Abstract
The utility model relates to an end gas purifying device for a car, which comprises a casing, an air inlet and an air outlet which are arranged on the two ends of the casing and is characterized in that metallic packing is filled in the air inlet in the casing and activated carbon is filled in the air outlet in the casing. The utility model can effectively reduce harmful substances in the end gas when a car is in a cold starting mode and is especially adapted to the car which is provided with the end gas purifying device at prevent. The utility model can make up for the defect of poor end gas purifying effect which the car is in the cold starting mode. Secondary combustion can be carried out to the harmful substances in the exhausted end gas of the car by the structure, and the end gas purifying effect is evidently increased. Meanwhile, the technical scheme also has the advantages of simple structure, good purifying effect, etc.
Description
Technical field
The utility model relates to a kind of automobile exhaust purifier.
Background technique
Automobile exhaust pollution has become the main source of pollution of atmosphere.Present 5.5 hundred million meters of world car recoverable amount, annual automobile row to the harmful matter of atmosphere up to 7.15 hundred million tons.At 30-50 from now on, fuel-engined vehicle will be the main product of automotive industry, reduces the discharge amount of harmful matter hydrocarbon, nitrogen oxide and carbon monoxide in the vehicle exhaust, has become " bottleneck " of restriction automobile industry development.In recent years, pay much attention to the work of purifying vehicle exhaust Study on Technology both at home and abroad.High strength of the prior art, high temperature oxidation resisting foamed conducting ceramic material have been applied to electric heating to be strengthened in " triple effect " arrangement for catalytic purification, this new purification technics is except that the advantage that has kept metal electric heating reinforcement technique, required power conditions can be provided by existing vehicle-mounted electric power system fully, and this technology can also be used for diesel car tail gas refining, can form and eliminate soot and nitrogen oxides simultaneously.But, but because its low temperature active is poor, initiation temperature higher (generally greater than 200 ℃), thereby the tail gas clean-up effect is relatively poor when causing cold-starting automobile.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, and a kind of automobile exhaust purifier of harmful substance contents in the tail gas can effectively reduce cold-starting automobile the time is provided.
For realizing the purpose of this utility model, the technological scheme that adopts is: a kind of automobile exhaust purifier, comprise housing and the inlet and outlet mouth that is installed in the housing two ends, it is characterized in that the inlet end in housing is equipped with metallic stuffing, the exhaust end in housing is equipped with active carbon.
Above-mentioned metallic stuffing is the foaming metal material, and the foaming aperture of foaming metal is the 50-1200 micron, and porosity ratio is 80-98%.
Above-mentioned metallic stuffing is rolled into by the sheet metal spiral of band through hole.
Characteristics of the present utility model are when cold-starting automobile, because existing exhaust gas cleaner also can't proper functioning, a large amount of tail gas that are not cleaned enter in the purifier of the present utility model, by in this purifier metallic stuffing being arranged, metallic stuffing is just being adsorbed the harmful matter that motor car engine produces thereon, because the gas temperature of discharging from motor is very high, metallic stuffing is heated by high temperature, the metallic stuffing of high temperature is carried out secondary combustion to harmful matter attached thereto, has removed the harmful matter in the motor vehicle emission tail gas.Simultaneously, the active carbon in the purifier can adsorb the gas that environment is worked the mischief effectively, has reached the purpose of this utility model.This purifier very is fit to install at present the automobile of tail gas clean-up, and this relatively poor defective of tail gas clean-up effect can obviously reduce harmful gas emission in the vehicle exhaust in the time of can remedying cold-starting automobile.This structure also has advantages such as simple in structure, good purification.
Description of drawings
Fig. 1 is the structural representation of the utility model mode of execution;
Fig. 2 is the structural representation of the another kind of mode of execution of the utility model.
Embodiment
As shown in Figure 1, left end at housing 2 is fixed with suction port 1, be fixed with relief opening 5 at right-hand member, suction port 1 links to each other with exhaust opening of engine, suction port 1 also can link to each other with existing automobile exhaust purifier, left end in housing 2 is equipped with metallic stuffing 3, right-hand member in the housing 2 is equipped with active carbon 4, motor is when starting, because existing automobile exhaust purifier does not also reach initiation temperature, just at first do not enter in the purifier by suction port 1 through the tail gas that purifies like this, by the filtration of metallic stuffing, harmful matter is attracted in the metallic stuffing, because the gas temperature of discharging from motor is very high, metallic stuffing is heated by high temperature, and the metallic stuffing of high temperature is carried out secondary combustion to harmful matter attached thereto, has removed the harmful matter in the motor vehicle emission tail gas.Tail gas after filtering through metallic stuffing is when the active carbon by right-hand member in the housing 2, and harmful matter is filtered again, thereby is harmful to the discharging of tail gas can prevent cold start-up effectively the time.
Metallic stuffing is formed for the foaming metal material, and micron can be designed as required at 50-1200 in the foaming aperture of foaming metal, and porosity ratio is 80-98%.Preferred foaming aperture is between the 400-800 micron, and porosity ratio is 95-98%.
As shown in Figure 2, metallic stuffing 3 can be rolled into by the sheet metal spiral of band through hole, black smoke particulate in the tail gas is adsorbed by the metal spiral plate with through hole, the aperture of through hole is hunted down by described metal throuth hole for making the black smoke particulate in the tail gas, the temperature gas of being discharged by motor heats the sheet metal of through hole again, absorption harmful substances is thereon carried out secondary combustion, the discharging of harmful tail gas when having solved cold-starting automobile.
Claims (3)
1, a kind of automobile exhaust purifier comprises housing and is installed in the inlet and outlet mouth at housing two ends, it is characterized in that inlet end in housing (2) is equipped with the exhaust end of metallic stuffing (3) in housing (2) active carbon (4) is housed.
2, a kind of automobile exhaust purifier according to claim 1 is characterized in that above-mentioned metallic stuffing (3) for the foaming metal material, and the foaming aperture of foaming metal is the 50-1200 micron, and porosity ratio is 80-98%.
3, a kind of automobile exhaust purifier according to claim 1 is characterized in that above-mentioned metallic stuffing (3) is rolled into by the sheet metal spiral of band through hole.
