A kind of asphalt oxidation treatment process

Abstract

The invention relates to the technical field of asphalt oxidation treatment, in particular to an asphalt oxidation treatment process. The process comprises the following steps: S1, introducing oxidized asphalt into asphalt oxidation equipment; S2, introducing hot air into the asphalt oxidation equipment in S1, and after the asphalt is softened, stirring the asphalt; S3, sealing the interior of theasphalt oxidation equipment in S2, and arranging a pressure valve at the top of the asphalt oxidation equipment; S4, mounting a guide rod at the top of the asphalt oxidation equipment, wherein the lower end of the guide rod is located inside the asphalt oxidation equipment, the upper end of the guide rod is located outside the asphalt oxidation equipment, a baffle is arranged at the upper end ofthe guide rod and the baffle is located at an outlet of the pressure valve in S3; S5, after the asphalt oxidation in S4 is finished, discharging the asphalt from the asphalt oxidation equipment. According to the process, the oxidation treatment of the asphalt is realized by introducing hot air into the asphalt, and the hot air is utilized to agitate and cool the asphalt at the same time, so that the sufficient utilization of energy in the asphalt oxidation process is improved.

Description

technical field [0001] The invention relates to the technical field of asphalt oxidation treatment, in particular to an asphalt oxidation treatment process. Background technique [0002] Oxidation method is one of the main methods of asphalt production. Oxidation method can significantly improve the high temperature performance of asphalt products; in the process of asphalt oxidation reaction, the asphalt oxidation reactor is very critical; the existing asphalt oxidation reactor generally includes The kettle body of the outlet and the discharge port is equipped with a motor-connected agitator driven by a motor and a vent line. [0003] When the asphalt reacts, the flowability is poor. When discharging, the discharge speed is very slow, and some asphalt will adhere to the inner wall of the reactor, causing waste, and it needs to be cleaned later, which is troublesome; the floor space of the mixer The large size makes the operating space for workers smaller during maintenance...
