Description
Technical Field
The utility model belongs to the technical field of environmental protection equipment, and particularly relates to a carbon dioxide absorption tower.
Background
At present, the technology of capturing, adsorbing and recycling carbon dioxide is a research hot spot in the field of environmental protection. A carbon dioxide absorber is generally required for the adsorption of carbon dioxide. Carbon dioxide absorption towers can be classified into three types according to gas-liquid phase contact forms: the first type is a plate column, a bubbling absorption column, a stirring bubbling absorption column and the like in which gas is dispersed in a liquid phase in the form of bubbles; the second type is an ejector, venturi, spray tower, etc. in which a liquid is dispersed in a gas phase in the form of droplets; the third type is a packed absorber, a falling film absorber, or the like in which a liquid contacts a gas phase in a film-like motion. The flow modes of the gas phase and the liquid phase in the carbon dioxide absorption tower comprise a countercurrent flow mode and a parallel flow mode, the common carbon dioxide absorption tower adopts the countercurrent flow mode, namely, the absorption liquid flows from top to bottom in the carbon dioxide absorption tower and is contacted with the gas flowing from bottom to top to perform absorption reaction, the absorption liquid after reaction is discharged from the bottom of the carbon dioxide absorption tower, and the gas after absorption is discharged from the top of the carbon dioxide absorption tower.
The absorption liquid is a chemical agent which can react with carbon dioxide in the gas to be absorbed to realize efficient absorption. Activating MDEA solution is one of the absorption solutions, and CO is removed by activating MDEA solution 2 Is a low-energy decarburization technology which is rapidly developed in recent years, and is increasingly applied to the purification process of natural gas and synthesis gas. The activated MDEA solution has low desorption temperature, stable chemical property and CO resistance 2 The gas absorption capacity is strong, and the reaction heat is small. Since the carbon dioxide absorption tower is generally made of a metal material, feCO is produced by using an activated MDEA solution as an absorption liquid for carbon dioxide absorption 3 Will dissolve in solution, but HCO 3- The presence of (C) inhibits FeCO 3 Promote the formation of passivation film on the metal surface and reduce the corrosion speed, so that the activation MDEA solution does not corrode the inner wall of the carbon dioxide absorption towerEven the activated MDEA solution is covered on the metal surface to isolate CO 2 The contact of the gas with the metal surface also prevents corrosion from occurring. The existing carbon dioxide absorption tower is poor in uniformity when spraying absorption liquid, the absorption reaction efficiency is reduced, the phenomenon of liquid bias flow possibly occurs, and part of the area of the inner wall of the carbon dioxide absorption tower is not covered by the activated MDEA solution, so that corrosion phenomenon possibly occurs, and the service life is reduced.
