1. working principle of oil-water separator: (catering oil-water separator)

1.

oily sewage is sent to the oil-water separator by a sewage pump, and after passing through the diffusion nozzle, large oil droplets float on the top of the left oil collection chamber.

2.

The sewage containing small oil droplets enters the corrugated plate coalescer at the lower part, where some oil droplets are polymerized into larger oil droplets to the right oil collection chamber.

3.

The sewage containing oil droplets with smaller particles passes through a fine filter to remove impurities in the water, and then enters a fiber polymerizer in turn, so that the fine oil droplets are polymerized into larger oil droplets and separated from water.

4.

after separation, the clean water is discharged through the discharge port, and the dirty oil in the left and right oil collection chambers is automatically discharged through the electromagnetic valve, while the dirty oil separated in the fiber polymerizer is discharged through the manual valve.

second, the working principle of compressed air oil-water separator: (oil-water separator in air compressor system)

When compressed air enters the oil-water separator, the flow direction and speed change sharply, and then oil droplets and water droplets with higher density than compressed air are separated by inertia. The common ones are impact oil-water separator and annular rotary oil-water separator. After the compressed air enters the shell of the oil-water separator from the inlet, the air flow is first blocked by the baffle plate, then bounces back down, and then rises up again, resulting in annular rotation. In this way, water droplets and oil droplets are separated from the air and settled at the bottom of the shell under the action of centrifugal force and inertial force.

3. Working principle of oil-water separator system for vehicles and ships:

1 Water enters through AOD pump (air diaphragm) -->

2 flow control valve enters --> 3. The first-stage honeycomb chamber is flushed with water. Because there are many compact honeycomb compartments in it, tiny particles in the water settle in the honeycomb chamber during the water flow, and wastewater flows in --> 4 mesh water distribution holes (5/32 ") enter -->

5 adsorption chamber and extraction chamber. Water flows into the oil adsorption chamber composed of JT57 liquid filter medium. In this process, oil and grease are absorbed in large quantities and a large number of complex heavy metals, organic substances, TSS, BTEX, PCB and many pollutants in water are extracted. Then the water flow turns upward in the adsorption chamber and enters->; 6. In the second-stage honeycomb chamber, the water flows up and down through the second-stage dense honeycomb interlayer for three times, and the residual trace oil will float up and collect on the upper part, and the water will enter->; 7 clean room, and finally the water is discharged from the bottom of the clean room. For the residual trace oil distributed on the second-stage honeycomb chamber and clean water chamber, it is skimmed into the external oil storage container by the oil skimmer arranged at the top of it and removed.
