Definitions
- the invention relates to an exhaust gas purification system for diesel engines according to the preamble of the main claim and a method for exhaust gas purification according to the preamble of claim 14 1
- a fundamentally different solution for the regeneration of the filter is to burn off the soot by means of an additional burner, which is switched on when necessary and burns the soot through the burner gases (compare, for example, DE-OS 3219948).
- the particular problem here is to adapt the burner function to the respective operating state, namely the amount of exhaust gas, the exhaust gas temperature and the exhaust gas pressure of the engine gases. Even slight deviations from the required coordination can lead to thermal damage or destruction of the filter.
- the invention consists in the fact that the filter device consists of a plurality of preferably equidistantly arranged, tubular filter elements, one end side of which can be closed, that the housing receiving the filter element is divided into two rooms by a partition wall in such a way that the filter tubes in the first part space and the open ends of the filter tubes lie in corresponding openings in the partition, and in the second part space a fixed regeneration chamber of the fan burner is formed by partitions.
- the regeneration chamber can preferably be designed as a combustion chamber of a burner for generating hot combustion gases. Alternatively, the exhaust gases can finally be fed into the second subspace and the exhaust gases removed from the first subspace.
- the filter elements consist of filter tubes which are bundled rotationally symmetrically around a central axis and are accommodated in a cylindrical housing, the central axis being mounted in the housing as an axis of rotation.
- the partition walls present between the burner chamber and the second sub-chamber are expediently arranged to extend radially from the axis of rotation to the inner wall of the housing, so that a sector-shaped burner chamber is created.
- Ceramic wound filters or steel wool filters can also serve as filter elements according to the invention.
- the supplied exhaust gases to be cleaned flow through the filter tubes and through their walls into the second sub-space to the drainage connection and in this case repaint the filter tubes assigned to the regeneration sector, which are decoupled from the exhaust gas cleaning system.
- the regeneration burner can also be switched on when the internal combustion engine is started, so that the cold exhaust gases are heated by the heated tubes, so as to prevent the smoke burst which is usual when the machine is still cold. This advantage does not exist in known devices.
- the filter tubes can be mounted on one or two sides. With one-sided clamping, the filter tubes can expand freely and thereby reduce stress; If the filter tubes are mounted on both sides with fixed and loose sides, the filter tubes can also expand freely and there are no additional loads on the ceramic material due to vibrations that could affect the housing.
- the type of storage of the filter tubes is adapted to the need.
- the cleaning capacity can be adapted to the actual accumulation of residual quantities in that the clock frequency can be changed as the filter block continues to rotate depending on the time-averaged engine load.
- the filtered exhaust gases for cooling or for temperature control are advantageously passed over the regeneration area, as a result of which temperature overload is avoided and dew point problems when the temperatures are too low are avoided.
- Fig. 1 shows a section through the invention
- FIG. 2 shows a section along line II-II in FIG. 1st Fig. 3 is a perspective view of the new
- Figure 1 shows a preferred embodiment of the invention.
- the filter block is accommodated in the cylindrical housing and consists of the individual filter tubes 2, which are arranged rotationally symmetrically and axially parallel around the central axis 3.
- the central axis 3 is mounted as a shaft in the housing 1.
- the ends of the filter tubes 2 on the left in the illustration in FIG. 1 are inserted into the disk-shaped wall 4 and either as shown in the dash-dotted circle, thereby closed on one side, or the tubes 2 penetrate the wall 4 and are in themselves closed.
- the housing 1 is further divided by the partition 5 into two sub-rooms 6 and 7 sealed from one another.
- the free ends of the filter tubes 2 are mounted in the partition 5 in such a way that in this case their openings are aligned with the end face of the partition 5 facing the partial space 6, as can be clearly seen from FIG. 3.
- the sub-space 6 serves as a supply space for the exhaust gases to be cleaned, while in the sub-space 7 the exhaust gases are filtered by means of the filter tubes 2.
- FIG. 6 clearly shows the formation of the regeneration room.
- the exhaust gases to be cleaned are supplied via the connector 12 and the cleaned exhaust gases are removed via the connector 13.
- the filter block consisting of the individual filter tubes and the walls 4 and 5 can be rotated in the housing 1 by means of the schematically indicated motor 14 .
- the filter block is in the position shown in FIG. 1.
- the exhaust gas flows in the direction of arrow 15 through the connector 12 into the space separated from the regeneration space and from there via the openings 16 of the filter tubes 2. Since the filter tubes 2 are closed off at the opposite end, the exhaust gases are forced through the filter walls to penetrate, 'over the entire length of the filter tubes, so that you have large effective filter areas. When the gases flow through, the floating particles, ie the soot, settle on the inner wall of the filter tubes.
- the exhaust gases cleaned by the filter tubes flow around the filter tubes belonging to the regeneration sector on their way to the drain connection 13, thus have a cooling effect on them and combine with the regeneration gases in order to drain them in the direction of the * arrow 17.
- the filter block is rotated further by a sector width by means of the motor 14. It is of course also possible to continuously rotate the filter block instead of the cyclical rotation.
- Sealing means 18 are arranged between the filter block and the housing in order to prevent uncleaned exhaust gases from entering the regeneration space. This also applies to the slots between the fixed partition walls 8 and 9 and the movable filter block, for which there is a strip seal, not explained in more detail, over which the end face of the partition wall 5 slides. To reduce the wear between the seals and the partition 5, it is advantageous to relieve the seals by slight axial displacement during the rotation. This can be done, for example, by axially displacing the shaft 3 using suitable means which are not described in more detail.
- the lifting off can also only be kept insignificant, or be completely omitted, so that the rotating surfaces rub against one another, so that the soot on the end faces of the The filter tubes are scraped off and cleaning of these surfaces is achieved.
- the described seals 18 must then be correspondingly resistant.
- the filter tube is cleaned in the described
- Example in cycles it is possible to use the cycle time, i.e. to determine the time of the regeneration and to make it dependent, for example, on the state of loading of the filter tubes with soot.
- the loading condition must then be checked and measured, which can be done by measuring the pressure by determining the pressure difference between the static pressures upstream and downstream of the regeneration sector.
- the measuring probes 19 and 20 which are used for this purpose are indicated schematically in FIG.
- the pressure difference can be measured when the burner has just started (hot process) or the burner air has just started (cold process).
- the differential pressure measurement is safer by having a defined burner air flow and not being dependent on the changing operating conditions of the engine exhaust gases.
- Another measure known per se can also be applied to the new exhaust gas purification system, namely coating with catalytically active substances.
- This has the advantage that the hydrocarbons adsorbed in the soot are completely burned. This is particularly necessary if the desorption of the hydrocarbons by heat conduction takes place faster than the burning process, ie the exhaust gases would otherwise it should not be burned sufficiently. It is advantageous and expedient if the catalytic coating is provided on the outflow side of the filter.
- a variation useful for certain applications can be the reversal of the flow direction of the exhaust gases, i.e. that the exhaust gases are introduced into the nozzle 13 and flow out cleaned from the nozzle 12.
- the exhaust gases flow around the filter tubes 2 and penetrate through their walls, so that the soot is deposited on the outer surface of the filter tubes 2.
- FIG. 4 shows such an exemplary embodiment, with only the inlet connection 21 being offset with respect to the outlet connection 13 with respect to FIG. 1. Otherwise, this system works exactly like the system described in FIG. 1, so that a further explanation is not necessary.
- FIGS. 1 to 5 show such a modification in which the burner 22 acts on the circumference of the filter block.
- partitions are required in the filter block, as indicated in the previous example. Deposits of the residual particles and supply of the hot burner gases are also carried out in direct current. A detailed description is unnecessary since the mode of operation of this example corresponds to the previously described embodiment.

Abstract
Le système décrit comporte une unité de filtrage pour séparer la suie des gaz d'échappement, et un dispositif de régénération destiné à l'unité de filtration. Cette dernière comprend des tubes de filtration (2) qui sur un côté sont fermés. Ainsi, les gaz d'échappement peuvent être introduits de l'autre côté et pénétrer dans les cloisons de filtration. Ce faisant, la suie se dépose sur la surface intérieure des tubes de filtration (2). Il est prévu un brûleur (11) pour produire les gaz de brûlage de la suie, ces gaz n'étant appliqués, par suite d'agencements appropriés, que sur un seul secteur à la fois du bloc filtrant. L'admission (15) et l'évacuation (17) des gaz d'échappement sont choisies en sorte que les gaz d'échappement purifiés s'écoulent autour des tubes filtrants (12) qui sont soumis à la régénération. Le sens d'écoulement des gaz d'échappement peut également être inversé, de sorte que les gaz d'échappement s'écoulent tout d'abord autour des tubes filtrants (2) et atteignent, par l'intermédiaire des cloisons, l'intérieur, puis s'écoulent de là via les ouvertures de tube jusqu'à la sortie. Ce faisant, la suie se dépose sur la face extérieure des tubes filtrants.The system described comprises a filtering unit for separating the soot from the exhaust gases, and a regeneration device intended for the filtration unit. The latter comprises filtration tubes (2) which on one side are closed. Thus, the exhaust gases can be introduced on the other side and penetrate into the filtration partitions. In so doing, the soot is deposited on the inner surface of the filtration tubes (2). A burner (11) is provided for producing the soot burning gases, these gases being applied, as a result of appropriate arrangements, only on one sector at a time of the filter block. The intake (15) and the discharge (17) of the exhaust gases are chosen so that the purified exhaust gases flow around the filter tubes (12) which are subjected to regeneration. The direction of flow of the exhaust gases can also be reversed, so that the exhaust gases first flow around the filter tubes (2) and reach, via the partitions, the interior , then flow from there through the tube openings to the outlet. In so doing, the soot is deposited on the outside of the filter tubes.
