The invention relates to a technique for cleaning viscous dielectric fluids and can be used in the preparation of oil in fields and in the regeneration of waste oils in oil depots.

The purpose of the invention is to increase the efficiency of cleaning fluid.

The drawing shows schematically the device section.

The device consists of a cylindrical body 1 with tangential nozzles of the inlet 2 and outlet 3 of the buffer fluid and axial nozzles for connecting 4 and output 5 of the liquid to be cleaned. Inside the housing 1, there are mesh electrodes 6 mounted on the dielectric rod 7 and mounted on dielectric supports 8. When cleaning highly inert liquids, the electrodes 6 are connected alternately to different poles of the current source. For deep cleaning of low-fluids, electrodes 6 can be connected to one pole of the current source, and the other pole is connected to housing 1. The size of the electrode cells is reduced along the stream.

The device works as follows.

The buffer fluid is fed tangentially into the body through the nozzle 2 and is withdrawn through the nozzle 3. Due to centrifugal forces, the buffer liquid forms on the walls of the body 1 a film whose thickness is regulated by the amount of liquid supplied. Next, through the pipe 4 into the housing 1 serves the purified liquid. When the fluid passes through the grid electrode 6, the particles of impurities contained in it and the contact electrode 6 move from the electrode 6 of the same charge with them to the housing 1 and, falling into the flow of buffer liquid, are withdrawn from it from the housing 1. Purified impurity buffer the fluid is fed back to the nozzle 2, and the purified dielectric fluid is discharged through the nozzle 5.

If a highly concentrated liquid is subjected to cleaning, then it is advisable to connect the electrodes 6 to different poles of the current source, since in this case the particles of impurities will intensively coagulate and become larger under the action of external

the floor between oppositely charged adjacent electrodes 6.

If a low-level liquid is cleaned, it is more rational to connect

all electrodes 6 to one pole of the current source, and the housing 1 to the other. In this case, the particles coagulate very slowly and the external field between the electrodes 6 is not necessary; for

operation of the device is sufficient external field between each electrode 6 and the housing 1, and the absence of an electric field between the grid electrodes 6 will reduce power consumption.

By performing the mesh electrode and placing the supply and removal nozzles of the buffer fluid, and the input and output nozzles

the fluid being cleaned along the axis of the housing; the buffer fluid, rotating, twists also the axial flow of the fluid being cleaned, as a result of which the particles of contaminants are removed from the latter

in the flow of buffer fluid around the perimeter of the body, not only due to electric, but also centrifugal forces. By increasing the surface of the electrode and the centrifugal forces acting on the particles of contaminants, an increase in the efficiency of cleaning the liquid in the proposed device is achieved.

The quality of fluid cleaning is improved if additional mesh electrodes are placed inside the case. It is advisable to reduce the size of the cells of the grid electrodes along the flow of the liquid being cleaned, this 40 will reduce: clogging of the grids at the beginning; cleaning and ensure high quality at the end of the liquid cleaning zone.
