Definitions
- the invention relates to a material cooler with sealing of the warmer part exposed to oxygen against the ambient air in the colder part of the material cooler.
- Plants, for example for the production of clinker, are now operated using the so-called oxyfuel process, i.e. ideally in pure oxygen.
- the gas at the end of the process is ideally carbon dioxide (with water vapor, which can be separated very easily and thus does not reduce the carbon dioxide concentration at the inlet of a downstream carbon dioxide separation device.
- carbon dioxide can be separated out in a simple manner and thus emissions can be avoided.
- this eliminates the need for complex separation, particularly of nitrogen.
- any source of secondary air i.e. the possibility of ambient air entering the system, should be avoided as far as possible.
- a common separation point between the oxygen-containing area and the ambient air is usually found in the material cooler, where cooling takes place at least at the end with ambient air.
- a method for cooling granular solid material is known from US 8 850 831 B2. From DE 21 58 317 A1 a burning device for burning ore pellets and similar bodies is known.
- separating or baffles are usually used in the material cooler to minimize the gas flows between the different areas. These measures take effect above the material bed and thus reduce mixing. However, these measures have no effect within the material bed, where gas mixing can occur. However, this still leads to mixing and thus to the loss of valuable oxygen and the ingress of nitrogen into the interior. Furthermore, such static devices show wear.
- the object of the invention is to minimize the entry of secondary air into the system via the material cooler.
- the material cooler according to the invention serves to cool a thermally treated material, in particular a bulk material, for example a clinker.
- the actual thermal treatment process is preferably carried out according to the oxyfuel process, i.e. in an oxygen-rich atmosphere.
- the material cooler has a support surface for the material to be cooled.
- the material to be cooled moves through the material cooler on the support surface. This can be done actively by a conveyor element or passively, for example by an inclined arrangement.
- the material cooler has an application side for introducing hot material onto the support surface and a discharge side for discharging the cooled material.
- the material cooler has at least a first cooling zone and a second cooling zone. The first cooling zone is adjacent to the discharge side. The cooled material is thus discharged from the first cooling zone.
- the first cooling zone has a gas supply.
- ambient air is supplied via the gas supply in order to cool the material so that it can be handled after removal from the material cooler.
- a gas can also be supplied via the gas supply, for example from a circuit.
- the gas supplied via the gas supply usually has a disruptive gas component, in particular nitrogen.
- the second cooling zone is adjacent to the first cooling zone. The second cooling zone is thus arranged along the material flow in front of the first cooling zone.
- the second cooling zone has a first water supply for water at more than 100 °C.
- the first water supply is arranged below the support surface or in the material layer arranged on the support surface. This serves to create a water vapor barrier layer in the material layer.
- the first water supply can be designed for liquid, hot water under pressure or for water vapor.
- a supply above 100 °C is effective in order to prevent condensation in the material.
- the materials to be cooled, such as clinker can react with water, so moistening must be avoided. This is necessary, for example in the case of clinker, in order to prevent a subsequent and unwanted reaction when the product is stored.
- the water is preferably supplied between 100 and 200 °C. The optimum here is to choose between utilizing the thermal energy and avoiding condensation.
- Direct cooling of the material layer from above is known, for example by spraying water on.
- the disadvantage is that the gaseous water only forms above the material layer, which is flowed through from below for cooling. Water sprayed from above therefore only has a similar effect to separating or baffle plates. There is also an increased risk of local strong cooling of the material, so that water is absorbed and an unwanted reaction occurs during storage.
- the key to the invention is the application of the water below or within the material layer, whereby a blocking effect is achieved in the material layer and not only above it.
- a key feature is the supply of water from below. Application from above is well known, for example by spraying. In all of these cases, however, a layer of gas always remains within the material, which is not taken up by water vapor. By supplying water from below, the material layer is flowed through, thus creating an efficient gas barrier in this area, even within the material.
- the type of first water supply from below the support surface or in the material layer arranged on the support surface means that a water vapor barrier layer is created within the material layer during operation. Furthermore, the first water supply must be suitable for carrying water vapor or water under pressure and at more than 100 °C. With water vapor, the volume flowing through is significantly larger, with liquid water the pressure is significantly higher. In addition, condensation in the first water supply must be prevented so that no liquid water at less than 100 °C is pumped into the material layer.
- the advantage of using steam is that water can be removed from an exhaust gas stream in a particularly simple manner through condensation. This makes it easier to separate carbon dioxide for use and storage, and thus to achieve climate neutrality overall.
- a water vapor barrier layer is also created above the material layer, so that a separation can also take place here, which can be further supported, for example, by separating sheets and the like, as is known from the prior art.
- What is essential to the invention is that, in addition to this known water vapor barrier layer above the material layer, a water vapor barrier layer in the material layer is automatically generated by the device, and thus an unwanted supply of false air through the material layer can be reliably prevented.
- the material cooler has a third cooling zone.
- the third cooling zone is adjacent to the second cooling zone.
- the third cooling zone is designed for operation with enriched oxygen with a proportion of more than 50 vol. %, preferably more than 90 vol. %, oxygen, i.e. for the so-called oxyfuel process.
- the material cooler is equipped for such operation, as is familiar to the person skilled in the art.
- this concerns the selection of materials, which must be resistant to an oxygen-rich atmosphere, as is familiar to the person skilled in the art.
- it also concerns sealing against the environment, as is familiar to the person skilled in the art, in order to prevent false air and thus the unwanted penetration of nitrogen.
- the device must therefore be designed, within the framework of technical considerations, to be operated with such an atmosphere.
- the oxygen-enriched atmosphere can also only be provided in a device adjacent to the material cooler and thus the second cooling zone, for example a furnace head.
- the sealing takes place directly on the application side of the material cooler.
- the second zone extends over at least 2%, preferably at least 3%, of the total length of the material cooler.
- the second zone extends over at most 50%, preferably at most 35%, further preferably at most 20%, further preferably at most 10%, of the total length of the material cooler.
- the material cooler has a third cooling zone.
- the third cooling zone is adjacent to the second cooling zone.
- the third cooling zone is designed for operation with a mixture of carbon dioxide and oxygen formed, with the sum of oxygen and carbon dioxide being more than 80 vol.%. This also corresponds to the oxyfuel process, with carbon dioxide (mostly from the exhaust gas) being recycled. And so the gas flow is increased in order to replace the nitrogen missing in pure oxygen and thus make the carrying capacity of the gas flow comparable to conventional processes.
- the ratio of oxygen to carbon dioxide can therefore be selected to be 1:5, analogous to the oxygen content in the air, taking other gas components into account. This means that the material cooler is equipped for such operation, as is familiar to the expert.
- the material cooler has a fourth cooling zone.
- the fourth cooling zone is adjacent to the second cooling zone.
- the fourth cooling zone has a carbon dioxide supply.
- the carbon dioxide can be supplied to a calciner, for example, via a carbon dioxide outlet and a tertiary air line.
- the carbon dioxide outlet can be connected to the carbon dioxide supply, i.e. the carbon dioxide can be recirculated.
- the carbon dioxide therefore does not have to be pure carbon dioxide, but can contain other substances, particularly in the case of recirculated carbon dioxide.
- the aim is to achieve a double barrier layer, firstly made of water vapor and secondly of (recirculated) carbon dioxide.
- the device is accordingly designed to be able to handle these atmospheres or to be stable in these atmospheres.
- the material cooler has a fifth cooling zone.
- the fifth cooling zone is adjacent to the fourth cooling zone.
- the fifth cooling zone has a second water supply for water with more than 100 °C.
- the second water supply is arranged below the support surface or in the material layer arranged on the support surface to create a water vapor barrier layer in the material layer.
- the second water supply can be designed for liquid water under pressure or for water vapor.
- a supply above 100 °C is effective in order to prevent condensation in the material. This is necessary, for example in the case of clinker, in order to prevent a subsequent and unwanted reaction when the product is stored.
- the water is preferably supplied between 200 and 400 °C. Since there is another cooling zone, water at a significantly higher temperature can be used here. The above also applies here.
- the second water vapor barrier layer enables secondary air and tertiary air in particular to be kept comparatively clean.
- the device is designed, thanks to its spatial features, to form and support these different zones and thus different atmospheres.
- the material cooler has a seventh cooling zone.
- the seventh cooling zone is adjacent to the fourth cooling zone.
- the seventh cooling zone is designed for operation with enriched oxygen with a proportion of more than 50 vol.%, preferably more than 90 vol.%, oxygen.
- This means that the material cooler is equipped for such operation, as is familiar to the person skilled in the art. For example, this concerns the selection of materials, which must be resistant to an oxygen-rich atmosphere, as is familiar to the person skilled in the art. In addition, it also concerns sealing against the environment, as is familiar to the person skilled in the art, in order to prevent false air and thus the unwanted penetration of nitrogen.
- the device must therefore be designed, within the framework of professional considerations, to be operated with such an atmosphere.
- the material cooler has a sixth cooling zone.
- the sixth cooling zone is adjacent to the fifth cooling zone.
- the sixth cooling zone is designed for operation with enriched oxygen with a proportion of more than 50 vol.%, preferably more than 90 vol.%, oxygen.
- This means that the material cooler is equipped for such an operation, as is familiar to the person skilled in the art. For example, this concerns the selection of materials, which must be resistant to an oxygen-rich atmosphere, as is familiar to the person skilled in the art. In addition, it also concerns sealing against the environment, in order to prevent false air and thus the unwanted ingress of nitrogen. The device must therefore be designed, within the framework of professional considerations, to be operated in such an atmosphere.
- the third cooling zone has a gas outlet.
- the gas outlet is connected to the carbon dioxide supply and/or a calciner, in particular via a tertiary air line.
- a first mechanical gas separation device is arranged between the first cooling zone and the second cooling zone.
- the first mechanical gas separation device is preferably at a sufficient distance from the material on the support surface in order to prevent wear. Additional mechanical gas separation devices can also be arranged analogously between further cooling zones.
- the invention relates to a method for operating a material cooler according to the invention.
- the application atmosphere differs from the discharge atmosphere.
- the discharge atmosphere is preferably ambient air, or is formed from ambient air and preferably differs from the ambient air only in terms of moisture and possibly dust.
- the application atmosphere preferably has a reduced nitrogen content compared to the discharge atmosphere.
- the application atmosphere and the discharge atmosphere are separated by a water vapor barrier layer in the material to be cooled in the second cooling zone.
- the application atmosphere has a higher oxygen content and a lower nitrogen content than the discharge atmosphere.
- the second cooling zone is non-condensing, i.e. at a temperature level of over 100 °C at normal pressure or in accordance with the vapor pressure curve at other pressures.
- the water remains as water vapor in the gas phase and does not condense on the material. This reliably prevents moistening and thus setting during storage.
- FIG. 1 A first example is shown in Fig. 1. It is, for example, a plant for producing clinker from limestone.
- the plant has a preheater 10, a calciner 20, a rotary kiln 30 and a material cooler 40 according to the invention, whereby the material flow from the preheater 10 is led via the calciner 20 and the rotary kiln 30 into the material cooler 40.
- the gas flow goes from the rotary kiln 30 via the calciner 20 into the preheater.
- the rotary kiln 30, calciner 20 and preheater 10 are designed for operation according to the oxyfuel process, i.e. with (technically) pure oxygen, and are operated in this way.
- the material cooler has a first cooling zone 41, which is supplied with cool ambient air by a gas supply 51 and thus cools the material, the clinker, to near ambient temperature.
- the material cooler has a second cooling zone 42, into which pressurized water at, for example, 150 °C is supplied from below via a first water supply 52, thereby creating a safe, simple and wear-free separation between the oxygen-rich area and the ambient air.
- the first example has a direct supply of oxygen into the rotary kiln 30, for example via the kiln head. Since combustion in (technically) pure oxygen is very hot, preheating of the oxygen is not necessary.
- Fig. 2 shows a second example where the oxygen is not fed directly into the rotary kiln 30, as in the first example, but is first fed via an oxygen supply 53 into a third cooling zone 43 and is preheated there and fed preheated from the third cooling zone 43 into the rotary kiln.
- the third cooling zone 43 is arranged directly adjacent to the second cooling zone 42.
- Fig. 3 shows a third example in which a fourth cooling zone 44 is arranged adjacent to the second cooling zone 42. Carbon dioxide is supplied to the fourth cooling zone 44 via a carbon dioxide supply 54. In the third example, as in the first example, the oxygen is also supplied directly to the rotary kiln 30.
- the fourth example shown in Fig. 4 differs from the third example in that a fifth cooling zone 45 with a second water supply 55 is arranged adjacent to the fourth cooling zone 44. This prevents the carbon dioxide from the fourth cooling zone 44 from entering the rotary kiln 30. Instead, the carbon dioxide is fed directly to the calciner 20 via a tertiary air line in order to generate a larger volume flow there and thus increase the load-bearing capacity for the material in the gas flow.
- the fifth example shown in Fig. 5 differs from the third example in that a seventh cooling zone 47 is arranged adjacent to the fourth cooling zone 44, with (technically) pure oxygen being supplied to the seventh cooling zone 47 via an oxygen supply 57, where it is preheated and then supplied to the rotary kiln 30. The carbon dioxide from the fourth cooling zone 44 is supplied to the calciner 20 via a tertiary air line, as in the fourth example.
- Fig. 6 shows a sixth example, which differs from the fourth example in that the material cooler 40 has a sixth cooling zone 46 adjacent to the fifth cooling zone 45, wherein (technically) pure oxygen is supplied to the sixth cooling zone 46 via an oxygen supply 56, preheated there and then supplied to the rotary kiln 30.
