Description
Technical field
The utility model relates to a kind of field of environment protection equipment more particularly to a kind of exhaust purifiers.
Background technique
Ternary catalyzing unit is mounted in most important outer purifier in automobile exhaust system, it can be by vehicle exhaust
The evil gas of discharge is changed into harmless carbon dioxide, water and nitrogen by oxidation and reduction.Since this catalyst converter can
Innocuous substance is converted by three kinds of main harmful substances in exhaust gas simultaneously, therefore claims ternary.Due to three way catalytic conversion under room temperature
Device does not have catalytic capability, and catalyst, which must be heated to certain temperature just, has the ability of oxidation or reduction.So we give
A kind of heatable exhaust purifier out.
Utility model content
The purpose of this utility model is to provide a kind of exhaust purifiers, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the utility model provides the following technical solutions：
A kind of exhaust purifier, including shell, air inlet, gas outlet, flange, control solenoid valve, heating tungsten wire, temperature biography
Sensor, three-element catalytic honeycomb bracket, the housing forward end is integrally formed with air inlet, and housing rear end is integrally formed with outlet
Mouthful, integrally formed with flange, the housing forward end is interior to be equipped with heating tungsten wire by cross brace, described for the air inlet front end
Temperature sensor is equally equipped with by cross brace in heating tungsten wire, the case top front end is equipped with control battery valve,
The control battery valve is electrically connected temperature sensor, is equipped with three-element catalytic honeycomb bracket in the housing rear end.
Preferably：When the temperature for receiving temperature sensor detection when control battery valve reaches 250 °, control heating
Tungsten wire work, the exhaust purifier are threaded on air vent of automobile engine by flange, gas outlet rear end spiral shell
Line is connected on muffler.
The utility model has the beneficial effects that：The utility model structure is simple, and design rationally, passes through temperature sensor and control
Battery valve processed optimizes the effect of three-element catalytic to the tail gas heating of low temperature.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model exhaust purifier；
Fig. 2 is the cross-sectional view of the utility model exhaust purifier；
Fig. 3 is the cross-sectional view of the utility model exhaust purifier.
In figure：1, shell, 2, air inlet, 3, gas outlet, 4, flange, 5, control solenoid valve, 6, heating tungsten wire, 7, temperature biography
Sensor, 8, three-element catalytic honeycomb bracket.
Specific embodiment
The utility model is further elaborated in the following with reference to the drawings and specific embodiments：
As shown in Figure 1-3, a kind of exhaust purifier, including shell 1, air inlet 2, gas outlet 3, flange 4, control solenoid valve
5, tungsten wire 6, temperature sensor 7, three-element catalytic honeycomb bracket 8 are heated, 1 front end of shell is integrally formed with air inlet 2, and shell
For 1 rear end of body integrally formed with gas outlet 3,2 front end of air inlet passes through ten in 1 front end of shell integrally formed with flange 4
Word bracket is equipped with heating tungsten wire 6, is equally equipped with temperature sensor 7, the shell by cross brace in the heating tungsten wire 6
1 top nose of body, which is equipped with, controls battery valve 5, the electrical connection of control battery valve 5 temperature sensor 7, in 1 rear end of shell
Three-element catalytic honeycomb bracket 8 is installed.The temperature for receiving the detection of temperature sensor 7 when control battery valve 5 reaches 250 °
When, control heating tungsten wire 6 works, and the exhaust purifier is threaded on air vent of automobile engine by flange 4, described
3 rear end of gas outlet is threaded on muffler.
The utility model application method：Exhaust purifier nose threads are connected to engine by the screw hole on flange 4
Exhaust outlet, gas outlet 3 are threaded in muffler front end, the temperature when vehicle exhaust reaches 1 Inner Front End of shell by air inlet 2
Sensor 7 can detect exhaust temperature, and when exhaust temperature is not up to 250 °, control battery valve 5 can open the switch of heating tungsten wire 6
Make its work, the tail gas of process can then be heated and three-element catalytic better effect is being made by three-element catalytic honeycomb bracket 8.
It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and
And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms
Type.Therefore, the same variation in all respects, the embodiments should be taken as exemplary, therefore in equivalency range
All include in the scope of the utility model.
