Abstract
The invention discloses a screw type automobile three-way catalyst. The screw type automobile three-way catalyst is characterized by comprising a front-connection flange, an air inlet pipe, a cylinder and an exhaust pipe; a catalyst module and a liner are arranged in the cylinder; and the catalyst module is of a screw ascending type structure. The screw type automobile three-way catalyst has the beneficial effects that oxidizing time can be prolonged through the catalyst module of the screw ascending type structure, the oxidizing effect is improved, and therefore the use effect of the three-way catalyst is greatly improved.
Description
Technical field
The present invention relates to a kind of screw type automobile three-way catalysts, 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.
In order to realize above-mentioned target, the present invention adopts following technological scheme:
A kind of screw type automobile three-way catalysts, 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 set to spiral formula structure.
Aforesaid a kind of screw type automobile three-way catalysts, is characterized in that, the two ends of described cylindrical shell adopt the cylindrical shell of tapered round platform.
Aforesaid a kind of screw type automobile three-way catalysts, it is characterized in that, described liner is arranged between cylinder inboard wall and catalyst module.
Aforesaid a kind of screw type automobile three-way catalysts, it is characterized in that, described liner is attached on the outer wall of catalyst module.
Aforesaid a kind of screw type automobile three-way catalysts, 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 screw type automobile three-way catalysts, is characterized in that, described outlet pipe is provided with lambda sensor nut.
The beneficial effect that the present invention reaches: the present invention can increase the duration of oxidation by the catalyst module of spiral formula structure, improves oxidation effectiveness, makes the using effect of ternary catalyzing unit greatly improve.
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, 3-catalyst module.
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 screw type automobile three-way catalysts 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; the center lines schematic diagram that 3 in catalyst module 3(accompanying drawing is catalyst modules is provided with in cylindrical shell 1) and liner; wherein; liner is arranged between cylindrical shell 1 inwall and catalyst module 3; preferably; liner is attached on the outer wall of catalyst module 3, although cost can be made like this to improve, can greatly improve for the protection of catalyst module 3 and heat insulation effect.
Catalyst module 3 is set to spiral formula structure, is equivalent to like this elongate the oxidized duration of waste gas, improves oxidation effectiveness, meanwhile, also substantially increases durability degree.
Preferably, catalyst module 3 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.
