Description
The utility model relates to a kind of new automobile tail-gas purifying silencer, belongs to the purifying vehicle exhaust silencer.
At present, existing purifying vehicle exhaust silencing apparatus of China or title purifying vehicle exhaust silencer, because its structural reason also exists many defectives, as: 1. CO, cleaning harmful gas such as CH compound and NOx are unclean, most decontamination indexs that all can not reach State Bureau of Environmental Protection's regulation; Though the decontamination index that can reach national regulation that 2. has, working life is extremely low, can only use several thousand kilometers, and super only 10,000 kilometers ranges of driving will be changed, and leave the index that national regulation surpasses 50,000 kilometers ranges of driving, and will be too wide in the gap; 3. for the purifying muffler of band secondary air compensating, A sound level noise＞91 decibels, from State Bureau of Environmental Protection regulation≤85 decibels of indexs also differ greatly etc., existing in a word purifying vehicle exhaust silencing apparatus awaits further to improve.
The purpose of this utility model just is to design a kind of simple in structure, is filled with the sound absorption material in double Shell, and the purifying vehicle exhaust silencing apparatus of silencing apparatus is installed in housing, to overcome the deficiencies in the prior art.
The purpose of this utility model is achieved in that it is mainly by suction tude (1), housing (3), ejector (4), sound absorption and insulation material (5), silencing apparatus (6), catalyst carrier parts such as (7) are formed, the end and the suction tude (1) that it is characterized in that housing (3) and inner housing (2) are affixed, the other end of housing (3) and inner housing (2) and steam outlet pipe (11) are affixed, between housing (3) and the inner housing (2) sound absorption and insulation material (5) is installed, the front end of housing (3) is provided with tonifying Qi hole (15), be connected with ejector (4) and baffle plate (14) in the front end of inner housing (2), the middle part of inner housing (2) is connected with silencing apparatus (6), the rear portion of inner housing (2) dashes and is filled with catalyst carrier (7), and the rear portion of inner housing (2) also is provided with vibration damper (8) and lining (9).
Its feature is that also described ejector (4) is to be welded with many induction tunnels (16) to form on baffle plate (14), leaves slit (20) between baffle plate (14) and induction tunnel (16).
Its feature is that also described silencing apparatus (6) is to be welded with suction tude (17) and steam outlet pipe (18) on dividing plate (13), and is provided with aperture (19) and forms.
Its feature is that also the termination of described suction tude (1) and steam outlet pipe (11) is provided with damping hole (12).
Its feature is that also described housing (3) two ends are the biconial of circular cone or elliptic cone, and the centre is cylindrical or elliptical cylinder-shape.
The utility model is compared with prior art: it is reasonable in design, and is simple in structure, is filled with the sound absorption material and silencing apparatus is installed in double Shell, is applicable to the tail gas clean-up and the noise elimination of various vehicles, its decontamination index height, and it is effective to eliminate the noise, long service life.
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing 1 is the whole broken section structural representation of the utility model.
Accompanying drawing 2 is for being welded with the structural representation behind the induction tunnel (16) on the utility model parts baffle plate (14).
Accompanying drawing 3 is for being welded with the structural representation behind suction tude (17) and the steam outlet pipe (18) on the dividing plate (13).
Among the figure: 1, suction tude, 2, inner housing, 3, housing, 4, ejector, 5, sound absorption and insulation material, 6, silencing apparatus, 7, catalyst carrier, 8, vibration damper, 9, lining, 10, flow-collecting chamber, 11, steam outlet pipe, 12, damping hole, 13, dividing plate, 14, baffle plate, 15, tonifying Qi hole, 16, induction tunnel, 17, suction tude, 18, steam outlet pipe, 19, aperture, 20, the slit.
As can be seen from the figure, it mainly is made up of the utility model suction tude (1), housing (3), ejector (4), sound absorption and insulation material (5), silencing apparatus (6), catalyst carrier parts such as (7), described housing (3) two ends are the biconial of circular cone or elliptic cone, and the centre is cylindrical or elliptical cylinder-shape; Described ejector (4) is to be welded with many induction tunnels (16) to form on baffle plate (14), and the induction tunnel of present embodiment (16) has 7, leaves slit (20) between baffle plate (14) and induction tunnel (16); Described silencing apparatus (6) is to be welded with suction tude (17) and steam outlet pipe (18) on dividing plate (13), and is provided with aperture (19) and forms; The termination of described suction tude (1) and steam outlet pipe (11) is provided with damping hole (12); Its overall structure is affixed at an end of housing (3) and inner housing (2) and suction tude (1), the other end of housing (3) and inner housing (2) and steam outlet pipe (11) are affixed, between housing (3) and the inner housing (2) sound absorption and insulation material (5) is installed, the front end of housing (3) is provided with tonifying Qi hole (15), be connected with ejector (4) and baffle plate (14) in the front end of inner housing (2), the middle part of inner housing (2) is connected with silencing apparatus (6), the rear portion of inner housing (2) dashes and is filled with catalyst carrier (7), and the rear portion of inner housing (2) also is provided with vibration damper (8) and lining (9).
