Description

Technical Field

[0001] The utility model relates to the technical field of gas purification, in particular to a carbon capture device. Background Art

[0002] Flue gas usually contains carbon dioxide, and carbon dioxide needs to be removed before the flue gas is discharged. In the prior art, the methods for absorbing carbon dioxide mainly rely on filter elements or liquids capable of absorbing carbon dioxide.

[0003] CN212017304U discloses a novel carbon dioxide purification device for urea production. This device uses a impurity-removing liquid to absorb carbon dioxide. Specifically, a umbrellalike liquid sealing surface is formed by spraying the impurity-removing liquid. When carbon dioxide passes through, the impurity gas is absorbed.

[0004] The problem with the above solution is that the contact area between unit carbon dioxide and unit impurity-removing liquid is limited. Therefore, the effect of the impurity-removing liquid cannot be fully exerted. Although the contact time between carbon dioxide and the impurity-removing liquid can be increased by slowing down the flow rate of carbon dioxide, the gas treatment efficiency is also affected. Summary of the Utility Model

The rotating assembly rotates the air inlet pipe, and the air inlet pipe rotates the blades through the disc. A large number of bubbles are stirred out of the fly ash inlet / outlet liquid by the blades, which can increase the contact area between the flue gas and the fly ash inlet / outlet liquid and improve the purification effect.
