Description

Technical Field

[0001] The utility model relates to the technical field of carbon dioxide capture, cooling and desulfurization, and in particular to an integrated device for carbon dioxide capture, cooling and desulfurization. Background Art

[0002] Carbon dioxide capture refers to the process of passing the flue gas after combustion through separation equipment to obtain carbon dioxide with a higher concentration. The captured carbon dioxide gas needs to be cooled and desulfurized, so the existing integrated carbon dioxide capture, cooling and desulfurization equipment has been continuously innovated and developed. It can be seen that the current integrated carbon dioxide capture, cooling and desulfurization equipment basically meets people's needs, but there are still some problems.

[0003] For example, the patent document with announcement number CN211753623U discloses an integrated desulfurization, dust removal and cooling device, which uses a cooling dust collector and a sedimentation tank as a cycle, adds a desulfurizer to the spray liquid, and performs main desulfurization and dust removal on the flue gas. The desulfurization efficiency is over 90% and the dust removal rate is over 60%, which reduces the process pressure of desulfurization and dust removal of subsequent supporting removal devices. At the same time, the flue gas is cooled during the spraying process, which creates favorable conditions for the denitrification reaction of the subsequent wet removal device. The movement path of the flue gas is planned into a continuous zigzag shape through multiple isolation barriers, which enhances the dust removal, desulfurization and cooling effects of the cooling dust collector. This device is used as a flue gas pretreatment device in conjunction with the subsequent desulfurization, denitrification and dust removal system, which enhances the flue gas treatment effect, shortens the process flow, and reduces investment and use costs.

[0004] However, when the above-mentioned device is actually used, the movement path of the flue gas is planned to be a continuous zigzag shape through multiple isolation barriers, which enhances the dust removal, desulfurization and cooling effects of the cooling dust collector. However, the movement path of the flue gas is only planned through multiple isolation barriers, which makes it difficult for the flowing flue gas to effectively contact the desulfurizer, thereby resulting in a decrease in the efficiency of the desulfurizer in treating the flue gas. Therefore, an integrated desulfurization, dust removal and cooling device is urgently needed to solve the above problems. Utility Model Content
