The invention discloses an eddy current self-heating nitrogen replacement and detoxification device for dioxin-containing fly ash. The eddy current self-heating nitrogen replacement and detoxification device is characterized by comprising a kiln body, wherein the kiln body is of a hollow structure and is of a three-section structure comprising a preheating section, a heating section and a cooling section; an inductance heating device wraps the heating section; at least one nitrogen channel is arranged in the kiln body in a penetrating manner; the conveying direction of the nitrogen channel is the cooling section, the heating section and the preheating section; waste gas is discharged through an exhaust port of the preheating section; a plurality of exhaust holes are formed in the part, passing through the heating section, of the nitrogen channel; and nitrogen is discharged through the exhaust holes and then reacts with the dioxin-containing fly ash. According to the eddy current self-heating nitrogen replacement and detoxification device, the energy-saving effect is improved through the sectional structure and the counter-current design, and the fly ash is subjected to a scouring reaction through the nitrogen channel, so that the reaction completeness is improved.
