Description

Technical Field

[0001] The utility model relates to the field of fixed fire extinguishing equipment, in particular to a perfluorohexanone fire extinguishing system capable of multiple spraying. Background Art

[0002] At present, the common fixed fire extinguishing systems in China are generally continuous spraying or single pulse spraying types. When there is a re-ignition at the protected site, they cannot meet the continuous fire control needs within a certain period of time.

[0003] The common automatic sprinkler fire extinguishing system is a continuous spraying type fire extinguishing system. Although this type of fire extinguishing system has good fire extinguishing effect and has a certain period of continuous spraying performance, it uses water as the fire extinguishing medium. After the fire is extinguished, it will cause a lot of water damage to the protected objects. It is conductive and cannot be used in some special places such as live equipment, precision equipment, valuable equipment and cultural relics and archives; common gas fire extinguishing systems such as HFC-227ea fire extinguishing systems, relevant design specifications require that the system spraying time shall not be greater than 10s. When the system receives a trigger signal, the fire extinguishing agent needs to be quickly sprayed within ≤10s. Once sprayed, it cannot be stopped. Although the application range of this single pulse spraying type fire extinguishing system is wider than that of the water system, it still cannot meet the fire extinguishing and fire control needs of special places with re-ignition.

[0004] To this end, the present application designs a perfluorohexanone fire extinguishing system capable of multiple spraying to solve the above problems. Summary of the Invention
