Abstract:
Provided is a high efficient desulfurization-regeneration system using a suspension bed, comprising a suspension bed reactor, a gas liquid separation tank, a flash evaporation tank and an oxidation regeneration tank that are connected in sequence, and a fixed bed reactor connected to the exhaust port of the gas liquid separation tank. The system adopts suspension bed to reduce the sulfur content in the hydrogen sulfide containing gas from 2.4-140 g/Nm 3  to 50 ppm or less, and further reduce the sulfur content to less than 10 ppm in conjunction with a fixed bed. High efficient desulfurization is achieved by combining the crude desulfurization of the suspension bed with fine desulfurization of the fixed bed connected in series. The spent desulfurizer can be regenerated by reacting an oxygen-containing gas with the rich solution, and the barren solution obtained by the regeneration may be recycled for being used as the desulfurization slurry, without generating secondary pollution. Therefore, the 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.

Claim (Index 9):
The high efficient desulfurization-regeneration system of  claim 1 , wherein the flash evaporation tank has a pressure drop of 0.1-0.4 MPa.
