Description
[0001] 18-09- 2024- 393E3101- Hau Po s - 0008 PCT / DE2024 / 000072 WO 26 and process use [ Worldwide environmental impacts Landfilling of More and more chemicals and heavy metals The proper landfilling of certain areas in the groundwater can also have an impact on the environment, as separation and reuse of applications.[ The invention relates to a process for the separation of metals from waste incineration plants. [ The separation of metals from waste incineration plants essentially involves the use of a slag treatment plant which normally has a size of > 300 mm and which is then used to recover magnetically conductive materials. These can be used in accordance with the plant arrangement, however they must be independent of one another before the separation of the slag can begin. The separation of metals from waste incineration plants involves the use of a slag treatment plant which normally has a size of > 300 mm and which is then used to recover magnetically conductive materials.According to known existing processes certain quantities are to be separated economically [ However, there are still hurdles to be overcome Reuse as in cement production Ceramic products Due to heavy metals and aluminium minerals 18-0:_Ei-2024-38363101-1-lauP t 0010 PCT / DE2024 / 000072 WO 26 level Due to heavy metals Aluminium particles can lead to environmental pollution [ With the increasing landfill volumes and efforts to reuse of materials in the fight against climate change, use after separation of materials as well as [ The landfill can also be economical as depending on the country and through reuse, landfill costs can be high.This means that the separation of the slag and the bottom ash can be increased and improved, and the end products can be recycled. [ The object of the invention is to treat the bottom ash in a waste incineration plant and the bottom ash treatment plant, which has an input, output and output and a method for treating slag incineration plants, 18-09-2024-393i73101-HauP Pas t 0011 PCT / DE2024 / 000072 WO 26 the slag can be subjected to several cycles. [ Devices and methods are therefore concerned with achieving high levels of [ The object is to treat the bottom ash and the bottom ash in a waste incineration plant and in order to do so without having to.[ The basic task the features [ Further developments Subject [ The method according to the invention could Preferably, the batch is preferably taken twice in a material treatment plant and two times in front of it. The return is This will be necessary in order to If you have to take slag in the - could at some point be and back towards the effect If there is still slag from the system, at some point the maximum amount, and If preferably two large components in the As a rule, the throughput can be increased which leads to a bottleneck [ The normally a combination of the bucket elevators [ In the material removal outlet. The material removal outlet can be the system via the system. It If the slag is then removed from the system.The material removal outlet can be a folding box with two outlets [ In order to be able to select between the outlet and one or more of the eddy current separators, the lines are brought together in the 18-09-2024-393S3101-HauP po t-0013 PCT / DE2024 / 000072 WO 26. [ The and at least preferably an eddy current separator. The basic variants are based on a magnetic drum, number of magnets on the magnetic drum, and whether or not the incoming speed of the conveyor belt is also based on the magnetic drum. The magnetic drum can also be used to separate the magnets from the drum.[ The repulsion property due to a magnetic field is the decisive factor in the separation of metals. The interaction between the material and the geometry is crucial. [ The high repulsion and the high trajectory can lead to a weakened trajectory and separation. 18-09-2024-393S3101-1-4auP tPos t-0014 PCT / DE2024 / 000072 WO 26] The size of the repulsion can weaken during the trajectory and the separation can result in a weakened trajectory and thus a more difficult separation. Even in space, when the magnetic field is present, the calculation formula is based on the choice of the [ The rule for calculating the compromise is: There will be more eddy current separators due to the presence of fewer eddy current separators. In order to have a higher eddy current arrangement, one or more eddy current separators can have higher eddy currents, and thus more difficult separation can occur. By increasing the number of separation devices, the result will be a higher eddy current separation.18-09-2024-39363101-HauP Pas t 001S PCT / DE2024 / 000072 26 [ The number of material withdrawals can be increased or decreased before the material is withdrawn or removed from the system. The number of sensor outputs can be increased or decreased before the material is withdrawn or removed from the system. This can be achieved by utilising the new sensor's maximum capacity in the batch process. The number of sensor outputs can be increased or decreased before the material is withdrawn or removed from the system. This will enable the separation of impurities from the before and after cycles and the after each cycle. [In order to separate them from the after each cycle and the after each cycle, and to separate them from the after each cycle, and to achieve a high level of separation after the end of the cycle. 18-09-2024-39363101-HauPt Pas 0016 PCT / DE2024 / 000072 WO 26 This will enable the separation of impurities from the before and after cycles and the after each cycle.This can be done in addition to the processing system and with several magnetic separators. The separation can also be done with a magnetic drum and a magnetic separator between the output and the input. The overall system essentially consists of two components: the magnetic separator and the magnetic separator. The magnetic separator must be installed between the two components and the magnetic separator. The magnetic separator must be installed between the two components and the magnetic separator. The magnetic separator must be installed between the two components and the magnetic separator.In this case the quantity predominant [ the figures and are shown in the further elements It Figure flow diagram device with an extension Figure flow diagram how which eddy current Figure flow diagram on the flow diagram Figure flow diagram how which with a magnetic separator 18-09-2024-3S383101-HauPiPost-0018 PCT / DE2024 / 000072 WO 26 [ In the case of a material treatment plant the flow diagram shows how the material is treated. As soon as the maximum capacity is reached, the 4 is fed via the outlet from the feed silo to the inlet 27, untreated 4 is fed to the outlet and exit 9. The primary return line 9 is used. As soon as the 4 is fed to the feed silo, the slag is conveyed to the new slag 4 from the outlet 29 via the line direction according to the size of the slag. The number of cycles can be changed over.As soon as the maximum amount of slag is removed from the system, a new batch of slag is fed into the feed silo and the system during the cycle to give the cycle [ The flow diagram extension 9 and 20 after the exit which again 20 from before after the The two effects are combined after separation. To the flow diagram after the exit Before cycle 20 can be in order to the cycle [ the flow diagram system and 22 For this purpose, several systems 22 are combined after separation. In this flow diagram 22 after the exit switchover valve [ a the desired number of untreated 4 can be like 4.By expanding the system, the number of incoming slag is increased before the system 23 and the system 24. Afterwards, the system is equipped with a magnetic separator 26 and a magnetic separator 26. The slag is then directed towards the output and the system [General material treatment plant] A material treatment plant can be used with two or more systems, such as a material treatment plant with several slag batches or a magnetic separator 26, which can be used to increase the number of cycles.
