| description | The invention relates to a method for judging wear of a catalyst. The method comprises the following steps: S1, preparing a reference station and a measuring column; s2, after the measuring columns correspond to the holes of the catalyst unit body, the reference table is pressed downwards until the lower surface of the reference table abuts against the upper surface of the unit body, and then the distance of each measuring column extending out of the reference table is obtained through detection; s3, calculating the difference value between the distance of the measuring column extending out of the reference station and the length of the measuring column, wherein the difference value is the wear length of the hole corresponding to the unit body; and S4, according to the wear length, setting the wear grade of the catalyst, and based on the position of each unit body of the catalyst module in the denitration reactor, making a wear distribution diagram recording the wear grade corresponding to the unit body.
