Detailed description of the invention
Below in conjunction with accompanying drawing illustrated embodiment, the invention will be further described.
Inner concentric tube double helix static mixer, by interior left-handed blade, interior dextrorotation blade, outer left-handed blade, outer dextrorotation blade, location round bar, location annulus and body are formed.The interior twisted blade that rotation direction is identical is uniformly distributed along location round bar outer wall circumferencial direction, forms an inside spin element; The outer twisted blade that rotation direction is identical is uniformly distributed along inboard wall of tube body circumferencial direction, forms an external spiral element.Inner or outer screw element is along blender axis direction head and the tail continuous arrangement, and axially adjacent inner or outer screw element rotation direction is contrary, the certain angle and circumference staggers.
In or beyond blender, no matter its identical length is same each other or each other for screw element, and the inlet end face of the internal and external screw element of correspondence or exit end face are positioned on same cross section, such structure is conducive to ensureing that the time of staying of all fluids in blender is identical, eliminate axial backmixing, improve mixed effect.Inside and outside hybrid element length depends on the requirement of operation operating mode for incorporation time and system pressure, when helical blade torsion angle is constant, helical element lengths reduction can improve circumference and the radial velocity of fluid, the mixed of unit pipe range can improve, but unit pipe range pressure drop also can increase, owing to influencing each other between the two, there is an Appropriate for certain operation operating mode in hybrid element length, and hybrid element length gets 1 ~ 3 times of blender interior diameter usually.
The blade rotation direction of the internal and external screw element that blender is corresponding is contrary, twisted center is mixing tube axis, such arrangement can make the fluid entering blender in arbitrary cross section, form the contrary form concentric spirals stream of two rotation directions, and two spiral flows produce transmission and the exchange of radial material and energy under the effect of corresponding centrifugal force.Under the laminar condition that Reynolds number is less, although the radial centrifugal force of spiral flow is very little, but this power can make the fluid particles in internal and external screw stream form complicated chaotic flow, because chaotic flow has the characteristic of ergodicity, each fluid to be mixed will be mixed with each other evenly, the reason of Here it is this blender has under laminar condition good mixed effect.
Helical blade end face in each interior (outward) screw element of blender is concordant, the all structural parameters comprising rotation direction are identical, and helical blade all the other structural parameters (comprising length of blade, width, thickness, torsion angle etc.) except rotation direction of adjacent interior (outward) screw element are identical.Such structure is convenient to the processing and manufacturing of blender, reduces equipment cost, and what is more important can make blender inner fluid obtain uniform in axial, radial and circumference, improves mixed effect.
The helical blade quantity of blender in each in (outward) screw element is identical, and the helical blade quantity of the interior and external spiral element of correspondence can identical also can be different.The quantity of hybrid element internal helical blades determines the dividing degree for entering mixed cell fluid, and the degree of helical blade more multi-fluid segmentation is higher, and under low reynolds number, the effect of distributed rendering is more obvious, but the form drag of fluid also can be larger simultaneously.Generally, the quantity of hybrid element internal helical blades should in 2 ~ 5 scopes.
The helical blade torsion angle of the interior and external spiral element that blender is corresponding can identical also can be different.The torsion angle of helical blade determines the degreeof tortuosity of fluid under blade effect, and the radial direction of the larger fluid of torsion angle and circumferential flow velocity also can be larger, but flow resistance also can be larger simultaneously.For different fluids and treating capacity, there is an optimum value in the blade twist angle obtaining good mixed effect, and the scope of this value is generally 90 ° ~ 270 °.
The external diameter of blender inside spin element is identical with the internal diameter of external spiral element, is generally 0.4 ~ 0.6 times of blender interior diameter, and its Specific Principles determined to ensure that inward eddy is similar to identical with the flow of contour stealth.Can ensure that internal and external screw stream carries out sufficient material and energy transferring in radial direction like this, be convenient to internal and external screw element simultaneously and link together, be conducive to the fixing of whole blender internals.
Mixer shafts to stagger at interface place certain angle to (outward) screw element in adjacent, ensure that the fluid in last mixed cell runner is divided into two by the helical blade of next mixed cell, so just achieve the segmentation of different fluid micelle, merging process, this process is often all repeated once through a mixed cell, thus achieves the homogenizing of fluid.The offset angular of front and back screw element is the half of circumferential adjoining spiral leaf angle, namely
β i =
α i / 2,
β o =
α o / 2.
Each helical blade of blender inside spin element is fixedly welded on location round bar outer wall, and each helical blade of external spiral element is weldingly fixed on the inner side of location annulus, and each external spiral element has three location annulus, lays respectively at two end faces and intermediate cross-section.All inside spin elements are welded into an entirety by location round bar, and all external spiral elements are by also connecting into an entirety to the welding of former and later two location annulus of interface.After whole inside spin element is inserted into external spiral element, adjustment internal and external screw elements relative circumference orientation, carries out spot welding at internal and external screw blade contact point place and fixes.
