Abstract

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
