Definitions

  • the present invention relates to a system for producing building blocks from ceramic material with a device for processing the ceramic material by means of water and steam, a device for pressing the building blocks, a device for drying the building blocks and a device for burning the dried building blocks.
  • Another emission source is that after the clay material has been compressed into building blocks, a large part of the moisture is removed from it in a device provided for this purpose, in particular in a tunnel dryer. With the water vapor which is thereby produced, however, portions of the ceramic material are also removed which are not known in their composition and in their extent and which have not been taken into account to date. Subsequently, the building blocks are fired in a device provided for this purpose, in particular in a tunnel kiln, and are guided in countercurrent to the fuel gases. The emission emitted by the tunnel furnace therefore contains combustion residues on the one hand and, on the other hand, parts of ceramic material. In order to avoid damage to the environment, it is known to clean the emissions emitted by the tunnel furnace using filter systems before they are discharged via a chimney.
  • the present invention is based on the knowledge that there is a need not only to clean the emissions released by the tunnel kiln before they are released into the atmosphere, but that this requirement also applies to the emissions released by the device for drying the building blocks, it is also taken into account that the processing of the ceramic material requires water which has so far been taken from external water sources in such systems.
  • the object of the present invention is therefore to provide a plant for the production of building blocks from ceramic material, from which less harmful emissions are emitted to the environment than is the case with known plants, and this also for the processing of the ceramic material required water is obtained in the system itself.
  • a device in which the emissions emitted by the drying device are condensed. Furthermore, a device is preferably provided in which the water obtained by condensation is treated. In particular, the water vapor emitted by the drying device is condensed in a heat exchanger.
  • the water obtained by condensation can be fed to the device for processing the ceramic material. Furthermore, the water obtained by the condensation can be fed to a treatment device, from which it is released to a steam boiler for generating the water vapor or to a sewer.
  • the treatment device can be used for mechanical and chemical cleaning of the water obtained by condensation.
  • Fig. 1 such a system, in a schematic representation
  • Fig. 2 shows a part of this system, on an enlarged scale compared to Fig. 1.
  • a conveyor e.g. a wheel loader 1
  • ceramic material such as clay
  • a further conveyor such as a box feeder 2
  • a pan mill 3 is fed.
  • the clay material is plasticized and homogenized.
  • the material discharged from the pan mill 3 is subsequently fed to a first rolling mill 6 and then to a second rolling mill 7, in which it is subjected to coarse grinding and fine grinding.
  • the ground material is fed from the second rolling mill 7 by means of a conveyor, in particular by means of a conveyor belt 8, to an intermediate storage 10, in which it is stored for one to two weeks.
  • an intermediate storage 10 in which it is stored for one to two weeks.
  • the clay particles are disrupted for the further processing of the material.
  • the clay material which has been digested as a result of the storage is removed from the intermediate storage 10 by means of an excavator 11 and then fed to a twin-shaft mixer 12, in which water vapor supplied to it via a line 13 is mixed.
  • the material is delivered from the twin-shaft mixer 12 to a screw press 14, in which a clay strand is produced, which is then divided into individual building blocks 16 by a cutting device 15.
  • the building blocks 16 produced in this way are applied to dryer cars 17 and guided through them through a drying device, in particular a tunnel dryer 18.
  • a drying device in particular a tunnel dryer 18.
  • the saturated water vapor with a temperature of 30 ° C. to 50 ° C. released by the tunnel dryer 18 via an exhaust gas line 19 is fed to a device 20 for processing the water vapor, which is described below with reference to FIG. 2.
  • the building blocks coming out of the tunnel dryer 18 are separated and are subsequently applied to kiln cars 33 by means of a setting machine 32, by means of which they are passed through a tunnel kiln 34.
  • the building blocks are fired in the tunnel furnace 34, being passed in the direction of the arrows A, whereas the flue gases are passed in the counterflow in the direction of the arrow B. After filtering and processing, the flue gases are released into the atmosphere via a chimney 35.
  • the fired building blocks are reloaded onto pallets 37 by means of a gripper 36.
  • the pallets 37 are subsequently moved to a packaging station 38, in which they are wrapped in a film. Using a forklift 39 the pallets 37 are brought to a warehouse 40, from which they are transported by trucks 41.
  • the device 20 shown in FIG. 2 for processing the emissions emitted by the tunnel dryer 18 via line 19 consists of a heat exchanger 22 in which air supplied via a connection 23 is heated and in which the water vapor supplied via line 19 is condensed.
  • the condensed water released by the heat exchanger 22 acting as a condenser is released via a line 24 to a water basin 25.
  • the line 4 goes from the water basin 25 to the pan mill 3.
  • the water required in the pan mill 3 can be removed from the water basin 25, so that no external water source is required for this.
  • water from the water basin 25 is also fed to a treatment device 28, in which the water mixed with portions of the ceramic material is so largely cleaned by mechanical treatment, such as filtering, and chemical treatment, that on the one hand it is supplied via a line 29 a steam boiler 30, in which the steam required in the twin-shaft mixer 12 is generated, and on the other hand can be discharged via a line 31 to a sewer.
  • a treatment device 28 in which the water mixed with portions of the ceramic material is so largely cleaned by mechanical treatment, such as filtering, and chemical treatment, that on the one hand it is supplied via a line 29 a steam boiler 30, in which the steam required in the twin-shaft mixer 12 is generated, and on the other hand can be discharged via a line 31 to a sewer.
  • the condensation of the steam emitted by the drying device 18 and the subsequent treatment of the water obtained in the condenser 22 thus prevent emissions which contain harmful components from being emitted to the environment. This also results in the water that is used on the one hand for processing the clay material in the pan mill and on the other hand for generating the steam required in the twin-shaft mixer in the steam boiler is recovered in the plant, whereby there is no need to supply water from an external water source.
