Between gap play the role of the pressure stabilizing chamber for making air-flow pressure stabilizing.If this gap is excessive, air-flow can not form rotation, be not easy
Cooling water is broken up, atomizing effect is bad；If this gap is too small or even gapless, air-flow is extremely unstable, easily blocks.By
Test of many times, it has been found that when gap is 50-80 i.e. 0.5-0.8mm, the air-flow that nozzle sprays is more stable, while also can
Cooling water is preferably broken up, droplet particle is smaller, and atomizing effect is preferable.In above-mentioned numberical range, 0.6mm is that steam leads to ring 16
With the best clearance between outflow atomizer 8, the air-flow that nozzle sprays is most stable, while also can preferably break up cooling water,
Droplet particle is minimum, illustrates that atomizing effect is best.
(the lower section outer wall of atomizer 4 is flowed in i.e. and is led in the interior gap for flowing atomizer 4 between the atomizer 8 that outflows
Gap between the side wall in hole 15) be 50-80 i.e. 0.5-0.8mm when, it is interior stream atomizer 4 ejection vapor stream it is more steady
It is fixed, while also can preferably break up the cooling water of the ejection of spiral nozzle 11, keep the droplet particle of cooling water smaller, atomizing effect compared with
It is good.
Further, the lower section of deflector hole 10 is equipped with deflector hole internal screw thread 9, and the upper end of spiral nozzle 11 is equipped with external screw thread,
Spiral nozzle 11 is threadedly coupled with deflector hole 10, facilitates the installation and removal of spiral nozzle 11.
Further, gasket 12 is provided between the lower end of mounting flange 7 and the upper end for the atomizer 8 that outflows.Gasket
12 preferably graphite material, serve sealing with it is through-flow.
Further, through-hole 15 is stepped hole, and the diameter of the upper section of through-hole 15 is greater than the diameter of the lower section of through-hole 15, interior stream
The shape of the outer wall of atomizer 4 is corresponding with through-hole 15, and steam leads to ring 16 and interior stream mist corresponding with the upper section of through-hole 15 is arranged in
On the outer wall for changing nozzle 4.
