Description
Technical field
The utility model belongs to the accessory of I. C. engine, a kind of specifically internal combustion engine purification baffler.
Background technique
The internal-combustion engine baffler is the indispensable annex of explosive motor, and its effect is the noise that reduces motor.Country realizes that by the improvement to motor the possibility of emission compliance is very little after the exhaust emissions of internal-combustion engine is carried out the pressure standard.And human more and more higher to requirement on environmental protection, countries in the world are also improving constantly the exhaust emission standard of explosive motor.China is to the also revision thereupon of exhaust emission standard of explosive motor.Existing internal-combustion engine baffler does not install exhaust gas cleaner basically additional, and this is the deficiencies in the prior art and need carry out improved reason just.
Summary of the invention
The purpose of this utility model provides a kind of tail-gas purifying muffler for internal combustion engine.Utilize baffler to belong to the characteristics of the indispensable annex of explosive motor, install exhaust gas cleaner additional, make it, realize tail gas clean-up function explosive motor keeping eliminating on the basis of engine noise function in baffler inside.
Specifically, a kind of tail-gas purifying muffler for internal combustion engine, has suction tude (1), cylindrical shell (8), outlet pipe (10), suction tude (1) middle part is fixed in the left end cap (2) of cylindrical shell (8), the middle part of outlet pipe (10) is fixed in the right end cap of cylindrical shell (8), being connected with the surface at the end of suction tude (1) scribbles exhaust gases of internal combustion engines is had absorption, oxidation, the netted noise reduction purification pipe (4) of the noble metal catalyst of catalysis, and the front and rear at netted noise reduction purification pipe (4) all adds dividing plate (5), the preceding silk screen (6) that is fixed with of dividing plate (5) is equipped with activated adsorption thing (7) in the silk screen (6).
Big discharge capacity starts exhausted air quantity bigger, and purification pipe can not guarantee the purifying effect to tail gas.For adapting to the needs of large-duty engine, a plurality of netted noise reduction purification pipes can be installed in parallel on dividing plate (5), and the end in suction tude (1) adds cellular purifier (3), and this purifier (3) faces netted noise reduction purification pipe (4) and its surface scribbles the noble metal catalyst that exhaust gases of internal combustion engines is had absorption, oxidation, catalysis.
Working principle of the present utility model: the effective clip chucking of part 2 (suction tude) outer end and engine exhaust, the tail gas that motor is discharged enters part 3 (cellular purifier) through part 2 (suction tude) tail gas is made purified treatment.Part 3 (cellular purifier) is to scribble platinum, rhodium, palladium etc. to CO, NO by the surface
x, the metallic carrier of HC with noble coatings of absorption, oxidation, catalysis make.Gas after the purified treatment enters part 4 (netted noise reduction, purification pipe) noise reduction spraying to part 6 (silk screen) under the engine pressure effect and gas is purified once more after part 7 (granular activated alumina) is to oil vapour and particulate material absorption.Part 4 (netted noise reduction, purification pipe) mesh portion scribbles precious metals such as platinum, rhodium, palladium equally.Part 7 on the rear bulkhead (granular activated alumina) is once more to oil vapour and particulate material absorption.Discharge from part 10 (outlet pipe) through noise reduction, purified gas.The gas that discharge this moment is the gas that reaches emission standard.
In concrete the application, can according to concrete type, structure and performed standard-required determine to precious metals such as platinum, rhodium, palladiums content (being the thickness of noble coatings) how much.
This technology is to be based on prior art, adopt international advanced and mature tail gas clean-up technology and device, collection noise reduction and tail gas clean-up function are one, on the basis that does not change motor original structure and connecting mode, easy, realized that noise eliminates and tail gas clean-up two big functions reliably, effectively.Meet the industrial development direction of country and the fundamental state policy of implementation environmental protection, the market potential tool is big, and development prospect is wide.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
The utility model is by the air inlet cleaning system; Absorption, purification, silene system; Housing three parts are formed.The air inlet cleaning system is by part 1 (suction tude), part 2 (left end cap), and part 3 (cellular purifier) welding combines.Absorption, noise reduction, cleaning system are by part 4 (netted noise reduction purification pipe), part 5 (dividing plate), and part 6 (silk screen), part 7 (granular activated adsorption thing) is through welding, bonding combining.Housing is by part 8 (cylindrical shell), part 9 (right end cap), and part 10 (outlet pipe) welding combines.The part 5 (two dividing plates) of absorption, noise reduction, cleaning system is made up with part 8 (cylindrical shell) welding of housing.Again with part 8 (cylindrical shell) the welding combination of part 2 (left end cap) and housing (one side of silk screen is housed on the dividing plate end that Assemble fashion clothing has a part 3 inwards).Part 8 (cylindrical shell) the welding combination of part 9 (right end cap), so just finished the assembling of tail-gas purifying muffler for internal combustion engine at last with housing.
Requirement according to the size of engine exhaust amount and emission standard is different, can select to adopt wherein a kind of in cellular or the mesh-like purification style; Structurally can adopt the netted noise reduction purification pipe of single tube or multitube.When adopting the single tube structure, do not install cellular purifier additional, and part 1 (suction tude) and part 4 (netted noise reduction, purification pipe) soldering group are integrated.This structure is applicable to minicomputer.
