Description

Technical Field

[0001] The invention relates to the technical field of resource utilization, and in particular to a method and a device for co-processing recycled gelled composite material particles and industrial waste gas containing carbon dioxide. Background Art

[0002] Recycled cementitious composite particles, such as waste concrete and / or waste mortar, have the characteristics of large porosity, high water absorption, low bulk density and high crushing index. As a result, the cementitious composite materials prepared with recycled cementitious composite particles as aggregates or admixtures have different degrees of reduction in impermeability and mechanical properties after hardening compared with ordinary cementitious composite materials prepared with quartz sand and gravel as aggregates, and the quality is unstable. Therefore, the utilization rate of recycled cementitious composite particles is low.

[0003] Industrial waste gas refers to the general term for various pollutant gases discharged into the air during fuel combustion and production processes in the factory area of ​​an enterprise. The components of industrial waste gas are complex, such as carbon dioxide, nitrogen dioxide, sulfur dioxide and particulate matter. Direct discharge into the atmosphere will pollute the air. Moreover, these substances enter the human body through the respiratory tract through different pathways. Some of them cause direct harm, while others have an accumulation effect, which will more seriously endanger human health. Summary of the invention

[0058] After obtaining the microorganism-oxygen release-in-situ induced deposition composite medium and the carbonization pretreatment material, the present invention sprays the microorganism-oxygen release-in-situ induced deposition composite medium into the treatment bin containing the carbonization pretreatment material to perform microbial enhanced treatment to obtain enhanced regenerated gelled composite material particles.
