| titleOfInvention | A method for co-processing inorganic hazardous waste in cement kilns |
| abstract | The invention relates to the field of environmental protection, in particular to a method for co-processing inorganic hazardous waste in cement kilns; the invention provides a method for co-processing inorganic hazardous waste in cement kilns. The method not only saves energy consumption, but also can effectively reduce the sulfur content of the solid slag; the invention provides an inorganic cementing solidifying material as a solidifying agent for heavy metals in the solid slag, and the main component of the material is a potassium-magnesium sulfate cementing and solidifying material, It has a good solidification and stabilization effect on various heavy metal elements, and can effectively reduce the heavy metal precipitation rate in the solid slag; the invention utilizes the inorganic hazardous waste as a resource, turning waste into treasure, and the invention utilizes the hot air at the kiln tail to remove the inorganic hazardous waste. The drying treatment is beneficial to improve energy utilization efficiency, simplify equipment, and save energy. The final product of the present invention is cement, no secondary residue is produced, no fly ash is produced, and there is no environmental protection discharge pressure. |
