The invention relates to the oil industry and can find application in the processing of oil sludge.A device for breaking oil-water emulsions, including K and high-frequency generator, connected with the pipe (USSR Author's certificate 700163, publ. 30.11.79).The known device does not provide a sufficiently high degree of loss of stability of oil-water emulsion.Closest to the invention to the technical essence is a device for breaking petroleum emulsions comprising a vertical housing with connections to the I / o emulsion, which is the outer grounded electrode, a Central coaxial electrode made in the form of alternating sections of metal and a hydrophobic dielectric, and a capacitor connecting each subsequent section of the Central electrode with each of the previous section (USSR Author's certificate 1105213, publ. 30.07.84 prototype).The known device not effectively destroys oil emulsion, especially an oil sludge, due to the fact that the device does not have the ability to customize the resonance, which is necessary for processing of oil sludge.The invention solves the problem of increasing the efficiency of separation of oil sludge into oil and water.The task is solved in that the device for processing of oil sludge, comprising a housing with a pipe and a condenser according to the invention provided with inlet ele is rpusa metal tube, having in the lower part of the vertical slit and the outlet water outlet and connected at the upper part with the lower disk capacitor and connected in the lower part through the insulator and the metal faceplate to the body, and a probe connected to an electric communication with the electronic device, managing reversible electric motor drive, with a metal faceplate is installed with the possibility of vertical movement and connected with the reversible drive motor, and drives the condenser is made of metal with holes for the passage of oil.The drawing shows a device for processing of oil sludge.The device includes a housing 1 in the form of metal tubes of variable diameter, a flat capacitor formed by the upper 2 and lower 3 disks placed in the insulator 4, and located along the axis of the housing 1 metal tube 5. The housing 1 is equipped with nozzles enter the oil sludge 6, output oil 7 and air vent 8. In case 1 posted by the temperature sensor 9 and the probe 10 connected electrical communication with the electronic device 11, which in turn is connected to a reversible electric motor 12. To the upper disk 2 in the insulator 13 is a supply of electromagnetic energy which is made of metal, round, with openings 15 for the passage of oil. Metal tube 5 from the bottom through the insulator 16 and the metal faceplate 17 is connected to the housing 1. Metal tube 5 in the lower part has a vertical slit 18 and the outlet water outlet 19. Metal faceplate 17 is installed with the possibility of vertical movement and connected to the actuator 20 and a reversible electric motor 12.The device operates as follows.Through the pipe 6 into the housing 1 enter the oil sludge. To the upper disc 2 flat condenser through inlet 14 from a high-frequency generator serves electromagnetic energy. The lower disk 3 and the metal tube 5, a metal faceplate 17 and the housing 1 perform the role of second capacitor plates. Inside the housing 1 is exposure to high frequency electromagnetic fields to oil sludge. Due to the different resonant electrothermomechanical process is the separation of oil sludge into water and oil. The oil passes through the holes 15 of the upper 2 and lower 3 disks and discharged through the pipe o oil 7. Emitted gases and the air is discharged through the outlet pipe of the air 8. Water gets into the slit 18 of the metal tube 5 and discharged through the pipe is established by changing the position of the metal faceplate 17. The probe 10 in the high-frequency electromagnetic field induces an electric current. The current strength varies depending on the settings of the device at resonance. The signal from the probe 10 is supplied to the electronic device 11, which controls the reversing motor 12. From the reversible motor 12 through the actuator 20, the movement is transmitted to the metal faceplate 17. Moving up-down, metal faceplate 17 changes the length of the resonance chamber. At a certain position of the metal faceplate 17 comes resonance oscillation in which the separation of oil sludge on the oil and water is most effective.The insulators 4, 13 and 16 are made of PTFE. The temperature sensor 9 is used to control the temperature in the housing 1.Application of the proposed device will allow you to split trudnootdelemy oil sludge and thereby contribute to the reduction of environmental pollution.
