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 11):
A high efficient desulfurization-regeneration system using a suspension bed, comprising:\n a suspension bed reactor, provided with a feed inlet at bottom thereof and a discharge outlet at top thereof; a gas liquid separation tank, in connection with the discharge outlet of the suspension bed reactor, and provided with a rich solution outlet at bottom thereof and an exhaust port at top thereof; a fixed bed reactor, in connection with the exhaust port of the gas liquid separation tank, and provided with a purified gas outlet at the top thereof; a flash evaporation tank, in connection with the rich solution outlet of the gas liquid separation tank, and provided with a saturated liquid outlet at bottom thereof; and an oxidation regeneration tank, in connection with the saturated liquid outlet of the flash evaporation tank, and provided with a barren solution outlet arranged at bottom thereof and in connection with the feed inlet of the suspension bed reactor.
