The present invention relates to a catalytic converter for exhaust gas. According to the present invention, the catalytic converter for exhaust gas is a catalytic converter (10) for exhaust gas of an internal combustion engine and, especially, is an SCR exhaust gas catalytic converter. The catalytic converter for the exhaust gas includes: an interface module (11) having an inlet (14) for the exhaust gas to be purified and an outlet (15) for the purified exhaust gas; a conversion module (12) converting the exhaust gas to be purified; and at least one exhaust gas purifying module (13) located between the interface module (11) and the conversion module (12) and accommodating a catalyst (27), wherein the exhaust gas passes through the exhaust gas purifying module and flows to be purified. The interface module (11) includes: a radial direction outer flow path (16) coupled to the inlet (14), wherein the exhaust gas to be purified passes and flows; and a radial direction inner flow path (17) coupled to the outlet (15), wherein the exhaust gas to be purified passes and flows. The each exhaust gas purifying module (13) includes: a radial direction outer flow path (20) arranged with or connected to the radial direction outer flow path (16) of the interface module (11); and a radial direction inner flow path (21) arranged with or connected to the radial direction inner flow path (17) of the interface module (11). The catalyst (27) is located on the radial direction inner flow path (21) of the each exhaust gas purifying module (13). The conversion module (12) converts the flow from the radial direction outer flow path (20) of the exhaust gas purifying module (13) adjacent to the conversion module into the radial direction inner flow path (21) of the exhaust gas purifying module. |
