A trapezoidal ring 5 is fixedly connected to the side of the bottom end of the annular fan 4 away from the first shell 2. The bottom end of the trapezoidal ring 5 is fixedly connected to the second shell 19. An air guide block 17 is fixedly connected to the top inner wall of the second shell 19. The air guide block 17 is used to guide these airflows to effectively enter the packing tower so that the gas can be evenly distributed in the tower. The application of the annular fan 4 and the air guide block 17 can effectively improve the air intake efficiency. The annular fan 4 can provide a larger airflow. At the same time, the air guide block 17 can effectively guide the airflow into the packing tower, thereby improving the air intake efficiency, accelerating the gas-liquid separation process, and improving work efficiency.

Finally, the demister block 9 removes the liquid droplets in the gas flow, and the gas after gas-liquid separation is discharged through the exhaust port 1, while the liquid flows out through the outlet pipe 15 and flows into the water storage tank 14. The valve 16 can adjust the water outlet speed and flow rate to ensure the stable operation of the system.
