Abstract

The present invention discloses a blast furnace gas desulfurization device and a method thereof, the device comprises a desulfurization tower, the desulfurization tower is a cavity, and the desulfurization tower sequentially comprises a gas inlet section, a catalysis section and an absorption section from bottom to top; wherein a first hole is formed in the tower wall of the gas inlet section, andthe gas inlet section is communicated with a pipeline for providing blast furnace gas through the first hole; the catalytic section and the absorption section are respectively provided with a liquidspraying pipe; and the absorption section is communicated with a blast furnace gas utilization device through the pipeline. After being subjected to desulfurization treatment, the blast furnace gas isconveyed to a hot blast stove or a heating furnace to be used, so that the requirement of ultralow emission is met, an alkali spraying dechlorination tower can be replaced, and the cost is saved.

Description

technical field [0001] The invention belongs to the technical field of metallurgy and environmental protection, and in particular relates to a blast furnace gas desulfurization device and a method thereof. Background technique [0002] Blast furnace gas is a combustible by-product obtained in the blast furnace ironmaking process, and is currently the main fuel for hot blast stoves and heating furnaces at home and abroad. Generally, after blast furnace gas undergoes dedusting and TRT residual pressure power generation in sequence, most of it is sent to hot blast stoves, heating furnaces, etc. as fuel, and the rest needs to be dechlorinated by an alkali spray tower for downstream applications. [0003] Facing the increasingly severe environmental protection situation, the iron and steel industry promulgated and implemented ultra-low emission standards. At present, the Beijing-Tianjin-Hebei region, especially the Tangshan region, implements ultra-low emission limits, requiring ...
