Abstract
The catalyst fixing device (1) introduces the slurry into the channel of the catalyst carrier (2). The catalyst fixing device (1) has: a platform (4) with a setting frame (3) connected to the catalyst carrier (2); a sealing material (5) surrounding the catalyst carrier (2) 2) The connection part with the installation frame (3); the clamping parts (6) to (9), the clamping parts (6) to (9) exert force on the sealing material (5) in the direction of the catalyst carrier (2) ; and a catalyst supply part (10) that introduces a liquid (slurry) containing a catalyst component to the catalyst carrier (2). Connect the catalyst carrier (2) to the installation frame (3), and compress the sealing material (5) using the clamps (6) to (9). After compressing the sealing material (5) to seal the connection portion between the catalyst carrier (2) and the installation frame (3) in a water-tight manner, the slurry is introduced from the catalyst supply portion (10) into the channel of the catalyst carrier (2).
Description
technical field [0001] The present invention relates to a catalyst fixing device and a catalyst fixing method for supporting a catalyst component in channels of a catalyst carrier formed with a plurality of channels. Background technique [0002] A catalytic converter or the like is used as a purification device for decomposing and removing harmful components in exhaust gas discharged from an automobile engine. A catalytic converter is produced by coating a liquid (slurry) containing catalyst components such as platinum and palladium on a honeycomb carrier made of ceramics, heat-resistant alloy foil, or the like, for example. [0003] As a method of supporting a catalyst component in the channels of the catalyst carrier having a plurality of channels (passages) as described above, a method of introducing a slurry containing a catalyst component from the opening of the channel is known (for example, Patent Documents 1 to 3). [0004] However, in the step of introducing the s...
