The invention discloses a filler-type rectifying tower. The rectifying tower comprises a tower body, a tower kettle and a tower base, the tower body is provided with a liquid inlet, a gas inlet, a reflux opening and a gas outlet, the interior of the tower body is provided with a plurality layers of tower boards, each tower board is provided with a filler, the top end of the tower body is provided with liquid distribution devices, the tower kettle is provided with a reboiler return liquid inlet, a reboiler liquid inlet and a residual liquid outlet, the interior of the tower kettle is provided with a partition board and a flow guiding board, the partition board is arranged at the bottom of the tower kettle, the bottom of the tower kettle is divided into a left chamber and a right chamber by the partition board, the flow guiding board is arranged above the partition board obliquely, the downward oblique end of the flow guiding board is provided with a leak opening, and a fluid which flows down from the tower body flows out from the leak opening through guiding of the flow guiding board. The filler-type rectifying tower has high stability, and is convenient for maintenance, distribution of the fluid in the filler is good, mass transfer efficiency is relatively high, loss of the partial mass transfer efficiency is small, and separation efficiency is high.
Description
Technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a packed rectification tower. Background technique [0002] The distillation process is a typical unit operation for separating the mutual liquid mixture in chemical production. Its essence is multi-stage distillation, that is, under a certain pressure, the boiling point or saturated vapor pressure of each component of the mutual liquid mixture is used to make the light components (boiling point Components with lower or higher saturated vapor pressure) vaporize, and after multiple partial liquid phase vaporization and partial gas phase condensation, the concentration of light components in the gas phase and heavy components in the liquid phase gradually increase, thereby achieving separation. [0003] Typical rectification equipment is a continuous rectification device, including rectification tower, reboiler, condenser and so on. The rectification tower has two main types: ...
