The present invention relates to a sludge drying apparatus, and in detail, the sludge of wastewater has a high heat source utilization rate and a low investment in installation. The heat storage rail continuous sludge drying apparatus can be saved.

In general, sewage sludge, that is, sewage sludge, is generated in a wastewater treatment plant and a sewage treatment plant for purifying wastewater. Since these sludges are themselves pollutants, they must be transported to the outside of the sewage treatment plant periodically for disposal. Therefore, the processing is expensive and laborious. Therefore, the method of recycling sludge has been considered. Among them, the most efficient method is to use sludge as a dry sterilization fertilizer or auxiliary fuel.

Conventional sludge dryers are suitable for small capacity facilities and are not suitable for large capacity sludge treatment. In addition, the thermal efficiency was low, and maintenance had a disadvantage.

In order to solve this problem, a rotary drying apparatus of a direct drying method has been developed. This drying device is configured to dry while the drying object (sludge) is naturally transported down along the inclined surface by rotating the drying furnace inclined. Therefore, the devices for rotating the inclined drying furnace have to be designed in accordance with the inclined structure, which makes it difficult to manufacture the device, and because it is driven in an inclined state, there are frequent failures and difficult repairs. In addition, since sludge has a viscosity, there is a problem that a dried object to be dried is not properly discharged by a slight inclined structure.

As described above, urban sludge treatment is an environmental protection problem to be inevitably solved internationally, and sludge discharged during sewage treatment is a large source of pollution because it contains a large amount of bacteria, parasites, heavy metals, organic matters, and the like.
