Coal tar dehydration system

The utility model provides a coal tar dehydration system which comprises a dehydration tank, a steam heating coil and a tar recovery device, the steam heating coil is arranged in the dehydration tankand is used for heating the coal tar in the dehydration tank so as to evaporate moisture in the coal tar; the tar recovery device is communicated with the dehydration tank and is used for recovering the dehydrated coal tar. Meanwhile, steam is adopted as a heat source, so that the cost is low, and the problem that in the prior art, the cost is high when an electrolytic dehydration and desalinationdevice is adopted for carrying out dehydration treatment on the coal tar is solved. 本实用新型提供了一种煤焦油脱水系统，包括脱水槽、蒸汽加热盘管和焦油回收装置，脱水槽用于盛装煤焦油；蒸汽加热盘管设置在脱水槽内，蒸汽加热盘管用于对脱水槽内的煤焦油进行加热以使煤焦油内的水分蒸发；焦油回收装置与脱水槽连通，焦油回收装置用于回收经过脱水后的煤焦油。从而快速对煤焦油进行脱水处理并满足煤焦油加氢延迟焦化装置对于原料油的含水量要求，同时采用蒸汽作为热源，成本较低，解决了现有技术中采用电解脱水除盐装置对煤焦油进行脱水处理成本较高的问题。
