Specific embodiment
Gas-liquid two-phase multistage atomizing nozzle described in the utility model is made into one in the following with reference to the drawings and specific embodiments
Walk explanation.
As shown in Figures 1 to 3, gas-liquid two-phase multistage atomizing nozzle described in the utility model is included outside the nozzle equipped with inner cavity 11
Shell 1, inner cavity 11 is cylinder, and the top and bottom of nozzle housing 1 are respectively equipped with air inlet 12 and dispersive nozzle 13, it is special it
It is in further including the atomization core 2 being co-axially located in inner cavity 11 and collection chamber 3.
Atomization core 2 includes the atomization core body 21 equipped with spray chamber 211 and the inlet tube positioned at 21 top of atomization core body
22.Spray chamber 211, which is equipped with, to be connected with inner cavity 11 and positioned at the atomisation outlet 2111 of 13 top of dispersive nozzle.Atomization core body 21 is in
Column, top are equipped with the delivery hole 212 that multiple both ends connect respectively with spray chamber 211 and inlet tube 22, and side wall is equipped with multiple
The gas port 213 that both ends connect respectively with inner cavity 11 and spray chamber 211,21 bottom of atomization core body are in rounding mesa-shaped and and nozzle
Annulus 4 is equipped between the bottom inside of shell 1.The tube wall of inlet tube 22 is fixedly connected with nozzle housing 1 and inlet is located at
1 top of nozzle housing is outer.Collection chamber 3 include being set in inlet tube 22 is outer and upper end is connected with 1 inside top of nozzle housing every
From the annular partition 32 that cylinder 31, inside edge and outer ledge are connected respectively with 22 outer wall of inlet tube and 31 bottom of isolating cylinder, every
Venthole 311 is provided on side wall from cylinder 31.
The width at the most narrow place in annulus 4 is less than the spacing in 21 outside of atomization core body and 1 inside of nozzle housing.
Above-mentioned atomizer is from top air inlet and feed liquor, and inside changes the flowing side of gas with the collection chamber 3 set
To, so as to the air intake structure from setting complexity in 1 side of nozzle body, help to simplify the external structure of nozzle body 1, and
Convenient for the transport and installation of atomizer.The narrow throat of Laval nozzle is equivalent at the relatively narrow annulus 4 of nozzle interior, is had
Help accelerate the air-flow near dispersive nozzle 13 and promote atomizing effect.
Rear portion is discharged through venthole 311 enter spray chamber 211 through gas port 213 into the air-flow in collection chamber 3, after
It is discharged from 211 bottom of spray chamber, another part is then via gap of 21 outside of atomization core body with 1 inside of nozzle body and annular
Gap 4 crosses with discharging the gas of spray chamber 211, then discharges nozzle housing 1 through dispersive nozzle 13 together.In inlet tube 22
Liquid to be atomized enters spray chamber 211 and the suction function inside spray chamber 211 via multiple more elongated delivery holes 212
Lower realization is atomized for the first time, and the droplet of generation via gas stream make impact of the gas port 213 into spray chamber 211 with realizing second
Secondary atomization finally flows through the air-flow at annulus 4 and impact rotary-cut is further carried out to the droplet for discharging spray chamber 211 so as to reality
Now third time is atomized.Above-mentioned atomizer contains three-level atomization mechanism, and atomizing principles at different levels differ, and can make liquid
Atomization is more abundant.In addition the structure of atomizer is relatively simple, and the shape of each building block is more regular, system easy to process
Make.
The bottom of spray chamber 211 is the diversion cavity 2112 of a reverse frustoconic.Narrowed diversion cavity 2112 contributes to droplet
Accelerating Removal spray chamber 211 acts on its impact rotary-cut so as to aggravate air-flow at annulus 4.
Multiple spiral helicine guide vanes 214 are equipped at intervals on the inner wall of diversion cavity 2112.Flow through the mist of diversion cavity 2112
Acceleration can be further rotated by, which dropping under the action of guide vane 214, goes out spray chamber 211, aggravates itself and air-flow at annulus 4
Rotary-cut impact, and then promoted atomizing effect.
Venthole 311 is respectively to be tangentially disposed in positioned at the opposite sides and venthole 311 of inlet tube 22 with air inlet 12
On the side wall of isolating cylinder 31.So air-flow can be through tangential discharge of the venthole 311 along isolating cylinder 31, so as to reduce air-flow to nozzle
The impact of 1 inner wall of shell is conducive to maintain the stabilization of air-flow.
Multiple gas ports 213 are round taper hole, and conical gas port 213 is helped speed up into spray chamber 211
Air-flow velocity aggravates the mutual collision of air-flow and drop, promotes atomizing effect.
Multiple gas ports 213 are set for multilayer, and every layer of gas port 213 is the side wall for being radially arranged in atomization core body 21
On, so contribute to the abundant effect of air-flow and drop.
