Abstract

The rectangular flow-duct (18) has several nozzles (24) positioned on the two opposite-facing walls (26) defining the flow-duct and lying on one plane (22). The flow duct has a transition part (20) from a combustion chamber (12) of the combustion plant to the flue gas outlet (10). At least one wall section (28) of the two facing walls have first nozzles (24a) in a row and form an angle between the wall and jet.

Description

The invention relates to a device for generating a rotating flow in a flow channel, the a flue gas exhaust from an incinerator, in particular a waste incineration plant, according to the Preamble of claim 1.

Such devices are used to by means of injected the composition of the media by the Removed flow channel of an incinerator Flue gas mixture and its temperature as well as its Regulate dwell time. However, composition, Temperature and dwell time are not only regulated but pre-set everything be evened out. That way optimal afterburning of the flue gas mixture guaranteed and can achieve the desired, low Emission values are observed. For this is one complete mixing of the flue gas mixture necessary. By generating rotating currents in the flow channel with the help of devices corresponding nozzle arrangements are tried to achieve complete mixing.

A generic device is for example from US-A-5 252 298. The arranged in one level Nozzles are tangent to one in the middle of the Flow channel imaginary circular line aligned so that a rotating flow is generated in the flow channel. In a device known from DE-A-19 648 639, the flow rate by means of each other in the flow channel controlled opposite arranged nozzles in such a way that at least two oppositely rotating currents in the Flow channel arise. The problem with these known rotating currents is that in the middle the flow creates an almost vortex-free eye, so that no complete mixing and therefore no uniform composition, temperature distribution and Retention time is obtained.

The object of the present invention is therefore a to provide economical device with which is a complete mixing of flue gas mixtures is obtained in the flow channel of an incinerator. This task is accomplished by a device according to the features of claim 1.

Due to the special arrangement of first nozzles according to claim 1 in an injection plane in at least one first wall section per wall, which is obliquely opposite the at least one first wall section of the opposite wall, and by the alignment of the first nozzles in the injection plane in such a way that that in the injection plane lying angle between the wall and an injected jet is at least approximately 90 °, on the one hand a rotating flow is generated in the flow channel and on the other hand very good mixing of the flue gas mixture is achieved. With

Figure 00020001
diagonally opposite "means that the first wall sections for swirling the flowing material in the projection, for example in the direction of the jet flowing in through the first nozzles, do not overlap or only partially overlap. In particular when the first nozzles are distributed over first wall sections with a length l of 50% and more ensures that jets of injected media reach the center of the flow channel by the sum L of the lengths of the first wall sections of a wall being at least approximately 40% up to 80% of the total wall width b, ie by First nozzles extend only over a portion of the width b of the wall, material and assembly costs for the nozzles are saved, while the efficiency of the mixing is maintained.

In a special embodiment are in the Injection level in addition to the first nozzles in one second wall section at an angle β with respect to first nozzles and obliquely towards the center of the Flow channel aligned second nozzles provided, which further improves the mixing.

Preferably, there are several first and special ones per wall preferably also a plurality of second wall sections with first ones or second nozzles provided so that vortex areas with counter-rotating vortices are generated, which the Mixing improved even further.

It is particularly advantageous to use the second nozzle in one Angle α with respect to the injection plane Align the injection component in the downstream direction. Each of the second nozzles can have one Injection component a different angle α compared to Have spraying plane or spray all second nozzles with a injection component into the same by the angle α plane tilted in relation to the injection plane in the Flow channel. That is how the rays are these nozzles are adjustable so that they are helical flow into each other.

In a further preferred embodiment are on all four walls delimiting the flow channel first Nozzles arranged in a first wall section. there are the first wall sections in the circumferential direction against the rotating flow at the beginning of each Wall so that it is from the first wall section of the adjacent wall are spaced and not each other touch. This distribution of the first wall sections and their length of more than 0.5b can be a very good one generate rotating flow and by injecting all four sides to the center of the flow channel optimal mixing of the flue gas mixture to reach.

It is particularly advantageous to use the nozzles on all four walls to be arranged in an injection plane. But the nozzles can also in two parallel to each other in the direction of flow spaced injection levels may be arranged, each other opposing nozzles are arranged in one plane.

Ideally, they are point symmetric opposite wall sections of the same length.

Fresh secondary air and / or are advantageous recirculated flue gas injected. If fresh Secondary air and recirculated flue gas are injected, annular gap nozzles are preferably provided. There is the core jet of the annular gap nozzles from recirculated Flue gas and the ring jet from fresh secondary air.

A control system with which is particularly advantageous Help the throughput of the media to be sprayed at least for opposite walls arranged nozzles can be controlled independently.

If at least one injection level in the area of a Transitional area between a combustion chamber and the Flue gas flue from the incinerator is arranged, by spraying the to be atomized Media in addition to the mixing and regulation of the Flue gas mixture a cooling of a very high Flame blanket exposed to thermal stress is reached. Other advantageous embodiments are the subject further dependent claims.

The invention is explained in more detail below with the aid of a few selected examples. 1 to 6 show purely schematically:

1a to 4a are of a waste incineration plant each a section of a flue gas outlet 10 and a combustion chamber 12 and a transition area 20 between Combustion chamber 12 and flue gas outlet 10 with a flame blanket 14 shown in section along the flue gas outlet 10. For the deduction of incurred during combustion Flue gas mixtures is a rectangular flow channel 18 provided that the transition region 20 from the Combustion chamber 12 for the flue gas outlet 10 and the flue gas outlet 10 includes. The basic flow direction of the Flue gas mixture is indicated by an arrow 16. 1b to 4b are cross-sections to Flow channel 18 shown in the area of an injection plane 22, in which nozzle 24 for injecting sprayable media are arranged. The nozzles 24 and their orientation are in all representations represented by arrows. The The direction of waste flow is indicated by an arrow 9.

All of the embodiments shown in FIGS. 1 a to 4 b have first wall sections 28 with a length l 1 of at least approximately 40% to 80% of the wall width b of a wall 26 on at least two walls 26 lying opposite one another. The first wall sections 28 lie with the central longitudinal axis 32 of the flow channel 18 as a symmetrical axis of symmetry with respect to one another and are delimited on one side by the adjacent wall 26. First nozzles 24a are arranged in a row in an injection plane 22 in the first wall sections 28, which are opposite one another in a point-symmetrical manner. The first nozzles 24a are aligned in the injection plane 22 so that they inject into it, the angle γ lying in the injection plane between the injected jet 30 and the wall 26 being approximately 90 °. This arrangement of nozzles 24 enables thorough mixing of the flue gas mixture which is excited to rotate in the flow channel 18 and flows in the direction 16.

In all examples, the injection plane 22 lies in the area of the flame blanket 14, which is arranged in the transition area 20 between the flue gas outlet 10 and the combustion chamber 12. The flame blanket 14 is either itself penetrated by nozzles 24, as shown in all four examples, and / or it is via nozzles 24a ', 24b'', which are arranged in walls (26) laterally below the flame blanket (14), with sprayable media 2 to 4, as shown in FIGS. 2 to 4. In this way, the flame blanket 14 can be cooled by the injected media.

1 a and 1 b show an embodiment in which first wall sections 28 with a length l 1 of approximately 40% to 50% of the wall width b are provided on two mutually opposite walls 26. In a second wall section 34 of length l 2 , in addition to the row of the first nozzles 24a in the first wall section 28, there are second nozzles 24b which are oriented at an angle β with respect to the first nozzles 24a obliquely towards the center of the flow channel 18 represented by the central longitudinal axis 32 are. The angle β is about 25 ° in this example, but it can be between 20 ° and 50 °. The lengths l 1 and l 2 of the two wall sections 28, 34 add up to the entire wall width b in this example, but this need not necessarily be the case. Compared to the injection plane 22, the second nozzles 24b are aligned in a common plane 36 which is tilted by the angle α relative to the injection plane 22. The angle α is about 10 ° in this example, but can vary and be between 5 ° and 15 °. The second nozzles 24b are aligned in such a way that the jets 30 generated by them flow helically into one another. Instead of a common plane 36, the second nozzles 24b can also be tilted with individual angles α relative to the injection plane 22.

An embodiment is shown in FIGS. 2a to 2c shown in which on all four walls 26 of the Flow channel 18 first nozzles 24a in a first Wall section 28 and second nozzles 24b in a second Wall section 34 analogous to that in FIGS. 1a and 1b illustrated embodiment are arranged. The first Wall sections 28 are opposed in the circumferential direction of the rotating flow at the beginning of a wall 26 arranged. The nozzles 24a, 24b and 24a ', 24a' ', 24b', 24b '' are parallel in two, in the direction of flow spaced-apart injection planes 22 and 22 * arranged, with nozzles 24 on opposite one another Walls 26 in a common injection plane 22, 22 * are arranged. The distance d between the injection planes 22, 22 * can be between 0.4m and 3m.

In the example shown in FIGS. 3a, 3b, first wall sections 28 with first nozzles 24a are arranged in a single injection plane 22 on all four walls 26 of the flow channel 18. The length l 1 of the first wall sections 28 is well above 0.5b, preferably 0.55b to 0.75b. The rest of each wall 26 remaining over the entire wall width b is free of nozzles 24. This arrangement and alignment of the first nozzles 24a make it possible to jet 30 into the center of the generated rotating flow, so that a complete mixing of the flue gas mixture takes place .

Depending on the design of the flow channel 18 and Design of the walls 26 may be necessary, be it for an optimization of the flow or also because the four Walls 26 are not in a single plane with nozzles 24a can be equipped, the nozzles 24a instead of in one single injection level 22 (see. Fig. 3a, 3b) in two to arrange parallel injection planes 22 and 22 * as shown in Figures 4a, 4b.

All nozzles are designed so that media to be injected with a pressure of 500 Pa to 5000 Pa can be injected.

In Fig. 5, an annular gap nozzle 24 * is shown as it for example for injecting fresh secondary air and recirculated flue gas is provided. One is shown first feed line 40 for supplying a first Medium, in this case recirculated flue gas, into one trained as a core nozzle 42 and a core jet producing nozzle part and a second feed line 44 for the supply of a second medium, in this case fresh secondary air, in an annular gap 46 trained and producing a ring beam Nozzle part.

Via a control system 48, as shown in FIG. 6 for Annular gap nozzles 24 * is shown, the different conditions as they are on different Sides of the flow channel 18 can prevail, better Be taken into account. The throughputs of the Media to be injected are via the control system 48 and the valves 54 in the example shown for the regarding Waste flow 9 upstream half 52 and the Half 50 of the flow channel 18 located downstream independently controllable. One would also be conceivable separate control of the throughputs for the nozzles 24 on all four walls 26.

In order to regulate the temperature, the O 2 content and to obtain the longest possible dwell time of the flue gas mixture flowing through the flow channel, nozzles 24 for secondary air and nozzles 24 for recirculated flue gas are preferably provided. These nozzles 24 can either be arranged mixed in a row next to one another or also in two rows one above the other, so that there is a separate injection plane 22 for each nozzle type 24. If annular gap nozzles 24 * are provided, the core jet consists of flue gas and the ring jet consists of secondary air, as described for FIG. 5.

The embodiments shown here give the invention not finally again. For example, it is possible the device also in incinerators and Use waste incineration plants where the Transition area 20 between combustion chamber 12 and Flue gas discharge 10 characterized by a constriction is. Further injection levels 22 can also be located deeper in the Combustion chamber 12 or further up in the flue gas outlet 10 be provided. Instead of or in addition to flue gas and Secondary air can also use other media such as water vapor Activated carbon, hearth coke (HOK), waste z. B. in the frame a recycling of residues, fuels etc. injected become. Also to maintain a reducing atmosphere the device can be used. In the same Direction of rotation like the first nozzles 24a can burners 2m to 3m above the injection level 22 at two each other opposite walls 26 may be arranged.

FIG. 7 shows a further embodiment of the device according to the invention, in which two vortices 60 ', 61' rotating in opposite directions are generated. The device emerges from the device shown in FIG. 2b by reflection on the lower wall 26, ie the first and second nozzles shown there are doubled. The walls 26 of the device each have two first wall sections 28a1 and 28a2 or 28b1 and 28b2 with first nozzles 24a. The first nozzles 24a of the first wall sections 28a2, 28b2 in the lower half of the cross section are arranged obliquely opposite one another and produce a clockwise rotating vortex 61 '. This is reinforced by the second nozzles 24b of the second wall areas 34a2, 34b2. The second nozzles 24b radiate in a direction which is offset by +/- β from the jet direction of the first nozzles. These second wall areas 34a2, 34b2 are also diagonally opposite one another. The wall areas in the lower half of the cross section shown define a first swirl area 61. A second swirl area 60 is defined by the first and second wall sections 28a1, 28b1, 34a1, 34b1 in the upper part of FIG. The second vortex 60 'there rotates counterclockwise. The first wall sections 28a1, 28a2, 28b1, 28b2 each have a length l 1 . An overall length results for each wall 26 L = l 1 + l 1 of about 0.5b. The first wall sections 28a1 and 28b1 (second vertebra 60 ') or 28a2 and 28b2 (second vertebra 61') lying diagonally opposite one another determine the direction of rotation of the vertebra 60 ', 61'. The second nozzles 24b then jet in such a way that they intensify the rotation, ie tangentially in the direction of rotation to an imaginary circle around the center of the vortex 60 'or 61'.
