Description

Rectifying tower

Technical Field

The invention relates to the technical field of vapor-liquid mass transfer, in particular to a rectifying tower.

Background

The rectifying towers are mainly divided into two types, namely a plate rectifying tower and a filler rectifying tower; the packing tower belongs to continuous contact type gas-liquid mass transfer equipment, the composition of two phases continuously changes along the height of the tower, and in a normal operation state, the gas phase is a continuous phase, and the liquid phase is a dispersed phase. However, when the liquid in the packed tower flows down along the packing layer, the liquid gradually tends to concentrate towards the tower wall, so that a wall flow phenomenon is generated, and gas-liquid two phases are unevenly distributed in the packing layer, so that the mass transfer efficiency is reduced.

The application number 202110730134.9 discloses a wall flow prevention efficient packing tower, high-pressure air is provided for an upper spray head through an air pump, the elastic membrane is rapidly ejected out by high-pressure air injection to overcome the magnetic attraction of an iron sheet and a magnetic ring, liquid in the elastic membrane is thrown onto the packing, the liquid is absorbed by the packing and participates in the reaction with the air again, the generation of wall flow is further reduced, and the liquid cannot be accumulated at the contact part of a liquid collecting ring and the packing. Application number: CN202010691332.4 discloses a packing absorber and an application method thereof, by arranging a main packing bin and an auxiliary packing bin. Most of the liquid sprayed by the liquid distributor directly enters the main filling bin to absorb target gas, and a small part of the liquid flows into the auxiliary filling bin along the inclined plane of the upper pressure grid plate through the first liquid through holes and the long annular notch which are both in the vertical direction in the axial direction, and flows out of the second liquid through holes after absorbing the target gas. The liquid can not directly leave the packing layer area due to the wall flow effect, and the influence of the wall flow effect on the working efficiency of the tower is effectively reduced.

Although the structure can reduce the generation of the wall flow phenomenon to a certain extent, in the actual working process, the steam at the bottom of the packing tower can quickly pass through the side edge part of the packing layer in the upward flowing process, so that the contact time between the side edge part of the packing side and the steam is reduced, and the mass transfer effect of the vapor-liquid two phases after contact is reduced.

In the initial state, the first electromagnetic bolt and the second electromagnetic bolt are ejected out, so that the rotating cylinder 506, the spiral block 502 and the rotating cylinder 503 are in a locking state; the water inlet 507 is not contacted with the screw block 502, the water inlet 507 is positioned above the upper surface of the screw block 502, and the through hole 505, the communication hole 504 and the water outlet 508 are communicated with each other (as shown in fig. 11); the electromagnetic telescopic column 12 is contracted, the telescopic end of the electromagnetic telescopic column 12 is not contacted with the vertical groove 11 on the supporting plate 9, the connecting part of the elastic metal net 803 and the rotary drum 503 is higher than the connecting part of the elastic metal net 803 and the bracket 7, and the connecting part of the elastic metal net 803 and the bracket 7 is in a concave state (particularly shown in fig. 10); the support plate 9 and the rotation gear 101 are both located above the ring gear 501.

When the device is used, firstly, liquid phase is conveyed to the inside of the tower body 1 through the liquid inlet pipe on the outer wall of the top of the tower body 1, the liquid phase entering the inside of the tower body 1 flows from top to bottom, vapor phase is conveyed to the inside of the tower body 1 through the air inlet pipe on the outer wall of the bottom of the tower body 1, the vapor phase entering the inside of the tower body 1 flows from bottom to top, the vapor phase and the liquid phase are in contact with each other in the inside of the tower body 1 for mass transfer, and the packing between the supporting plate 9 and the elastic metal net 803 provides a phase interface for the mass transfer of the vapor phase and the liquid phase.
