Concise device of useless plastics recycling

The utility model relates to a concise device of useless plastics recycling belongs to the chemical industry equipment field, including reaction unit, one -level dust collector and second grade dust collector, reaction unit includes that the bottom is the tubular reactor of back taper, pyrolysis furnace, dual -gate valve, vacuum pump, gas collection room, first manometer, first solenoid valve and second solenoid valve. Make pressure differential through vacuum pump and air compressor between tubular reactor and the pyrolysis furnace, impress in the pyrolysis furnace this method easy operation, work efficiency height with melting dress waste plastics among the tubular reactor, and reaction unit is in closed state all the time in serialization production, avoid harmful gas outwards to discharge, useful environmental protection. The various waste gas that collected the gas collection room, centralized processing, labour saving and time saving, have keep in, the cushioning effect, reduce the potential safety hazard. Remove after the dereaction dust impurity in the gas through one -level dust collector and second grade dust collector, dust removal effect is high.
