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 it can make sense for cost reasons, the water vapor Use as atomizing 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 mixing inside and outside mixing nozzles are in Nasr, Jule and Bendig, Industrial Sprays and Atomization, Springer-Verlag, 2002 , for example, on page 24.
  • a spray-drying nozzle in which a sputtering gas is split 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 is a two-fluid nozzle for atomizing pasty or solids-containing fluids, such as mud, described in which the fluid to be atomized through a central, cylindrical channel and fed at the end of this channel by annularly arranged individual nozzles, the sputtering gas is injected into the fluid to be atomized.
  • the invention is intended to improve an externally mixing multicomponent nozzle for the spraying of fluids.
  • 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. Furthermore, 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. Thus, by design, 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 should be noted that the sputtering quality in industrial practice occasionally to form deposits within the nozzle or at the nozzle 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 outlet nozzle be formed as a Laval nozzle, so that the hot atomizing gas then exits at supersonic velocity from the outlet opening.
  • FIG. 1 shows a multi-fluid 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 Zerstäubungsgasströmungen. 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 also has a very good part 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 discharge opening 60 is according to 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.
  • the problem of stalactite-like deposits does not occur here, as is to be observed in end surfaces of nozzles according to the prior art.

  • 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.
