Abstract

The invention discloses a circuit board incineration smelting furnace and a circuit board incineration smelting method adopting the circuit board incineration smelting furnace. The circuit board incineration smelting furnace comprises a main furnace body arranged vertically and a reversal combustion tower. The main furnace body is provided with a charging port, a waste material combustion chambercommunicating with the charging port, a smelting chamber located below the waste material combustion chamber, a boiling combustion chamber located above the waste material combustion chamber and a smoke collection hood located above the boiling combustion chamber. The reversal combustion tower communicates with the smoke collection hood. A smoke dust settling chamber is arranged below the reversalcombustion tower. A pneumatic carrier pipe communicates between the boiling combustion chamber and the smoke dust settling chamber. The lower side of the smoke dust settling chamber is further provided with a Venturi feed pipe. By means of the technical scheme, the utilization rate of thermal energy is increased, emissions of poisonous and harmful gas are reduced, and the combustion efficiency ishigh; the early-period treatment cost is reduced, energy is saved by 50%, consumption of refractory materials such as refractory bricks is reduced, and the service cycle of the furnace is prolonged.

Description

Technical field [0001] The invention relates to a circuit board incineration smelting furnace and a circuit board incineration smelting method, belonging to the technical field of circuit board recycling. Background technique [0002] With the acceleration of the update of electronic products, the number of discarded printed circuit boards (PCBs), the main component of electronic waste, is also increasing. The environmental pollution caused by waste PCBs has also aroused the attention of various countries. In waste PCBs, heavy metals such as lead, mercury, and hexavalent chromium, as well as toxic chemicals such as polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE), which are used as flame retardant components, are contained in the natural environment. Groundwater and soil cause huge pollution, which brings great harm to people's lives and physical and mental health. On the waste PCB, there are nearly 20 kinds of non-ferrous metals and rare metals, which h...
