AI Technical Summary
Existing oil-water separation equipment cannot completely separate the water and oil phases, resulting in some oil phase being mixed in with the water phase, causing water pollution.
Design an oil-water separation structure, including a separation tank and a heating resistor. The heating resistor generates heat to cause the oil phase in the aqueous phase to separate into layers and suspend above the aqueous phase. The oil overflows into the oil tank through the overflow port. Combined with a communicating vessel structure, the oil phase is further separated by the density difference between oil and water.
It improves the oil-water separation effect, ensures that the residual oil phase is separated during the drainage process, avoids oil phase solidification, and improves the overall separation efficiency of the oil-water separation equipment.
