Definitions

  • the invention relates to a device for introducing an additive into an exhaust gas or gas stream, which can be introduced into a gas duct, in particular into an exhaust gas line from a diesel engine.
  • the device has at least one nozzle and at least one mixer.
  • the additive may be a reducing agent or a compound that releases such an agent.
  • a device of this type is known, for example, from Published, Non-Prosecuted German Patent Application DE 36 42 612 A.
  • the device introduces a reducing agent into a NOx-containing exhaust-gas duct with intensive mixing.
  • the device is intended to achieve a homogeneous mixing of the reducing agent and the exhaust gas over a relatively short section of duct.
  • the nitrogen oxides are usually catalytically reduced.
  • a reducing agent in the exhaust gas from an energy conversion installation, for example, in a diesel engine. It has proven expedient to admix a reducing agent of this type or an additive that releases it as a reducing-agent carrier, in particular ammonia or urea (dissolved in water), to the exhaust gas only after it has emerged from the energy conversion installation.
  • a device for introducing an additive into an exhaust gas The exhaust gas is introduced into an exhaust gas line from a diesel engine and has a flow direction.
  • the device contains at least one nozzle, and at least one mixer for mixing the exhaust gas with the additive.
  • the mixer and the nozzle combined with one another form a structural and functional unit.
  • the mixer has a tubular body disposed approximately parallel in terms of the flow direction of the exhaust gas and houses the nozzle.
  • the tubular body has an upstream end with a first opening formed therein and a downstream end with a second opening formed therein and communicates with the first opening.
  • the mixer has lamellae supported by the tubular body, and the lamellae, with regard to the flow direction of the exhaust gas, face upstream at the upstream end of the tubular body and face downstream at the downstream end of the tubular body.
  • the mixer and the nozzle for atomizing the additive or the reducing agent itself are combined to form a structural and functional unit.
  • the combination can be introduced into the gas duct, i.e. can be fitted into the duct when the structural unit is operating as intended.
  • the mixer has a tubular body which is open at both ends, is parallel in terms of flow, is advantageously, in the installed state, coaxial with respect to the gas duct and at one end bears lamellae which face upstream and at the other end bears lamellae which face downstream.
  • the tubular body, in a gas duct that is circular in cross section is likewise circular in cross section.
  • the diameter of the gas duct into which the structural unit containing the mixer and the nozzle can be fitted should expediently be no less than approximately 200 mm and no greater than approximately 1000 mm.
  • the tubular body has diameter approximately 0.5 to 0.2 times the diameter of the gas duct.
  • the length of the tubular body approximately corresponds to 0.2 to 0.5 times the diameter of the gas duct.
  • the tubular body is expediently supported by a tubular connection piece that projects into the gas duct transversely with respect to the gas stream and through which a tube, which serves as a feed line and as a support for the nozzle or the injection device, extends as far as the center axis of the tubular body.
  • the nozzle is advantageously disposed in the region of the center axis of the tubular body, and therefore, in the installed state, of the center axis which is common to the gas duct and the tubular body.
  • the nozzle or the injection device atomizes the additive, for example ammonia as the reducing agent or urea solution as the additive, in the direction of flow of the gas stream.
  • a spray cone that emerges from the nozzle includes an angle of 20° to 60°, preferably an angle of 30°, at its cone tip.
  • Lamellae that are supported at the ends of the tubular body preferably form an angle of from 30° to 60°, in particular an angle of 45°, with the axis of the tubular body.
  • the lamellae are oriented in such a manner that, in the installed state of the device, they are supported on the inner side of walls of the gas duct by their free ends. In this case, the lamellae are approximately twice as wide at their free ends as at their root ends that are connected to the tubular body. Free spaces between adjacent lamellae are in this case approximately as wide as the lamellae themselves.
  • the lamellae which face upstream are staggered with respect to the lamellae which face downstream, so that every partial stream of the gas stream is made turbulent, in each case an identical number of the lamellae which face downstream and the lamellae which face upstream are provided.
  • the tubular body expediently bears in each case four to eight lamellae at both end sides, the lamellae preferably are formed of planar metal sheets.
  • FIG. 1 is a diagrammatic, partially, longitudinal sectional-view of a flue-gas cleaning device with a combined mixing and injection device according to the invention
  • FIG. 2 is a partially sectional plan view of the cleaning device
  • FIG. 3 is a front-elevational view of the cleaning device
  • FIG. 4 is a sectional view of the cleaning device taken along the line IV-IV shown in FIG. 1;
  • FIG. 5 is a sectional view of the cleaning device taken along the line V-V shown in FIG. 1.
  • FIG. 5 there is shown a gas or exhaust-gas duct 1 with a diameter d 1 of, for example, 200 mm to 1000 mm is connected, by a flange 2 (FIG. 1) to a preferably non-illustrated stationary diesel engine.
  • An exhaust gas A flows through it in the direction indicated by an arrow 3 .
  • a tubular connection piece 4 penetrates through a wall of the exhaust-gas duct 1 and projects into the exhaust-gas duct 1 transversely with respect to the direction of flow 3 of the exhaust-gas A and therefore at right angles to a duct axis 5 . If the duct cross section is circular, as in the exemplary embodiment, therefore, the tubular connection piece 4 runs in a radial direction. Outside the exhaust-gas duct 1 , the tubular connection piece 4 bears a flange 6 at its free end, on which an end plate 7 rests in a sealed manner, thus closing off an interior of the tubular connection piece 4 with respect to the outside.
  • That end of the tubular connection piece 4 which lies in the exhaust-gas duct 1 bears a tubular body 8 which is open at both end sides and is disposed coaxially with respect to the exhaust-gas duct 1 .
  • the duct axis 5 therefore forms the center axis of both the exhaust-gas duct 1 and the tubular body 8 .
  • the tubular body 8 has a diameter d 2 (FIG. 5) that corresponds to 0.2 to 0.5 times the diameter d 1 of the exhaust-gas duct 1 .
  • the tubular body 8 has a length that is approximately equal to 0.2 to 0.5 times the diameter d 1 of the exhaust-gas duct 1 .
  • first lamellae 9 which face upstream with respect to the direction of flow 3 of the exhaust gas A, are secured to an inflow-side end of the tubular body 8 .
  • second lamellae 10 which correspondingly extend downstream, are secured to an outflow-side end of the tubular body 4 .
  • the lamellae 9 and the lamellae 10 are disposed staggered with respect to one another, i.e. each of the lamellae 9 lies between in each case two lamellae 10 , and vice versa, as seen in the direction of the duct axis 5 . This can be seen relatively clearly from FIGS. 3 to 5 .
  • the free ends 9 a, 10 a of the lamellae 9 and 10 are approximately twice as wide as their root ends 9 b and 10 b, respectively, which are secured to the tubular body 8 .
  • four to eight lamellae 9 , 10 are secured to each end of the tubular body 8 , the lamellae 9 , 10 contain planar metal sheets. Consequently, they cause particularly powerful turbulence in the flowing exhaust gas A.
  • the tubular connection piece 4 contains a tube 11 that is supported by the end plate 6 and on which, at a free end side in the tubular body 8 , a nozzle 12 is held.
  • the tube 11 is connected via a line, in a manner which is not illustrated in more detail, to a reservoir for an additive which releases a reducing agent or for a reducing-agent carrier R, for example for an aqueous urea solution, and expediently, in addition, to an air connection for cooling and atomizing the urea solution which is, for example, aqueous.
  • a non-illustrated pump forces the reducing-agent carrier R, e.g. the aqueous urea solution, or a corresponding reducing agent, e.g. ammonia, through the tube 11 and through the nozzle 12 .
  • the nozzle 12 and the tubular body 8 with the lamellae 9 and 10 therefore form a structural and functional unit, the tubular body 8 and the lamellae 9 , 10 attached thereto representing, in functional terms, a static mixer or a mixing stage.
  • the nozzle 12 in this case lies on the common center axis of the exhaust-gas duct 1 and of the mixer 8 , 9 , 10 , which corresponds to the duct axis 5 .
  • the hot exhaust gas A from the diesel engine flows through the exhaust-gas duct 1 in the direction of flow 3 .
  • a small proportion of the exhaust gas A, and therefore at least one exhaust-gas partial stream flows through the tubular body 8 .
  • the reducing-agent carrier R is sprayed or injected through the nozzle 12 into the flowing exhaust gas A.
