The development and applications of the dust and rhenium recovery integrated device of calcination exhaust of molybdenum concentrate which contain rhenium

摘要

A device, was used to recover dust and rhenium from molybdenum concentrate roasting exhaust gas, was developed. The device combine the self swash dust catcher and spherical tray tower technology: the self-swash dust catcher was used to recover dust and rhenium; spherical tray tower was used to further dust and rhenium recovery and its application to engineering in practice. This was the first successful such devices used to recover dust and rhenium integration from calcination exhaust of molybdenum concentrate which contain rhenium in production practice. Through production practice, proved that the device is feasible, with high efficiency. And it has the advantages of simple structure, convenient operation, low cost and low energy consumption etc.. In addition, the dust removing system can also be used to the wet dust collector in the filed of metallurgical, mining, chemical and building.
