Anti-blocking ultralow-emission filter material for tail of waste incineration plant

The utility model belongs to the technical field of filter materials, and particularly relates to an anti-blocking ultralow-emission filter material for the tail of a waste incineration plant, which comprises a pipeline anti-blocking mechanism and a filter mechanism, the pipeline anti-blocking mechanism comprises a main pipeline, a step pipeline is arranged at the end part of the main pipeline, the step pipeline is communicated with the inside of the main pipeline, and the filter mechanism is arranged in the step pipeline. A limiting protruding block is arranged at the end, close to the main pipeline, of the interior of the step pipeline, the filtering mechanism comprises a filtering frame, the interior of the filtering frame is hollow, the filtering frame is arranged between the main pipeline and the limiting protruding block, and the surface of the side, away from the main pipeline, of the filtering frame is in a cross shape. Sliding grooves are evenly formed in the surface of the side, away from the main p
