The device comprises an oil-water emulsion preparation device, a V-type dynamic electric coalescence device, an image acquisition and treatment device and a circulation recovery device; the oil-water emulsion preparation device comprises a sedimentation tank, a water storage tank and a stirring reactor,wherein the sedimentation tank and the water storage tank are connected with an inlet of the stirring reactor separately, an oil-well pump is arranged between the sedimentation tank and the stirring reactor, and the bottom of the sedimentation tank is provided with a water outlet; an outlet of the stirring reactor is connected with an inlet of the top of the V-type dynamic electric coalescence device through a diaphragm pump; the inner portion of the V-type dynamic electric coalescence device is provided with one or more groups of V-shaped electrode plate sets, each V-shaped electrode plate set comprises an upper layer electrode plate and a lower layer electrode plate, the upper layer electrode plates and the lower layer electrode plates are arranged in parallel in a V shape, the upper layer electrode plates are connected with the positive electrode of a high-voltage electrostatic generator, the lower layer electrode plates are connected with the negative electrode of the high-voltageelectrostatic generator; the bottom of the V-type dynamic electric coalescence device is connected with a recycling device, and the design is more compact in structure and higher in efficiency than existing design.

Description

technical field [0001] The invention belongs to the technical field of dehydration dynamic experiment equipment, and in particular relates to a V-type electric coalescence dehydration dynamic experiment device. Background technique [0002] Domestic oil production has entered the middle and late stages, and the use of tertiary oil recovery methods such as chemical flooding and compound flooding has made crude oil heavier and inferior, and the difficulty of pretreatment has greatly increased. Increased transportation energy consumption, catalyst deactivation and other issues have brought great pressure to the stable production of the device and the discharge of sewage from the refinery. Under the environment of "green economy, low-carbon economy, energy saving and emission reduction" strongly advocated by the country, how to improve the desalination and dehydration effect of heavy and inferior crude oil and reduce the energy consumption of equipment as much as possible has be...
