Definitions

• 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..t ⁇ 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
• 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.
• 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.
• 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.

• 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.
• 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.
• a channel 10 is running which opens into the lateral wall 6 of the aper ⁇ ture 4.
• 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.
• 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.
