CFD (computational fluid dynamics)-based deacidifying equipment and method of garbage incineration furnace

The invention relates to CFD (computational fluid dynamics)-based deacidifying equipment of a garbage incineration furnace. The CFD-based deacidifying equipment comprises an incineration furnace, a heat exchange device, a deacidifying device, a CFD simulation unit and a PLC (programmable logic controller) control unit, wherein the flue gas produced in the incineration furnace is sent into the heatexchange device to cool, and the cooled flue gas is sent into the deacidifying device; the CFD simulation unit is used for simulating and computing the concentration of acid gas in the flue gas of the incineration furnace according to the component and load of charged garbage in the incineration furnace, the concentration of acid gas is inputted into the PLC control unit, and the PLC control unitis used for controlling the deacidifying device to spray a deacidifying agent to deacidify the flue gas. The invention also provides a CFD-based deacidifying method of the garbage incineration furnace. The CFD-based deacidify
