First, patent " vortex generator " (200620068646.4, open (bulletin) number CN 2869720Y) provide a kind of vortex generator, comprise round steel pipe, round steel and four helical blades, four helical blades are distributed on the surrounding of round steel, inwall that the other end is arranged on round steel pipe its one end by same rotation direction, helical blade and round steel axially at 45 °.This device can produce spiral flow and improve the transfer efficiency of fluid, but this device also exists some shortcomings: inconvenience is installed, does not relate to the Placement of round steel pipe and pipeline in the description of patent; In addition, intensity is not high, and patent is that four blades are arranged on inwall, when there being slurry stream out-of-date, can cause very large impact to blade.In addition, patent " is used in the axial-flow fluid vortex generator on pipe-line " (200910022760.1, open (bulletin) number CN 101603628A) be a kind of device of gas mixture fluid, be used in the axial-flow fluid vortex generator on pipe-line, by entrance point, shell, outlet end, linked into an integrated entity; There is in the enclosure one group of device being formed by connecting by inlet guide flow cone, helical blade, intermediate, outlet guide flow cone; Helical blade the inner is fixed on intermediate, and outer end is fixed on shell.This invention can make mixture fluid mode with spiral and layering in pipeline flow, be applicable to paraffin in pipeline and the conveying of scale deposition amount, also be beneficial to cleaning wax deposition incrustation, but also there is obvious defect in this invention: 1. helical blade is thinner, is unfavorable for fixing.Its intermediate is to fix by helical blade, and when have the class solid fluids such as slurry by time can cause large impact to intermediate, thereby damaged blade likely.2. this device is case type, and inner difficulty of processing is large, is unfavorable for actual popularization.The problems such as just current, although there is more helical flow generating device, all ubiquity spiral effect is bad, the not high and processing difficulties of impact strength, therefore, said method all can not meet the demands.
Summary of the invention
The object of the invention is for solving the demand of scientific experiment and Practical Project, and on the basis of comprehensive various device advantages in the past and invention a kind of efficient, continuously and the spiral flow of low energy consumption occur and feedway.By finned the rising of novel circular cone, revolve mode, the spiral flow successful that device is produced, spiral flow flow pattern keeps better.In addition, adopted the form of fastening flange, made this device be easy to install.Finally, this device does not need to add other energy consumption equipment, is applicable to widely experiment and Practical Project field about spiral flow.
Circular cone type spiral flow generator of the present invention, is comprised of flange, cylindrical shell and fin three parts, and wherein, flange is provided with bolt hole, for make this generator be connected with pipeline to be connected by bolt; Described cylindrical shell hypomere is cylindrical tube, and epimere is conical type tube body, and the internal diameter of cylindrical tube is identical with internal diameter of the pipeline waiting, and cylindrical tube end is fixedly connected with flange; The bottom surface inner diameter D of divergent-cone wall is identical with cylindrical tube, and conical tube height h is 1:1～1:2 with the ratio of bottom surface internal diameter, and its cone angle is β, β=2arctan (D/2h); Conical tube surface is evenly distributed with flowing hole along the conical surface, and described fin arranges on conical tube surface, the outside of flowing hole, and the angle [alpha] of fin bottom surface and flowing hole plane is 30 °～60 °.
In such scheme, described flowing hole quantity is 3～6; Flowing hole is rectangle, and long limit is parallel with divergent-cone wall bus, length is bus length 0.4～0.7 times, and from the vertex of a cone, the distance of the one end close to and bottom surface is bus 0.1～0.2 times, minor face is parallel with bottom surface, length is to grow 0.2～0.4 times of limit.
In the present invention program, described fin is also one of critical piece producing spiral flow, the scalariform body that can be comprised of cuboid and triangle body; What contact with flowing hole is cuboid, and the other end is triangle body; The long limit of cuboid is identical with the long limit of flowing hole, and bond length is 0.2～0.4 times of long limit, is highly 0.2～0.3 times of minor face; The triangular facet of triangle body is connected with the plane that flash forms with the broadside of cuboid, and its axial cross section is isosceles right triangle.The scalariform body being formed by cuboid and triangle body, the angle [alpha] of its bottom surface and flowing hole plane is 30 °～60 °, and angle is less, and spiral intensity is higher.
As concrete example, wherein, flange thickness is 1～2mm, and flange surface has 4 equally distributed bolts hole, by bolt, this new device is firmly connected with pipeline to be connected.About cylindrical tube, its cylinder internal diameter is identical with internal diameter of the pipeline waiting, and axial length is 5～20cm, and cylindrical shell thickness is 2-5mm.About divergent-cone wall, it is one of critical piece producing spiral flow, its bottom surface inner diameter D is identical with cylindrical tube, cylindrical shell conical surface thickness is identical with cylindrical tube body thickness, be 3～5mm, conical tube height h is 1:1～1:2 with the ratio of bottom surface internal diameter, and along with the increase of its ratio, the intensity that spiral flow produces can become large gradually; Its cone angle is β, β=2arctan (D/2h).
This Novel spiral flow generating apparatus novel structure, easy for installation, spiral intensity is high.During use, this Novel spiral flow-generator is connected on official road.Transportation of substances in general pipeline has: oil, air, rock gas, water and sludge etc.When mixture fluid is with pressure while being entered by divergent-cone wall inside, mixture fluid will flow through from flowing hole.The fluid being flowed out by flowing hole can make fluid produce circumferential speed through the effect of conical tube surface fin, and mixture fluid becomes strong spiral motion from original axial motion like this.Avoided like this sludge and other materials to stick on pipeline, caused pipeline obstruction and cause fluid ability to decline.In the pipeline of long distance, there will be the decay of kinetic energy, in order to prevent that conveyance capacity from declining, and should arrange a Novel spiral flow-generator every a segment distance (2～5Km) on pipeline.In addition, according to carrying the material proportion of fluid and the difference of kind, can adjust the size of angle [alpha] of fin bottom surface and flowing hole plane to raise the efficiency.And this device need to not add any power after mixture flow, by kinetic energy originally and the centrifugal force of generation, can realize spiral and axial flow, reduce the dependence to external power in way.Finally, this device is connected with pipeline closed, and finishing is simple, safe and reliable to operation.
The present invention adopts finned of novel circular cone to revolve, novel structure, and spiral effect is good, and spiral intensity is large.Adopt the form of retaining washer, make integral body be easy to install.The energy consumption equipment that does not need to add other, energy consumption is low.
