Description

Technical Field

[0001] The utility model relates to the technical field of CO2 separation membrane production, in particular to an extraction device for CO2 separation membrane production with a protective structure. Background Art

[0002] Due to the scale of cement production and the characteristics of its production process (process emissions), the cement industry is considered to be one of the main sources of anthropogenic CO2 emissions, accounting for 8% of global carbon emissions. High-emission industries will have to assume more carbon emission reduction obligations, so the cement industry is under tremendous pressure to reduce carbon emissions. CO2 separation membrane refers to a gas separation membrane that can separate carbon dioxide from mixed gases.

[0003] The production process of the CO2 separation membrane in the prior art is: two or three of lithium carbonate, sodium carbonate and potassium carbonate are mixed and one or more of calcium carbonate, strontium carbonate and magnesium carbonate are added, and the mixture is heated to form a molten carbonate, and the molten carbonate is impregnated into a porous skeleton by an impregnation method to obtain a mixed conductor carbon dioxide separation membrane. However, a large amount of smoke and dust will be generated during the grinding process of the material. The smoke and dust overflow from the feed bin will pollute the environment, and the crushed powdered material is very easy to clog the sieve holes, causing technical problems such as poor material discharge. In addition, the raw material grinding-heating mixing-impregnation extraction process in the prior art cannot be integrated into one device, and the production efficiency is low.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and an extraction device for CO2 separation membrane production with a protective structure is proposed. Utility Model Content
