Description

Technical Field

[0001] The utility model relates to the technical field of fly ash pretreatment, and more specifically, to a fly ash pH control device. Background Art

[0002] A large amount of fly ash is generated during the incineration of domestic waste. The main chemical components of fly ash from waste incineration are CaO, SiO2, Al2O3, Fe2O3, SO3, NaCl, KCl, Na2O, and K2O. Fly ash is enriched with highly toxic dioxins (PCDD / Fs) and heavy metals. Fly ash pickling is a common fly ash pretreatment method. The heavy metal content in fly ash can be significantly reduced after pickling. In order to ensure that heavy metals can be removed efficiently and to avoid a large amount of fly ash being dissolved into the liquid phase, the pH of the pickling process needs to be controlled. However, the existing equipment cannot detect the pH value of the fly ash pickling solution in real time, and thus cannot regulate the pH of the pickling process in real time, resulting in a relatively extensive pickling process and the inability to accurately control the pickling effect.
