| titleOfInvention | Device and method for eliminating and recycling organic solvent from cathode electrophoresis emulsion |
| abstract | The invention relates to a device and a method for eliminating and recycling organic solvent from cathode electrophoresis emulsion. The device comprises an upper tower section, a middle tower section and a lower tower section, wherein a carrier gas inlet is formed at the lower part of the lower tower section, the lower end of the lower tower section is connected with a heat exchanger of which the bottom is connected with an emulsion recover kettle, the lower end of a heat exchange tube in the heat exchanger is provided with a cold emulsion feeding hole, the upper end of the heat exchange tube is provided with an emulsion discharge hole, the emulsion discharge hole is communicated with the emulsion feeding hole at the lower end of the middle tower section by a charging pump, the upper end of the upper tower section is connected with a tower top, the tower top is externally connected with a condenser, a reflux ratio controller is arranged on the condenser, the bottom of the condenser is connected with a solvent recovery kettle, and the upper end of the condenser is connected with a vacuum pump. The method comprises the following steps: (1) vacuumizing and introducing water vapor; (2) performing reversed current heat exchange to the cathode electrophoresis emulsion, and then performing gas-liquid mass transfer in a packed tower; and (3) adjusting the reflux ratio controller and collecting emulsion and a solvent. According to the device and the method, the removal rate of organic solvent is high, zero emission is realized, the process control is stable, the operation is simple, and the recovery products have excellent performances. |
