Pulsed Jet Self Cleaning System
Pulsed jet cleaning is a process developed by Porvair Filtration Group for the effective removal of collected solids from the surface of a filter element.
Our Pulsed Jet self-cleaning gas filtration systems are used across the industry in the UK, USA and Europe, in both uranium oxide and plutonium/uranium oxide (MOX) fuel processes, including:
• Pre and post enrichment, including fluorination and defluorination
• Uranium oxide powder recovery
• Plutonium oxide powder recovery
• Pellet finishing grinding dust removal and recovery
• Process glove box venting
• High temperature fuel process, including hydrogen fluoride (HF) service
• Sintering furnace off-gas
• Plutonium and uranium powder storage vents
• Spent fuel dry store processing and vent filters
• Uranyl nitrate to trioxide conversion systems
• Reprocessing filter systems.
The back-pulse process is typically undertaken whilst the filter is in operation on-line and, apart from a very small pressure spike (or ‘overpressure’), it does not interrupt or interfere with the process flow.
