A method for purifying exhaust of waste gas using atomized fluid droplets combined with turbulent flow, including the following steps: a). atomizing the absorption or reacting fluids to microsized droplets; b). enabling waste gas to pass through the aforementioned absorption or reacting fluids and creating a turbulent flow to thoroughly react the waste gas with the droplets; c). reacting of harmful substances in the waste gas with droplets of the absorption or reacting fluids; d). implementing demisting treatment of the waste gas flow; e). discharging the treated waste gas. The aforementioned steps of the present invention enable the purification of waste gas without the need for packing, and achieve high removal efficiency and low energy consumption.
