The invention discloses an anti-coking asphalt oxidation tower. The anti-coking asphalt oxidation tower comprises a tower body, an air inlet distributor, an asphalt distributor, an anti-coking deviceand an oxidized asphalt disperser. The air inlet distributor comprises a transverse air inlet pipe and a vertical air inlet pipe, and a plurality of air outlets are formed in the vertical air inlet pipe and the transverse air inlet pipe. The asphalt distributor is a distribution disc with an arc-shaped upper end surface. The anti-coking device comprises an umbrella cap cover and an anti-coking disc. The oxidized asphalt disperser comprises a plurality of baffles, the joints of the baffles and the tower body are obliquely arranged, dispersion plates are arranged on the two sides of the bafflesrespectively, the free ends of the dispersion plates are obliquely arranged downwards and form trapezoidal structures with the baffles, the baffles on the inner wall of the tower body are arranged inmultiple layers, and every two adjacent layers of the baffles are opposite in inclination direction and arranged in a staggered mode. Asphalt can be effectively prevented from being coked at the air outlet, the air outlet area is large, the contact area of the asphalt can be increased, the contact with the asphalt is uniform, and the oxidation effect is good.
