Description

Technical Field

[0001] This utility model relates to the field of loading auxiliary equipment technology, and in particular to a fixed bed catalyst loading auxiliary device. Background Technology

[0002] During fixed-bed catalyst loading, auxiliary packing materials such as ceramic items, thermometer probes, positioners, and wire mesh are typically added to different bed layers. Due to the depth of the reactor, catalysts and ceramic balls added from the top are prone to breakage as they fall to the bottom. In actual loading, catalysts and ceramic items easily fall into the outlet pipeline, potentially clogging the entire system. Furthermore, because the reactor is deep and opaque, the exact location of added catalysts or ceramic balls is difficult to determine, leading to an inability to ascertain the catalyst loading position. This presents significant challenges for comparative experiments requiring perfectly consistent loading. Utility Model Content
