Domestic garbage treatment and cement rotary kiln combined production technology

Flue gas higher than 850 deg.C generated by burning household garbage in incinerator is led into device of revolving kiln in cement dry process for warming-up and predecomposing raw material. Quantity of heat in flue gas is as an auxiliary heat source. Purifying treatment is carried out for flue gas by using warming-up and predecomposing device, humidifying tower and dust catcher. Hot air exhausted from cooling machine for cement grog is utilized to dry garbage entering into factory. Waste residue of burnt garbage is as material to be mixed into cement grog. The invention reaches purposes of saving energy, increasing production as well as reduces quantity of garbage, turns garbage to resources or innoxious thing.
