System and method for co-processing waste liquid and household garbage incineration fly ash in cement kiln
The invention provides a system and a method for co-processing waste liquid and household garbage incineration fly ash in a cement kiln. The method comprises the following steps: modifying the household garbage incineration fly ash by using a small amount of quick lime, mixing with waste hydrochloric acid, waste emulsion and the like, reacting, and separating to obtain high-added-value materials such as organic aggregate, fine powder, high-calorific-value waste oil, superfine calcium carbonate, ammonium chloride crystals, carnallite and the like. Meanwhile, the process is coupled with a cement clinker production line, and partial material absorption is realized by utilizing the characteristics that a flue gas system of the cement production line contains waste heat, a sintering system needs to supplement heat and a raw material batching station system needs to supplement water. The system and the method have the characteristics that the industrial solid waste is treated in a manner of treating waste with waste, various products with additional values are produced in the whole process, the waste heat of the cement kiln is recycled, carbon dioxide supplementation of a cement line can be realized, and the system and the method have a wide prospect in the hazardous waste utilization and treatment industry.
本发明提供了一种水泥窑协同处置废液及生活垃圾焚烧飞灰的系统及方法。生活垃圾焚烧飞灰用少量生石灰进行改性后，与废盐酸、废乳化液等混合、反应，进行分离，得到含有机质骨料、细粉料、高热值废油、超细碳酸钙、氯化铵晶体、杂盐等高附加值物料。同时，所述过程与水泥熟料生产线相耦合，利用水泥生产线烟气系统含有废热、烧成系统需补热及生料配料站系统需补水特点，实现部分物料消纳。本发明所述系统及方法的特点是采用“以废治废”的方式处理处置工业固废，全套流程中产出多种具有附加值的产物，并对水泥窑废热进行回收，且可实现水泥线二氧化碳补集，在危废利用处置行业具有广阔的前景。
