Description
Technical field
The present invention relates to vehicle maintenance service apparatus field, is a kind of ternary catalyzing unit especially.
Background technology
After being burnt due to automobile gasoline, a large amount of pernicious gases are produced, mainly including carbon monoxide, hydrocarbon, nitrogen oxygen
Compound；This kind mixing pernicious gas is handled using ternary catalyzing unit therefore, being typically necessary, it is generated carbon dioxide
And water, then drain into air.
Current ternary catalyzing unit, generally filled using cellular catalyst bracket inside it, plated on catalyst bracket
It is formed with noble metal catalyst；Because tail gas contained impurity in itself, and the complex compound generated in chemical reaction process are easier to
Accumulated on cellular catalyst bracket, therefore the time one is grown, and more blocking, sintering will be formed inside ternary catalyzing unit
Region, and block the order of severity and gradually successively decrease from catalyst converter air inlet to gas outlet；This has resulted in the blocking of catalyst converter leading portion
Seriously, back segment situation of good performance, underuse catalyst converter each several part and just scrapped, cause larger waste.
The content of the invention
In view of the above-mentioned problems, it is an object of the invention to provide a kind of durable type ternary catalyzing unit, the three-element catalytic utensil
There is longer service life.
Technical scheme is used by the present invention realizes technical purpose：The durable type ternary catalyzing unit is including shell and outside
Honeycombed catalyst support inside shell；Plating is formed with three-way catalyst on the catalyst bracket；The shell is in box-like, the institute of circle
It is in the nahlock shape to match with shell inner cavity to state catalyst bracket, and catalyst bracket can be in shell around shell and catalyst branch
The common axis rotation of frame；Air inlet and gas outlet are connected in the circumferential wall of the axis both sides of the shell.
Preferably, a side plane of the catalyst bracket is fixed with circular flat board, the circular flat board exposes institute
The inside of shell is stated, forms a rotatable side plane of the shell；Knob is formed with the circular flat board, can be from the shell
External hand rotate the catalyst bracket.Further, be formed with one week scale on the circumference of the circular flat board, it is described enter
Reference graduation is formed with gas port and/or gas outlet, to indicate the front hook of working as of the circular flat board, that is, the catalyst bracket
Work as front hook.
Preferably, the air inlet tangentially connects the circumferential wall of the shell, the air-flow in air inlet is set tangentially to enter
Enter enclosure；The gas outlet is rotated 180 ° around housing axis by the air inlet and obtained.Further, the catalyst
Between support is connected to two side planes of the shell by rotating shaft axle, the side plane and periphery of catalyst bracket with shell
The minim gap less than 1mm is left between wall, to reduce the spin friction of catalyst bracket.
The beneficial effects of the present invention are：At work, vehicle exhaust enters the durable type ternary catalyzing unit from air inlet
And discharged after passing through catalyst bracket from gas outlet；After long period, cellular catalyst bracket is close to the portion of air inlet
Divide and be blocked first, increase exhaust resistance, and then blockage is lighter for the part away from air inlet；Therefore, only need to be by described in
Catalyst bracket turns over an angle, will block heavier part and leaves air inlet, then remainder can participate in catalysis instead
Should while ensure good venting capability, so as to extend the service life of the ternary catalyzing unit.
Brief description of the drawings
Fig. 1 is the section schematic diagram of the embodiment one of this durable type ternary catalyzing unit.
Fig. 2 is the appearance schematic diagram of Fig. 1 embodiments.
Fig. 3 is the section schematic diagram of the embodiment two of this durable type ternary catalyzing unit.
Embodiment
The present invention is further described with reference to the accompanying drawings and examples：
Embodiment one：
In the embodiment one shown in Fig. 1, Fig. 2, the durable type ternary catalyzing unit includes the honeybee of shell 1 and enclosure
Nest shape catalyst bracket 2；Plating is formed with three-way catalyst on the catalyst bracket 2；The shell 1 is in box-like, the catalysis of circle
Agent support 2 is in the nahlock shape to match with shell inner cavity, and catalyst bracket 2 can be in shell around shell 1 and catalyst bracket 2
Common axis rotation；Air inlet 3 and gas outlet 4 are connected in the circumferential wall of the axis both sides of the shell 1.
In embodiment one, the air inlet 3, gas outlet 4 are facing each other；One side plane of the catalyst bracket 2
Circular flat board 11 is fixed with, the circular flat board 11 exposes the inside of the shell 1, and form the shell 1 one is rotatable
Side plane；Knob 5 is formed with the circular flat board 11, the catalyst bracket 2 can be rotated from the external hand of the shell 1.Institute
State and one week scale is formed with the circumference of circular flat board 11, reference graduation is formed with the air inlet 3 and gas outlet 4, to indicate
State the front hook of working as of circular flat board 11, that is, the catalyst bracket 2 works as front hook.
At work, vehicle exhaust is after air inlet 3 enters through catalyst bracket 2 to above-mentioned durable type ternary catalyzing unit
Discharged from gas outlet 4；After long period, cellular catalyst bracket 2 is being blocked first close to the part of air inlet 3, makes
Exhaust resistance increase, and then blockage is lighter for the part away from air inlet 3；Therefore, the catalyst bracket 2 need to only be turned over
One angle, heavier part will be blocked and leave air inlet 3, then remainder can ensure good while catalytic reaction is participated in
Good venting capability, so as to extend the service life of the ternary catalyzing unit.
Embodiment two：
In the embodiment two shown in Fig. 3, the air inlet 3 tangentially connects the circumferential wall of the shell 1, makes air inlet
Air-flow in 3 tangentially enters inside shell 1；The gas outlet 4 is rotated 180 ° around housing axis by the air inlet 3 and obtained.
Between the catalyst bracket 2 is connected to two side planes of the shell 1 by the axle of rotating shaft 20, the side plane of catalyst bracket 2
The minim gap less than 1mm is left between periphery and the inwall of shell 1, to reduce the spin friction of catalyst bracket 2.
For embodiment two, when the inside of catalyst bracket 2 is close to the Partial Blocking enhancing of air inlet 3, due to by air-flow
Thrust, 20 rotation around the shaft under airflow thrust effect of catalyst bracket 2 will be made, so that blocking serious part from turn
From air inlet 3, make the subparticipation catalytic reaction that blocking is lighter, be smoothly vented so as to ensure automatically, without manually adjusting.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
