Prebaked anode roasting furnace flue gas purification device

Abstract

The invention provides a prebaked anode roasting furnace flue gas purification device, and belongs to the technical field of roasting furnace flue gas purification. The prebaked anode roasting furnaceflue gas purification device comprises a purification box body and a fan arranged at the bottom of the outer side of the purification box body, and the output end of the fan is communicated with thepurification box body through an air pipe. The embodiment of the invention has the advantages of good flue gas purification effect and high purification efficiency; adriving assembly is adopted to drive a pressing plate to rotate along the side wall of afilter screen; ascraping layer is used for scraping dust particles attached to the side wall of the filter screen; the pressing plate and the vertical central axis of aconical supporting plate are of a spatial crossing structure, the pressing plate and the scraping layer are obliquely attached to the side wall of the filter screen; when the driving assembly drives the pressing plate to rotate, dust particles attached to the side wall of the filter screen can be scraped downwards, so that the dust particles are gathered in a gapformed by theconical supporting plate and the purification box body, and therefore the situation that the dust particles are continuously attached to the side wall of the filter screen, the filter screen is blocked, and the follow-up flue gas purification effect is affected is prevented.

Description

technical field [0001] The invention belongs to the technical field of flue gas purification of roasting furnaces, in particular to a flue gas purification device for prebaked anode roasting furnaces. Background technique [0002] Roasting is the process of completing a certain chemical reaction below the melting temperature of the material, which is an integral part of the charge preparation. Most of the materials always exist in solid state, so the roasting temperature is limited to ensure that the materials do not melt significantly. Obviously, the roasting reaction is mainly solid-gas reaction, and sometimes there are solid-solid, solid-liquid and gas-liquid interactions or interactions. Roasting mostly prepares for the main smelting operations such as smelting or leaching in the next step, so it is often a charge preparation process in the smelting process, but sometimes it can also be used as a enrichment, impurity removal, metal powder preparation or refining process...

AI Technical Summary

Problems solved by technology

[0003] The roasting furnace tends to produce a large amount of flue gas when it is working, and the flue gas contains a large amount of incompletely roasted powder. In the prior art, the treatment of the flue gas powder is mostly to make the flue gas pass through the filter screen, and use the filter screen to process the powder. However, after long-term use of the filter, a large amount of powder tends to adhere to it, causing the blockage of the filter, which in turn affects the continued filtration of the subsequent flue gas. Currently, most of the cleaning of the filter relies on Manually, there are defects of poor cleaning effect and time-consuming and labor-intensive
