Abstract
The invention provides a supporting structure of a positive grid in a filter. The supporting structure comprises a supporting frame which is used for fixing the positive grid in the filter, and a supporting column which is used for supporting the supporting frame, wherein a connecting column which can be connected with the supporting column is arranged on the lower surface of the supporting frame; and the diameter of the connecting column is smaller than that of the supporting column. According to the technical scheme, the supporting structure of the positive grid in the filter provided by the invention has the advantages that the diameter of the supporting column is greater than that of the connecting column, so that a step is formed between the supporting column and the connecting column; to-be-treated air which is blown from the bottom of the supporting column moves upwards along the outer surface of the supporting column; dust particles carried in the air are effectively prevented from being attached to the connecting column, and the surface cleanness of the connecting column is ensured; current generated by the positive grid is prevented from being directly discharged to a lower discharging network; sparks are avoided; and equipment are guaranteed to safely run.
