A ‘Sound’ Solution to Material Flow Problems

By Donald F. Cameron Primasonics International Ltd. |

Particulate buildup and other material flow problems are common hurdles wherever dry materials find application in the chemical process industries (CPI). Since manual intervention is costly in terms of downtime, and can be quite hazardous for the personnel involved, dedicated equipment is an attractive way to either prevent or remove flow blockages. Equipment options include vibrators and air cannons and a lesser-known, yet sound solution known as audiosonic acoustic cleaners (AACs). About AACs AACs employ high-energy, low-frequency sound waves to eliminate particulate buildup and facilitate maximum material flow. Also known as sonic horns (Figure 1), these pneumatically operated devices generally produce sound waves within the 60–420 Hz frequency range. Figure 1. AACs are offered in a wide variety of sizes. Larger models are offered in either straight or curved designs AACs are non-intrusive, and can be employed wherever ash, dust, powders or granular materials are processed, generated, stored or transported. Reasons for installation generally echo the CPI’s top priorities: Safety:Avoid the necessity for personnel to enter process equipment by providing constant, safe, remote cleaning. Environment:Reduce opacity spiking…
