Definitions
- the invention relates to an externally mixing Mehrstoffdüse for spraying fluids with the aid of a relative to the fluids to be sprayed hot atomizing gas, in particular steam or hot gas.
- the task is to mix a secondary fluid, in particular water, as homogeneously as possible in the primary fluid and often to evaporate by the shortest route.
- a secondary fluid in particular water
- two-fluid nozzles are often used.
- the liquid is atomized by means of a gaseous or vaporous auxiliary.
- These two-fluid nozzles are characterized by a particularly fine droplet spectrum and by a very good partial load behavior.
- water vapor is available. Then, for cost reasons, it may make sense to Use steam as a sputtering aid, because the provision of a corresponding amount of compressed air would be associated with high investment and operating costs.
- Two types of nozzles are available for atomizing with two-component nozzles, namely nozzles mixing on the inside and nozzles mixing on the outside. Examples of internally mixing and externally mixing nozzles are shown in Nasr, Jule and Bendig, Industrial Sprays and Atomization, Springer-Verlag, 2002, for example on page 24.
- US Pat. No. 3,770,207 discloses a spray-drying nozzle in which an atomizing gas is divided into two concentric annular gaps. Between the two annular gaps for the atomizing gas, an annular gap for the solution to be dried is arranged. The innermost annular gap for the atomizing gas is formed by inserting a cone piece into the central outlet opening.
- German patent application DE 195 26 404 A1 discloses a two-fluid nozzle for atomizing pasty or solids-containing fluids, such as mud, described in which the fluid to be atomized fed through a central, cylindrical channel and at the end of this channel by annularly arranged individual nozzles the atomizing gas the fluid to be atomized is injected.
- an externally mixing multicomponent nozzle for spraying fluids with the aid of a sputtering gas, in particular steam or hot gas, which has a housing, wherein the housing has an outlet opening for the sputtering gas, a first annular gap surrounding the outlet opening for fluid to be sprayed and a second annular gap for the atomizing gas surrounding the first annular gap and a distributor piece, the distributor piece having at least one flow channel for fluid to be sprayed from a connecting line to the first annular gap and at least one flow channel from a Zerstäubungsgasan gleichtechnisch to the outlet opening for atomizing gas ,
- the provision of such a distributor piece within the nozzle housing ensures that the fluid to be sprayed and atomizing gas are conducted over a short path to the first annular gap or the outlet opening and the second annular gap.
- Alone by the provision of the manifold and the consequent short distances only a small heat transfer is achieved by spraying fluid to the atomizing gas.
- the manifold is made of solid material and the flow channels are provided within the solid material.
- the housing has an annular channel for atomizing gas, which surrounds the distributor piece at least in sections.
- the sputtering gas from the annular channel can be guided in the second annular gap on a short path and, since advantageously the flow channel of the distributor piece for the sputtering gas emanating from the annular channel, the sputtering gas can be conducted over a short path to the outlet opening.
- the present invention proposes a novel nozzle concept in which the atomizing gas within a small distributor integrated into the nozzle housing is brought about a central atomization gas flow through the outlet opening as well as to an outer annular gap flow.
- the fluid to be atomized is also allocated to an annular gap which is arranged between the central flow and the outer annular gap flow of the atomizing gas.
- This distributor or the flow channels in the distributor are dimensioned such that it is passed by both the fluid to be atomized and the sputtering gas at a relatively high speed, so that there is hardly any time for the heat transfer.
- the surfaces leading to the heat transfer between atomizing gas and fluid are very small and the distances between the individual flow channels, which guide the cold fluid or the hot atomizing gas, are dimensioned as large as possible.
- the internal heat transfer from the hot atomizing gas, particularly water vapor, to the fluid being atomized is minimized or limited to an advantageous value.
- a certain preheating of the liquid can be quite advantageous, because hereby, in the interest of a good atomization, the surface tension and the toughness of the fluid to be atomized can be reduced.
- the invention is not exclusively concerned with the atomization quality, as can be determined in the laboratory under ideal boundary conditions on a virgin nozzle. Rather, it has to be taken into account that the atomization quality in industrial practice occasionally leads to the formation of deposits inside the nozzles or at the nozzles. Mouth suffers. This is especially true when hot water is used as the fluid to be atomized. Even if suspended solids are largely eliminated by filtration, deposit formation in the nozzle or at the nozzle mouth can often be detected by the precipitation of dissolved solids. This is especially true in those cases where a hot sputtering gas is used, which then causes the walls to heat up in contact with the service water. Limiting the heat transfer within the nozzle according to the invention can thereby also solve the problem of deposit formation in the nozzle.
- a thermal insulation is at least partially provided between the flow channel for fluid to be atomized in the manifold and the manifold.
- the flow channel for fluid to be atomized in the distributor piece is formed at least in sections by means of a tube inserted into the distributor piece.
- an air gap is provided at least in sections between the tube and the distributor piece.
- An air gap insulation leads to a further, significant reduction in the heat transfer from the cold to be sprayed fluid on the manifold.
- the connecting line for the fluid to be atomized is designed to be double-walled at least in the connection area to the distributor piece.
- a thermal insulation layer is provided between the first annular gap and the housing and between the first annular gap and the second annular gap.
- the outlet opening for the atomizing gas has the shape of a third annular gap.
- the fluid to be atomized is thereby absorbed between two annular gap flows of the hot atomizing gas, so that a very good atomizing effect is achieved.
- the third annular gap can be formed for example by inserting a cone piece in the outlet opening.
- the boundary of the first annular gap in the flow direction is arranged in front of an outer boundary of the second annular gap.
- the fluid to be atomized emerges from the first annular gap and comes into contact with the sputtering gas from the second annular gap, even before the sputtering gas has left the nozzle orifice at the end of the second annular gap.
- the atomizing gas from the second annular gap can not yet escape laterally so that the fluid to be atomized is accelerated by the flanking gas streams before it leaves the nozzle orifice. In this way, a finer atomization of the fluid to be sprayed can be achieved.
- the boundary of the first annular gap is arranged by one to ten times the width of the first annular gap in the flow direction before the outer boundary of the second annular gap.
- a section of the flow channel for the hot atomizing gas located immediately upstream of the outlet opening is formed in the housing in such a way that it initially tapers in the flow direction and, after passing through a constriction, widens again up to the outlet opening.
- an outlet nozzle for the atomizing gas can be formed convergent / divergent.
- this Tailored nozzle can be formed as a Laval nozzle, so that the hot atomizing gas then exits the outlet opening at supersonic speed.
- FIG. 1 shows an inventive external mixing multi-component nozzle in a sectional view according to a first preferred embodiment
- FIG. 2 is an enlarged detail of the multi-component nozzle of FIG. 1,
- FIG. 3 shows a multi-fluid nozzle according to the invention according to a second preferred embodiment
- FIG. 4 shows a detail of a multi-substance nozzle according to the invention according to a third embodiment.
- FIG. 1 shows a multi-component nozzle 1 according to the invention according to the invention.
- the task of preventing premature Entthalpielexice the sputtering gas by heat transfer to the liquid to be sputtered and to prevent the formation of deposits in the nozzle by temperature-dependent precipitation of dissolved at low temperature ingredients of the liquids solved in the following manner:
- the via the steam supply of the multi-component nozzle 1 supplied steam stream 10 is divided into two sub-streams in a novel, small-sized manifold piece 18, which can thus be integrated into the nozzle 1.
- An outer partial flow 30 and a central one are produced Partial stream 28 of steam or hot atomizing gas.
- the outer partial flow 30 is blown through an outer annular gap 29, while the central partial flow 28 via a central nozzle 62, which ends at an outlet opening 60, is blown out.
- an annular gap nozzle 20 for ejecting the fluid to be sprayed, especially to be atomized water is arranged.
- the approach of atomizing the liquid via a central stream and an outer annular gap stream of the atomization aid facilitates the atomization.
- Essential to the invention is the design of the manifold 18 for distributing fluid to be sprayed and hot atomizing gas to the individual outlet openings of the nozzle first
- a characteristic feature of the nozzle 1 is that the fluid to be atomized is not ejected via a central nozzle but via an annular gap.
- This annular gap can be made relatively large, because here a high exit velocity of the liquid is not required.
- the atomization is carried out according to the invention in that the liquid film is introduced between two high-speed Zerstäubungsgas- flows. As a result of the shear stress effect of these high-velocity flows, the liquid film is drawn out of the annular gap into a thin liquid lamella, which breaks up into small drops.
- the risk of material removal at the annular gap walls of the liquid nozzle, namely at the annular gap 21 greatly reduced and the long-term stability of the flow characteristics of such a nozzle is so far no problem.
- Such a nozzle but also has a very good partial load behavior, in contrast to Single-fluid nozzles according to the prior art with swirl generator in the liquid guide.
- the central nozzle 62 for hot atomizing gas with the outlet opening 60 is shown in FIG. 1 in the flow direction as a convergent-divergent Nozzle executed.
- this configuration operates as a Laval nozzle and the steam then exits the center nozzle 62 at the exit port 60 at supersonic velocity.
- the nozzle 1 has no end surface flushed with service water. This is achieved by the very narrow edges of the annular gap 21. Thus, the problem of stalactite-like deposits does not occur here, as can be observed with end faces of nozzles according to the prior art.
- Essential features of the nozzle 1 according to the invention relate to the thermal decoupling of the hot atomizing gas, especially steam, from the cold water at the nozzle connection and inside the nozzle.
- the supply line 4 for the water 5 is double-walled.
- Another interesting possibility is to use at least for the manifold 18 a material with low thermal conductivity, on the other hand for the predetermined operating temperature of e.g. 300 ° C is suitable.
- the predetermined operating temperature e.g. 300 ° C is suitable.
- Fig. 1 and Fig. 2 as an enlarged detail of Fig. 1 show the nozzle 1 in a sectional view.
- the nozzle 1 is intended to be disposed within a channel 3 carrying a primary fluid, such as flue gas, into which a fluid to be atomized is to be injected.
- the channel 3 is shown only schematically by one of its terminations. The nozzle 1 is thus within the flow of the primary fluid in the channel 3.
- the liquid to be atomized 5 is supplied via a connecting line 4 via a central port 17 of the nozzle housing 2 to the manifold 18 of the nozzle 1.
- the atomizing gas e.g. Superheated steam 10
- the atomizing gas is first fed via a pipe 1 1, which leads out like the connecting line 4 from the channel 3, an annulus 23 in the nozzle housing 2.
- a pipe 1 1 which leads out like the connecting line 4 from the channel 3, an annulus 23 in the nozzle housing 2.
- From this annular space 23 from the sputtering gas passes via at least one cutout 24 and at least one bore 25 in the manifold 18 in a central space 26 in the manifold 18.
- the bore 25 is dimensioned so that a defined division of the superheated steam 10 takes place in two partial streams, namely once via the bore 25 to the outlet opening 60 of the central nozzle 62 and once over the annular space of the annular nozzle 31 to the annular gap 29 at the nozzle mouth.
- the central nozzle piece 27 is screwed into the manifold 18 and forms the central nozzle 62 for the central steam jet 28.
- a flow path of the central nozzle 62 then passes to the central space 26 in the manifold 18 initially convergent in a first, conically tapered portion , This first conically tapering section is followed by a cylindrical section forming a constriction. This is then followed by a conically widening section to the outlet opening 60.
- the central nozzle 62 is initially convergent and then divergent and the cross-sectional dimensions of the central nozzle 62 are for dividing the vapor stream 10 onto the central nozzle 62 and onto the outer annular gap nozzle 31 with responsible.
- the outer vapor stream also called annular gap steam stream 30, is first fed via the cutout 24 to the annular space of the annular gap nozzle 31 and passes from here into the outer annular gap 29.
- the steam thus emerges both as a central steam jet 28 from the central nozzle 62, as well as from the outer annular gap 29th
- the outer annular gap 29 is formed between an outer hood 49 and the intermediate hood 34. From the outer annular gap 29 and out of the outlet opening 60, the steam exits at high speed up to high supersonic speeds, as illustrated in FIG. 2 by arrows 32, 33. Due to the interaction between the annular liquid jet emerging from the first annular gap 21, and the flanking steam jets according to the arrows 32 and 33, a droplet spray with the boundary 22, as shown in dashed lines in Fig. 1 is formed.
- the connecting line 4 is formed double-walled for the fluid 5, in which an inner tube 37 is provided until it is connected to the manifold 18.
- the connecting line 4 is thus double-walled and provided with a thermally insulating air gap 44.
- the connecting lead can also be made with a graphite bush to achieve thermal insulation.
- the flow channel in the at least one bore 19 in the manifold 18 for the supply of water to the annular space of the annular nozzle 20 is double-walled with the inner tube 38, wherein, as explained, between the inner tube 38 and the bore 19 in the manifold 18, an air gap lies.
- the water-conducting annular space of the annular gap nozzle 20 is thermally insulated from the central nozzle 27 as well as the intermediate hood 34 by layers 35, 36 of suitable material. These insulating layers 35, 36 may for example consist of metal with poor thermal conductivity or of ceramic material.
- a disk 40 made of a heat-insulating material is provided on a bottom surface 39 of the manifold 18, on which the connecting line 4 for fluid 5 is placed.
- the disc 40 is provided with through-holes to guide fluid 5 into the at least one bore 19 and the inner tube 38 in the manifold 18, respectively.
- the nozzle housing 2 is designed in several parts and has a first, approximately pot-shaped component 64 with the connecting line 1 1 for superheated steam and the connection 17 for the connecting line 4 for fluid 5.
- the manifold 18 is inserted, which is screwed onto the likewise inserted into the component 64 connecting line 4 and is supported in the radial direction via webs 66 on the inner wall of the cup-shaped member 64. Between the webs 66, the recesses 24 are provided, via the superheated steam 10 in the Flow channel formed by the bore 25 in the manifold 18 and to the outer annular gap 31 passes.
- the outer hood 49 is screwed.
- the intermediate hood 34 is arranged, which is screwed onto the distributor piece 18.
- the outer annular gap nozzle 31 is thus formed for hot atomizing gas, which ends at the nozzle orifice at the outer annular gap 29.
- the central nozzle piece 27 is screwed into the distributor piece 18. Between the central nozzle piece 27 and the intermediate hood 34, the annular gap nozzle 20 is formed for fluid to be atomized, which ends at the nozzle mouth at the annular gap 21. As already described, an annular gap nozzle 20 on one side bounding outside of the central nozzle piece 27 is partially covered with an insulating layer 35. Only immediately upstream of the annular gap 21 no insulating layer 35 is more provided in order to form the annular gap 21 can narrow.
- the nozzle 1 according to the invention can be seen to have a very compact design and, in particular, the hot steam 10 is divided into the central nozzle 62 and the outer annular nozzle 31 within the housing 2 of the nozzle 1 over a short path.
- the flow channel for superheated steam in the manifold 18, formed by the bore 25, passes through the hot steam to the central nozzle 62 is at an angle to the also provided in the manifold 18 flow channel for fluid to be atomized 5, formed by the bore 19 and the inner tube 38, respectively.
- the flow channel for superheated steam and the flow channel for fluid are thus arranged crosswise within the distributor piece 18. In the illustrated embodiment, an angle of about 45 ° between the central longitudinal axes of the flow channel for superheated steam and the flow channel for fluid.
- the manifold 18 is made of high-alloy stainless steel, which has a low thermal conductivity. In comparison with conventional brass nozzles, this already achieves a heat transfer from the superheated steam 10 to the cold fluid 5 which is reduced by a factor of about 8.
- the inner tube 38 which is inserted into the bore 19 of the manifold 18, forms a flow channel for the fluid 5 through the manifold 18.
- the inner tube 38 is designed as a rotating part and rests only in the areas 68, 70 on the inner wall of the bore 19 , Outside the regions 68, 70 illustrated in FIG. 1 in black, an insulating air gap 72 is located between the inner tube 38 and the distributor piece 18.
- FIG. 2 shows the nozzle mouth with the outlet opening 60 of the nozzle 1 in an enlarged view. It can be seen that the outlet opening 60 of the central nozzle 62, the end of the annular gap 21 of the annular gap nozzle 20 and the annular gap 29 defining the outlet of the annular gap nozzle 31 are located exactly at the same height transversely to the flow direction. Only outside of the nozzle 1 does this result in a mixing of the superheated steam jets from the annular nozzle 31 and the central nozzle 62 with the annular gap flow of fluid to be atomized from the annular nozzle 20.
- the representation of FIG. 3 shows a further multi-substance nozzle 80 according to the invention according to a second preferred embodiment.
- the multi-material nozzle 80 is constructed in many parts identical to the multi-component nozzle 1 in FIG. 1, so that only the features different from the nozzle 1 in FIG. 1 are explained.
- a central body 41 is screwed, which extends through a central nozzle 82 for superheated steam through.
- the central body 41 is thus completely flowed around by the central chamber 26 in the manifold 18 to hot steam.
- the outlet opening 60 of the central body is designed in the form of a widening cone 42, so that the outlet opening 60 is annular and an inner annular gap 43 for the exit of the bore 25 supplied portion of the superheated steam 10 is formed.
- the annular stream of fluid 5 to be atomized is thus trapped between two equally hot vapor streams.
- the central steam also flows out via the annular gap 43.
- the central cone 42 only flows around hot steam, which is largely solids-free, so that there is no relevant deposit formation risk on the cone 42.
- the steam consumption of the nozzle 80 with respect to the nozzle 1 can still be lowered slightly without this having a negative effect on the atomization quality.
- the central nozzle 82 can be designed as a Laval nozzle. In the illustration of FIG. 3, however, this is not the case.
- FIG. 4 shows sections of a multi-substance nozzle 90 according to the invention in accordance with a third preferred embodiment.
- the nozzle 90 is formed in many parts identical to the nozzle 1 in Fig. 1, so that only the deviating from the nozzle 1 features are described.
- the nozzle 90 has an outer hood 92, which is extended relative to the outer hood 49 of the nozzle 1.
- the outlet opening 60 of the central nozzle 62 and the annular gap 21 of the annular gap nozzle 20 for the fluid to be atomized are set back relative to the nozzle mouth.
- the nozzle mouth is formed in this case by the downstream end of the outer hood 92.
- contact between the annular liquid flow from the annular gap 21 and the hot gas flows from the outlet opening 60 and the annular gap 29 occurs even within the nozzle housing.
- the width of the annular gap 21 for the liquid is about 1 mm and this annular gap is compared to the nozzle mouth by about 5mm, so the fivefold width of the annular gap 21, reset.
- the invention thus provides an externally mixing multi-substance nozzle in which a minimal internal heat transfer between the fluid to be sprayed and the atomizing gas is realized.
- the division of the liquid to be atomized and the atomizing gas is carried out in a manifold which is integrated in the nozzle body or the nozzle housing.
