Description

Technical Field

[0001] The utility model belongs to the technical field of coal tar processing equipment, in particular to an absorption tower structure in a coal tar deep processing process. Background Art

[0002] Absorption tower is a device for realizing absorption operation, which is divided into three categories according to the contact form of gas-liquid phase. The first category is plate tower, bubbling absorption tower and stirred bubbling absorption tower, in which gas is dispersed in liquid phase in the form of bubbles; the second category is ejector, venturi and spray tower, in which liquid is dispersed in gas phase in the form of droplets; the third category is packed absorption tower and falling film absorption tower, in which liquid contacts gas phase in film-like motion. The flow mode of gas and liquid in the tower can be countercurrent or cocurrent, and countercurrent operation is usually adopted. The absorbent is added at the top of the tower and flows from top to bottom, contacting with gas flowing from bottom to top. The liquid absorbed by the absorbent is discharged from the bottom of the tower, and the purified gas is discharged from the top of the tower.

[0003] Existing absorption towers need to install multiple single overflow float valve tower plates or filter screens to place different filter materials to filter the processed products. However, when the filter components are used for too long, impurities are likely to gradually clog the pores of the filter components. When used for a long time, the processed products are gradually clogged in multiple filter components, which makes it easy for the gas phase load in the tower to gradually increase. In severe cases, airflows may interfere with each other, causing the local gas velocity around the filter components to be too high, which may easily cause dry gas to carry liquid inside the absorption tower, reducing the working efficiency of the absorption tower. Therefore, we propose an absorption tower structure for coal tar deep processing, which is easy to use and needs to be developed urgently. Utility Model Content
