The turbolator of the invention has the advantages of compact structure and convenient installation and use. The laboratory experiment research shows that the turbolator can reduce the resistance of the bent pipe by about 10%.
Description
Technical field
Energy-saving anti-corrosive equilibrium flow field turbolator of the present invention relates to a kind of bend pipe flow field balace weight, mainly for the bend pipe that erosion corrosion occurs, improves anti-corrosion capacity and reduces bend pipe resistance.
Background technique
In recent years, bend pipe on the pipeline of the process industrial devices such as oil refining, chemical industry, metallurgy, thermoelectricity and nuclear power lost efficacy and causes the phenomenon of equipment shut-down to happen occasionally because of erosion corrosion, even also caused serious accident, safety, the long-term operation of device have been restricted, and along with equipment is towards maximization, high parameterization development, the bend pipe resistance installing pipes obviously increases, and to industry energy conservation consumption reduction, has brought stern challenge.Along with the construction of nuclear power, transfering natural gas from the west to the east, the south water to north and oil long distance pipeline, the corrosion protection of fluid feed line and energy-conservationly become the build a conservation-minded society yoke of process of impact.
For energy-conservation, the design principle of pipeline is to reduce bend pipe as far as possible, and the member of these pipe fitting resistances of special reduction is not designed in the use of big or small first-class pipe fitting.But this design concept is not to reduce pipe resistance the best way.In order to reduce bend pipe erosion corrosion speed, traditional way is that the radius of curvature of bend pipe and the ratio of caliber are brought up to more than 3, although can effectively reduce erosion corrosion like this, taking up an area space increases, and has increased the construction cost of pipeline.Problem based on above, from the angle in flow field, designs a kind of bend pipe energy-saving anti-corrosive equilibrium flow field turbolator, has not only reduced pipeline erosion corrosion speed, and energy-conservation 10% left and right.
Summary of the invention
The problem that reduces erosion corrosion speed and reduction bend pipe resistance for bend pipe, the present invention is intended to change traditional method.Based on hydromechanical principle, a kind of energy-saving anti-corrosive equilibrium flow field turbolator is provided, be characterized in that compact structure, easy to install, long service life, energy-saving effect obviously, effectively reduce the feature of erosion corrosion speed.
The object of the invention is to be achieved through the following technical solutions:
A kind of energy-saving anti-corrosive equilibrium flow field turbolator, be arranged on bend pipe upstream, be used for improving anti-corrosion capacity and reduce bend pipe resistance, mainly by shell and setting guiding core body in the enclosure, formed, described guiding core body consists of some blades and central support, and blade is arranged in the space that central support and shell surround.
Described each blade one end is connected with central support and/or adjacent blades, and each blade the other end is connected with outer casing inner wall.
Described guiding core body and shell are welded to connect.
Described central support is located in the space that some blades surround, and the profile of central support and the curved surface of blade are tangent to coincide.
Described blade is welded on central support, and blade face of weld and intermediate support body section are tangent.
Described blade is the angle of attack and has the single current general character.
Described shell and guiding core body material are carbon steel or stainless steel.
Described leaf cross-section is streamline structure, and blade exists certain bend angle along the radial direction of shell.
Described central support adopts the streamlined structure of water droplet formula.
Energy-saving anti-corrosive equilibrium flow field turbolator of the present invention, by shell and guiding core body by being welded.Described guiding core body consists of one group of blade and central support with special construction, certain setting angle.Blade is welded on central support according to certain angle, and welded section and the central support of blade are tangent, and the large end of the front end of blade and central support welds together, and the afterbody of blade and the small end of central support weld together.Along the radial direction of shell, there is certain bending angle in blade.Make energy-saving anti-corrosive equilibrium flow field turbolator there is the characteristic of one-way flow.
As the present invention, further improve, described central support, is a solid support with streamlined structure, and its material is carbon steel or stainless steel.
As the present invention, further improve, described blade, its cross section adopts airflow design, two particular curves, consists of.And blade has certain bending angle along the radial direction of shell, its material is carbon steel or stainless steel.
Described shell is made by common seamless steel pipe.
The present invention is as the use of balance flow field, reduction resistance.During use, be arranged on the upstream of bend pipe.This device has single-phase mobile characteristic.During installation, according to the flow direction of fluid, select installation direction.When MEDIA FLOW is crossed this device, make fluid mean allocation on cross-section of pipeline, reduce fluid and remain in a standstill, thereby the resistance of reduction bend pipe reduces erosion corrosion speed.This kind of turbolator, its compact structure, easy to install.According to laboratory experiment research, show, this flow-disturbing can make bend pipe resistance 10% left and right that declines.
