Cyclone type plasma melting furnace, melting treatment system and working method of melting treatment system

The invention discloses a cyclone type plasma melting furnace, a melting treatment system and a working method of the melting treatment system. The cyclone type plasma melting furnace comprises a melting furnace body, a feeding hole, a discharging channel, a discharging smoke outlet and a plurality of plasma generators, wherein the feeding hole is formed in the melting furnace body and communicates with a hearth in the melting furnace body; the discharging smoke outlet is formed in the melting furnace body, and the discharging channel is arranged in the melting furnace body and connected between the hearth and the discharging smoke outlet; the multiple plasma generators are arranged on the melting furnace body at intervals in the circumferential direction of the melting furnace body and communicate with the hearth, so that annular plasma flame flow is formed in the hearth. According to the cyclone type plasma melting furnace, plasma flame rotational flow is adopted to form the annular plasma flame flow, heati
