Document Type and Number:
WIPO Patent Application WO/2022/160319
Kind Code:
A1
Abstract:
A filtering system, an air-conditioning system, a data center, and a cleaning method for a filtering system. The filtering system comprises an overall liquid inlet (1), an overall liquid outlet (2), a first Y-shaped filter (3), and a second Y-shaped filter (4); the first Y-shaped filter (3) comprises a first liquid flow port (31), a second liquid flow port (32), and a first drainage outlet (33); the first liquid flow port (31) is connected to the overall liquid inlet (1) by means of a first pipeline (G1); the second liquid flow port (32) is connected to the overall liquid outlet (2) by means of a second pipeline (G2); the first drainage outlet (33) is connected to a first waste liquid region by means of a third pipeline (G3); the second Y-shaped filter (4) comprises a third liquid flow port (41), a fourth liquid flow port (42), and a second drainage outlet (43); the third liquid flow port (41) is connected to the overall liquid inlet (1) by means of a fourth pipeline (G4); the fourth liquid flow port (42) is connected to the overall liquid outlet (2) by means of a fifth pipeline (G5); and the second drainage port (43) is connected to a second waste liquid region by means of a sixth pipeline (G6). The foregoing pipelines are respectively provided with switch valves, and by selecting the opening and closing of the switch valves, the specific working state of the filtering system can be designed, and the filters are cleaned without stopping the filters.
