Geopolymer prepared from waste incineration fly ash bottom slag and system process method
The invention discloses a geopolymer prepared from waste incineration fly ash bottom slag and a system process method, the geopolymer prepared from the waste incineration fly ash bottom slag is prepared from the following raw materials in percentage: 20-60% of fly ash bottom slag and 60-20% of fly ash; 17% of mineral powder; 3% of gypsum; 0.8% of sodium hydroxide; 2% of water glass; the invention relates to the technical field of dangerous solid waste treatment, the fly ash bottom slag cleaning, purifying and purifying technology is adopted, according to the garbage incineration amount of 800 tons per day, 800 * 25% is equal to 200 tons per day of bottom slag, 800 * 4% is equal to 32 tons per day of fly ash, and three slag tanks are designed. The 1 # slag pool and the 2 # slag pool operate alternately, mixed water generated by cleaning enters the 3 # pool and then enters the low-temperature evaporation separator, and water and chlorine separation is carried out. Purified water is circulated to the bottom slag through a pump and is continuously provided for cleaning the bottom slag, and the separated finished chlorine product is prepared into products such as a disinfectant, so that the discontinuous production process of lime water soaking is reduced.
本发明公开了一种垃圾焚烧飞灰底渣制作的地聚物及系统工艺方法，包括利用垃圾焚烧飞灰底渣制作的地聚物，所述利用垃圾焚烧飞灰底渣制作的地聚物按以下百分比的原料组成：飞灰底渣20~60％、粉煤灰60~20％；矿粉17%；石膏3%；氢氧化钠0.8%；水玻璃2%；水胶比0.3%~0.5%，本发明涉及危险固体废弃物治理技术领域,本发明采用的是飞灰底渣清洗、净化、提纯技术,以800吨/天垃圾焚烧量计算：800*25%=200吨/天底渣，800*4%=32吨/天飞灰，设计三个渣池。1#渣池和2#渣池交替运转，清洗所产生的混合水，进入3#池后入低温蒸发分离器，进行水、氯分离。净化后的水用泵循环至底渣处，继续提供给底渣清洗，所分离出的成品氯，制成消毒剂等产品，减少了石灰水浸泡的间断生产工序。
