Abstract
The utility model relates to a tail gas purifying silencer for motor vehicles, which comprises an air inlet pipe, an air outlet pipe and a cylinder body. The utility model is characterized in that a catalytic chramber composed of a baffle plate and a ventilating plate is arranged in the cylinder body. Rare earth small ball catalysts are arranged in the catalytic chramber. The ventilating plate is a steel wire net plate. The utility model has the advantages of reasonable structure, uniform air flow distribution, small exhaust resistance, good silencing effect, low cost and evident tail gas purifying effect because of the use of rare earth element catalysts. The utility model is favorable for improving the power performance and economy of vehicles.
Description
The utility model belongs to the motor vehicle tail-gas purifying silencing equipment.
Existing motor vehicle tail-gas purifying silencer mostly is a bushing type, and its shortcoming is easily to produce resonance, the tail gas clean-up weak effect, and exhaust resistance increases, and vehicle power, Economy have bigger influence.
The purpose of this utility model provides a kind of rational in infrastructure, air-flow is evenly distributed, exhaust resistance is little, noise elimination is effective, tail gas clean-up can be up to standard motor-vehicle tail-gas silencing apparatus.
The utility model comprises suction tude, steam outlet pipe, cylindrical shell, it is characterized in that being provided with the catalyst chamber that is made of baffle plate and air permeable plate in the cylindrical shell, and the rare earth pellet catalyst is housed in the catalyst chamber.Air permeable plate can be expanded sheet metal.
The utility model is rational in infrastructure, air-flow is evenly distributed, exhaust resistance is little, noise elimination is effective, adopt the rare earth elements catalyzer, the tail gas clean-up effect is remarkable, and low price, and the utility model is eliminated the noise with existing purification and prepared power character and the Economy that helps improving vehicle.
The utility model is further specified as follows below in conjunction with accompanying drawing:
Fig. 1 is a positive view of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 1.
Shown in Fig. 1～3, the utility model comprises suction tude 1, steam outlet pipe 2, cylindrical shell 3, it is characterized in that being provided with the catalyst chamber that is made of baffle plate 4,5 and air permeable plate 6,7 in the cylindrical shell 3, and rare earth pellet catalyst 8 is housed in the catalyst chamber.Air permeable plate 6,7 is an expanded sheet metal.
Working principle of the present utility model is, tail gas is in suction tude 1 is advanced cylindrical shell body 3, air hole through air permeable plate 6 enters catalyst chamber, tail gas fully contacts with rare earth pellet catalyst 8 in catalyst chamber, and reaction temperature is suitable, harmful element is purified, and purified gas is discharged through cylindrical shell 3 and air outlet 2 through the air hole of air permeable plate 7 again.
Claims (2)
