Description

Technical Field

[0001] The utility model relates to the technical field of coal ash carbon fixation, in particular to a coal ash solid waste carbon fixation device. Background Art

[0002] Coal ash carbon sequestration, also known as carbon sequestration, refers to measures to increase the carbon content of carbon pools outside the atmosphere, which can seal up excess carbon and prevent it from being released into the atmosphere. Carbon sequestration is mainly divided into two methods: physical carbon sequestration and biological carbon sequestration. Physical carbon sequestration is the long-term storage of carbon dioxide in mined oil and gas wells, coal seams and deep seas. Biological carbon sequestration is the conversion of carbon dioxide in the atmosphere into organic carbon and fixation in plants or soil, mainly through photosynthesis and chemoenergy.

[0003] During the production and processing of coal, some coal ash slurry will be produced. Coal ash slurry is a product prepared by mixing fly ash and water in proportion. Coal ash slurry can react with carbon dioxide to achieve the purpose of carbon sequestration. In the existing carbon fixation, carbon dioxide is usually directly introduced into the coal ash slurry. However, since the coal ash slurry is in a fluid state, carbon dioxide cannot be fully reflected on the inside of the coal ash slurry, resulting in poor carbon fixation effect of the coal ash slurry. Therefore, a coal ash solid waste carbon fixation device is proposed to solve the above problem. Utility Model Content
