Description

[0001] CATALYST SUPPORT MODULE FOR MASS CATALYTIC REACTOR [0002]

The present invention relates to a catalyst support module for a large-capacity catalyst reactor, and more particularly, to a catalyst support module for a large-capacity catalyst reactor, which can be assembled in a large-capacity structure so as to be applicable to a large-capacity catalyst reactor, And more particularly, to a catalyst support module for a large-capacity catalyst reactor which can be manufactured at a lower cost.

Pollutants such as nitrogen oxides, sulfur oxides, carbon monoxide, hydrocarbons, etc. contained in the exhaust gas are a great threat to the human environment, and countries are also accelerating the development of technologies for enhancing or reducing the regulation of harmful emissions.

The automobile sector, which has the largest amount of emissions, has a direct impact on the on-the-ground environment in which human lives, and thus the demand for regulatory control is high and the treatment technology has been advanced from early on. On the other hand, regulations on ship's exhaust gas have been relatively recent, and IMO and advanced countries are actively preparing countermeasures.

In 1973, the International Maritime Organization (IMO) adopted the International Convention for the Prevention of Pollution from Ships (MARPOL) as an international Convention on the Prevention of Marine Pollution from Ships. In this case, the emissions of nitrogen oxides (NOx) from ship engines that reduce emissions by 20% from Annex II (Tier II), which starts in 2011, and 80% from Annex III (Tier Ⅲ) I am referring to the program. Therefore, in a large ship industry using a large-sized engine, researches on a large-capacity catalytic converter for purifying nitrogen oxides and the like contained in the exhaust gas are actively conducted.

In the field of NOx reduction in green ship exhaust gas treatment technology to respond to environmental regulations related to shipbuilding and marine industry of International Maritime Organization, selective catalytic reduction (SCR) system with proven performance, safety and economical efficiency Is getting popular.

The SCR system includes a reactor equipped with a honeycomb-structured catalyst carrier. The catalyst carrier induces exhaust gas containing NOx and ammonia (NH 3 ) to produce nitrogen and water through a reduction reaction. As a material of the catalyst carrier, a ceramic extruded material which is easy to mass-produce at low cost has been devised, but the use of a metal carrier which can be manufactured with a thin thickness and has excellent mechanical properties is also increasing.

Unlike an automobile, a large-sized engine such as a ship or a plant sharply increases exhaust gas emissions, so that the size of a selective catalytic reduction system also increases, and a larger-sized carrier is required. In terms of manufacturing, the integrated catalyst carrier having a large size by merely increasing the size has a problem in manufacturability such as a lack of facilities for producing the same, and coating of the catalyst is also difficult.

In order to solve this problem, a method of manufacturing a catalyst carrier in a module form and assembling the catalyst carrier has been proposed. Such modular production and assembly structures are important not only for production but also for maintenance and replacement of the carrier.

Korean Patent Laid-Open Publication No. 10-2012-0117426 (Patent Document 1) discloses a structure in which a large-capacity catalyst carrier is produced in the form of a unit catalyst carrier block and assembled, or a structure in which an assembly member is fastened between adjacent unit catalyst carrier blocks It has a lot of fastening points and a complicated structure.

In addition, in the unit catalyst carrier block of Patent Document 1, a cell-formed body in which a plurality of hollow cells are formed by a wave plate / flat plate assembly fabricated from a flat plate and a wave plate made of a thin metal plate coated with a catalyst on the surface corresponds to the shape of the cell- And a support for receiving and inserting the cell-formed body as a polygonal structure.

Furthermore, conventional metal carriers implemented using metal plate-like metal plate wafers coated with a catalyst on the surface and wafers / plate assemblies made from flat plates are used for brazing, welding, soldering, And a diffusion / bonding joining method such as diffusion bonding, the productivity is low, and it is difficult to secure price competitiveness.

When the metal carrier module used in a catalytic reactor for an automobile or a home appliance is laminated and fixed without bonding a corrugated plate to a flat plate, it is difficult to apply because it resonates with vibration generated in an engine or a motor in operation, In the case of large ships or power generation facilities, such noise is not a problem.

Korean Patent Laid-Open Publication No. 10-2014-0064358 (Patent Document 2) discloses a winding type metal carrier for forming a large-capacity catalyst carrier, which is wound around one axis so that a flat plate and a corrugated plate are alternately arranged, The flat plate and the corrugated plate include a polygonal winding section formed to have a polygonal section for each winding and a core section inserted into the center of the polygonal winding section and formed in a wound form.

The wrapping-type metal carrier of Patent Document 2 can reduce the weight of the carrier, reduce the welding cost, and improve the workability by omitting the outer can or the housing and fixing the flat plate and the corrugated plate in a polygonal winding state.

However, the metal carrier of Patent Document 2 has a winding type structure, and since the core portion is separately fabricated and assembled, there is a limit to improvement in productivity.

On the other hand, the exhaust gas discharged from a large-scale plant such as an automobile, a household appliance, a power plant or an incinerator contains a pollutant such as sulfur oxides, carbon monoxide and hydrocarbons in addition to nitrogen oxides.

The large-scale catalytic reactor can be applied to a selective catalytic reduction (SCR) system for reducing nitrogen oxides (NOx) according to a catalyst coated on a metal carrier, and can be applied to Pt / Rh, Pd / Rh or Pt / Pd / (CO), nitrogen oxides (NOx) and hydrocarbons (HC) based compounds contained in the exhaust gas in an automobile when using a three way catalyst, can be applied to an exhaust gas catalytic converter for removing these compounds simultaneously And can be applied to a catalytic reactor that is used in a reformer of a fuel cell to induce a chemical reaction of hydrocarbons.
