[0002] Indoor fire protection system refers to a facility system installed indoors to extinguish fires that occur in the building. For most factory buildings, a water spray structure is generally set up for fire extinguishing. The existing water spray mechanism is generally composed of a large flow of fire water spray. During the fire extinguishing process, a large flow of fire water will cause water damage; therefore, some fire water heads now use spray to extinguish fires, but the spray method also has great limitations. Specifically, in the early stage of a large fire, the spray method cannot play a good fire extinguishing role, but in the middle and late stages, the spray method can play a better cooling and oxygen isolation role than the water spray method.
