Abstract
The utility model relates to a purifying and sound eliminating device of exhaust for motor vehicle, belonging to the technical field of the exhaust gas purification, the noise reduction and the sound elimination of motor vehicle internal-combustion engine and solving the problems of the conversion of harmful ingredient and the exhaust noise reduction in the exhaust gas process of the motor vehicle. The utility model is characterized in that the high temperature resistant adhesive is filled between a cylindrical or elliptical metal shell both ends of which are taper-shaped and a catalysis device with a ceramic beehive carrier to solve the shockproof of the ceramic carrier, make the ceramic carrier difficult to crush and achieve the heat insulation function for catalytic combustion.
Description
The utility model is relevant with attenuating Motor Vehicle noise with purifying exhausted gas of motor vehicle, belongs to the technical field that Purification of IC Exhaustive Gas and noise abatement are eliminated the noise.
The waste gas that Motor Vehicle is discharged contains multiple harmful substances, as carbon monoxide, hydrocarbon, nitrogen oxide etc.Existing technology is to adopt the method for catalytic combustion to be removed.Generally be that the carrier that soaked catalyzer is packed in the columned metal shell, be installed in the outlet pipe place of motor car engine then.Prior art shows select for use the ceramic honeycomb carrier to purifying the gas and the reducing noise of discharging effect preferably to be arranged, but this kind carrier has an outstanding shortcoming, is exactly broken easily.The inventor retrieves and has consulted relevant document of 1974-1987 and data, as: CN86100318A, CN85102816A, DE3224224A, DE3238010A, JP51-87482A, JP52-33880A, JP55-165270A, JP56-81135A, JP57-26220A, JP61-4812A, JP61-4813A, US3937617, US4456457, US3963445 and Germany 1987 are at the showpiece of Beijing environmental protection exhibition etc., and finding the broken problem of domestic and international resolved vector has three kinds of ways: the first is twined high temperature resistant spring steel silk screen around carrier; It two is to load shockproof exotic material between catalyst carrier and housing; It three directly tightly is stuck in carrier on the housing.The technology difficulty that above method has is big, material expensive and home made materials are difficult for solving, though have use material economy, lack working life.
The utility model is that existing apparatus is proposed to be suitable for practical new technological scheme, the purifying vehicle exhaust gas silencing apparatus of making can overcome above-mentioned deficiency, adopt cheap material and reliable technology, solved to load onto and in long-play, be difficult for behind the ceramic honeycomb carrier brokenly, reached further purifying exhaust air simultaneously and reduce the requirement of noise.
Structure of the present utility model as shown in the figure, when high temperature heat wave air-flow is discharged from cylinder, feed the inlet cone end of round metal (or oval) tubular device of two end topers, by the striking plate of certain punching rate is arranged, air-flow is more equably by the ceramic honeycomb carrier catalyzer, combustion reaction takes place in waste gas under catalyst action, make harmful components be converted into innocuous gas, discharges via another awl end relief opening then.Turnover two awl end osculum diameters are 48 millimeter, housing is more piece metal cylinder shell (or cylindroid shell), its internal diameter is at 110 millimeter (or 180 * 110 millimeters) (can add certain interval according to selected catalyst carrier external diameter determines), in dress diameter 95-100 millimeter (or 170 * 100 millimeters) ceramic honeycomb carrier catalyzer, between itself and shell, fill high temperature resistant binder.This Bond is to form with material blendings such as high temperature resistant chemical glue and aluminum silicate fibers.Respectively be bumped into a stainless steel protection end cover at the carried catalyst two ends, compress spot welding with metal washer and fix.The size of shell and length can decide the length of catalyst-assembly and shell according to discharge capacity, power, rotating speed, the oil consumption of motor, can be one the joint (unit), also can be more piece (multiple-unit), can make a complete purifying muffler with welding method.Turnover gas coning end and shell make two and half housing stamping part as a whole, are convenient to load ceramic honeycomb carrier catalyzer and high temperature resistant binder.
The utility model compared with prior art has the following advantages and good effect:
1, one deck high temperature resistant binder is arranged between honeycomb ceramic carrier and the shell, have insulation and antihunt action, make the existing waste gas burning that does well out of of carrier be difficult for broken again.
2, air inlet slows down airspeed and changes direction by the striking plate of certain punching rate is arranged.Leave certain space between one group of carrier and another group carrier, waste gas is mixed again, again by the catalyzer burning, sufficient reacting, while carrier etc. has good sound-absorbing performance, constitutes the combined type impedance silencer.
3, this device selects for use homemade ceramic honeycomb carrier catalyzer to assemble, the actual use in domestic automobile (Beijing 130, Beijing 212, Beijing 121), to replace original silencing apparatus, go through loading transportation in summer in winter, operation on the daily output Toyota pick up truck all more than 60,000 kilometers.The experimental result ceramic honeycomb carrier is intact, does not have broken situation to take place.CO, HC purifying effect and noise emission all be lower than national regulation related standards (GB3845--83, GB1495--79).
4, the utility model can be applicable on various gasoline, diesel car and the internal combustion locomotive, adopts home made materials, and is with low cost.Economy and environmental benefit are all better.
Embodiment of the present utility model sees shown in the figure.
I. C. engine exhaust feeds inlet cone end (1).By striking plate (2), gas stream, is discharged by going out gas coning end (8) after harmful gas fully burns and purifies through ceramic honeycomb carrier catalyzer (3).Housing (4) is a joint or a more piece cylindrical body; fill the high temperature resistant stick (7) of 3-15 millimeter between housing (4) and the carrier (3); the carried catalyst two ends respectively are bumped into stainless steel protection end cover (5); compress spot welding with metal washer (6) and fix, the temperature measuring of inlet, outlet and gas sampling joint (9).
Claims (3)
1, a kind of by the ceramic honeycomb carrier catalyzer be main body, the round metal column casing of two end topers of packing into or the purifying vehicle exhaust gas silencing apparatus in the oval column casing, it is characterized in that inlet end is provided with buffer gas flow noise abatement striking plate, between catalyzer and housing, fill high temperature resistant binder, it also can be polylith that catalyzer can be one, studs with protection end cover at the two ends of every catalyzer; And compress spot welding with packing ring and be fixed on the housing.
2, purifying muffler as claimed in claim 1 is characterized in that high temperature resistant binder is to form with high temperature resistant chemical glue, aluminosilicate fiber cotton and the blending of potting powder.
