Going out of described electric hybrid module 3Mouth is communicated with spray assembly 5. The described part that smashes target nail 4 is interted in electric hybrid module 3,Smash for the water that water inlet component 2 is imported. Can pass through air intake assembly 1, water inlet component2 carry out respectively air feed and water supply, adopt the design of two-fluid internal mix, can make liquid phase mixReach the requirement of the spraying granule of large particle diameter icing wind tunnel.
Described air intake assembly 1 comprises and connects gas head 11 and wireway 12. Described connect gas head 11 canFor being connected with extraneous air feed equipment. The inlet end of described wireway 12 with connect gas head 11 and be connected.The outlet side of wireway 12 is communicated with the hybrid chamber 30 of electric hybrid module 3. Described wireway 12Internal diameter be 0.5-0.9mm. Described water inlet component 2 comprises connecting waterhead 21 and water inlet pipe 22.Described connecting waterhead 21 is for being connected with extraneous water supply installation. The import of described water inlet pipe 22 withConnecting waterhead 21 connects. The outlet of water inlet pipe 22 is communicated with the hybrid chamber 30 of electric hybrid module 3.The internal diameter of described water inlet pipe is 0.5-0.9mm. Can be by wireway 12 and water inlet pipe in the present embodiment22 adopt isometrical setting, and both internal diameters are 0.5-0.9mm, thus can make gas withWater to enter amount less, can more favourable transfer gas-liquid amount recently control the size of granularity.
Described electric hybrid module 3 comprises the first mixing duct 31 of inner hollow and inner hollowThe second mixing duct 32. Described the second mixing duct 32 and the inner phase of the first mixing duct 31Intercommunicated. The internal diameter of described the second mixing duct 32 is greater than the internal diameter of the first mixing duct 31.The internal diameter of described the first mixing duct 31 is greater than the outlet internal diameter of air intake assembly 1. Described firstThe described hybrid chamber 30 of the common formation in inside of mixing duct 31 and the second mixing duct 32.
Described the first mixing duct 31 is connected with air intake assembly 1. Described the second mixing duct 32Be connected with described water inlet component 2. The described target nail 4 that smashes is connected with the second mixing duct 32,And the part that smashes target nail 4 is interted in the second mixing duct 32. In the present embodiment, smashTarget nail 4 parts of interting in the second mixing duct 32 can with the water inlet pipe of water inlet component 2 22Alignment arranges, and while making water enter hybrid chamber 30 by water inlet pipe 22, run into and smash target nail 4,Because making water, the effect of percussion power is crashed to pieces.
Described spray assembly 5 comprises storage vaporware 51 and nozzle 52. Described nozzle 52 is installed onOn storage vaporware 51. Described storage vaporware 51 inside start to have storage mist chamber 50. Described storage mist chamber 50Diameter large compared with the internal diameter of hybrid chamber 30, store up the internal diameter in mist chamber 50 compared with the first mixing duct31 and the internal diameter of the second mixing duct 32 all large. In the present embodiment, gas is by wireway 12Successively through the first mixing duct 31, the second mixing duct 32 and storage mist chamber 50, due to air guideThe internal diameter in pipe 12, the first mixing duct 31, the second mixing duct 32 and storage mist chamber 50 is from littleArrange to large, the aerosol of gas or gas-liquid mixed is fallen successively at transmitting procedure medium velocityLow, thus pressure is increased gradually, and what make that water mixes with gas is more reasonable, and makesNozzle 52 reaches desirable particle diameter the effect of ejection water smoke is better.
In order better to realize spray effect, can be V-arrangement nozzle by described nozzle 52. DescribedNozzle 52 is U-lag with the part that storage mist chamber 50 contacts. U-shaped groove and V-type nozzle 52Tangent part is semicircle opening. In the time that water smoke touches U-shaped groove, due to U-shaped groove twoThe pressure on limit is large compared with semicircle opening part, water smoke is pushed to the import of nozzle 52 to nozzle 52Space, place is less, and therefore the large pressure of aerosol flow velocity at this place is little, makes water smoke at nozzle 52 places,Fragmentation makes the ejection more uniformly of gas-vapor mix again, can effectively control the grain of spraying granuleFootpath.
A kind of twin method is also provided in embodiments of the invention, two by the aboveFluid spray device carries out atomization, and atomization process comprises: water supply air feed steps A, smash stepB, blend step C and spray step D, the each step of above each A-D in no particular order.
Described water supply air feed steps A can comprise: by 2 points of air intake assembly 1 and water inlet componentsDo not carry out air feed and water supply to the hybrid chamber 30 of electric hybrid module 3. The described step B that smashes can wrapDraw together: after the water that water inlet component 2 feeds enters hybrid chamber 30, undertaken by smashing target nail 4Smash. Described blend step C can comprise: air intake assembly supplies 1 gas entering by air inlet groupThe outlet of part 1 enters after electric hybrid module 3, and gas is tentatively mixed to form with the water being crashed to piecesWater smoke. Described spray step D can comprise: preliminary mixed water smoke is in spray assembly 5When storing and passing through the nozzle ejection of spray assembly 5, because nozzle is that V-arrangement nozzle makesObtain aerosol and can again smash mixing, thereby can make the water smoke particle diameter of ejection more meet icingThe requirement of wind-tunnel.
As preferred embodiment, by water supply air feed steps A to spray step D: described in enterStorage mist chamber 50 internal diameters of outlet, hybrid chamber 30 and the spray assembly 5 of pneumatic module 1 increase successively;Gas is entered by the outlet of air intake assembly 1 in the process in storage mist chamber 50 of spray assembly 5, gasThe speed of body motion progressively reduces, can be large according to the little pressure of gas flow rates, and gas flowThe principle that the large pressure of speed is little, makes the pressure in the storage mist chamber 50 of spray assembly 5 be greater than mixingThe pressure in chamber 30. Because pressure difference between the two can further improve mixing of water and gasThe uniformity.
As preferred embodiment, the internal diameter of V-arrangement nozzle 52 import departments of described spray assembly 5Be far smaller than the internal diameter in storage mist chamber 50. Water smoke is through in the storage mist chamber 50 of described spray assembly 5Enter V-arrangement nozzle 52 time; The flow velocity of water smoke increases, and pressure is diminished, because of nozzle waterThe flow velocity of mist makes the water smoke tentatively mixing again smash mixing with the conversion of internal pressure.
In embodiments of the invention, gas sprays by water inlet pipe 22 and runs into and smashes target nail, because ofThe effect of percussion power makes water column fragmentation. Gas is blown into by wireway 12, through hybrid chamber 30Enter into the storage mist chamber 50 of spray assembly 5, make progressively reduction of speed of air-flow because internal diameter progressively increases,The decline of gas impulsive force and make the water particle can be by complete atomization, obtains the water particle of greater particle size.Gaseous mixture liquid flows into storage mist chamber 50, because the larger pressure of internal diameter in storage mist chamber 50 is large and connect VShape nozzle 52, can be little according to the space of V-arrangement nozzle 52 import departments, and aerosol flowing velocity is fast,Can make the broken and mixing again of super-size water particle. In the present embodiment, the angle of V-arrangement nozzle canIt is 30 °-75 °.
