Development and Commercialization of a Grid Electrostatic Precipitator
Mr. John Dunn, Mr. James Cunningham, Dr. Xinli Jia, and Professor John McLaughlin are working on the development and commercialization of a grid electrostatic precipitator (GEP) that can be used as an energy efficient replacement for HEPA and ULPA filters in cleanrooms. An experimental version of the GEP was assembled at Cameron Manufacturing & Design, which has been supporting the project. The GEP was moved to Clarkson on March 25 and placed next to a cleanroom that Cameron will donate to Clarkson. Testing of the GEP began during the week of March 29. The cleanroom has been assembled in the Saint Lawrence County Industrial Development Agency's Building in Potsdam. The goal of the cleanroom experiments will be to determine the potential of the GEP as a substitute for HEPA and ULPA filters. The efficiency of catalyst particles at removing ozone created by the corona discharge will also be evaluated in the experiments. After making suitable modifications that will be guided, in part, by computer simulations of the air flow and particle trajectories inside the GEP, the GEP will be transferred to a cleanroom at Infotonics Technology Center in Canandaigua, NY. At Infotonics, the GEP will be used to replace one or more HEPA filters in a clean- room, and the particle concentration and size distribution in the room will be measured. The project is being funded by Cameron through a grant to Clarkson and by a matching grant from CAMP. The project team recently received additional funding through a Commercialization Assistance Program (CAP) grant from the Syracuse Center of Excellence and the Syracuse Metropolitan Development Agency. Mr. Dunn is an inventor who is a consultant for Cameron Manufacturing and a Research Scientist at Clarkson University. Mr. Cunningham is a Business Developer/Principal Consultant with Alliance for Manufacturing & Technology, which is located in Binghamton, NY. Dr. Jia is a Post-Doctoral Research Associate at Clarkson.
The grid electrode precipitator (GEP) is shown next to the cleanroom where it will be tested. The GEP has three sections: (1) a pre-charger that facilitates agglomeration of particles into larger particles; (2) the main collection section in which the particles are re-charged and collected on grounded surfaces; (3) a final section at the top which contains a catalyst that removes ozone. Air will be drawn into the bottom of the GEP from the bottom of the cleanroom and returned to the ceiling vents.
