Abstract
The invention relates to a porous spray nozzle of a superfine dry powder and eruptively-generated aerosol fire extinguishing system. The porous spray nozzle comprises a pressure storage body chamber, Laval nozzles and a conveying pipeline, wherein the Laval nozzles are arranged on the pressure storage body chamber; the conveying pipeline is connected with one end of the pressure storage body chamber. By the arrangement of the Laval nozzles on the extensional cylindrical or cone frustum-shaped side surface and one end surface of the pressure storage body chamber and the adoption of the advanced Laval nozzle technology, the porous spray nozzle ensures that the release speed of a superfine dry powder fire extinguishing agent at the nozzle is sharply increased, so that the dispersion performance and extinguishing efficiency of the superfine dry powder fire extinguishing agent for total flooding extinguishing are improved, the design concept of a single-hole spray nozzle or common porous spray nozzle adopted by the existing superfine dry powder fire extinguishing system is broken through, and the spray nozzle and the fire extinguishing agent achieve a synergistic effect. The porous spray nozzle has a simple structure, is convenient to operate, and improves the spraying performance and fire extinguishing performance of the superfine dry powder fire extinguishing system.
