Definitions

  • the present invention relates generally to an apparatus and method for treating exhaust gases, and more particularly to a combustion engine treatment device for removing and/or reducing pollutants contained in the combustion engine effluent gases.
  • the present invention reduces carbon dioxide, substantially reduces hydrocarbons and virtually eliminates the exhaust of carbon monoxide.
  • Electrostatic precipitation is widely used in such applications and involves the application of high voltages to electrodes positioned in the exhaust gas stream. This process induces ionization of gas particles, which in turn cause particulates suspended in the gas to acquire a charge from contact with the ionized gas particles. The charged particles are then collected at oppositely charged diodes, which must be eventually "cleaned” or "scrubbed".
  • a significant drawback of electrostatic precipitation is that only minute particulate matter can be precipitated out of the exhaust stream. The process is ineffective at removing gaseous contaminants such as carbon monoxide and carbon dioxide.
  • US 5,733,360 discloses a corona discharge reactor and corresponding method for chemically activating the constituents in an exhaust gas stream by use of corona discharge.
  • the reactor includes within a conduit a discharge plate having a plurality of through openings and a plurality of projecting corona discharge electrodes and an electrode plate having a plurality of through openings displaced from and opposing the tips of the corona discharge electrodes.
  • a pulsed energization scheme is employed to intermittently generate a uniformly distributed corona discharge cloud between the plurality of corona discharge electrode tips and the electrode plate during passage of the gas stream through the conduit.
  • the short durations of voltage application are chosen to suppress the formation of sparks across the gap.
  • the gas flowing through each flow passage is proximally and concurrently exposed to a plurality of such corona discharge points, where electron energy levels are high, so as to realise the occurrence of oxidation, reduction or other chemical activation of the constituents in the gas stream.
  • electrodes in the form of elongate, parallely arranged rods are forming an ignition module for igniting components in an exhaust stream which are not fully combusted, such as in two-cycle internal combustion engines.
  • the electrodes in each grate are oriented such that their central axes are parallel and substantially coplanar to adjacent electrodes within the same grate.
  • the grates are substantially parallel, but the central axes of the electrodes of one grate being perpendicular to the axis of the electrodes of the opposing grate to create a lattice-type electrode configuration.
  • a cascading electrical arcing pattern and distribution among the nodes formed between various electrodes is controlled by a spark generating module which includes a computer module to appropriately modify arcing variables such as voltage and switching frequency between the electrodes in the respective grates.
  • the combustor is not intended for reducing hydrocarbon and volatile organic compound emissions from the exhaust stream.
  • Burners, activated carbon and water curtains are widely used to reduce hydrocarbon and volatile organic compound emissions.
  • these pollution control devices are impractical for use with internal combustion engine vehicles.
  • a significant drawback of burners and water curtains is a large operation cost and activated carbon is easily clogged when treating a particulate laden air stream.
  • Masters, U.S. Patent 5,419,123 discloses an emission control device and method for treating exhaust gases to reduce pollutants contained therein.
  • the device includes a treatment chamber having a first metal screen, a second metal screen and a perforated chemical substrate disposed between the first and second metal screens.
  • An electrode disposed a distance from the first screen and is applied a voltage so that sparks are generated between the electrode and the first screen.
  • the Masters patent may reduce emissions in the exhaust gas it has several limitations. Since an electrode is used to deliver the spark the electrified area is concentrated to a portion of the first screen and hence is not evenly distributed over the entirety of the screen. Consequently, a portion of the gas stream is not sufficiently treated. This problem become more pronounced if the plug becomes angled towards or away from the first screen.
  • the present invention provides an apparatus and method for reducing or eliminating emissions from a gas stream.
  • the gas stream is treated by a treatment chamber in series with a second chamber having perforated strata.
  • the treatment chamber includes a first metal grid supplied with high voltage and a second metal grid grounded to the treatment chamber to generate sparks over the entirety of the first grid to the second grid thereby causing electronic ionization. Since all of the air stream is required to flow through the first and second grids, all of the air stream is fully treated.
  • the second metal grid is conductively connected to the second chamber and, therefore, the entire connection and the second chamber are also electronically ionized. Due to the treatment caused by electronic ionization the strata can fully perform with significantly less use of noble metals than with conventional catalytic converters. Although maximum pollution reduction occurs with the use of about one 3 g (1/10 troy ounce) of platinum, rhodium, or palladium, favorable results are achieved without the use of any noble metal.
  • a further advance is a high efficiency induction coil.
  • the coil applies voltage from a source to the first screen at an efficiency of at least eighty percent thereby causing very hot sparks between the first grid and the second grid. Additionally, this coil is configured to dampen the magnetic field created by the induction coil. Dampening the magnetic field is particularly important in automotive applications and other applications which are integrated with a computer since the magnetic field can create random cycling current in the electrical system so as to cause false signals to be sent to the computer.
  • the present invention substantially reduces carbon dioxide and hydrocarbons and virtually eliminates the exhaust of carbon monoxide.
  • the system can be used to treat emissions from industrial effluent stacks, spray booth, styrene manufacturing, burning hazardous waste, purifying air streams among a variety of other industrial processes, and is particularly useful for treating emissions from the combustion of carbon or fossil fuels.
  • the system can be installed as original equipment, an add on device or as an after market device.
  • the principal object of the present invention is to provide an improved apparatus and method for reducing pollutants from a gas stream.
  • the apparatus includes a first body form a first chamber. First and second metal girds are fixed within the first chamber so that the gas stream entering the first chamber passes through the grids.
  • An electrical connector is attached to either the first grid of the second grid and connects that grid to a voltage source causing electrical sparks to be generated between the first grid and the second grid.
  • a pulsing mechanism pulses the applied voltage at a predetermined frequency.
  • a second body forming a second chamber has a perforated strata through which the gas stream flows.
  • Another object of the invention is to provide a voltage difference between the first grid and the second grid of at least 20,000 volts. Additionally, the pulsing mechanism is capable of pulsing the voltage at a frequency of greater than 1,600 pulses/minute.
  • a further object of the present invention is to fix the nearer of the first or second grid a distance between 2.54 cm (1 inch) and 30.48 cm (12 inches) from the strata. Additionally, another object is to space the first grid from the second grid a distance between 0.635 cm (1/4 inch) to 2.54 cm (1 inch).
  • Another object of the present invention is to use an electrical connector which is adapted to apply at least 80 percent of the voltage the connector receives.
  • a further object of the present invention is to for the electrical connector to include a plurality of bare wires juxtaposed in a first curvilinear row and coiled equal-distantly about a curvilinear centerline thereby forming a curvilinear helix shape.
  • a plurality of insulated wires are juxtaposed in a second curvilinear row and coiled around the bare wires.
  • An insulated center-wire is positioned along the curvilinear centerline and disposed within the bare wires and the insulated wires.
  • Another object of this invention is to provide a method of treating exhaust gasses to reduce pollutants contained therein.
  • the method includes the steps of passing exhaust gasses through a first body forming a chamber.
  • the gasses are passed through a first grid and a second grid fixed within the chamber.
  • the grids are separated a predetermined distance from each other.
  • Voltage is supplied from a voltage source to either the first or the second gird to generate sparks between the first grid and the second grid.

  • the exhaust gasses also pass through a strata.
  • a further object of the invention is to provide a voltage difference between the first grid and the second grid of at least 20,000 volts at a frequency of at least 1,600 pulses/minute.
