摘要： A gas-liquid separation device comprises: an outer housing extending vertically, which is provided with a gas outlet at an upper end of the outer housing and a liquid outlet at a lower end of the outer housing; an inner housing disposed in the outer housing and extending vertically, an upper end of the inner housing being coupled to the outer housing in a sealed manner, a lower end of the inner housing being opened, with an annular space formed between the outer housing and the inner housing; a feeding tube inserted into the outer housing and communicated with the inner housing, with a cyclone mechanism between the feeding tube and the inner housing to output fluid into the inner housing as a swirling flow. The present disclosure can reduce the disturbance of the downward gas flow and the upward gas flow in the separation space, thus improving the separation efficiency.
