Description

The catalyst carrier of outlet pipe

Technical field:

The utility model relates to a kind of catalyst carrier of outlet pipe, particularly at the simple type catalyst carrier of the less assembling aperture design of the outlet pipe of 15～30mm.

Prior art:

Heal strict waste gas emission standard in order to cater to, the dealer all can group establish catalyst carrier in the outlet pipe of engine or anechoic chamber, in order to content of harmful in the purifying exhaust air, makes to be disposed to extraneous waste gas and to be unlikely to influence air quality.

And knowing, comprise automobile, locomotive or other starts the aperture of the engine exhaust pipes of facility, is to decide according to engine exhaust amount size.The locomotive engine that air displacement is less or the engine of other little facility, the aperture of its outlet pipe is also less, and the smaller aperture due scope of 15～30mm of leveling off to is very arranged.Group is established catalyst carrier in the outlet pipe of this small aperture, must consider in the carrier whether the passage that can supply waste gas to pass through is enough smooth and easy, and can supply problems such as whether enough the area of catalyst coating in the carrier.

Existing catalyst carrier can be divided into honey comb like catalyst carrier a kind of tubular and another kind of haply.

Above-mentioned tubular carrier is coated with catalyst on its tubular inwall.This kind carrier extremely is fit to be installed in 15～30mm pore diameter range outlet pipe.Yet, can be very limited in this kind of tubular carrier for the inner wall area of catalyst coating, cause catalyst coating quantity not sufficient easily and force the ability of purifying exhaust air to be limited to, be difficult to meet and heal strict air environmental protection standard.

Above-mentioned honeycomb carrier is to utilize a metal plate and another metal wave plate to fit mutually to reel to form, can dull and stereotyped or and the wave plate on the coating catalyst.Yet this kind of carrier also is not suitable for being organized in the outlet pipe that is located at above-mentioned 15～30mm pore diameter range, easily makes to form excessive back pressure in the outlet pipe, influences engine performance.

From the above, lack a kind of less outlet pipe assembling aperture (catalyst carrier manufacturing technology of 15～30mm) that is applicable on the market in fact.

The model utility content:

The purpose of this utility model is to provide a kind of catalyst carrier that is applicable to 15～30mm outlet pipe aperture, can promote the ability that catalyst is imitated harmful exhaust in the purifying exhaust gas pipe when the locomotive engine cold start-up.

In order to achieve the above object, adopt following technological scheme: a kind of catalyst carrier of outlet pipe, to be located in the outlet pipe of engine connection, the outlet pipe proximal end plants in an anechoic chamber, and the aperture of described outlet pipe is between 15 ~ 30mm;

This catalyst carrier includes the tinsel that a section presents arc at least, is coated with catalyst on the tinsel, and assembly welding has joint on the tinsel, and tinsel directly is welded in the outlet pipe, and have around the tinsel in the outlet pipe make that waste gas passes through vent.

The catalyst carrier of outlet pipe as mentioned above, wherein this joint assembly welding is between tinsel and outlet pipe inwall.

The catalyst carrier of outlet pipe as mentioned above, wherein this linking department is located on the ring-type connecting base, and this connecting base with the tinsel assembly welding in outlet pipe.

The catalyst carrier of outlet pipe as mentioned above, wherein each tinsel weldering is put layout and is become the concentric circle form that is spaced apart, and has central channel between each tinsel and adjacent with vent.

The catalyst carrier of outlet pipe as mentioned above, wherein weldering is put layout and is become the non-concentric circle form that is spaced apart between each tinsel.

The catalyst carrier of outlet pipe as mentioned above, wherein this tinsel is provided with plural mesh.

The technical characterstic that the utility model adopts is as follows:

(1) present the carrier of the tinsel of arc as catalyst with at least one section, this tinsel has and is easy to punch die and makes and be easy to the advantage of assembly welding in the outlet pipe of smaller aperture due.

(2) assembly welding has joint on this tinsel, the metal horse can be held on the inwall in the less assembling of outlet pipe aperture of 15～30mm, impel tinsel and outlet pipe inwall between form vent, water conservancy diversion toxic emission smoothly.

(3) this tinsel is provided with plural mesh, helps increasing the touch opportunity of waste gas and catalyst.

(4) tinsel that is coated with catalyst can adopt plural number only, and interval group is welded in this outlet pipe, so that promote the reaction efficiency of catalytic control waste gas.

Embodiment:

First see shown in Figure 1ly, an engine 2 is shown connects an outlet pipe 3, these outlet pipe 3 proximal ends plant in an anechoic chamber 4, and organize in the outlet pipe 3 of aperture between 15～30mm of engine 2 and 4 of anechoic chambers and establish a catalyst carrier 1, wherein:

This catalyst carrier 1 includes the tinsel 12 that a section presents arc at least, on each tinsel 12 all assembly welding joint 13 is arranged, make tinsel 12 can directly be welded in the aperture on 3 inwalls of the outlet pipe between 15～30mm, and make outlet pipe 3 interior tinsels 12 form the vent 14 (as shown in Figure 2) of waste gas all around.

In addition, on the implementation in order to strengthen joint 13 with the soundness of tinsel 12 assembly weldings in outlet pipe 3, above-mentioned each joint 13 can be formed at (shown in Fig. 3,4) on the ring-type connecting base 11 so that utilize connecting base 11 with tinsel 12 assembly weldings in outlet pipe 3.

Above-mentioned tinsel 12 has and is easy to punch die and makes and be easy to assembly welding advantage the outlet pipe 3 of smaller aperture due in, therefore can promote to assemble and the convenience during welding procedure, promotes tinsel 12 simultaneously by the durability behind the assembly welding.

Direct coating catalyst on the above-mentioned tinsel 12, or on tinsel 12, offer the plural mesh 121 (as shown in Figure 3) that spreads all over coating catalyst then, impel in the outlet pipe 3 of the less exhaust caliber of tool only also catalyst carrier 1 to be set easily, to promote the usefulness of purifying exhaust air.

Above-mentioned tinsel 12 can be put layout by weldering and become Fig. 4 and the concentric circle shown in Figure 5 form that is spaced apart, and makes to have central passage 15 between each tinsel 12 and adjacent with vent 14 smoothness so that exhaust gas routing to be provided.Above-mentioned tinsel 12 also can be put layout by weldering and become the non-concentric circle shown in Figure 6 form that is spaced apart.
