A DEVICE FOR GENERATING ACOUSTIC AND/OR VIBRATION ENERGY FORHEAT EXCHANGER TUBES

摘要

A device is coupled to a heat exchanger for mitigating fouling by applyin g a mechanical force to a fixed heat exchanger to excite a vibration in the heat exchange surface and produce shear waves in the fluid adjacent the heat exchange surface while the heat exchanger is in operation. An electromagnet ic driven impulse device induces vibration onto heat exchanger tubes and/or an acoustic wave through the liquid service fluid to reduce fouling. The dev ice can be mounted directly onto the outer part or piping and produces acous tical/vibrational modes onto the tube or near the surface of tubes.
