Embodiment 1

[0025] In this embodiment, the chassis of the foam fire truck can be Mercedes-Benz Actros4163 8×4BB, the engine can be Mercedes-Benz OM501LA, the power take-off can be the full-power power take-off of NMV200 engine, and the rotation direction is counterclockwise (consistent with the rotation direction of the engine). The output and position are in the middle of the top, suitable for long-term use. See figure 1 , A water tank 1 is installed on the foam fire truck, and the water tank 1 supplies water to the water pump 3 through the water pipeline, and the water pump 3 also replenishes water to the water tank 1 through the water pipeline to ensure sufficient water. Between the water tank 1 and the water pump 3, butterfly valves 2 are arranged on the above-mentioned two water pipelines to control water inflow and outflow. The water pump 3 will deliver the water flow to the fire monitor 18 through the water pipeline, and this pipeline is also provided with two water outlet channel...

Embodiment 2

[0028] This embodiment is basically the same as Embodiment 1, and the difference is that: the nitrogen vehicle loaded with the compressed nitrogen system, that is, loaded with the nitrogen generating device 15, the air filter 16 and part of the gas pipeline, is composed of a tractor and a trailer, wherein The tractor can choose Mercedes-Benz Actros 1841LS 4x2 standard elite version, and the engine model is Mercedes-Benz OM501LA V-type 6-cylinder diesel turbocharged electronic injection engine with a power of 408 horsepower / 300 kilowatts. The flexible movement of this self-powered nitrogen vehicle can improve the road passability of the entire fire extinguishing system. In addition, this self-powered nitrogen truck and foam fire truck can drive to the fire scene separately, which can efficiently call for firefighting resources.

Abstract

The invention discloses a compressed nitrogen and foam fire-extinguishing system. The compressed nitrogen and foam fire-extinguishing system comprises a fire-extinguishing foam tanker and a nitrogen tanker, wherein the fire-extinguishing foam tanker is basically equal to a fire-extinguishing foam tanker in the prior art, the nitrogen tanker is provided with a compressed nitrogen system, the nitrogen system comprises a nitrogen generating device and a nitrogen delivery pipeline, and the nitrogen outlet end of the nitrogen generating device is connected with a water-foam mixing pipeline on the fire-extinguishing foam tanker to form a compressed nitrogen and foam liquid pipeline. The compressed nitrogen and foam fire-extinguishing system has the technical advantages that oxygen supported combustion in the air is completely eradicated, a foam insulation effect is improved, and the fire disaster suppressing capability is strengthened. The nitrogen generating device serves as an independent unit to constantly supply nitrogen, accordingly the operating capability of the whole fire-extinguishing system is improved, and the fire-extinguishing system is especially suitable for large fire disaster handling.

Description

technical field [0001] The invention relates to the technical field of land fire extinguishing vehicles, in particular to a compressed nitrogen foam fire extinguishing system. Background technique [0002] At present, when large-scale oil and petrochemical fires occur, compressed air foam is generally used to extinguish the fire. Its principle is to mix and foam air, water and foam under specific and proportional conditions to produce specific foam for fire extinguishing. Compared with direct water extinguishing, foam can improve the original physical properties of pure water, and has the functions of reducing the surface tension of water and increasing the coverage area of ​​water. Therefore, using foam to extinguish fire can quickly and effectively prevent the combustion chain reaction and greatly improve the fire extinguishing efficiency. . However, the air in the compressed air foam will bring fresh oxygen to the combustion, which has an adverse effect on rapid fire ex...
