the cleaning ring (28) is attached to the inner wall of the vacuum tank (2), and the specification of the cleaning ring (28) is matched with the internal structure of the vacuum tank (2);

the cleaning ring (28) is movably connected with the inner wall of the vacuum tank (2) through two pneumatic telescopic rods (27), and when the cleaning ring (28) is driven by the pneumatic telescopic rods (27) to move to the bottom of the vacuum tank (2), the two telescopic rods (31) contract under the action of a spring (32);

the water introduced from the first filter (11) flows to a water inlet pipe (19) from a water feeding port (12), and is guided to a conveying pipe (21) by the water inlet pipe (19) and then is introduced into a steam-water separator (4);

the gas extracted from the extraction opening (7) flows to a conveying pipe (21) from an air inlet pipe (18) and then is guided into the steam-water separator (4) through the conveying pipe (21);

the water separated by the steam-water separator (4) is guided to the water inlet (6) from the water outlet (24) and flows into the vacuum tank (2), one part of the water separated by the steam-water separator (4) is guided into the vacuum pump (5) from the connecting pipe (20), and the other part of the water is discharged from the exhaust pipe (23);

the side walls of the tops of the vacuum tank (2) and the pressure regulator (15) are respectively connected with a pressure gauge (25);

the method comprises the following steps: firstly, water is sent to the inside of a vacuum tank (2), the vacuum tank (2) is subjected to vacuum treatment, the water is sent to the inside of a first filter (11), the water flows to a water sending port (12) after being filtered by the first filter (11), the water flows to a water inlet pipe (19) along a pipeline through the water sending port (12), the water is guided to a conveying pipe (21) through the water inlet pipe (19) and then is guided into a steam-water separator (4), the water separated by the steam-water separator (4) is guided to a water inlet (6) through a water discharging port (24) and then flows into the inside of the vacuum tank (2), one part of gas separated by the steam-water separator (4) is guided into a vacuum pump (5) through a connecting pipe (20), the other part of gas is discharged from an exhaust pipe (23), the water feeding is stopped after the water feeding of the vacuum tank (2) is finished, at the moment, the vacuum pump (5) is started, and the gas in the vacuum tank, the water flows into the steam-water separator (4) along the conveying pipe (21) through the air inlet pipe (18), the water separated by the steam-water separator (4) flows into the vacuum tank (2) after being guided to the water inlet (6) from the water discharge port (24), one part of the gas separated by the steam-water separator (4) is guided into the vacuum pump (5) from the connecting pipe (20), and the other part of the gas is discharged from the exhaust pipe (23) until the inside of the vacuum tank (2) is vacuumized, and then the vacuum water diversion unit can be used for diverting water;

step two: in the water diversion process, a vacuum pump (5) is used for assisting water diversion, water in the vacuum tank (2) is pumped out by a water pump (3), a pressure regulator (15) regulates water pressure in the water pumping process of the water pump (3), the water is discharged from a water outlet valve (16), the water pump (3) continuously pumps water in the vacuum tank (2) in the water pumping process, water entering the vacuum tank (2) is guided to a vacuum assembly from a first filter (11) for water-vapor separation treatment, and then water without gas is guided into the vacuum tank (2) along a water outlet (24) for recycling;

step three: finally, when the interior of the vacuum tank (2) needs to be cleaned, the blow-down valve (10) is opened, the air pump (26) is used for driving the pneumatic telescopic rod (27) to stretch and retract so as to drive the cleaning ring (28) to move up and down on the inner wall of the vacuum tank (2) to clean the inner wall of the vacuum tank (2), and the cleaned dirt is discharged from the blow-down valve (10).
