U4 super three-phase centrifuge produced by Suzhou Younaite Machinery Manufacturing Corporation was adopted by Tongling Taifu Special Material Corporation, which not only optimized process flow, but solved problems of frequently fluctuation of tar moisture, high heating and dehydration energy consumption, long tank turnover time, and?difficult cleaning of tar residue that was adverse to production and external development process. Based on five months tracking of production process and quality detection of tar products, U4-type super three-phase centrifuge with 10 ~ 13 m3 / h feed volume, 3900 ~ 4000rpm revolving speed and 70 ℃ ~ 80 ℃ temperature could realize tar water content was stable at 1.8 %, total ash content was less than 0.04 %, toluene insoluble substance was less than 3.1 %, which greatly reduced energy consumption in production process.
