Non-ferrous metal smelting kiln tail gas deep purification and white smoke removal treatment system

Abstract

The invention relates to the technical field of kiln tail gas dust removal, in particular to a non-ferrous metal smelting kiln tail gas deep purification and white smoke removal treatment system which comprises a dust removal device shell, flange connectors, a kiln smoke exhaust pipe, a filter, a rotating device, an induced draft fan air inlet pipe, a fixing device, a recycling device and a plugging plate. One end of the dust removal device shell is connected with the kiln smoke exhaust pipe through the corresponding flange connector, the filter is arranged in the dust removal device shell, the rotating device is arranged at one end of the filter, and one end of the rotating device is connected with the induced draft fan air inlet pipe through the corresponding flange connector. One end of the filter is in butt joint with a rubber block on a pressing plate, the filter is pushed to extrude the pressing plate, the pressing plate linearly retreats under the matching action of a guide column and a vertical bearing and compresses a spring until a boss at the other end of the filter is matched with an annular groove, and the filter is clamped between the rotating device and the fixing device under the bounce action of the spring, the fixing device is simple in structure and easy to operate, and workers can replace and maintain the filter conveniently.

Description

technical field [0001] The invention relates to the technical field of tail gas dedusting, in particular to a non-ferrous metal smelting kiln tail gas deep purification and whitening treatment system. Background technique [0002] The non-ferrous metal industry is of great significance to economic development and national defense and military construction. Usually, most of the mineral raw materials and fuels used in non-ferrous metal smelting contain sulfur, arsenic, phosphorus, and fluorine. The exhaust gas contains a large number of complex corrosive components, so it must be treated by a purification system before it can be discharged. [0003] The existing kiln tail gas deep purification and whitening treatment system; the whole system includes kiln, dust removal equipment, induced draft fan, wet desulfurization, condenser, electromagnetic dewhitening device, chimney, etc.; the hot exhaust gas from the kiln first enters the dust removal equipment , sent to the wet desul...

AI Technical Summary

Problems solved by technology

[0003] The existing kiln tail gas deep purification and whitening treatment system; the whole system includes kiln, dust removal equipment, induced draft fan, wet desulfurization, condenser, electromagnetic dewhitening device, chimney, etc.; the hot exhaust gas from the kiln first enters the dust removal equipment , sent to the wet desulfurization tower through the induced draft fan, after dust removal and desulfurization, it enters the condenser, then enters the electromagnetic dewhitening device, and finally the treated gas enters the chimney to meet the standard discharge. Most of the existing dust removal equipment uses cyclone dust collectors and bag dust collectors Although the dust removal effect of the cyclone dust collector is good, it is very troublesome for workers to maintain the cyclone dust collector due to the complex structure. Although the bag filter device is easy to maintain, its service life is too short, so workers need to replace the dust bag frequently. Therefore, the present invention proposes a non-ferrous metal smelting kiln tail gas deep purification and whitening treatment system to solve the above problems
