The typical hazardous waste incineration ash and slag inductance melting treatment system according to claim 1, wherein a plug-in water tank is externally hung on the constant temperature water-cooled slag extractor, and a cold slag cold water inlet is arranged at a position of the constant temperature water-cooled slag extractor close to a slag and metal liquid chute; the cold slag cold water inlet is connected with a cold water source, the external water tank is communicated with the inside of the constant temperature water-cooling slag extractor, and a cold slag hot water outlet is formed in the external water tank.
11. The system for melting and treating typical hazardous waste incineration ash and slag inductance according to claim 10, wherein the external water tank and the constant temperature water-cooling slag extractor share an outer wall, and the top of the outer wall is opened, so that water in the constant temperature water-cooling slag extractor overflows into the external water tank directly, and the liquid level in the external water tank is always consistent with the liquid level of the constant temperature water-cooling slag extractor.
12. The typical hazardous waste incineration ash and slag induction melting treatment system according to claim 11, wherein the cold slag cold water discharge port is arranged in the middle of the externally hung water tank, so that the phenomenon of empty pumping of the circulating water pump is avoided.
