Automatic diagnostic controls for tough pulse-jet baghouse applications

This article describes how equipping your pulse-jet baghouse with an automatic diagnostic control system can boost your bottom line in tough applications. Sections cover how the system works and how to calculate the system’s return on investment compared with standard pulse-jet filter-cleaning control systems.

A pulse-jet baghouse is ideal for controlling dust in many bulk solids processing plants. In the baghouse, rows of bag filters are suspended from a tubesheet and cleaned at intervals by pulses of compressed air that are directed down into each filter. The pulsing action dislodges the dust on the filter, causing the particles to fall into the baghouse's hopper for collection and recycling to the process or disposal. Most baghouses have one of two filter-cleaning control systems: a pulse-on-demand system that pulses the filters based on a preset baghouse pressure-drop reading, or a continuous-pulse system that activates the pulses at a timed interval. For some tough applications, however, these systems aren’t enough to keep the baghouse operating at peak levels.
