Description
Technical field
The present invention relates to a kind of device that oil-water emulsion is carried out the breakdown of emulsion separation, is a kind of emulsion ultrasonic emulsion breaking device of accelerating water-oil separating with the ultrasonic wave mode specifically.
Background technology
In industrial production such as oil, petrochemical industry, there be one important operation to be in intimate-association state " Water-In-Oil " or " oil-in-water " particle is opened, it is breakdown of emulsion, then, utilize the density contrast between oil, the water, at a certain temperature, realize the separation fully of profit by sedimentation, mode such as centrifugal.At present, in the industrial production except using common thermo-chemical demulsification, promptly by in emulsion, adding chemical demulsifier, accelerate outside the technology of water-oil separating, effects such as the vibration when utilizing ultrasonic wave to act on liquid, cavitation, realize the breaking emulsion and dewatering of oil-water emulsion, be considered to a kind of effective method.
Patent CN2296230 discloses a kind of " ultrasonic demulsifier of crude oil electric field dehydration ", it is made up of supersonic generator, ultrasonic wave active region, transmission cable and ultrasonic probe, and the ultrasonic wave active region is the cavity that is connected on a preceding horizontal positioned of electric dehydration jar.Ultrasonic probe is installed on the outer wall of this cavity by supported flange and the flange that is welded on the chamber outer wall of ultrasonic wave active region, and links to each other with supersonic generator by transmission cable, and a plurality of ultrasonic probes are perpendicular to the direction acting in conjunction of liquid flow.
