In the upcoming part, you learn the operating sequence using scrap car tires as an example. The animated graphics below illustrates the operating sequence.
Workers lay whole scrap car tires (without rim) manually into the reaction vessel. In average, one vessel contains 800 kg. Afterwards the cap is put on the vessel and closed tightly. The charged vessel is carried to a waiting room. As far as the recycling plant is located in a clime with cold winters, the waiting room is heated with the warm air from the cooling down.
The charged vessel is put into one oven. The run-in into the oven takes place automatically. When pushing the START button, the process begins.
At first, there is a check-up to make sure that all connections are correct. Then heat is given to the vessel and the pyrolysis process starts. During the process gas occurs and is directly led into the cooling coil. There most of the gas condenses to oil. A daily oil tank collects the oil. When a defined level is reached the oil is pumped into the oil-collection-tank. The residual gas is led through a droplet catcher and then directly to the CHP(s).
The process runs fully automatic and lasts 8 hours.
After a process, the reaction vessel is taken out of the oven and the newly charged one is put into the oven immediately. The finished and still very hot vessel is carried to the cooling down area. There the vessel as well as its contents, BERAHN®-Carbon and steel, cool down to ambient temperature.
Afterwards the vessel is carried to the emptying and separation. The cap is taken off and the content is emptied into the separation. Within the separation the carbon is separated from steel and, if applicable, from textile components. The BERAHN®-Carbon is sacked into big bags. A conveyer leads the steel to a baling press where it is reduced to a handy size. The described activities run automatically. The design of the emptying and separation ensures that no carbon dust can reach the environment.
The empty reaction vessel can now be reloaded.
Because of this operating sequence, we recommend that the number of modules in one production hall should not exceed 30 to guarantee an efficient workflow.
