Method and equipment for granulating wet sludge soft particles

The invention discloses a method for granulating wet sludge soft particles. Sludge after being pressed and filtered is extruded into sludge strings by a sludge string extrusion machine at the top of a mixing tank, combustible powder is sprayed to the sludge strings for serving as an isolator by adopting a powder spraying machine of a powder spraying gun which is fixedly connected on the side wallof the mixing tank in the process that the sludge strings fall from top to bottom, the sludge strings coated with the combustible powder fall on a turntable granulating machine of which the bottom islaid with the combustible powder, and soft body granulation is carried out under the rotation of the turntable granulating machine to form dispersive wet sludge soft particles. The invention also discloses equipment for realizing the method. The invention simplifies a subsequent sludge drying process; the sprayed combustible powder can be used as the isolator, which is beneficial to sludge granulation and solves the problems of sludge caking and wall sticking effectively; moreover, the sprayed combustible powder can also act as a combustion-supporting function when sludge is incinerated; and the invention has simple equipment, low energy consumption and high benefit, is safe and sanitary, is convenient for popularization and use and can promote the industrialization progress of the dryingincineration of the sludge.
