Solid waste-based binder for sealing and storing carbon dioxide, preparation method and carbon dioxide sealing and storing method thereof
The invention relates to a solid waste-based binder for sealing and storing carbon dioxide, a preparation method of the solid waste-based binder, and a method for sealing and storing carbon dioxide by using the solid waste-based binder. A solid waste material; a functional additive; the preparation method comprises the following steps: heating and extruding the functional additive and part of the solid waste material through a twin-screw extruder, processing to below 400 or 600 meshes through a mechanical pulverizer, and uniformly stirring and mixing with the inorganic cementing material and the like through a multifunctional stirrer to obtain binder powder; the first sealing process comprises the following steps: uniformly mixing binder powder, sand and water through a multifunctional stirrer, preparing a sample (240mm * 115mm * 53mm), and curing the flue gas to seal the carbon dioxide in the flue gas; and the second method comprises the following steps: uniformly mixing and stirring the binder, the aggregate and the water in a sealable stirring tank, introducing the flue gas, continuously stirring for 30-60 minutes, and then directly using the mixture for backfilling of a mine pit, a mine hole, an oil well and a mine so as to seal and store the carbon dioxide in the flue gas.
一种封存二氧化碳用固废基粘结剂、制备方法及其封存二氧化碳方法，该粘结剂按质量份计，包括以下组分：无机胶凝材料；固废材料；功能助剂；制备步骤：将功能助剂和部分固废材料经双螺杆挤出机加热挤出，再经机械粉碎机加工至400或600目以下，再与无机胶凝材料等经多功能搅拌机搅拌混合均匀即得到粘结剂粉体；封存工艺有两种，第一种：使用粘结剂粉体、砂和水经多功能搅拌机混合均匀后制样(240mm×115mm×53mm)、烟气养护即可封存烟气中的二氧化碳；第二种：将粘结剂、骨料和水在可密封搅拌罐中混合搅拌均匀，通入烟气，继续搅拌30min～60min，然后将拌合物直接用于矿坑、矿洞、油井和矿井的回填，即可将烟气中的二氧化碳封存。
