Plate-type packed rectifying tower

Abstract

The invention belongs to the technical field of chemical equipment, and particularly relates to a plate-type packed rectifying tower. The plate-type packed rectifying tower comprises a tower body, a tower tray and a controller; a liquid backflow pipeline is arranged on the upper portion of one side of the tower body; an air inlet is formed in the lower portion of the same side of the tower body; afeeding port is formed in the lower portion of the other side of the tower body; an air outlet is formed in the center of the top of the tower body; a discharging port is formed in the center of thebottom of the tower body; the tower tray comprises a tower plate, an overflow weir, a downcomer and a liquid receiving tray; the controller is mounted in the middle of the outer wall of the tower bodyand used for controlling the rectifying tower to automatically operate; and an adjusting module and a sealing module are arranged on the tower plate. According to the plate-type packed rectifying tower of the invention, the adjusting module is arranged to sense the liquid leakage degree in the tower, and the sealing module is triggered in due time; the sealing module changes the working state ofthe tower plate through movement, so that gas is manually pressurized, a gas-liquid contact area is increased, and therefore, liquid leakage phenomena are reduced, and the efficiency of the plate is improved.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment, in particular to a plate-type packing rectification tower. Background technique [0002] In the process of preparing chemical products, rectification towers are often used to separate the components of raw materials. The basic principle is to partially vaporize and partially condense the liquid mixture multiple times, and use the characteristics of different volatilization degrees of each component to achieve the purpose of separation. . It mainly includes a packed rectification tower and a plate packed rectification tower. In the prior art, the plate tower performs mass transfer and heat transfer through layering, and the gas-liquid two phases on each tray must maintain close and sufficient contact. Provide a sufficiently large and constantly updated interphase contact surface for the mass transfer process to reduce the mass transfer resistance. In the tower, the gas-liquid two-phase...

Problems solved by technology

[0005] This patent can improve the rectification coefficient to a certain extent and strengthen the gas-liquid mass transfer process; but this patent cannot solve the problem of insufficient gas pressure and insufficient contact between gas and liquid in the rectification tower, resulting in serious liquid leakage, which greatly reduces the efficiency of the tray , which affects the production efficiency; accordingly, the present invention proposes a rectifying column with plate packing
