【 摘 要 】

In view of the high-pressure water mist application problems, a method of self-rotating spray extinguishing class B fires was put forward with the pre-mixed compressed air and low-pressure water.The self-rotating spray fire extinguishing system of pre-mixed compressed air and low-pressure water and a high-pressure water mist fire extinguishing testing system were established, and the spray performance and fire suppression performance were tested respectively. The results showed that the self-rotating spray had finer and more evenly droplets, bigger effective spray radius, lower system pressure, more reduction in water quality requirements, less clogging nozzle than the high-pressure water mist under the basically same water consumption. The effective fire extinguishing distance of self-rotating spray fire was 2.5m and the effective fire extinguishing radius was 1.5m, which was better and would be more applicable for engineering applications than high-pressure spray fire extinguisher.
