| Abstract: |
| A new incinerator of waste printed circuit boards, U-shape High-temperature Reclamation Incinerator where the organic powder is combusted in swirl-flow mode in high temperature, the metal is smelted and the slag is formed and impoverished efficiently, and the toxic flue gas is oxidized enough in swirl-flow mode in high temperature, has been put forward. The incinerator is of U-shape structure, composed of combustion tower, smelting pool and disinfection tower, and integrates the technology advantages of multiple hearth furnace, reverberatory furnace, cyclone furnace and flash smelting furnace. There is thrice swirl-flow combustion and high-temperature incineration inside the incinerator. The incinerator has the advantage of high metallic recovery rate, no Tetrachlorodibenzo-p-dioxin precursor in the flue outlet of incinerator and self heating smelting. |
