Description
Technical field
What the present invention relates to is a kind of atomising device, specifically a kind of hyperacoustic pressure rotary-atomizing nozzle that has been coupled.
Background technology
Super-fine atomization is to realize one of prerequisite that the gas turbine wet compression technology is widely used and key technology.In the Wet Compression process, the size of drop has directly determined the service behaviour of Wet Compression system, has only the drop that is evaporated fully just can make the maximum potentiality of Wet Compression system performance.Drop is too big, except can not evaporating fully, and the impeller of bigger drop meeting percussive pressure mechanism of qi, the service life of shortening compressor.This just requires to develop a kind of novel atomizer can produce the Suo Te diameter at the droplet of several microns to tens microns, to satisfy the requirement of Wet Compression.
The pressure swivel nozzle is that a kind of eddy flow spare of nozzle interior that utilizes makes liquid produce rotation at a high speed, and in the passage of convergence, quicken to spray, form the atomizer of hollow taper liquid film so that atomizing, be characterized in that the droplet Suo Te diameter that forms is less, it is comparatively even to distribute, its shortcoming is little after to a certain degree at the Qi Suote diameter, needs high expulsion pressure if think further to reduce drop size.For the further droplet sizes that reduces the pressure swivel nozzle, and consider that the pressure swivel nozzle is a kind of liquid-sheet atomization, ultrasonic wave is coupled in the pressure swivel nozzle.By the spreading of spray of meticulous controlled pressure swivel nozzle, the dither by ultrasonic transducer generating is directly affacted on the formed liquid film of pressure swivel nozzle, can realize further atomizing.
The open report relevant with the present invention has: disclosed technical scheme in these three parts of patent patent documents of JP4169705 (A) JP4169704 (A) and JP4169703 (A), and what be primarily aimed at is the combination of simple direct-injection type drive nozzle and ultrasonic nozzle; Mentioned three in the patent document of US 3784105 (A), GB 941181 (A) and GB 1355647 (A) and turned to the master, added a technical scheme that can make the nozzle of the small cap that liquid in rotation gets up at liquid outlet with ultrasonic fog.
Summary of the invention
The object of the present invention is to provide a kind of ultrasonic wave and pressure rotary atomizer that the ultra-fine droplet of Suo Te diameter between several microns to tens microns can be provided for gas turbine Wet Compression system.
The object of the present invention is achieved like this:
Comprise ultrasonic transducer and two parts of pressure rotating liquid spout; Described ultrasonic transducer comprises transducer back shroud, pretension bolt and nut, piezo-electric crystal and nozzle protecgulum; Described pressure rotating liquid spout comprises drainage part, pad, eddy flow spare and nozzle head; Piezo-electric crystal steps up between nozzle protecgulum and transducer back shroud by pretension bolt and nut; Nozzle head is installed in the drainage part and places nozzle protecgulum front end, and drainage part and eddy flow spare place nozzle head, and drainage part and eddy flow spare therebetween pad have the O RunddichtringO between nozzle head and the nozzle protecgulum; Have the spin chamber in the middle of the eddy flow spare.
The present invention can also comprise:
1, there is the convergent runner of a taper spin chamber in the middle of the eddy flow spare, and eddy flow spare side has pod apertures, and the opening direction of described pod apertures is vertical tangent with spin chamber's internal face, and the number of pod apertures is 1-4, is uniformly distributed in eddy flow spare side.
2, the drainage part is one-sided fluting, and the ratio of groove width and groove depth is 1.5-2.5.
3, the operating frequency of ultrasonic transducer is at 40kHz-120kHz.
4, nozzle head is opened conical bore.
The material that eddy flow spare among the present invention, pad, drainage part and nozzle former piece use is high-class stainless steel, and other parts get final product with high pressure resistant steel alloy.
The present invention invents according to the capillary ripple mechanism of the liquid-sheet atomization mechanism of pressure swivel nozzle and ultrasonic atomizatio.
The liquid-sheet atomization mechanism of pressure swivel nozzle thinks that the liquid that sprays from the pressure swivel nozzle exists with hollow taper liquid film form, under the effect of the pneumatic power of dragging of surrounding medium, small sample perturbations on the liquid film is exaggerated, form bigger disturbance, be subjected to the influence of big disturbance, the liquid film surface can produce significantly fluctuation, this liquid film instability, be easy to produce brin, finally form drop.
The capillary ripple mechanism of ultrasonic atomization is when liquid film flows through the surface of solids of dither, can form capillary ripple on the surface of liquid film, and the crest of capillary ripple just forms tiny drop after the surface tension constraint of having requested liquid.
In conjunction with these two mechanism, specific practice is as follows: liquid is at first by the drainage part, depart from the center, flow through cyclone then, produce the liquid film of rotation at a high speed, after the ultrasonic transducer energising electric energy is converted into the vibrational energy of the surface of solids, the vibration meeting of the surface of solids can produce extremely strong disturbance to liquid film, thereby increase the turbulence energy of atomizing, improve atomization quality.
Atomising device provided by the invention can further produce the Suo Te diameter and be several microns drops to micron on the basis of pressure swivel nozzle, overcome the pressure swivel nozzle at the little pressure bottleneck after to a certain degree of drop size.
Compare with disclosed technical scheme in this patent patent document of JP4169705 (A) JP4169704 (A) and JP4169703 (A), this patent adopts the pressure rotating nozzle to combine tangible difference with ultrasonic nozzle; Compare with disclosed technical scheme in the patent document of US 3784105 (A), GB 941181 (A) and GB 1355647 (A), the present invention is as main atomizing means with the pressure rotary-atomizing, ultrasonic wave is as supplementary means, this requires the present invention at first to consider the design of spin chamber when design, the design of eddy flow spare+pad+conducting element improves operating pressure of the present invention greatly, fully makes the advantage of pressure rotary-atomizing obtain performance.On this basis, be aided with action of ultrasonic waves, make the present invention can reach the requirement of Wet Compression mist droplet particle size.
