Description

Technical Field

[0001] The utility model relates to the technical field of distillation equipment, in particular to a distillation separation device for producing aromatic solvents. Background Art

[0002] Distillation is a separation process that utilizes the different volatilities of components in a mixture to separate them. Distillation is usually carried out in a distillation tower. The gas-liquid two phases contact each other through countercurrent flow to carry out interphase heat and mass transfer. The volatile components in the liquid phase enter the gas phase, and the less volatile components in the gas phase transfer to the liquid phase. Therefore, almost pure volatile components can be obtained at the top of the tower, and almost pure less volatile components can be obtained at the bottom of the tower. The feed liquid is added from the middle of the tower. The tower section above the feed port further concentrates the volatile components in the rising vapor, which is called the distillation section; the tower section below the feed port extracts the volatile components from the descending liquid, which is called the stripping section. The vapor drawn out from the top of the tower is condensed, and a part of the condensate is returned to the distillation tower from the top of the tower as reflux liquid, and the remaining distillate is the top product. The liquid drawn out from the bottom of the tower is partially vaporized by the reboiler, and the vapor rises along the tower, and the remaining liquid is the bottom product. The ratio of the amount of liquid refluxed into the tower from the top of the tower to the amount of the top product is called the reflux ratio, and its size will affect the separation effect and energy consumption of the distillation operation.

[0003] However, the existing equipment does not have a distillation tower with a mobile structure. Due to its heavy weight, lifting equipment is required when the equipment needs to be moved, which cannot achieve rapid movement and increases the difficulty of transfer. Therefore, a distillation separation device for the production of aromatic solvents is proposed. Utility Model Content
