Problems solved by technology

[0006] In fact, this assumption is not valid. Under the condition of power ultrasound, the ultrasonic wave decays rapidly in the emulsion, and the ultrasonic wave with the power required to break the emulsion can only exist at a short distance from the front of the probe’s emitting surface. Therefore, , the ultrasonic demulsification area that can be provided by the several ultrasonic demulsification schemes disclosed above is actually very small, and the expected demulsification effect cannot be achieved.
[0007] At the same time, due to technical needs, the action

Abstract

The invention relates to an emulsion ultrasonic emulsion breaking device, which comprises a cavity provided with an input port and an output port, wherein the input port and the output port are arranged on the cavity in an upper-lower matched pair or a lower-upper matched pair, namely the input port is arranged close to the lower end of the cavity, the corresponding output port is arranged close to the upper end of the cavity, and vice versa; and the wall of the cavity is provided with at least one ultrasonic wave generating device through flanges, and a tool head of the ultrasonic wave generating device has a candied gourd shape and is arranged in the cavity. Under the action of the gravity, the emulsion ultrasonic emulsion breaking device achieves balanced flow of an emulsion in an acting cavity, adopts an ultrasonic vibration system, makes full use of ultrasonic waves sent to the circumference from a lateral surface of a rod by the ultrasonic tool head immerged into the emulsion to enlarge the action zone of the ultrasonic waves in the cavity as large as possible, and improves the efficiency and the effect of ultrasonic emulsion breaking. The emulsion ultrasonic emulsion breaking device is adaptable to oil-water emulsion breaking separation.

Description

technical field [0001] The invention relates to a device for demulsification and separation of oil-water emulsion, in particular to an emulsion ultrasonic demulsification device for accelerating oil-water separation by means of ultrasonic waves. Background technique [0002] In petroleum, petrochemical and other industrial production, an important process is to open the tightly bound "water-in-oil" or "oil-in-water" particles, that is, to break the emulsion, and then use the density difference between oil and water , at a certain temperature, the complete separation of oil and water is achieved through sedimentation, centrifugation, etc. At present, in addition to using ordinary thermochemical demulsification in industrial production, that is, adding a chemical demulsifier to the emulsion to speed up the oil-water separation process, the vibration and cavitation of the ultrasonic wave acting on the liquid are used to realize the oil-water emulsion. Demulsification and dehyd...
