Description

Be used to the method and the whizzer that make air flow through whizzer
The present invention relates to a kind of be used for making whizzer treat with particle for example dust and/or moisture from surrounding air flow through the method for whizzer, be that equipment carries the air that purifies, described equipment for example be ventilation, heating, air regulator and/or be used for to machinery, motor etc. such also at the device of the equipment air feed of vehicle.The invention still further relates to a kind of whizzer of this method of application, its flat construction unit by a three-dimensional constitutes, and this construction unit comprises inlet, through-flow mouth and outlet and the integrated through-flow and resolution element that separates grid form, is used for air flowing.
Such whizzer is known with simple structure and effect by DD214297.
According to according to the SGW Werder Co., Ltd further feature of the inside prior art of exploitation of the disclosed description of product formerly, such whizzer is known as follows:
The construction unit of the three-dimensional of-one formation whizzer starts in described equipment or the vehicle so that install or pack into as prefabricated installing component;
-in the internal structure by air inflow of the inside of this whizzer in order to guide air to be provided with, each vertical pipeline by the different section bar of cross section constitutes, it is made of the separation level that is used for particle to be separated in being provided with of its mutual zone, wherein each section bar is arranged the width as same grid that occupies a whizzer side by side, and the different cross section of section bar is provided with the mutual piecewise of the cross section that is used for the through-flow sky of air about separating level in a degree of depth of whizzer; And
The cross section of-each section bar has molding structure concave and/or convexity on the surface that is flowed into by air.
Each section bar is along the height of structure and installation unit generally, extended observation towards flow direction, constitute empty, at first diminishing cross section, so that quicken the air enter and the cross section that changes gradually, so that deflection is flowed and speed is reduced to the cross section of the air that stops guiding in the zone of the separation level that is used for particle to be separated and last sky in order to discharge the air of purification.
The machinery above-mentioned according to this design moulding separates grid, and it has:
-a plurality of becoming a mandarin of extending and separate section bar of being parallel to each other, wherein the section bar of two adjacency constitutes a flow gap that is used for air flowing respectively;
-the first section bar plane, its conglobate basically section bar that becomes a mandarin by sealing constitutes, and connects the section bar plane that two other streamwises are positioned at its back, and it is by constituting to the unlimited over there conglobate basically separation section bar of flow direction;
-each separates the back that section bar is positioned at a mobile gap on the section bar plane that is positioned at its front.
DE 100 42 443 A1 are from the prior art and notice such problem, that is, because little rigidity produces vibration, the less service life that it causes little separating degree and after this separates grid in long special-shaped bar.Derive its task thus, that is, make it not produce such vibration problem above-mentioned separation grid formation.Reasonably press the scheme proposals of DE 100 42 443 A1, the section bar that separates that become a mandarin section bar and streamwise is positioned at the 3rd section bar plane of its back connects bridge with one and interconnects.
This scheme be it seems at first function, although it no longer is new-type.What but should not ignore is wherein at first keep the second section bar plane constant, thereby it not to be taked such measure and does not eliminate in this section bar plane pipeline at least or reduction vibration best.
Except that this problem, can completely specifiedly be, according to the whizzer of described prior art because the separation that centrifugal force is used for particle has effectively had improved greatly characteristic.But it is not also optimized about the parameter with on the function on the technical pattern fully, for example
-favourable manufacturing;
The structure of the mechanically stable of-special-shaped bar and noncritical vibration characteristics;
-little constructional depth;
-high separating degree;
-minimum the pressure loss;
-big as far as possible centrifugal force and Gravity Separation;
-comprise little intrinsic noise; And
-bigger inflow velocity scope.
Quote as above, about determining by the scheme of DE 100 42 443 A1, Krapf and LEX Nachf. traffic technique Co., Ltd and limited partnership before this, ventilation and filtering technique about vehicle, by the company's description of product before 30 days Augusts in 2000 open so-called " a plurality of nozzle air grid ", by it as can be known, the section bar that separates that section bar and streamwise be positioned at the 3rd section bar plane of back that becomes a mandarin connects bar with one and interconnects.
In rolling stock was made, relevant professional domain had been devoted to separate at the machinery of the cooling air suction that is used for motor vehicles function, setting, structural design and the flow region in transverse section of section material of grid especially.Described and disclose this problem thus and be included in complexity among " Glaser yearbook " (ZEV+DET Glas.Ann.118 (1991) No.11/12) about following aspect:
The action principle of-current so-called centrifugal force precipitate and separate device;
The effort of the computer aided optimum of the grille-like of-separator;
-for performance parameter, the pressure loss and the sound pressure level of measuring dust and fluid separation applications and the experiment of audio spectrum; And
-performance test, practical application and other prospect.
Can determine that now what reached improves result who not only relies on experience under the result who utilizes economic flow optimized but also the mensuration that relies on relevant parameters.But also there is further improved possibility.
Scheme for the requirement of considering to accord with raising in more detail, except that here desk evaluation, for the form of implementation of the whizzer of up to the present describing, can further develop under the situation of decisive parameter about element and section bar as separating the structure of grid considering to improve.
Set out thus in the research here, that is, utilize strong acceleration effect and the interception before a mobile dead band to turn to, the particle that exists in air flows is produced strong centrifugal force.In view of this, the above-mentioned known whizzer with the setting of described separation grid is can be improved.Like this, for reaching the little progress of this whizzer, still must stand complicated form of implementation about many different special-shaped bars.The advantage of thin portion is being got in touch the deterioration to relevant parameters on the tolerance of shortcoming and reservation and the function all the time.
In such analysis and research, find, in " Aerosol Science andTechnology ", I.R.Torczynski and D.J.Rader two people in the 26:6 of in June, 1997 version and people such as Chih-Chieh Chen, Sheng-Hsin Huang, Wen-Yinn Lin, Tung-Sheng Shin and Fu-Tien Jeng in the 31:6 of in December, 1999 version, the simple model that may constitute away from this professional domain that is used for aerosol has also been described the cyclone effect (simplification) that comprises laminar flow and turbulent situation.
Definite by experiment in the evaluation of this publication, the centrifugation of known so far same a kind of whizzer is mainly concerned with the acceleration (deceleration) in interception section bar or the above-mentioned separation section bar.
Thus, the objective of the invention is, in this whizzer, according to the through-flow vertical or horizontal acceleration of method forced air, make particle going along with such as dust and/or water in its different state of aggregation because its higher density and inertia no longer can be followed air.In this case-be different from so far-also will by transverse acceleration (centrifugal acceleration) and by minimum deflection radius, very big steering angle and when turning to high flow velocity strengthen centrifugation so that
-realize the in fact higher inflow velocity scope of generation, but stand the little pressure loss;
-further improve little water droplet and the separating degree of particle from surrounding air;
-avoid the hydrodynamic noise that causes by the section bar that becomes a mandarin and critical vibration; And
-wherein also realize the super flow velocity of whizzer by the travel speed that for example reaches about 350km/h, and influence does not separate.
For this purpose, with structurally design like this of whizzer, that is, can be not only separate in the unified special-shaped bar of grid but also separate in the different special-shaped bar of grid structure each become a mandarin section bar and they one one
-can flow into from front and side towards going into flow path direction;
-also utilize preposition thin plate to operate reliably with a plurality of holes or sieve aperture;
-with respect to vertical line+/-45 ° installation site can operate reliably; And
Even-bigger setting height(from bottom) can not have vibration problem yet, and as basic separating mechanism on function/structure in conjunction with one " virtual cyclone separator (virtuellenZyklon) ".
As a kind of scheme of the present invention, for separation grid with unified special-shaped bar, above-mentioned purpose according to be used for whizzer through-flow, comprise that the method by the method step of claim 1 to 22 reaches.
Mainly stipulate according to this: mobile wall by means of convex bending is compelled to carry out the direction variation of an extreme and these walls formations is faced the cavate capture zone that comprises the repetitive cycling district, specifically, is three distinctive flow regions that are positioned at a special-shaped bar.Whereby, structurally realize virtual whirlwind effect for unified special-shaped bar, find out the new flow process according to method, wherein the separation of the particle of dust form must be extra high, that is in fact reaches 100%.
Should emphasize that wherein principle of the present invention satisfies each actual condition aspect following, promptly
-method step and the method condition of utilizing claim 1 to determine separately, and
But-the measure that utilizes claim 2 to 22 of the present invention not only can single formation but also is utilized on its fullest ground generally.
In order to use this method, construct whizzer of the present invention according to the feature of claim 23 to 35.
Here also should emphasize, the section bar of the separation grid that the present invention determines can be realized by the architectural feature of claim 23, that is even do not constitute second and three-chamber capture zone S3, S6 yet, but utilize the design that is similar to Fig. 1 and 2 according to following claim, particularly claim 24 to 30 makes it perfect.
On this function of the special-shaped bar of unification of newly-designed whizzer and structure on and at first technical favourable possibility, flow by larger slot formula capture zone with the repetitive cycling by effect contact combination and can obtain a kind of especially in the unexpectedly high separative efficiency of solids, it did not also reach so far.
In addition, the big volume flow of liquid also can advantageously be separated and get rid of to the structural possibility of large scale capture zone, therefore obtains the advantage of constructing on the structure aspect application person, because can guarantee that higher through flow velocity is as core speed.
Purpose for proposing provides a kind of improved products greatly by means of unified special-shaped bar, and it is perfect and further developed the relevant pattern of the centrifugal force-virtual-cyclone separator that is used for a reality.
These advantages and improve and aspect the user, can help to improve serviceability, and needn't stand the pressure loss additional in through-flow and/or harmful vibration.
Also have technical advantages at last, that is, separating grid can also only be made of an independent extrudate, and this is conclusive and embodies special feature of the present invention for reducing cost and cost.
As second theme arranged side by side with first solution of the present invention, above-mentioned purpose is for the separation grid with different special-shaped bars, realizes according to the method by the method step of claim 36 to 51 that comprises that is used for whizzer.Provide the whizzer of this method of enforcement by feature according to claim 52 to 62.
For this scheme, the same following regulation of technical purpose, flowing is compelled to carry out the direction variation of an extreme by means of the wall of convex bending, and these walls are constituted each cavate capture zone that comprises the repetitive cycling district.This is made of three distinctive separated regions, and specifically, first and second separated regions are made of the second special-shaped bar and the 3rd separated region is made of the first special-shaped bar.Whereby, structurally realize virtual whirlwind effect for different special-shaped bars, can utilize the new flow process according to method, it is used for the separation of liquid particle is had the occasion of high request, because it reaches in fact 100% surprising separating degree, this was confirmed in experiment already.
Embodiment by two correspondence two invention schemes describes the present invention in more detail.In the accompanying drawings, Fig. 1 to 5 illustrates and comprises a mobility status and a whizzer that separates grid that is made of unified special-shaped bar, Fig. 6 illustrates the whizzer that comprises a separation grid that is made of two different special-shaped bars, and Fig. 7 illustrates the schematic diagram of the whizzer of two invention schemes.Wherein:
The perspective view of the special-shaped bar of the present invention that Fig. 1 extends at the height of its length upper edge whizzer constitutes the separation grid by it, and described whizzer comprises a separation grid that is made of unified special-shaped bar;
First scheme of Fig. 2 whizzer is by the signal partial graph by the cross section of each special-shaped bar that become a mandarin of Fig. 1, and comprises that the basic section bar of the present invention constitutes and flow region in the configuration of the principle of these special-shaped bars;
Fig. 3 press Fig. 1 that constitute with process each the special-shaped bar that is provided with similarly through-flow in according to the motion pattern of experiment;
Fig. 4 a) and b) in the process of pressing Fig. 3 is similarly through-flow according to the solids trajectory diagram of experiment;
Fig. 5 a) and b) in the process of pressing Fig. 3 is similarly through-flow according to the liquid particle trajectory diagram of experiment;
The signal partial graph in the cross section of the separation grid that the alternative plan of Fig. 6 whizzer constitutes by two different special-shaped bars, this separations grid comprises section bar formation and the separated region that the present invention is basic; And
The whizzer that Fig. 7 one schematically illustrates there is shown its front view, sectional view and vertical view.
Schematically illustrate a this principle structure with whizzer of a plurality of vertically extending special-shaped bars 1 by Fig. 7, it is held in the framework 2 and can connects as jockey 2.2 by means of for example tapping screw in this case and is fixed in the corresponding section bar structure 2.2.With the height of H mark whizzer, with its width of B mark and with the length of l mark abnormity bar 1.One degree of depth T is roughly taken by the width b (Fig. 1) of special-shaped bar.
A plurality of special-shaped bars 1 constitute described separation grid 3, and it flows into air by side Le along the direction of arrow, and wherein air is being cleaned later on by separating grid, and flows out at side La with along the direction of arrow, then it is defeated by the target that need supply gas.
Whizzer has a discharging area 6.In this zone, assemble solid and particle liquid that separates in the length of the special-shaped bar 1 in the textural edge of section bar with downward (arrow) shear flow owing to gravity with tackle, and do not remove via being shown in further detail there with unlabelled lines of orifices.
By such positive action, be in order to the section bar of mask work structure and from this zone, continue to get rid of among the particle that separates, and can freely be used for continuous separation again from leaked-in air.
As shown in fig. 1 and conspicuous by Fig. 2 to 5 equally, each special-shaped bar 1 can be made by an independent extrudate.Wherein the important section bar zone of its present invention or the structure of section bar also can be made of each special-shaped bar capable of being combined or can be arranged spaced apart, as it as shown in Fig. 6.
The air La that equally represents leaked-in air Le and outflow with arrow among Fig. 2 with and flow direction.
At first, as first scheme, the process of describing method of the present invention and the mode of action and to be incorporated into a whizzer in the grid 3 of separating with unified special-shaped bar on its function with on the structure.
Schematically illustrate the drawing in side sectional elevation of the separation grid 3 that constitutes by unified special-shaped bar 1.1 among Fig. 2.Marked region S0 to S9 represents flow region, below relates to them.Mark P0 to P5 sign is separated the relevant portion to functional description of section bar.The characteristics of separate particles describe in more detail by result and mensuration by experiment confirm in the section bar.
Each through-flow station of separation grid by special-shaped bar 1.1 is described with functional steps from air inflow side Le to air outflow side La.
Determine as follows with reference to Fig. 2 to main points of the present invention:
-from S0 in the inflow region of S1, make by flowing into the mobile about 4 extraordinarily fast of forming part P0, this in Fig. 3 with shown in the streamline symbol describe;
-from S1 in first flow region of S4, make almost 45 ° of main flow deflections;
-be used for first and second cavate capture zone S2 and the S3 of particle, flowing is blocked and average speed is nearly reduced to zero;
-main flow is defeated by from S4 to second flow region of S8 and turned to about 90 ° consumingly along a moulding tongue piece P2 then.The in fact virtual cyclone separator that the common formation of this zone and the capture zone under it is made every effort to according to purpose;
-from S5 to the three-chamber capture zone of S6, flowing is blocked once more, wherein forms the recirculation zone (see figure 3) of slow rotation at position S5, it is by driving from the main flow of S4 to second flow region of S8;
-in this three-chamber capture zone S6, constitute dead (water) district (Fig. 4) of a secondary circulation, and flowing velocity drops to almost nil value in four barrel capture zone S7;
-the diffuser that constitutes by the first and second molded surface P5.1 and P5.2 once more partly expansion flow and, from separation grid of the present invention, discharge again at S9 hollow air-flow as recovering from the pressure of S8 to the 3rd flow region of S9.
From Le to La through-flow, the minimum total losses of gross pressure is allocated as follows by the present invention:
-in fact do not losing from the acceleration of S0 to the inflow region of S1;
-the pressure loss only occurs in separation level S1-S4-S8 through-flow of corresponding first and second flow regions, and this is not a shortcoming with respect to prior art at least;
-between the S8 of the 3rd flow region and S9, recover a part of power pressure, wherein on the whole by the profile that can freely separate optimal design abnormity bar 1.1 and make the mobile pressure loss reduce to minimum whereby by diffuser.
100% solids separation nearly reaches like this according to form of implementation of the present invention, promptly, force mobile (as by Fig. 4 a) and 4b) obviously easily see) in alignment with longitudinally or horizontal acceleration, make since the higher density of particle going along with (thereby and bigger inertia) it can not follow mobile.Wherein illustrate with the flow graph explanation.
-Fig. 4 a) be under the condition of parameter d dust≤10 μ m and speed U=5m/s the solids track and
-Fig. 4 b) is solids track under the condition of parameter d dust 〉=30 μ m and U=5m/s.
According to purpose, high flow velocity is strengthened the centrifugation of transverse acceleration (centrifugal acceleration) by little deflection radius, big steering angle and when turning to.Compare with the previous prior art of describing, for example according to DE 100 42 443 A1, its centrifugation is mainly concerned with the vertical acceleration (deceleration) of interception in the section bar, according to the major part of the effect of method of the present invention and whizzer from transverse acceleration.
The separating mechanism of solids at length is constructed as follows:
-be accelerated jointly and improving its momentum with flowing from S0 particle in the inflow region of S1;
-because to flow into the surface (as the bearing-surface profile of front) of forming part P0 be crooked, by its centrifugal acceleration that causes with particle going along with in the edge region with its transverse to the tendency leads of main flow direction to the centre that flows into cross section S1;
-particle, it can not be followed flow direction and carry out about 45 ° variation between the S1 of first flow region and S4, be dumped among the first cavate capture zone S2, in this region S 2 based on very low flow velocity;
-in the first cavate capture zone S2, the momentum of particle is owing to the collision on wall and reflection are lowered (Fig. 4 a) and 4b)), and the second cavate capture zone S3 improves the number of wall collision and captures some particles (Fig. 4 a) and 4b));
-by being changed by the minor radius of moulding tongue piece P2 guiding and high almost 90 ° the strong direction of speed current downflow between the second flow region S4 and S8, particle is thrown toward S5 and gets rid of among the three-chamber capture zone S6.In addition, particle trajectory is guided on the fixing border that is flowing among the passage area S4 into.Particle is by recirculation zone S5, partly losing its momentum (Fig. 4 a) and 4b) under the assistance of the reflection on the forming surface P4 and by the collision of the wall in three-chamber capture zone S6).
-secondary repetitive cycling in three-chamber capture zone S6 flows and to help at first to keep there the particle that is captured for the particle diameter of appointment and particle density (Fig. 4 a);
-the four barrel capture zone S7 supports the centrifugation of particle, it enters in this chamber (Fig. 4 a) and 4b) by wall reflection), wherein has only small particle, it is enough little of light, so that can follow transverse acceleration, or it is not separated and discharge because wall reflection is thrown away from capture zone in S9 from separate grid.
Therefore will make as follows according to splendid separation function of the present invention zone:
-the curved surface that flows into forming part P0 and moulding tongue piece P2 produces the centrifugal acceleration in through-flow, and it causes the throwing away of particle going along with of the density more higher than liquid component;
-first, second, third and four barrel capture zone S2 and S3 and S6 and S7 be used as interception and separated region the most efficiently.
According to the separation of droplet of the present invention from flow advantageously basically with suitable to the description that solids carried out.Difference between the behavior of little water droplet and the behavior of solids only is that its particle encounter just occurs on a profile wall.Though reflect from wall after the collision of solids in one elasticity/plasticity, a little water droplet forms a skin covering of the surface after wall collision, and it flows out under the influence of wall shearing stress and gravity.But when bouncing, a water droplet also may form satellite droplet.The diameter of this satellite droplet may be so little in this case, so that it can follow the outlet of flowing up to separating grid, but its quantity is less.
Below enumerate according to Fig. 5 a) and 5b) process, the separating mechanism of its small water droplets is different from the separating mechanism of solids, on function, also be applicable to the second invention scheme that to describe below other especially for this effect that reaches actual 100% fluid separation applications here, that is according to Fig. 6, having the separation grid 3 that is made of two different special-shaped bars 1.2,1.3 can realize.
Below illustrate with flow graph:
-Fig. 5 a) be parameter d water 〉=10 μ m and and the condition of U=5m/s under the liquid particle track and
-Fig. 5 b) is liquid particle track under the condition of parameter d water≤10 μ m and U=5m/s;
-at first, particularly big water droplet has been run into the section bar surface and has been flowed out (Fig. 5 b) as skin covering of the surface in the zone that flows into forming part P0);
-on the first and second separation edge P3.1 and P3.2 this film break away from surface and liquid be discharged into first and three-chamber capture zone S2 and S6 in;
-whole little water droplet, it collides on the section bar surface in the first cavate capture zone S2, as liquid film because gravity flows out and therefore separated;
-particle, it is dumped among the three-chamber capture zone S6 along recirculation zone S5 by passage area S4, bumps against on the inwall of catch tank of such formation and separated there;
-first, second, third and four barrel capture zone S2 and S3 and S6 and S7 not only be used as the capture chamber of flight water droplet but also be used as the eliminating of surface liquid film;
-removing little water droplet, it is enough little or light, consequently follows and flows beyond outlet, also has only amount of liquid not separated (Fig. 5 is a)) seldom, it falls to diffuser P5.1, in the zone of P5.2.
As for the difference between the characteristics that relate to characteristics on through-flow, separating mechanism and the structure two invention schemes, of the present invention, should emphasize:
Realize by " virtual cyclone separator " by making every effort to according to purpose for-one basic separating mechanism.Therefore emphasize relevant therewith flow region, wherein force to flow by means of the wall of convex bending basically and carry out strong direction and change.Capture the chamber in the face of this wall is provided with, in this captures chamber, constitute the repetitive cycling zone, form and flow tranquil space and guarantee the effective separation of particle;
-to pass through at region S 2 and S3 and S5, S6 and S7 (Fig. 2 and 3), big catch tank among similar 5.1,5.2,5.3 (Fig. 6) and repetitive cycling thereof flow, and separative efficiency also is high for solids:
If must separate big liquid capacity flow, then the capture chamber determined of large scale also is favourable, and this guarantees higher through flow velocity as core speed on function, and provides on the structure and the advantage on making for the user;
Wherein, do not strengthen the through-flow pressure loss with respect to prior art.
Therefore pass through the method for the present invention and the structure of whizzer, in two kinds of schemes, for relevant application person or operator, in the finished product of favourable technology manufacturing, improve the efficient and the serviceability of centrifugal separator of the present invention greatly as centrifugal force-virtual-cyclone separator.
In this respect, technically in the first invention scheme particularly advantageously be, only 3 extrudates 1.1 being determined by unique a kind of number are formed, thereby this can reduce manufacturing expense and also reduces cost.Still should emphasize that the separation grid 3 with unified special-shaped bar 1.1 can be applicable to whole particles, the important optimal separation of preferred solids.
If but in the scope that requires, also to separate in fact 100% the liquid particle or the liquable particle of any state of aggregation, the second method scheme described below would then be adopted and according to the form of implementation of Fig. 6.
Prerequisite to this is that mobility status in each flow region that describes in detail among the embodiment in front and mobilization here also are like this.But because geometry different configuration or the distribution of each capture zone that is used for particle to be separated on two different special-shaped bars, here also will be by its mark and structural design each specific separated region of invention programme definition with respect to the front, and the flow region of lay special stress on same purpose no longer.
Through-flow method according to the whizzer of the second invention scheme, wherein have with different special-shaped bars 1.2,1.3 the grating type section bar that is provided with by the air inflow, make leaked-in air by means of the first special-shaped bar 1.2 become the forming part 1.2.1 that becomes a mandarin of convex bending at first to quicken to enter the cross section 4.1 of the diminishing sky of a nozzle-type to flow direction, wherein different special-shaped bars 1.2,1.3 is configured for particle to be separated equally mutually in it is provided with capture also is configured for the cross section that gradually changes 4 that air can flow through simultaneously with separated regions.
After this on the one hand air flows to the first section bar part 1.3.1 that the streamwise into the second special-shaped bar 1.3 opens wide, therein separating solid particles to a considerable extent in having first separated region 5.1 of the first resolution element 5.1.1.
Make the deflection of air stream on the other hand and continue to turn to and enter among the second section bar part 1.3.4 that the vane type of the second special-shaped bar 1.3 opens wide.Special here also unprecipitated moist particle is almost completely separated in having second separated region 5.2 of the second resolution element 5.2.1, because form dead (water) district (being similar to the description to the first invention scheme of Fig. 4) of a secondary circulation there by the special geometrical construction of second separated region 5.2, it guarantees actual 100% fluid separation applications prerequisite.
At last, make air stream turn to the 3rd section bar part 1.2.2 that opens wide of the first special-shaped bar 1.2 on the one hand, its formation has the 3rd separated region 5.3 of the 3rd resolution element 5.3.1, be used for the particularly separation completely of reality liquid or liquable particle, and on the other hand in the cross section 4.2 that enlarges gradually of the air stream of discharging, in second zone that connects between the outer wall of bar 1.3.3 and the 3rd section bar part 1.2.2 that opens wide, guarantee the pressure recovery.
At described separated region 5.1,5.2,5.3 middle flow velocity can drop to zero nearly, make and wherein partly form the tranquil dead band of flowing, thereby the particle that separates is constantly along special-shaped bar 1.2,1.3 length because downward shear flow and the gravity effect addressed in first embodiment are gathered in the discharging area 2.1, and can be excluded by the there.
According to method, (being similar to the first invention scheme) flowed to be intercepted at and is positioned at separated region 5.1,5.2, in the recirculation zone in 5.3 the zone and make its rotation lentamente therein.Flow therein and can carry out off-load by main flow driving and the diffusion effect that constitutes by means of the wall between the section bar surface of the first special-shaped bar 1.2 and the second special-shaped bar 1.3 then.In fact after this air do not have particle and flow to application places.
In this respect,, can tackle mobilely in the capture zone that 1.3.4 constitutes, wherein in these capture zones, can form (extremely) zone of the conclusive secondary circulation of function at the section bar part 1.3.1 that opens wide by at least one.
Generally, in fact air will be the no pressure loss from entering (Le) up to discharging the through-flow of (La) whizzer.
The pressure loss of main portions is limited to the wall of first cross section 4.1 that opens wide of the second special-shaped bar 1.3 and first flow region that connects between the bar 1.2.4 of the first special-shaped bar 1.2.
This method keeps recovering the power pressure of a part by means of diffusion effect.
