Background
Existing wet mist fire suppression systems typically maintain water supply and water supply pressure for the overall system. When the wet type water mist spray head is in an intact state, the water mist cannot be released, and the whole fire extinguishing system is in a static state. As the temperature of the fire zone increases, the zone temperature reaches the glass packet melting temperature on the wet mist spray head, which will cause the glass packet to break. At this time, the wet water mist spray head reaches a release state, fire water in the pipeline is converted into water mist through the spray head and released to a fire area, and the aim of extinguishing fire is achieved.
The water mist release is completely dependent on the water mist spray head to detect fire and automatically release, when the glass bag is broken due to non-fire reasons, the water mist can be automatically released, and if a large number of electrical equipment or valuables are stored in the protection area at this time, serious loss can be caused by the false release of the water mist. The water mist release state of the water mist spray head can not be remotely monitored, and whether the water mist spray head works normally or not can not be remotely confirmed in a control room, and the water mist spray head must be confirmed in situ.
Therefore, how to provide a wet water mist spray nozzle fire extinguishing system, avoid the false release problem caused by non-fire causes, remotely monitor the water mist release state of the protection area, judge whether the water mist system works normally, and become a technical problem to be solved urgently.
