Abstract

The invention discloses a waste heat recovery system for prebaked anode production, and a using method thereof, and relates to the technical field of waste heat recovery equipment. The recovery effectis improved on the premise that the existing waste heat recovery is environmentally friendly. A smoke-dust separator is arranged below one side of a pot calciner, and a smoke heat exchange pipeline is arranged above one side of the smoke-dust separator; a steam boiler is fixedly welded at the upper end of the smoke heat exchange pipeline, and heat exchange fins are installed in the smoke heat exchange pipeline, and the upper ends of the heat exchange fins extend into the steam boiler; a superheater header is installed on one side of the upper end of the steam boiler, and a steam turbine is arranged on one side of the superheater header; the superheater header and the steam turbine are fixed through a pipeline hermetically, and a generator is installed at the output end of the steam turbine; a water storage tank is arranged below the generator, and a deaerator is installed on one side of the water storage tank; and a purification tower is arranged on the other side of the water storagetank.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery equipment, in particular to a waste heat recovery system for prebaked anode production and a use method thereof. Background technique [0002] The production of prebaked anodes is based on petroleum coke and coal tar pitch, which are less ash carbon materials, to produce prebaked anodes for aluminum electrolytic cells. After entering the factory, the raw materials petroleum coke and coal tar pitch are stored in the raw material warehouse and the pitch warehouse respectively. Petroleum coke from different origins is grabbed by grab bucket crane according to the specified raw material ratio, mixed and batched in the batching warehouse, crushed by the crusher, and then sent to the pot calciner for high-temperature calcination. The calcined coke is crushed and processed twice. Sieve to get three qualified particle materials, which are stored in each silo. Part of the calcined coke enters ...
