Definitions
- the present invention relates to a device for cleaning filter bodies, in particular particle filters, and to a method for cleaning filter bodies, in particular particle filters.
- Particulate filters are to be understood as meaning filters which are replaced by a filter
- filter body is to be understood as meaning any type of filter which carries out the filtering of solids or particles in order to purify or reduce the number of fluid flows, exhaust gas streams or the like from these substances or particles.
- the particles ejected from internal combustion engines include aerosols such as soot particles, metal oxides from the combustion of lubricating oil, and other insoluble organic or non-organic substances such as soot, unburned fuel, burnt oil components, and other soluble organics and sulfur oxides.
- aerosols such as soot particles, metal oxides from the combustion of lubricating oil, and other insoluble organic or non-organic substances such as soot, unburned fuel, burnt oil components, and other soluble organics and sulfur oxides.
- a so-called particle filter is provided, which is arranged in the exhaust gas region, for example of a motor vehicle.
- the exhaust pressure increases continuously as the particulate filter becomes increasingly particulate.
- the corresponding back pressure to the engine increases, resulting in a deterioration of fuel consumption and a poorer operating condition and increased engine wear. Therefore, it is necessary that the particulate filter, which stores the particles within the filter, is cleaned regularly, in particular at the latest when a corresponding maximum allowable back pressure is exceeded.
- An insufficient filter cleaning can be very costly and a
- the particles mainly remain suspended on the surface of the filter wall or remain in the interior of the filter by means of depth filtration
- Filter wall Larger particles can not pass through the filter wall and thus accumulate on their surface. That way, you can get fat Forming particle deposition layers on the filter channel surface.
- the physically effective mechanism for adhering the particles to the porous filter wall relies on adhesion.
- the movement of the particles to the filter wall is mainly due to the mechanism of diffusion and is superimposed by the flow of the exhaust gas through the filter.
- the filter walls themselves may consist of different porous materials, which are usually composed of fibers or powder.
- the porous walls may be arranged in the filter in different ways. In the case of fibers and metal powders, flat filter walls are more likely to be constructed, which are arranged in tubes, pockets or bellows.
- filters made of ceramic powder the so-called “wall-flow filter monoliths"
- a filter channel structure is used, the filter channels being mutually closed (with respect to the respective end), thereby forcing the exhaust gas flow through the porous wall structure
- Production process can produce different geometries or properties of the filter material.
- filter monoliths with a filter channel structure are distinguished by the following two types of particle deposition: on the one hand, a so-called wall deposit, which covers the entire surface
- Filter channel wall from the filter channel beginning to the filter channel end is formed and consists of a more evenly distributed deposition layer of particles.
- This deposit layer consists of a lower layer of non-oxidizable ash particles, which can not be reduced by a filter regeneration, and an upper soot layer, which is regenerated during the
- Filter operation can be reduced.
- This layer can be discharged easily and with less effort from the filter when cleaning the filter - for example, by compressed air surges. This is due to the fact that this deposit layer rests uniformly thin and so over the entire length of the filter channel is uniformly thick, so that when cleaning the filter with compressed air, the compressed air from the adjacent filter channel through the porous
- This ash plug is very compact in terms of its structure due to the permanent application of the exhaust gas pulsation and thus significantly harder than the deposit layer on the filter channel wall described above. Consequently, this ash plug can be discharged from the filter only with great effort.
- a development of the prior art provides that a device is provided which receives the preferably rotationally symmetrical filter and rotatably supports about its longitudinal axes. With a linear movement, which crosses the longitudinal axis respectively, is over the top and bottom face of the
- Filter body each have a nozzle device, preferably evenly moved back and forth.
- the nozzle device is provided in the formation of compressed air nozzles or a hose, which thereby over a small distance over the
- End face of the filter body is forcibly guided or partially uncontrolled on the surface of the end face is ground long.
- the compressed air that escapes from the nozzle is usually continuous.
- a particular disadvantage is that the rotation of the filter body and its
- Compressed air column can be constructed, since the compressed air escapes in the region of the ground on the one hand, but also on the nozzle side facing - outside the filter channel - the compressed air can escape.
- Filter body is additionally damaged by this cleaning process.
- Another disadvantage is that the thermal process takes a long time. It can be expected with time expenditure of up to ten hours. Thereafter, another cleaning process must be completed. For heavily soiled filter bodies, the cleaning process may need to be repeated several times to achieve an acceptable cleaning result.
- the object of the invention is to provide a device and a method with which a more efficient cleaning effect of filter bodies with filter channel structure, in particular particle filters, is made possible.
- the device and the method are particularly suitable for "wall-flow
- the monolithic filter body has correspondingly open and closed filter channels at its two end faces
- the advantage of this technical embodiment of the cleaning device is in the inflow unit.
- this inflow is first placed on the filter outlet side. Characterized in that compressed air is not only entered into a filter channel by the inflow, but also in the adjacent and the more adjacent filter channels, a much better cleaning result can be achieved.
- the immediately adjacent filter channels are each closed, whereas their adjacent filter channels are open again. This results in the more adjacent filter channels a pressure column, so that there can hardly or no air flow over the walls of the filter channels from the adjacent filter channels out there.
- the invention is characterized in that an apparatus and a method is provided, with which not only the rather easy-to-clean deposit layer of particles on the filter channel walls, but in particular the hard ash plug, which in the rear area or in the bottom of the
- Form filter channels can be triggered from the particulate filter.
- the apparatus and methods known in the art are very limited
- the device proposed here or the method differs in that an outflow device is formed which forms no distance between it and the front side of the particulate filter and thus the generated compressed air can be introduced directly into the filter channels pointing to the outflow device. There is almost no laterally escaping compressed air flow.
- the provided compressed air is introduced in a targeted manner into a plurality of mutually adjacent filter channels and in such a way that a pressure column is formed within the filter channels open to the outflow device. This will also be the
- Ash stopper at the channel ends (bottom) of the adjacent filter channels achieved.
- the outflow device is preferably circular and covers a number of closed and open filter channels. Alternatives can also be angular
- the further basic idea of the invention is the filter body
- the compressed air in the form of rapid compressed air bursts in the millisecond range is passed as a sudden pressure wave with a high pulse through the particle filter.
- This Compressed air shock has a much higher kinetic energy than a uniform air flow, which is known from the prior art.
- the pulsed compressed air is preferably carried out with a discharge device, which is designed such that the compressed air jet can be efficiently introduced directly into some filter channels of the particulate filter. It is preferably provided that between the end faces of the filter body and the discharge only a small or no distance is present, so that it is avoided that compressed air escapes outside the discharge. Due to the fact that optionally also pulsed air over the
- Outflow device is output, formed in the centrally located filter channels due to the air columns in the more adjacent filter channels also an air column. This in turn has the advantage that deposits are loosened in the adjacent filter channels, so that at the latest at
- the outflow device is preferably raised after a defined holding time on the respective central filter channels and implemented to the next touchdown point.
- the compressed air is switched off so that cleaning can be carried out very efficiently and cost-effectively.
- the outflow device is advantageously designed such that it has a diameter greater than a filter channel to be cleaned.
- a filter channel to be cleaned Preferably, at least fifteen to thirty (inflow) filter channels are covered in the diameter, wherein the outer edge of the outflow device provides a sealing means, so that no compressed air can escape.
- the outflow device thus starts on the end face of the filter channels to be cleaned.
- the distance of the attachment points depends on the effective diameter of the respective outflow device and can be adjusted as needed.
- Embodiment is provided that the filter body is rotated about its transverse axis by 1 80 degrees, so that can be sequentially cleaned from both sides sequentially.
- the outflow device is movable with a corresponding automatic kinematics, for example a one, two or three way system at any position of the end face of the respective filter body.
- a corresponding automatic kinematics for example a one, two or three way system at any position of the end face of the respective filter body. The system also leaves the
- the outflow device can be guided by a manipulator known from the prior art.
- the movements can be previously - preferably depending on the design of the particulate filter and the associated size - programmed so that an independent cleaning in the design of a machine can be done.
- a further alternative embodiment provides that the cleaning at the same time or with a time delay, both on the one end face and on the
- the controller responsible for the handling of each
- Outflow devices is provided, is preferably controlled individually. As already described above, the cleaning takes place for example by means of pulsed compressed air. A special design provides that this
- Compressed air pulse in turn, first in one in a corresponding time interval subdivided pulse phase, then followed by a pressure holding phase also with a defined time interval. Due to the position of the outflow device via the respective filter channels, a defined number of compressed air pulses can thus be introduced into the filter body almost loss-free.
- the direct placement of the outflow device on the filter body also causes the pressure profile with respect to the filter body or the respective filter channels can be monitored. So-called real-time monitoring shows the corresponding pressure curve.
- Cleaning device integrated device serves, on the one hand the
- Loading level with particles of the respective filter body in the delivery state that is, before the start of cleaning, as a so-called initial inspection to determine and detect whether the filter has been overloaded or not.
- the detection is done by detecting the pressure difference from the input to the filter channel and the recoil.
- the measurement of the corresponding cleaning performance and the degree of purity of the filter body then takes place during and after the cleaning and for the intermediate and final inspection.
- Regenerations resulting local overheating can also be determined by the corresponding pressure differences. Due to the real-time monitoring, it is also possible to create an overall picture of the filter body. After appropriate cleaning steps can then still be decided either automatically or by hand, whether certain areas that are overloaded and where the corresponding
- a further diagnostic device is provided. It can be integrated in the cleaning system as a module. It serves to control the catalytic coating of the corresponding filters. For this purpose, it is provided via the outflow device to enter a test gas with a concentration of nitrogen monoxide (NO) or carbon monoxide (CO) or hydrocarbons (HC) or optionally exhaust gas of an internal combustion engine and to measure on the opposite side then with a sensor, to what extent and in what quantity Nitrogen dioxide (NO 2) or carbon dioxide (CO 2) or hydrocarbons (HC) emerges.
- Vehicles or internal combustion engines approved according to the Euro VI emission class must comply with a number-related limit value for their emission of nanoparticles (ultrafine particles).
- a check of the filter with regard to its deposition rate for nanoparticles (ultrafine particles) after carrying out the cleaning is therefore expedient. Therefore, a further diagnostic device for controlling the particulate filter is provided with regard to its deposition rate for nanoparticles (ultrafine particles). For this purpose, it is provided to enter a test gas with a concentration of nanoparticles (ultrafine particles) or optionally exhaust gas of an internal combustion engine via the outflow device and on the
- Filter body provided.
- the appropriate test fluids with a dedicated sensor are used to produce a diagnosis.
- Tent depth measurement with a probe or with corresponding electromagnetic waves also provides information about the quality of the cleaned filter body.
- a further embodiment provides that the respective filter body is identified on the basis of the serial number or another unique identifier, so that the system can automatically adjust itself to the possible process paths and also the corresponding grid sizes of the respective filter channels on the end faces of the filter bodies. Only in this way is a targeted approach to the respective filter channels possible.
- a preferred embodiment provides that the data of the respective filter body, such as dimensions, grid size, operating hours, loading reason, etc., are stored on a database, so on the one hand via the appropriate means of communication (W-LAN, LAN connection, GSM or similar connections) respective cleaning devices and on the other hand, the cleaning results obtained and store the necessary data centrally. It is also intended to create a database for each already used filter body, so centrally the life cycle of such
- Filter body documented and the cleaning catch can also be displayed accordingly.
- the device is capable of the hard ash plug, which forms in the rear region of the filter channel, from the filter
- Contingencies or probabilities, or at least a single sweep or inevitable multiple sweep, as known in the art, are thus excluded.
- the benefit lies in a defined cleaning of the filter body over the entire filter body surface and in the fact that an efficient use of the machine time and the energy (also the compressed air) is given.
- each filter body can be cleaned with a minimum cleaning time required and minimal effort required in terms of energy use. It eliminates any external measurement effort to determine the quality of cleaning and data collection for the cleaning protocol or the respective quality assurance system provided.
- an additional pre or post-cleaning such as a thermal cleaning by
- the system and method described enables filter cleaning during regular vehicle and machine maintenance in the workshop.
- Filter body instead of the achievement of equal maintenance intervals, the filter life can be further increased and the filter can recover almost the full power even after a cleaning process.
- Another operating cost advantage is the fact that significantly less compressed air is needed.

- Fig. 2 A-B is a schematic representation of the method of action of
- Fig. 3 is a schematic representation of the method of action of
- a filter body F is shown.
- the filter body F has a honeycomb-shaped structure, such that the individual filter channels 2 are formed in the longitudinal direction L of the filter body F.
- the filter channels 2 are arranged in parallel.
- the mutually adjacent filter channels 2 have permeable walls 3 (FIG. 1C), at least for parts of the particles, so that the flow of, for example, arrow directions 4 shown in the figures is effected.
- the filter body F shown in the figures is a ceramic filter, namely a "wall-flow filter monolith.” It is characterized in that on the filter inlet side E (the side on which the exhaust gas flow into the filter body F inlet) are provided with filter channels 2, which are open to this side and are closed on the filter outlet side A and vice versa.Thus, the exhaust gas flow is forced to first enter the provided on the filter inlet side E filter channels 2 and then through the permeable walls 3 to diffuse until the exhaust gas flow through the adjacent filter channels 2 to the filter outlet side A exits.
- the particle deposition takes place on the inner surfaces of the filter channels 2, so that over time the individual filter channels K become clogged with particles.
- Fig. 2A is schematically a simple device for cleaning
- Filter bodies F (as shown in Fig. 1) shown in the embodiments of the prior art.
- This filter body has a filter outlet side A and a filter inlet side E.
- the filter channels that are open to the filter inlet side E are filled with particles P.
- the assignment takes place at the walls 3 and at the respective base 1 1, where in particular plug-like particle deposits S form.
- the device consists of a housing not shown in detail as well as a housing arranged within the cleaning device 5, which is shown schematically in Fig. 2A.
- the device has a holding device which is suitable for receiving and fixing the filter body F in a defined position.
- the cleaning device 5 has a manipulator with one or more degrees of freedom (arrows 6 in FIG. 2A).
- an outflow device 7 is arranged at its free end. This is supplied via devices not shown with air.
- the outflow device 7 is a nozzle, which introduces a uniform air flow in the filter channels 2 on the filter outlet side A of. In this case, the nozzle is arranged at a distance 8 to the end face of the filter outlet side A of the filter body F.
- Fig. 2B shows the difference with the prior art and thus the invention.
- This provides an outflow device 7, which covers a plurality of filter channels 2 open to the filter outlet side A, so that no distance is provided between the outflow device 7 and the front side of the filter body F.
- a cover unit 1 2 is provided, which is arranged in the region of the distance 8 and forms an at least almost a closed space between the outflow device 7 and the end face of the filter body F.
- the compressed air emitted by the outflow device flows in the direction of arrow 9 directly into the openings of the filter channels 2.
- the cover unit (1 2) is to be understood as an optional device, provided that the distance (8) between outflow unit (7) and the filter outlet side A or the filter inlet side E is too large.
- the discharge unit (7) shown is part of a cleaning device. This comprises a housing in which the filter body F to be cleaned can be arranged or fixed. Extraction devices ensure that the blown particles from the filter body F are disposed of properly.
- the compressed air provided by the outflow device 7 is at least partially provided with a pulse or is designed as a pressure surge, then the compressed air also diffuses in the region in which the plug-like
- Particle deposits S are present, so that they can be loosened and dissolved.
- the outflow device 7 shown in FIG. 2B only adjusts
- the outflow device 7 is preferably formed flat and parallel to the end face of the filter body F can be arranged. It has one or more outlet openings, from which air, in particular compressed air is output, which then in the corresponding
- Filter channels 2 of the filter body F passes.
- Fig. 3 is a plan view of a filter body F to be cleaned is shown schematically. A detail shows the checkered structure of the respective filter channels K. The filter channels 2 open to the image side are shown in white. The sealed filter channels 2 are shown dark. This view corresponds to the end face of the filter body F on the filter outlet side A. This means that when this end face is exposed to air, only air through the openings (shown in white) can penetrate into the filter body F.
- the corresponding arrows 9 indicate the respective air flows which correspond to those in FIG. 2A.
- the discharge device 7 is shown schematically as an annular element, wherein the arrows 9 arranged within the discharge device 7 show the path of the compressed air within the filter body F (diffusion through the walls 3 the filter channels 2). For this purpose, it is advantageously provided that the
- Outflow device 7 has a plurality of outlet openings for the exit of the compressed air. These are preferably arranged side by side in parallel (comparable to a shower head). A further education provides, which the individual
- Outlet openings are nozzle-like and adjustable in terms of their discharge direction.
- a single outlet opening is provided, whose diameter corresponds almost to that of the outflow device 7, so that with the outlet opening a plurality of end-side end filter channels with air
- the compressed air is preferably discharged in a pulse-like manner from the outflow device 7 and flows in the entire size of the diameter of the
- the cover unit 1 2 is to be understood as a kind of rubber-like skirt which surrounds the outflow unit 7 and comes into contact with the end face of the filter body F. This results between the or the outlet openings of the outflow unit and the end face of the filter body F almost
- the outflow device is therefore according to the invention substantially larger than a filter channel to be cleaned and thus has a diameter which comprises a plurality of end filter channels ending in the end.
- a plurality of end-side ending filter channels are covered, in particular those on each side
- the covering unit 1 2 described above can be provided.
- four filter channels 2 are considered below, which are identified in FIG. 3 by the letters U, X, Y and Z. These are filter channels 2, which are acted upon by the compressed air, but behave differently due to their position within the discharge 7.
- the filter channels 2 marked with X are located such that they are open to the filter outlet side A. Through this, the compressed air flows during the cleaning process and forms the pressure column.
- the filter channels 2 marked with U are located such that they are open to the filter inlet side E. They are acted upon by two sides (little), since in the two adjacent filter channels 2 each have a pressure column is constructed. Due to the low impact is a small
- the filter channels 2 marked with Y are located such that they are open to the filter inlet side E. They are acted upon from four sides, since in the four adjacent filter channels 2 each have a pressure column is constructed.
- the filter channels 2 marked Z are located such that they are open to the filter inlet side E. They are acted upon from three sides, since in the three adjacent filter channels 2 each have a pressure column is constructed.
- the air jet is pulsed accordingly, it has been found that the cleaning efficiency increases.
- the compressed air is output in a pulse-like manner, then it can preferably also be provided that it outputs many times and fast compressed-air surges. This results within the respective filter channel. 2 to the bottom of an air column, which causes the further pulsed compressed air no longer up to the bottom G, but much further within the filter channel 2 already seeks ways to get into the adjacent filter channel 2. This makes it possible to solve even the plug-like particle S deposition.
- Outflow device 7 flows over the time (t) and the pressure (p) shown schematically.
- the curve P1 shows the pressure curve in a normally loaded loaded with particles filter body F.
- the pressure column within the filter channels 2 is constructed at high pressure pulse-like (pulse phase IP), in particular to loosen strong compaction of particles but also the plug-like particle deposits S. Subsequently, by continuous compressed air delivery
- the pulse phases (time duration t1) or pressure hold phases (time duration t2) are designed differently in time.
- a high momentum ensures that the solidified material arranged inside the filter channels, in particular the hard deposits in the rear region of the filter channel, the so-called ash plug, comes off. Due to the pressure in the pressure maintenance phase, the dissolved mass is conveyed through the filter channel to one side, namely until it also emerges accordingly.
- the outflow device attaches directly to the filter channels of the filter body, it can be determined by a corresponding back pressure, if the filter load is high (pressure profile at too high filter loading) or if also defects within the filter (pressure curve at break within the substrate or pressure at hole on an end face) is present.
- the corresponding feedback thus already causes an immediate adaptation to the corresponding method. If, for example, sensors determine that the pressure profile does not correspond to the course of the curve P1, it is possible, based on the different pressure profiles, in particular in the pressure maintenance phase DP, to draw conclusions about the technical function of the filter body F.
- the curve P2 represents a pressure curve which corresponds to a high filter loading with particles inter alia by blocking or merging.
- the curve P3 shows a pressure curve, which suggests a break or tear within the filter, in particular within the filter channels 2.
- the curve P4 can also close a hole on the front side of the filter body F.
- the filter body F is acted upon in a first cleaning process from the filter outlet side A with compressed air via the discharge device 7.
- first deposits are already discharged on the walls and the plug-like particle deposits are at least loosened.
- Quality management takes place both off-line and online. This allows one and the same filter to be cleaned at different locations. This is made possible by the fact that the corresponding data for the life cycle of the respective filter body are available online (for example in a cloud) so that they can always be viewed from anywhere, tapped and further processed or supplemented.
- U, V, X, Y, Z are exemplary filter channels 2
