RU102905U1 - SUPER-DEEP CLEANING AND REGENERATION OF ENERGY OILS - Google Patents

Abstract

 Ultra-deep cleaning and regeneration scheme for energy oils, characterized in that a metering unit, a reactor with a heating element and a stirrer, coarse filters, a turbo dryer and electrostatic ultra-deep filters are installed in series in the drain part of the oil tank to restore the performance properties of energy oils.

Description

The proposed utility model relates to the field of energy and can be used for super-deep cleaning and regeneration of energy oils.

There are various schemes for cleaning and regenerating energy oils (1, 2, 3). The circuit consists of a cylindrical housing, a set of electrostatic filters inserted in a cylindrical package, a pump for oil supply and a control panel.

The oil being cleaned is fed into a cylindrical housing with electrostatic precipitators located in it. Contaminants settle on the inner surfaces of electrostatic filters in the cells of the drives and are retained in them.

Another cleaning scheme is an experimental installation for cleaning fuels and lubricants (4), consisting of an electrostatic precipitator, a casing, and a pump. Oil is passed through an electrostatic field, in which polar particles are deposited on the electrodes that create this field (electrophoresis process), and neutral particles, due to a special element (corrugated paper) located between the electrodes, which distort the electric field, settle on this element in places of greatest tension (electrophoresis). This device does not contain any filters and the flow rate does not fall and, accordingly, does not create high pressure. At the same time, small particles (from 0.8 μm, oxidation products) are removed from the oil, which cannot be achieved using porous filters.

The disadvantages of the prototypes:

- the need for preliminary oil purification, since in the presence of moisture a short circuit of the package of electrostatic precipitators can occur;

- the inability to use with significant contamination of oils (particles of 20-50 microns, because many particles are conductors, which can lead to the closure of the package of electrostatic precipitators);

- the inability to reuse production oil in the development of one or more additives.

The purpose of the proposed utility model is to increase the reliability and efficiency of regulation and control systems, to increase the service life of equipment and operating oil.

The utility model includes a description and a schematic diagram of ultra-deep cleaning and regeneration of energy oils (figure 1).

The circuit consists of an inlet pipe 1; oil supply pump 2; electromechanical valves with a return mechanism 3, 29; coarse filters 4, 5; hydraulic crane with electric motor 6, 7; ultra-deep electrostatic filters 8, 9; chokes with a constant geometry of 10, 11, 12; drain valves 13, 14, 15, 16, 17, 18; turbo dryer 19; compressor 20; a pump for pumping oil from the desiccant 21; gas separator 22; output pipe 23; a flow meter 24; check valves 25.26; dispenser unit 27; a reactor with a heating element 28; to obtain a concentrated additive solution.

To ensure reliable operation of electrostatic ultrafine filters 8, 9, oil is supplied through a flow meter 24 and inlet pipe 1. Pump 2, through an electromechanical valve 3 with a return mechanism, supplies oil to coarse filters 4, 5, which are designed to separate coarse particles of contaminants and free water. From the coarse filters 4, 5, the oil is supplied for drying to the turbo dryer 19 through an electromechanical valve 6. In the turbo dryer, the oil is fed through a constant-flow inductor to the atomizer distributor, where water is removed from the oil.

An automatic level maintainer and a water trap provide separation of the oil-air emulsion and the release of moisture along with air into the atmosphere. The air necessary for the implementation of the process is supplied to the system using a centrifugal compressor 20 mounted on a water seal.

The drained production oil is pumped out of the hydraulic trap using a pump 21 and fed to the gas separator 22 for degassing. The final separation of air microparticles takes place in the gas separator.

Further, the oil through superfine electrostatic filters 8, 9, designed to remove microparticles of contaminants (particle size from 0.1 μm) is fed back to the oil-filled equipment through the outlet pipe 23 and check valve 26. The contaminants on the inner surfaces of the oil-filled equipment diffuse into the cleaned one way oil and removed from it.

The proposed model provides a scheme for the preparation and introduction of mandatory additives to adjust the consumer properties of the oil.

For this, a dispenser unit 27 is installed in the drain part of the oil tank. Additives are fed into the reactor 28 with a heating element and a stirrer. The concentrated additive solution through the check valve 25 is fed to recycling. Upon receipt of the finished concentrate, an electromechanical valve 29 with a return mechanism opens and the concentrate is fed through the flow meter 24 to the coarse filters and then to the electrostatic ultrafine filters.

The advantage of the claimed model, in comparison with the prototypes, is that oil purity is achieved far from the level of saturation of contaminants, as a result of which the contaminants diffuse from the internal surfaces of the oil-filled equipment and are removed through the accumulator of pollution. In addition, a concentrated solution of additives is obtained, introduced into the oil system and redistributed in the base oil. This increases the life of the oil and increases the service life of the equipment.
