A wet limestone flue gas desulfurization slurry stabilizer and a method for using the same are disclosed. The stabilizer consists of lime, sodium formate and an antifoaming agent, the components and mass percentages thereof are as follows: lime, 30% to 70%, sodium formate, 15% to 40%, the antifoaming agent, 15% to 40%. The method for using the desulfurization slurry stabilizer comprises: preparing the slurry stabilizer into a homogeneous liquid having a mass concentration of 10% to 30% with water or desulfurization slurry outside a desulfurization tower, and spraying the homogeneous liquid into the absorption area and the reaction area of the desulfurization tower using a pump and a slurry atomizing and spraying device.
