Oil and Water Separator Oil Water Separator & Skimmer - Reliable Oil Water Separator

Working principle

The vacuum oil  filtration equipment  researched by  our company has the function of precision filtration and efficient dehydration, removing the particles , emulsion water and free water effectively.
1. Particles Filtration System
Particles filtration system adopts the way of preventing particles to filter. The elements adopt the metal knit mesh and micro glass fiber paper as the material with the features of high precision filtration, large capacity of the pollution and long service time. The device filters in three steps: absorption filter elements (120micro), high efficiency pre filter elements (20micro), high efficiency and precision filtration (3micro).
2. Vaccum Hydroextraction System
Different saturated vapor pressure in different liquid. In 70ºC, the water will boil in the pressure of about 3X104Pa,but oil will boil under 5Pa.In the same  temperature,the  saturated vapor pressure of oil is much lower than water. So, when the oil liquid surface pressure is lowered under the saturated vapor pressure by the way of  vacuum, the moisture existing in oil will be changed extremely, and escape from the oil as steam.
According to the vacuum absorption, oil liquid runs into the vacuum box and spray down. The moisture existing in oil liquid is changed to be steam in the vacuum room and drew out by the vacuum pump, the oil liquid  without moisture escape from the bottom. In the vacuum room, there are materials which is in harmony with oil. When the oil liquid sprays in the vacuum room, the oil form a film in the surface of the  material, enlarge the area of the steam and liquid, prolong the time of delay  time  of oil  liquid  in the space.
The efficiency of vacuum hydro extraction has relation with the working stable vacuum and the temperature of the oil liquid. Lower vacuum class and higher temperature result in better efficiency. Oil temperature is about  60ºC, if the oil temperature is  too  high, it  will  accelerated the oxidation of the oil liquid. For the hydraulic oil, working stable vacuum is about 600~700Pa, which can reduce the moisture to be under 100ppm. For the transformer insulating oil, it  can adopts higher working vacuum class, the moisture existing in water could be under 10ppm. It can remove variety moisture ,air and volatile matter in oil effectively.

Working Process

The dirty oil runs into the system from the entrance ball valves under negative pressure, go through the absorption oil filter to remove the coarse particles to protect the pump, then heated by the heaters step by step to a permanent temperature controlled by the automatic temperature control unit ,comes to the vacuum separator to fall down by the allotter. It forms a oil film by he packing material, and the moisture and air in the oil liquid are boiled out of the vacuum environment, making the separation of oil and water. Most of the steam runs into the steam trap to be water, and the rest escape out of the vacuum pump together with the volatile air. The oil liquid without moisture runs out of the oil drain pump, filtered by two steps high precision for the delicate particles, and drain our from the oil pump to finish a working recycling.
