Description

Ceramic carrier for purifying automobile exhaust

Technical Field

The utility model belongs to the ceramic equipment field, concretely relates to automobile exhaust purifies uses ceramic carrier.

Background

Automobile exhaust is exhaust gas generated when an automobile is used, is harmful to human health, and has great influence on the living environment of human beings, the automobile exhaust contains hundreds of different compounds, and main pollutants comprise solid suspended particles, carbon monoxide, carbon dioxide, hydrocarbons, oxynitride, sulfur oxide and the like. In order to reduce the pollution of the automobile exhaust, an exhaust purifier is required to be installed, a catalyst carrier of the exhaust purifier generally adopts a filtering ceramic carrier, a conventional filtering ceramic carrier is a cylinder provided with through-hole-shaped air holes, the air holes are through holes which are linearly and parallelly communicated, and in the using process, the contact time of the exhaust and a catalyst coating is short, and the exhaust purification is insufficient. Therefore, there is an urgent need for a ceramic carrier for purifying automobile exhaust gas, which can solve the existing problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims at prior art not enough, provide a ceramic carrier for automobile exhaust purifies, this ceramic carrier can improve the area of contact of tail gas and pore inner catalyst layer, guarantees that catalytic reaction fully goes on, improves automobile exhaust's purifying effect.

The utility model provides a following technical scheme:

the utility model provides a ceramic carrier for automobile exhaust purifies, includes the carrier body, the carrier body is cylindrically, the distribution has a plurality of tunnels that link up in the carrier body and arrange in order, a plurality of evenly distributed's of tunnel inner wall fixedly connected with baffle, the baffle runs through the length direction in tunnel, the baffle is sharp shape baffle, wave baffle or zigzag shape baffle.

Preferably, grooves are formed in two sides of the carrier body.

Preferably, the number of said separators in each of said channels is 3 or 6.

Preferably, the cross section of the duct has a shape of a regular hexagon, and the partition is perpendicular to the side wall of the duct.

Preferably, the plurality of cell channels at one end of the carrier body are connected with each other to form a honeycomb surface.

Preferably, the cross-section of the channel is circular in shape.

Preferably, the carrier body is zirconia toughened alumina ceramic.

The utility model has the advantages that:

the utility model discloses be equipped with evenly distributed's baffle in the pore of carrier body, this baffle is sharp linear shape baffle, wave baffle or zigzag-shaped baffle, the setting up of baffle makes the area increase of pore internal surface to can improve the area of contact of catalyst layer in tail gas and the pore, the speed that automobile exhaust's speed more helps slowing down in the setting up of wave baffle or zigzag-shaped baffle in addition, increase the contact time of tail gas and catalyst layer, guarantee that catalytic reaction fully goes on, improve the purifying effect of tail gas.

Detailed Description

As shown in fig. 1 to 5, a ceramic carrier for purifying automobile exhaust comprises a carrier body 1, wherein the carrier body 1 is zirconia toughened alumina ceramic, and the ceramic has good corrosion resistance, breaking strength and fracture toughness. The carrier body 1 is cylindrical, and grooves 4 are formed in two sides of the carrier body 1, so that the ceramic carrier is convenient to mount and use. A plurality of pore canals 2 which run through the carrier body 1 and are orderly arranged are distributed in the carrier body 1, a plurality of partition boards 3 which are evenly distributed are fixedly connected with the inner wall of each pore canal 2, the partition boards 3 run through the length direction of the pore canals 2, and the number of the partition boards 3 in each pore canal 2 is 3 or 6. The separator 3 is a straight separator as shown in fig. 2, or the separator 3 is a wavy separator as shown in fig. 4, or the separator 3 is a zigzag separator as shown in fig. 5.

As shown in fig. 1, the cross-section of the cell channels 2 is in the shape of a regular hexagon, the partition walls 2 being perpendicular to the side walls of the cell channels 2. And a plurality of cell channels 2 at one end of the carrier body 1 are connected with each other to form a honeycomb surface. As shown in fig. 5, the cross-section of the porthole 2 is alternatively circular in shape.

This embodiment is equipped with evenly distributed's baffle 3 in carrier body 1's pore 2, this baffle 3 is sharp form baffle, wave baffle or zigzag-shaped baffle, the area increase of pore internal surface is made in the setting of baffle 3 to can improve the area of contact of tail gas and pore interior catalyst layer, the speed that automobile exhaust's speed more helps slowing down in the setting of wave baffle or zigzag-shaped baffle in addition, increase the contact time of tail gas and catalyst layer, guarantee that catalytic reaction fully goes on, improve the purifying effect of tail gas.
