Description

Smelting waste gas dust collector

Technical Field

The utility model relates to the technical field of waste gas dust removal, in particular to a smelting waste gas dust removal device.

Background

At present, similar process lines in China are generally used for dedusting in two ways: firstly, the temperature of the dust-containing flue gas is reduced through direct or indirect heat exchange, then the dust is filtered and collected through a bag-type dust remover, and finally the dust is concentrated and discharged through a chimney. And secondly, cooling the dust-containing flue gas by a water film deduster, dedusting, and discharging the dust through a chimney. The second dust removal mode is greatly affected by the water solubility of the dust. When the solid particles in the flue gas are aluminum dust with poor water solubility, the second dust removing mode is not applicable.
