A hybrid filter system has been developed as an air pollution control device that closely integrates electrostatic precipitation (ESP) and fabric filter technologies into a durable, cost-effective device that produces superior filtration results. Its design uses a synergy between these two technologies whereby the filter bags are able to operate at high air-to-cloth (A/C) ratios than conventional pulse jet fabric filters. Since the hybrid filter can be operated at high A/C ratios, less fabric filter components such as filter bags, filter cages, and pulse valves are needed. This allows the use of higher performance and more durable components and translates into a more reliable system that requires less overall maintenance. The net result is a cost-effective system that offers the reliability of an ESP with the filtration performance of a fabric filter.
This filter technology is easily adapted to new installations as well as retrofits of existing ESPs.
