Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, is only used for explaining the present invention, and is not considered as limiting the invention.
Below with reference to the accompanying drawings the flow mixer 10 of embodiment according to a first aspect of the present invention is described, the flow mixer 10
Have the advantages that simple in construction, easily fabricated, easy for installation, good mixing effect, fluid resistance are small.
As depicted in figs. 1 and 2, flow mixer 10 according to embodiments of the present invention, including tube body 100.
Specifically, tube body 100 can be corrosion-proof steel pipe, and hybrid channel 110 is limited in tube body 100, mixing
Passage 110 has import 111 and outlet 112, and the flow direction of fluid is the direction from import 111 to outlet 112.Hybrid channel
Be provided with multiple flow perturbation fans 120 in 110, each flow perturbation fan 120 by tube body 100 perisporium footpath of the part along tube body 100
Formed to inside bending, and each flow perturbation fan 120 leaves gap 130 on the perisporium of tube body 100.
In correlation technique, radial direction of flow velocity of the fluid under laminar flow condition along pipeline in pipeline is parabolically distributed, pipe
The flow velocity of fluid is 2 times of the mean flow rate of fluids within pipes at center in road, the annular region fluid of adjacent conduit internal perisporium
Flow velocity be significantly less than the mean flow raties of fluids within pipes, and the flow velocity of the fluid of adjacent conduit internal perisporium is close to zero.
Therefore, on the one hand, by the way that flow mixer 10 according to embodiments of the present invention is inserted in pipeline, in pipeline
Fluid enters hybrid channel 110 by import 111, and under the perturbation action of flow perturbation fan 120, the neighbouring internal perisporium of tube body 100 is (i.e. adjacent
Nearly pipeline internal perisporium) fluid be forced to take at the center of hybrid channel 110, and along pipeline axially towards outlet 112
Continue to flow, so as to improve the laminar flow conditions of fluids within pipes.
That is, flow mixer 10 can disturb the fluid in pipeline, make to flow through flow mixer 10
Fluid is changed into turbulent flow from stable laminar flow, fluid can in pipeline internal rotation, staggeredly, upset, and carry out interface renewal, in this way,
In flow process of the fluid in pipeline, carried out along with the circulation of the segmentation of fluid, displacement and mixing, in can making in pipeline
The fluid alternating of the annular region of fluid and adjacent conduit internal perisporium at the heart, transposition.
On the other hand, flow mixer 10 according to embodiments of the present invention, because flow perturbation fan 120 is directly by tube body 100
Perisporium cutting and inwardly bending form, so as to eliminate the welding in pipeline operation, manufacture, installation be easier, and save
Work material-saving；Because internal perisporium of the flow perturbation fan 120 not with pipeline welds, the service condition of flow mixer 10 is not influenceing pipeline just
Often use, also, flow mixer 10 is inserted directly into pipeline and used, this interpolation type structure for ease of maintenaince and is changed.
In addition, flow mixer 10 according to embodiments of the present invention, because the wall thickness of tube body 100 can be smaller, is flowing
The flow velocity measured under the same conditions relative to the spoiler fluid in correlation technique is very fast, and the power of fluid is stronger, mixed effect
Preferably.
In summary, flow mixer 10 according to embodiments of the present invention, can be in the bar for the conveying capacity for ensureing pipeline
Preferable mixed effect is realized under part, and it is simple in construction, easily fabricated, easy for installation.
According to some embodiments of the present invention, as depicted in figs. 1 and 2, each flow perturbation fan 120 is from import 111 to outlet
On 112 direction along tube body 100 radially-inwardly inclination extend, so as on the flow direction of fluid convection body carry out
The flow resistance of disturbance, good mixing effect and fluid is smaller.
In some embodiments of the invention, as depicted in figs. 1 and 2, multiple flow perturbation fans 120 are from import 111 to outlet
Along the circumference helically ladder distribution of tube body 100 on 112 direction, two neighboring flow perturbation fan 120 is respectively in tube body 100
It is arranged at intervals in circumference and on axial direction, so as to effectively reduce the resistance of fluid, effectively ensures the conveying capacity of pipeline.
Certainly, in some specific embodiments of the present invention, multiple flow perturbation fans 120 can also be along the axial direction of tube body 100
Be arranged in it is multiple rows of, often arrange being provided at circumferentially spaced along tube body 100 of flow perturbation fan 120.Wherein, in any transversal of tube body 100
In face, the flow perturbation fan 120 of suitable number can be set according to the interior diameter size of tube body 100, for example, when tube body 100
When interior diameter is smaller, the quantity of flow perturbation fan 120 is not more than 2；When the interior diameter of body 100 is larger, the quantity of flow perturbation fan 120 is big
In 2, so as to be advantageous to both ensure mixed effect, the flow resistance of fluid can be reduced again.
According to some embodiments of the present invention, each flow perturbation fan 120 is configured to rectangle or discount vibram outlet shape.For example, such as Fig. 1 and
Shown in Fig. 2, each flow perturbation fan 120 is configured to rectangle, and the overall diameter of tube body 100 is d, and the width of flow perturbation fan 120 hangs down
Directly meet in the central axis of tube body 100, the width W and length L of flow perturbation fan 120：(d/4)≤W≤(d/6), 1.5W≤L≤
2W, it thereby may be ensured that preferable mixed effect and preferable fluid delivery capability.
Advantageously, as shown in Fig. 2 the central axis of the length direction parallel to flow perturbation fan 120 of each flow perturbation fan 120 with
Angle α between the central axis of tube body 100 is 20 °~30 °, consequently facilitating being manufactured, structural strength is high and flow-disturbing is imitated
Fruit is good.
According to some embodiments of the present invention, as depicted in figs. 1 and 2, flow mixer 10 also includes the installation of annular
Ring 200, mounting ring 200 are welded with tube body 100, and mounting ring 200 is set around import 111, so as to facilitate flow mixer
10 are supported on pipeline, and the structure of flow mixer 10 is reliable.Wherein, mounting ring 200 can be corrosion resisting steel part, from
And service life is longer.
Advantageously, the interior diameter of mounting ring 200 is not less than the maximum gauge of import 111, and mounting ring is installed on tube method
Lan Shang, the overall diameter of mounting ring 200 are equal to the overall diameter of the sealing surface of pipe flange, so as to be advantageous to reduce the flowing resistance of fluid
Power, and convenient installation, good airproof performance.
The tube assembly 1 of embodiment according to a second aspect of the present invention, including pipeline 20 and implement according to a first aspect of the present invention
Flow mixer 10 described in example.
Specifically, tube body 100 is inserted in pipeline 20, and the internal perisporium of the periphery wall of tube body 100 and pipeline 20
Between coordinated using gap, the central axis of tube body 100 overlaps with the central axis of pipeline 20.For example, tube body 100 is outer
Gap between the internal perisporium of perisporium and pipeline 20 is smaller, i.e. and the overall diameter of tube body 100 is slightly less than the interior diameter of pipeline 20,
To reduce pumping pressure under conditions of mixed effect is ensured.
It is appreciated that tube assembly 1 also includes pipe joint 30, gasket seal 40, tube body 100 can be set at pipe joint 30
It is inserted into after in insertion gasket seal 40 in pipeline 20.For example, pipe joint 30 is bump joint, consequently facilitating installation and maintenance.
