Abstract

The invention provides a method and a device for co-processing regenerated gelled composite particles and carbon dioxide-containing industrial waste gas, and belongs to the technical field of resourceutilization. The method comprises the following steps: mixing a microbial dispersion liquid, an oxygen release agent and an in-situ induced deposition composite medium to obtain a microbial oxygen release in-situ induced deposition composite medium, wherein the in-situ induced deposition composite medium is obtained by mixing potassium acetate, ammonium nitrate, calcium nitrate and water; puttingthe regenerated gelled composite particles into a treatment bin, and introducing carbon dioxide-containing industrial waste gas into the treatment bin for carbonization pretreatment under the condition that the relative humidity in the treatment bin is not lower than 90%, so as to obtain a carbonization pretreatment material; spraying the microorganism oxygen release in-situ induction depositioncomposite medium into a treatment bin containing a carbonization pretreatment material for microorganism enhancement treatment, so as to obtain enhanced regenerated cementing composite material particles. The method provided by the invention can realize reinforcement treatment of the regenerated gelled composite material particles and purification treatment of industrial waste gas.

Description

technical field [0001] The invention relates to the technical field of resource utilization, in particular to a method and device for co-processing recycled gelled composite material particles and industrial waste gas containing carbon dioxide. Background technique [0002] Regenerated cementitious composite material 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, resulting in the use of recycled cementitious composite material particles as aggregate or Compared with ordinary cementitious composite materials prepared by using quartz sand and stones as aggregates, the cementitious composite materials prepared by the mixture have different degrees of reduction in impermeability and mechanical properties, and the quality is unstable. The utilization rate of recycled cementitious composite particles is low. [0003] Industrial waste gas refers to the general term...
