s2: when the pipeline detection device (9) does not detect the liquid passing, the pipeline detection device (9) feeds back to the control component of the current layer, the air source pipeline (5) of the current layer is opened, sterile compressed gas is reversely blown into the filtering device (4) of the current liquid discharge pipeline (3), and if the pipeline detection device (9) still does not detect the liquid passing, the control component of the current layer is closed;
s3: then, a control assembly of the next layer of liquid discharge pipeline (3) is opened to discharge liquid, if the pipeline detection device (9) detects that liquid passes through, the washing liquid is continuously discharged through the current layer of liquid discharge pipeline (3), the steps S2 and S3 are repeated, the steps are sequentially circulated, the next layer of liquid discharge pipeline (3) is gradually communicated, and the washing liquid in the washing tank (1) is discharged until the washing liquid in the washing tank is discharged.
9. The method according to claim 8, wherein in step S2, after the air source pipeline (5) is started to blow sterile compressed air into the filtering device (4) of the current drain pipeline (3) in the reverse direction, if the pipeline detection device (9) detects that the liquid passes through, the washing liquid is continuously discharged through the current drain pipeline (3).
10. The method for discharging the washing liquid of the online washing system according to claim 8 or 9, wherein the discharging end of the liquid discharging pipeline (3) is further provided with a liquid sealing device (8), a liquid level switch is arranged in the liquid sealing device (8), and in the liquid discharging process, when the liquid level switch detects that the liquid in the liquid sealing device (8) is higher than a set position, the liquid level switch detects that an opening signal is sent to a liquid discharging valve (82) of the liquid sealing device (8), and the washing liquid is discharged from the liquid sealing device (8);
when the liquid level switch detects that the liquid in the liquid sealing device (8) reaches a set position, the liquid level switch detects that a closing signal is sent to a liquid discharge valve (82) of the liquid sealing device (8).
