Title:
FIRE EXTINGUISHING FOAM GENERATION DEVICE AND FIRE EXTINGUISHING FOAM GENERATION DEVICE UNIT
Document Type and Number:
Japanese Patent JP2021019666
Kind Code:
A
Abstract:
To provide a compact and light weight fire extinguishing foam generation device capable of manufacturing fire extinguishing foam at low cost.SOLUTION: A fire extinguishing foam generation device includes: a mixing part 1 for generating fire extinguishing foam F by mixing water W, a fire extinguishing agent solution L, and compressed air A; a fire extinguishing agent solution supply part 2 for supplying the fire extinguishing agent solution L to the mixing part 1; and a compressed air supply part 3 for supplying the compressed air A to the mixing part 1. The mixing part 1 includes a water supply port 1a to which pressurized water is supplied from a pressurized water supply source, and a foam discharging part 1b for discharging the fire extinguishing foam generated in the mixing part 1. The fire extinguishing agent solution supply part 2 includes a fire extinguishing agent solution container 2a in which the fire extinguishing agent solution L is stored, a pneumatic driving pump 2b for sending the fire extinguishing agent solution L in the fire extinguishing agent solution container 2a to the mixing part 1 with required pressure, and an introduction pipe 2c for introducing the compressed air from the compressed air supply source to the pneumatic driving pump 2b. The compressed air supply part 3 includes an air introduction pipe 3a for introducing the compressed air from the compressed air supply source to the mixing part 1.SELECTED DRAWING: Figure 2
