Description

one

The invention relates to process equipment for cleaning dielectric fluids and can be used in civil aviation.

According to the main author. St. No. 759137 of the well-known device includes a housing equipped with pockets in which chargers are placed, made in the form of discs mounted on a shaft. Part of the surface of the disk is located in the body P.

However, when the disks rotate due to the forces of friction, disks and emulsion fuel arise in the mezzanine, the rotational motion of the particles of contamination and water occurs in the electrocyclone. Due to the large inertia of the mass of fuel, acceleration and stopping of the fuel in an electric cyclone will take a lot of time, as a result of which the efficiency of the electric cyclone decreases.

The purpose of the invention is to increase the efficiency of the electro-cyclone.

The goal is achieved by the fact that the casing is equipped with tangential injection and suction nozzles connected to a pump, mounted inside the casing on vertical shafts with braking vanes, kinematically interconnected, for example, by a lever system

10 with a drive, the inner surface of the braking vanes being made with a radius equal to the distance from the center of the housing to the shaft, and the outer surface not less.

IS

The connection of the nozzles with the pump and the location of the injection and suction nozzles allow the fuel to be directed tangentially, which creates an intense rotational movement in the electrocyclone.

The presence of the deceleration vanes allows one to quickly calm down after the acceleration of the fluid, which shortens the time of the working cycle, as a result of which the efficiency of the electric cyclone operation increases. FIG. 1 shows a device, a general view of $ in FIG. 2 - section A - A in fi 1. Charging devices 2 are diametrically mounted in the lower part of the case of the I electro-cyclone; they contain drives 3 for rotating disks A mounted on vertical shafts 5. One charging device has steel disks and the other has silver coated disks. Chargers are placed in the outer pockets 6. The discs 4 are placed in the pockets 6 in such a way that a portion of the Dusk enters the body by the amount D The body is equipped with a tangential discharge nozzle 7 and a suction nozzle 8, which are connected via a pump 9. The braking patches 11 are installed, kinematically connected by the levers 12 to the drive 13. The v-rim surface 14 of the blades II is made along the radius R equal to the distance from the center of the housing to the shaft 10 and the outer surface 15 must be at least R / 2. The operation of the electro-cyclone is carried out as follows. During the operation of the drives 3, the disks 4 rotate, which, due to the triboelectric effect, form electric charges. One charging device produces positive electrical charges, and the other, negative ones. At the same time, the pump 9 is turned on, which takes the electrolit from the cyclone through the suction inlet 8 and delivers it to the electrocyclone through the discharge inlet 7. Mixing together, the particles of the contaminants and the water coagulate into larger particles that are capable of precipitating under their own weight. After coagulation of soil particles and water in fuel, the rotational motion must be stopped. For a quick stop, the braking blades 1I are used. When the fuel is accelerated in an electrocyclone, they are placed in such a way as to minimize additional hydraulic resistances, for which the inner surface D is made along the radius R, and the outer surface must be at least R / 2. To stop the rotation of the fluid, the braking blades 1I are rotated by means of the actuator 1z and the lever system 12. At the same time, the vanes P direct the flow to the center of the coagulum and quickly begin to calm down due to the appearance of hydraulic resistance. Particles, contaminants, and water are collected at the center of an electro-cyclone and precipitate out, and then discharged from the reservoir. As a result of using the proposed electro-cyclone, the working efficiency is increased due to an increase in the hydrodynamic effect. Thanks to the reduction in time for acceleration and stopping the rotation of the fuel in the electro-cyclone by 25-40%, its productivity will increase by 20-30%. Claims of the invention 1.
