Abstract
The utility model discloses a diesel engine motor vehicle tail gas catalytic purification silencer, including air intake hood with go out the gas hood, air intake hood is including being used for sleeve pipe and the gas flow distribution chamber is connected with the engine, it is symmetrical with air intake hood to go out the gas hood structure, is connected with two at least corrugated tubes between air intake hood and the play gas hood, has catalytic converter in the corrugated tube. The utility model discloses compact structure, the spare part type is few, and the regeneration of manufacturing, equipment, maintenance, change and the combustor of spare part is torn open and is traded all very portably, because engine exhaust tail gas is disperseed to carry out catalytic purification and noise elimination into more than one channel, has improved purifying effect and noise suppression effect.
Description
Technical field
The utility model relates to motor vehicle fittings, specifically diesel car diesel engine road vehicle tail gas catalytic purification silencing apparatus.
Background technique
In disclosed document, catalytic purification is arranged on silencing apparatus by people, make silencing apparatus become arrangement for catalytic purification simultaneously, such as, CN104564252A discloses a kind of exhaust gas from diesel vehicle after-treatment device, comprise sleeve, suction tude, inner end cap is provided with in sleeve, in sleeve, integral type is provided with purification plant, silencer, purification plant comprises carrier catalysis device, grain catcher, silencer comprises hush tube, noise reduction inner end cap, hush tube is connected with cylindrical shell by noise reduction inner end cap and dividing plate, the end of hush tube is hush tube of giving vent to anger, hush tube of giving vent to anger stretches out outside sleeve and is connected with outlet side flange, in described suction tude, socket is provided with tinfoil paper insulating pipe with corrugation insulating layer or stainless steel double thermal insulation pipe.CN201284683Y discloses a kind of purification silencer for exhaust gas of diesel engine, and comprise the closed chamber formed by housing, front cover and rear end cover, the front end of this chamber is provided with suction tude, and rear end is provided with outlet pipe; At described housing built with device for catalytic treatment, device for catalytic treatment is made up of coaxial 2 to 5 catalytic filters, is provided with isolating ring between two adjacent catalytic filters.CN203769892U discloses a kind of catalytic silencer for diesel, it comprises housing, suction tude, outlet pipe and carrier, enclosure interior is disposed with ante-chamber, lumen and back cavity from left to right, and carrier is arranged in lumen, and the front end of outlet pipe is fixedly connected with absorbing plate.Because arrangement for catalytic purification cross-sectional sizes is restricted, can not be suitable for larger air displacement, for high power engine, be amplified by these catalytic mufflers above-mentioned, will reduce soundproof effect, the dismounting of device for catalytic treatment regeneration process is very inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of catalytic purifying muffler being applicable to high power engine.
Exhaust gas from diesel vehicle catalytic purifying muffler of the present utility model comprises airscoop shroud and air leaving cover, airscoop shroud comprises sleeve pipe for being connected with motor and gas flow distribution cavity, air leaving cover structure and airscoop shroud symmetry, be connected with at least two corrugated tubes between airscoop shroud and air leaving cover, in corrugated tube, have catalytic cleaner.
Preferably, homogenizing plate is had in described gas flow distribution cavity.
Above-mentioned corrugated tube can comprise waveform segment and direct tube section, and catalytic cleaner is arranged in direct tube section.
Have circular sleeve between described airscoop shroud and air leaving cover, corrugated tube is accommodated in circular sleeve.
The utility model compact structure, component type is few, the regeneration of the manufacture of component, assembling, maintenance, replacing and burner changes all very easy, tail gas due to motor discharge is dispersed into multiple passage and carries out catalytic purification and noise elimination, improve purifying effect and soundproof effect, arrangement for catalytic purification can use the purifying processing devices such as SCR, DOC, DPF, CDPF, the reprocessing of particularly suitable high power engine tail gas.

Fig. 4 is G-G sectional view.
Embodiment
As shown in the figure, catalytic purifying muffler of the present utility model comprises airscoop shroud 1 and air leaving cover 2, airscoop shroud 1 comprises the sleeve pipe 11 for being connected with motor and distributes the gas flow distribution cavity 12 of air-flow, there is adpting flange sleeve pipe 11 front end or leaves socket gap, can with engine exhaust port simple connection, sleeve pipe 11 rear end extends in distribution chamber 12, and form numerous through hole 14 so that tail gas overflows from through hole 14 at tube wall, homogenizing plate 13 is had in distribution chamber 12, homogenizing plate 13 is porous slab, there is the interface 15 of some corrugated tubes 3 at homogenizing plate 13 rear, by the through hole 14 of sleeve pipe 11 tube wall and the shunting of homogenizing plate 13, tail gas can uniform divided flows in corrugated tube 3, reduce flow velocity, be conducive to catalytic purification and noise elimination.
The structure of air leaving cover 2 and airscoop shroud 1 symmetry.
Corrugated tube interface 15 between airscoop shroud 1 and air leaving cover 2 is connected with some corrugated tubes 3, each corrugated tube 3 is fastened on corrugated tube interface 15 by locking clip 34,35, each corrugated tube 3 comprises waveform segment 31 and direct tube section 32, catalytic cleaner 33 is arranged in direct tube section 32, the Main Function of waveform segment 31 is eliminated the noise, catalytic cleaner preferably uses DPF carbon soot particles catcher, CDPF carbon soot particles catalytic burner, carries out catalytic purification to soot particulate, hydrocarbon, carbon monoxide, nitrogen oxide in tail gas.Because waveform segment 31 has slight evagination, the waveform segment 31 of adjacent corrugated tube 3 staggers mutually, and structure can be made compacter.
Have circular sleeve 4 between airscoop shroud 1 and air leaving cover 2, airscoop shroud 1, air leaving cover 2 and corrugated tube 3 are accommodated in circular sleeve 4, and sleeve 4 becomes sound insulation and heat-proof device.
