Study Analysis on Purification of Alumina Electrolytic Flue Gas by Bag Filter

摘要

To improve the shortcoming in bag filter design in China (mainly used in purification of HF in alumina electrolytic flue gas), necessity of basic theoretical study on bag-filter used in purification of alumina electrolytic flue gas is analyzed. Four study aspects are proposed，which includs flow field optimization, influences of bag length and process parameter on forming dust layer, properties of the dust layer adsorbing hydrogen. Some primary study is done. This will provide a reference for engineering design and process operation.
