Problems solved by technology

The operating pressure of this nozzle is from 3 bar (45pis) to 7 bar (100pis), because the relative momentum generated by this nozzle is low, so the scope of action is limited to the cooling and dilution of low volatility liquid fire on hand nozzle

Abstract

A diffusion impact type water-atomizing nozzle for extinguishing fire accident and cooling gas turbine, or used as moistener is composed of a main body with water inlet, small hole and conic water outlet arranged along central axis, and a diffuser under said main body and consisting of 3-6 U-shaped impact needles uniformly surrounding said water outlet to form an impact plane.

Description

technical field [0001] The invention relates to an atomizing device or a nozzle, in particular to a diffusion and impact type fine water mist nozzle. Background technique [0002] According to different classification standards, such as the way water mist is generated, the pressure generated by water mist, etc., there are many different classification methods for fine water mist nozzles. [0003] The methods of water mist generation usually include: diffusion impact, pressure jet, gas atomization and jet interaction. [0004] Diffuse impact type fine water mist nozzle is to collide the relatively stable water flow into the diffuser at a medium speed, and the diffuser will decompose the water flow into high-momentum water mist of various sizes. The water droplets are smaller than 600 microns. The working pressure range of impingement nozzles currently on the market is from about 7 bar (100pis) to 17.2 bar (250pis). For fire protection, the impingement nozzle can be a close...
