Embodiment 1

[0075] For the foam generation module in the CAFS in this embodiment, the foam outlet and the foam mixture inlet of the foam generator 1 are respectively located at both ends of the cylindrical structure. The relationship between the diameter D2 of the foam mixture inlet and the diameter D3 of the liquid nitrogen inlet is: D2 / D3=8; the relationship between the diameter D1 of the cylindrical structure and the diameter D2 of the foam mixture inlet is: D1 / D2= 1.4; the relationship between the diameter D1 of the cylindrical structure and the diameter D4 of the foam outlet is: D1 / D4=1.2; the angle between the direction of the liquid nitrogen inlet and the direction of the foam mixture inlet is 30°. A spoiler is arranged in the foam generating chamber, and the spoiler is formed as image 3 As shown in the conical structure, the conical apex of the conical structure faces the inlet of the foam mixture, the cross section of the spoiler is a circular structure, and the diameter D7 of t...

Embodiment 2

[0090] The CAFS in this embodiment is basically the same as the CAFS in the above-mentioned embodiment one, and the difference is that the relationship between the diameter D2 of the foam mixture inlet of the foam generator in this embodiment and the diameter D3 of the liquid nitrogen inlet is: D2 / D3=10; the relationship between the diameter D1 of the cylindrical structure and the diameter D2 of the foam mixture inlet is: D1 / D2=1.7. The test results of using the CAFS to extinguish the fire show that the fire extinguishing time is 22 minutes, the actual foaming ratio is 7, and the foam performance is stable.

Abstract

The invention discloses a foam generating module and foam fire-fighting equipment. The foam generating module comprises a foam generator, the foam generator is provided with a foam generating cavity with a foam mixing solution inlet, a liquefied medium inlet and a foam outlet, the foam mixing solution inlet is connected with a mixer conveying a foam mixing solution to the foam generating cavity, the liquefied medium inlet is connected with a liquefied medium storage device conveying a liquefied medium to the foam generating cavity, the liquefied medium and the foam mixing solution are mixed, gasified and foamed in the foam generating cavity, fire-fighting foam is conveyed out from the foam outlet, wherein the mixer is provided with a mixing cavity with a stock solution inlet and a water inlet, the stock solution inlet is connected with a foam stock solution storage device conveying a foam stock solution to the mixing cavity, and the foam stock solution conveyed from the stock solutioninlet and water conveyed from the water inlet are mixed in the mixing cavity to generate the foam mixing solution. The provided foam generating module and the fire-fighting equipment produce a large flow of high-power foam, the volume is small, and the space is saved.

Description

technical field [0001] The invention relates to fire-fighting and fire-extinguishing technology, in particular to a foam generating module and foam fire-extinguishing equipment. Background technique [0002] Existing compressed gas foam fire extinguishing mainly adopts the mode of mixing gas and foam mixture to generate foam for fire extinguishing. The specific compressed gas foam fire extinguishing methods mainly include atmospheric pressure compressed gas foam fire extinguishing and gas storage foam fire extinguishing methods. [0003] Among them, atmospheric compressed gas foam fire extinguishing usually uses compressors or compressed gas cylinders for gas supply, and the air supply volume of compressors and compressed gas cylinders is limited, which cannot meet the requirements of large flow and high pressure gas supply. For large flow and high pressure gas supply, multiple compressors or compressed gas cylinders need to be installed (for example, a foam fire truck with...
