Definitions

  • the present invention relates to an exhaust gas purification technology and more particularly, to a method and system to purify the discharged gas of the exhaust pipe of a car, motorcycle or water heater, preventing air pollution.
  • a backpressure sensor may be installed in the exhaust pipe of a diesel engine to detect the pressure level of the waste gas in the filter element of the exhaust gas purifier, monitoring the status of deposition of carbon.
  • the backpressure sensor will detect a high level of back pressure, and the engine management system will give a signal to increase the working temperature of the diesel engine, thereby burning out cumulated carbon.
  • the ozone layer in the upper atmosphere filters potentially damaging ultraviolet light from reaching the Earth's surface.
  • Ozone is mainly located in the lower portion of the stratosphere from approximately 37 km to 74 km above Earth, though the thickness varies seasonally and geographically. Further, ozone is present in low concentrations (0.01 ⁇ 0.04ppm) throughout the Earth's atmosphere to prevent abnormal growth of bacteria.
  • CFC chloroflurocarbon
  • the Earth's surface temperature has raised 2oC when compared to the record 50 years ago. In consequence, the average environmental magnetic field has dropped from the early 0.5 Gauss to the present 0.45 Gauss.
  • waste gases are bad ozone produced after a chemical reaction that is a pollutant that is a significant health risk, especially for children with asthma.
  • discharged waste gases from vehicles produce much bad ozone.
  • Repeated exposures to 125ppb ozone enhance bronchial allergen responses. Exposure to ozone also causes deterioration of rubber and plastic products.
  • ozone is a triatomic molecule consisting of three oxygen atoms, having many industrial and consumer applications. When compared to chlorine or cresol, ozone shows a better result in bacteria killing.
  • bacteria are single-celled microorganisms which can exist either as independent (free-living) organisms or as parasites (dependent upon another organism for life).
  • Bacterial particles consist of protein, polysaccaride and lipids.
  • virus is a small infectious agent that can replicate only inside the living cells of organisms.
  • Virus particles consist of genes made from either DNA or RNA, long molecules that carry genetic information; a protein coat that protects these genes, and in some cases an envelope of lipids that surrounds the protein coat.
  • Ozone can penetrate bacteria and virus, causing them to be changed into enzyme. Thus, RNA can be decomposed, and DNA can be destroyed.
  • Ozone can be decomposed into 02 molecules and oxygen atom.
  • Ozone's deodorizing action is a chemical destruction of the compounds that create the odors
  • Ozone deodorization is extremely effective for more serious odor.
  • Ozone is highly reactive and combines with malodor molecules to chemically alter their structure and rid property of odor.
  • Ozone also kills bacteria and fungi and works as a sanitizing agent.
  • negative ions have the functions of:
  • the present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide an exhaust gas purification method and system, which effectively purifies the discharged gas of the exhaust pipe of a car, motorcycle or water heater, preventing air pollution. It is another object of the present invention to provide an exhaust gas purification method and system, which utilizes ozone and/or negative ions to decompose toxic substances in waste exhaust gas, avoiding carbon monoxide poisoning.
  • an exhaust gas purification method is to connect an ozone/negative ion generator to a power source electrically by an electric wire, and then to connect the ozone/negative ion generator to a waste gas exhaust pipe having a waste gas inlet and a waste gas outlet by a connection pipeline, and then to turn on the ozone/negative ion generator to generate ozone/negative ions upon flowing of a flow of waste gas from the waste gas inlet of the waste gas exhaust pipe toward the waste gas outlet.

  • the vehicle engine exhaust pipe 6 is connected with a muffler (not shown) for the discharge of engine waste gas.
  • the negative ion nozzle head 3 comprises a flange 31 affixed to the peripheral wall of the vehicle engine exhaust pipe 6, a heat resistant insulation 33 wrapped about the periphery thereof and a nozzle tube 32 suspending inside the vehicle engine exhaust pipe 6.
  • the heat resistant insulation 33 can be prepared from ceramic, stainless or any other heat resistant material.
  • the negative ion generator 4 starts to generate negative ions upon connection of high voltage electric current.
  • the generated flow of negative ions is discharged through the nozzle tube 32 into the inside of the vehicle engine exhaust pipe 6.
