Dustproof system for coal conveying belt of thermal power plant

The invention relates to a dustproof system for a coal conveying belt of a thermal power plant. The dustproof system comprises a dustproof cover, a coal dropping buffer assembly and a dry fog pipe. The dustproof cover is arranged above the coal conveying belt. A coal dropping pipe extends into the dustproof cover from the top of the dustproof cover. A discharge opening of the coal dropping pipe isarranged above the coal conveying belt. The coal dropping buffer assembly is arranged on the inner side of the dustproof cover and is also arranged below the discharge opening of the coal dropping pipe. The dry fog pipe is arranged on the dustproof cover in the width direction of the coal conveying belt. A plurality of spray heads are arranged on the dry fog pipe at intervals and are arranged towards the coal dropping buffer assembly. The dustproof system has the advantages that the coal dropping buffer assembly is arranged in the dust cover to buffer coal flow discharged from the coal dropping pipe; and meanwhile, t
