The present invention relates to a catalytic reaction device. More specifically, the present invention relates to an apparatus having higher catalytic reaction efficiency and preventing loss of fluid in the course of the catalytic reaction.

In general, nitrogen oxides (NOx) is a generic term for compounds produced by the reaction of nitrogen and oxygen due to excessive supply of air in a high-temperature combustion facility. It is known as a direct causative agent. In particular, since internal combustion engines, such as automobiles using fossil fuels, inevitably generate nitrogen oxides, they are strictly controlling the amount of nitrogen oxides contained in exhaust gas through various regulations or regulations.

In particular, post-treatment techniques for nitrogen oxides are known as selective catalytic reduction (SCR), selective non-catalytic reduction (SNCR), and low-nox burner (LOW-NOX BURNER). In the case of the selective catalytic reduction method, nitrogen oxide is brought into contact with the catalyst to reduce it to nitrogen and water, and it shows a great difference in reduction efficiency depending on the composition, method, and surface area of the contact surface. In addition, the selective non-catalytic reduction method is a technique using only a reducing agent without a catalyst, and the low-nax burner method is a technique for controlling the combustion state in a heating furnace, but the selective catalytic reduction method is considered in consideration of the presence or absence of secondary pollution, removal efficiency, and operating cost. It is considered the most effective. This causes catalytic reaction more easily by maximizing the contact ratio through the first catalyst unit and the second catalyst unit in the process of moving the exhaust gas to zigzag as in the prior art document 1 (Republic of Korea Patent Publication No. 10-2015-0128255) Technology has been disclosed. However, in the case of the prior document 1, it is difficult to inject a large amount of fluid at a time because the catalytic reaction must occur sequentially, and when the fluid is added, the catalytic reaction is difficult to occur properly because the movement path is excessively long.

Here, the convex portion 203 is formed to protrude upward and downward from the upper and lower surfaces of the first catalyst portion 210d or the second catalyst portion 220d, and the concave portion 204 is the first catalyst portion 210d ) Or intaglio is formed on the upper and lower surfaces of the second catalyst unit 220d. In addition, a plurality of convex portions 203 and concave portions 204 are provided and alternately arranged alternately, and the convex portions 203 and concave portions 204 have various cross-sectional shapes such as irregularities, trapezoidal shapes, and the like. Can have Accordingly, the surface of the first catalytic portion 210d or the second catalytic portion 220d is formed with a step equal to the sum of the height of the convex portion 203 and the height of the concave portion 204, so that the surface of the checkerboard arrangement is formed. Have Through this, the reaction time of the fluid contacting the first catalyst unit 210d or the second catalyst unit 220d inside the body portion 100 may be increased to more easily derive a catalytic reaction.

Through a series of configurations of the present invention, a more robust support is possible through point contact or surface contact between the first catalyst unit 210 and the second catalyst unit 220, and the first catalyst unit 210 having a specific cross-sectional shape And by providing the second catalyst unit 220, it is possible to prevent damage to the first catalyst unit 210 and the second catalyst unit 220 between the movement of the fluid. In addition, through the body portion 100 according to the present invention, the frame thickness can be made thinner compared to the prior art, and the efficiency can be increased by increasing the catalyst performance.

The above-described preferred embodiments of the present invention are disclosed for the purpose of illustration, and those skilled in the art will appreciate various modifications, changes, and additions within the spirit and scope of the present invention. It should be regarded as belonging to the above claims.

If a person having ordinary knowledge in the technical field to which the present invention pertains, various substitutions, modifications and changes are possible without departing from the technical spirit of the present invention. It is not limited by.
