Problems solved by technology

The design space is therefore limited: on the one hand (especially in the case of subsequent retrofitting of the SCR reactor) due to site constraints, and on the other hand due to economic considerations

Embodiment Construction

[0011] The per se conventional configuration of the parallelepipedal catalytic conversion reactor 1 is determined in that the exhaust gas flow S flows from the inlet of the catalytic conversion module 2 within the catalytic converter module 2 without a diversion of the (main) flow direction caused by the catalyst. Side 2 ′ flows through channel 4 of catalytic converter element 3 to outlet side 2 ″ of catalytic converter module 2 .

[0012] In the configuration of the catalytic conversion reactor 1 shown in the drawing according to the invention, unlike conventional practice, the catalytic conversion module 2 configured as a parallelepiped with respect to the inlet side 2' and / or the outlet side 2" or the flow The direction is reorientated in the catalytic conversion reactor 1. Accordingly, the flow through the catalytic converter element 3 is in a direction deviating from the flow direction on the inlet side and / or outlet side, for example at an inclination of 60°. Via the cata...

Abstract

The invention relates to a catalytic conversion reactor (1) having an insert consisting of a catalytic conversion module (2), wherein the sum of the inflow inlet areas of the catalytic conversion elements (3) is greater than the catalytic conversion reaction The flow inlet area of ​​the reactor (1), where the area on the side of the catalytic conversion element facing the main flow direction (S) is defined as the inflow inlet area of ​​the catalytic conversion element (3), where, in the catalytic conversion reactor (1) A plurality of catalytic conversion elements (3) are provided, the catalytic conversion elements are placed in a catalytic conversion module (2), and the catalytic conversion module (2) is positioned obliquely in the catalytic conversion reactor (1) such that The exhaust gas flows through the catalytic conversion element (3) located in the catalytic conversion module in two alternating directions deviating from the flow direction on the inlet side and / or the outlet side.

Description

technical field [0001] The invention relates to a catalytic converter reactor with an insert consisting of catalytic converter modules. Background technique [0002] SCR catalysts constitute the state of the art for the removal of nitrogen from exhaust gases. This makes an important contribution to reducing ozone, acid rain and the greenhouse effect close to the ground. This technology is used in thermal power plants and waste incineration equipment as well as internal combustion engines and many industrial fields. [0003] In addition to the reduction of nitrogen oxides (nitrogen), catalysts are also used, for example, for the reduction of dioxins and furans, which is already implemented as a technical standard especially in waste incineration plants. [0004] Catalytic converter elements are provided, for example, in the form of homogeneously extruded honeycomb bodies or in the form of carrier materials which are provided with a catalytic layer on their surface and are r...
