AI Technical Summary

Technical Problem

The existing sludge drying system is drying under high temperature conditions and has high energy consumption; while the low-temperature drying technology covers a large area and has a small processing volume, making it difficult to take into account both low energy consumption and small footprint.

Method used

A sludge drying system is designed, adopting a modular structure design, including a primary cyclone, a secondary cyclone, a cyclone separator and a scraper conveyor, so as to achieve sludge drying through low-temperature drying (only 80℃ wind temperature) to reduce energy consumption and reduce floor area.

Benefits of technology

It realizes low-energy consumption sludge drying, the exhaust gas temperature is lower than 30℃, which is easy to deal with, the drying module covers a small area, low energy consumption, and high drying efficiency, and is suitable for various working conditions.
