Binocular wet sludge drying equipment

The invention discloses binocular wet sludge drying equipment which is composed of a sludge pump (2), a wet sludge preheating drum, a wet sludge drying drum and a pipeline, wherein the wet sludge preheating drum is connected with the sludge pump (2) through the pipeline (3); the wet sludge drying drum is connected with the wet sludge preheating drum through a sludge blanking channel (8). According to the invention, steam latent heat for sludge drying is sufficiently utilized, and wet sludge entering into the wet sludge drying drum can rapidly enter into water evaporation stage because the steam latent heat preheats the wet sludge, so that the efficiency of sludge drying is improved, and energy conservation and emission reduction of sludge drying is realized; the wet sludge preheating drum is used as a direct heat exchanger between high-temperature steam and the wet sludge without auxiliary equipment such as a heat exchange fan, thereby improving the efficiency of heat exchange and simplifying the whole drying
