[0028] Among them, the liquid outlet device of the ion exchange tower, through the arrangement of the main air pipe 3 on the wire winding tube 2, can utilize the main air pipe 3 to input air flow into the inner cavity of the tower body 1 through the wire winding tube 2, and output arc-shaped and outward-flashing airflow from the air groove 22 and the exhaust port 334 to wash away the blockages entangled on the wire winding tube 2, and the annular bubble disturbance output outward by the wind seat 33 disturbs the resin around the end of the wire winding tube 2, causing the resin layer to surge, and the broken resin and light blockages move to the top of the resin layer with the surge, and make the resin particles surrounding the solution outlet wire winding tube 2 larger in size, avoiding blockage, and solving the problem that the existing direct current airflow has limited impact effect on impurities at the outer end of the wire winding tube 2 and poor interference effect on it, thereby affecting the anti-blockage situation.

[0029] Example 2:

[0030] Twenty to thirty groups of air guide vanes 332 are arranged between the end plate 331 and the baffle 34, and an exhaust port 334 located between the outer ends of adjacent air guide vanes 332 is opened on the outer wall of the enclosure 333; wherein, the setting of the air guide vanes 332 can make the airflow output outward between them into an arc shape, thereby increasing the disturbance effect on external impurities and further increasing the anti-blocking effect.
