Description
The utility model relates to a kind of injection apparatus, the especially a kind of two-phase effervescent atomization nozzle that can regulate.
Existing nozzle internal structure all is fixed, and two kinds of pressure atomization and pneumatic nebulizations are generally arranged, and corresponding nozzle is referred to as pressure atomization nozzle (or claiming the mechanical atomization nozzle) and pneumatic spraynozzle.The former makes liquid obtain enough kinetic energy by pressure and is ejected in the relative static air with the pressure of liquid self power as atomizing, and fluid column or liquid film unstability, separation, fragmentation become tiny liquid grain, realizes atomizing.The latter introduces the atomizing medium (gas) with energy in nozzle, utilize gas as power, acts on liquid, with the atomization of liquid.The introducing and the mode of action according to gas are divided into pneumatic outer mixed pneumatic interior mixing again.Pneumatic outer mixing is that gas is quickened in gas circuit, rotates, and acts on spray and makes its atomizing from the liquid of nozzle.Mixing in pneumatic is that gas is mixed in nozzle, acts on earlier with liquid, realizes primary atomization, and ejection is gone again, realizes secondary-atomizing.No matter from atomization mechanism, atomizing effect and adaptability, pneumatic nebulization all is better than pressure atomization, therefore obtains great development and uses.More advanced effervescent atomization nozzle has appearred again in recent years, control gas-liquid mixed ratio when its characteristics are to design, make it remain on the gas-liquid two-phase bubbly flow attitude, and the size and the uniformity of control bubble, with the bubble explosion as atomizing power, thereby the liquid mist that obtains thinner particle, is more evenly distributed.Theoretically, this mechanism is advanced, but owing to the research to two phase flow at present just begins, still is in the exploratory stage, makes the nozzle design run into very big difficulty.In order to solve above-mentioned difficulties, special the utility model patent, the promptly adjustable two phase flow effervescent atomization nozzle of proposing.Even under the condition that changes of condition or under unpredictable situation, utilizing regulating spool to change nozzle has related parameter, making atomizing reach optimum efficiency at the scene.
The utility model purpose provide a kind of be fit to various operating modes, atomizing very good, the adjustable completely two-phase effervescent atomization nozzle of burning, realizing one, to chew many usefulness, material-saving, fuel-economizing, life-span long.
The technical solution of the utility model is achieved in that adjustable two-phase effervescent atomization nozzle is linked in sequence by adjustable column cap, gun platform, outer tube, interior pipe, adjustable spool and shower nozzle successively and forms, it is characterized in that: the internal thread of gun platform is connected with the external screw thread of adjustable column cap, the upper end of adjustable column cap and interior pipe, adjustable spool link together, rotating adjustable column cap moves up and down in pipe can make in it pipe and adjustable spool, make that two phase flow reaches the air bubble-shaped fluid in the chamber, and atomizing better.
Above-mentioned interior pipe and adjustable spool are to be threaded or to weld adjustable spool top gas jet angle α=30 °～120 °.
That above-mentioned shower nozzle and sprinkler cap can make integral type or screw-type, the last top end face of sprinkler cap is flat-top (180 °) or is the vertex of a cone, its cone angle beta=30 °～150 °, or be hemisphere face, that the axis of the spray orifice on its face and end face have is vertical, have be inclination, form alternate staggered injecting type, it is best to reach atomizing, the particulate minimum.
That above-mentioned interior pipe can make integral type or make two articulated elements and connect together; The entrance point of adjustable column cap links to each other with snap joint.
The beneficial effects of the utility model:
1,,,, realizes that one chews many usefulness to reach the purpose that burning is complete, reduce pollution, fuel-economizing so it is applicable to various duties, and can be transferred to best spray pattern because this effervescent atomization nozzle is adjustable.
2, because the sprinkler cap of this effervescent atomization nozzle is removable, thus be subjected to ablating afterwards or the sprinkler cap that is easy to more renew after the wearing and tearing, and remainder still can use, and realizes that body portion can use for a long time.
3, owing to adopted the snap joint connection, make disassemble and assemble work convenient, rapid.
