Description

Technical Field

[0001] This utility model relates to the technical field of buffer tanks at the top of coal tar distillation towers, specifically a buffer tank at the top of a coal tar distillation tower. Background Technology

[0002] Coal tar is a dark brown, viscous, oily liquid obtained during the dry distillation and gasification of coal. It is an important chemical raw material. Coal tar usually contains a large amount of water and impurities. The water is mainly divided into free water and emulsified water. Free water can be separated by sedimentation, but emulsified water and impurities are completely integrated into the coal tar, which affects the subsequent deep processing of coal tar. Therefore, there is an urgent need for a buffer tank at the top of the coal tar distillation tower.

[0003] Currently, the buffer tank at the top of the coal tar distillation tower is inconvenient for filtering water vapor, which affects subsequent processing. It is also inconvenient to clean the buffer tank, which affects its performance. Utility Model Content
