WASTE INCINERATION FLY ASH DEACIDIFYING AND CHELATING AGENT AND PREPARATION METHOD THEREFOR

摘要

A waste incineration fly ash deacidifying and chelating agent having deacidifying and chelating functions. The contents of the components of the agent by weight are: 20-30% of sodium bicarbonate, 20-30% of hydrated lime, 5-10% of magnesium chloride, 15-25% of magnesium oxide, 1-3% of monocalcium phosphate, 5-10% of calcium sulfate, and 3-5% of sodium sulfide. Also provided is a method for preparing a waste incineration fly ash deacidifying and chelating agent having deacidifying and chelating functions. The agent has deacidifying and chelating functions, and can integrate, in a process, smoke deacidifying and fly ash chelating which need to be carried out in two processes in existing waste incineration power plants, so as to effectively reduce operating costs of the waste incineration power plants.
