High-efficiency pyrolysis apparatus

A high-efficiency pyrolysis apparatus, comprising

• a first pyrolysis furnace, including a first chamber and a first heater arranged inside the first chamber, selected from the group including resistance heaters, inductive heaters and electron-beam heaters, generating a first heating temperature of 100-2000° C. in the first chamber to pyrolyze a solid-state waste;
• a second pyrolysis furnace, interconnecting with the first pyrolysis furnace through a first channel, including a second chamber and a second heater arranged inside the second chamber, selected from the group including resistance heaters, inductive heaters and electron-beam heaters, generating a second heating temperature of 100-2000° C. in the second chamber to generate a fluid, wherein the second heating temperature is higher than the first heating temperature;
• a fractional distillation device, interconnecting with the second pyrolysis furnace through a second channel, wherein the fluid is transferred to the fractional distillation device for a separation operation, and wherein a specified portion of the fluid is separated and recycled;
• and
• an air sucking device, interconnecting with the first pyrolysis furnace and generating a negative pressure to the first channel and the second channel to prevent from that air exists in the first pyrolysis furnace and the second pyrolysis furnace and that toxic materials are generated in the first pyrolysis furnace and the second pyrolysis furnace.
