The beneficial effects produced by adopting the scheme are as follows: the inlet tube, outlet pipe and play oil pipe all are fixed connection with the oil distribution tank, and the oil removal pipe is vertical to be set up in the oil distribution tank, and the gas phase balance pipe that the oil distribution tank top set up communicates with external gas phase balance device, guarantees that every atmospheric pressure that divides in the oil distribution tank equals with the ordinary pressure, and the device's use is as follows: the waste oily wastewater is discharged into an oil separating tank through a water inlet pipe, the water level of the oily wastewater in the oil separating tank is gradually increased, oil and water are separated into layers due to the fact that the specific gravity of the oil is smaller than that of the water, when the oily wastewater in the oil separating tank is gradually increased, the water body on the lower layer enters an oil separating pipe, the water level of the oil separating tank is equal to that of the oil separating pipe, when the oily wastewater is gradually increased to a water outlet pipe, the water body on the lower layer is discharged out of a first oil tank stage through the oil separating pipe and is discharged into a next oil separating tank, the oil body on the upper layer is discharged out through an oil outlet pipe and is collected, and the purpose of oil-water separation of the oily wastewater is achieved; because the water inlet pipe on the oil separating tank is gradually lowered, the water in the upper oil separating tank can be discharged into the lower oil separating tank without the action of external force, thereby saving energy; at least 3 oil separating tanks are arranged, so that the oil-water separation effect can be further improved, and the oil content in the finally discharged water body reaches the discharge standard.
Furthermore, a water outlet is arranged at the bottom of the oil separation tank, and a switch valve is arranged on the water outlet.
The beneficial effects produced by adopting the scheme are as follows: when the oil separating tank needs to be overhauled and maintained, oily wastewater in the oil separating tank can be drained through the water outlet, and overhauling is convenient.
Further, the height difference between the adjacent water outlet pipes is 100-200 mm.
The beneficial effects produced by adopting the scheme are as follows: the height difference of 100 plus 200mm is arranged, so that the oily wastewater is favorably discharged into the next oil separating tank, the water storage space of the lower oil separating tank can be fully ensured, and the use effect is improved.
Further, the horizontal height of the water inlet pipe and the water outlet pipe is higher than 2/3 times of the height of the oil separation tank.
The beneficial effects produced by adopting the scheme are as follows: the inlet tube and outlet pipe all set up in the upper portion of dividing the oil tank, are higher than 2/3 times and divide the height of oil tank, and the water storage space in the multiplicable oil tank that divides guarantees that oily waste water has sufficient dwell time in dividing the oil tank to carry out water oil separating, and convenient follow-up separately discharges, improves water oil separating's effect.
To sum up, the utility model has the advantages of it is following:
contain 3 at least branch oil tanks in the device, only be provided with 1 oil removal pipe in every branch oil tank, divide the oil tank to have great storage space, and independent branch oil tank adds the setting that separates oil pipe in addition, has guaranteed oily waste water at the inside dwell time of branch oil tank, has reduced the influence of oily waste water flow to the separation effect for divide oil back aquatic oil content obviously to reduce, the water after the separation accords with emission standard.
