Tail gas treatment device for separating and purifying industrial by-product crude selenium

Abstract

The utility model is suitable for the technical field of crude selenium separation, provides a tail gas treatment device for industrial byproduct crude selenium separation and purification, including tail gas treatment tower, the liquid storage mechanism of setting in tail gas treatment tower one side, with the lye treatment mechanism of liquid storage mechanism intercommunication and is provided in the filter assembly of tail gas treatment tower inside, the tail gas treatment tower includes the tower body, the lye treatment mechanism includes the water inlet pipe, first communication pipe and second communication pipe respectively with water inlet pipe intercommunication and is provided the spray pipe of penetrating tail gas treatment tower, install on the spray pipe and have shower nozzle. The device solves the problem that heavy metals and insoluble impurities in flue gas will be precipitated with crude selenium synchronously, resulting in the prepared crude selenium containing heavy metals and other impurities, achieves the effect of removing heavy metal impurities and other insoluble impurities in the roasting flue gas in turn, avoiding the subsequent reaction purification to obtain the industrial byproduct crude selenium containing heavy metals and insoluble impurities which are not easy to separate.
