Definitions

  • the present invention relates to a fluid reclamation device for reconditioning fluids, typically lubricants, used in machinery such as vehicle engines or hydraulic systems.
  • Oil reclamation devices are already known which treat a bypass flow of oil and may work in tandem with a conventional full flow oil filter. Such devices for use in engines, motors, hydraulics, transmissions and the like are gaining in popularity because they can dramatically increase the time between oil changes.
  • the present invention relates in part to an oil reclamation device that has enhanced efficiency compared to conventional devices.
  • an evaporation head for a fluid reconditioning system comprising a heat diffuser plate and a cover together defining an evaporation chamber, and a heating element for heating the heat diffuser plate, in which the heating element is carried on or by the diffuser plate and in which the plate and cover are split and the plate is insulated from the cover.
  • a fluid reconditioning system comprising an evaporation head as described herein.
  • An oil cleaning system is provided for use on a wide variety of lubricating oils including synthetic and semi-synthetic.
  • the system effectively removes harmful contaminants and thus significantly extends oil service life.
  • the system will remove solid contaminants down to one micron in size and also has the ability to remove liquid and gas contaminants through an evaporation effect; as a result the build up of acidic contaminant is prevented. It has been shown that the use of the system will reduce oil consumption by 75% on engine applications and by greater than 90% on hydraulic applications, there is also a commensurate reduction in the consumption of full flow (standard) filters. Although filtration is an important part of any cleaning system, removal of solid particles is not sufficient. Evaporation is required to remove liquid and gaseous contaminants.
  • the system of the present invention works to two basic principles: - Filtration and Evaporation. It has become evident that while the filtration aspect is relatively well proven the evaporation capability required significant improvement and development; accordingly it is to this area that the patent application is directed. Specifically: the evaporation head removes liquid and gas contamination through allowing a thin film of oil to flow over a heated (evaporation) surface area. In effect the system ensures a comparatively small volume of oil flows over a (comparatively) large surface area thereby engendering the "thin film evaporation effect" which ensures rapid release of liquid and gas contaminants to atmosphere.
  • the filter typically comprises unbleached cotton. Not only does this provide a good physical particulate filter, but it also includes a protein which is easily attacked by acids, which helps with the chemical filtration.
  • the system may form part of a bypass system, a full flow system, or a combination of the two.
  • the current condition of the conditioned fluid can be monitored.
  • a sensor can be used to measure the dielectric constant (or relative permittivity) of oil. There is a close correlation between the oil dielectric constant and the oil quality (or deterioration). This information can be transmitted locally or communicated, for example electronically, to allow remote monitoring.
  • the heat diffuser plate may be generally frusto-conical.
  • the cover plate may be generally frusto-conical.
  • the plate may be insulated from the cover by a heat and oil resistant gasket.
  • the heating element may be an electric heating element.
  • the heating element may be encased in the diffuser plate.
  • the plate may be adapted to receive fluid from underneath in use, with fluid then flowing out over the heated evaporation surface.
  • the plate may include an annulus of orifices through which fluid can enter the evaporation chamber.
  • the cover may include a vent for releasing contaminants.

  • Figure 19 is a perspective view of a heat diffuser forming part of an evaporation head formed according to an alternative embodiment of development P5.
  • the evaporation head of the present invention has been developed to provide a significantly improved evaporation effect over existing systems.
  • the Research and Development Programme resulting in various embodiments of the present invention is detailed below.
  • FIG. 1 illustrates an evaporation head 10 formed according to the original embodiment-designated Pl .
  • the head 10 comprises a heat diffuser part 15 and a cover part 20 which when fitted together form an evaporation chamber.
  • the cover 20 is provided with a cylindrical casing 21 which houses a heater.
  • the heat diffuser 15 is provided with a plurality of inlets 16 in two diametrically opposed arcuate evaporation blocks 17.
  • the inlets 16 receive contaminated fluid so that it can flow over onto the outer surfaces of the blocks.
  • This embodiment is more efficient than known systems but ultimately inefficient in comparison to later developments due to minimal heat transfer from the heating element slots and a small evaporation surface area.
  • version Pl took greater than 48 hours to remove the water.
  • FIG. 2 to 4 illustrate an evaporation head 1 10 formed as the next stage of development - P2.
  • the oil passes through slots 122 next to an electric heater 121 and then flows over a frusto-conical plate 1 18 centrally positioned on the diffuser 1 15 to provide the evaporation effect.
  • This system removed the water contaminated as detailed above in approximately 36 hours.
  • an evaporation head 210 known as P3 was developed using a spiral oil flow channel pattern 223 around the heating element 221 (as illustrated in Figure 5 and 6). This embodiment was designed to increase the temperature of the oil by providing a larger surface area for the oil to flow through. However, there was no noticeable improvement in the system's ability to remove the water contamination (2% by volume in hydraulic oil as detailed above). This led to the conclusion that the key to effective evaporation was the heated surface area of the conical plate - therefore P 4 was developed as illustrated in Figures 7 and 8.
  • the evaporation head 310 is formed with a cover 320 and diffuser plate as an integral unit.
  • An oil inlet 319 is formed in a flow cylinder depending from the centre of the diffuser plate 315.
  • P5 was developed as shown in Figures 9 to 18.
  • the improved evaporation head 410 forms part of a reconditioning system 400 (as shown best in Figure 9) with a filter canister 440 and a casing 450.
  • the head 410 incorporates a split (in other words - formed separately) cover 420 and frusto-conical heat diffuser plate 415.
  • a heat and oil resistant gasket 455 is inserted between the two parts 415, 420 to insulate the plate from the cover.
  • the evaporation head 410 has an electric heating element 421 encased in aluminium which is shaped as a frusto-conical plate which in turns acts as the heated evaporation plate.
  • annulus of orifices 460 which give a controlled and measured flow of oil film over the heated surface 465.
  • the oil then exits the evaporation chamber via an outlet 471 and returns to the lubrication system by gravity.
  • Contaminated oil enters the unit through a restrictor 475 ensuring a slow, measured flow rate.
  • the oil passes through the replaceable filter element 440; the filter medium, consisting of compressed, unprocessed, long strand cotton removes solid contaminants down to one micron.
  • Oil then passes into the heated evaporation chamber 480 where liquid contaminants (e.g. water and volatile organic and inorganic compounds of fuel) and gaseous contaminants (e.g. sulphur dioxide) are evaporated and immediately vented - i.e. acid precursors are removed before they react to form harmful acids in the oil.
  • liquid contaminants e.g. water and volatile organic and inorganic compounds of fuel
  • gaseous contaminants e.g. sulphur dioxide
  • H2O + SO2 / SO3 H2SO4 : Water reacts with Sulphur Dioxide, Trioxide to form Sulphuric Acid.
  • the system removes H2SO4 components - Proactive, Pre-reaction.
  • the oil then flows back to the engine sump or hydraulic system by gravity.
  • Particulate size of less than one micron will not have an abrasive effect in an engine or hydraulic oil.
  • the system removes water and gas contaminants through the thin film evaporation effect present in the evaporation chamber acid formation is prevented - additives remain intact.
  • the system has similar benefits in hydraulic systems continuous evaporation of water.
  • a smaller version (known as P5 mini version) has been developed for smaller engines and hydraulic systems.
  • a diffuser plate 515 for this purpose is shown in Figure 19.
  • this version has been found to be particularly efficient when used in combination with the same heater used for larger versions.
  • the heater has the following characteristics: 24 volts; 150 watts; 6.25 Amps. This is used in conjunction with a slower restrictor: 20 litres/hour.
