AI Technical Summary

Technical Problem

Existing rotary dryers have high exhaust gas temperatures that cannot be utilized, resulting in resource waste. Furthermore, the independent assembly of the equipment leads to large investments, high operating costs, and low efficiency.

Method used

Design a rotary drying and cooling tube bundle air-material countercurrent integrated machine. The machine body is divided into a hot air drying section and a tube bundle cooling section. The airflow is opposite to the material direction. The high-temperature exhaust gas is used to preheat the wet material. The dust flows countercurrently and mixes with the material. The hot air drying and cooling tube bundle are integrated.

Benefits of technology

Effectively utilizing waste heat from exhaust gases can reduce emission temperatures, lower energy consumption, reduce dust, lower operating costs, and improve production efficiency.
