Embodiment Construction
[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0024] A kind of processing method of coal tar is characterized in that comprising the following steps:
[0025] 1) Dehydration of tar: tar must remove water before distillation. Dehydrated tar can reduce heat consumption in the distillation process, increase equipment production capacity, and reduce system resistance of continuous distillation heating. After the general tar is evenly finished, part of the water is mixed in the tar, and it needs to be heated and left for 24 hours to separate the oil and water, and then dehydrated to meet the production requirements.
[0026] Process route: incoming inspection of raw materials—put into the underground unloading tank—send to the tar dehydration tank—send to the raw material tank for production.
[0027]2) Tar distillation: using a continuous distillation device, after the raw tar is left to sta...
