Technical Field
[0001] This utility model belongs to the field of chemical equipment technology, and in particular relates to an improved high-efficiency distillation column. Background Technology
[0002] Distillation columns are among the most commonly used equipment in chemical production. Based on the structural type of the gas-liquid contact components within the column, they can be classified into plate columns and packed columns, each suitable for different chemical production applications. Packed columns are continuous gas-liquid mass transfer devices, where the gas and liquid phases continuously flow in countercurrent contact for mass and heat transfer. The concentrations of the gas and liquid phase components change continuously along the column height. Existing multifunctional high-efficiency distillation columns include a column body, condenser, reflux tank, reboiler, trays, downcomer, overflow weir, demister grid, packing layer, support frame, preheater, perforations, outlet, PTFE tube, and perforated grid. However, these multifunctional high-efficiency distillation columns present challenges in terms of inconvenience for real-time online concentration monitoring and concentration adjustment during operation.
