A desulfurization and dust removal process for ore smelting

Abstract

The invention provides an ore smelting desulfurization and dust removal process, comprising a combustion furnace, a dust removal mechanism, a desulfurization mechanism and an adsorption mechanism which are sequentially communicated with one another, the dust removal mechanism comprises a spray tower I and a spray tower II, the lower part of the combustion furnace is connected with smelting waste gas through a pipeline, the upper part is communicated with the spray tower I through the pipeline, the outer side wall of the spray tower II is provided with a strip-shaped cavity, the spray tower I is communicated with the strip-shaped cavity through the pipeline, the desulfurization mechanism is internally and rotatably provided with a shaft tube, a lower end of the shaft tube is communicated with a lower side wall of the spray tower II, the side walls of the desulfurization mechanism is provided with a plurality of vents communicated with an exhaust through pipe, and the exhaust end of theexhaust through pipe is communicated with the upper side wall of the adsorption mechanism; the process improves the process of dust removal and desulfurization of the smelting waste gas through reasonable process improvement and equipment optimization; the dust removal effect can achieve 99.5% or above, and the desulfurization effect can reach 95.7% or above, and the comprehensive benefit is strong, which is worth promoting.

Description

technical field [0001] The invention relates to a desulfurization and dust removal process, in particular to a desulfurization and dust removal process for ore smelting. Background technique [0002] Ore refers to mineral aggregates from which useful components can be extracted or which have certain usable properties, and can be divided into metallic minerals and non-metallic minerals. The unit content of useful components in an ore is called ore grade. Precious metal ores such as gold and platinum are expressed in grams per ton, and other ores are usually expressed in percentages. Smelting is a refining technology, which refers to the extraction of metals from ores by means of roasting, smelting, electrolysis and the use of chemicals; reducing impurities contained in metals or increasing certain components in metals to produce the required metals . A large amount of waste slag will be produced during the smelting process, mainly referring to blast furnace slag and steel s...

Problems solved by technology

[0003] The waste slag smelting furnace will produce a large amount of smoke and dust during the production process. The smoke and dust components are complex, not only containing flammable single crystal substances, but also containing a large number of acidic compounds, which require reasonable purification treatment before they can be discharged into the atmosphere. There are still many deficiencies in the process, such as: large equipment volume, high cost, poor dust removal effect, low desulfurization efficiency, etc. It is necessary to further improve the desulfurization and dust removal process, involving more efficient and economical desulfurization and dust removal equipment
