Method for preparing carbonized foam geopolymer through cooperation of garbage incinerator bottom slag and garbage incineration fly ash and application of carbonized foam geopolymer
The invention belongs to the field of comprehensive utilization of solid waste resources, and discloses a method for preparing a carbonized foam geopolymer through cooperation of garbage incinerator bottom slag and garbage incineration fly ash and application of the carbonized foam geopolymer. The method comprises the following steps: compounding waste incineration fly ash with a melting aid, melting at high temperature to obtain glass slag, pre-treating the obtained glass slag compounded waste incineration furnace bottom slag, mixing with a foaming agent, an alkali activator and a foam stabilizer, and carrying out activation reaction and foaming reaction under the action of the alkali activator and the foaming agent to obtain the foaming agent. And forming, curing, demolding and carbonizing to obtain the carbonized foam geopolymer. According to the method, waste is treated with waste, waste is turned into wealth, CO2 is captured and utilized at the same time, CO2 is permanently sealed and stored, the method has multiple meanings of recycling, energy conservation and emission reduction, the method is used for preparing foam materials, the method has the advantages of being simple in process, low in cost, high in operability and high in additional value when used for preparing the foam materials, and the problem of recycling and green co-processing of the garbage incinerator bottom slag and the garbage incineration fly ash is solved.
本发明属于固废资源综合利用领域，公开了一种垃圾焚烧炉底渣协同垃圾焚烧飞灰制备碳化泡沫地质聚合物方法及其应用。该方法将垃圾焚烧飞灰复配熔融助剂，经高温熔融后得到玻璃熔渣，得到的玻璃熔渣复配垃圾焚烧炉底渣经预处理后与发泡剂、碱激发剂和稳泡剂混合，在碱性激发剂和发泡剂作用下发生活化反应和起泡反应，经成型、养护、脱模、碳化得到碳化泡沫地质聚合物。本发明实现了“以废治废、变废为宝”，同时捕集与利用CO2，使CO2永久封存，具有资源化和节能减排多重意义，用于制备泡沫材料，具有工艺简单，成本低廉，可操作性强，附加值高的优点，解决了垃圾焚烧炉底渣和垃圾焚烧飞灰资源化绿色协同处置问题。
