Inclined plate oil water separator
Oil water separation is a kind of machine, which is usually used to treat sewage. Because of the requirements of environmental protection, the sewage discharged to the rivers, lakes and sea areas must be treated, and the oil-water separator is needed.

Working principle and main components of oil water separator

This integrated device is mainly composed of inclined plate separator, Gexin water oil separator (including prefilter, gravity separator, Gexin coalescence separator and adsorption filter) and corresponding supporting devices. The process principle is as follows:

(1) the sewage is pumped into the inclined plate separator. The sewage pump has strong self-priming capacity, uniform flow, and no mechanical shear emulsification for oil, so it is suitable for the transportation of oily sewage.

(2) the inclined plate separator can effectively remove the floating oil and free oil in the water. The floating oil rises to the surface of the separator and flows into the sewage tank, while the settled sludge is discharged regularly.

(3) the sewage treated by the inclined plate separator flows into the buffer water tank by itself, and the water tank is equipped with a liquid level switch with high and low alarm functions. When the water level reaches a certain height, the sewage lifting pump will be started automatically. When the water level drops to a certain position, the lifting pump will be stopped automatically. The lifting pump sends the sewage to the pre filter and other follow-up equipment for treatment.

(4) the prefilter can effectively filter the fine suspended particles (10 μ m) in the water, protect the new coalescence separator and extend its service life. The prefilter stage is used to remove the impurity particles in the water, prevent the particle as the core and cannot demulsify and remove oil. At the same time, the oil in water is demulsified and then transported to the gravity separator.

(5) the gravity separator makes full use of the characteristics of long process flow to make the fine oil particles fully contact and gradually grow up and float up. More than 80% of the oil is gathered and discharged in this stage, and only a small amount of fine oil particles are transported to the Gexin i-gexin coalescence separator. Therefore, the service life of the coalescence filter element can be greatly extended by the gravity separator.

(6) Gexin coalescing separator is used to remove residual oil (emulsified oil) in water. Coalescing filter element coalesces micro oil drops in water into large oil drops, and makes them float up quickly, and collect them in the oil collecting chamber of coalescing separator. After treatment, the oil content in water reaches less than 5mg / L, which can be directly discharged; the dirty oil collected in the oil collecting chamber is regularly discharged into the oil tank for recycling.

(7) the adsorption filter is equipped with a large capacity activated carbon filter element, which is used for deep adsorption to remove residual organic matter in water and make it meet the emission standard

The inclined plate separator adopts two-stage process to remove the oil and suspended solid particles in the water. The sewage is pumped into the inlet of the oil-water separator. At this time, the flow direction is upward. This initial upward flow can ensure that most of the free oil (floating oil) in the water can quickly rise to the surface of the separator.

The sewage then flows down to the bottom of the separator through closely arranged coalescing plates. During the downward movement of the water, the oil droplets rise, collide and coalesce under the inclined plate, and the countercurrent rises to the surface of the pool. After the sewage flows out from one plate group (countercurrent area), it flows through another plate group, and the oil droplets coalesce again, and rise to the surface of the separator with the help of water flow. After treatment, the flow direction of the sewage changes again on the surface, flows out from under the sewage oil baffle, flows through the overflow weir, and is discharged from the water outlet. The inclined plate separator has the following characteristics:
High separation efficiency, the residence time of incoming water is usually less than 30 min;
The recovered oil does not contain free water;
The change of oil content and suspended solids content in raw water has no negative effect on the effluent;
The equipment is light and small in size;
No moving parts, low operation cost;
