Description

Technical Field

[0001] The present invention relates to the technical field of carbon capture, and in particular to a multi-layer separation device for a carbon capture system. Background Art

[0002] Carbon capture is a process of pre-treating, absorbing, regenerating, compressing and storing flue gas generated in the industrial and energy production processes. The pre-treatment of flue gas is the core part of carbon capture. The main work includes denitrification, dust removal and desulfurization, so as to ensure the capture of carbon dioxide and store or utilize it after capture. However, in the prior art, when carbon capture is performed on flue gas, solution absorption is used for multi-layer separation. However, when carbon capture is performed on carbon dioxide, the amount of separation solution added is different from the concentration of carbon dioxide in the exhaust gas. There is a certain information lag, which makes it possible that too much or too little separation solution is added according to the amount of flue gas discharged. When too little separation solution is added, most of the carbon dioxide contained in the flue gas cannot be separated, making it difficult to ensure the carbon dioxide separation effect of the carbon capture separation work. If too much separation solution is added, all the carbon dioxide contained in the flue gas will be separated, but most of the separation solution is not added to the separation work, resulting in excessive waste of separation solution, which in turn causes a substantial increase in production funds. For this reason, we propose a multi-layer separation device for a carbon capture system. Summary of the invention

[0003] The object of the present invention is to provide a multi-layer separation device for a carbon capture system to solve the problem raised in the above background technology. However, in the prior art, when carbon capture is performed on flue gas, a solution absorption method is adopted to perform multi-layer separation. However, when carbon capture is performed on carbon dioxide in the multi-layer separation, there is a certain information lag between the amount of separation solution added and the concentration of carbon dioxide contained in the exhaust gas, so that when the separation solution is added according to the exhaust flue gas volume, too much or too little solution may be added. When the amount of separation solution added is too little, most of the carbon dioxide contained in the flue gas cannot be separated, and it is difficult to ensure the carbon dioxide separation effect of the carbon capture separation work. If the amount of separation solution added is too much, the carbon dioxide contained in the flue gas will be completely separated, but most of the separation solution is not added in the separation work, resulting in excessive waste of the separation solution, thereby causing a substantial increase in production funds.

The mechanism 6 transmits power to drive the extraction mechanism 7, so that the maximum distance moved by the driving mechanism 5 can drive the extraction mechanism 7 to extract the amount of separation solution required by the gas amount in the gas guide mechanism 2, thereby solving the problem of too much or too little separation solution introduced, thereby ensuring the smooth progress of the separation work, reducing excessive waste of the separation solution, and avoiding a substantial increase in production funds.

When the transmission mechanism 4 drives the second gear 55 to flip to the final angle position, that is, the extraction amount of the separation solution required for the gas, then the first motor 52 is controlled to rotate the first rotating rod 54, so that the first rotating rod 54 drives the touch block 56 to rotate clockwise, and at this time the second gear 55 is limited by the first gear 46. Then, when the touch block 56 touches the touch switch 58, the touch switch 58 feeds back an electrical signal to the first motor 52 to stop the operation.

[0056] During use, when the pumping rod 73 is driven by the limit block 66, the moving pumping rod 73 drives the second piston 72 to draw the separation solution into the pumping tube 71. When the extraction is completed and the separation solution in the pumping tube 71 needs to be pushed out, the solution is guided through the first liquid guiding tube 74, and the one-way delivery of the solution can be guaranteed by the first one-way valve 75.
