Estimating the term…
The application discloses a mixed-spray firefighting device, which includes a water nozzle and a powder nozzle. The water nozzle is disposed around an outside of the powder nozzle, and a powder spray port of the powder nozzle is provided behind a water spray port of the water nozzle. A fire-extinguishing agent powder sprayed from the powder nozzle and a water flow sprayed from the water nozzle are mixed in air outside the firefighting device. The fire-extinguishing agent powder is preferably sodium polyacrylate resin powder. The application solves the technical bottleneck of using the sodium polyacrylate resin powder as a fire-extinguishing agent in the prior art, so that the sodium polyacrylate resin powder can be sprayed into a fire field smoothly and continuously without blocking the powder spray port.
A mixed-spray firefighting device, comprising a water nozzle and a powder nozzle, wherein the water nozzle is disposed around an outside of the powder nozzle, and a powder spray port of the powder nozzle is disposed behind a water spray port of the water nozzle.
A mixed-spray method of powder fire-extinguishing agent and water, wherein a superabsorbent resin fire-extinguishing agent powder sprayed from a powder spray port of a powder nozzle is sprayed from the powder nozzle and is mixed with a water flow sprayed from a water spray port surrounding the powder nozzle in air outside a water nozzle, and the water nozzle is disposed around an outside of the powder nozzle.
