Description
Technical field
The utility model belongs to gas structure for conveying technology, and in particular to a kind of gas flow guiding piece, available for sulphur-containing exhaust gas
Or the processing of other pernicious gases.
Background technology
Guiding device is in terms of gas treatment using very much；Convection current of the existing spiral grooved tube to body central regional fluid is difficult
To strengthen；Turbolator pipe makes it destroy the ability of fluid boundary layer due to there is certain gap between turbolator and inboard wall of tube body
Weaken, can increase the resistance drop of tracheae；Shaped telescopic tube manufacture is of high cost, and is only capable of having effect to the thinned of fluid boundary layer,
It is limited that effect is strengthened in convection current to body central regional gas stream.
The content of the invention
The invention discloses a kind of gas flow guiding piece, prepares simply, is especially integrally formed, and avoids existing flow deflector from existing
The problem of many places seam, the guiding device obtained with tube combinations can effectively guide pernicious gas such as sulfurous gas along water conservancy diversion
Piece is run, and especially by the design of structure, can effectively be guided while air-flow so that its oxide is formed and obtained effectively
Collect.
Utility model adopts the following technical scheme that：
A kind of gas flow guiding piece, including a plurality of gas flow guiding units；The gas flow guiding unit is helical structure；It is described
The central shaft of helical structure passes through the helicoid of the helical structure；The helical angle of the helical structure is 20~50 degree；It is described
Gas flow guiding unit one-sided smooth, the face opposite with shiny surface are equipped with plurality of grooves.
In above-mentioned technical proposal, the repeat number of the helical structure is 2, i.e., there are two for the helical structure of the utility model
Helicoid, forms gas flow guiding piece, overall gas flow deflector is also helical structure, and gas is in pipe by the helical structure of multiple repetitions
It is interior during by next helical structure, to form spiral flow again by forming spiral flow during a helical structure, thus air-flow from
The motional inertia of body makes it be always maintained at spin current；With solve the intensity of gas cyclone in the tube body present in existing diversion pipe compared with
The problem of weak, spin current continuation is poor.
In above-mentioned technical proposal, the side of the gas flow guiding piece is globoidal structure.Globoidal structure helps to assemble, and avoids
Contact surface damage is caused, and beneficial to barrier gas, also avoids injury of the structure such as square to operating personnel；The utility model gas
Composition air flow guiding device in body flow deflector insertion tube, and may be such that gas is run along flow deflector groove surface.
In above-mentioned technical proposal, the width of the gas flow guiding unit is the 5~15% of its length.Gas flow guiding unit group
Into gas flow guiding piece, it meets geometric definition, carried out by sheet be much larger than to possess certain thickness, width, length and length
The structure of width, the gas flow guiding piece of the utility model can regard a rectangular parallelepiped structure as if flat elimination helical structure is smoothed out with the fingers, limit
Aspect ratio is determined in addition to reflecting the structure of gas flow guiding unit, is more mainly ensured the intensity of gas flow guiding piece, is met industrialization
Up to tens of meters of application requirement.
In above-mentioned technical proposal, the depth of the groove is the 5~8% of gas flow guiding piece thickness；The width of the groove is
The 0.6~0.8% of gas flow guiding piece width；The length of the groove is consistent with gas flow guiding element length.The utility model it is recessed
Groove from gas flow guiding piece one end to the other end, contribute to gas flow and so that liquefaction oxide as groove flows down, limit ruler
The very little influence for avoiding uprising gas to down-flowing liquid, while avoid gas interface too small.
In above-mentioned technical proposal, the top of the groove side is globoidal structure, is conducive to gas flowing, avoids resistance,
Solve the problems, such as the resistance drop increase of tracheae.
The gas flow guiding piece of the utility model can be inserted into pipe, for example pipe is cylindrical structure, and one end is equipped with inverted round stage structure,
It so can not only stablize and fix gas flow guiding piece, but also can smoothly recycle sulfide；Preferably, a termination of inverted round stage structure
There is frustum cone structure pipe, inverted round stage texture edge is globoidal structure, and frustum cone structure side is globoidal structure.Frustum cone structure is top and bottom
The structure of round sides arc, the lower surface of the inverted round stage structure are overlapped with the upper surface of the frustum cone structure, pass through setting
Gas flow guiding piece can be effectively caught, it is especially simple in structure, prepare very convenient.
In above-mentioned technical proposal, the gas flow guiding piece is structure as a whole.Both ensure that it is easy to assembly, more mainly be beneficial to
Fluid consistency, and the design of integrated structure and size, possess very strong mechanical property, use stabilization；The utility model
Specific a shape and structure meet geometric definition in itself, if the globoidal structure on groove is the cambered surface of this area, its arc
Size is spent depending on gas flow guiding piece entirety.
In above-mentioned technical proposal, in the gas flow guiding piece, gas flow guiding unit is 2~20；The gas flow guiding piece
1.5~2.5 millimeters of thickness, the helical structure of the utility model restriction can be relatively easy to form, and combine size design, such as
In the case that this is thin, mechanical property is still preferable.
It is well known that to be only inorganic material such as quartzy for the material for sulphur-containing exhaust gas, and there are mechanics for such material
The essential defect of performance particularly compression strength difference, if structure size is unreasonable to cause its product especially helical structure system
Product can not obtain the product that length is grown, or even short product can not also use there are serious mechanical property defect；The utility model
First public gas flow guiding piece；The central shaft for designing helical structure passes through the helicoid of the helical structure, avoids existing
Spring structure is there are poor mechanical property, water conservancy diversion inertia is weak, almost can not liquid collecting the problem of, spiral shell is formed by the face of gas flow guiding piece
Radial facing, it is rational in infrastructure by the restriction of helical angle and other sizes, it can effectively handle exhaust gas, such as power plant's sulphur-containing exhaust gas warp
The utility model is crossed, sulfur recovery rate is more than 99.9%.
