| Abstract: | The increasing quantity of high-humidity and high-viscosity solid wastes has caused serious damage to the ecological environment. Drying reduction is a key step for resource utilization. This is a process that uses heat energy to remove moisture from materials. Due to the characteristics of high water content and high viscosity, it has caused problems such as easily sticking to the wall, slowshaping and low drying efficiency, which puts forward more stringent requirements on the design of drying equipment. This article introduced the types and characteristics of common high-humidity and high-viscosity solid wastes, analyzed the difficulties in drying reduction, and reviewed the research progress of dryers for high-humidity and high-viscosity solid wastes. |
