Definitions
- Particle trap for separating particles from the flow of a fluid
- the invention relates to a particle trap for separating particles from the flow of a fluid, with at least one flow channel through which the fluid flows.
- the invention further relates to a method for separating particles from the flow of a fluid, and finally the invention also relates to the use of a particle trap.
- a particle trap of the type mentioned at the outset serves to separate solid particles which are contained in a flowing fluid from the flow. Such particle traps are of particular practical importance in the cleaning of diesel exhaust gases from vehicles.
- the particle trap must be regenerable by oxidation of the particles. It is placed in a tube such as B. be installed in the exhaust line of a motor vehicle.
- Particles in the exhaust gases of a motor vehicle often accumulate on the coating and / or on the outer wall, such as. B. in the exhaust line and / or on the outer wall such. B. in the exhaust line and / or in the catalytic converter of the motor vehicle. When changes in load, they are then in the form of a particle cloud, such as. B. ejected a soot cloud.
- Sieves which are sometimes also referred to as filters, are conventionally used to separate the particles.
- Sieves can basically collect the particles, but they have two major disadvantages: on the one hand they can clog, and on the other hand they cause an undesirable pressure drop. If no sieves are used, there is a risk that the honeycomb body of the catalytic converter will become blocked, ie the pores of the noble metals will be covered, and neither pollutants nor oxygen will be present on the particles diffuse covered areas to the precious metals. In addition, legal values for motor vehicle emissions must be observed that would be exceeded without particle reduction. There is therefore a need to create collecting elements for exhaust gas particles which avoid the disadvantages of the screens and filters and do not impair the effectiveness of the catalysts.
- the invention is therefore based on the object of creating a particle trap and a method of the type mentioned which separate particles from the flow of a fluid with the greatest possible effectiveness, the separated particles being able to be removed later by oxidation and the particle trap thus being regenerable.
- the wall of the flow channel has at least areas made of porous or highly porous material and that the flow channel has internals acting as a deflection or guide structure in such an arrangement that the particles are directed from the flow to the areas made of porous or highly porous material ,
- the solution to the object according to claim 11 is a method for separating particles from the flow of a fluid in a particle trap, in which the particles are trapped in at least one flow channel of the particle trap by at least one deflecting or guiding principle flowing fluid are thrown or directed against a porous or highly porous channel wall.
- the particles which are directed from the flow to the areas made of porous or highly porous material by the internals, adhere to the porous channel wall through interception and / or impaction.
- the pressure differences in the flow profile of the flowing fluid are of Importance.
- the deflections can create additional local vacuum and overpressure conditions, which lead to a filtration effect through the porous wall, because the pressure differences have to be compensated.
- the particle trap is in contrast to closed. Sieve or filter systems open because no flow dead ends are provided. In this case, these properties can also serve to characterize the particle trap, such as, for. B.
- Metal, plastic, ceramic, etc. are suitable as the material of the particle trap, with at least the part of the channel wall which is approximately opposite the internals being porous when the flow channels are formed.
- porous or highly porous sintered and / or fibrous material can be used as the porous material, whereby in addition to the deposition and adhesion behavior towards soot particles (e.g. large geometric surface, large inflow area, suitable depth of the structure), the shape stability, strength and corrosion resistance of the porous material or highly porous material play a role.
- soot particles e.g. large geometric surface, large inflow area, suitable depth of the structure
- the particle trap according to the invention and the method according to the invention are particularly important in their application to honeycomb bodies, as are known from the catalysts of motor vehicles.
- a porous channel wall is then realized, for example, by forming the entire honeycomb body from porous material.
- the permeability of the porous material is also of interest insofar as a radial flow through the particle trap can be achieved through completely porous channel walls.
- the channel wall is the channel wall in the entire length of the flow channel or part of the entire channel wall.
- the deflecting or guiding structure namely the internals, directs particles from the fluid at certain speeds against the porous wall, where they adhere.
- the separation of the particles is carried out according to the principle of "beater” and "catcher", the deflection structure as “beater” and the particles leading to the "catcher”, the porous channel wall or intermediate layer.
- the deflecting structures within a flow channel can be the same or different and the structuring of the flow channels within a particle trap J can also vary.
- the cross section of the flow channel is dimensioned so that even the smallest point in the channel allows particles of average size to pass through.
- the cross section is influenced by the deflecting or guiding structures and can be the same or different across the length of the flow channel.
- a preferred embodiment of the particle trap according to the invention is that the area made of porous or highly porous material is formed by an intermediate layer which is attached to the non-porous channel wall. In this way, there is greater freedom in the choice of materials.
- the practical implementation of the particle trap according to the invention is particularly advantageous if, according to a further development, the internals consist of at least one protrusion, bumps, knobs or the like, which is arranged opposite the area made of porous or highly porous material and may be axially offset from the channel wall. In this way, the built-in components can be produced easily and in optimal locations.
- the projections, bumps, knobs or the like can also be arranged in groups with an extension in regions in the circumferential direction of the channel wall.
- the effect can be achieved, for example, that within a particle trap, the particles that are deflected by the structures at a first flow velocity are first directed against the porous channel wall in successive partial areas, then the particles with a second, for example higher, flow velocity, which have not been deflected on the smaller deflection structures, etc.
- the particle trap in this case offers a possibility of separation for each flow velocity.
- the flow velocity and the flow pressure of the fluid flowing through the particle trap can be manipulated by the geometry of the deflecting and guiding structures and adapted to an optimized deposition rate.
- the increasing radial extension of the projections, bumps, knobs or the like into the interior of the flow channel means that not only the particles are deflected at a higher speed, but also those particles that are closely opposed to the porous channel wall; the diffusion path that a particle has to travel through the flow up to the wall area made of porous or highly porous material becomes smaller and smaller in this way.
- a particle trap has proven to be particularly advantageous, the internals acting as a deflecting or guiding structure in each case directing between 2% and 15%, in particular between 4% and 8%, of the particles still contained in the exhaust gas to the regions made of porous or highly porous material.
- Corresponding tests have shown that a particle trap designed in this way results in only a very small pressure drop, with a sufficient number of deflection or guide structures arranged one behind the other and / or offset from one another in the flow direction nevertheless ensuring very effective cleaning of particles. If necessary, it is also possible to connect several such particle traps in series, each with a few deflecting or guiding structures, which are optionally supported against one another.
- the number of deflecting or guiding structures should in particular be selected so that at least one statistical deflection of the entire gas flow takes place towards or through the porous material. It is currently known from tests that even the series connection of 10 to 15 such deflection structures in the flow direction leads to a separation efficiency of over 90% and even over 95% of the particles contained in the flow.
- the deflection of the particles still contained in the exhaust gas is preferably carried out by an appropriate configuration of the porosity of the porous or highly porous material and / or the size of the deflecting or lattice structure
- Particle trap causes. This means, for example, that less deflection of the stem opening with smaller deflection curvatures is required if the channel wall is sufficiently porous. In particular, areas with reduced pressures in adjacent flow paths are created near, in the flow direction behind, an un-steering structure, which consequently result in a suction of the particles into the porous material. With a corresponding adjustment of the particle trap to the majority
- the particle trap according to the invention be part of a honeycomb body with a large number of flow channels.
- the particle trap is particularly suitable for motor vehicle technology.
- a conical system or an element in the form of a cone is preferred.
- Such systems such as. B. described in WO 93/20339 have widening channels, so that at any mass throughput at any point of the channels, if they are provided with appropriate deflection or vortexing structures, particularly favorable conditions for collecting particles arise.
- the method according to the invention for separating particles from the flow of a fluid is advantageously perfected in that the porous or highly porous channel wall is regenerated continuously or discontinuously.
- Various aids can be activated in combination or individually. Aids are, on the one hand, upstream catalysts which provide sufficient NO 2 and / or upstream additions of additives which promote oxidation of the particles and thus regeneration of the particle trap.
- an NO 2 storage device can also be connected to the particle trap in terms of flow, for example a storage device made of perovskite, such as BaSnO 3 or another barium-tin perovskite, or an NO 2 storage device made of barium aluminate and / or one made of a barium zeolite.
- a storage device made of perovskite such as BaSnO 3 or another barium-tin perovskite
- an NO 2 storage device made of barium aluminate and / or one made of a barium zeolite.
- the method according to the invention is advantageously supported by aids which are released as a function of the degree of occupancy of the particle trap, this can be triggered in accordance with a pressure loss which is determined by the particle trap.
- the particle trap according to the invention is used particularly advantageously in the exhaust line of an internal combustion engine, in particular a diesel engine.
- the use in combination with a soot filter is particularly advantageous. In this case, the soot filter will of course be much smaller than with exhaust lines without a particle trap.
- Fig. 2 shows an embodiment of the particle trap according to the invention, in which the
- Area of porous or highly porous material is formed by an intermediate layer,
- FIG. 3 shows an embodiment with internals which progressively protrude further from the channel wall into the interior of the flow channel
- Fig. 4 shows an embodiment of the particle trap with one behind the other
- FIG 5 shows an embodiment of the particle trap which is supported in relation to a subsequent catalyst carrier body.
- Fig. 1 shows the flow channel 1, in which the fluid loaded with particles in
- Flow direction 8 (direction of arrow) flows.
- the channel wall 2 is completely porous in this case.
- the channel wall 4 is not at this point porous. At a low flow rate, the projections, bumps, knobs 3 or the like capture the particles of the fluid and deflect them onto the porous channel wall 2. They stick there. You can, for example, by regenerating the particle trap. Oxidation with oxygen at high temperature or by oxidation with nitrogen dioxide at lower temperatures can be removed.
- FIG. 2 also shows a flow channel 1, in which the fluid loaded with particles flows along the flow direction 8 (arrow).
- the channel wall 4 is not porous throughout.
- an intermediate layer 2a made of porous material is arranged.
- the projections, bumps, knobs 3 or the like are arranged opposite this intermediate layer 2a and slightly offset from it, so that here too the particles from the fluid are directed towards the porous intermediate layer 2a, where they remain adhered.
- Fig. 3 basically shows the same arrangement as Fig. 1; however, the projections, bumps, knobs 3a, 3b, 3c, 3d, 3e arranged one behind the other in the flow direction 8 are designed in such a way that their extension radially into the flow cross section becomes increasingly larger. In this way, the particles are deflected even at a higher speed, and there is an ever smaller distance from the warid area, which is porous or highly porous, so that the distances to the adhesive area for the particles also become smaller and smaller.
- the entire step of the flow channel 1 shown is made of porous or highly porous material, that is to say the projections, bumps, knobs 3 as well as the two channel walls 2.
- the radial extent of the projections, bumps, knobs and the like is in this case always the same. It is possible, but not essential, that the same porous material is used everywhere.
- 5 schematically shows an arrangement of an embodiment of the particle trap 5 in the exhaust line 6 of an internal combustion engine 7, the particle trap 5 here being supported directly against a catalyst carrier body 9 arranged downstream in the flow direction 8.
- the particle trap 5 is held with support pins 10 which are arranged in the flow channels 1 and preferably uniformly over the cross section of the catalyst carrier body 9 or the particle trap 5.
- Combustion engines 7 mean in addition to Otto engines, in particular engines of cars and / or motorcycles operated with diesel fuel.
- the support pins 10 are designed such that they have approximately the same cross section as the flow channels 1 and at least partially extend into them.
- the catalyst carrier body 9 can also be replaced by another component for cleaning the exhaust gas, such as a soot filter.
