PROBLEM TO BE SOLVED: To provide a simple foaming device for foam extinguishment facility which can improve foam performance.SOLUTION: In a foaming device for foam extinguishment facility, a foam extinguishment agent mixture, which mixes a foam extinguishment agent and water, is jetted from an orifice 1, thereby air is suctioned from an air intake port 2 into an extinguishment foam solution radiation tube 4 by means of negative pressure in the extinguishment foam solution radiation tube 4, extinguishment foam solution, which agitates and mixes the foam extinguishment agent mixture and air inside, is radiated from a radiation port 3 into a foam chamber 5 to collide against a top plate 7 of the foam chamber 5 and foam, and extinguishment foam is discharged from a foam injection port 10 opened on a cylindrical wall 8 of the foam chamber 5. A weir plate 11 is arranged before the foam injection port 10, the weir plate being positioned between the radiation port 3 of the extinguishment foam solution radiation tube 4 and the foam injection port 10 opened on the cylindrical wall 8 of the foam chamber 5, blocks a foam flow toward the foam injection port 10, and bypassed by and flow the foam flow to the foam injection port 10.SELECTED DRAWING: Figure 1 |
