(54) ELECTRIC CLEANER FOR DIELECTRIC FLUIDS

(57) The invention relates to the purification of liquids and makes it possible to increase the efficiency of purification by organizing the flow of fluid in closed cells-accumulators (YAN) of contaminants in the form of cylindrical jets and extracting mechanical impurities from them in all directions within 360 °. The design of the YAN is such that the bridges of dielectric pads have walls equally spaced relative to the longitudinal axes of the slots of the collecting electrodes, and the cuts are made in the form of round holes, thus ensuring the equidistance of the body of the fluid jet relative to the bridges of the dielectric pads. As a result, equal electric forces in all directions act on the jet of fluid flowing through the circular opening in the precipitation electrode. The closure of the YAN eliminates the practical possibility of leaching trapped contaminants into the purified liquid. The dimensions of the YAN provide the necessary mass transfer, while no stagnant zones are formed. 3 il.

The invention relates to devices for the purification of dielectric liquids from mechanical impurities.

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

FIG. 1 shows an electric cleaner, general view; in fig. 2 and 3 - the same, “cross-section, variants.

The electric cleaner consists of a housing 1, restrictive plates 2, a package of collecting electrodes 3, dielectric gaskets 4 with bridges, branch pipes inlet 5 and drain 6 of liquid. The precipitation electrodes 3 are made in the form of circular metal plates with holes 7, between the collecting electrodes there are sets of closed identical storage cells 8, which are formed by bridges of dielectric spacers 4, and the holes 7 in the collecting electrodes are located along the axis of symmetry of the storage cells 8, Transverse a section of a closed cell in a dielectric strip 4 may be in the form of a dense package of drive cells. In a cleaner, storage cells can be cylindrical (FIG. 2) and honeycomb (FIG. 3). The package of electrodes is assembled in such a way that the holes 7 in the electrodes form flow channels for the passage of fluid, and the spaces between two adjacent electrodes 3 and the closed cells of the dielectric spacers 4 form individual pollution cells 8.

The clutches 4 are bounded on two sides by plates 2. These restrictive plates 2, made of a dielectric material, center the package of collecting electrodes in housing 1. The slits 9 in the limiting plates serve pro-liquid. Precipitation electrodes 3 are connected to a high voltage source. The alternation of the sign of the potential on the precipitation electrodes is achieved during the search.

The electric cleaner works as follows.

When the package of electrodes 3 is connected to a high voltage source between adjacent electrodes, a potential difference arises. The presence of an electric field symmetric with respect to the flow axis in the individual yoke accumulator 8 ensures the removal of soil particles in all directions (by 360 °) due to the formation (electric wind. The dirt particles are removed from the flow in the storage cells 8 and deposited on the electrodes 3. The presence of an electrically insulating layer on the electrons 3 eliminates the recharging of the settled particles. Because contaminants accumulate in the confined space of the drive cells 8 and are not affected by the main flow liquid, then the possibility of leaching them is practically eliminated. The performance of an electrocleaner that provides a given thinness of the liquid cleaning depends on the number and size of the collecting electrodes, the number of holes and the voltage applied to supply the electrodes, accumulators, contaminants and viscosities of liquids. The cleaner provides for the removal of particles of contaminants whose dielectric constant is higher than the dielectric constant of the liquid.

The application of the invention improves the efficiency of cleaning fluid.
