Feedstock recycling apparatus from polyester wastes

摘要

The present invention relates to a process for decomposing polyester wastes and an apparatus therefor, and relates to a process for decomposing polyester wastes by using polyethylene terephthalate (DMT) and ethylene glycol (EG) The present invention relates to a regenerating process and a device therefor. The melter is equipped with a conveying means composed of electric or manual screws and check valves which are separated into several separate melting chambers for the continuous operation and are transported to the stepwise separated melting chamber and recover EG which is easy to evaporate in the melting process And a high pressure pump capable of introducing the final reactant of the melter into the first reactor, thereby improving the overall process time, the reaction time and the yield of the product to the first reactor in the melting machine The first reactor is stopped for stopping the first reactor and the energy consumed by the melting machine is saved, thereby increasing the overall reaction rate and reducing the reaction time, thereby achieving economical operation.
