Description

Slurry supply system and absorption tower

Technical Field

Background

The absorber uses the difference in solubility of the gas mixture in the liquid absorbent to dissolve the readily soluble components in the absorbent and separate them from the other components. The absorber tower slurry supply sub-group is used to deliver slurry to the absorber tower. Because a large amount of foam is easy to generate in the absorption tower in the production process, and a vacuum environment is easy to form in a slurry supply pipeline connected with the absorption tower, slurry can flow backward and finally overflow from an atmospheric air outlet communicated with the atmosphere through the pipeline, and the surrounding environment is polluted.

In the prior art, a rectangular box body is additionally arranged at an air outlet of a slurry supply subgroup, a drain pipeline is led to a trench of an absorption tower from the bottom of the box body, and when slurry overflows or foams, the slurry overflows from the slurry supply subgroup pipeline to enter the rectangular box body for draining, and is discharged into the trench through the rectangular box body; meanwhile, a nozzle is additionally arranged at the upper opening of the rectangular box body for discharging sewage to inhibit the overflow of foam. The mode has a certain effect but cannot radically solve the problem that leakage still exists when the flow is large, the surrounding environment is seriously polluted due to long-term overflow, and the cleaning workload is large.
