The invention relates to a desulfurization and
desorption system and a use method. The desulfurization analysis
system comprises a washing module, a desulfurization module and a
desorption module. The washing module comprises a washing
tower and a washing tank, the washing
tower is communicated with the washing tank, and the washing tank is communicated with the washing
tower through a washing
circulating pump. The desulfurization module comprises a desulfurization tower and a rich liquor tank, the desulfurization tower comprises an upper alkali washing layer and a lower desulfurization layer, the desulfurization layer is communicated with the water
scrubber, the desulfurization layer is communicated with the rich liquor tank through a rich liquor pump, the alkali washing layer is communicated with an alkali liquor tank, and the alkali liquor tank is communicated with the alkali washing layer through an alkali liquor pump. The
desorption module comprises a desorption tower and a hot water
reboiler, the rich liquor tank is communicated with the desorption tower through a desorption feeding pump, the desorption tower is communicated with the desulfurization layer through a barren liquor pump, and the hot water
reboiler is arranged at the outer bottom end of the desorption tower and is communicated with the desorption tower through a pipeline. The desorption tower is communicated with a vacuum condensate tank through a
vacuum pump module, and the vacuum condensate tank is communicated with the rich liquor tank through a vacuum
condensate pump. The desulfurization effect is stable, the desulfurization efficiency is high, and the desorption effect is good.
