Description

Technical Field

[0001] The utility model relates to the technical field of absorption towers, in particular to a carbon dioxide absorption tower. Background Art

[0002] A carbon dioxide absorption tower is a device specifically used for capturing carbon dioxide, which is often applied to the reduction and recycling of carbon dioxide. It usually uses chemical absorption or physical adsorption methods to capture carbon dioxide. Carbon dioxide is separated from flue gas or air through specific absorbents or adsorbents, and then through a series of treatments, carbon dioxide is purified and compressed, ultimately achieving the reduction or recycling of carbon dioxide. Currently, the uniformity of the sprayed absorption liquid in the carbon dioxide absorption tower is usually poor, reducing the efficiency of the absorption reaction;

[0003] After retrieval, the utility model with the patent publication number CN219462997U discloses a carbon dioxide absorption tower. The flue gas containing carbon dioxide is introduced into the tower body through the air inlet, and the absorption liquid (activated MDEA solution) is introduced into the concentric spray component through the liquid inlet. Multiple spray nozzles of multiple spray units evenly distributed on the spray component spray the absorption liquid downward evenly, so that the absorption liquid falls into the packing layer. The flue gas to be absorbed enters the tower body through the air inlet, and the flue gas flows upward through the packing layer to chemically react with the absorption liquid. After the reaction is completed, the generated liquid flows to the bottom of the tower body and is discharged from the liquid outlet. After the flue gas after the absorption reaction is dried by the mist eliminator, it is discharged from the air outlet of the tower body. Although it is convenient to absorb carbon dioxide, when it is performing the absorption work, the packing layer is arranged in multiple layers from top to bottom, and the spraying degrees of the spray component on multiple packing layers are different, which will cause the absorption reactions of each packing layer to carbon dioxide flue gas to be different, thus reducing the absorption effect on carbon dioxide.

The spray head 9 is provided with a plurality of heads, and the plurality of spray heads 9 are respectively misaligned and communicated with each spray pipe 8. The protective cover 10 is arranged above each spray pipe 8, and a plurality of connecting columns are fixedly connected between the protective cover 10 and the adjacent spray pipe 8, which can increase the stability of the protective cover 10 installed above the spray pipe 8. The synchronous adjustment assembly is arranged between the protective box 7 and the plurality of protective covers 10.

[0045] As Figures 1 to 6 shown, the synchronous adjustment assembly includes a motor 11, a rotating rod 12, a gear 13 and a fixing block 14.

[0046] The connected rotating rods 12 can be rotated by the motor 11, and the remaining rotating rods 12 can be rotated simultaneously by the engagement of multiple gears 13, so that multiple protective covers 10 can be rotated at the same time, and thus multiple spray pipes 8 can be rotated at the same time through multiple connecting columns, and multiple spray heads 9 can be driven to rotate at the same time through multiple spray pipes 8, so as to facilitate the adjustment of the spray range, thereby facilitating all-round spraying of multiple packing layers 5.

[0052] The box door 21 is opened by the pull ring 22 to facilitate maintenance of the motor 11 in the installation box 20 .

[0053] In this embodiment, after the flue gas containing carbon dioxide enters the tower body 1 through the intake pipe 2, the absorbent is conveyed into the connecting pipe group 15 through the liquid inlet pipe 16, so that the absorbent can evenly enter the multiple spray heads 9 through the multiple spray pipes 8. At the same time, the motor 11 is started, and the motor 11 rotates the multiple rotating rods 12 simultaneously through the meshing of the multiple gears 13, so as to rotate the multiple protective covers 10 simultaneously. Thus, the multiple spray pipes 8 and the multiple spray heads 9 can be rotated simultaneously through the multiple connecting columns. Through the multiple spray pipes 8 and the multiple spray heads 9, the multiple packing layers 5 can be sprayed all-round, so as to facilitate the absorption of carbon dioxide in the flue gas. Then, through the demisting component 6, the absorbed flue gas can be dried, and the dried flue gas can be discharged from the tower body 1 through the outlet pipe 4.
