See also Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model diesel engine electronic filter cigarette three-way catalytic converter, it is mainly by three-way catalytic converter 1, and metal electron sieve 2 is housed in three-way catalytic converter, metal electron sieve 2 be connected with static emitting circuit 3 form.Wherein: three-way catalytic converter 1 is to be made up of Stainless Steel Shell 4, vibration damping sealing gasket 5 and catalyst 6 successively.Metal electron sieve 2 is by Stainless Steel Shell 4, vibration damping sealing gasket 5, catalyst 6, be respectively equipped with positive and negative electric charge Stainless Steel Cloth 7,8 in catalyst 6 both sides, electrode column ceramic insulation sleeve and electronics sieve fixture 9, two electrode columns are housed at Stainless Steel Shell 4 two ends connect positive and negative electric charge Stainless Steel Cloth formation respectively.Static emitting circuit 3 is to be connected to form successively by power supply, 555 time-base integrated circuit IC, driving tube GB, transformer B and voltage multiplying rectifier eliminator.It is 409 thick type stainless steels of 1.5mm that Stainless Steel Shell 4 adopts, and its thermal expansion coefficient and catalyst are complementary.
The circuit working principle:
The elementary process that static transmitter 3 and metal electron sieve 2 are handled diesel engine carbon black is: after engine start work, static transmitter 3 power supplys both had been switched on and had launched the static that has positive and negative electric charge respectively to two metal electron sieves 2, adding a catalyst 6 between two metal electron sieves 2, between metal electron sieve 2 and Stainless Steel Shell 4 surface of contact, adding isolation layer, power up the static electric field that the back forms 1000V.At this moment, diesel engine institute exhaust gas discharged arrives metal electron sieve 2, carbon soot particles just is being endowed (or negative) electric charge under electric field action, and under the attraction of the metal electron sieve 2 that promotion and next piece of exhaust back pressure has negative (or just) electric charge, sieves 2 surface impacts to next piece metal electron.The carbon soot particles of (or negative) electric charge strikes the moment that next piece has the metal electron sieve 2 of negative (or just) electric charge when above-mentioned just having, because the bump of positive and negative (or negative, positive) electric charge produces fierce electric discharge phenomena and high-octane heat energy, most carbon soot particles are fully burnt, and the burning back produces carbon monoxide (CO) and carbon dioxide (CO 2); Wherein carbon monoxide (CO) is the handled object of rear end catalyst just, carbon dioxide (CO 2) then directly discharge, the carbon soot particles work of treatment is promptly accused and is finished.
Static transmitter 3 circuit theory diagrams are as shown in Figure 3: the power supply of this static emitting circuit derives from the automobile storage battery that voltage is 24V, power switch K 1Link to each other with automobile starting switch, when the driver starts vehicle, can connect this power supply, the static emitting circuit is started working; Utilize 555 designed type time base circuits (this circuit is 15KHZ for no equilibrium mode, oscillation frequency), its 3rd pin is through R 3Drive the admittance of triode BG1 and end, thereby inferior utmost point on boosting transformer B produces ac high-voltage, forms 1000V high voltage direct current static and export behind rectifying and wave-filtering.Making this static transmitter can make and must carry out in strict accordance with component parameter and requirement that accompanying drawing provides as need, to guarantee safe handling voluntarily to the customization of domestic and international specialized factory.
Metal electron sieve 2 is made by special Stainless Steel Wire braiding, and positive charge electrode column 10 is connected positive charge Stainless Steel Cloth 7 and negative charge Stainless Steel Cloth 8 with negative charge electrode column 11; Electrode column ceramic insulation sleeve and fixture 9 are inserted by Stainless Steel Shell 4 surface punchings, after sealing with high temperature resistant binding agent docking port slit, between positive charge electrode column 10, negative charge electrode column 11 and three-way catalytic converter 1 stainless steel casing 4 threes, just formed an isolation layer; Fix the rigging position of positive and negative electric charge Stainless Steel Cloth 7,8 simultaneously, thereby make it closely contact the purpose that realizes being maintained fixed the position with catalyst 6, working principle powers up back chance carbon soot particles and promptly begins to produce electrocaloric effect as mentioned above.Double-level-metal electronics sieve structure of the present utility model is to be that fundamental mode designs with the motor of discharge capacity below 4 liters (L), but static-generator can provide static to quadruplet electronics sieve simultaneously, and the motor that discharge capacity surpasses 4 liters (L) can be designed to the multilayer electronic sieve structure.
Explanation to catalyst: (catalyst claims three-way catalytic converter again)
Catalyst is handled oxynitrides (NO X), carbon monoxide (CO) and hydrocarbon (HC) wait the elementary process of other harmful gases to be: catalyst is by platinum (Pt), palladium (Pd), rhodium precious metal material and auxiliary material such as (Rh), be mixed with the precious metal composite catalyst according to certain ratio, be coated on the honeycomb ceramic carrier and make; Again ceramic monolith is wrapped with the vibration damping sealing gasket, be encapsulated in and make complete catalytic converter in the Stainless Steel Shell.The meaning of " three-element catalytic conversion " is meant the catalyzer that is coated on the ceramic monolith, energy simultaneous oxidation carbon monoxide (CO) and hydrocarbon (HC), reduction of nitrogen oxide (NO X), after above-mentioned three kinds of harmful gases touch catalyzer, form harmless effulent by catalyzed conversion: water vapour (H 2O), carbon dioxide (CO 2) and nitrogen (N 2).
The utility model uses the catalyst of two different holes density, wherein: because higher relatively in air inlet front end delivery temperature, between two metal electron sieves, add a catalyst, can effectively utilize the transformation efficiency of delivery temperature raising to harmful gas, ceramic monolith separates two metal electron sieves simultaneously, plays insulation and reinforces the effect that metal electron is sieved stress-bearing capability.The air inlet front end contains a large amount of carbon soot particles also not to be had processed; should adopt hole density to be the catalyst that is clipped between the metal electron sieve: the ceramic monolith of 250-300 hole/square inch; can be when effectively handling harmful exhaust; avoid because the too small formation carbon distribution of hole density, stop up ceramic honeycomb carrier and shorten working life of product.The catalyst that is contained in the rear end adopts hole density to be: the ceramic monolith of 400 hole/square inches, carbon soot particles was processed finishes for the overwhelming majority when waste gas arrived this catalyst, adopt the ceramic monolith of 400 hole/square inches can increase the specific surface area of catalyst, improve transformation efficiency.Experiment shows, as long as strict with the original emission status coupling of diesel engine the utility model, can make carbon soot particles discharging minimizing 80%-90%, and the transformation efficiency of corresponding other harmful gases of raising.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
