Beschreibung
Zusammenfassung:	The invention discloses a power generation system using composite waste heat of an aluminum electrolysis bath. The power generation system using the composite waste heat of the aluminum electrolysis bath is composed of the electrolysis bath, a bath wall heat exchanger, a smoke-water heat exchanger and a screw expansion generator set, wherein the electrolysis bath is located below the bath wall heat exchanger and is connected with the smoke-water heat exchanger through a smoke outlet pipe, the smoke-water heat exchanger is connected with the bath wall heat exchanger through a bath wall heat exchanger water inlet pipe, and the bath wall heat exchanger is connected with the screw expansion generator set through a medium-pressure steam pipe. According to the power generation system using the composite waste heat of the aluminum electrolysis bath, smoke waste heat generated in the aluminum electrolysis process and heat lost by the bath shell wall are recovered for power generation, so thatpower consumption during
