Description

Technical Field

[0001] This invention relates to the field of foam fire extinguishing technology, and in particular to a high-efficiency fire suppression compressed inert gas foam fire extinguishing system. Background Technology

[0002] In the field of foam fire suppression technology, traditional foam fire suppression systems face numerous unresolved problems. Currently, most foam fire suppression systems rely on air compressors for air supply, a method with significant drawbacks. Air compressors require a large amount of electricity to operate, resulting in high operating costs. Furthermore, the flow rate and pressure stability of the air supplied by air compressors are poor, making it difficult to flexibly adjust according to the actual needs of the fire scene. In the event of a large fire, this means that the required amount of gas cannot be provided in a timely manner, delaying fire suppression efforts.

[0003] In terms of fire extinguishing effectiveness, the gas used in conventional foam fire extinguishing systems does not have special fire extinguishing advantages. In fact, air has a combustion-supporting effect. Therefore, due to the lack of inert gas, fire extinguishing relies solely on foam and water. When facing some special fires, such as oil fires or electrical fires, the fire extinguishing efficiency is low, and it is difficult to quickly and effectively suppress the spread of fire, which can easily cause greater losses.

[0004] To address the above issues, we propose a high-efficiency fire suppression compressed inert gas foam fire extinguishing system. Summary of the Invention

The nitrogen cylinder group delivers high-pressure nitrogen through the nitrogen delivery network. The foam liquid tank outputs foam liquid through the foam liquid delivery network. The water delivery network outputs water through the water delivery network. The foam liquid output from the foam liquid delivery network and the water output from the water delivery network are mixed and then mixed again with the high-pressure nitrogen delivered from the nitrogen delivery network and discharged through a mixed output pipe.

[0012] Preferably, a first flow meter and a fourth pressure regulating valve are installed sequentially on the pipe of the mixing output pipe.

[0013] Preferably, the nitrogen delivery pipeline network includes a first nitrogen pipeline and a second nitrogen pipeline. The nitrogen cylinder group is connected to the first nitrogen pipeline via a high-pressure hose. A fifth pressure regulating valve is installed on the first nitrogen pipeline. The first nitrogen pipeline is connected to the second nitrogen pipeline. The second nitrogen pipeline is connected to the mixing output pipe. A sixth pressure regulating valve, a first safety valve, a second flow meter, a second safety valve, and a ball valve are installed sequentially on the second nitrogen pipeline.

[0014] Compared with the prior art, the beneficial effects of the present invention are: In this invention, a compressed air foam fire extinguishing system is composed of a nitrogen cylinder group, a foam liquid tank, and water. At the output end of the nitrogen cylinder group, a fifth pressure regulating valve is installed on the first nitrogen pipeline, and a sixth pressure regulating valve, a first safety valve, a second flow meter, a second safety valve, and a ball valve are sequentially installed on the second nitrogen pipeline.
