Abstract
The utility model relates to a tail gas purifier for paramagnetic coupling automobiles, which is composed of a metallic cylindric outer sleeve of which the front and the back are provided with an air inlet and an exhaust outlet, a built-in catalytic purifying filtering core and a magnetic field which is arranged in a rounding mode, wherein the magnetic field comprises an electromagnet which is wound outside a housing or an electromagnet which is wound inside the housing. The combination of paramagnetic coupling and catalytic purification is used for the technical field of tail gas purification for automobiles and can also be used for other fields, especially for processing gas-phase systems containing Nox such as industrial flue gas.
Description
The utility model relates to a kind of automobile exhaust purifier, belongs to the exhaust gas treatment device technical field to fuel engine oxious component catalyzed conversion.
The task of top priority of administering auto-pollution is the cleaning of off-gas discharging, the hot subject of tail gas clean-up mainly is to purify NOx, I at first to file (application number: 00242877.6) disclose employing metallic nickel or nickel alloy net, cooperated the technological scheme of magnetization purifying automobile tail gas simultaneously as catalyzer and catalyzed conversion carrier clean unit.
The purpose of this utility model is to provide a kind of automobile exhaust purifier of paramagnetic coupled structure, and the mode of taking outside the purifier shell or adding certain energy electromagnetic field in the shell makes the relative enrichment of NOx and improves reactivity, thus the strengthened purification effect.
The technical solution of the utility model is achieved in that this paramagnetic coupling automobile exhaust purifier, the metal tub overcoat of suction port, relief opening and built-in catalytic purification filter core are set, are formed around the magnetic field that is provided with by front and back, described magnetic field comprises the electromagnet that the electromagnet that is looped around housing exterior or ring place enclosure.
Also comprise the permanent magnet that is looped around housing exterior around the magnetic field that is provided with described in the described paramagnetic coupling automobile exhaust purifier.
Between the magnet of described paramagnetic coupling automobile exhaust purifier and the filter core insulation layer is set.
The housing of the external magnet of described paramagnetic coupling automobile exhaust purifier is provided with radiation hole.
Between the electromagnet of described paramagnetic coupling automobile exhaust purifier and the filter core isolation layer is set.
The shell of described paramagnetic coupling automobile exhaust purifier is provided with the secondary air intake mouth.
Described paramagnetic coupling automobile exhaust purifier insulating terminal is set.
The metal shell inwall of described paramagnetic coupling automobile exhaust purifier is provided with buffer layer.
The major advantage of the paramagnetic coupling and intensifying purified treatment scheme that the utility model adopts is:
Magnetization is handled and can be made contaminant molecule be in the magnetic field of high strength and highdensity horizontal magnetic force line cutting, and constantly some paramagnetic gas such as O are clashed in displacement
2, NO, NO
2Produce " Skin effect ", for the acceleration of follow-up catalytic conversion reaction with condition thoroughly is provided.
Describe technology contents of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is the automobile exhaust purifier sectional view of external magnetic field
Fig. 2 is among the automobile exhaust purifier sectional view figure in built-in magnetic field: 1, suction port 2, secondary air inlet mouth 3, buffer layer 4, magnet 5, radiation hole 6, thermal insulation layer 7, nickel screen filter core 8, metal shell 9, relief opening 10, isolation layer 11, coil 12, iron core 13, thermal insulation layer 14, insulating terminal
Working principle of the present utility model is: motor car engine is discharged contains CO, HC and NO
x, the high-temp waste gas of pollutant enters the non-uniform electromagnetic field and the layering of catalytic reactor, at the low magnetic flux density region, and relatively enrichment and the NO that activates because of the paramagnetic coupling
2Catalytic reduction reaction takes place and is converted into N in the catalyst selectivity adsorption activation that fully mixes and be placed in this district with reducing agent CO, HC
2, CO
2And H
2O leaves this reactor.Combined in the active O in high magnetic flux density district by relative rich
2Advancing the follow-up conventional oxidation reactor of people is CO and H with remaining CO in the waste gas and HC catalytic oxidation
2O.
NO and O
2The electron pair pole span of molecule is made reactivity higher by the magnetic force coupling, and in conventional delivery temperature scope, the NO of activation is by the higher activation O of relative concentration
2Be oxidized to NO rapidly
2And enter NO
2Enrichment region and be innocuous gas by catalytic reduction; Other of NOx may existence form such as N
2O, N
2O
3, N
2O
4Deng or because of the tool diamagnetism, or because of being decomposed into NO rapidly
2Etc. reason, all be constrained to the catalytic reduction district and by CO and HC reduction, harmless gas phase component that reaction generates and the component that has neither part nor lot in reaction are deflated power and push away the reduction catalysts layer continuously.
Found out that by accompanying drawing the utility model has provided three kinds of mode of executions of two kinds of situations, promptly built-in setting with external magnetic field, external magnetic field is divided into permanent magnet 4 or electromagnet 11,12 again; The shaped design of magnet or coil is a symmetry watt shape, and the power supply of calutron is car accumulator 12V, transfers in the 1000V through high-frequency electric field generator, pulse oscillator, pressure governor, and device enters running state after automobile dynamic system starts.For the demagnetizing action that prevents that high temperature from causing, outside magnet, be provided with thermal insulation layer 6,13 and radiation hole 5, catalysis filter core 7 adopts nickel screen or nickel alloy net to apply the active catalyst coating as carrier or cordierite honeycomb ceramic again as carrier.
The paramagnetic coupling is united the technology that is used for purifying vehicle exhaust with catalytic purification, also can be used for the processing that other field especially contains NOx gassy system such as industrial flue gas.
