Abstract
The utility model discloses a waste gas purifying silencer for a lightweight car, which comprises a cylindrical silencing pipe, wherein sealing covers are arranged at two ends of the silencing pipe; three silencing chambers are arranged in the silencing pipe; a gas inlet pipe and a gas outlet pipe are arranged at the two ends of the silencing pipe; the gas inlet pipe and the gas outlet pipe pass through the three silencing chambers; and opening parts of the gas inlet pipe and the gas outlet pipe extend out of the sealing covers. The waste gas purifying silencer for the lightweight car has the beneficial effects that a purifying silencer in different size or a plurality of purifying silencers in same size in parallel connection can be selected according to engines with different output volumes; water-filtering purifying effects are basically the same when a car is driven under the condition of uphill, downhill, acceleration, deceleration or flat road, the service life is long, the running cost is low and the purifying effect is excellent; energy resource is saved, environmental pollution is reduced, noise reduction is large and power loss is small; and the waste gas purifying silencer for the lightweight car meets the national demands on limit values of emission and noise.
Description
Technical field
The utility model relates to a kind of silencing apparatus, specifically relates to a kind of light-duty vehicle and uses exhaust gas purification muffler, belongs to the auto parts machinery field.
Background technique
At present, along with improving constantly of living standard, the quantity of Motor Vehicle is more and more, and motor vehicle exhaust gases is also more and more serious to the pollution of atmosphere, especially in big and medium-sized cities motor-vehicle tail-gas oneself is discharged to first to the pollution of urban atmosphere.At present; Existing exhaust silencer mainly adopts the resistance exhaust silencer structure of pipeline section expansion and cross-sectional constriction, utilizes sound wave in the variation of abrupt change of cross-section place owing to acoustic reactance, and some sound wave reflects back to sound source; And the not outlet through silencing apparatus; Thereby reach the purpose of noise elimination, but this silencing apparatus is when using on minicar, the shortcoming of indivedual strong noise frequency contents can not be effectively eliminated in existence.
The model utility content
To the deficiency that existing technology exists, the utility model technical problem to be solved is, provides a kind of light-duty vehicle use exhaust gas purification muffler, and environmental protection, noise elimination are effective, good purification, and also simple in structure, easy to use, reduced cost of production.
For solving the problems of the technologies described above, the technological scheme that the utility model is taked is that a kind of light-duty vehicle is used exhaust gas purification muffler; Comprise columniform hush pipe; The two ends of its hush pipe are provided with sealing cover, and the hush pipe set inside has three anechoic chambers, and the two ends of hush pipe are provided with suction tude and steam outlet pipe; Suction tude and steam outlet pipe pass three anechoic chambers, and oral area stretches out sealing cover; Said suction tude connects waste gas cleaning plant, and waste gas cleaning plant comprises that purifies a chamber, purifies the chamber two ends and is provided with exhaust gas entrance and waste gas outlet, and waste gas outlet connects suction tude; The middle part of said purification chamber is provided with dividing plate, and exhaust gas entrance connects side space under the dividing plate through pipeline, and dividing plate is provided with some equally distributed gas ports.
Optimize, above-mentioned light-duty vehicle is used exhaust gas purification muffler, and its suction tude is provided with some pores in inner position, three anechoic chambers.
Optimize, above-mentioned light-duty vehicle is used exhaust gas purification muffler, and its steam outlet pipe is provided with some pores in inner position, three anechoic chambers.
Optimize, above-mentioned light-duty vehicle is used exhaust gas purification muffler, and its steam outlet pipe oral area is provided with wire netting.
The beneficial effect of the utility model is: can select the purifying muffler of different sizes according to the motor of different displacements for use, or select for use the purifying muffler parallel connection of a plurality of identical sizes to use; At automobile upward slope, descending, acceleration, deceleration or flat pavement running, water filter purifying effect is the same basically, long service life, low, the good purification of operating cost; Both energy saving can reduce environmental pollution again, and sound deadening capacity is big, and power loss ratio is little, satisfied the limit value requirement of country about discharging and noise.
Description of drawings
Below in conjunction with accompanying drawing and embodiment to the utility model further explain:
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; The utility model is that a kind of light-duty vehicle is used exhaust gas purification muffler, comprises columniform hush pipe 1, and the two ends of its hush pipe 1 are provided with sealing cover 2; Hush pipe 1 set inside has three anechoic chambers 11; The two ends of hush pipe 1 are provided with suction tude 12 and steam outlet pipe 13, and air inlet 12 pipes and steam outlet pipe 13 pass three anechoic chambers 11, and oral area stretches out sealing cover 2; Said suction tude 12 connects waste gas cleaning plant 3, and waste gas cleaning plant 3 comprises that purifies a chamber 31, purifies chamber 31 two ends and is provided with exhaust gas entrance 32 and waste gas outlet 33, and waste gas outlet 33 connects suction tude 12; The middle part of said purification chamber 31 is provided with dividing plate 34, and exhaust gas entrance 32 connects 34 times side spaces of dividing plate through pipeline, and dividing plate 34 is provided with some equally distributed gas ports 35.11 inner positions are provided with some pores 14 to suction tude 12 three anechoic chambers.11 inner positions are provided with some pores 14 to steam outlet pipe 13 three anechoic chambers.Steam outlet pipe 13 oral areas are provided with wire netting 15.The beneficial effect of the utility model is: can select the purifying muffler of different sizes according to the motor of different displacements for use, or select for use the purifying muffler parallel connection of a plurality of identical sizes to use; At automobile upward slope, descending, acceleration, deceleration or flat pavement running, water filter purifying effect is the same basically, long service life, low, the good purification of operating cost; Both energy saving can reduce environmental pollution again, and sound deadening capacity is big, and power loss ratio is little, satisfied the limit value requirement of country about discharging and noise.
Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited to above-mentioned giving an example; Those skilled in the art; In the essential scope of the utility model, the variation of making, remodeling, interpolation or replacement all should belong to the protection domain of the utility model.
