Description

(54) ELECTRIC CLEANER

The invention relates to electrical technology, in particular, to devices intended for the removal of particles of mechanical impurities from a stream of liquid or gas.

An electrostatic filter for cleaning liquids is known, including a grid installed across the liquid stream and electrically charged by electrification 1.

A disadvantage of the known device is the low efficiency of the particle separation process.

The closest in technical essence and the achieved effect is an electrocleaner, which includes a housing, electrodes of opposite polarity, covered with a lint filtering layer, inlet and outlet nozzles, and a filter box 2.

The disadvantage of the device is low feasibility.

The purpose of the invention is to increase the productivity when cleaning dielectric liquids.

The goal is achieved by the fact that the electrodes are made in the form of a grid with a filtering brist, directed towards the flow, and wires, and the grid and the wire are interconnected electrically. and electrodes of different polarity are installed with alternation in the direction of flow.

FIG. 1 shows the electric cleaner circuit; in fig. 2 - part of the precipitated mesh electrode.

The electric cleaner consists of a housing 1 with an inlet 2 and outlet 3 nozzles.

Inside the case, ionizing race wires 4, 5, 6 and grids 7.8 are provided, one side of which, facing the flow, is covered with a filter layer in the form of a pile 9, with wire 5 connected electrically to grid 7 and the negative pole isothermal nifrf and, wire 6, connected to the grid 8 and the postgun pole of the power supply, and. D. Obra.uyug elekgr. . different polarity with alternation along the moving stream. To collect the sediment 10 is a grinder screen with a screen 12 and a grid view.

Electrostatin works as follows.

Contaminated dielectric fluid through the inlet pipe 2 enters the electric cleaner. Under the action of a voltage applied to the electrodes of the voltage (1 O-20 kV), the pile is oriented along the power lines of the electric field, which practically coincides with the direction of flow of the liquid being cleaned. The particles of the contaminants are charged near the ionizing electrode 4 and, falling into the narrow shells between the villi of the mesh 7, are deposited on their curvature, forming sediment 10. The liquid from which the bulk of the particles of contamination is thus removed enters the zone of action by the following pair electrodes: ionizing wires 5 and sieves 8.

During the breakdown, the voltages are removed from the electrodes and the fluid is not pumped through the cleaner. The particles are discharged, detached from the villi and fall into the collection container 11 through the screen of several layers of the grid 12.

Providing high quality cleaning of the dielectric fluid, the electric cleaner has 3-6 times greater productivity, since the average flow rate of the liquid through the cleaner is chosen equal to the speed of the liquid from the ionizing electrode to the precipitation one.

Thus, the use of technical solutions will improve the performance of electric cleaners.
