Abstract
Provided is an integrated system for wet desulfurization using a suspension bed and regeneration, comprising a suspension bed reactor, a gas liquid separation tank, a flash evaporation tank and an oxidation regeneration tank that are connected in sequence. The integrated system is adapted to reduce the sulfur content in the hydrogen sulfide containing gas from 2.4-140 g/Nm3 to 50 ppm or less by using a suspension bed, so that the desulfurization efficiency is 98% or more. The present invention is adapted to realize regeneration of a spent desulfurizer by reacting an oxygen-containing gas with the rich solution, and the barren solution may be recycled for being used as the desulfurization slurry, without generating secondary pollution. Therefore, a process using the integrated system is simple and reasonable, with high desulfurization and regeneration efficiency, simple equipment, little occupation of land and low investment, which is very suitable for industrial promotion.
