High-temperature material conveying, discharging and dust removal system and method

Abstract

The invention discloses a high-temperature material conveying, discharging and dust removal system and a method. The system is applied to anode baking, comprises a retractable suction feeding pipe, abig material cabin, a cyclone dust remover, an air cooler, a first bag dust remover and a first Roots fan, and further comprises a second bag dust remover and a second Roots fan; the second bag dust remover and the second Roots fan are communicated through a pipeline; the big material cabin comprises a retractable discharging pipe arranged at the bottom; a dustproof cover is arranged outside the retractable discharging pipe; an opening is formed in the dustproof cover; and the opening is communicated with the lower part of the second bag dust remover through a pipeline. According to the high-temperature material conveying, discharging and dust removal system, the double Roots fans and the double bag dust removers are switched so as to finish dust removal in the processes of material conveying and discharging; and the high-temperature material conveying, discharging and dust removal system is a crown block dust removal system integrating dust pretreatment, cooling, tail gas purificationand flexible control, adopts a reasonable working procedure design, is scientific in structure, compact in arrangement, and convenient to operate and maintain, achieves high dust removal efficiency,and fully meets the purification and emission requirements of high-pressure high-temperature high-concentration dust.

Description

Technical field [0001] The invention relates to the technical field of dust removal for tail gas purification treatment, in particular to a high-temperature material conveying, unloading and dust removal system and method. Background technique [0002] The non-ferrous metal industry is an important industry of the national economy and one of the ten major industries approved by the State Council in the revitalization plan. It is also a major emitter of energy consumption and smelting waste gas (CO2, SO2, NO2, CF4, HF, etc.). In order to cope with the urgent task of global warming, my country's non-ferrous metal industry must strengthen the research and development and promotion of energy-saving technology, environmental protection technology, low-carbon economic technology, promote the development of green economy, circular economy, and low-carbon economy, and further promote technological innovation in the non-ferrous metal industry , Vigorously reduce greenhouse gas emissions an...

AI Technical Summary

Problems solved by technology

[0004] In view of the characteristics of the above-mentioned flue gas, most of the crane dust removal equipment is now used to achieve the purpose of dust removal, but this kind of crane dust removal equipment must meet the characteristics of high pressure resistance, effective cooling, multiple dust removal to ensure emission standards, etc., and the crane is a high-altitude equipment that can be used The space is limited, so it is necessary to take into account the design of compact structure, convenient operation and maintenance
