Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is clearly and completely described.
Embodiment 1
As Figure 1-3, a kind of water-gas combined powder by atomization device, including nebulizer body 1, set on the nebulizer body
There are molten steel leak 4, air inlet 2, air slot 3, gas outlet, water inlet 6, guiding gutter 7 and 6 water atomizing nozzles 11；Molten steel leak
Resistant to elevated temperatures protective case 5 is provided between nebulizer body；The air slot and guiding gutter are annular groove.The air slot with
Air inlet is connected, and the gas outlet is connected with air slot；The guiding gutter is connected with water inlet, the water atomizing nozzle
It is connected with guiding gutter.The gas outlet is the ring-crack ventilation air stream outlet 10 gradually collapsed, and 6 water atomizing nozzles annular is
The injection line focus of cloth, the gas outlet and water atomizing nozzle is located on the center line of molten steel leak, and the spray line of gas outlet
Focus is higher than the injection line focus of water atomization outlet.
In the present embodiment, the air inlet inputs gases at high pressure, and high pressure high energy air-flow 8 is ejected in the gas outlet, described
Water inlet inputs water under high pressure, and high pressure high energy current 9 are ejected in the water atomization outlet.
This noodles making machine is mounted in the most crucial main part for water atomization pulverization on water atomization tower body, molten steel from
After molten steel leak is vertically fallen, high pressure high energy air-flow primary fragmentation is first passed through, then by high pressure high energy current second-time breakage, it is real
