Embodiment Construction
[0040] The fire-fighting water comes from the fire-fighting water pipeline, and enters the inflow section a through filters and other equipment. Pass through the bypass pipe 4 to bypass the gas injection section and reach the swirl mixing section c.
[0041] The main flow enters the gas injection section, and the atomizing gas (usually N 2 ) enters the atomizer body cavity 6 through the airway connected to the outer gas injection pipe connection hole 5, and then enters the main flow through the inner gas injection hole 7 for mixing, wherein there are 4 outer gas injection holes, which are evenly distributed on the circumference and located close to the swirl section; the inner gas injection holes There are 6, evenly distributed on the circumference, and the position is close to the incoming flow section.
[0042]The main flow flowing out of the gas injection section is fully mixed with the three bypass water flows in the swirl section c, where the main flow is also mixed with...
