SU1233902A1 - Electrocoalescent apparatus for processing emulsion of water in oil type - Google Patents

Description

The invention relates to devices for the treatment of water-in-oil emulsions in an electric field and can be used in the refining, petrochemical, petroleum and 1 azov industries.

The aim of the invention is to improve the efficiency of the process of coalescence of water droplets by creating an initial part of the treatment of the emulsion of the zone of increased tension of the electric field.

Fuck | -. 1 shows electrocoalescing), longitudinal section; in fig. 2 is a section A-A in FIG. one; in fig. 3 - section BB in FIG. one; in fig. 4 shows an embodiment of the nozzle of FIG. one.

Electrocoalestration unit 1, the apparatus contains a cylindrical body 1 with an inlet 2 and an output 3 unions, mounted on the insulator 4 through the coupling sleeve 5, the electrode 6, the branch pipe 7 and the horizontal non-housing 8 located between the body 1 and the branch pipe 7 below the entry point of fitting 2. Electrode 6 in the embodiment shown in FIG. 3, is equipped with longitudinal ribs 9. A socket in the embodiment represented by pa of FIG. 4, is made expanding with a huddig woa e p and e 1 st lanes and.

The device works in the following way: Emu.1c11i type water in oil through nozzle 2 enters the area between housing 1 and nozzle 7, where the emulsion flow is distributed over the annular gap, then the flow turns 180 ° and enters the high field electric field. between pipe 7 and elek0

In this region, from this zone, the flow of liquid enters the electric field of the lower field between the electrode 6, the housing 1, and then the treated emulsion flow is led out of the apparatus through the ptucer 3.

The proposed design solution also allows creating a fluid flow with a more uniform velocity field over the cross-section of the nozzle, which also means the efficiency of the AP operation.

At the same time, support-i.e., an electric field of the required strength is achieved at low power consumption. the completion of an electrode with a nrodo,: 1 ribs with ribs contributes to a higher electrical heterogeneity), which also intensifies the coalescing process and reduces the total energy consumption, and the elongation of the branch pipe in the direction of the partition optimizes the nature of the electric field along the scale of It is located on the patch of the plot and creates more favorable hydrodynamic conditions for distributing the flow of the flow over the nof |
