Abstract
The invention provides the technological scheme of a kind of method of purifying exhaust gas from internal combustion engine and purifier.Existing internal-combustion engines exhaust gas purifying technology is to add fixed filter or catalyst converter behind tailpipe, the internal-combustion engine that inapplicable fuel oil is leaded, and purifying effect is undesirable.The purifier that the present invention uses gaseous discharge physical method and this method of realization can efficiently purify the engine exhaust gas of various fuel oils, applies and will bring very big social economic benefit.
Description
The invention belongs to general physics or chemical method and device, a kind of method of purifying exhaust gas from internal combustion engine and purifier.
Contain CO, HC, nitrogen oxides and carbon granules in the waste gas that internal-combustion engine is discharged, befouling environment, harm humans health, for this reason, people work out the whole bag of tricks to eliminate or to alleviate this pollution.Diesel engine generally uses filter, allows soot be deposited on filter surfaces, but can not make carbon granules be converted into the innoxious compound of gaseous state; Gasoline, natural gas internal-combustion engine are installed the catalytic cleaner that is added with small amounts of platinum in tailpipe, the molecule that is in the state of activation in the harmful gas is quickened to the chemical reaction that is converted into innoxious substance, to reduce noxious pollutant in the waste gas, but this method can not increase the molecule number that is in the state of activation, thereby it is very limited to fall dirty effect, and this technology can only be applied to the internal-combustion engine of unleaded gas, otherwise the lead compound in the waste gas can make catalyzer " poisoning " inefficacy ".
The purpose of this invention is to provide exhaust gas purifying method and purifier that the internal-combustion engine of various fuel all is suitable for.
Purpose of the present invention realizes by following method of purifying exhaust gas from internal combustion engine and purifier scheme.The mechanism of this purification method is to produce high-energy electron with the physical method of gaseous discharge will not be in the molecule " activation " of the state of activation in the waste gas, make not the gas generation activation and the ionization of complete reaction, obtain participating in the activation energy that chemical reaction need have, thereby increase the molecule number that is in the state of activation in the waste gas greatly, harmful matter is accelerated greatly to the chemical reaction velocity of harmless conversion, reached the more effectively purpose of purifying exhaust air.Purifier provided by the invention is exactly a device of realizing this purification method, and it is made up of main frame, high-voltage insulating wire and discharging electrode.After the rectification circuit rectification, deliver to discharging electrode by the high pressure that trigger circuit, vibrator circuit, power amplification circuit, booster circuit work produce by high-voltage conducting wires, its power circuit is controlled by the internal-combustion engine ignition switch, discharging electrode is made of central metal spray point and ceramic coat thereof, and the discharging electrode seat is provided with the assembling screw thread so that assemble with tailpipe.For preventing that puncturing the waste gas sparkover causes wireless to pollute, dress one deck garden column type pottery thin-walled in tailpipe.
Fig. 1 is this purifier electricity functional-block diagram and summary figure.
Fig. 2 is this purifier scheme of installation.
Description of drawings: 1. trigger circuit, 2. vibrator circuit, 3. power amplification circuit, 4. booster circuit, 5. rectification circuit, 6. discharging electrode, 7. power circuit, 8. tailpipe, 9. main frame, 10. platinum-carryin catalyst, 11. internal-combustion engine, 12. gas exhaust manifolds, 13. silencing apparatuss, 14. high-voltage insulating wires.
The invention will be further described with three embodiments below:
1. be applied to the doped fuel internal-combustion engine.Main frame 9 is installed near the internal-combustion engine 11 the support, and discharging electrode 6 adopts screw-thread fit to be connected with tailpipe 8.Internal-combustion engine ignition work simultaneously, the main frame trigger circuit make vibrator circuit work, the high pressure of oscillator signal after power amplifier, the rectification of boosting is added to and produces electrion on the discharging electrode, with emission molecule ionization, the activation in the tailpipe, thereby strengthen greatly and quicken the chemical reaction that harmful matter is converted into innoxious substance.
2. be applied to the internal-combustion engine of unleaded gas and rock gas.With above-mentioned different be to be connected in series platinum-carryin catalyst 10 behind the discharging electrode in tailpipe.Like this, under activation, catalysis acting in conjunction, make the molecule that has activation energy in the tail gas more, simultaneously also reduced the required bottom line energy of chemical reaction, further improved chemical reaction velocity, made in the waste gas harmful matter carry out more fully to the chemical reaction of harmless conversion.
3. be applied to the diesel engine waste-gas cleaning.With the use that is combined as a whole of purifier discharging electrode and catalytic cleaner, under the ionization and activation of high-energy electron, the carbon granules in the tail gas, oxygen and nitrogen oxides increase activation energy; Simultaneously, under the catalyst converter effect, carbon granules and oxygen and nitrogen oxides have the required activation energy that has of the chemical reaction of participation, and chemical reaction takes place, and generate harmless CO
2And nitrogen, thereby reach purification.
The invention has the advantages that and do not change various Structures of Internal-Combustion Engine in the practicality fully. The performance of combustion motor, use and reliability do not have impact. Leaded, the lead-free internal combustion engine of fuel oil no matter, the harmful substance in the toxic emission can both purify efficiently.
