Description
Technical field
The microcosmos experiment device that a kind of electric field is coalesced with dual drop under shearing field coupling, belongs to microcosmos experiment equipment neck
Domain.
Background technology
Oil as a kind of precious non-renewable strategic resources, with the development of society, the consumption of oil with
Demand is growing day by day.China's major part oil field enters the middle and later periods of recovering the oil, and the difficulty that oil is exploited from stratum is greatly increased, and is led to
The method for often taking the tertiary oil recoveries such as chemical flooding, combination flooding, exploits the water content in crude oil come up very high（In the oil field produced oil in part
Water content is up to more than 90%）And exist generally in the form of highly stable water-oil emulsion.Crude oil water containing not only increases accumulating
During energy consumption, and the burn into of equipment can be caused to rush tower, the reduction negative issue such as heat transfer efficiency, therefore, crude oil enter factory it
Before, it is necessary to carry out strict desalting and dewatering processing.
The dehydration of voltolisation knot with it efficiently, the advantages of quick, treating capacity is big, be widely applied.Water droplet is in extra electric field
Effect is lower to polarize, mutual Collision coagulation, water droplet coalescence demulsification, so that gathering into big water droplet obtains sedimentation separation.With offshore oil
Field is continually developed, and offshore platform load-bearing and area limitation, the continuous type voltolisation knot dehydration device to high-efficiency compact propose demand.
In recent years, increasing scholar starts to recognize facilitation of the flowing shearing to drop electrostatic coalescence process, including compact
Type electrostatic coalescer（CEC）, the electrostatic coalescence equipment such as online electrostatic poly- (IEC) and the built-in electrostatic coalescer of container (VIEC)
All more or less will flowing shear action and electric field action.
Under electric field and shearing field coupling, the stress of drop is complicated, and the research to droplet coalescence mechanism is not thorough, especially
It is drop on micro-scale deformation, motion and coalescence experimental study almost do not have.But coupled in electric field and shearing field
Under effect, the coalescence mechanism of drop has the meaning of directiveness to the design and development of the continuous electrostatic coalescer of high-efficiency compact.It is right
The coalescence mechanism research of drop is extremely urgent under electric field and shearing field coupling.
The content of the invention
The technical problems to be solved by the invention are：Overcome the deficiencies in the prior art can be in micro-scale there is provided one kind
