When the proportion of gas in the mixed liquid is small, the ball valve can be closed by rotating the adjusting rod, thereby closing the air outlet. At this time, the feed port continues to take in liquid. Since the gas cannot circulate and accumulates on the upper layer of the separation layer, the air pressure on the liquid below is continuously increased, which can further accelerate the liquid through the liquid inlet. The utility model is provided with a separation structure, and under the action of the separation structure, the mixed liquid can be quickly separated into gas and liquid, and then the liquid is made to flow out of the device through the liquid accumulation tube, thereby better improving the efficiency of gas-liquid separation. Because the air outlet structure is provided, after closing the ball valve, the air pressure of the gas itself can be used to accelerate the internal liquid circulation, thereby improving the efficiency of gas-liquid separation, which can better meet the needs of users.

[0020] The working principle of the utility model is:

[0021] The utility model relates to a gas-liquid separator for polyether production. The device is assembled and placed at a suitable working place. A mixed liquid is passed into a separation layer 12 through a feed port 4. When the mixed liquid just enters the separation layer 12, it is separated for the first time through a first screen 13, and then some larger bubbles are eliminated and fall into the separation layer 12. Then, due to the heavy liquid, the liquid settles downward, and the gas floats upward. After the liquid is accumulated in the liquid accumulation layer 11 to a certain extent, the liquid generates a certain buoyancy on the float 15, and then the float 15 drives the movable rod 18 to move upward in the through groove 21, and then the liquid inlet 17 is exposed inside the liquid accumulation layer 11. At this time, the liquid passes through the liquid inlet 17 and is collected in the liquid accumulation pipe 9, enters the liquid storage bin 16 through the liquid accumulation pipe 9, and flows out of the device after the liquid outlet 7 is opened. At the same time, due to the continuous rise of the liquid inside the liquid accumulation layer 11, after the movable rod 18 is lifted to a certain height, the clamping block 19 abuts against the liquid. Below the receiving block 10, the lifting is stopped, and while the liquid is circulating, the gas is filtered through the second screen 14 for the second time and then flows out of the device through the air outlet 5. When the proportion of gas in the mixed liquid is small, the ball valve 20 can be closed by rotating the adjusting rod 6, and then the air outlet 5 is closed. At this time, the feed port 4 continues to take in liquid. Since the gas cannot circulate and accumulates on the upper layer of the separation layer 12, the air pressure on the liquid below is continuously increased, which can further accelerate the liquid through the liquid inlet 17. The utility model is provided with a separation structure, and under the action of the separation structure, the mixed liquid can be quickly separated into gas and liquid, and then the liquid is made to flow out of the device through the liquid accumulation tube 9, thereby better improving the efficiency of gas-liquid separation. Because the air outlet structure is provided, after closing the ball valve 20, the air pressure of the gas itself can be used to accelerate the internal liquid circulation, thereby improving the efficiency of gas-liquid separation, which can better meet the needs of users.
