Allied Environmental Technologies, Inc. had been developing a novel Multi-Stage Collector (MSC™) technology for ultra-high efficiency removal of the ultra-fine particulate matter. The MSC™ concept is a patented process (Krigmont, US Pat. 6,524,369 and US Pat. 6,932,857) that entails a unique integration of electrostatic precipitation and barrier filtration of particulate.
The multi-stage collector (MSC™) is a new concept for particulate control. The intent of the MSC™ is to combine the best features of the two-stage ESP and a FF in a manner that has not been done before. The MSC™ concept can be broadly summarized as a system in which multiple stages are utilized, where each stage performs its primary function, and the multiple stages operate synergistically to provide significantly improved overall performance.
The principal objective of the MSC™ is to substantially improve fine particulate collection by combining both electrostatic charging/collection and filtration processes. It separates zones for particle charging and collecting, thus providing a new unique collector design with improved efficiency to collect high resistance fine dust particles.
The MSC™ consists of a superbly compact multi-stage collector for collecting dust, fume, etc. for industrial gases, which is independent of electrical resistivity. Therefore, it will be especially beneficial when electrical resistivity of such dust or fume as precipitated, exceeds 10 to the power of 11 Ohm-cm or is extremely low, for example less than 10 to the power of 4 Ohm-cm. Furthermore, this design will be particularly advantageous when the material to be collected consists mostly of a sub-micron and ultra-fine dust or fume. It also could be easily integrated with various catalysts for multitude of the gaseous pollutants collection.
•MSC™ is suitable for the new installations or as a retrofit replacement technology for existing particulate collectors as well as an add-on retrofit technology.
•MSC™ solves the problem of excessive fine-particle emissions with conventional technologies.
•MSC™ greatly reduces the problem of higher fine particulate emissions from conventional baghouses.
•MSC™ solves the problem of reentrainment and recollection of dust in conventional pulsejet baghouses caused by the close bag spacing and the effect of cleaning one row of bags at a time.
•MSC™ requires significantly less total collection/filter area than conventional ESPs and baghouses.
•MSC™ requires significantly less footprint area than conventional ESPs or baghouses.
•MSC™ overcomes hurdles that prevent operation at high FV ratios.
•MSC™ reduces the applicability problem for ESPs with high-resistivity dusts.
•MSC™ requires significantly less filter surface area than conventional fabric filter.
