The invention relates to devices for the destruction of a water-oil emulsion in an electric field and can be used in the oil industry and the petroleum industry.

The purpose of the invention is to increase the efficiency of oil dehydration and increase the reliability of the dehydrator.

Figure 1 shows an electrode dehydrator; figure 2 - section aa in figure 1; FIG. 3 shows the spectrum of the resulting electric field in the electrode-hydrator.

Electrodehydrator consists of a tank 1 in which there is a nozzle 2 for injecting an emulsion, a nozzle 3 for outputting very valuable petroleum products, and nozzles 4 for evacuating residual water. In addition, wire electrodes 5 are installed in the tank and are fed from insulators 6 high voltage, between them are ebonite tubes 7 in which rod electrodes 8 are arranged in the form of perlonov rods rotating from a separate motor (HG shown).

Electrodehydrator works as follows.

When a high voltage is applied to the grid electrodes and the rod rotates ЕЕ-гх electrodes, the main field and the field of electrization arise, which, summing up, form the resulting non-uniform electric field with two zones (Fig. 3).

When applying the oil emulsion, first, in the zone A (the zone of reduced polarity), the globules with the elevated content of various kinds of conductive inclusions (with a higher value

electrical conductivity). The presence of a high degree of non-uniform non-stationary floor does not allow globules to co-current in the process of their coalescence.

In the noBbmjeHHbix zone of values of field strength (zone B), the remaining globules possess elevated dielectric constant values. Globules of equal values of electrical conductivity and smaller ones: sizes are polarized in zone B, and larger ones in zone A.

The enlarged globules fall to the bottom of the tank and through pipes 4 enter it into a special sewage system. Such a differentiated polarizability of the globules provides, on the one hand, a higher reliability of the device, and on the other hand, a higher degree of oil purification, especially high viscosity, characterized by higher dielectric constant values.

The technical and economic efficiency of the dehydrator is determined by the fact that the quality of refined oil increases, the cost of

its processing - the consumption of heat and energy, increases the reliability of work. Invention Formula An electrodehydrator, including a tank in which rod electrodes are installed that are rotatably mounted in tubes, which is due to the fact that, in order to increase the efficiency of oil conveying and increase reliability of operation, the Electrodehydrator is equipped with grid electrodes connected to a high voltage source. Moreover, the rod electrodes are installed between the grid ones.  yiizhenie petroleum Fig.z Compiled by O. Kal Kina Editor V. Petrash Tehred M. Khodanich Proofreader M.
