Efficient and safe garbage cracking gasifier

An efficient and safe garbage cracking gasification furnace is composed of a rotary furnace body, a furnace base, a ball rotating disc, a furnace cover, a high-temperature superconducting heat exchanger, a gas collecting pipe, a liquid sealing sleeve, a cone heat exchanger, an annular heater, a feeding machine, a superconducting waste heat recoverer and a driving device. The device is characterized in that a closed furnace body is connected with a raceway disc on a ball turntable below the furnace body; the furnace base is connected with a ball turntable lower raceway disc above the furnace base; the inner circle edge of the raceway disc is connected with the cone heat exchanger; the multiple high-temperature superconducting heat exchangers are assembled on the cone heat exchanger, the annular heater heats evaporation sections of the high-temperature superconducting heat exchangers through gas generated by the cracking furnace, generated high-temperature radiant heat is rapidly conducted to garbage rotating i
