Description

technical field [0001] The invention relates to the technical field of smelting flue gas treatment, in particular to a quenching collection and treatment system based on smelting flue gas. Background technique [0002] Smelting is a refining technology, which refers to the extraction of metals from ores by roasting, smelting, electrolysis and the use of chemical agents; reducing impurities contained in metals or increasing certain components in metals to smelt the required metals . In the smelting process of sulfide ore, a large amount of low-concentration sulfur dioxide ring-collected flue gas is generated, which directly enters the environmental protection chimney and is discharged, polluting the surrounding environment. Concentrated sulfur dioxide ring-collected flue gas needs to be treated and discharged. The smelting ring collecting flue gas is mainly produced by the furnace melt discharge port, feeding port, settling electric furnace, depletion electric furnace lower...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a quenching collection and treatment system based on smelting flue gas, which can ensure that the dust in the flue gas can be continuously filtered and processed, and there is no need to remove and clean the filter screen regularly, saving time and effort. Ensure that the flue gas can be cleaned in time, and the filter is not easy to be damaged. While ensuring the filtration efficiency, it can also ensure the filtration strength of the filter, and can ensure that the atomization is more uniform and the concentration is sufficient to absorb sulfur dioxide, which improves the absorption of sulfur dioxide. The ability to make the flue gas meet the emission requirements, can use evaporation to absorb heat to make the flue gas quenched, can better cool the flue gas, and facilitate the flue gas to be discharged, etc., which solves the current problem of vulcanization In the treatment device used for flue gas exhaust from mining and smelting, the dust in the flue gas cannot be continuously filtered and cleaned, and the filter needs to be removed and cleaned regularly, which will not only take time and effort, but also cause a certain delay in the treatment of the flue gas. , in the case of using the filter to filter the flue gas, it will cause the filter to be detached from the filter frame during use. , the direct liquid alkali spray used today has a poor absorption effect on sulfur dioxide flue gas, and cannot make the mist distribution uniform, and cannot guarantee the concentration to meet the requirements, so the absorption capacity of sulfur dioxide is poor, and the flue gas emission cannot meet the requirements. After the absorption of sulfur dioxide, the flue gas cannot be continuously quenched, and the flue gas cannot be guaranteed to be discharged.
