Abstract
A static mixer is disclosed; at least two rows of steel pipe supports are disposed parallelly in a flue gas pipeline; two ends of the steel pipe supports are vertically fixed on any two parallel inner walls of the flue gas pipeline; the steel pipe supports are welded and fixed on the flue gas pipeline inner wall by liner plates; two adjacent rows of steel pipe supports are staggeredly arranged; arc spoilers are welded uniformly along the steel pipe supports with the arc surface orientation facing the fluid movement direction. The fluids impact the arc spoilers fixed in the pipeline, and cutting, shearing, rotation, and remixing of two or more fluids are generated; therefore the purposes of good distribution and complete mixing among the fluids are reached; and the static mixer is simple in structure, and high in efficiency.
Description
Technical field
The utility model belongs to gas denitrifying technology, particularly relates to a kind of static mixer.
Background technology
In glass stove gas denitrifying technology, after ammoniacal liquor directly sprayed in the flue gas, ammoniacal liquor was ammonia in gasification in a flash; Because the denitrating technique requirement, ammonia needs full and uniform mixing the, the traditional ammonia blender that in the coal-burning boiler denitration technology, adopts now with flue gas; Because it is simple in structure, gas channel is narrow, and fluid is simple in flue does laminar motion; Not only cause ammonia and flue gas to be not easy fully to mix, also can cause system's flue resistance to increase, cause behind newly-increased equipment for denitrifying flue gas; System needs the frequent change air-introduced machine, has strengthened production cost.
The utility model content
To the problem of the fluid undercompounding that has the blender existence now, the utility model aims to provide a kind of static mixer.
The utility model adopts following technical scheme: a kind of denitrating flue gas static mixer; In flue, be arranged with at least two row's steel pipe supports in parallel; Any two parallel inwall vertical fixing of said steel pipe support two ends and flue; Adjacent two row's steel pipe support interlaced arrangement, the steel pipe axis direction is evenly equipped with spoiler in said steel pipe support upper edge.
Between said steel pipe support and flue inwall, be provided with liner plate, said steel pipe support is welded on the said liner plate, and said liner plate is fixedly welded on the flue inwall.
Said spoiler is the arc spoiler, and its intrados welding is fixedly set on the said steel pipe support, and the extrados of said spoiler is relative with the fluid motion direction.
Fluid ejects from nozzle, and the arc spoiler in pipeline on impact flow first row's steel pipe support is under the effect of arc spoiler cambered surface; Fluid is diverted to the both sides of spoiler; Further impact on the second arc spoiler that be crisscross arranged of row, can increase the velocity gradient of fluid laminar motion like this and then form turbulent flow, the motion state of fluid is " cut apart-position is moved-converged again " during laminar flow; The motion process of fluid is long like this, undercompounding.And during turbulent flow, fluid also can produce violent eddy current in the section direction except that above-mentioned three kinds of motion conditions, have very strong shearing force to act on fluid, makes fluid quicken to cut apart mixing, and final mixed forms needed fluid-mixing.
The utility model is applicable to the static mixing between the multiple fluid; In pipeline, not having moving component, have only stationary element, is a kind of high-efficiency mixing device that does not have moving component; Through being fixed on the spoiler in the pipe; Make that two strands or a plurality of fluids produce cutting, shear, rotation and mixing again, thereby reach fine dispersion and well-mixed purpose between each fluid, be a kind of simple in structure, static mixer efficiently.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Embodiment:
Referring to Fig. 1, Fig. 2; In flue, be arranged with at least two row's steel pipe supports 1 in parallel; Any two parallel inwall vertical fixing of steel pipe support 1 two ends and flue in conjunction with referring to Fig. 3, are provided with liner plate 5 between steel pipe support 1 and flue inwall 3; Steel pipe support 1 is welded on the liner plate 5, and liner plate 5 is fixedly welded on flue inwall 3.Adjacent two row's steel pipe supports, 1 interlaced arrangement; Be evenly equipped with arc spoiler 2 at steel pipe support 1 upper edge steel pipe axis direction; In conjunction with referring to Fig. 4, the intrados of arc spoiler 2 is fixedly set on the steel pipe support 1 through welding, and its extrados is relative with the fluid motion direction.
Fig. 5 be static mixer at CFD flow field simulation sketch map, fluid ejects from nozzle 4, the arc spoiler 2 in pipeline on the impact flow first row steel pipe support 1; Under the effect of arc spoiler cambered surface, fluid is diverted to the both sides of spoiler 2, further impacts second and arranges on the arc spoiler that is crisscross arranged; Can increase the velocity gradient of fluid laminar motion like this and then form turbulent flow; Different fluid " cut apart-position is moved-is converged again ", and, have very strong shearing force to act on fluid at the violent eddy current of section direction generation; Make fluid quicken to cut apart mixing, final mixed forms needed fluid-mixing.
