During the printing of shoe upper trademarks, organic waste gases are generated by ink volatilization; waste gases are generated by the high-frequency pressing process of shoe upper materials; solvent-based paints are generally used in the sole painting process; sole and midsole lamination, upper and sole gluing The adhesive used in the molding process; the foaming process of shoe sole materials EVA and MD; the organic waste gas generated under the heating conditions of TPR and PVC injection molding; these processes will produce organic waste gas. Shoemaking exhaust gas VOC → Pretreatment equipment (dust particle removal and filtration, atomization spray tower, water vapor separation and other equipment) → Low-temperature plasma decomposition exhaust gas purifier/UV light deodorization photocatalyst catalytic exhaust gas purifier/Plasma UV light deodorization exhaust gas purification Device → High Discharge; Shandong Haowei Environmental Protection Editor’s answer.
