The utility model discloses a kind of automobile exhaust pipe, comprise exhaust pipe and be positioned at ternary catalyzing unit, silencing apparatus and the relief opening in exhaust pipe successively, the internal pipeline of described silencing apparatus is provided with hole, in described silencing apparatus, be also provided with double-deck mesh; Also photocatalyst purifier is provided with between described ternary catalyzing unit and silencing apparatus, described photocatalyst purifier comprises ultraviolet lamp and by the disk made with catalyst activity thing, be provided with rotating shaft in the center of above-mentioned disk, the two ends of rotating shaft are connected to connecting rod and connect ultraviolet lamp by connecting rod.Its technique effect is by increasing photocatalyst purifier thus the purification ratio of raising vehicle exhaust; Ultraviolet lamp is set around purification disc rotary, photo catalysis catalysis efficiency is improved, improves the purification ratio of tail gas further; Double-deck mesh is set in silencing apparatus in addition, then the noise that when reducing automobilism, tail gas produces.
Description
Technical field
The utility model relates to a kind of automobile exhaust pipe.
Background technique
Automobile exhaust gas includes thousands of kinds of chemical substances, can be divided into two large classes: particulate matter, as the heavy metal etc. of carbon black, tar; Gas, as carbon monoxide, hydrocarbon, aldehydes etc.And discharge of automobile exhaust fumes is mainly between 0.3 meter to 2 meters, be just in time the respiration range of human body, therefore can serious harm to the health of people.Vehicle exhaust can cause the numerous disease of being grown up, and as caused brain glandular secretion to get muddled and oxidative damage, thus affects IQ; Benzene class material strong carcinogen especially in tail gas, can lung cancer caused, thyroid cancer etc.Owing to containing the higher Benzene and Toluene of concentration in gasoline, if these materials burn insufficient, carcinogenic substance will be produced.Also can produce nitrogen oxide during gasoline combustion in addition, it has detrimental effect to the respiratory system of people.
Purified treatment at present for tail gas mainly adopts ternary cleaner, it mainly utilizes the noble metals such as platinum, rhodium, palladium to become water and carbon dioxide as catalyzer thus by the carbon monoxide in vehicle exhaust, hydrocarbon, decompose nitrogen oxides is become nitrogen and oxygen simultaneously, but the position of laying due to ternary catalyzing unit is away from relief opening, the light-off time of catalyst converter is longer, because cannot be cleaned out by the hazardous substance in vehicle exhaust well.Often only process its internal pipeline in silencing apparatus in addition in existing outlet pipe, as punching or change the arrangement of pipeline on pipeline, but such silencing apparatus is still short of for the performance reducing the noise produced because of vehicle exhaust.
Model utility content
The purpose of this utility model provides a kind of purifying vehicle exhaust rate that can improve can compared with the automobile exhaust pipe of low exhaust gas noise to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, automobile exhaust pipe designed by the utility model, comprise exhaust pipe and be positioned at ternary catalyzing unit, silencing apparatus and the relief opening in exhaust pipe successively, the internal pipeline of described silencing apparatus is provided with hole, in described silencing apparatus, be also provided with double-deck mesh; Also photocatalyst purifier is provided with between described ternary catalyzing unit and silencing apparatus, described photocatalyst purifier comprises ultraviolet lamp and by the disk made with catalyst activity thing, be provided with rotating shaft in the center of above-mentioned disk, the two ends of rotating shaft are connected to connecting rod and connect ultraviolet lamp by connecting rod.
The setting of double-deck mesh in above-mentioned silencing apparatus, can make tail gas reach airflow diversion by multichannel, is more mutually impacted by each point of air-flow, and air-flow velocity is slowed down, and through repeatedly such process, reaches waste gas and is slowly flowed out by relief opening, to reach noise elimination object.
The above-mentioned ultraviolet lamp that arranges, around purification disc rotary, increases the surface of contact of ultraviolet lamp and disk, photo catalysis catalysis efficiency is improved, improve the purification ratio of tail gas further.
In order to increase the surface of contact of vehicle exhaust and catalyst activity thing, on described disk, the arrangement of catalyst activity thing is cellular.
In order to better reduce the noise because tail gas during automobilism produces, the bore of the relative aperture exhaust pipe of described relief opening is large.
The automobile exhaust pipe that the utility model obtains, its technique effect is by increasing photocatalyst purifier thus the purification ratio of raising vehicle exhaust; Ultraviolet lamp is set around purification disc rotary, photo catalysis catalysis efficiency is improved, improves the purification ratio of tail gas further; Double-deck mesh is set in silencing apparatus in addition, then the noise that when reducing automobilism, tail gas produces.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment:
As shown in Figure 1 and Figure 2, the automobile exhaust pipe that the present embodiment provides, comprise exhaust pipe 1 and be positioned at ternary catalyzing unit 2, silencing apparatus 3 and the relief opening 4 in exhaust pipe 1 successively, the internal pipeline of described silencing apparatus 3 is provided with hole 31, in described silencing apparatus 3, be also provided with double-deck mesh 32; Photocatalyst purifier 5 is also provided with between described ternary catalyzing unit 2 and silencing apparatus 3, as shown in Figure 3, Figure 4, described photocatalyst purifier 5 comprises ultraviolet lamp 6 and by the disk 7 made with catalyst activity thing, be provided with rotating shaft 8 in the center of above-mentioned disk 7, the two ends of rotating shaft 8 are connected to connecting rod 9 and connect ultraviolet lamp 6 by connecting rod 9.In order to increase the surface of contact of vehicle exhaust and catalyst activity thing, on described disk 7, the arrangement of catalyst activity thing is cellular.In order to better reduce the noise because tail gas during automobilism produces, the bore of the relative aperture exhaust pipe 1 of described relief opening 4 is large.
In concrete using process, under the drive of motor, ultraviolet lamp 6 rotates around by the disk 7 made with catalyst activity thing, forms photocatalyst purifier 5.Vehicle exhaust escapes and enter in exhaust pipe 1 from motor, and after the process of ternary catalyzing unit 2, carbon monoxide, hydrocarbon and nitrate compound in most of tail gas are processed; Then tail gas enters in photocatalyst purifier 5, is also disposed by remaining waste gas; Then by silencing apparatus 3, automobile is first rushed out from hole 31, and the multichannel then through double-deck mesh 32 is shunted, and air-flow velocity is slowed down thus reduces noise; Last tail gas is discharged from relief opening 4.
