Parallel Plate-type Electrodes Patents (Class 204/672)
  • Patent number: 9758392
    Abstract: A system combines complete, ultra-thin cells into a monolithic and robust framework necessary for desalination applications which yields orders of magnitude faster desalination. The electrode pairs are located so that a flow of feed water flows through or around the electrode pairs with the flow perpendicular to sequentially applied electric potentials. The system is controlled to charge the series of electrode pairs sequentially or phased. That means the charging of the second electrode pair is delayed with regard to the charging of the first electrode pair and the charging of a third electrode pair is delayed with respect to the charging of the second electrode pair.

    Abstract: A method and apparatus for separating drilling fluid is provided. A housing is provided with a number of vertical parallel spaced apart electrode plates within. The housing is filled with a batch of drilling fluid so that the drilling fluid fills up the spacings between the electrode plates and the drilling mud is subjected to an electro-separation cycle by placing a DC voltage across the electrode plates so that adjacent plates have opposite polarity and an electric field is created in the drilling fluid in the spacings between the electrode plates. During the electro-separation cycle, periodically subjecting the drilling fluid to a vibration cycle by inducing vibrations in the drilling fluid. When the treatment of the drilling fluid is completed, removing an upper layer of fluid from the housing.

  • Patent number: 8460532
    Abstract: The present invention provides a new method and apparatus/system for purifying ionic solutions, such as, for example, desalinating water, using engineered charged surfaces to sorb ions from such solutions. Surface charge is applied externally, and is synchronized with oscillatory fluid movements between substantially parallel charged plates. Ions are held in place during fluid movement in one direction (because they are held in the electrical double layer), and released for transport during fluid movement in the opposite direction by removing the applied electric field. In this way the ions, such as salt, are “ratcheted” across the charged surface from the feed side to the concentrate side. The process itself is very simple and involves only pumps, charged surfaces, and manifolds for fluid collection.

  • Patent number: 8377280
    Abstract: The present device is a microchannel separator that uses a separation driving force created by an electric field. An ionic fluid flows through the microchannels and is subjected to an electric field by two spaced apart parallel electrodes possessing an electric charge. The ions in the ionic fluid are attracted towards the charged electrodes and thus are concentrated in the region of flow near the charged electrodes and depleted from the central region of flow between the charged electrodes. The charged electrodes are insulated from the ionic fluid by an impermeable barrier which prevents arcing and adherence of the ions to the charged electrodes. After a sufficient length of passage of the ionic fluid through a main channel two blocking plates separate the flow into a central and two outer output channels. The central channel draws a portion of the ionic fluid from the central region of the main channel that has fewer ions than the ionic fluid in the regions near the charged electrodes.

The generated E-field can act upon a subject material, including a gas, liquid or solid, wherein the material is stationary or in motion.

  • Patent number: 7879216
    Abstract: An anode and cathode for an electrolytic cell configured as a low inductance transmission line to enable control of an interphase at an electrode surface. The anode and cathode are coupled to a switched current source by a low inductance path that includes a parallel plate transmission line, a coaxial transmission line, or both. The switched current source provides fast switching between current sources to provide fast charging and discharging of the double-layer capacitance associated with the electrode surface so that an isotope may be selectively transported to the electrode surface for oxidation or reduction. A photon source may be used to create a population of isotope containing species within the electrolyte. An additional static magnetic field and/or an alternating current magnetic excitation source may be used to modify the composition of the population of species containing the isotope to be separated.

  • Publication number: 20100108523
    Abstract: A vertical electrostatic coalescer comprises a first and second electrode surface and a horizontally disposed foraminous surface. The first electrode surface and horizontally disposed foraminous surface are at ground potential. The first and second electrode surfaces share the same planar orientation relative to the central longitudinal axis of the vessel. The unique arrangement of the vessel and opposing pairs of first and second electrode surfaces provides for a substantially uniform voltage field around a perimeter of the vessel and an effective voltage field for coalescence within a center of the vessel. A circular-shaped distributor pipe or a distributor housing serves to absorb momentum of the incoming emulsion stream and distribute the stream into an interior of the vessel.
