Returned alumina conveying distribution structure

Abstract

The invention relates to an alumina distribution structure, especially to a returned alumina conveying distribution structure in an electrolytic flue gas purification system. The returned alumina conveying distribution structure comprises returning chutes which are connected with material lifting devices. A connection chute or a steering gear is disposed between the returning chutes. Impurity removing boxes are disposed between the returning chutes and the material lifting devices. The invention has the following advantages and effects: by changing the returned alumina conveying distribution structure in the electrolytic flue gas purification system, the connection chute or the steering gear is disposed between the returning chutes, so as to make the alumina lifting devices to alternate with each other and accomplish continuous and stable operation of the returned alumina conveying system; the impurity removing box is used to remove impurities in alumina, thus guaranteeing the discharging index of the electrolytic flue gas purification system.

Description

technical field [0001] The invention relates to an alumina arrangement structure, in particular to a transport arrangement structure for returning alumina in an electrolytic flue gas purification system. Background technique [0002] In the electrolytic flue gas purification system, the fluorine-loaded alumina usually comes out of the lower hopper of the dust collector and enters the pneumatic chute. Enter the air lift or pressure tank through the pneumatic chute, and drive the fluorine-loaded alumina into the storage bin through the material lifting device. When the electrolytic production capacity is not large, the purification and dust collectors are generally configured in a single row, and the diameter of the fluorine-loaded alumina storage bin is not too large. At this time, a pneumatic lifting device is often used to lift the material. With the expansion of single-series electrolysis production capacity, the electrolysis flue gas purification system is also expanding...
