Preparation method of waste gas foaming cemented filling material
The invention relates to the technical field of mine filling materials, and particularly provides a preparation method of a waste gas foaming cemented filling material, the preparation method comprises the following steps: mixing solid waste, a cementing agent, water, an additive and a foam stabilizer to prepare slurry; foaming the waste gas to be treated to prepare foam; mixing the slurry with the foam to prepare the waste gas foaming cemented filling material, so that reacted gas in the waste gas to be treated is partially cured in the waste gas foaming cemented filling material; and the unreacted gas part in the waste gas to be treated is sealed in the pores of the waste gas foaming cemented filling material. With such a configuration, it is possible to directly treat the exhaust gas by means of the exhaust gas foamed cemented filling material. Due to the fact that waste gas containing CO2 under the scene of power plant flue gas and the like can be directly treated without purification, the capture and purification cost of single gas is saved, and a new thought is provided for the scene of on-site foaming filling treatment of coal mine pithead power plant flue gas and the like.
本发明涉及矿山充填材料技术领域，具体提供了一种废气发泡胶结充填材料的制备方法，所述制备方法包括：将固体废弃物、胶结剂、水、外加剂和稳泡剂混合，制得料浆；将待处理的废气发泡，制得泡沫；将所述料浆与所述泡沫混合，制得废气发泡胶结充填材料，以便：待处理的废气中已反应的气体部分固化在所述废气发泡胶结充填材料中；以及待处理的废气中未反应的气体部分封存在废气发泡胶结充填材料的孔隙中。通过这样的构成，能够谋求通过废气发泡胶结充填材料对废气进行直接处理。由于无需提纯便可直接处理包含CO2的电厂烟气等场景下的废气，节省了单一气体的捕获与提纯成本，并因此为煤矿坑口电厂烟气的就地发泡充填处理等场景提供了新思路。
