污泥干化 Sludge Drying

該工藝的特點是利用鍋爐煙道氣余熱，不需要新增熱源，真的做到了節能、降耗、環保、以廢制廢。

本工藝為逆流烘干，負壓操作，其直接優點為：一是熱利用率高，二是進濕泥端的尾氣將濕泥預熱，濕泥中的水分已潮氣的形式散發出來，將從筒體尾部成品顆粒端的粉塵大部分吸附降解在筒體內進行內部循環，從而從干燥機系統出來的粉塵很少！

The biggest characteristic of this process is the use of boiler flue gas waste heat, don't need additional heat source, truly the energy saving, consumption reduction, environmental protection, waste with waste system.
This process for the counterflow drying, negative pressure operation, its immediate benefits for a thermal utilization is high, the second is preheat wet mud into the wet mud exhaust, and the moisture in wet mud has the form of the moisture, and the dust particles from the cylinder tail finished product side most adsorption biodegradation in the cylinder body for internal circulation, thus the dust out of the dryer system rarely！
