Definitions
- the invention relates to a regenerative afterburning device which comprises in a housing from top to bottom:
- a device for thermal regeneration of the heat exchanger material wherein a device for thermal regeneration of the heat exchanger material is provided, with which hot, pure gas can be passed through selected segments of the heat exchanger space until the contaminants attached to the heat exchanger material are detached therefrom.
- Regenerative post-combustion devices are used to clean contaminated exhaust gases from industrial processes.
- the exhaust gases to be cleaned are passed through heat exchanger materials. Since the exhaust gases to be cleaned often contain impurities, in particular also organic impurities in the form of condensable substances, for example tar products, or dusts, the surfaces of the heat exchanger materials become clogged with these impurities during operation.
- the heat exchanger material must be periodically heated to a temperature at which the contaminants attached to the surface can be dissolved and removed.
- accumulated impurities are understood to mean all impurities that accumulate mechanically, chemically, absorptively, adsorptively or through condensation processes on the heat exchanger material and can be removed again by a thermal process in connection with flow.
- the object of the present invention is to design a regenerative afterburning device of the type mentioned at the outset in such a way that it enables continuous cleaning operation even during thermal regeneration of the heat exchanger material.
- the device for thermal regeneration comprises:
- At least one of the segments of the burn-out rotary valve is open at the top and closed towards the rotary distributor and is connected to an outlet, while
- a drive device with which the burn-out slide can be rotated below the heat exchanger space in such a way that its segment, which is closed at the bottom, can optionally be brought into communication with each segment of the heat exchanger chamber.
- the gas flow from the rotary distributor into the segmented heat exchanger space filled with heat exchanger material is controlled by an additional element, the "burn-out rotary valve".
- This does not change the basic mode of operation with regard to exhaust gas cleaning compared to the prior art; the only difference is that the flow path from the rotary distributor into the heat exchanger space is somewhat longer than in the prior art.
- the afterburning device according to the invention it is possible to use a single segment or individual segments of the
- the burn-out rotary valve is turned so that its segment, which is closed at the bottom, communicates with the segment or segments of the heat exchanger space which is or are to be thermally regenerated. This is or are no longer periodically cooled by supplied, cool exhaust air. It heats up or they now warm up from top to bottom by the hot gas used for thermal regeneration, either from the combustion chamber of the regenerative afterburning device via the questionable segments of the heat exchanger space to be regenerated and the segment of the burn-out slide closed at the bottom to the outlet or in the opposite direction.
- the gases which flow through the segments of the heat exchanger space to be regenerated and the segment of the burn-out slide which is closed at the bottom are ultimately (again) passed into the combustion chamber, where the impurities which are released from the heat exchanger material during the regeneration process have burn.
- This process can be carried out separately for each segment of the heat exchanger room as required.
- the burn-out rotary valve is divided into (n + 1) segments, of which n is open at the top and bottom and one is open at the top and closed at the bottom;
- ba is divided on its upper side into n sectors, each enclosing an angle of 360 / n and having a passage opening which communicates with one of the n segments of the heat exchanger space;
- bb) is divided on its underside into (n + 1) sectors, each enclosing an angle of 360 / (n + 1), n of these sectors having a passage opening which, depending on the rotational position of the burnout rotary valve, with each of whose (n + 1) segments can communicate while a sector is closed and in a certain rotational position of the burn-out rotary valve is above its segment which is closed down;
- bc has n partition walls, some of which run obliquely from the top to the bottom of the transfer space in such a way that it is divided into n segments, each of which has a passage opening on the top and bottom, at least one of these segments on its underside at least partially through the closed Sector is limited.
- the burn-out rotary slide valve has one segment more than the heat exchanger space
- the burn-out rotary slide valve can have as many open and upward-open segments that participate in the exhaust gas purification as the heat exchanger space.
- the trick of the so-called “transfer space” creates the transition between the segment arrangement, as it has the heat exchanger space, and the segment arrangement, which is present in the burn-out rotary valve.
- the transition area with the closed sector provides an area under which the segment of the burn-out rotary valve which closes down can be "parked” if thermal regeneration is not to take place in any segment of the heat exchanger space.
- the burn-out rotary slide valve has a central pipe section, the interior of which has a
- Opening in its lateral surface communicates with the segment of the burn-out rotary valve which is closed at the bottom.
- the hot gas used for thermal regeneration is fed to the burnout rotary valve via the central tube piece or is removed from it.
- the middle pipe section of the burn-out rotary slide valve can be closed at the bottom and can be connected at the top to a coaxial middle pipe section of the component located above, which communicates with the connection. This means that the hot gas used for thermal regeneration is fed to the burn-out rotary valve from above or is discharged upwards from it.
- the middle tube section of the burn-out rotary slide valve it is also possible for the middle tube section of the burn-out rotary slide valve to be closed at the top and to communicate with a coaxial middle tube section of the component below, which communicates with the connection.
- a further possibility of guiding the hot gas used for thermal regeneration through the burn-out rotary valve is that the segment of the burn-out rotary valve which is closed at the bottom has an opening in its lateral surface, through which it is connected to a stationary ring channel that surrounds the burn-out rotary valve communicates, which in turn communicates with the connection.
- the hot gas used for thermal regeneration is fed to the burn-out rotary valve or its discharge from the burn-out rotary valve in the radial direction, which in turn is preferable in individual cases for geometric reasons.

- inlet 3 for the exhaust air to be cleaned, which is supplied via an inlet line 4.
- This gas enters an inlet plenum 30 and flows axially upwards in this, relative to the axis of the housing 2.
- Compensators 40 which absorb different thermal expansions, pass the gas into a rotary distributor 5, which can be set into a continuous or stepwise rotary movement by means of a drive (not shown in FIG. 1).
- the rotary distributor 5 provides a connection between the inlet 3 and one or more Segments from a multiplicity of pie-shaped segments in a distribution space 6 located in the central region of the housing 2.
- the gases also pass through a burn-out rotary valve on the way from the rotary distributor 5 to the different segments of the distribution chamber 6
- the distribution space 6 there is a heat exchanger space 7 in the housing 2, which is divided into a corresponding number of segments, each of which communicates with a corresponding segment of the distribution space 6 below.
- the segments of the heat exchanger space 7 are filled with heat exchanger material.
- a combustion chamber 8, into which a burner 9 opens, is located above the heat exchanger space 7 in the uppermost region of the housing 2.
- an exemplary embodiment of the afterburning device 1 is selected in which the heat exchanger space 7 is divided into eleven segments of equal size by radially extending partition walls, ie two adjacent partition walls each enclose an angle of approximately 32.7.
- the distribution space 6 underneath is segregated in the same way, so it also contains eleven the same large segments which communicate via openings 25 (see FIG. 2) in the partition 42 between the heat exchanger space 7 and the distribution space 6 with the corresponding segments of the heat exchanger space 7.
- the dividing wall 43 closing the distribution space 6 downward is in the central region of each segment with an opening 26 cf. Figure 2) provided.
- the transfer space 41 shown in FIG. 3 is fastened under these openings 26.
- the transfer space 41 is delimited by an upper plate 44, a lower plate 45 and a cylinder jacket surface 46.
- the upper plate 44, lower plate 45 and cylinder jacket surface 46 are only shown schematically in FIG. 3 with dashed outlines to expose the view into the interior of the transfer space 41.
- the top plate 44 of the transfer space 41 shown in plan view in FIG. 6 is provided with eleven openings of the same size, pie-shaped, 47, between which strip-shaped spaces 50 lie. Each opening 47 communicates with an overlying segment of the distribution space 6 via an opening 26 in the partition wall 43. In the middle of the plate 44 there is a circular opening 27.
- the lower plate 45 of the transfer space 41 shown in FIG. 5, on the other hand, is divided into twelve sectors, each enclosing an angle of 30. Of these twelve sectors, eleven are provided with a corresponding pie-shaped opening 48, between which stripe-shaped spaces 51 lie. The twelfth sector 49 is closed. In the middle of the plate 45 there is a circular opening 28.
- Ten of the eleven partitions 49 extend in the axial direction from the strip-shaped spaces 50 of the upper plate 44 to corresponding strip-shaped spaces 51 of the lower plate 45.
- the twelfth partition wall 49 extends from the remaining strip-shaped space 50 of the upper plate 44 to the center line of the closed sector 41 of the lower plate 45, as can be seen in FIG. 3. Since, as mentioned, the openings 47 of the upper plate 44 enclose a larger angle than the openings
- the partitions 49 for the most part do not run in an axial plane but are positioned obliquely against the axis of the transfer space 45.
- the partitions extend in the radial direction
- the purpose of the transfer space 41 is to provide not only eleven pie-shaped openings 48 on its lower plate 45 which communicate with the corresponding eleven segments of the air distribution space 6 of the heat exchanger space 7, but also beyond to create a closed sector area 41, the meaning of which will be revealed in interaction with the burnout rotary valve 31 described below.
- the burnout rotary valve 31 is shown in FIGS. 4, 7 and 8. It is delimited by an upper plate 52, a lower plate 53 and a cylindrical surface 54.
- the upper plate 52, lower plate 53 and cylinder jacket surface 54 are again only shown in broken lines in FIG. 4 in order to provide an insight into the interior of the burn-out rotary recording device 31.
- the upper plate 52 of the burn-out rotary slide valve 31, shown in FIG. 8, contains twelve equally large, pie-shaped openings 55, which therefore each enclose an angle of 30 and are separated by strip-shaped spaces 56. In the middle, the upper plate 52 has a circular opening 57.
- the lower plate 53 of the burn-out rotary slide valve 31 shown in FIG. 7 is divided into 12 sectors of equal size, 11 of which are provided with openings 58 in the form of pie pieces.
- the pie-shaped openings 58 are separated from one another by strip-shaped interstices 59.
- the twelfth sector 60 of the lower plate 53 is closed.
- the lower plate 53 of the burn-out rotary slide valve 31 has a circular opening 61.
- a central pipe section 62 extends axially from the circular opening 57 in the upper plate 52 to the circular opening 61 in the lower plate 53.
- twelve partition walls run radially 63, which are axially each of the strip-shaped Spaces 56 of the upper plate 52 extend to the strip-shaped spaces 59 of the lower plate 53 or to the edges of the closed sector 60. In this way, twelve segments are created in the burn-out rotary slide valve 31, one of which is covered downwards by the closed sector 60, but the remaining eleven of which are continuous from top to bottom.
- the pipe section 62 of the burn-out rotary slide valve 31 is connected via a radial opening 64 to the interior of the segment, which is closed at the bottom.
- the rotary distributor 5 arranged below the burn-out rotary slide valve 31 is designed in a manner known per se. Depending on its rotational position, it establishes a connection between the inlet plenum 30 and certain segments in the burnout rotary valve 31 and thus also certain segments of the transfer space 41, the distribution space 6 and the heat exchanger space 7. In addition, it connects certain other segments of the burn-out rotary slide valve 31, which are generally diametrically opposite to the first-mentioned segments, and thus also further segments of the heat exchanger space 7, the distributor space 6 and the transfer space 41 with an outlet 10 (see FIG. 1) for purified gas.
- Rotary distributor 5 via the burn-out rotary slide valve 31 and the transfer space 41 a connection between that segment of the distribution space 6 and thus of the heat exchanger space 7 with a purge air inlet 11 (see FIG. 1), seen in the direction of rotation of the rotary distributor 5
- the rotary distributor has 5 different openings, whose mouths in the upper end face of the rotary distributor 5 are shown schematically in Figure 9.
- the direction of rotation of the rotary distributor 5 is indicated by the arrow 32.
- the breakthrough for the exhaust air to be cleaned is identified by the reference number 33, the breakthrough for the purge air by the reference number 34 and the breakthrough for the cleaned air by the reference number 35.
- Rotary distributor 5 each enclosing an angle of 30 °.
- the middle pipe section 65 of the transfer chamber 41 (compare FIGS. 1 to 3) is coaxially extended by a pipe section 66 which extends through the distribution chamber 6 in the axial direction.
- the gas connection 68 is connected via a line 69, in which a blower 70 is located, to an inlet 71 at the upper region of the housing 2, which leads to the combustion chamber 8.
- a line 72 leads via a blower 73 to the chimney, which is no longer shown in the drawing, optionally via further intermediate treatment stations.
- a line 74 which is connected to the purge air inlet 11, branches off from the line 72 in the flow direction behind the blower 73.
- the described regenerative afterburning device 1 works as follows: “Normal operation” is to be understood in the following as the mode of operation in which the contaminated exhaust gases supplied via line 4 are combusted in the combustion chamber 8 and after the heat has been exchanged in the various segments of the heat exchanger space 7 via the gas outlet 10 and the line 72 to the chimney.
- the burn-out rotary slide valve 31 is in such a relative position below the transfer space 41 that its segment, which is closed at the bottom by the sector 60, comes to rest below the closed sector surface 49 of the transfer space 41. In this position, the segment of the burn-out rotary slide valve 31 that is closed at the bottom communicates neither axially downwards nor axially upwards. No gas flows outwards to or from the gas connection 68 via the opening 64, the interior of the pipe section 62 of the burn-out slide 31, the interior of the pipe section 65 of the transfer chamber 41 and via the pipe sections 66 and 67 in the distribution chamber 6.
- the rotary distributor 5 rotates below the burn-out rotary valve 31 in the usual manner either continuously or step by step from segment to segment, the exhaust gas to be cleaned sequentially corresponding to the position of the opening 33 in the rotary distributor 5 into the corresponding segments of the burn-out rotary valve 31, the transfer space 41, the distribution space 6 and the heat exchanger space 7 are guided into the combustion chamber 8.
- the gases are afterburned there in a known manner and then returned through those segments of the heat exchanger space 7, the distribution space 6, the transfer space 41 and the burn-out rotary slide valve 31 which communicate with the opening 34 of the rotary distributor 5. From there, the now cleaned exhaust gases pass through outlet 10, drawn in by blower 73, via line 72 to the fireplace.
- a portion of the cleaned gases is returned via line 74 to the purge air inlet 11 and from there via an angled line 12, which is first passed through the inlet plenum 30 and then axially through the compensators 40, in a way that is not shown in the drawing Segment of the rotary distributor 5 introduced, which corresponds to the purge air opening 34.
- This air flows on to a segment of the transfer space 41, the distributor space 6 and the heat exchanger space 7.
- the heat exchanger material contained in this segment of the heat exchange space 7 is freed of residues of the exhaust gas by the clean air flowing through, which previously contained the segment of the heat exchanger space 7 in question has flowed through, enters the combustion chamber 8 and is re-burned there.
- the “normal function” of the regenerative afterburning device 1 described does not differ in any way from that of known afterburning devices. A small difference is that the effective free flow cross-section for the gases is always somewhat reduced when one of the openings 33, 34, 35 of the rotary distributor 5 overlaps the segment of the burn-out rotary valve 31 covered by the closed sector 60. Since the flow cross-sections are still sufficiently large in this case, there are no further effects on the cleaning of the exhaust gases.
- regeneration mode is to be understood as the mode of operation in which - in addition to the further purification of exhaust gases - a certain segment within the heat exchanger space 7 is also thermally regenerated.
- burn-out Rotary slide valve 31 moved from the position described, in which the segment closed below the sector area 41 of the transfer space 41 is “parked", below that opening 48 of the transfer space 41 which corresponds to the segment of the heat exchanger space to be regenerated
- the burn-out rotary slide valve 31 is moved back into its "parking position", in which its segment closed by the sector 60 is below the closed sector 41 of the transfer space 41.
- FIG. 1 is unchanged from FIG. 1. However, instead of sucking the gas used for thermal regeneration from the combustion chamber 8 directly into the heat exchanger space 7, it is removed from the combustion chamber 8 via a side outlet 14. The hot combustion gas is over a
- Line 15 in which a control flap 16 and a blower 17 lie, is fed to the gas connection 68.
- the hot gas leaving the combustion chamber 8 is supplied with fresh air, which is introduced into the line 15 from the outside atmosphere via a further control flap 18.
- heat exchanger space 7 is flowed through from bottom to top.
- This has the advantage that the hot gases first reach the lower regions of the heat exchanger material facing away from the combustion chamber 8. That way a homogeneous temperature in the heat exchanger material required to detach the contaminants can be reached more easily and quickly.
- the gases emerging from the heat exchanger space 7 at the top, which are loaded with contaminants detached from the heat exchanger material, are post-combusted in the combustion chamber 8 together with the exhaust gas, which is in the normal cleaning process.
- FIG. 12 shows an axial section through a second exemplary embodiment of a regenerative afterburning device, which is very similar to that of FIG. 1. Corresponding parts are therefore identified by the same reference numerals as in FIG. 1 plus 100.
- the regenerative afterburning device 101 of FIG. 12 differs from that of FIG. 1 only in the manner in which the gas used for thermal regeneration is guided in the region of the burnout rotary valve 131. While, as explained above, in the exemplary embodiment in FIG. 1, that segment of the burn-out rotary slide valve 31 which passes downward through the sector 60 is closed, was opened radially inwards to the middle pipe section 62, there is no connection in the embodiment of Figure 12 in this direction, as can be seen in particular the partial enlargement of Figure 13. Instead, the segment in question is open radially outwards; the cylinder jacket surface 154 of the burn-out rotary slide 131 therefore has an opening 121 at this point.
- the burn-out rotary slide 31 is surrounded by an annular channel 122 which is rigid with the housing 102 or the separating plate 143 on the underside of the distribution space 106 is attached.
- a pipe section 167 connects the ring channel 122 to the gas connection 168 on the outside of the housing 102.
- This gas flow can be reversed in the thermal afterburning device 101 from FIG. 12 in the same way as is shown in FIG. 10 for the exemplary embodiment of a thermal afterburning device 1 described first. This is shown in Figure 14.
- the air used for the thermal regeneration can be taken directly from the outside atmosphere and, via a blower 120 and a burner 119, the gas inlet 168 be fed. This is shown in Figure 15.
- FIGS. 16 and 17 show a third exemplary embodiment of a thermal afterburning device, which again has great similarity to the exemplary embodiment from FIG. 1. Corresponding parts are therefore provided with the same reference number, plus 200. Again, the only difference is the guidance of the gas used for thermal regeneration in the area of the burn-out rotary valve 131. While in the exemplary embodiment described first, the interior of the middle pipe section 62 of the burn-out rotary valve 31 with the central pipe section 65 of the transfer pipe lying above it - Room 41 communicated, in the exemplary embodiment of FIGS. 16 and 17, the middle tube piece 262 of the burn-out rotary valve 231 is closed at the top and opened at the bottom.
- a pipeline 229 which runs coaxially to the housing 2 and in some areas also coaxially to the purge air line 212 through the compensators 240 to the underside of the housing 202. There branches off at a right angle from a line 267 which leads radially outwards to a gas connection 268.
- the gas connection 268 is connected to the upper inlet 271 of the thermal afterburning device 201 via a blower 270, which is located in a line 269, in the same manner as in FIGS. 1 and 12.
- FIG. 18 shows a guidance of the gas used for thermal regeneration corresponding to that in FIGS. 10 and 14 described above;
- FIG. 19 shows the use of air taken from the outside atmosphere and heated in a separate burner 219, corresponding to FIGS. 11 and 15, to which reference is made.
