Description

Unit catalyst carrier block and large-capacity catalyst carrier and catalytic converter using it {UNIT CATALYST SUPPORT BLOCK AND CATALYST SUPPORT OF MASS AND CATALYST CONVERTER USING THE SAME}

The present invention relates to a large-capacity catalyst carrier and a catalytic converter using the same, and more particularly, to a catalytic converter requiring a large-capacity exhaust gas treatment such as a large vessel or a plant or a large-scale food waste treatment apparatus employing a plurality of large-capacity internal combustion engines. The present invention relates to a unit catalyst carrier block having an assembly structure capable of easily assembling and increasing a number of unit catalyst carrier blocks by changing the unit catalyst carrier block into a shape that can be effectively assembled, and a large capacity catalyst carrier and a catalytic converter using the same. .

In general, automobiles and ships use fossil fuels such as gasoline and gasoline to generate power for driving. Due to its structural characteristics, exhaust gases harmful to the human body, such as carbon monoxide and nitrogen oxides, due to incomplete combustion of fuels, Therefore, various devices are provided in each part of the vehicle body in which harmful components are generated due to incomplete combustion of fuel, such as a combustion chamber in which fuel such as gasoline is combusted, an intake system in which air and fuel are mixed, and an exhaust system in which exhaust gas is discharged. Thus, the amount of generation of the exhaust gas is suppressed as much as possible.

Therefore, in order to remove harmful components of exhaust gas, a catalytic converter is attached between exhaust pipes of automobiles which exhaust the exhaust gas to the outside. The catalytic converter includes an oxidation catalyst for oxidizing carbon monoxide (CO) and hydrocarbons (HC) in exhaust gas and converting them into carbon dioxide (CO ₂ ) and water (H ₂ O), and nitrogen compound (NO _x ) to nitrogen (N ₂ ). Reducing catalysts are used to reduce the amount of the catalyst.In order to meet the requirements such as the temperature required for the reaction and the residence time of the exhaust gas, the catalyst carrier having a large effective area of the catalytic converter and a particulate catalyst adhered to the surface of the catalyst converter It is mounted in the housing.

On the other hand, the catalyst carrier has a honey comb structure having a rectangular or hexagonal cell structure, and is coated with a catalyst for causing harmful components of the exhaust gas to cause oxidation and reduction reactions.

Therefore, the exhaust gas flowing into the housing via the exhaust pipe catalyzes the catalyst coated on the catalyst carrier and proceeds to the outlet.

An example of a catalyst carrier having a honey comb structure is disclosed in Korean Patent No. 527970, which will be described with reference to FIGS. 1 and 2.

The catalyst carriers 1a and 1b constitute cells 4a and 4b which form a rectangular cell structure shown in FIG. 1 or a hexagonal cell structure shown in FIG. 2, and each of the cells 4a and 4b has a through portion ( 3a, 3b). A catalyst coating layer (eg, alumina (Al ₂ O ₃ ), etc.) containing a noble metal is coated between the cells 4a and 4b and the cell passage partition walls 2a and 2b. These catalyst carriers (1a, 1b) can perform a function by performing the oxidation or reduction reaction of the exhaust gas by the catalyst coated on the coating layer.

The catalyst carrier for automobiles has a cell structure having a circular ceramic integrated cell structure, which makes the coating layer uniform, and also increases the cell density by decreasing the vertical height between the cell lines, thereby contacting the catalyst carrier with the exhaust gas. It is proposed with the aim of improving the overall exhaust gas purification efficiency of the catalytic converter by ensuring sufficient conditions.

However, such a catalyst carrier for automobiles is manufactured by an extrusion process in which a ceramic raw material is supplied to an extruder, pushed out of a mold, and converted into a continuum having a honeycomb-shaped cross section, so that a large ship or a plant using a large number of large engines is used. There is a problem that is difficult to apply where a large-capacity catalytic reactor, such as.

In addition, a diesel particulate reduction device for extruding a high hardness material, for example, SiC, such as diesel particulate filter (DPF) for diesel engines, has a short and expensive lifespan for an extruded mold, and a large number of molds depending on the type of mass-produced products. There is a difficulty to possess.

In addition, the catalyst carrier disclosed in Korean Patent No. 527970 has a cylindrical shape regardless of the cell structure, and thus the catalyst carrier cannot be easily assembled with each other when integrated at a large capacity.

As described above, conventionally, in order to manufacture such a large-capacity catalyst carrier, a plurality of cylindrical unit catalyst carrier blocks having a ceramic structure are laminated to attempt to increase the capacity, but there is a problem of difficulty in manufacturing.

On the other hand, when the catalyst carrier is made of a metal, when the diameter is generally 30 cm or less, the production is easy, but it is difficult to produce a larger than this.

In particular, the International Maritime Organization (IMO) adopted the International Convention for the Prevention of Pollution from Ships (MAPOL) in 1973 as an international convention on the prevention of marine pollution from ships. It was. Here, the regulation of ship engine emissions nitrogen oxides is reduced by 20% in Annex II (Tier II) starting from 2011 and 80% in Annex III (Tier III) starting in 2016. The program is mentioned. For reference, the International Maritime Organization (IMO) is a United Nations specialized organization established for the international unification of ship routes, traffic rules, and port facilities. For this reason, studies on large-capacity catalytic converters for purifying nitrogen oxides and the like contained in exhaust gases have been actively conducted in large ship industries using large engines.

Therefore, such a catalytic converter requires a structure that can be manufactured and provided in a large capacity from a small capacity structure so as to process a large amount of exhaust gas such as a large vessel or a plant or a large amount of food treatment apparatus employing a plurality of large capacity internal combustion engines. .
