Embodiment 1
[0041] see Figure 1-2 As shown: an embodiment of the present invention specifically discloses a treatment process for resource utilization of copper-containing waste and flue gas purification, including the following steps:
[0042]1) 100. Flue gas purification in the drying process: the flue gas generated when the copper-containing sludge waste is dried,
[0043] The following table shows the output parameters of drying flue gas:
[0044] project unit parameter Remark Wet flue gas flow N m 3 / h
39093 Standard state, wet basis, actual oxygen, Flue gas temperature ℃ 120~150 / H2O (standard state, wet flue gas) Vol% 10~20 soot g / Nm 3
10~20 SO2 mg / Nm 3
48.67 NOx mg / Nm 3
/
[0045] The flue gas purification process route adopted is "dry deacidification of slaked lime + spraying activated carbon + bag dust removal + induced draft fan + chimney";
[0046] The specific further description...

Abstract
The invention belongs to the technical field of flue gas and waste gas purification treatment, and particularly relates to a treatment process for recycling copper-containing waste and purifying flue gas, which comprises the following steps: flue gas purification in a drying process: a flue gas purification process route is slaked lime dry deacidification, activated carbon injection, cloth bag dust removal, an induced draft fan and a chimney; the flue gas purification in the roasting process: the flue gas purification process route comprises gravity settling, slaked lime dry-process deacidification, cloth bag dust removal, induced draft fan, RTO, SCR denitration synergistic catalyst dioxin removal, a GGH plate heat exchanger, limestone, gypsum wet-process deacidification, a booster fan and the chimney; and the flue gas purification in the smelting process: the flue gas purification process route comprises gravity settling, surface cooling, slaked lime dry deacidification, cloth bag dust removal, an induced draft fan, RTO, dioxin removal by a catalyst reaction tower, limestone, gypsum wet deacidification, the booster fan and the chimney. The process provided by the invention achieves the purposes of safe transformation, environmental protection, energy conservation and emission reduction, and has important significance for improving the local ecological environment.
Description
technical field [0001] The invention belongs to the technical field of flue gas waste gas purification and treatment, and in particular relates to a treatment process for resource utilization of copper-containing waste and flue gas purification. Background technique [0002] The industry in Wuxi is developed, and there are many electroplating and electronic industry enterprises, wire and cable enterprises, and a large amount of industrial sludge is produced. Sludge from electroplating and electronics industry enterprises contains a variety of harmful heavy metals, with complex components, involving many types of hazardous substances defined in the "National Hazardous Waste List". The hazard characteristic is toxic, and it is a typical industrial solid hazardous waste. Heavy metals such as copper in sludge migrate along the path of "sludge→soil→crops→human body" under the action of rainwater leaching, endangering human health through the biological chain, and may cause second...
