Abstract

Pumps are the major consumers of electricity in a process industry and filters are an integral part of the pumping process. This work discusses the reduction in energy consumption in the filtration process by using additive manufactured, geometrically optimised, conical, in-line filter supports. They are compared with those currently fabricated by more conventional means. Based on computational fluid dynamics (CFD) simulations a new filter support was designed and fabricated using Additive Manufacturing (AM) technology. The comparison was achieved by testing both types of filter supports of similar dimensions with filter mesh in a bespoke test rig of Croft Engineering Services Ltd premises. A 20 gauge, 900 µm filter mesh was used to test the two filter supports with flow rates from 0.0018 m3/s to 0.0062 m3/s. Comparison of the experimental results revealed that the additive manufactured filter support mesh arrangement was better than the conventional filter support mesh arrangement. Compared to conventional filter supports the AM filter support was 0.443kPa pressure drop lower in forward flow and 1.852 kPa lower in the reverse flow. The reduction in pressure drop reduced the energy consumption by 10kW/hr in forward flow and 29kW/hr in reverse flow.
