摘要:

针对高湿高粘污泥干燥难题,对市政污泥水分特性和干燥特性进行分析,对普通回转圆筒干燥机关键部件结构进行了优化设计,并进行了工业模拟试验。结果表明:内部带链条、抄板、打散轴等自清理构件的自清理打散回转干燥机与普通回转圆筒干燥机相比,具有防粘、防团聚效果好,干燥强度大,干燥效果理想等优点,为市政污泥深度脱水工艺与装置的开发与应用推广提供了有益的理论支持。

Abstract:

Owing to the problems of drying high-humidity and high-viscosity sludge, this paper analyzes the water characteristics and drying characteristics of municipal sludge to optimize the design of the key components of ordinary rotary cylinder dryer and conduct industrial simulation test. The results show that the self-cleaning and dispersing rotary cylinder dryer with internal self-cleaning components such as chains, scraping plates, and dispersing shafts has better a antisticking and antiagglomeration effect as well as higher drying power and more ideal drying effect than the ordinary rotary drum dryers. It provides useful theoretical support for the development and application promotion of municipal sludge deep dewatering processes and devices.

Key words: municipal sludge, industrial test, rotary cylinder dryer
