Description

Technical field: [0001] The invention relates to the technical field of tail gas treatment, in particular to a high-efficiency tail gas treatment device for recycling and processing waste mobile phones. Background technique: [0002] Waste mobile phones are mainly composed of plastic shells, lithium batteries, circuit boards, displays and other parts. These parts contain toxic and harmful substances such as lead, chromium, mercury, etc. If they are not disposed of properly or discarded at will, they will seriously pollute the soil and groundwater, and pose a huge threat to human health. Waste circuit boards also contain brominated flame retardants such as polybrominated biphenyls and polybrominated diphenyl ethers, which are carcinogenic, teratogenic, and mutagenic. Plastic can also produce harmful gases during combustion. Waste mobile phones contain a small amount of valuable metals, especially precious metals, which have reuse value. According to a study, in theory, 0.4...
