Abstract
An atomizer for atomization of a first fluid within another fluid is of the kind where in a channel, which guides the second fluid, a wingshaped atomizer (1) means is comprised with an aperture (4) leading from one flat side of the wingshaped atomizer means tothe other flat side (11, 11A, 12, 12A) thereof, and where the wingshaped means comprises at least one through channel which from a side wall opening in the through aperture (4) extends to a supply channel or to a tube means for the supply of the first fluid to the atomizer, and where the wingshaped atomizer means at the through aperture (4), preferably at the side (9) which is orientated away therefrom from the direction of flow of the second fluid and preferably being present at both of the flat sides of the wingshaped means, has a smaller wing thickness (11A, 12A) of the wingshaped means and comprising a towards the through aperture orientated rounded off or sharpened wingshape-leading-edge-like edge (9). To achieve a better atomizing, also when only one supply side wall opening in the through aperture (4) is comprised, the through aperture (4) comprises a to the last mentioned edge (9) opposite and in any rate somewhat or mainly oblique positioned side wall (8) of the aperture (4). These (8, 9), connecting the lateral walls (6, 7), may have unequal lengths and may be oblique positioned, just as the outer contours of the wingshaped means (1) completely or partly or for portions thereof may be shaped in conformity with the side walls (8, 9, 6, 7) of the through aperture (4).
Description
Atomizer .
The present invention relates to an atomizer for atomization of a first fluid within another fluid of the kind where in a channel which guides the second fluid a wingshapedatomizermeans is comprisedwith an apertureleading from one flat side of the wingshaped atomizer means to the other flat side thereof and where the wingshaped means comprises at least one through channel"which""from a side wall opening inthe aforesaid through aperture extends..tσ a supply channel or to a tube means for the supply of the first fluid to the atomizer, and where the wingshaped atomizer means at the through aperture, preferably at the side which is orientated away therefrom from the direction of flow of the second fluid and preferably being present at both of the flat sides of the wingshaped means, has a smallerwing thickness of thewingshapedmeans,andwhereby the wingshaped means in it oriented towards the through .. aperture has an edge like a leading edge of wingshape type which, being orientated towards the through:.aperture-, may . be either rounded off or sharpened shaped.
It belongs to the state of the Art to position such an atomizer means within a channel having for instance square or circular cross section and which guides a fluid which for instance may be gaseous and to which fluid the first fluid has to be mixed as an atomized fluid when the first fluid ispresent as a liquidorvapourandthesecond fluid is a gas orvapour, and if the second fluid is a liquid then to attain a close mixture of the two fluids or toattain.a dis¬ perse of notably the first fluid into the other fluid. To this purpose the wingshaped means is thus posi¬ tioned within the second fluid that this fluid flows against a front leading edge of the transverselyto the flow positioned wingshaped means and therefrom passes along both sides of the wingshaped means having the wing-
shape orientated in parallel to the flow direction and leaves the wingshaped means at the trailing and thinner edge thereof which edge may have a sharpened shape running transversely to the direction of the flow. In general such a wingshaped means is stretched from side to side of the flow within the full cross sectional width of the channel and by means of pins is kept inppsitionr.at'the'S"e sidewalls, which pins may be tubeshaped and may be connected unto one, two or more channels in the wingshaped means and which channels lead to the through aperture in the wing shaped means and via- a sidewall opening or .via sidewall openings lead the first fluid out and into the through aperture, from which aperture the first fluid, particularly along the sides of the wingshaped means, .is spread into the second fluid.
It belongs to .the state of the Art to supply the first fluid via two opposing sidewall openings belonging to the through' aperture by supplying equal quantities of the first fluid simultaneously through the openings per unit of time, whereby the collision between the two supplied quantities of the first fluid contributes to the atomizing of the first fluid into the second fluid which is passing preferably along both of the side surfaces of the wingshaped means. By closing one of the side wall supply openings which open into the through aperture an atomization still takes place but not as effectively, and in cases of mix- turing the fluids or producing dispersion the efficiency is not as good as according to the aforesaid procedure. Of practical reasons it is not particularly easy to arrange two equal and from opposite directions each other meeting supply currents of the first fluid arriving with¬ in the through aperture in the wingshaped means, space- requiring supply tubes are thus required on both sides of channel for the first fluid. If thus, as it often is the
case, more such atomizing wingshaped means for one and the same fluid are arranged in one and the same channel, and where it is remarked that more first fluids, having each its set of atomizing wingshaped means for the second fluid, may be present, the number of supply tubes or hoses inclu¬ ding branching means of as well mechanical as current technical kind presents as well a problem as a drawback.
It is the purpose of the present invention to provide an embodiment of the wingshaped means by means of which an effective atomization is attained and whereby only one single side wall opening belonging to the through,.aiper- ■ ture leading through the wingshaped means from one flat side to the other is needed for the supply of the first fluid to the atomizer. It is remarked, that nothing pre- vents that fluid can be led simultaneously or alternati- . • vely to the through aperture without necessarily having to be supplied neither in equal manner nor oriented against each other in the through aperture,: as more than one side wall opening is used contrary to the solutions accor- ding to the invention, and these openingsdo not necessari¬ ly have to be opposingly arranged.
This purpose is attained by means of the characteri¬ stics described in claim 1. Hereby a better mixing of the two fluids is achieved. Generally it suits the purpose if the two mentioned sides of the through aperture.are run - in such a way that their spacing is larger the larger the distance is from the side wall opening through which the first fluid is supplied. For reasons of viscosity the spacing may decrease at augmenting size of distance to attain the best result.
By means of the characteristics described in claim 2 this may be further improved. Generally, it is an advan¬ tage if the lateral wall along the circumference of the through aperture has a shorter length than the two al- ready mentioned side walls of this aperture.
By means of the features according to claim 3 a further improvement is attained. The lateral wall with largest extent along the circumference of the through . aperture in general is the side wall which simultaneously does not comprise the side wall supply opening for the first fluid.
By means of the features according to claim 4 the atomizationmay be further improved.
Dependent on viscosity and adhesion unto the surface of the two fluids it may be advantageous'to attain improved atomizing or mixing to employ the features which are de¬ scribed in claim 5, as the improved fluid run-off at the single side surfaces of the wingshaped means then may be influenced to form small turbulent whirls or to provide flow hindrances or the opposite l-srecϊ within the vicinity of the side surfaces of the wingshaped means, as the oblique form together with the geometrical shape of the through aperture, when supplying the first fluid solely through one side wall opening belonging to the through aperture, may be furthermade.use of to obtain improvement of the achieved atomizing or mixing of the fluids, and to which purpose the features according to claim 6 are effec-r tive.
By using embodiments according to claim 7 and/or 8 an atomization may be achieved which is adaptable to possible, within a channel leading the second fluid, uneven flows of this fluid at one or the other side surface of the wingshaped means, whereby the features according to claim 7 are related to the symmetrical flow at the two side surfaces of the wingshaped means, whereas the fea¬ tures according to claim 8 somewhat are related to uneven flow conditions of the other fluid along the flat sides transversely to the flow of the second fluid.
In this respect further improvements of the atomi- zing or mixing are attainable by means of the features ac-
cording to claim 9 and/or 10 as a better adaptation to such uneven flow along the flat sides may be achieved transverselyto the flowof the second fluid, namely as partly the structural extent of the thrcaigh?. aperture but also partly the extent of the external contours of the wing¬ shaped means to a larger extent may be adapted to uneven flows within the total width of the channel leading the second fluid.
Embodiments according to the invention are described in more detail in the following with reference to the drawing, wherein:
Fig. 1 and 2 illustrate a embodiment of a wingsha¬ ped means according to the invention, fig. 3 and 4 show an alternative embodiment of a wingshaped means according to the inven¬ tion, and fig. 5 and 6 illustrate an embodiment of a wingshaped means to be used at unequal conditions of flow for the second fluid.especially. The figures 2, 4 and 6 respectively show the cross sections II-II, IV-IV and VI-VI according to the respec¬ tive figures 1, 3 and 5.

A wingshaped means for an atomizer according to the inventionαa^ £BS-"refg efiCe* *αMeara"l 1. The upper flat sur¬ face of the wingshaped means is referred towith 11 , respec¬ tively by 11A, whereas the lower flat surface is referred to with 12, respectively with 12A. 11A and 12A designate depressed surface areas within the wingshaped means and which areas in direction towards a; through aperture 4 run¬ ning from 11, 11A to side 12, 12A are tapering into a sharpened or rounded off edge 9 turned against the through aperture 4. At the back the wingshaped means 1 terminates
in an edge 19 whereas anteriorly the wingshaped means terminates in a curved or sharpened edge 18. Opposite to the sharpened or rounded off edge 9 of the aperture 4 an¬ teriorly the aperture 4 has a side wall 8. Lateral walls 6 and 7 connect as side walls the two side walls 9 and 8 of the aperture 4.
Internally in the wingshaped means 1 a channel 10 is running which opens into the lateral wall 6 of the aper¬ ture 4. At the other end the channel 10 through a stud 10A is connectable to a first fluid which through the side wall opening in the lateral wall 6 has to be supplied to the through aperture 4 to be mixed with a second fluid which flows around the wingshaped means 1.
The wingshaped means 1 can by means of the stud 10A and of a pin 5 positioned opposite to the stud 10A be held to the side walls of a in the drawing not shown fluid channel, in which channel the fluid flow, in case of an em¬ bodiment of the wingshaped means as shown in the drawing, is flowing around the wingshaped means r?in direction from left to right, i.e. in direction from edge 18 to edge 19. The first fluid flows out to both sides from the through aperture 4, and in case the second fluid is gaseous or is a vapor an atomization of the first fluid into the second fluid takes place. This is due to the striking of fluid against the edges of the aperture 4, but is also due to the formation of whirls within this range.
When, as shown in figures 3 and 4, the rear edge 19 is oblique, whereby the edge 19 and the edge 9 are conform, a better atomizing is attained. The side walls 11, 11A, 12 and 12A may comprise grooves or forrows mainlyrunning to the right hand side in the drawing or just raylike towards right in the drawing from the area around thethrough aper¬ ture 4. In many cases the atomizingherebybecomes improved. To achieve better atomizing a wingshaped means 1 with curved side walls of a through aperture being conform with theouter contour is illustratedΞUI figure 5. •"--."
