Abstract

The invention relates to a purification system, in particular to an electrolytic flue gas dry purification system. The system comprises a dust remover, a dust remover outlet pipe, a reactor and a collecting pipe, wherein the dust remover outlet pipe is arranged on the top of the dust remover; the reactor is connected with the dust remover; the collecting pipe is connected with the reactor; the bottom of the dust remover is communicated with a fluorine-carrying alumina storage cabin; the reactor is communicated with a fresh alumina storage cabin; and the dust remover outlet pipe is communicated with a chimney through a main induced draft. The system has the advantages that: local resistance is reduced by varying a pipe configuration mode so as to reduce entire on-way resistance of the purification system and save energy consumption; and the system improves purification effect and has the advantages of small occupied area, high purification efficiency, low energy consumption, small maintenance capacity, high control degree and the like.

Description

technical field [0001] The invention relates to a purification system, in particular to an electrolytic flue gas dry purification system, which is mainly used in electrolytic flue gas dry purification workshops in the electrolytic aluminum industry. Background technique [0002] In the electrolytic aluminum industry, the aluminum electrolysis process uses the alumina melt as the electrolyte and the carbon material as the electrode for electrolysis. Liquid metal aluminum is precipitated on the cathode, and CO is produced on the anode. 2 main anode gas. At the same time, air pollutants such as hydrogen fluoride, fluoride, dust, etc. will be emitted. These gases and anode gas are collectively called electrolysis flue gas. [0003] The electrolysis fume permeating inside the electrolysis workshop deteriorates working conditions and seriously affects the health of production workers. The diffusion of electrolytic flue gas around the factory area will pollute the atmosphere and ...
