Abstract
A silencer for purifying gas exhaust of motor vehicle consists of shell, air inlet tube, air outlet tube, front sealing cover, back sealing cover, internal cylinder, swirler, catalytic heat conductive device and front louver used as air suction mouth. It can burn harmful gas exhausted from motor vehicle completely in course of gas exhausting so as to decrease air pollution.
Description
Technical field
The present invention relates to the automobile exhausting device, particularly a kind of exhaust purging muffler of internal combustion engine of motor vehicle.
Background technique
Existing motor-vehicle tail-gas Exhaust gas purifying device has three-way catalyst ceramic honeycomb body, diesel engine chemistry fiber filter catcher etc.The delivery temperature of ceramic honeycomb body purification plant just plays conversion reaction to harmful gas when being higher than 700 ℃, but when " honeycomb " stopped up by particulate matter, then to no effect.The chemical fibre filter traps is to not reduction effect of harmful gas.Above-mentioned two kinds of apparatus structure complexity involve great expense, and trouble is installed, and internal-combustion engine back pressure height, and working life is shorter.
Summary of the invention
Task of the present invention provides a kind of improved purifying vehicle exhaust gas silencing apparatus, it has solved, and above-mentioned purification plant purifying effect is poor, complex structure, involve great expense, problem that working life is short.
Technological scheme of the present invention is as follows:
A kind of purifying vehicle exhaust gas silencing apparatus, it comprises housing, suction tude in the arrangement of housing one end, steam outlet pipe in the arrangement of the housing the other end, preceding capping in the housing one end installing that is positioned at suction tude, and at the rear seal-cover of the housing the other end installing that is positioned at steam outlet pipe, it also is included in a wherein end and the suction tude sealing and fixing that enclosure interior is settled, the other end is eddy flow air outlet and the inner core that is connected with steam outlet pipe, the inner core positioned inside and by the fixing cyclone separator of support, the catalysis heat-transfer device of between housing and inner core, installing, and the preceding venetian blind air suction inlet that in preceding capping, is provided with.
Use purifying vehicle exhaust gas silencing apparatus of the present invention, can make the internal combustion engine of motor vehicle harmful gas in discharge process, reach perfect combustion, farthest reduce the pollution of internal combustion engine of motor vehicle toxic emission environment.
Modern design of the present invention, rational in infrastructure, easy to install, easy and simple to handle, be applicable to the internal combustion engine of motor vehicle of various models.
Description of drawings
Fig. 1 is the structural representation of a kind of purifying vehicle exhaust gas silencing apparatus of the present invention.
Fig. 2 is that A among Fig. 1 is to sectional drawing.
Fig. 3 is the B-B view among Fig. 1.
Embodiment
Referring to Fig. 1 to Fig. 3, a kind of purifying vehicle exhaust gas silencing apparatus of the present invention is equipped with housing 1, settles suction tude 2 at housing 1 one ends, settles steam outlet pipe 3 at housing 1 the other end, and suction tude 2 is connected with the internal combustion engine of motor vehicle discharge pipe.
Capping 4 before the housing 1 one ends installing that is positioned at suction tude 2, housing 1 the other end installing rear seal-cover 5 that is being positioned at steam outlet pipe 3.Venetian blind air suction inlet before being provided with in preceding capping 4 is provided with back venetian blind secondary air suction port on rear seal-cover 5.Can install air inlet control baffle plate 12 at preceding venetian blind air suction inlet place and venetian blind secondary air suction port place, back.
In housing 1 inside inner core 6 is set, inner core 6 one ends and suction tude 2 sealing and fixing, inner core 6 the other ends are provided with eddy flow air outlet 7 and are connected with steam outlet pipe 3.The inner of eddy flow air outlet 7 be equipped with the back in capping 8, the outer end of eddy flow air outlet 7 is connected with steam outlet pipe 3, and a taper flow-guiding mouth 9 is arranged in this joint, just steam outlet pipe 3 with 7 joints, inner core eddy flow air outlet are taper flow-guiding mouths 9.
In inner core 6 inside cyclone separator 10 is housed, cyclone separator 10 is fixed in inner core 6 edges by support 11, is provided with eddy flow gas aisle space at cyclone separator 10 peripheries.It is conical that cyclone separator 10 is, and has spiral helicine eddy flow track structure (as shown in Figure 2).Capping 14 in before the outer end of cyclone separator 10 is to be equipped with between inner core 6 edges and the suction tude 2.
The catalysis heat-transfer device is installed between housing 1 and inner core 6.As shown in Figure 3, the catalysis heat-transfer device can be a kind of catalysis heat conduction circle 13 that is concavo-convex corrugation ring-type, is fixedly mounted on inner core 6 outer rings.This catalysis heat conduction circle 13 is to be made by aluminium rare earth alloys and cadmium bronze material.
When the present invention works, enter suction tude by internal combustion engine of motor vehicle discharged waste gas, enter inner core through cyclone separator, produce negative pressure between housing and the inner core, this moment, fresh air sucked from the preceding venetian blind air suction inlet that is positioned in the preceding capping, be directed to the taper flow-guiding mouth that is connected with the eddy flow air outlet through catalysis heat conduction circle, fresh air converges mutually with eddy flow tail gas, play redox reaction, also have air to suck simultaneously from the back venetian blind secondary air suction port that is positioned on the rear seal-cover, mixed gas and airborne oxygen are reacted once more, discharge from steam outlet pipe until clean gas.
