Abstract

FIELD: process engineering.

SUBSTANCE: invention relates to cleaning of dielectric fluids. Proposed device comprises casing 1 and precipitation electrodes 2, 3 made up of metal plates with passages for medium to be cleaned and baffles 4 and two perforated plates 10 made from dielectric material arranged between electrodes and on both sides of said pack of electrodes, respectively. Said electrodes are connected to high-voltage source with alternating sign of potential. Bushing 7 is arranged all around said pack and made from antivibration material, for example, rubber, and fitted between casing inner side surface and pack of electrodes with dielectric baffles. Ring 9 from material identical to that of said bushing is arranged between cover and plate on the faces of said pack of electrodes and inside said casing. Electrical cleaner casing takes up vibrations from mechanical means it is mounted on. Pack of electrodes does not take up said vibrations directly. These are transferred to antivibration bushes and rings that dampen them on being deformed. This allows resting state for electrodes to prevent premature separation of impurities accumulated on electrodes surfaces and ingress into cleaned medium.

EFFECT: longer life.

Description

The invention relates to a device for cleaning dielectric media.

Known electric purifier of dielectric liquids and gases with a water absorber [1], which includes a housing with two covers at the ends and fittings of their input and output, precipitation electrodes made in the form of metal plates in the shape of the housing in plan, between which are placed columns of dielectric material, and between the collecting electrodes is a layer of solid adsorbent from the liquid being purified water or gas such as zeolite or silica gel, wherein the collecting electrodes are connected to a source of high a voltage with alternating sign of the potential.

The disadvantage of this cleaner is the lack of vibration protection in it.

Also known is an electric cleaner of dielectric liquids (and gases) with a one-sided arrangement of holes in the electrodes [2], including a housing and precipitation electrodes with holes connected to a high voltage source with alternating sign of potential, between which are placed partitions of dielectric material, and the electrodes have one the hole is close to the edge, and when assembling the holes in the adjacent electrodes are diametrically opposed.

The disadvantage of this cleaner is also the lack of vibration protection in it.

Known electric cleaner of dielectric liquids (and gases) with rounded holes in the electrodes [3], including a housing and precipitation electrodes, made in the form of metal plates with holes that form channels for the passage of liquid or gas, and equipped with baffles of dielectric material, and the electrodes are connected to high voltage source with alternating sign of the potential, and the holes are made with rounded edges.

The disadvantage of this electric cleaner, adopted as a prototype, is the lack of vibration protection in it.

The aim of the invention is to eliminate the disadvantage of the prototype, based on the placement in the electric cleaner of vibration protection of the electrodes, which ensures a longer operation of the electric cleaner between cleaning the electrodes from the accumulated dirt and prevents separation of contaminants from the electrodes, under the influence of vibrations, and getting them into a clean stream.

The technical result of the invention is achieved in that the block of electrodes with dielectric partitions has vibration isolation from the housing with covers, made in the form of a layer of material - an absorber of vibrational energy, such as rubber, deforming under the influence of vibrations and damping these vibrations, without transferring them to the electrode block from the housing with electric cleaner covers.

When installing electric cleaners on mechanical devices, for example on a car, from the last vibration (and other) vibrations will be transmitted to them. First of all, these fluctuations will be perceived by the body of the electric cleaner with covers. And already from the housing or from the covers, these oscillations will go to the electrodes on which the deposition of contaminants is carried out. These contaminants accumulate, the thickness of their layer on the electrodes increases. Since no electric field is distributed uniformly in the space between the electrodes, and the thickness of the layer deposited dirt will unevenly appear projections and depressions. When the thickness of the deposited layer substantial contaminants under the action of vibration (or other) fluctuations with protrusions will rip lumps of dirt and the cleaned stream of entrained liquid. Since the mass of these detached pieces of contaminants will be large enough, they will not settle on the surface of subsequent electrodes being cleaned by the flow of the liquid being cleaned (or gas), but will remain in the liquid being cleaned (gas), i.e. the liquid (gas) will be contaminated not with small mechanical particles, as before entering the electric cleaner, but with large lumps of these particles connected to each other, which is not the best, but the worst option. The thickness of the layer of contaminants deposited on the surface of the electrodes, at which the separation of lumps of settled mechanical particles begins under the action of vibrational, and any vibrations, depends on the strength of these vibrations: the stronger the vibrations, the thinner the layer thickness and vice versa. Therefore, it is necessary to protect the electrodes of the electric cleaner from the effects of these vibrations.

The essence of the invention lies in the fact that between the inner side surface of the body of the electric cleaner and the block of electrodes with dielectric partitions a cylindrical sleeve is installed, along the entire length of the block of electrodes, from absorbing vibration (and any other vibrations and inertial loads) of the material, for example rubber, and between each cover and a plate at the ends of the electrode block, inside the housing, there is a ring of the same material as the sleeve.

A comparative analysis allows us to conclude that the proposed device differs from the prototype in the presence of vibration-damping bushings and two rings in it, and this makes it consistent with the criterion of "novelty."

Analysis of the known technical solutions (analogues) in the studied area allows us to conclude that there are no signs in them that are similar to the essential distinguishing features in the claimed device, and to recognize it as meeting the criterion of "significant differences".

The use of all the new features can significantly increase the duration of the electric cleaner between cleaning the electrodes from the impurities deposited on them, and this reduces the downtime of the equipment for cleaning dielectric liquids and gases.

Figure 1 shows a longitudinal section of an electric cleaner of dielectric liquids and gases with vibration isolation. It consists of a housing 1 with covers 12 at the ends into which the inlet 5 and outlet 6 fittings are screwed. The cover on the outlet side, the bleed valve is located within the housing 8 are arranged electrodes 2 and 3 connected to different poles of the high voltage DC source. Between adjacent electrodes are installed partitions 4 of dielectric material with holes. At the ends of the electrode block placed plate 10 with holes of dielectric material. Between each of these plates and the lids 12 are two vibration-proof ring 9, and between the housing 1 and the electrode sleeve unit 7 is also of a vibration material. When assembling the electric cleaner, the sleeve 7, inside of which the electrode block is tightly mounted, is also tightly inserted into the housing 1. The plates 10 are located in the grooves of the rings 9, which are placed inside the housing 1 until the plates 10 come into contact with the electrode block. The rings are made of such size as to protrude beyond the ends of the housing 1. When the lid 12 are connected to the housing 1, the rings 9 are compressed and the compressed whole electrode unit. Thus, between the block of electrodes on which contaminants are deposited from the medium to be cleaned, and the body of the electric cleaner, in its transverse direction, there is a layer of vibration-absorbing material of the sleeve 7, and in the longitudinal direction, the block of electrodes is separated from the covers of the electric cleaner, rigidly connected with the body, by a layer of vibration-absorbing material rings 9.

The proposed electric cleaner of dielectric liquids and gases with vibration isolation works as follows. The body of the electric cleaner 1 is rigidly connected with the design of a technical device, for example, a car, on which it purifies the dielectric medium from mechanical impurities: liquid in the form of fuel or air in the cabin (cabin). All vibrations from the technical means are transmitted to the housing 1 of the electric cleaner.

However, these vibrations are not directly transmitted to the electrode block, but are transmitted to the sleeve 7 and ring 9. Since the latter are made of vibration-absorbing material, such as rubber, these vibrations will be damped by them and not transmitted to the electrode block. Oscillations in the transverse direction of the electric cleaner will be absorbed mainly by the sleeve 7 and, partially, by the rings 9, in the longitudinal direction by the rings 9. The cleaned medium enters through the nozzle 5 of the cover 12, into the body of the electric cleaner, flows through the holes of the inlet plate 10, block electrodes, the output plate 10, the output connection 6. since the electrodes 2 and 3 are supplied with high voltage alternating sign, then they bude occur precipitation of solids.

The proposed electric cleaner of dielectric liquids and gases with vibration isolation allows the electrode block, inside it, not to perceive vibrations from its body, which ensures a longer operation of the electric cleaner until it is regenerated (recovery).
