Description

A kind of exhaust silencing purifier for pressure combustion diesel engine

The utility model is a kind of exhaust silencing purifier for pressure combustion diesel engine, belongs to the technical field of diesel engine silencing apparatus.

In the prior art, for noise elimination, the general silencing and purifying device of purified treatment employing of motor, this device noise elimination purifying effect is unsatisfactory, and is particularly bad especially for diesel engine; Someone has invented the silencing and purifying device of making of lamination coating, and this product has certain effect, but because the lamination coating reliability is not high, often causes silencer to damage easily, and also still can not solve the problem of Purge gas.

The purpose of this utility model is: a kind of product that can obviously eliminate the noise and can purifying exhaust gas gas is provided, this product utilization exhausting air is to the absorption of infrared rays energy, decompose and the oxidizing gas composition, make sufficient combustion, thereby be converted into the method for innocuous gas; The principle of this device is: based on the catalyst technology of reactor mode, utilize catalysis material to produce far-infrared spectrum ripple (heat energy of gas) during work, GAS ABSORPTION far-infrared spectrum ripple causes the reaction of chemical particle.The far-infrared spectrum ripple send by air-flow, and air-flow is the oxygen of conditioned reaction again, causes the oxidation of various compositions, when particulate is produced useful effect, has also reduced CO (carbon monoxide), HC (hydrocarbon) and NO2 (oxynitrides).

The utility model is to constitute like this: it is by advancing, outlet pipe (1), (4), silencer (3) and shell (11) constitute, between silencer (3) and shell (11), be mounted with purification pipe (6), between silencer (3) and shell (11), be mounted with purification pipe (6), metal purification ring (7) is installed on the purification pipe (6), the two ends of shell (11) connect respectively into, outlet pipe (1), (4), purification pipe (6)-end connection suction tude (1), in addition-hold the air outlet (12) that is connected silencer (3) to form a sealed cavity (5), the outer suit one of purification pipe (6) is undulatory metal purification ring (7), there are vent (10) or groove in the two ends of shell (11), install in the purification pipe (6), fixing silencer (3).

Accompanying drawing 1 is a structural representation of the present invention, and accompanying drawing 2 is installment state figure of the present invention.

In accompanying drawing 2, A is an explosive motor; B is the engine exhaust house steward; C is that engine exhaust pipe is suction tude (1), and D is the utility model.

Compared with prior art, the utility model it the particulate that all emission gases and some gases form is risen Effect, reduce CO (carbon monoxide), CO2 (carbon dioxide), NOx (oxynitrides), HC (hydrocarbon) and opacity. Simultaneously because catalysis material does not directly contact this dress with gas Putting does not need to safeguard, can not induce reaction yet, and does not produce saturated. More conventional catalyst converter is more economical, durable, Effectively. Can effectively various pollutants be reduced more than 50%, and can guarantee that running car uses 300,000 The kilometer or 3 years. Simultaneously efficient is all very high under high temperature, cryogenic conditions, install also convenient, fast, Long service life, expense is low, and is respond well;

Embodiment of the present utility model: the two ends of metal shell (11) connect air inlet and exhaust piper (1), (4) respectively, the air outlet (12) that the one end connection suction tude (1) of purification pipe (6), the other end are connected silencer (3) forms a sealed cavity (5), the outer suit of purification pipe (6), parcel one are undulatory metal purification ring (7), there is vent (10) at the two ends of shell (11), install in the purification pipe (6), fixing aperture silencer (3).It is work like this: the gas that motor (A) is discharged through outlet pipe (C), enters the sealed cavity (2) of purification plant along exhaust manifold (B) again by the suction tude (1) of purification plant (D).At this, the pressure of gas diminishes, and begin to enter preceding half section for to be covered with in the silencer (3) of aperture collapsible tube, because the effect of aperture on the pressure change of gas and the collapsible tube produces good noise elimination effect.Simultaneously, gas in collapsible tube is owing to be compressed, its pressure, temperature, speed all rise, so when gas has jet-action when silencer (3) enters taper outlet pipe (4), thereby in annular space (5), produce hypotensive effect, make pressure in this space less than ambient atmosphere pressure; Therefore ambient atmosphere is just by this device and extraneous through hole (10), through metal purification ring (7), enter purifier inside, arrive annular space (5), thereby form the atmospheric air circulation, in addition, because high temperature is air-flow process sealed cavity (2) continuously, pure metal purification ring (7) temperature rising that makes its metal purification pipe (6) and be wrapped in its appearance, thus infrared can the radiation (these radioactive rays comprise all infrared spectrums, promptly from 600cm-l to 4000cm-1) produced.This electromagnetism infrared rays passes metal purification ring (7) by radiation, when metal purification ring (7) is heated up, also because the effect of metal purification ring makes the ultrared frequency of electromagnetism produce change, and becomes the infrared spectrum that organic compound can preferential absorption.Therefore pass through the purifier connecting port when ambient atmosphere,, when arriving annular space (5), outer atmospheric temperature is risen, also the electromagnetism infrared rays has been imported annular space through the metal purification ring.So when the waste gas that comes out from sealed cavity (2) finally mixed firing chamber (8) with ambient atmosphere, because ambient atmosphere has not only also been come abundant oxygen, the while had also imported the infrared spectrum that organic compound can preferential absorption.So all gases composition that motor is discharged obtains sufficient oxidation and decomposition.Be discharged in the atmosphere again after changing it into innocuous gas, pollute thereby reduce greatly.
