Definitions
- the invention relates to a regenerative exhaust air purification device, with at least one heat bed, which is flowed through by a first medium representing exhaust air flow.
- the invention further comprises a method for producing a regenerative exhaust air purification device.
- Regenerative exhaust air purification devices of the type mentioned are known. They are used to thermally clean exhaust air contaminated with pollutants. For this purpose, a fuel is often introduced into the exhaust air stream and then burned. As a result of this combustion or oxidation of the exhaust air, the pollutants are bound and can be released into the environment without causing environmental damage. Frequently, these exhaust air purification devices are designed to be renewable. This means that some of the heat contained in the exhaust air is returned to the combustion or oxidation process. For this purpose, a heat bed is provided, which can be arranged both before and after a combustion chamber in which the combustion or oxidation of the exhaust air takes place.
- the heat bed While the heat bed is arranged downstream of the combustion chamber in the flow direction of the exhaust air, it is heated by the hot exhaust air flowing out of the combustion chamber. Once the heat bed has reached a certain temperature, it is placed in front of the combustion chamber. Thus, the exhaust air, which is initially still at a low temperature level, flows through the bed of heat before it is introduced into the combustion chamber. When flowing through the heat bed, heat from the heat bed is applied transmit the exhaust air so that it heats up. Since the exhaust air is already at a higher temperature level, less energy must be supplied in the form of fuel in the combustion chamber in order to carry out the combustion or the oxidation. In this way, the temperature of the exhaust air, which is released into the environment, lowered and at the same time significantly increases the efficiency of the exhaust air purification device. In particular, the fuel consumption can be significantly reduced. However, the case may arise, in particular with a small temperature difference between the heat bed and exhaust air, that heat can not be introduced from the heat bed into the exhaust air, or only with a low efficiency.
- part of the heat generated in the combustion chamber is also to be used for other purposes.
- a waste heat boiler with pipe transfer surfaces used.
- the hot exhaust air flows through the waste heat boiler, whereby heat is withdrawn through the pipe transfer surfaces or fed to another fluid.
- This procedure is relatively inefficient, since the hot exhaust air from the combustion chamber or the exhaust air after the heat bed must first be passed into the waste heat boiler. Under the condition mentioned above, this effect is exacerbated by the fact that heat can only be transferred from the heat bed to the exhaust air with a low temperature difference between the heat bed and exhaust air, for example. It is therefore an object of the invention to propose a regenerative exhaust air purification device with the features of the preamble of claim 1, can be provided in the existing heat in an efficient way other uses.
- At least one heat exchange tube carrying a second medium runs through the heat bed to form a heat exchanger having separate media streams, wherein the media streams are formed by the first and the second medium.
- a warm or hot exhaust air flow which is a first medium
- a heat exchange tube which can be traversed by a second medium.
- the first and second media are not in fluid contact with each other so that there are separate media streams formed by the first and second media.
- the heat exchange tube is provided in the heat bed in such a way that a heat exchanger is realized with which heat can be transferred from the first medium to the second medium and heats it with it.
- a development of the invention provides that the media streams are provided at the same time or with a time delay. This means in the first case that the first and the second media stream are present at the same time. This results in a continuous heating by the first medium and a similar cooling by the second medium. But it can also be provided that the media streams are provided with a time delay. In this case, it is conceivable that first the heat bed is heated by the first medium, and the second medium is passed through the heat exchange tube only after reaching a certain temperature of the heat bed. It is also possible that a flow of the first and the second medium is provided cyclically. First of all, therefore, the heat bed is heated by the first medium, the medium stream formed by the first medium is interrupted, and then the second medium is passed through the heat exchange tube, so that heat is taken from the heat bed heated by the first medium.
- the heat bed has a, in particular flow channels for the first medium forming honeycomb structure.
- the heat bed therefore has a honeycomb structure, in particular in cross section. This can be uniform or irregular.
- the honeycomb structure provides a large surface area of the heated bed that can be used to transfer heat. In particular, a high structural stability with low weight and the mentioned large surface is achieved by the honeycomb structure.
- loading Preferably, it can be provided that the honeycomb structure forms flow channels for the first medium. This means that flow channels are formed in the heat bed, which can be flowed through by the first medium. By dividing the heat bed with a honeycomb structure, a large number of flow channels can be formed.
- a development of the invention provides that a coating, in particular nano-coating, of the heat bed, in particular of the honeycomb structure, is provided.
- a coating in particular nano-coating, of the heat bed, in particular of the honeycomb structure.
- the surface available for heat transfer can be further increased. This is especially the case when a nano-coating is used.
- a nano-coating is a coating that contains or consists of nanoparticles.
- the coating of the heat bed is provided such that surfaces of the flow channels have the coating. If the flow channels for the first medium are defined by the honeycomb structure, it is of course also possible for the honeycomb structure or the flow channels formed by it to have the coating.
- the coating can have various positive properties.
- the coating can have a catalytic effect on the exhaust air flow, so that oxidation of the exhaust air flow can already use in the heat bed, or carried out in the combustion chamber Oxidation is intensified.
- the coating of a highly thermally conductive material is formed so that the transfer of heat from the first on the second medium, or on the heat bed, is improved.
- the heat bed consists of at least one shaped body, in particular the flow channels for the first medium.
- the heat bed can consist of a single molded body, but it is preferably composed of several moldings. In this case, an arrangement of the moldings can be carried out both vertically and horizontally. Preferably, the moldings are not firmly connected to each other, so that resulting from temperature differences voltages can be compensated.
- the flow channels of the heat bed can be provided in the at least one shaped body. If a vertical juxtaposition of the shaped bodies is provided, it is preferably to be ensured that the flow channels of the shaped body are in fluid contact with the flow channels of a further shaped body.
- a shaped body may have a honeycomb-shaped structure, which in particular forms the flow channels for the first medium.
- the shaped body is a shaped block, in particular made of ceramic.
- the molded body can be made of any materials. However, preference is given to a production from an inorganic, fine-grained raw material, in particular ceramic. These substances are characterized by a very high temperature resistance or thermal shock resistance.
- a development of the invention provides that the heat exchange tube in a townixierohrohuf swipekanal the heat bed and / or the shaped body is arranged.
- the heat exchange tube is therefore not provided directly in the heat bed and / or the molded body. This is due to the fact that a way to compensate for temperature stresses should be created. If the heat exchange tube were arranged directly in the heat bed and / or the shaped body, damage to the heat exchange tube or the heat bed could occur, caused by different coefficients of thermal expansion of the heat bed and heat exchange tube.
- the heat exchange tube is arranged in a heat exchange tube receiving channel, wherein the heat exchange tube is at least partially spaced from an inner surface of the heat exchange tube receiving channel.
- a size of the distance can be selected depending on the expected operating temperature range.
- the housing of the heat exchange tube is provided in the heat exchange tube receiving channel when the heat exchange tube is not rectilinear, so in addition to the thermal stresses in the radial direction of the heat exchange tube can also occur in the axial direction.
- the heat exchanger tube receiving channel is formed in a side surface of the heat bed and / or the shaped body, in particular as an open-edged recess.
- the heat bed and / or the molded body can have an opening of the heat exchange tube receiving channel in a side face. Through this opening, the heat exchange tube can be introduced into the heat exchange tube receiving channel.
- the heat exchanger tube receiving channel is formed as an open-edged recess in a side surface of the heat bed and / or the shaped body is. This means that the heat exchange tube can be easily inserted into the heat exchange tube receiving channel during assembly of the exhaust air purification device. This procedure is particularly advantageous if the heat bed consists of several molded bodies.
- the heat exchange tube In this case, only in a juxtaposition of the molded body, either in the horizontal and / or vertical direction, the heat exchange tube must be inserted into the respective heat exchange tube receiving channel of a shaped body. By subsequently adding another shaped body, the heat exchange tube is securely held in the heat exchange tube receiving channel.
- the shaped body has at least one spacing element, in particular for a spacing position to an adjacent shaped body.
- the spacing element can be arranged on any side of the shaped body. It can be provided that the flow channels of adjacent, in particular stacked, moldings do not connect directly to each other by the spacer element. In this case, a fluid exchange between adjacent flow channels or moldings take place, so that a mixing of the flowing through the flow channels first medium may be present.
- the spacing element may also be designed such that it can compensate for a movement of two shaped bodies directed against one another, for example caused by temperature stresses, by permitting a movement of the shaped bodies relative to one another.
- a contact surface, at which the spacer element of a shaped body comes into contact with another shaped body comparatively be small.
- the spacing element can also serve to maintain a spacing to a base surface or to outer walls of the heat bed, so there is no limitation of the spacing on an adjacent molded body.
- the recess is formed by the spacing element or a plurality of spacer elements.
- the spacing elements are in the form of feet, between which there are recesses which can be used as a heat exchanger tube receiving channel.
- the spacing elements can also be provided on the other side of the molding. The dimension of the spacing element can thus also be used to set the distance between the heat exchange tube and the surface of the heat exchanger tube receiving channel in order to take account of the resulting temperature voltage.
- a development of the invention provides that a plurality of flow technology connected, a heat exchanger total pipe forming heat exchange tubes are provided. So it is not necessary for a single heat exchange tube to go through the entire heat bed. Rather, it may be provided to position a plurality of heat exchange tubes in the heat bed and connect them together to form a total heat exchange tube.
- the heat exchange tubes can be connected to each other both sequentially and in parallel.
- An example of a sequential arrangement is one of a plurality of successively arranged heat exchange tubes composite heat transfer tube, which passes through the heat bed.
- the heat bed can be penetrated by individual heat exchange tubes, which are connected to one another outside the heat bed, for example, and thus form a total heat exchange tube.
- the heat exchange tube is arranged in at least one, in particular horizontal or vertical, plane of the heat bed.
- This sectional plane is in particular aligned horizontally or vertically in order to be able to arrange the heat exchange tube in recesses formed by the spacing elements between the shaped bodies.
- the heat exchange tube is arranged in several levels. These can also be aligned horizontally or vertically. It is envisaged that the heat exchange tube establishes a connection between the planes.
- a heat exchanger can be formed at different vertical or horizontal positions of the heat bed.
- the second fluid is brought to different temperatures, or that the transmitted amount of heat is increased by an extension of the heat exchange tube. It may also be provided to determine a temperature profile of the heat bed and to use this to keep the second fluid at a constant temperature despite a cooling of the heat bed. This can be realized by passing the second fluid through a heat exchange tube located at a desired temperature level.
- a further development of the invention provides that there are provided a plurality of heat beds which can be acted upon cyclically with the first fluid and are provided with or without heat exchange tubes.

- a development of the invention provides that the heat bed is arranged before and / or after a combustion chamber.
- the heat bed having a heat exchanger can be arranged in front of the combustion chamber from a flow view. This means that the first medium first flows through the heat bed and only then into the combustion chamber. Alternatively, it can also be provided that the heat bed is arranged after the combustion chamber. In this case, due to the heat produced during combustion or oxidation, a higher temperature level of the second medium in the heat exchanger can be achieved.
- the first medium flows through the first Combustion chamber, where it is possibly provided with fuel and burned or oxidized before it flows through the heat bed, in which the heat exchanger is provided.
- a development of the invention provides that the heat exchange tube runs at least in sections in a horizontal cross section of the heat bed and / or shaped body. This means that, for example, a horizontal cross section of the heat bed is at least partially penetrated by the heat exchange tube, that is to say advantageously from one side of the cross section to another.
- a development of the invention provides that the heat exchange tube is bent and / or curved.
- a portion of the heat exchange tube arranged in the heat bed can be lengthened. It is, for example, a meandering course, or a course, which is shaped substantially in a spiral, providable.
- a helical course can also be realized.
- the heat exchange tube does not necessarily have to run in one plane. It can be provided, for example, that via a bend and / or curvature of the heat exchange tube, a connection is made from one heat exchange tube having the plane to another.
- a development of the invention provides that an additional container is provided, in which the heat bed is arranged. It is therefore not necessary for the thermal bed to be integrated in a medium flow of the first medium through the exhaust air purification device. Rather, it can be provided that a part of the exhaust air flow removed from the exhaust air purification device and the auxiliary container is supplied, in which the heat bed is arranged. Since the additional container is arbitrarily positioned, the heat exchanger can also be arranged away from the exhaust air purification device. All that is required is a fluid connection between the additional tank and the exhaust air purification device.
- the second medium is air, water or oil.
- the heat exchanger is used in the heat bed for the evaporation of a medium.

- the figure shows a heat bed 1 of a regenerative exhaust air purification device, not shown.
- the thermal bed 1 is composed of a plurality of moldings 2, which are here designed as ceramic shaped bricks 3, in particular as honeycomb bricks. Shown is a horizontal cross-section of the heat bed 1, at a height at which the molded blocks 3 of a vertical plane abut on shaped blocks 3 of a further vertical plane. At this point, the shaped blocks 3 each form two spacing elements 4, in this case feet 5, from. These vertically spaced superimposed shape stones 3 to each other, so that an open-edged recess 6 is present.
- the recess 6 here forms a heat exchanger tube receiving channel 7.
- One of the shaped blocks 3 shows by way of example that the shaped blocks 3 can have a honeycomb-shaped structure 8, which form flow channels 9 for a first medium.
- the flow channels 9 are separated from each other by flow channel walls 10. These flow channel walls 10 may have a coating which leads to the enlargement of a surface of the flow channel wall 10 and thus serves to improve a heat transfer.
- the flow channels 9 pass through both the recess 6 or the heat exchanger tube receiving channel 7 and the spacer elements 4 and the feet 5. It is preferably provided that in the region of the feet 5 the flow channels 9 of vertically adjacent molded blocks 3 have a direct fluid connection, the Thus, the first medium can flow directly from the flow channel 9 of the first molded block 3 in the flow channel 9 of the second molded block 3.
- heat exchange tubes 11 In the heat exchange tube receiving channels 7 of the molded blocks 3 extend heat exchange tubes 11. These can be rectilinear or but, as shown, curved and / or curved. This is preferably provided in such a way that there is always a sufficient distance to the feet 5. Outside the heat bed, the heat exchanger tubes 11 extending through the heat bath 1 are connected to a further heat exchange tube 12. The heat exchange tubes 11 and 12 form a total heat exchange tube 13. As shown, the heat exchange tubes 11 are arranged parallel to each other. The overall arrangement of flow channels 9 exhibiting molded block 3 and arranged in the heat exchange receiving channels 7 heat exchange tubes 11 forms a heat exchanger 14. With this heat can be transferred from a flowing through the flow channels 9 first medium to a second medium flowing through the heat exchange tubes 11.
- a first medium can flow through the flow channels 9 of the shaped bricks 3.
- This first medium is heated, for example, by a combustion or oxidation process.
- heat is transferred from the hot first medium to the shaped brick 3.
- a second medium flows through the heat exchange tubes 11 and 12, wherein the second medium at a lower temperature level than the first Me- is located.
- heat from the first fluid or the heated molded block 3 is transferred to the heat exchange tubes 11 and thus to the second medium. It may be provided that an outer surface of the heat exchange tubes 11 is in fluid contact with the first medium flowing through the flow channels 9. In this way, a particularly efficient heat transfer is ensured.
- the heat exchange tubes 11 are arranged in a heat exchanger tube receiving channel 7, which is not in fluid communication with the flow channels 9. In this case, a heating of the second medium takes place via heat conduction of the molded block 3 or of the heat exchange tube 11.
- the first and second medium do not flow through the shaped brick 3 or the heat exchange tubes 11 at the same time.
- the molded block is preferably used in such a way that initially the first medium flows through the flow channels 9 and thus heats the shaped brick 3. If the shaped brick 3 has reached a certain temperature level, the flow of the first medium is interrupted and the second medium is passed through the heat exchange tubes 11. As described above, the second fluid can now heat up by heat conduction of the heated molded block 3 on the heat exchange tube 11 and thus the second fluid. In this case, the operation of the heat exchanger 14 is not stationary, that is, the heat-bed cools down as heat is transferred to the second medium.
