Description

Technical Field

[0001] The utility model relates to the technical field of carbon dioxide mineralization, in particular to a carbon dioxide curing kettle capable of secondary pressure replenishment. Background Art

[0002] Global climate change caused by greenhouse gas carbon dioxide emissions has become a major issue of common concern to the world. Research and development and industrial trials of large-scale carbon dioxide disposal technologies are being widely carried out at home and abroad. Geological storage, marine storage and mineralization fixation are the main ways to dispose of carbon dioxide on a large scale. Carbon dioxide mineralization is not only seen as an effective way to achieve stable storage of carbon dioxide, but also an effective way to achieve large-scale resource utilization of carbon dioxide. It refers to imitating the mineral absorption process of carbon dioxide in nature, using alkaline or alkaline earth metal oxides, such as calcium oxide or magnesium oxide, to react with carbon dioxide to produce stable carbonate compounds such as calcium carbonate and magnesium carbonate. The carbonate compounds produced in the process of carbon dioxide mineralization can exist stably for a long time and do not need to be monitored, and the environment The risk is relatively small. There is great potential for reducing carbon dioxide emissions by utilizing the mineral carbonation conversion process on the earth. It can realize the in-situ fixation and conversion utilization of carbon dioxide, and is considered to be one of the most promising carbon dioxide disposal methods. It uses a large amount of difficult-to-handle carbon dioxide gas to cure autoclaved bricks, which can not only realize the on-site solidification of carbon dioxide emitted from multiple sources to achieve a low-carbon economy, but also achieve waste treatment with waste, and improve the high energy consumption and high pollution of the traditional autoclaved brick production process. At present, the existing carbon dioxide curing kettle pressure replenishment requires the use of a carbon dioxide booster to inject carbon dioxide into the curing kettle for pressure maintenance, which increases the autoclaving cost of fly ash bricks. At the same time, when the sealing cover is opened, a high concentration of carbon dioxide will be emitted, which will lead to an increase in the carbonic acid concentration in the blood of the staff near the curing kettle, causing acidosis and affecting the health of the staff.

[0003] For example, the utility model patent with publication number CN220576290U discloses a carbon dioxide mineralization curing reaction device, which belongs to the field of carbon dioxide mineralization equipment. It includes a support frame with a notch at the bottom and a slide groove therein; a sleeve rotatably arranged on the support frame. The device needs to use a carbon dioxide booster to inject carbon dioxide into the curing kettle to maintain the pressure, which increases the autoclave cost of fly ash bricks. At the same time, when the sealing cover is opened, a high concentration of carbon dioxide will be discharged, which will cause the carbonic acid concentration in the blood of the staff near the curing kettle to increase, causing acidosis and affecting the health of the staff.
