Description

Technical Field

[0001] This utility model relates to the field of cleaning technology for propane dehydrogenation catalyst regeneration systems, specifically a continuous carbon deposit cleaning device for propane dehydrogenation catalyst regeneration systems. Background Technology

[0002] The root cause of carbon buildup in propane dehydrogenation catalyst regeneration systems lies in the localized high temperatures and chemical environment changes during the regeneration process. During regeneration, if there is insufficient oxygen (especially in localized areas), the carbon buildup on the catalyst surface will burn and generate olefins, CO, and tar-like polymers. These gaseous products condense upon cooling during transport and eventually deposit on the inner wall of the exhaust pipe to form a sticky carbon layer.

[0003] Currently, most carbon deposit cleaning of exhaust pipes is done manually, but this method requires stopping the exhaust pipe, which is not very convenient.

[0004] Therefore, it is particularly important to design a continuous carbon deposit cleaning device for propane dehydrogenation catalyst regeneration system to overcome the above-mentioned technical defects and improve overall practicality. Utility Model Content
