Abstract
The utility model provides an exhaust pump oxygenation purifying device for an engine, which is characterized in that the utility model is composed of a waste gas inlet port 1, a purifier 3 loaded with catalyst, an air pipe 4 of which one end is communicated with the waste gas inlet port 1, a waste gas outlet port 10 arranged at the back face of the purifier 3 and an air pump 6 connected with the other end of the air pipe 4, wherein, the air pump 6 is an electric air pump; the oxygen content in the waste gas is enhanced through adding air before the purifier with the catalyst, making the catalyst produce reaction and making CO content and HC content in the waste gas lower, and the effect of reducing pollution is attained. The utility model has the advantages of simple structure and reliable operation, and is an effective device for environmental protection.
Description
Traditional vehicle engine exhaust gas purifies the modes that adopt catalyzer to purify more, though can produce certain purifying effect, owing to carbureter engine because of oxygen content deficiency in the waste gas of discharge, and react insufficient, so effect is bad.
The purpose of this utility model just provides oxygen content in a kind of increase waste gas, and catalyzer can fully be reacted, thereby reaches the aeration device of engine exhaust catalyticing purifying effect.
Content of the present utility model is such.First kind of scheme be by exhaust gas entrance 1, and the tracheae 4 that purifier 3, one ends of catalyzer are communicated with exhaust gas entrance 1 is housed, the waste gas outlet 10 of purifier 3 back, and the air pump 6 that links to each other with tracheae 4 the other ends is formed.Described air pump 6 is an electric air pump.Second kind of scheme is by exhaust gas entrance 1, the purifier 3 of catalyzer is housed, the tracheae 4 that one end is communicated with exhaust gas entrance 1, the waste gas outlet 10 of purifier 3 back, be positioned at the turbine air pump 6 that waste gas outlet 10 links to each other with tracheae 4 the other ends, air inlet 7 on the turbine air pump 6, the air inlet pipe 8 that communicates with air inlet 7 is formed.Described turbine air pump 6 is such, by a turbine 14 that is positioned at relief opening 10, drive wheel 12 by the turbine shaft drive, by the connecting rod 16 that drive wheel 12 drives, the pump housing 20 is by the pump valve 17 that moves in the pump housing 20 of connecting rod 16 drives, safety check 18 before the pump valve 17, the end cap 19 of the pump housing, the air outlet slit 11 behind the safety check, the air inlet 20 of pump valve middle of stroke is formed on the pump housing 20.Described drive wheel 12 is cam or is bent axle.
Effect of the present utility model is such, and first kind of scheme is to use electric air pump to add air in catalyzer purifier front exhaust pipe, improved the oxygen content in the exhaust greatly, guarantees the required oxygen content of catalyst reaction.Second method is to utilize the speed of automobile exhaust gas discharge very fast, has very big energy, utilize its impulse force, drive the turbine high speed rotating, drive air pump and air is joined in the waste gas of motor discharge, improve oxygen content, make the waste gas that enters purifier can carry out catalytic reaction.Reach purification effects.
