Polycarbonate reaction tail gas organic phase recovery system

The utility model relates to a chemical tail gas treatment technology, in particular to a polycarbonate reaction tail gas organic phase recovery system which comprises a polymerization reactor, a flash tank, a heat exchanger, an alkali breaking tower, a water scrubber, a vertical shell-and-tube heat exchanger, a washing water storage tank, a resin adsorption system, a condenser, a phase separator and an organic phase storage tank which are sequentially arranged, and the organic phase storage tank is pumped to the polymerization reactor and the flash tank respectively. The system can reduce the loss amount of the low-boiling-point organic solvent and the emission amount of volatile organic compounds. 本实用新型涉及化工尾气处理技术，具体是一种聚碳酸酯反应尾气有机相回收系统，包括依次设置的聚合反应器、闪蒸罐、换热器、碱破塔、水洗塔、立式列管换热器、洗涤水储罐、树脂吸附系统、冷凝器、相分离器和有机相储罐，所述有机相储罐泵送分别至聚合反应器和闪蒸罐。该系统能够降低低沸点有机溶剂的损耗量和挥发性有机物的排放量。
