Novel integrated oil-water separation device

Abstract

The invention discloses a novel integrated oil-water separation device, comprising an inner circular barrel and an outer circular barrel which are concentric, wherein the inner circular barrel forms a centrifugal separation area (2) and an adsorptive separation area (8) from top to bottom, and the inner circular barrel and the outer circular barrel form an annular-space gravity-settling separation area (5); the gravity-settling separation area (5) is provided with a clapboard, an oil-water mixture inlet (4) is formed on the upper part of one side of the clapboard, and a water through port for entrance in the centrifugal separation area (2) is formed at the other side; and the centrifugal separation area (2) is provided with an oil discharge port (12), and a water drainage port (15) is formed on the bottom of the adsorptive separation area (8). The novel integrated oil-water separation device disclosed by the invention has the advantages of being high in oil-water separation efficiency, simplicity in machining, as well as simplicity and convenience in operation by coupling a gravity principle with a centrifugal and adsorptive separation principle.

Description

technical field [0001] The invention relates to a device for treating oily waste water, in particular to an integrated oil-water separation device. Background technique [0002] According to the state of oil substances in water, they can be divided into floatable oil, dispersed oil, emulsified oil and dissolved oil. The current oil-water separation methods mainly include gravity separation, centrifugal separation and air flotation separation. Both gravity and centrifugal separation use the difference in density between oil and water to separate oil and water under the action of gravity and centrifugal force. The most commonly used equipment for gravity separation is the grease trap. The oily wastewater flows in from one end of the pool and flows through the pool body at a relatively small flow rate. During the flow, the oil particles with a density less than water rise to the water surface, and the water flows from the pool The other end flows out, and the oil-water separa...
