Description

 The invention relates to engineering and technology and can be used for refining industrial oils.

 Known electrostatic filtering device [1. Germany C1, PS 42165825 B 03 C 5/02, B 01 D 35/06, 93.12.02 48].

 The effectiveness of this device is limited by the impossibility of creating high voltage due to the presence of uninsulated parts of electrodes of opposite signs.

 Known electric separator substances of suspensions [2. Pat. RF 2058828 C1, 6 V 03 C 5/02, 04/27/96. Bull. 12], comprising a housing in which inlet and outlet openings are arranged horizontally arranged one below the other in vertical rows, insulated electrodes connected to a voltage source.

 This device allows you to create high tension. The absence of bipolar electrodes without insulation in this device does not allow changing the ionic composition of the suspension, which does not allow changing the ionic composition of industrial oil.

 A known apparatus for separating and removing particles suspended in a liquid [3. P.M. RF 13620, 7 B 03 C 5/02, 05/10/2000. Bull. 13, prototype], comprising a housing in which inlet and outlet openings are arranged horizontally arranged one below the other in vertical rows, insulated electrodes connected to a voltage source, according to the invention, three outlet openings are placed in the lower part of the housing between two vertical rows of electrodes and on the opposite sides of the rows of the latter, and the inlet is located in the upper part of the housing between the vertical rows of electrodes connected in order to the terminals of different polarity of the source voltage, the zero clamp of which is connected to the housing and is grounded.

 This device separates particles into three parts: particles that carry a positive charge, particles that carry a negative charge (including small drops of water) and neutral particles, and also improves productivity.

 But the device also does not allow to significantly change the ionic composition (reduce acidity) in industrial oil.

 The basis of the invention is the task of expanding the functionality of the device when cleaning industrial oils, i.e. simultaneous removal of particles carrying a positive charge, particles carrying a negative charge (including water), neutral particles, reducing acidity and increasing the productivity of the apparatus.

 To do this, in the apparatus for cleaning industrial oils, containing a housing in which there are inlet and outlet openings horizontally arranged one below the other in vertical rows, insulated rod electrodes connected to a voltage source, three outlet openings are placed in the lower part of the housing under a row of electrodes and on the opposite sides of the row of electrodes, and the inlet is located in the upper part of the housing above the electrodes equipped with insulation, connected in order to the clamp of the voltage source, with According to the invention, spiral electrodes without insulation are connected to the electrodes on top of the insulation, connected to the grounded terminal of the voltage source, on both sides of the electrodes are placed separation grids fixed in the grounded case, a plate electrode connected to the third terminal of the voltage source is placed between the rows of electrodes.

 The design of the electrodes allows to reduce the acidity of industrial oil due to electrolysis on non-insulated electrodes while maintaining the ability to separate polarized and charged particles using isolated electrodes, which are supplied with high voltage, and separation grids. In addition, the productivity of the apparatus is further increased by increasing the electric field between the electrodes, including edge effects between extremely close spiral electrodes and insulated electrodes.

 This design allows you to divide the flow into three parts: waste comes from the middle outlet, and refined oil comes from the extreme exits.

 The drawing shows the location of the electrodes in the housing in the context and a diagram of their connection to a voltage source.

 The apparatus comprises a housing 1, equipped with an inlet 2 and drain holes 3, 4 and 5. In the housing 1 are placed horizontally arranged electrodes 6 one above the other in parallel vertical rows, provided with insulation 7, connected to the first terminal 8 of the voltage source 9. On the electrode 6 equipped with insulation 7, a grounded electrode without insulation is placed in the form of a spiral 10. Between the rows there is a plate electrode 11, which is connected to the second terminal 12 of the voltage source 9. The third terminal 13 of the voltage source 9 is connected to the housing 1 and earthly. The housing 1 is equipped with a separation grid 14.

 The device operates as follows.

 When a voltage source is connected, an electric field is created between the insulated electrodes 6, the spiral electrodes 10 on the one hand and the plate electrode 11, the separation grid 14, the housing 1 on the other hand, and also between the insulated electrodes 6 and the spiral electrodes 10. Into the housing 1 through the inlet 2 oil enters. Particles carrying a positive charge are attracted to the plate electrode 11. Negatively charged particles are attracted by insulated electrodes 6, to which a high pulse voltage is applied. The impulse voltage “shakes” the particles. Crude oil flows out through hole 4. In this case, gravity contributes to the movement of all particles. Non-insulated electrodes 10 and plate electrode 11 alter the ionic composition of the suspension. Refined oil flows through separation nets 14 and outlets 3 and 5.

 The device is characterized by high efficiency in the extraction of particles and water. At a water content of 0.03% after purification, there is no water.

 The installation is characterized by a relatively low consumption of electric energy, since the electrostatic field of the isolated electrodes is used; several rows of electrodes can be made in one housing.

 The invention is intended for the separation of suspended particles in a liquid and may find application for the purification of industrial oils, chemical, enrichment industry, for the use and elimination of environmentally harmful waste and dumps, for the purification and disinfection of water, for cleaning the earth from harmful substances.
