Abstract: Disclosed are a multi-stage gravity-type sludge drying apparatus and a sludge drying method using the same. The drying apparatus includes: a dryer, a preheater, a steam generator, a filter, a steam or water separation buffer tank, a steam compressor, a cooling water pump, a sealed discharge device, pipes and valves. The dryer includes several indirect dryer modules. The transportation of sludge in the dryer is achieved by gravity. The inner cavity of respective indirect dryers is filled with high-temperature steam to dry the sludge by indirect heating. The condensate water in the cavity is recycled and fed into the preheater to perform preheating and impurity removal on the wet sludge. The secondary steam generated in the dryer is filtered, compressed and overheated to become a new heat source for indirect heating in the cavity and convection drying at a bottom of the dryer.

Abstract: Liquid organic material is controllably delivered to a receptacle located in the center of a heated surface capable of horizontally rotating about its central axis. As the heated surface rotates, material deposited within the central receptacle is forced outwardly and across the rotating surface. As the material moves radially, it evaporates into a vapor which is then transported to one or more nozzles. From the nozzles, the vapor is applied to a substrate and condensed. Relative to existing devices and methods, the present invention enables the evaporation of a wider variety of organic liquids, greater reliability in continuous operation, a decrease in maintenance, and a larger and more constant material flow rate.
