The invention relates to the industrial and agricultural production and
environmental protection fields. Oil droplets and water in a mixed original liquid are forced to move in opposite directions, and the purposes are achieved ingeniously that the force is unchanged and the mechanical motion effects are amplified for n times, just like the oil droplets and water are separated by a force amplified for n times, the separated
free water can be forced to be discharged automatically at the water deep where oil droplets cannot reach, and oil and water separation is achieved without a demulsification technology. In addition,
free water can be forced to stay in an adjusting water tank with a very low
water level for
discharge and the oil liquid is discharged at a high oil level far higher than the
water level of the adjusting water tank automatically. A heater is arranged in the only path of the oil liquid to guarantee the mobility of the oil liquid. The heater only heats oil and does not heat water, high efficiency and low consumption are achieved, and high-precision oil and water separation of highly thickened oil,
crude oil with a density of more than 1 and aged
oil can be achieved in a low temperature in a high-efficiency and low-consumption manner. The oil and water separator can be used in a reversed manner, and can become a high-efficiency and low-consumption de-oiling
machine, and high-purity oil-free pure water can be obtained. The advanced degree of the method is far better than that of the present oil and water
separation technology and great market return can be obtained.
