Abstract

The invention provides a device capable of conducting dust removal and arsenic recovery on non-ferrous smelting smoke at the same time. The device comprises a fan, a dust removal and arsenic precipitation integrated device and a quenching arsenic recovery device which communicate with one another in sequence, wherein a turntable which is connected with a driving device through a transmission shaftis arranged in the dust removal and arsenic precipitation integrated device, through holes through which the smoke runs are formed in the turntable, intercepting pipes used for adsorbing smoke dust and partition boards used for dividing an arsenic precipitation and removal device into a dust removal region, an arsenic precipitation region, an arsenic removal region and an injection region are arranged on the turntable, the through holes are formed in the upper ends and the lower ends of the dust removal region, the arsenic precipitation region, the arsenic removal region and the injection region respectively, the through hole in the lower end of the dust removal region is connected with the fan, the through hole in the upper end of the dust removal region is connected with the through hole in the upper end of the arsenic precipitation region, the through hole in the lower end of the arsenic precipitation region is connected with a smoke outlet, the arsenic precipitation region is connected with a cooling device, the arsenic removal region is connected with a heating device, and the through hole in the upper end of the arsenic removal region is connected with the quenching arsenicrecovery device. By means of the device capable of conducting dust removal and arsenic recovery on the non-ferrous smelting smoke at the same time, operation of dust removal and arsenic precipitationcan be conducted by one device, and not only is a smoke treatment technology simplified, but also the purity of recovered finished product arsenic can be improved.

Description

technical field [0001] The invention relates to the fields of metallurgy and environmental protection, in particular to a device capable of simultaneously removing dust and collecting arsenic from nonferrous smelting flue gas. Background technique [0002] High-arsenic polymetallic materials are important raw materials for non-ferrous metal smelting. When the mass percentage of arsenic is ≥ 2%, it is called high-arsenic polymetallic materials in the industry. In recent years, with the shortage of resources, comprehensive recovery of high-arsenic and polymetallic materials has become a trend. When treating high-arsenic materials by fire method, the arsenic in the materials mainly exists in the form of free oxides, and a carbonaceous reducing agent is added to the materials. 2 o 5 Revert to As 2 o 3 , arsenate is reduced to arsenite, arsenite is reduced to metal arsenide, and finally As 2 o 3 The gas form is volatile. [0003] There are two methods for arsenic flue gas ...
