The working principle of the application is as follows:
the water discharged from the plurality of closed dehydrators 2 is conveyed to the water collecting tank 4 through the pipeline 3, when the liquid level of the water collecting tank 4 rises, the floating disc 8 rises, the gas in the water collecting tank 4 enters the air bag 12, and the air bag is added at the breathing port to be used as a buffer, so that no gas is volatilized into the air.
The variable frequency sewage pump 31 is started to pump away the water in the water collecting tank 4 and send the water to the sewage treatment. The closed dehydration control system provides the flow for controlling the sewage pump 31, controls the floating plate 8 at a stable height, stabilizes the height control of the floating plate, and reduces the distance of the up-down movement of the floating plate: the breathing quantity of the gas discharge port is reduced, and the discharge of toxic and harmful gases is reduced.
When the floating plate 8 rises, the gas in the water collecting tank 4 enters the air bag 12; when the floating plate 8 descends, the air in the air bag 12 is supplemented to the water collecting tank 4, and the air bag 12 is used for buffering to ensure that no air is volatilized into the air.
The discharge capacity of the sewage pump 31 at the outlet of the water collecting tank 4 is smaller than that of the water inlet of the water collecting tank 4 or when the sewage pump 31 does not work due to reasons, the floating plate floats upwards, the floating plate rises to a certain height, the floating plate 8 rises to a certain height, the heavy hammer 25 is supported, and the exhaust port 20 is automatically closed. During the rising of the floating plate 8, the pressure in the upper part of the floating plate 8 in the water collecting tank 4 will gradually increase. When the pressure is increased to be equal to the pressure of the oil tank 1, the floating plate 8 stops moving, liquid below the floating plate is prevented from overflowing to the exhaust port through the floating plate, and safety is guaranteed. The pressure sensor 30 and the magnetic flap level gauge 14 will detect a value outside the set range and the system will alarm and shut off the inlet valve 5 of the water collection tank 4.
Because the gas is too much in the water collecting tank 4, when the floating plate 8 cannot rise to the set height, the system starts the booster pump 29 to convey the gas to the dirty oil pipe 17, the dirty oil pipe 17 is also provided with a dirty oil pump 33, and the dirty oil pump 33 is conveyed away along with the dirty oil.
When the water displacement is larger than the downstream sewage treatment capacity, the closed dehydration control system can adjust the dehydration sequence of the oil tank 1 according to the production condition, suspend partial dehydrators, reduce the sewage discharge capacity, and can dehydrate the dehydrators in time-sharing and batch according to the dehydration severity of each tank, control the total dehydration amount in an allowable range, and avoid impacting the sewage treatment.
