| description | The utility model discloses a filtering device for pulverized coal impurities of a blast furnace coal injection system, and relates to a filtering device in a blast furnace pulverized coal injection tank. The filtering device comprises a pulverized coal discharge pipe, wherein a feed port of the pulverized coal discharge pipe, which is positioned in the blast furnace pulverized coal injection tank, is connected with a pipeline which has the same diameter as that of the pulverized coal discharge pipe; the pipeline is provided with a hole; or a hole is directly formed in the part of the pipe body of the pulverized coal discharge pipe, which is positioned above the feed port in the blast furnace pulverized coal injection tank. The filtering device has the advantages of easiness and convenience in manufacturing, low manufacturing cost, obvious use effect and capabilities of perfectly solving the failure of blockage of a coal delivery main pipeline and a pulverized coal spray gun by foreign matters of the coal inj |
