Embodiment
As shown in Figure 2, be steam atomization formula jet rose apparatus structure schematic diagram, described steam atomization formula jet rose device is made up of water-in flange 1, admission flange 7, water spray ingress pipe 8, nozzle body 9, jet chimney 10, atomizer body 11, steam jet 12 and desuperheating water nozzle 13.Nozzle body 9 is located on the jet chimney 10, be provided with steam pipework in the nozzle body 9, the steam pipework middle part is provided with water spray ingress pipe 8, nozzle body 9 connects atomizer body 11, be provided with steam jet 12 and desuperheating water nozzle 13 in the atomizer body 11, steam jet 12 and desuperheating water nozzle 13 are connected with steam pipework and water spray ingress pipe 8 respectively.
As shown in Figure 3, be the steam jet structural representation, described steam jet 12 comprises steam jet main body 19, be provided with steam squit hole 14 and desuperheating water passage 15 in the steam jet main body 19, the inlet of steam squit hole 14 and desuperheating water passage 15 connects steam pipework and water spray ingress pipe 8 respectively, as shown in Figure 4, be desuperheating water nozzle section figure, described desuperheating water nozzle 13 comprises desuperheating water nozzle body 20, one end of desuperheating water nozzle body 20 is provided with desuperheating water inlet 17, and the other end is provided with water spray aperture 18, as shown in Figure 5, be desuperheating water nozzle arrangements schematic diagram, be provided with desuperheat tank 16 in the desuperheating water nozzle body 20, desuperheat tank 16 1 ends connect desuperheating water inlet 17, and the other end connects water spray aperture 18, the outlet of desuperheating water passage 15 connects desuperheating water inlet 17, and the outlet of steam squit hole 14 connects water spray aperture 18.The quantity of steam squit hole 14 equates with water spray aperture 18 quantity.Steam squit hole 14 is concentric with water spray aperture 18.The aperture of steam squit hole 14 is not more than 2/3 of water spray aperture 18 apertures.The bearing of trend of desuperheat tank 16 is the tangential direction of water spray aperture 18, guarantees that current tangentially flow into along the aperture wall, the rotation ejection.The central lines of the center of atomizer body 11 and jet chimney 10, jet chimney 10 perforates should be satisfied: atomizer body 11 can be guaranteed accessible putting into.
