Method for removing dioxin in waste incineration flue gas and equipment thereof

The invention discloses a method for removing dioxin in waste incineration flue gas, which comprises the following steps of: a) first adopting a combined process of a Venturi jet and a dry dust collector to remove the dioxin; b) then adopting filtration equipment to remove the dioxin; c) allowing granular activated carbon absorbing the dioxin to be discharged through the bottom of the filtration equipment and enter a crushing machine to be crushed into powdery activated carbon; d) supplying the powdery activated carbon to the Venturi jet for use; and e) discharging purified waste incinerationflue gas which is output from a flue gas outlet of the filtration equipment into the atmosphere through a chimney. The invention also discloses equipment for implementing the method. The method and the equipment can increase the removal rate of the dioxin and reduce operating cost.
