Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization regeneration devices, in particular to a desulfurization regeneration device for purifying carbon dioxide tail gas. Background Art

[0002] There are a large number of sulfides such as hydrogen sulfide, carbon oxysulfide, sulfur dioxide, and carbon disulfide in carbon dioxide exhaust gas. After the existing exhaust gas desulfurization device uses the desulfurization solution, the solution contains a large amount of precipitate, which cannot be effectively cleaned up. During use, only part of the desulfurization solution reacts with the exhaust gas, and part of the desulfurization solution does not react with the exhaust gas. The solution that does not react with the exhaust gas is discharged together with the precipitate, wasting resources.

[0003] Therefore, in order to solve the above problems, a desulfurization regeneration device for purifying carbon dioxide tail gas is proposed. Utility Model Content
