The utility model relates to dyeing sludge drying equipment. The dyeing sludge drying equipment is characterized in that a gas phase outlet of a disc dryer of the equipment is connected to a feed port of the disc dryer sequentially by virtue of a dust remover, a venturi dust remover, a cooler, a heat exchanger and a circulating fan, so that odor-containing high-humidity tail gas evaporated out by the disc dryer is subjected to dust removal, dehumidified and cooled and then is heated so as to serve as hot carrier gas of the disc dryer for use; the gas phase outlet of the disc dryer is connected to the venturi dust remover and a wastewater pipeline sequentially by virtue of the dust remover, the venturi dust remover, the cooler and a washing pump, so that the odor-containing high-humidity tail gas evaporated out by the disc dryer is subjected to dust removal, dehumidified and cooled, after most of steam in the odor-containing high-humidity tail gas is condensed, steam condensate serves as washing water for circularly spraying the odor-containing high-humidity tail gas; a heat-transfer medium outlet of the disc dryer is connected to a heat-transfer medium inlet of the heat exchanger sequentially by virtue of a recovery tank and a condensate pump, so that heat of a heat-transfer medium is fully utilized. The dyeing sludge drying equipment has the advantages of small discharge amount of exhaust gas and wastewater, energy conservation and the like.
