Abstract
The utility model relates to an exhaust pipe, in particular to the exhaust pipe capable of accelerating the exhausting of waste gas. The exhaust pipe comprises a shell body and an exhaust pipeline. An arc-shaped device capable of accelerating the exhausting of the waste gas is arranged at the tail end of the air exhaust pipeline and fills the whole pipeline. Air permeable holes are formed in the air inlet face and the air outlet face of the arc-shaped device capable of accelerating the exhausting of the waste gas, and the area of each air permeable hole which is formed in the air inlet face is larger than the area of the air permeable hole which is formed in the air outlet face. Air permeability catalysts which are used for purifying tail gas are arranged in the arc-shaped device capable of accelerating the exhausting of the waste gas. Due to the adoption of the structure, the waste gas can be farther exhausted, and the exhausted waste gas can reach an emission standard regulated by a country.
Description
Technical field
The utility model relates to a kind of outlet pipe, particularly a kind of outlet pipe that accelerates the waste gas discharge.
Background technique
Along with expanding economy, living standards of the people constantly improve, and people are also increasing to the demand of automobile.In order to satisfy the demand to automobile, keep again sustainable development on the one hand on the one hand, so just need to the tail gas of motor vehicle emission be purified, allow the waste gas of discharging can reach certain standard.
Usual seen outlet pipe does not accelerate the device of exhaust emissions, so the exhaust gas velocity that gives off is slower, can not discharge far.When running into reverse wind, be unfavorable for the discharging of waste gas simultaneously, the work of automobile will be not smooth like this.
Summary of the invention
The utility model technical issues that need to address provide a kind of waste gas that can accelerate and discharge also well purifying waste gas pollutants, make it reach the outlet pipe of emission standard.
For solving the problems of the technologies described above, outlet pipe of the present utility model comprises housing and exhaust duct, has arc to accelerate the device that waste gas discharges at the tail end of exhaust duct and is full of whole exhaust duct; On the air inlet face of the device that arc acceleration waste gas is discharged and the face of giving vent to anger air hole is arranged, and the air hole area of air inlet face is greater than the area of the face air hole of giving vent to anger; The device that arc acceleration waste gas is discharged contains the gas permeability catalyzer of cleaning of off-gas.
The device that this arc accelerates the waste gas discharge can be a kind of cystidium, and described cystidium is that two corresponding arc plates that are drilled with manhole are formed by connecting, and catalyzer is placed in the cystidium.Circular air hole equal and opposite in direction on cystidium air inlet face and the face of giving vent to anger, the air hole quantity of air inlet face is greater than the face air hole quantity of giving vent to anger.
The device that this arc accelerates the waste gas discharge can also be an arc plate, and the above has the ventilative through hole of hole shape, and described tail-gas catalyst is bonded on the ventilative through hole.The sectional shape of the ventilative through hole of described hole shape is trapezoidal, and whole through hole becomes round table-like.
After adopting such structure, because the air hole area of air inlet face is greater than the area of the face air hole of giving vent to anger, thereby so that the flow velocity of outlet pipe end waste gas increases, can make farther that waste gas discharges.Again because arc accelerates the gas permeability catalyzer that the device of waste gas discharge contains cleaning of off-gas, so the waste gas of discharging can reach the emission standard of national regulation.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model outlet pipe.
Fig. 2 is the air inlet face schematic representation of the utility model outlet pipe the first mode of execution cystidium.
Fig. 3 is the face of the giving vent to anger schematic representation of the utility model outlet pipe the first mode of execution cystidium.
Fig. 4 is the structural representation of the utility model outlet pipe the second mode of execution arc plate.
Among the figure: 1 is housing, and 2 is exhaust duct, 3 cystidiums, and 4 is catalyzer, and 5 is the air inlet face air hole, and 6 are the face air hole of giving vent to anger, and 7 is arc plate
Embodiment
Outlet pipe as shown in Figure 1 comprises housing 1 and exhaust duct 2, the tail end of exhaust duct 2 has cystidium 3, bore a plurality of air holes at two blocks of plectanes, circular plate bending is become certain radian, two plectanes are connected, so just form cystidium 3 with exhaust duct 2, catalyzer 4 is placed in the cystidium 3, like this can well cleaning of off-gas, make the tail gas that gives off reach emission standard.
Fig. 2 has provided the distribution map of the air inlet face air hole 5 of cystidium 3, Fig. 3 has provided the distribution map of the face of the giving vent to anger air hole 6 of cystidium 3, the equal and opposite in direction of air inlet face air hole 5 and the face air hole 6 of giving vent to anger, but the quantity of air inlet face air hole 5 is more than the face air hole 6 of giving vent to anger, so the gross area of air inlet face air hole 5 is greater than the face air hole 6 of giving vent to anger, the speed of waste gas discharge will obtain increasing like this, thereby make the farther of toxic emission.
Fig. 3 has provided another kind of arc and has accelerated the device that waste gas is discharged, and it is an arc plate 7, and the above has the ventilative through hole of hole shape, and described tail-gas catalyst 4 is bonded on the ventilative through hole, same like this can the tail gas of discharging the purification.The sectional shape of the ventilative through hole of hole shape is trapezoidal, and whole through hole becomes round table-like, and the area of inlet hole is also greater than the area of air outlet hole like this.The speed that waste gas is discharged also will get a promotion.
The device that whole acceleration waste gas is discharged adopts arc to be designed with the discharge that is beneficial to waste gas, certainly arc accelerates the direction that the exhaust extractor radian forms, be that bending direction can change, can form certain radian by convex, the formation certain radian also can concave.Equally, the catalyst material of cleaning of off-gas also can change applicable material type into, and such conversion all drops within the scope of the utility model protection.
