污泥干化 Sludge Drying

該(gai)工藝的(de)(de)特點是利用鍋爐煙道氣(qi)余熱，不需要(yao)新增熱源，真的(de)(de)做(zuo)到(dao)了(le)節能、降耗(hao)、環(huan)保(bao)、以廢制廢。

本工藝為(wei)逆流烘干，負壓(ya)操作，其直接優點為(wei)：一是熱(re)利(li)用率高(gao)，二是進濕泥(ni)端(duan)的尾(wei)氣將濕泥(ni)預(yu)熱(re)，濕泥(ni)中的水分(fen)已(yi)潮氣的形式散發(fa)出來，將從筒體(ti)尾(wei)部成(cheng)品顆粒(li)端(duan)的粉塵大部分(fen)吸附降解在筒體(ti)內進行內部循環，從而從干燥機系統出來的粉塵很少(shao)！

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！
