Such as, centered by TWH8751, the pulse oscillation circuit composition negative oxygen ion generator of device, can obtain the high pressure of about 20kV T level.2. when the pin of TWH8751 and in-phase input end are high petential, the blocking of oscillator, when not powering, between A, B, resistance is very large, and B point current potential is very low, and the 2. pin of TWH8751 is high petential, and oscillator does not work, and does not have negative ion to produce; During power supply, the 2. pin of TWH8751 is low potential, oscillator starting of oscillation, produces negative oxygen ion.Negative ion generator is discharged by negative ion release end 12, and ionized air produces a large amount of free electron e-, and these free electrons are captured by the oxygen molecule in air and form negative aeroion, thus " release " goes out negative ion.Discharge end adopts open, reduces the concentration of ozone, and the oxygen molecule allowing major part originally can become ozone because of ionization captures free electron becomes negative ion, thus forms large-scale negative ion, substantially increases the concentration of negative ion.
Preferred negative ion release end 12 comprises negative high-voltage end carbon fiber brush release end 12.
Negative ion release end 12 also can adopt metal tip to discharge end 12.
Negative ion release end 12 is positioned in automobile tail outlet pipe 2, or is placed in before outlet pipe 2, or is placed in vehicle exhaust air outlet place.
According to a kind of purifying vehicle exhaust process vent systems of the method development, comprise electronic high voltage negative ion generator 1, outlet pipe 2; The negative ion release end 12 of electronic high voltage negative ion generator 1 is positioned in automobile tail outlet pipe 2, or is placed in before outlet pipe 2, or is placed in vehicle exhaust air outlet place.
Difference between a kind of electronic high voltage extensive negative ion automobile exhaust gas cleaner mentioned above and a kind of purifying vehicle exhaust process vent systems is, the former is a kind of device, be installed at existing automobile exhaust pipe 2 port, realize the exhaust gas purification to existing automobile; The latter transforms whole automobile exhaust system, or newly design as the one of automobile exhaust system, the release end 12 of electronic high voltage negative ion generator 1 is directly placed in outlet pipe 2, outlet pipe 2 outlet port or between motor and outlet pipe 2, realize the purification to vehicle exhaust.
Compared with prior art effect of the present invention:
After adopting extensive negative ion automobile exhaust gas cleaner, this device changes corona discharge conditions, the oxygen molecule in air is suppressed to generate ozone because of ionization, make the oxygen molecule in air as much as possible capture free electron and become negative ion, thus obtain large-scale negative ion, rolling up of negative ion, neutralize with the gas molecule of positively charged in vehicle exhaust, formation solids particles precipitate gets off, be not released in air, purifying effect is remarkable, can meet the requirement of purifying vehicle exhaust, make tail gas reach emission standard completely.
Use of the present invention, to the pollution preventing vehicle exhaust to environment, the harm of harmful matter to health reduced in vehicle exhaust has positive meaning.
