Title:
FLUIDIZING DISTRIBUTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2009/049486
Kind Code:
A1
Abstract:
A fluidizing distribution apparatus for distributing alumina powder in the
fume-purifying system of the aluminium electrolytic process is disclosed.
The fluidizing distribution apparatus includes a material chamber for accommodating
and distributing material, multiple distributor boxes for respectively receiving
the material from the material chamber and discharging them out, and a gas chamber
for providing the fluidizing air for the material chamber to fluidize the material
in this chamber. Wherein, the material chamber is arranged horizontally or nearly
horizontal, and the material chamber is communicated with the distributor box
through adistributor pipe and a distributor nozzle. By setting a small level
of height difference between the material chamber and the distributor box and
by fluidising the material in the material chamber, the upper surface of the material
in the chamber tends to be horizontal, and the relatively identical condition
for distributing can be obtained. Thus it can effectively distribute the powdery
alumina to multiple spots with better results, and it can improve and ensure the
fume-purifying efficiency in aluminium electrolysis. Furthermore, the apparatus
has lower cost and simple structure, so it is easier to be carried out.
