water-high-pressure water-flow rate is required by the high-pressure-high-pressure water-pressure-high pressure-pressure water-high pressure water-pressure-water-high-water-pressure-.
The foam fire extinguisher prepared by high-pressure water overcomes the defects of liquid and solid fire extinguishers, the liquid mainly adopts high-pressure water for fire extinguishment, and the two advantages are combined together, namely the foam fire extinguisher prepared by high-pressure water has strong liquidity, long range, high pressure, oxygen isolation, high flame retardance and good effect.
If a high-pressure water fire extinguisher is adopted for inflammable oil combustion objects, the high-pressure water pressure is high, the fire passing area is easily and rapidly enlarged, and the fire extinguishment is not facilitated.
The reference CN206350885U is a water film-forming foam fire extinguisher, which is a high-expansion foam { paragraph 0016 } in the specification, wherein a liquid storage tank stores water foam fire extinguishing agent, a high-pressure pump is started to pressurize and a liquid discharge valve, the water foam fire extinguishing agent in the liquid storage tank is pumped into a pressure equalizing tank by the high-pressure pump through a liquid discharge pipe, the high-pressure foam fire extinguishing agent enters a first mixing tank under the distribution of the pressure equalizing tank and is impacted and mixed with high-pressure water sprayed out of a spray seam, the reference is that the water foam agent and the high-pressure water (called fire water in the reference) are impacted with each other, enough time is provided for mixing, the water foam agent and the fire water are uniformly mixed, the foam liquid is generated by foaming the liquid, the reference is that the foam agent and the fire water are impacted with each other to form bubbles and are fully mixed in two stages (the mixing tank 4 and the mixing tank 8 are fully mixed twice), the foam size is uncontrollable, and the foam is a high expansion method, higher multiple, larger foam, thinner wall, more brittle, poor flow, slow spray rate and close proximity
Like high-pressure water injected into the laundry detergent to instantly generate foam, the foam has large size, thin wall, poor fluidity, close range, different foam size, large foam is several times or even dozens of times of small foam, poor consistency, during the spraying process, the water velocity and the foam velocity are different, i.e. the water velocity is far in range, and the foam is near in range, the foam is broken instantaneously, as described in paragraphs 0014 and 0015 of the specification, the application document directly utilizes high-pressure water to generate, the water obtains larger kinetic energy, the water collides with the screen with the same mesh number, the energy in the water molecules is released, the volume is increased, foam balls are formed, and after the screen with the determined mesh number, the foam size is controllable, the foam is round small balls defined as foam balls, the consistency of the foam balls is high, the water flow speed and the foam speed in the injection are the same, the foam is not easy to break, and the foam ball are different from each other in principle and structure.
The present invention has the following advantages.
1. The foam fire extinguisher prepared by high-pressure water has strong mobility, long range, large pressure, oxygen isolation, fast flame retardance and good fire extinguishing effect.
2. The mesh size is related to the size of the generated foam, and different meshes of the screen are selected to generate the foam with the size suitable for instantly extinguishing the comburent.
The water flow distributor enables high-pressure water to flow into the water distributor along the outer circular surface of the water flow distributor, so that the concentrated stress of the high-pressure water entering the water distributor is reduced, and the recoil and the pulsation of the traditional high-pressure water fire-fighting fire-extinguishing apparatus are eliminated.
