Oxidized-air conveying pipeline made of fiber glass reinforced plastics

The invention relates to an oxidized-air conveying pipeline made of fiber glass reinforced plastics. The oxidized-air conveying pipeline comprises an inner anti-seepage layer and an outer anti-seepage layer, wherein an inner anti-corrosive layer and an outer anti-corrosive layer are arranged between the inner anti-seepage layer and the outer anti-seepage layer; a fiber-glass-reinforced-plastic structure layer is arranged between the two anti-corrosive layers; the pipeline comprises a main pipe and a branch pipe which is communicated with one end of the main pipe to form a nine-square shape; air outlet holes are uniformly and dispersively formed in the branch pipe; and spikes are arranged on the edges of the air outlet holes in the pipeline. The oxidized-air conveying pipeline has the advantages that the anti-seepage and anti-corrosive effects can be effectively achieved, relatively large air bubbles can be split to form air bubbles with relatively small diameter and the contact area between air and slurry is enlarged, so that the oxidation rate is increased.
