The utility model discloses an automatic circulating preparation system for desulfurization slurry. The method mainly comprises the following steps of: conveying slurry into a pre-spraying tank by a thick slurry preparation tank through a slurry supply pump; a PH sensor is arranged in the pre-spraying pool; the slurry supply pump is also controlled by the control system in a linkage manner; the PHsensor is provided with a lifting device and a flushing device; an aeration device driven by a fan is arranged at the bottom of the pre-spraying pool; wherein the pre-spraying pool is connected withthe desulfurization tower through a pipeline, liquid obtained after reaction of the desulfurization tower is conveyed into the multi-stage sedimentation pool through a pipeline, upper-layer clarifiedliquid of the multi-stage sedimentation pool flows back into the pre-spraying pool through a pipeline, sediments are pumped into the filter press through the diaphragm pump, and filtered liquid produced by the filter press is c
