Description

Technical Field

[0001] The utility model relates to the technical field of regeneration tower equipment, and more specifically to a regeneration tower which can fully desulfurize rich liquid. Background Art

[0002] The desulfurizer that absorbs acid gases such as COS, CS2, and H2S is called rich liquid. After the rich liquid pump increases the pressure, the trace impurities in the rich liquid are filtered out by the rich liquid filter. The rich liquid is heated by the lean liquid heat exchanger and the lean liquid flowing out of the bottom of the regeneration tower, and then goes to the upper part of the regeneration tower. The rich liquid passes through the regeneration tower from top to bottom and is fully in contact with the reverse-flowing stripping steam to remove the acid gases such as H2S in the rich liquid and analyze the acid gases.

[0003] In the prior art, when the acid gas in the rich liquid is decomposed by steam, the contact time between the steam and the rich liquid is too short, and the acid gas in the rich liquid cannot be fully decomposed. Therefore, the height of the regeneration tower needs to be increased, which increases the manufacturing cost of the regeneration tower.
