Abstract
The utility model discloses an automobile tail gas purifying silencer which is characterized in that a middle segment in a cylindrical cylinder body is provided with an isolating catalytic bed to cause harmful gas in tail gas to be well purified and silenced, and the spark is extinguished, when the harmful gas penetrates through the catalytic bed. The automobile tail gas purifying silencer is an ideal device for purifying and silencing the tail gas of an automobile and extinguishing spark.
Description
The utility model relates to a kind of fuel engine tail gas purification silencer, particularly purifying vehicle exhaust silencing apparatus.
Be used for the purifying vehicle exhaust silencer at present, the multidisc of employing ceramic honeycomb catalyzer filtration, purification mode is arranged, it is bad that its shortcoming is that discharge tail gas purifies, and noise does not reduce.After, people improve again and designed new purifying vehicle exhaust silencing apparatus, and are described as China Patent No. 91210748.0 specifications, its structural principle is to allow tail gas enter purifying chamber and buffer cell by suction tude, by catalytic bed catalysis, tail gas is purified indoor, has also reduced noise simultaneously.But because perfect not to the utmost on this utensil structure, the tail gas clean-up effect is also not so good, and working life is shorter.
Task of the present utility model provides the device of a kind of high efficiency resistance spark-extinguishing and purifying automobile tail gas.
Task of the present utility model can realize by following scheme: the stage casing at the cylindrical tube of closed at both ends is provided with the isolation catalytic bed that can breathe freely that catalyzer is housed, catalytic bed is the exhaust buffer cell on one side, another side is the air inlet purifying chamber, the suction tude of passing and being fixed in an end cap and isolating catalytic bed extends in the air inlet purifying chamber, passes and the outlet pipe that is fixed in another end cap and isolates catalytic bed extends in the exhaust buffer cell.
Isolate the wallboard of catalytic bed and can make sieve aperture shape or netted shape.Be convenient to gas flow like this.
The utility model with following advantage is compared with prior art arranged:
(1) adopts above-mentioned isolation catalytic bed structure, can improve the tail gas clean-up effect greatly, make the tail gas clean-up rate improve CO18%, HC15% than original technology.
(2) the spark-extinguishing efficient height of resistance makes exhaust emissions not be with spark.
(3) can increase the service life more than one times.
Below in conjunction with drawings and Examples the utility model is described further.
Accompanying drawing 1 is the structural representation of purifying vehicle exhaust silencing apparatus of the present utility model.
As shown in drawings, the purifying vehicle exhaust silencing apparatus is the improvement to original technology.The purifying vehicle exhaust silencing apparatus is made up of cylindrical tube 1, end cap 2, end cap 3, suction tude 4, outlet pipe 5, isolation catalytic bed 6, purifying and catalyzing bed 7, air inlet purifying chamber 8 and exhaust buffer cell 9.Cylindrical tube 1, suction tude 4, outlet pipe 5, roll with the book steel plate and to form, suction tude 4 and outlet pipe 5 are made according to original technology, have noise elimination function.End cap 2 and 3 usefulness sheet metal punching presses are made.Make netted shape or stamp out many holes isolating catalytic bed 6 wallboards 10 and 11 earlier.Passing the one side that isolates catalytic bed 6 wallboards, welding is suction tude 4 fixedly, and another side then welds fixedly outlet pipe 5, isolates placement catalyzer in the middle of catalytic bed 6 wallboards 10 and 11.Then, put in the cylindrical tube together with suction tude and outlet pipe isolating catalytic bed, fix in the stage casing of cylindrical shell, last, two of cylindrical shell puts end cap, and sealing is welded and is purifying muffler.
Purifying vehicle exhaust silencing apparatus of the present utility model, its working principle is such: be subjected to the catalysis of purifying and catalyzing bed and the harmful gas in the tail gas is purified after tail gas enters the air inlet purifying chamber by suction tude, purified gas passes the isolation catalytic bed, further make harmful gas be able to better purification, the gas that is fully purified enters the exhaust buffer cell at last and is discharged by outlet pipe.Entered by suction tude at tail gas, the whole process of discharging from outlet pipe also is a noise reduction, hinders spark-extinguishing process, so utensil of the present utility model is the device of a multi-functional purifying vehicle exhaust, resistance spark-extinguishing, noise elimination noise reduction.
Claims (2)
1, a kind of purifying vehicle exhaust silencing apparatus, formed by cylindrical tube, end cap, suction tude, outlet pipe, purifying and catalyzing bed, its characteristics are that the stage casing in cylindrical tube is provided with the isolation catalytic bed that can breathe freely that catalyzer is housed, it is the exhaust buffer cell on one side, another side is the air inlet purifying chamber, the suction tude of passing and being fixed on an end cap and isolating on the catalytic bed extends in the air inlet purifying chamber, and the outlet pipe that passes and be fixed on another end cap and the isolation catalytic bed extends in the exhaust buffer cell.
2, purifying vehicle exhaust silencing apparatus according to claim 1 is characterized in that the wallboard of isolating catalytic bed is the sieve aperture shape or is netted shape.
