Abstract

The invention discloses a waste heat recovery system for prebaked anode production and a use method thereof, relates to the technical field of waste heat recovery equipment, and aims to solve the existing problem of how to improve the recovery effect under the premise of waste heat recovery and environmental protection. A soot separator is arranged below one side of the pot calciner, and a flue gas heat exchange pipe is arranged above one side of the soot separator, and a steam boiler is welded and fixed on the upper end of the flue gas heat exchange pipe, and the Heat exchange fins are installed inside the flue gas heat exchange pipe, and the upper end of the heat exchange fins extends to the inside of the steam boiler. An overheating box is installed on one side of the upper end of the steam boiler, and a steam turbine is installed on one side of the overheating box. And the overheating box and the steam turbine are sealed and fixed through pipelines, a generator is installed at the output end of the steam turbine, a water storage tank is arranged under the generator, a deaerator is installed on one side of the water storage tank, and a deaerator is installed on one side of the water storage tank. The other side is provided with a purification tower.

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 ...
