Further, aforesaid a kind of gas-liquid double fluid atomization nozzle device, the outer cylinder surface of shower nozzle is provided with rectangular thread.
Further, aforesaid a kind of gas-liquid double fluid atomization nozzle device, shower nozzle stretches out nozzle boss.
Further, aforesaid a kind of gas-liquid double fluid atomization nozzle device, air inlet pipe and nozzle are respectively equipped with branch sleeve outward, and branch sleeve is connected by screw rod with nozzle boss.
Further again, aforesaid a kind of gas-liquid double fluid atomization nozzle device, joint is provided with nut a outward, and nut a is connected with joint screw thread, and the top of nut a is provided with nut b, and nut b is fixedlyed connected with nut a by dog screw.
Further, aforesaid a kind of gas-liquid double fluid atomization nozzle device, nut a is circumferentially with groove, and dog screw is screwed into the screwed hole of nut b, and head inserts in the groove of nut a.
The beneficial effects of the utility model are: gas-liquid double fluid atomization nozzle device of the present utility model, when atomization gas enters the shower nozzle place by air inlet pipe, because the sudden contraction of the cross section that gas passes through, gas speed will sharply increase, and in nozzle boss, form gas eddy, make feed liquid under the impact of high velocity air, form the atomizing feed liquid.This device has improved the effect of feed liquid atomizing, and shower nozzle stretches out nozzle boss, has avoided scabbing at the shower nozzle place.

The specific embodiment
Below in conjunction with Figure of description and the specific embodiment the utility model is described in further detail.
Fig. 1 shows the structural representation of a kind of gas-liquid double fluid atomization nozzle of the utility model device, this device comprises feed pipe 9, one end of feed pipe 9 is connected with an end of joint 4, the other end of joint 4 is connected with charging aperture 11, the feed pipe 9 outer air inlet pipe 10 that are provided with, have air inlet 12 on the air inlet pipe 10, the other end of feed pipe 9 is provided with shower nozzle 7, the end of shower nozzle is provided with nozzle, the shower nozzle 7 outer nozzle bosses 6 that are provided with, one end nozzle boss 6 of air inlet pipe 10 connects, and the other end is connected with taper one end of conical sleeve, and the conical sleeve inboard is provided with packing seal 3.
As can be seen from Figure, outside joint 4, be provided with nut a1, nut a1 is connected with joint 4 by the mode that is threaded, the top of nut a1 is provided with nut b2, and nut b2 is fixedlyed connected with nut a1 by dog screw 8, at the groove that is circumferentially with of nut a1, dog screw 8 is screwed into the screwed hole of nut b2, the come in and go out groove of nut a1 of head, as shown in Figure 2, the axial location of the position-adjustable shower nozzle by circumferential adjusting nut b.
One end of nozzle boss 6 is fixedlyed connected with nozzle, is respectively equipped with branch sleeve 13 outside nozzle and air inlet pipe 10, and branch sleeve 13 is connected by screw rod 5 with nozzle boss 6.Nozzle boss 6 is realized the fixing of circumferential and axial by screw rod, by screwing nut, can regulate the axial location of nozzle boss 6.Packing seal 3 is air inlet chamber one end sealing, can only flow to shower nozzle 7 directions after making gas enter air inlet pipe by air inlet 12.When gas enters air inlet pipe 10 when flowing to shower nozzle 7 places, because the sudden contraction of gas passage cross section diminishes, gas speed will increase a lot, gas is by forming the gas eddy of rotation in nozzle boss 6 after the shower nozzle 7, feed liquid is broken into droplet under the impact of high velocity air, form the atomizing feed liquid.
The core component of spray nozzle device is nozzle boss 7 and shower nozzle 6, and is higher to concentricity requirement.If concentricity is not good, gas vent annular space inequality then, the droplet size that produces behind the solution atomization is just inhomogeneous.In order to guarantee the axiality between nozzle boss 6 and the shower nozzle 7, cylindrical cavity and shower nozzle 7 outer cylinder surfaces adopt the higher loose fit of ratio of precision in the nozzle boss 6, shower nozzle 7 outer cylinder surfaces are provided with rectangular thread, and as shown in Figure 3, air formed the whirlpool of rotation when atomization gas was by shower nozzle like this around the shower nozzle conical surface.Because atomization gas pressure, gas liquid ratio are very big, during air-flow ejection nozzle boss, mix with feed liquid, feed liquid is smashed, reach the atomizing purpose.
During nozzle operation, shower nozzle 7 taphole end faces stretch out nozzle boss 6 end faces one segment distance a for best, as shown in Figure 4, wherein, be 0-1mm apart from the general value of a, the general value of ejection angle [alpha] of shower nozzle is the 60-120 degree, and the size of nozzle width d and shower nozzle width D is determined according to the flow of gas liquid, d gets 3.5mm in the present embodiment, and D gets 5.5mm.If the shower nozzle end face reaches the nozzle boss front end face or contracts in nozzle boss inside, cause shower nozzle to scab easily, can the plug nozzle gas liquid outlet when serious.
Spray nozzle device of the present utility model is used in the denitration fluid bed UO
