Abstract
The utility model relates to a novel ceramic catalyst carrier used in a catalytic chamber of a purification silencer for automobiles and motorcycles. The utility model is characterized in that the novel ceramic catalyst carrier is an activated alumina ceramic irregular ball body with multiple micropores. The ball body is provided with a through hole. Both ends of the through hole are respectively provided with 2-8 equally divided slots rotating along an axial line to equally divide a circumference. The utility model is prominently characterized in that the utility model can ventilate from multiple positions. The utility model collected in a catalytic chamber of a purification silencer can display the special function of the utility model. As the ceramic ball body is provided with multiple micropores, the utility model can display all the advantages of rough surface, great increase of specific surfaces, low containing heat, vibration resistance, wear resistance, strong self-cleaning property, air blocking eradication, etc. The utility model can be firmly combined with noble metals and a plurality of non-noble metals, such as rare earth. The ability to bear sharp temperature difference is strong, and the service life of the utility model reaches more than one hundred thousand kilometers.
Description
The utility model relates to the carrier structure of catalyzer, particularly a kind of new ceramics carrier that is used for automobile, motor purifying silencing apparatus catalyst chamber catalyzer.
At present, the catalyst carrier that is used for automobile, motorcycle tail gas cleaning both at home and abroad is of a great variety, differ from one another, but multiple service index of ubiquity and economic indicator such as is difficult to take into account at problem.China is along with the continuous development of environmental protection cause, and the blowdown problem of Motor Vehicle has been subjected to the attention of height, if it is costly to buy external catalytic cracker, and be difficult to homemade multiple model Engine Matching good.
The utility model purpose is to provide the resistance of a kind of aeration resistance much smaller than common silencing apparatus, has bigger surface area, holds that heat is low, vibration resistance is strong, wear resistance good, can be with multiple non-noble metal strong bonded such as precious metal and rare earth, bear the vehicle tai-gas clean-up catalyst new ceramics carrier of advantages such as temperature difference great change ability is strong.
Above-mentioned purpose of the present utility model is to realize by such technological scheme, it is a kind of vehicle tai-gas clean-up catalyst new ceramics carrier, it is characterized in that: be activated alumina multi-microporous ceramic abnormity spheroid, spheroid has a through hole, and the two ends in hole respectively have 2-8 five equilibrium groove to divide equally circumference along the axis transposition.
Above-mentioned purpose of the present utility model is further specified by the embodiment that accompanying drawing provides.
Accompanying drawing 1 is a structure plan view of the present utility model;
Accompanying drawing 2 is a structure side view of the present utility model.
Referring to accompanying drawing: vehicle tai-gas clean-up catalyst new ceramics carrier among the figure is characterized in that: be activated alumina multi-microporous ceramic abnormity spheroid, spheroid has a through hole 1, and the two ends in hole respectively have 2-8 five equilibrium groove 2 to divide equally circumference along the axis transposition.Branch groove dislocation such as two groups are arranged up and down.The size of carrier becomes according to adapted silencing apparatus with it, and its span is: external diameter S is that 4-10 millimeter, aperture Φ are that five equilibrium groove 2-8, groove width a are respectively arranged is that 1-4 millimeter, groove depth b are the 1.5-4 millimeter for the two ends in 1-7 millimeter, hole.In the present embodiment, respectively there are four five equilibrium grooves at the two ends in hole.
The utility model carrier is designed to the above ventilation of octahedral, and it packs the gross weight of purifying muffler catalyst chamber into when closing the symbol standard volume, and aeration resistance is much smaller than the resistance of common silencing apparatus.Because there are the big and microporosity of roughness in the structure of carrier and surface, thereby can obtain bigger surface area; Simultaneously, it has, and to hold heat low, vibration resistance is strong, wear resistance good, can with multiple non-noble metal strong bonded such as precious metal and rare earth, bear advantages such as temperature difference great change ability is strong.Be easy to tissue and produce in batches, be easy to assembling, be easy to upgrade, be easy to mate rapidly with various motors.The utility model carrier is used in the EFI car purifying muffler, and tail gas can reach near-zero release, and can reach more than 100,000 kilometers working life.
