Publication number: 20240226624Abstract: The present disclosure provides an air mixer for a compressed air foam (CAF) fire-extinguishing system. A foam concentrate and compressed air are respectively transported by a liquid inlet pipe and an air inlet pipe. When the compressed air and the foam concentrate enter a straight pipe through a first tapered pipe, they reach an outlet end of the first tapered pipe through a path narrowing due to different cross-section diameters at two ends of the first tapered pipe, and there is a compression process. Under an action of a high-pressure airflow, the foam concentrate is fully mixed. The mixed foam concentrate reaches a porous plate of the straight pipe and can be mixed secondarily. When the foam concentrate is discharged by a second tapered pipe, a flow path widens and there is a release process.Type: ApplicationFiled: August 1, 2022Publication date: July 11, 2024Inventors: Jiaqing Zhang, Yong Huang, Yifu Zhou, Jinzhong Li, Xiaodong Zhang, Dengfeng Cheng, Sha Luo, Yi Guo, Fengju Shang, Yubiao Huang, Rui Liu
