The device for separating the oil and the wastewater shown in the accompanying drawings 1 to 3 comprises a shell 2, wherein a storage chamber 18 is arranged in the shell 2, a separation chamber 4 is arranged in the storage chamber 18, the separation chamber 4 is in a barrel shape, the storage chamber 18 is in a barrel shape, and the center line of the storage chamber 18 and the center line of the separation chamber 4 are not in the same straight line.
One end of the water inlet pipeline 8 is communicated with the grit chamber 1, the other end of the water inlet pipeline 8 is communicated with the separation chamber 4, and the position of the pipe wall of the water inlet pipeline 8 is coincident with the tangent line of the separation chamber 4, so that sewage enters the separation chamber 4 along the tangent line direction of the separation chamber 4, a sewage isolation grid is arranged at the communicated position of the water inlet pipeline 8 and the grit chamber 1, particles and floating garbage in the sewage are removed, and the liquid inlet 14 is prevented from being blocked after the floating garbage enters the separation chamber 4. The separation chamber 4 is internally provided with a conveying pipeline 10, a liquid inlet 14 of the conveying pipeline 10 faces upwards, the liquid inlet 14 is positioned in the center of the separation chamber 4, a liquid outlet of the conveying pipeline 10 is communicated with the storage chamber 18 and the separation chamber 4, and the conveying pipeline 10 is used for conveying separated oil stains to the storage chamber 18. An outlet chamber 26 is arranged in the storage chamber 18, the bottom of the outlet chamber 26 is communicated with the storage chamber 18, a water outlet pipeline 28 is connected to the shell 2, and the water outlet pipeline 28 is communicated with the outlet chamber 26.
An overflow channel 21 is arranged in the separation chamber 4, the inlet of the lower end of the overflow channel 21 is communicated with the separation chamber 4, the outlet of the upper end of the overflow channel 21 is communicated with the outlet chamber 26, and the outlet of the upper end of the overflow channel 21 is positioned higher than the position where the water outlet pipeline 28 is communicated with the outlet chamber 26.
A communication port 34 is provided on the wall of the separation chamber 4 near the upper end thereof, the separation chamber 4 and the storage chamber 18 are communicated through the communication port 34, and the bottom of the communication port 34 is located higher than the upper end outlet of the overflow path 21. An inlet 38 is arranged at the top of the shell 2, which is convenient for maintenance, inspection and oil stain removal. The oil in the reservoir chamber 18 is periodically cleaned through the upper inlet port 38 and the clean water in the lower portion of the oil is discharged through the outlet conduit 28.
As shown in fig. 2, under normal flow conditions, i.e. when the water level flowing from the surrounding area into the separation device is relatively low, the flow velocity of the mixture in the separation chamber 4 is small, the liquid level in the separation chamber 4 can be regarded as horizontal and a swirl flow is formed around the transfer pipe 10. The oil dirt at the liquid level in the separation chamber 4 enters the storage chamber 18 through the transfer conduit 10 so that the oil dirt is concentrated at the liquid level in the storage chamber 18, and the lower clear water enters the outlet chamber 26 and is discharged through the outlet conduit 28. The surface waste water containing high concentration of oil dirt in the reservoir chamber 18 is periodically extracted through the upper inlet and outlet 38 and then secondarily precipitated.
As shown in fig. 3, under high flow conditions, the flow rate into the separation chamber 4 is large, the flow rate of the mixture in the separation chamber 4 is large, and the liquid level in the separation chamber 4 can be regarded as parabolic. When the liquid level is lower than the bottom of the communication port 34 and higher than the upper end outlet of the overflow channel 21, the oil dirt at the liquid level in the separation chamber 4 still enters the storage chamber 18 through the conveying pipeline 10, while the clear water separated by the oil dirt mainly enters the outlet chamber 26 through two channels, and the first channel enters the outlet chamber 26 through the communication position between the bottom of the storage chamber 1 and the outlet chamber 26 and is discharged through the water outlet pipeline 28; the second channel overflows through overflow channel 21 into outlet chamber 26 and likewise discharges through outlet conduit 28.
Because the liquid inlet 14 is at the lowest point of the parabolic liquid level, the static pressure head above the liquid inlet 14 is not significantly higher than that under the condition shown in fig. 2, so that the flow state of the conveying pipeline 10 is not significantly changed, and the turbulence phenomenon under the action of large flow can be relieved.
As shown in fig. 3, also under the condition of high flow rate, when the liquid level is higher than the bottom elevation of the communication port 34, one part of the greasy dirt at the liquid level in the separation chamber 4 enters the storage chamber 18 through the conveying pipeline 10, and the other part overflows into the storage chamber 18 through the communication port 34; the clean water separated by the oil dirt still enters the outlet chamber 26 through two channels and finally is discharged through the outlet water pipe 28.
The foregoing describes preferred embodiments of the present utility model. It should be understood that numerous modifications and variations can be made in accordance with the concepts of the utility model by one of ordinary skill in the art without undue burden. Therefore, all technical solutions which can be obtained by logic analysis, reasoning or limited experiments based on the prior art by the person skilled in the art according to the inventive concept shall be within the scope of protection defined by the claims.
