The invention provides a semi-dry garbage incineration flue gas purifying treatment method and a system device thereof, flue gas enters a spray tower from a waste heat boiler, activated carbon is injected into a horizontal inlet flue to remove dioxin and heavy metals in the flue gas; the flue gas is simultaneously carried out the reaction with a high specific surface area alkaline neutralizer, most of the harmful substances in the flue gas are purified by generating chemical reactions with the alkaline neutralizer; when the flue gas passes through a filter layer which is formed by granule materials in a bag dust collector, gaseous pollutants can still be reacted with non-reacted lime and activated carbon in the filter layer to be further purified. The system device can lead the flue gas and the high specific surface area lime emulsion to achieve the best contact area, thus ensuring the best flue gas retention time, achieving the full heat transfer and the chemical and heat transfer process; furthermore, the spray is even, the anti-blockage and the anti-corrosion performances are better; a lime emulsion preparation device can automatically control and prepare the concentration and the using amount of the emulsion to be participated in the reaction according the content of wastes in the ingredients of the flue gas and the temperature of the flue gas; the usage and the regulationof the neutralizer are flexible. The system device further has the advantages of low investment cost, strong load adaptability and no waste water discharge, etc.
