Description

Technical Field

[0001] The utility model relates to the technical field of coal tar distillation, in particular to multifunctional distillation equipment for coal tar extraction. Background Art

[0002] Coal tar distillation is a process that initially separates the components of coal tar into fractions enriched in one or more compounds based on their different boiling points. These fractions are generally divided into six types: light oil, phenol oil, tar, wash oil, anthracene oil, and asphalt. The process includes steps such as deslagging, homogenization, dehydration, desalination, and distillation.

[0003] The coal tar distillation equipment in the existing technology has relatively simple functions and can only perform a single distillation operation. It is unable to preheat the transported coal tar during the distillation, which increases the distillation time of the coal tar and affects the distillation efficiency. In addition, most of the waste gas generated by the distillation is directly discharged into the air without being filtered, causing air pollution. At the same time, during the coal tar distillation process, coke is easily attached to the inner wall of the tank and is not easy to fall off, resulting in waste. Utility Model Content
