Summary: | The utility model discloses an anti-blocking device of a rotary air preheater. The system comprises a first heat exchanger arranged in a flue gas inlet duct in an air preheater, a second heat exchanger arranged in an intercooling secondary air duct in the air preheater, a pipeline for communicating the first heat exchanger with the second heat exchanger, and a first heat conduction oil tank and afirst heat conduction oil circulating pump which are arranged on the pipeline, the first heat exchanger and the second heat exchanger are arranged in the smoke inlet duct and the cold secondary air duct respectively, the first heat exchanger heats heat conduction oil, and the second heat exchanger heats the cold end, entering the cold secondary air duct, of the rotor so as to prevent blockage; meanwhile, hot air in the hot primary air outlet duct is introduced below the rotor, and high-pressure hot air is blown into the rotor through the nozzle, so that purging is realized; sodium hydroxide can be added into the purgi |
