  • Publication number: 20240226624
    Abstract: 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.

  • Publication number: 20230153737
    Abstract: A method for evaluating the effectiveness of a transformer fire extinguishing system based on a natural language fuzzy analysis is provided, and a method and device for evaluating the fire extinguishing system are established. An expert fuzzy evaluation matrix is established by natural language fuzzifying and de-fuzzifying methods for the effectiveness of the fire extinguishing system. According to the relative influence of each index in the evaluation index system of the effectiveness of the fire extinguishing system, the weight comparison of each index is determined, and the index subjective weight is established based on the weight comparison of each index. A de-fuzzified matrix is obtained by de-fuzzifying an expert fuzzy evaluation matrix, and based on the de-fuzzified matrix, an objective weight is obtained by an entropy weight method. A comprehensive weight is obtained by combining the subjective and objective weights.
