摘要
This paper reported a sludge disposal technology that uses 100-200 degrees C flue gas to dry sludge through a systematic analysis of the relationship between sludge drying rate/temperature and moisture content. Using this direct drying technology, the sludge drying capacity for the dryer tested can reach 86tonsd(-1) at 160 degrees C. The experimental results show this technology can also preserve 95% calorific value in the sludge, and remove 16-42% PM2.5, 26-55% PM10, and 7-25% SO2 from the flue gas. The exhaust gas from the sludge dryer consists mainly of chain alkanes while benzenes only 9.65% when dried at 100 degrees C.
