BOTTOM ASPIRATION PURIFICATION SYSTEM

摘要

Disclosed is a bottom aspiration purification system, formed by the following structure: a dust remover, the bottom of which is communicated with a front collection pipe of the dust remover through an air-intake pipe of the dust remover; a reactor, which is arranged at the air-intake pipe of the dust remover; an alumina distributing device, which is arranged between the reactor and a fresh alumina storage cabin and communicated with the reactor through a distributing chute; an alumina feeding device, which is arranged between the alumina distributing device and the fresh alumina storage cabin; a return feeding tube, which is arranged at the lower part of the dust remover. The alumina in the return feeding tube is transferred to a material lifting device through a return chute and then transferred to a fluorinated alumina cabin. The upper part of the dust remover is communicated with an export collection pipe of the dust remover through an export pipe of the dust remover. The export collection pipe of the dust remover is communicated with a chimney through a fan. The system can improve the efficiency and maintenance convenience, reduce the energy consumption of the system and increase the stability of the system.
