Abstract
The utility model relates to a tail gas purifying silencer for automobiles. The utility model is characterized in that an air inlet pipe, an air distributing box, a front end cap of a shell body and a catalytic chamber 7 are all provided with heat preservation and heat insulation layers. The front end in the shell body is provided with a porous air distributing plate 10 connected with the air inlet pipe with air distributing holes. The catalytic chamber 7 filled with an activated alumina irregular ceramic sphere catalyst carrier with multiple micropores is positioned behind the air distributing plate. Both ends of the catalytic chamber are sealed by stainless steel wire nets. The back end in the shell body is provided with an air distributing pore plate 20 connected with an air outlet pipe. Because of the structure, the utility model has the advantages of simple structure, strong applicability, no occurrence of destructive burning loss to catalysts, good effect of harmful gas and noise pollution elimination, etc. Provided catalyzing conditions can be rapidly adjusted to achieve the optimum state matched with engines.
Description
The utility model relates to the automobile tail gas noise elimination device.
Automobile is the important industry of China, and various vehicle output are doubled and redoubled year by year.But serious day by day automobile exhaust pollution problem has caused great attention.It is poor that the automobile tail gas noise elimination device of domestic employing catalytic cracker exists effect of heat insulation, and temperature can not be concentrated in the media, makes purifying effect poor; And the wear resistance of the carrier of medium is relatively poor.Solve the tail gas clean-up problem if buy external catalytic cracker, costly, be difficult to bear.Some is a difficult problem how to be transformed into emission compliance car etc. with car.
The purpose of this utility model is to provide that a kind of to adopt the many micropores of activated alumina abnormity porcelain ball to do catalyst carrier, simple in structure, the purifying vehicle exhaust silencing apparatus that suitable multiple vehicle is used.
Above-mentioned purpose of the present utility model is to realize by such technological scheme, it is a kind of purifying vehicle exhaust silencing apparatus, comprise housing, suction tude, branch gas tank, housing front cover and rear end cover, catalyst chamber and steam outlet pipe, it is characterized in that: suction tude, divide between gas tank, inlet box front cover interlayer, all be provided with the insulation layer between catalyst chamber and housing; The housing Inner Front End is provided with the porous air dividing plate and divides the suction tude of pore to be connected with band, and the catalyst chamber that is filled with many micropores of activated alumina porcelain abnormity porcelain sphere catalyst carrier is positioned the air dividing plate rear, and its two ends are sealed by Stainless Steel Cloth; The interior rear end of housing has the branch spiracular plate and is connected with the steam outlet pipe in getter hole.
Said structure of the present utility model is further specified by accompanying drawing.
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the structure plan view of special-shaped porcelain sphere catalyst carrier;
Accompanying drawing 3 is the structure side view of special-shaped porcelain sphere catalyst carrier.
Referring to accompanying drawing 1: purifying vehicle exhaust silencing apparatus among the figure, comprise housing 4, suction tude 1, divide gas tank 19, housing front cover 11 and rear end cover 18, catalyst chamber 7 and steam outlet pipe, it is characterized in that: suction tude 1, divide between gas tank 19, inlet box front cover 11 interlayers, catalyst chamber 7 and 4 of housings all be provided with insulation layer 2,12,5; The housing Inner Front End is provided with porous air dividing plate 10 and divides the suction tude of pore to be connected with band, and the catalyst chamber 7 that is filled with many micropores of activated alumina porcelain abnormity porcelain sphere catalyst carrier 3 is positioned the air dividing plate rear, and its two ends are sealed by Stainless Steel Cloth 8; The interior rear end of housing has branch spiracular plate 20 and is connected with the steam outlet pipe 17 in band getter hole.Catalyst chamber 7 among the figure is by positioning ring 9 location, and through hole 16 is communicated with catalyst chamber at the top of housing, and seals with cover plate 14 and screw 15.A preferred embodiment of the present utility model is that a suction valve 21 is set on suction tude 1.
Referring to accompanying drawing 2,3, special-shaped porcelain sphere catalyst carrier 3 described in the utility model has a through hole, and respectively there is 2-8 branch groove 6 such as circumference at the two ends in hole, and two groups of branch grooves such as circumference dislocation are arranged up and down.
The utility model working principle is such: being provided with suction valve 21 on suction tude, in suction tude 1, branch gas tank 19, inlet box front cover 11, catalyst chamber 7 effect of insulation layer being set all is suitable temperature to be provided and to replenish an amount of oxygen condition for catalyzer.Divide gas tank 19 owing to exist between porous air dividing plate 10 and the catalyst chamber,, thereby can make air inlet distribute to catalyzer more equably to react, harmful gas is changed fully simultaneously also because there are the big and microporosity of roughness in the structure of carrier and surface.Air dividing plate 10 and 20 and catalyst chamber in carrier etc. all play the good effect of attenuate acoustic noise, help environmental protection.
The utility model is simple in structure owing to described structure has, adaptability is very strong, the optimum state can very promptly be adjusted, be matched to suitable multiple vehicle, the catalytic condition that provided, catalyzer is not had the advantage such as effective that harmful gas and noise pollution take place, eliminate the destruction. scaling loss.The utility model and electronic fuel injection engine are complementary, and tail gas clean-up will be near-zero release, reach working life more than 100,000 kilometers.
