Description
Technical field
The invention belongs to gas-liquid two-phase fluid conveying means in the pipeline, relate in particular to a kind of pipeline that is used for the conveying gas gas-liquid two-phase liquid and play cyclone.
Background technique
Spiral flow is a kind of liquid form with rotational flow field, and it is extremely extensive in the application area of industrial aspect, in hydraulic engineering, in the machining, application is arranged all.Simultaneously, the spiral flow technology has also got into people's daily life field, like energy-conservation gas ring of spiral flow etc.Use since spiral flow has so widely, its generation condition is just very crucial so.In general, the conventional production method of spiral flow has three kinds: tangential influent stream, installation guide plate and rotating pipe.
The spiral flow generating means that the water conservancy diversion chip is installed is to produce spiral flow through changing pipe current boundary conditions; Several fixing guide vanes that promptly have certain laying angle in the setting of pipeline section inwall; When current pass through this pipeline section; Current not only travel forward vertically, and have produced circumferential movement, and the resultant motion of the two has just formed spiral flow.But shortcoming is also many: installation precision is had relatively high expectations, and the intensity of spiral flow awaits improving, and energy consumption is higher, and decay is very fast; Dependence is stronger to external world, and concerning gas-liquid two-phase fluid, the mixed effect of ginseng is undesirable, and (A Erge is thunder A. H. not, than Ha Dewa R. K.; The turbulent flow measurement Research of decay spiral flow in the rich YVN. pipe. applied science research, 1988, Vol. 45; 233～250. and Ahmadinejad A. S, the unexpected tubular inflation flow field of axisymmetric characteristic research under the different spiral intensity distriubtion of A Maide S. A.. international heat flows 1992 with fluid; Vol. 13, No. 4,314～321.).In addition, the mode of cast nozzle also can produce spiral flow, and promptly the mode through the tangential influent stream produces circumferential speed; Produce spiral flow with axial velocity stack, but its shortcoming be complex structure, need often safeguard, need to guarantee nozzle location parameter (Qi Geer N. A, the experimental research of helical swirl motion on the Qian Wensiji A. jet airplane. the applied mechanics journal; 1967, Vol. 34,443～451. and Sen Pai such as E. M; But card ripple A. pipe internal spiral flows and hot transfer study. the international heat transfer; 1984, Vol. 106,766～773.).Therefore, said method can not satisfy actual gas-liquid two-phase and works the requirement of revolving.
In addition, the spiral flow generating means that also has other.Nineteen ninety, Kiyoshi professor Horii of day raw white lily woman university has proposed a kind of self-generating spiral flow generating means, the inventor be the air that utilizes as flowing medium, be respectively 1.0 * 10 at reynolds' number
5With 1.6 * 10
5Under two kinds of conditions, the influent stream mode of injecting through aperture radial centripetal in the axisymmetric face demonstrates the existence of spiral flow with particle, and has obtained F.P. (No. 0456931) and U. S. Patent (No. 4721126) (great auspicious K; Maas distant nurse Y., old X. M., Tyke M.; Haas three of the special B. spiral flow research that rubs: the opening of fiber and orientation research, Japan Airlines' space research, 1990a under the spiral flow form; 32 (98)); But complex structure, difficult installation is unfavorable for the application on experimental situation and the engineering.And the spiral flow circumferential speed that produces is little, and spiral flow is unstable and decay is very fast, talks about for gas-liquid two-phase fluid and revolves that to mix effect not high with ginseng.Therefore, said method does not meet the demands yet.
