METHOD OF PROCESSING PLASTICS WASTE, ESPECIALLY POLYOLEFINES AND A DEVICE FOR PROCESSING PLASTICS WASTE, ESPECIALLY POLYOLEFINES

摘要

14 Abstract The invention relates to a method of processing plastics waste, in particular polyolefines and a device for processing plastics waste, in particular polyolefines used especially in the industrial utilization of plastics waste. The method according to the invention consists in that the primarily refined charge after being fed into the reactor /6/ is fluidized and cracked during forced progressive-rotational movement coinciding with heating, continuously guiding out the final gas-steam fraction to cool and periodically guiding out the impurities of the process from the reactor /6/ and charge transport routes /4/ to the waste tank /22/. The device according to the invention has a rotational reactor /6/ with guiding elements inside it /14,15, 24/, surrounded by a heating medium flowing in the ducts /18/. The control valve /9/ at the outlet of the reactor /6/ divides the stream of the gas-steam fraction into the stream flowing indirectly through the duct /3/ and a receiving collector /18/ and a stream flowing directly to the system of coolers /10/. The device has a bi-directional worm conveyor /4/ in the duct /3/ which is connected to the feeding duct /1/ by a worm feeder /2/ and the waste tank /22/ by the lock /23/.
