Vertical Vacuum Pyrolysis Cleaning Device

Principle:
Vacuum Pyrolysis Cleaning device is designed specially for cleaning polymers from a variety of metal components. The parts to be cleaned are heated in a chamber where the polymer melts and drains into the bottom collector. Remaining polymer is vaporized and then water scrubbed in a secondary scrubber where condensates are collected and rush out with water. Since cleaning takes place under vacuum, combustion does not occur. The parts are protected from excessive or localized high temperatures. The whole process has no pollution.
Cleaning stage:
A.Melting stage
During heating up(150℃),the PET materials adhering to the spin packs（or Filter） to be cleaned first all become liquid but do not decompose thermally.
The melting plastic flows via a discharge trough into the cooler melt container,where it can cool down and then be removed for the further porcessing stage.
B.Pyrolysis stage
On reaching the decomposition temperature of the respective polymer,the heat output is regulated automatically in the process chamber in such a way that the best possible conversion is guaranteed in the catalytic converter.
C.Oxidation stage
The oxygen is added to the process chamber to oxidise any remaining residues of the organic products of decomposition.Any remaining inorganic residues on the cleaned components can easily be removed mechanically,
D.Cooling stage
The process chamber heating is switched off during the cooling stage。
