The invention provides a method for the normal pressure continuous desulfurization of rubber, which comprises the steps of: crushing rubber, then adding softening agent and activating agent into the crushed rubber power, evenly mixing the agents with the rubber powder, and desulfurizing the evenly mixed material, wherein the desulfurization comprises the following step that: the material is continuously fed, via a fluidized bed, into a desulfurization pipeline which is equidistantly divided into five sections with each being externally heated, temperature of the five sections of the pipeline is the same, but temperature difference between the sections of the pipeline is present, the heating temperature of the sections of the pipeline in descending order is from 280 DEG C to 240 DEG C in the flowing direction of the material, the interior of the desulfurization pipeline is at normal pressure, the length of each section of the desulfurization pipeline is from 14 to 17 meters, and the flowing time of the material in the entire desulfurization pipeline is from 15 to 20 minutes. The method for the normal pressure continuous desulfurization of rubber according to the invention has the advantages of: good safety, environmental protection, energy saving, stable product performance and high efficiency.
