<p>A industrialized process and a device for production of gasoline, diesel oil from waste plastics, the waste plastics polyethylene, polypropylene, polystyrene or polyethylene, polystyrene or polypropylene, polystyrene are mixed in proportion and put into a reactor undergoing heating, liquefaction and pyrolyzing, the reactor has a dual-screw stirrer inside and a thermal medium of fusedsalt fluid layer outside, after that, subject the product to visbreaking, the pyrolyzing gas condenses to liquid, then goes through fractionation in fractionating tower; At the same time the melt plastics in the reactor is continuously pumped to solid-liquid separator, the residue, mud in the reactor are separated effectively and discharged from the separator through the screw extruder at the bottom of the solid-liquid separator, the clean melt plastics returns back to the reactor, after all the above steps, vacuum distillation is carried out. This invention doesn't need complex catalytic cracking device, run sequentially with high oil yield, good oil quality and low cost, it resolves the problem in existing production of gasoline, diesel oil from waste plastics, disposes white pollution effectively.</p> |
