Abstract

The invention relates to a purification system, and particularly relates to an electrolysis flue gas dry-purification system. The electrolysis flue gas dry-purification system structurally comprises a dust remover, a dust remover outlet pipeline arranged at the top of the dust remover, a reactor connected with the dust remover and a gathering pipeline connected with the reactor, wherein the bottom of the dust remover is communicated with a fluorine-carrying aluminum oxide storage bin, the reactor is communicated with a fresh aluminum oxide storage bin, and the dust remover outlet pipeline is communicated with a chimney through a main draught fan. The invention has the following advantageous effects: the configuration form of the pipelines is changed to reduce local resistance, thereby reducing the whole on-way resistance of the purification system and saving energy; the purification effect is enhanced; and the advantages of small occupied area, high purification efficiency, low energy consumption, low maintenance workload, high control degree and the like are achieved.

Description

[0001] This application is the application number 2009102198251, the application date on November 12, 2009, and the invention and creation name of the electrolytic flue gas drying method. Technical field [0002] The present invention involves a purification system, especially for an electrolytic dried purification system, which is mainly used in the electrolytic flue gas drying workshop in the electrolytic aluminum industry. Background technique [0003] In the electrolytic aluminum industry, the aluminum electrolytic process is based on alumina melody as an electrolyte, carbon material is used as electrode, and metal aluminum with liquid is produced on the cathode. 2 The anode gas.At the same time, air pollutants, which are mainly hydrogen fluoride, fluoride, dust, etc., these gases and anode gas are collectively referred to as electrolytic flue gas. [0004] The electrolytic smoke permeated inside the electrolytic workshop worsen the labor conditions, which seriously affects th...
