[0043] The buffer baffle 1501 is an arc surface concave towards the fixed plate 14, when the two absorbing liquids impact the buffer baffle 1501, the X-shaped structure is compressed in the front and back directions, the limiting shaft 1507 is extracted from the end portion of the fixed sleeve 1508 by a certain length, and the connecting spring 1509 is lengthened at the same time, the kinetic potential energy of the impact force is converted into the elastic potential energy, and the buffering effect is achieved.

[0051] The opposite end faces of the upper extension plate 1703 and the lower extension plate 1704 are respectively provided with a first gear extension groove 1706 and a second gear extension groove 1713; one side of the first gear extension groove 1706 is provided with a first insertion slot 1707, and the other side is provided with a first fixed slot 1708, the inside of the first fixed slot 1708 is fixedly connected with a first rack 1709 which extends downward; the second gear extension groove 1713 is provided with a second fixed slot 1711 corresponding to the first insertion slot 1707 on one side, the inside of the second fixed slot 1711 is fixedly connected with a second rack 1712 which extends upward, and the other side is provided with a second insertion slot 1710 corresponding to the first rack 1709.

[0052] The rear section of the phase separation tank 1 is penetrated by a rotating shaft 8, and the rotating shaft 8 can be pulled out, one end of the rotating shaft 8 inside the phase separation tank 1 is fixedly connected with a transmission gear 1714, the transmission gear 1714 rotates between the first gear extension groove 1706 and the second gear extension groove 1713, the first rack 1709 and the second rack 1712 are different in position in front of and behind the phase separation tank 1, and there is an overlapping area, by pulling out the rotating shaft 8, the transmission gear 1714 on both sides can be simultaneously meshed with the first rack 1709 and the second rack 1712, or only one of the first rack 1709 and the second rack 1712 is meshed with one side, so that the height adjustment of the upper extension plate 1703 and the lower extension plate 1704 can be simultaneously or individually realized.

[0053] When the upper extension plate 1703 and the lower extension plate 1704 are folded, the second rack 1712 is inserted into the first slot 1707, and the first rack 1709 is inserted into the second slot 1710, realizing the storage of the rack. When the rotating shaft 8 rotates, the upper extension plate 1703 and the lower extension plate 1704 are pushed by the first rack 1709 and the second rack 1712 to move upward and downward respectively, and a certain interval is generated by the movement of the upper extension plate 1703 and the lower extension plate 1704.

[0054] The rotating shaft 8 is fixedly connected with a rotating disc 16 at one end outside the phase separation tank 1, and a limiting tube 6 is further arranged at the rear section of the phase separation tank 1, the limiting tube 6 is sleeved outside the rotating shaft 8, and the limiting tube 6 is provided with a fixed rotating knob 7 for fixing the rotating angle of the rotating shaft 8, which plays a good fixing role and prevents loosening.

[0056] It should be noted that the same or similar parts in this embodiment as in Embodiment One can be mutually referred to, and will not be described in detail in this application.

[0062] Then the two-phase absorbent liquid flows into the curved flow channel from the side of the fixed plate 14 not connected with the phase separation tank 1;
