High viscosity material odor treatment process and catalyst manufacturing method using the electric dust collector and a catalyst ozone process

摘要

The present invention relates to an exhaust gas recirculation system for an exhaust gas recirculation system for an exhaust gas recirculation system for an exhaust gas recirculation system, An electric dust collector for recovering oil mist and organic solvents by an electric dust collection method by a corona discharge, and a residual odor remover for removing residual odor remaining in the exhaust gas separated from the oil mist and the organic solvent due to the electrostatic precipitator through the catalyst ozone And a discharging means for discharging the exhaust gas from which the odor has been removed by the residual odor removing means to the outside by using a blower, and a process for treating the high viscous odor material using catalytic ozone oxidation, A first step of moving the exhaust gas to a heat exchanger; A second step of allowing the heat exchanger to cool the exhaust gas that is moved from the inlet pipe and flows in; A third step of recovering the oil mist and the organic solvents contained in the exhaust gas cooled and moved by the heat exchanger by an electrostatic precipitator; A fourth step of removing the remaining odor remaining in the exhaust gas from which the organic solvents have been recovered by the electrostatic precipitator through the residual odor removing means; And a fifth step of discharging the exhaust gas from which the odor is removed by the residual odor removing means to the outside through the discharging means. Further, the present invention provides a method for preparing a catalyst for removing residual odor in a process for treating a high-viscous odorous substance using the above-described electrostatic precipitator and catalytic ozone oxidation, comprising the steps of: dissolving potassium permanganate (KMnO ₄ ) in water at 50 ° C; It was dissolved in ammonium bicarbonate (NH ₄ HCO ₃₎ in the melting stage water temperature raising step of raising the temperature to 65 ℃; A precipitate first precipitate forming step of forming a precipitate of manganese dioxide (MnO ₂ ) in the water in which potassium permanganate (KMnO ₄ ) and ammonium bicarbonate (NH ₄ HCO ₃ ) are dissolved; Cooling the precipitated manganese dioxide (MnO ₂ ) to room temperature; Adjusting the pH of the aqueous solution to 3 using sulfuric acid (H ₂ SO ₄ ) to remove the ammonia of the precipitated manganese dioxide (MnO ₂ ) by the cooling step; Forming a precipitate of Cu (OH) ₂ CuCO ₃ by adding a copper sulfate (II) acetic acid (CuSO _{4 - 5} H ₂ O) and ammonium bicarbonate (NH ₄ HCO ₃ ) after the adjustment; Rinsing several times with distilled water to remove SO ₄^2- remaining in the Cu (OH) ₂ CuCO ₃ precipitate; Drying the Cu (OH) ₂ CuCO ₃ precipitate after the step of rinsing (S700), and molding the pellet into a pellet of a predetermined size by a pressure molding extruder.
