Abstract
The invention discloses an automobile three-way catalyst convenient to clean. The automobile three-way catalyst convenient to clean is characterized by comprising a front connecting flange, an air inlet pipe, a barrel body and an air exhausting pipe, wherein a catalyzer module and a liner are arranged in the barrel body; the catalyzer module is provided with three layers including a first layer of catalyzer module, a second layer of catalyzer module and a third layer of catalyzer module which are sequentially communicated; the end of the air inlet pipe is connected with the first layer of catalyzer module; the third layer of catalyzer module is connected with the end of the air exhausting pipe. The automobile three-way catalyst convenient to clean has the beneficial effects that due to the design of the three layers of the catalyzer module, impurities with larger particles are basically stayed in the first layer of catalyzer module, and the first layer of catalyzer module needs to be cleaned seriously during detachment and cleaning; if the first layer of catalyzer module is blocked or oxidized seriously, the first layer of catalyzer module can be replaced independently. Meanwhile, the time of waste gas staying in the catalyzers is prolonged, the catalyzing effect is improved, and the catalyzing efficiency can be greatly improved.
Description
Technical field
The present invention relates to a kind of automobile three-way catalysts being convenient to clean, belong to automobile mechanical technical field.
Background technique
The ternary catalyzing unit of automobile improves motor vehicle emission, reduces the vitals of automobile exhaust pollution.But along with the growth of service time, carbon distribution in vehicle exhaust, sulfur-bearing, phosphorous compound can deposit on the catalyst surface on three-way catalytic converter carrier, cause catalyst poisoning, catalytic efficiency decline, greatly reduce ternary catalyzing unit to purifying vehicle exhaust effect.
The problem that current most of ternary catalyzing unit runs into is exactly along with using the increase of duration, making oxidation effectiveness worse and worse, although regular cleaning is necessary, the cycle is too short will bring very large puzzlement to use.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide the ternary catalyzing unit that a kind of durability degree is high, for the cleaning after dismounting, improve efficiency.
In order to realize above-mentioned target, the present invention adopts following technological scheme:
Be convenient to the automobile three-way catalysts cleaned, it is characterized in that, comprise front acting flange, suction tude, cylindrical shell and outlet pipe; Catalyst module and liner is provided with in described cylindrical shell; Described catalyst module is provided with three layers, is respectively the first layer catalytic module, second layer catalytic module and the third layer catalytic module that are communicated with successively; The end of described suction tude is connected with first layer catalytic module; Described third layer catalytic module is connected with the end of outlet pipe.
Aforesaid a kind of automobile three-way catalysts being convenient to clean, it is characterized in that, the two ends of described cylindrical shell adopt the cylindrical shell of tapered round platform.
Aforesaid a kind of automobile three-way catalysts being convenient to clean, it is characterized in that, described liner is arranged between cylinder inboard wall and catalyst module.
Aforesaid a kind of automobile three-way catalysts being convenient to clean, it is characterized in that, described liner is attached on the outer wall of catalyst module.
Aforesaid a kind of automobile three-way catalysts being convenient to clean, it is characterized in that, described catalyst module inner homogeneous is provided with orthohexagonal support body, and support body is distributed with catalyzer.
Aforesaid a kind of automobile three-way catalysts being convenient to clean, is characterized in that, described outlet pipe is provided with lambda sensor nut.
The beneficial effect that the present invention reaches: the foreign material that the design of three layers of catalytic module makes particle larger are trapped in first layer catalytic module substantially, when carrying out disassembly, cleaning, first layer catalytic module is needed to carry out the clean of emphasis, if blocking or oxidized very serious, can change separately, simultaneously, also increase the waste gas time in the catalyst, improve catalytic effect, catalytic efficiency can be improved widely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The implication of reference character in figure:
1-cylindrical shell, 2-lambda sensor nut, 301-first layer catalytic module, 302-second layer catalytic module, 303-third layer catalytic module, 4-suction tude, 5-outlet pipe.
Embodiment
The invention will be further described below.Following examples only for technological scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
A kind of automobile three-way catalysts being convenient to clean that the present invention relates to, comprises front acting flange, suction tude, cylindrical shell 1 and outlet pipe.Outlet pipe is provided with lambda sensor nut 2.
The two ends of cylindrical shell 1 adopt the cylindrical shell of tapered round platform, are provided with catalyst module and liner in cylindrical shell 1, and wherein, liner is arranged between cylindrical shell 1 inwall and catalyst module, and preferably, liner is attached on the outer wall of catalyst module.
Catalyst module is provided with three layers, is respectively the first layer catalytic module 301, second layer catalytic module 302 and the third layer catalytic module 303 that are communicated with successively.The end of suction tude 4 is connected with first layer catalytic module 301, and third layer catalytic module 303 is connected with the end of outlet pipe 5.For the ease of the air-flow in catalyst module, as shown in Figure 1, the joint of three layers of catalytic module is provided with curved corners.Adopt the structure of three layers of catalytic module, be equivalent to elongate the oxidized duration of waste gas, improve oxidation effectiveness, meanwhile, also substantially increase durability degree.
In cleaning, the foreign material that particle is larger are trapped in first layer catalytic module 301 substantially, need to carry out the clean of emphasis, if blocking or oxidized very serious, can change separately, comparatively speaking two-layer in addition, only need to clean normally and reduction treatment, also optionally to change after using over a long time, but relative to the replacement frequency of prior art, greatly reduce.
Preferably, catalyst module inner homogeneous is provided with orthohexagonal support body, and support body is distributed with catalyzer.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
