Abstract
The invention discloses a denitration pipeline which comprises a steel pipe, wherein a rubber pipe body clings to the inner wall of the steel pipe; a plurality of ceramic pieces are embedded in the inner surface of the rubber pipe body; the ceramic pieces are uniformly arranged on the inner surface of the rubber pipe body; the ceramic pieces are cylinders, of which the diameters and heights are 5 mm; and the ceramic pieces are made from silicon nitride ceramic. The denitration pipeline integrates the advantages of a ceramic-lined pipe and a rubber-lined pipe and meanwhile solves the problems of no wear resistance of the rubber-lined pipe and falling of the ceramic-lined pipe. The life of the denitration pipeline is 8-10 times that of common rubber pipe and 5-8 times that of a ceramic-lined steel pipe or a polytetrafluoroethylene-lined steel pipe. The rubber pipe body and the ceramic pieces of the denitration pipeline are treated through specific technologies, are combined closely and cannot fall easily, so that the denitration pipeline is a very suitable denitration pipeline.
