An oil discharge area 11 is provided on the upper side wall of the oil separation area 3 and recovers the oil through a pipe. The bottom of the clear water zone 4 is provided with a water discharge pipe 12 for finally realizing the separation of water and oil.
The separation process is as follows:
the diaphragm pump is used for pumping the oil-water mixed liquid from the liquid storage tank to the oil-water mixed area, then the oil-water mixed liquid slowly rises in the oil-water mixed area, and due to the principle that water is heavier than oil, the oil floats on the surface of the water, the water is at the bottom of the oil-water mixed area, and the oil floats on the upper portion of the oil-water mixed area. The water arranged at the lower part of the oil-water mixing zone can flow to the first oil-water separation pipe, when the liquid level of the oil-water mixing zone is higher than that of the first oil-water separation pipe, the water can overflow from the upper pipe orifice of the first oil-water separation pipe, and the overflowed liquid is clear water. When the liquid level of the oil-water mixing area is higher than the baffle, the oil passes through the baffle and enters the oil filtering area because the upper layer of the liquid level is the oil, and the oil entering the oil filtering area directly flows into the oil separating area because the oil filtering area is communicated with the oil separating area. The oil and water separation is realized preliminarily. In the scheme, the key point is that the upper end opening of the first oil-water separation pipe is arranged in the clean water area and is lower than the upper end outlet of the clean water area, so that the realization is relatively smooth, the height difference between the two positions cannot be too large, the height difference is generally related to 10-50mm, and the adjustment is carried out according to the flow of the diaphragm pump.
