Problems solved by technology
[0002] The smelting furnaces of various non-ferrous metal smelting industries need to collect and treat the flue gas containing ferrous metals generated during the smelting process before they can be discharged into the atmosphere. The existing problems of various dust collectors are mainly: single-stage dust removal The effect is poor and cannot meet the national emission standards

Embodiment
[0023] Example: In the lead smoke and lead dust purification device of this example, a lead smoke and lead dust collecting cover 2 is set above the lead smelting furnace 1, and a bag filter 3 is connected to the outlet of the collecting cover. The outlet of the Venturi 6 is connected with a pipe 5 provided with an induced draft fan 4. One end of the Venturi 6 is connected to the outlet of the induced draft fan, and the other end extends into the wet spray atomization swirl plate absorption tower 7. The inner diameter of the Venturi is from the inlet The end is gradually reduced toward the outlet end; the wet spray atomization swirl plate absorption tower is provided with an atomizer 8 in the middle, and an atomization swirl plate 9 is arranged above the atomizer. The top of the tower communicates with the chimney 10 through a pipe.
[0024] In use, the lead smelting furnace 1 passes through the mobile lead smoke and lead dust collection cover 2 to collect the smoke and dust, and ...

The invention discloses a device for purifying lead fume and lead dust in nonferrous metal industry. A lead fume and lead dust collecting cover is arranged above a lead smelting furnace; the outlet of the collecting cover is connected with a bag-type dust collector; the outlet of the bag-type dust collector is connected with a pipeline which is provided with a draught fan; one end of a venturi is connected with the outlet of the draught fan, and the other end of the venturi extends into a wet jet atomization rotating-stream tray absorption tower; the inner diameter of the venturi gradually decreases from an inlet end to an outlet end; an atomizer is arranged at the middle part in the wet jet atomization rotating-stream tray absorption tower; an atomization rotating-stream tray is arranged above the atomizer; and the top of the absorption tower is communicated with a chimney through the pipeline. The fume treated by the device disclosed by the invention can reach and is further lower than the national discharge requirements, and is discharged to the atmosphere from the chimney.
Description
Technical field: [0001] The invention relates to a lead smoke and lead dust purification device in the non-ferrous metal industry. Background technique: [0002] The smelting furnaces of various non-ferrous metal smelting industries need to collect and process the flue gas containing non-ferrous metals produced during the smelting process before they can be discharged to the atmosphere. The main problems with the existing multiple dust collectors are: single-stage dust removal The effect is poor and cannot meet the national emission standards. The dry dust removal process has poor stability and cannot operate continuously and stably, causing environmental pollution. At the same time, it cannot purify other harmful gases in the flue gas. Summary of the invention: [0003] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide a lead smoke and lead dust purification device in the non-ferrous metal industry. The flue gas treated by...
