吸附法是一项广泛应用于治理大风量、中低浓度有机废气的浓缩净化技术，具有操作简单、净化效率高的优点。冷凝法是回收高浓度废气极为有效的手段。将吸附浓缩技术与冷凝回收技术进行有效结合，可高效回收中低浓度废气中具有再利用价值的有机溶剂等，实现有机溶剂的资源化回收利用。通过对吸附-冷凝工艺的详细介绍和分析，包括吸附剂和冷媒的选择、结构的优化、工业应用情况等，以期达到回收效率、设备成本及安全性等综合性能的最优化。%The organic solvent which has recycling value in the middle and low concentration waste gas can be effective recovered when the technology of adsorption is integrated with condensation recycling technology, so as to realize the resource recycling of organic solvent. Through the detailed introduction and analysis of the adsorption-condensation technology, includ-ing the choice of the adsorbent and proper refrigerant, the paper expects to achieve the optimization of structure and industrial application, the recovery efifciency, equipment costs and safe operation.
