Abstract

The utility model is related to a kind of catalyst filter cores, and several inlet channels and several outlet passageways are formed in carrier.The carrier has the position of first end face and second end face in carrier between first, second end face to be distributed several holes.These outlet passageways separate whole inlet channels, so that inlet, outlet passage can only communicate with each other via hole.Each oxidation catalyst layer attachment carrier surrounds the wall surface of inlet channel, and each reducing catalyst layer attachment carrier surrounds the wall surface of outlet passageway.When filter core configuration is in exhaust emission system, make the inlet face of inlet channel to waste gas flow direction.The oxidation catalyst layer generates oxidation reaction to exhaust gas, and gas is reduced catalyst layer filter core and is reduced to innocuous gas after oxidation, the opposite quality for promoting environmental protection.

Description

Catalyst filter core

Technical field

The utility model is related to the field of purification of exhaust gas, particularly relate to a kind of catalyst filter core.

Background technology

Exhaust gas is the product after burning, is common in vapour (machine) vehicle or power plant, the boiler of factory, becomes the misfortune source of pollution air One of.Fine particle containing compounds such as substantial amounts of carbon, sulphur in exhaust gas, and ignition temperature is more high more is also easy to produce, it is right Air quality causes serious pollution.

Utility model content

The purpose of this utility model is to provide a kind of use redox construction, filter core is enable to purify in exhaust gas mostly The catalyst filter core of several harmful substance, the opposite quality for promoting environmental protection.

In order to achieve the above objectives, the filter core of the utility model includes：

Carrier has first end face, second end face and several holes, these holes are in carrier between first end face and second Position between end face；

Several inlet channels, these inlet channels are axially formed in carrier, and each inlet channel has entrance and closing Portion, the entrance is by the first end face of carrier, and the closure is adjacent to the second end face of carrier；

Several outlet passageways, these outlet passageways are axially formed in carrier and separate whole inlet channels, each Outlet passageway has outlet and closure, which is led to by the second end face of carrier, the closure adjacent to the first end face of carrier It crosses hole and uses gas passage and inlet channel intercommunication；

Multiple oxidation catalyst layers, each oxidation catalyst layer attachment carrier surround the wall surface of inlet channel, do not block hole but； And

Multiple reducing catalyst layers, each reducing catalyst layer attachment carrier surround the wall surface of outlet passageway, do not block hole but.

When filter core configuration is in exhaust emission system, allow the inlet face of inlet channel to waste gas flow direction, the oxidation catalyst layer Oxidation reaction is generated to exhaust gas, which restores again effect.

In this way, the catalyst filter core of the utility model, mostly has with oxidation, two catalyst layers of reduction to purify in exhaust gas Evil substance, the opposite quality for promoting environmental protection.

Specific embodiment

As shown in Figure 1, the filter core 10 has carrier 11, which forms several runners 14, and is surrounded in carrier 11 The wall surface of runner 14 arranges multiple oxidation catalyst layers and multiple reducing catalyst layers.

In the present embodiment, which is cylinder, possesses first end face 12 and second end face 13.The carrier 11 is to use violet The ceramic articles that green stone (Cordierite) makes, therefore position of the carrier 11 between first end face 12 and second end face 13, Mostly it is distributed several hole 11a (see Fig. 3).

In some embodiments, which can be gengon, for example cuboid.

In Fig. 2,3, the runner 14 distinguishes two groups according to flow direction：One group of inlet channel 15 and one group of outlet passageway 16.Wherein, these inlet channels 15 extend certain depth along the axis direction of carrier 11, and 15 2 end of inlet channel is defined For entrance 15a and closure 15b.Entrance 15a is by the first end face 12 of carrier 11, and closure 15b is adjacent to carrier 11 Second end face 13.

These outlet passageways 16 are also to extend certain depth along the axis direction of carrier 11, and by whole inlet channels 15 separate.Although each outlet passageway 16 has outlet 16a and closure 16b, orientation is totally different from inlet channel 15.It changes Sentence is talked about, and outlet 16a is by the second end face 13 of carrier 11, and closure 16b is adjacent to the first end face 12 of carrier 11.Cause This, which can only communicate with each other with inlet channel 15 through hole 11a.

In addition, the oxidation catalyst layer 20 attachment carrier 11 surrounds the wall surface of inlet channel 15, hole 11a is not blocked but.Institute The reducing catalyst layer 22 stated adheres to the wall surface that carrier 11 surrounds outlet passageway 16, does not block hole 11a equally.

In figure, which configures in exhaust emission system 30, such as exhaust pipe.In this way, the entrance of the inlet channel 15 15a faces waste gas flow direction 32, as outlet passageway 16 outlet 16a then against net airflow to 34.It puts it bluntly, exhaust gas is by filter core 10 It is filtered into clean gas outflow.

Above narration and explanation is only the explanation of the preferred embodiment of the utility model, for those skilled in the art When other modifications can be made according to more than claim and above-mentioned explanation, simply these modifications should be for this practicality newly The creation spirit of type and in the interest field of the utility model.
