Description
Technical field
The utility model relates to automobile environment-protection product technical field, particularly a kind of three-way catalytic converter.
Background technique
Three-way catalytic converter, is mounted in most important outer purifier in automobile exhaust system, and the harmful gas such as CO, HC and NOx that it can be discharged vehicle exhaust changes harmless carbon dioxide, water and nitrogen into by oxidation and reduction.In the time that the vehicle exhaust of high temperature passes through purification plant, purifying agent in three-way catalytic converter will strengthen the activity of CO, HC and tri-kinds of gases of NOx, impel it to carry out certain oxidation-reduction chemical reaction, wherein CO is at high temperature oxidized into colourless, nontoxic carbon dioxide; HC compound is at high temperature oxidized to water (H20) and carbon dioxide; NOx is reduced into nitrogen and oxygen, and three kinds of harmful gases become innocuous gas, and vehicle exhaust is purified.
Wherein, purifying agent carrier and purifying agent in three-way catalytic converter are core components, loss is larger, the three-way catalytic converter of prior art cannot be changed, once purifying agent carrier and purifying agent loss, just must be by three-way catalytic converter integral replacing, cost is larger, three-way catalytic converter in normal operation, because oxidation reaction has produced a large amount of reaction heat, must ensure the refractoriness of whole three-way catalytic converter.
Model utility content
The purpose of this utility model is to overcome the shortcoming of prior art, provides that a kind of easy accessibility, tightness are good, long service life and the low three-way catalytic converter of user cost.
The purpose of this utility model is achieved through the following technical solutions: a kind of three-way catalytic converter, it comprises suction tude, steam outlet pipe and converter body, suction tude and steam outlet pipe are arranged at the two ends of converter body, the outboard end of suction tude and steam outlet pipe is respectively arranged with adpting flange, described converter body comprises upper shell, lower shell body and netted dividing plate, upper shell and lower shell body are hinged and connected, and edge is provided with mounting plate, mounting plate equal intervals is provided with multiple mounting holes, and by bolt, upper shell and lower shell body are locked together, netted dividing plate is arranged at converter body interior.
Described upper shell and lower shell body are double-deck stainless sheet metal structure, and are provided with liner between double-deck interlayer.
Between described upper shell and lower shell body, be also provided with rubber washer.
Described upper shell and lower shell body madial wall are provided with fire protection layer.
Described netted dividing plate is equidistantly provided with 3.
The utlity model has following advantage:
1, the three-way catalytic converter of the utility model structure, converter body is hinged upper shell and lower shell body, is bolted, easy disassembly, is convenient to change inner purifying agent carrier.
2, between upper shell and lower shell body, be provided with rubber washer and ensure the tightness of whole housing.
3, housing is double-deck stainless sheet metal structure, is provided with asbestos fiber felt in interlayer, and the madial wall of housing is provided with fire protection layer, increases the heat resistance of housing, prevents that housing is overheated, extends the working life of housing.
4, netted dividing plate is set in converter body, netted dividing plate is equidistantly provided with 3, promotes the effect of air purification, and while changing netted dividing plate, without whole replacings, the replaceable netted dividing plate near suction tude one side, reduces user cost.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1-upper shell, 2-lower shell body, 3-suction tude, 4-steam outlet pipe, 5-adpting flange, 6-mounting plate, 7-mounting hole, the netted dividing plate of 8-.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, a kind of three-way catalytic converter, it comprises suction tude 3, steam outlet pipe 4 and converter body, suction tude 3 and steam outlet pipe 4 are arranged at the two ends of converter body, the outboard end of suction tude 3 and steam outlet pipe 4 is respectively arranged with adpting flange 5, described converter body comprises upper shell 1, lower shell body 2 and netted dividing plate 8, upper shell 1 is hinged and connected with lower shell body 2, and edge is provided with mounting plate 6, mounting plate 6 equal intervals are provided with multiple mounting holes 7, and by bolt, upper shell 1 and lower shell body 2 are locked together, netted dividing plate 8 is arranged at converter body interior.
Described upper shell 1 and lower shell body 2 are double-deck stainless sheet metal structure, and are provided with liner between double-deck interlayer, and liner is asbestos fiber felt, upper shell 1 and lower shell body 2 madial walls are provided with fire protection layer, the heat resistance that increases housing, prevents that housing is overheated, extends the working life of housing.
Between described upper shell 1 and lower shell body 2, be also provided with rubber washer, ensure the tightness of whole housing.
Described netted dividing plate 8 is equidistantly provided with 3.
While changing netted dividing plate 8, upper shell 1 is opened, without netted dividing plate 8 is all changed, only need to change the netted dividing plate 8 near suction tude 3 one sides, will be left to such an extent that 2 netted dividing plates 8 are pulled down, move forward one, new netted dividing plate 8 is arranged on finally, has reduced user cost.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
