CATALYTIC CONVERTER AND METHOD FOR ITS MANUFACTURE Russian patent published in 2021 - IPC F01N3/28 

FIELD: chemical technology.

SUBSTANCE: group of the invention relates to catalytic converters of exhaust gases of internal combustion engines. The catalytic converter contains a housing, transition pieces: an inlet with a flange and an outlet pipes, catalytic blocks located inside the housing. Moreover, the housing, inlet and outlet pipes have rectangular cross-sections. Transition pipes of variable rectangular cross-section are located between the housing and the inlet and outlet pipes. The catalytic blocks are connected to each other by an integral connection by welding along the entire length of the combined circles, in the form of cylindrical rods. The rods are arranged vertically and parallel to each other in the holes of the two clips, protrude from both sides beyond these clips and are connected to them by an integral joint by welding along the circumference of their joint. In this case, a single cellular catalytic unit is formed, which is connected to the housing by welding with an integral sealed connection along the perimeter of the clips. A method for manufacturing the claimed catalytic reactor is also proposed.

EFFECT: when implementing the invention, an increase in reliability is provided, significant simplification of the structural elements of the device and reduction in energy costs during manufacture.
