摘要：A multi-cyclone separator was provided with combination of venturis and cyclones. The gas-liquid co-current and countercurrent modes of the multi-cyclone separator were proposed. The two modes can be converted by adjusting the gas channels. The countercurrent mode was achieved when the liquid flow ranged from 7.5 to 17.5 L min-1. For countercurrent mode, larger liquid flow is benefit for improving the gas circulation flow. There is a reasonable injected gas flow that makes the gas circulation flow reach peak value. There is a critical injection gas flow beyond which countercurrent cannot occur. In the limited range of gas-liquid countercurrent, the volumetric mass transfer coefficient and separation efficiency in countercurrent mode are better than that of co-current mode. When the injected gas flow is larger than the critical value, only the third stage mass transfer unit works as the performance of countercurrent mode will decrease sharply.
