Multilayer heterogenic baffling ring high-speed centrifugal rectifying tower

Abstract

The invention discloses a multilayer heterogenic baffling ring high-speed centrifugal rectifying tower which comprises moving equipment, fixed equipment, a partition plate and relevant gas and liquid phase inlets and outlets, wherein the moving equipment comprises a motor rotating shaft penetrating through a shell and multiple layers of brake disks; the fixed equipment comprises multiple layers of fixed disks and a shell; and the gas outlet and the liquid inlet are positioned at the bottom of the shell; and the top of the shell is provided with a gas inlet and a liquid outlet. In the shell, the partition plate which is in bolt connection with the shell divides the shell into multiple layers; and gas-liquid flow between the layers is just finished in a gas-liquid channel of a liquid distributing chamber. Each layer is divided into a shell side and a centrifugal separating area by the disks. In the center of the shell, multiple brake disks are connected in series and fixed at the periphery of the motor rotating shaft, and heterogenic plate concentric baffling rings with different radii are fixed on the disks. At upper spaces of the brake disks, the heterogenic plate concentric baffling rings with different radii and the baffling rings are distributed at intervals and fixed on multiple layers of fixed disks which are in seal connection with the partition plate. The invention can effectively reduce the pressure drop of a rectifying tower and strengthen the gas-liquid mass transfer effect, has high operational flexibility, obviously reduces the tower height under the same theoretical plate and reduces equipment investment.

Description

technical field [0001] The invention relates to a high-speed centrifugal rectification tower, in particular to a high-speed centrifugal rectification tower with multi-layer special-shaped baffle rings. It can be widely used in processes involving gas-liquid contact mass transfer such as rectification and absorption in petrochemical, pharmaceutical, chemical, light industry and other industries. Background technique [0002] Distillation and absorption are typical unit operations for separating liquid mixtures by mass and energy transfer between liquid and gas phases in countercurrent contact. Column equipment is a gas-liquid mass transfer equipment that can realize two separation operations of rectification and absorption. Its structural form can basically be divided into two categories: plate tower and packed tower. A reasonable tray tower has a high empty tower speed, so it has a large production capacity, stable tray efficiency, low cost, easy maintenance and cleaning, ...

AI Technical Summary

Problems solved by technology

However, the disturbance of the fluid during gas-liquid contact is not good, the mass transfer efficiency is relatively low, and the stability of the equipment is not good. At the same time, it is not convenient to determine the number of theoretical plates, which is not conducive to the design of the distillation column size.
