Abstract

The invention relates to a method and device for removing high concentration hydrogen sulfide gas, and provides a method for removing high concentration hydrogen sulfide gas. The method comprises the following steps: simultaneously introducing high concentration hydrogen sulfide gas and a strong alkaline adsorption solution into a one-stage or multi-stage swirl injection adsorber; then delivering the adsorption solution that absorbs hydrogen sulfide in the one-stage or multi-stage swirl injection adsorber to a circulation liquid groove, heating the adsorption solution by a coil pipe of the circulation liquid groove, then pumping the adsorption solution into a desorption reactor by a solution circulation pump; in the desorption reactor, oxidizing the adsorption solution in the presence of a metal ion catalyst to carry out desorption so as to separate simple substance sulfur, recovering the separated sulfur; and delivering the effluent generated in desorption reactions into an adsorption solution regenerator, wherein in the regenerator, polyphenol carries out reactions with oxygen in the air to generate quinone, quinone oxidizes reduced metal ion catalysts in the regenerator to recover the catalysts, the oxidation and desulfurization performance of catalysts is recovered, and the adsorption-desulfurization-regeneration circulation is accomplished. The invention also provided a device for removing high concentration hydrogen sulfide gas.
