Abstract
The utility model discloses a three way catalyst converter comprising a shell whereof one end is connected to a upper channel from where tail gas is discharged, wherein the other end of the shell is connected to a lower channel, the inner wall of the shell being provided with a pad which surrounds a three way catalyst converter core, the upper channel being provided with a upstream sensor which senses composition and concentration of the tail gas and gives feedback to a computer, the computer being employed for controlling the three way catalyst converter for conversion of the tail gas, the lower channel being provided with a downstream sensor. In case the downstream sensor does not finish conversion, conversion in next procedure can be carried on until standard of environmental protection is reached. The thickness of the pad is 7mm, which can guarantee efficient exhaust temperature. The utility model has two sensors, which permits a better conversion of tail gas. The utility model also has the advantages of simple structure and high popularization in market.
Description
Technical field:
The utility model relates to a kind of ternary catalyzing unit, mainly applies to the processing of motor vehicle exhaust emission.
Background technique:
The effect of ternary catalyzing unit is exactly that the harmful gas that automobile is got rid of is converted into innocuous gas.Main harmful gas in the vehicle exhaust has carbon monoxide (CO), oxynitrides (NO), hydrocarbon (HC).Three-element catalytic utilizes some chemical agents exactly, carries out a series of chemical reaction with harmful gas in the tail gas, makes it be converted to harmless gas.If ternary catalyzing unit has been broken, just lost the function of conversion certainly, harmful tail gas will directly be discharged in the atmosphere, cause atmospheric pollution, general automobile is not provided with sensor or only is provided with a upstream sensor, causes the pollution to atmosphere easily, and the liner of sensor is also thinner.
Summary of the invention:
The purpose of this utility model is in order to overcome above deficiency, and a kind of simple in structure, a kind of ternary catalyzing unit that cost is low is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of ternary catalyzing unit; comprise housing; described housing one end is connected with upper channel; tail gas is discharged from upper channel; the described housing the other end is connected with lower channel; on the described inner walls liner is installed; described liner surrounds the ternary catalyzing unit core; on the described upper channel upstream sensor is installed; the composition and the concentration of upstream sensor induction tail gas; feedback to the computer; computer is controlled the conversion that the ternary catalyzing unit core carries out tail gas again, on the described lower channel downstream sensor is installed, and does not finish if the downstream sensor induction not transform; can proceed the conversion of next process, finally reach the standard of environmental protection.Described liner thickness is 7mm, can well guarantee effective delivery temperature.
The utlity model has following advantage: have two sensors, can well finish the conversion of tail gas, the thickness of liner is 7mm, can well guarantee effective delivery temperature, and structure is also very simple, is beneficial to the popularization in market.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Number in the figure: 1-housing, 2-upper channel, 3-lower channel, 4-liner, 5-ternary catalyzing unit core, 6-upstream sensor, 7-downstream sensor.
Embodiment:
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
Show a kind of ternary catalyzing unit of the utility model as Fig. 1; comprise housing 1; described housing 1 one ends are connected with upper channel 2; tail gas is discharged from upper channel 2; described housing 1 the other end is connected with lower channel 3; on described housing 1 inwall liner 4 is installed; described liner 4 surrounds ternary catalyzing unit core 5; upstream sensor 6 is installed on the described upper channel; the composition and the concentration of upstream sensor 6 induction tail gas; feedback to the computer; computer is controlled ternary catalyzing unit core 5 again and is carried out the conversion of tail gas, and downstream sensor 7 is installed on the described lower channel, if downstream sensor 7 inductions not transform does not finish; can proceed the conversion of next process, finally reach the standard of environmental protection.Described liner 4 thickness are 7mm, can well guarantee effective delivery temperature.The utlity model has and have two sensors, can well finish the conversion of tail gas, the thickness of liner 4 is 7mm, can well guarantee effective delivery temperature, and structure is also very simple, is beneficial to the advantages such as popularization in market.
