Converting Tumbling Hammer Rapping to Direct Plate

When explained in certain terms, electrostatic precipitators can sound like something out of science fiction. Ionized particles created through industrial processes are attracted to collection plates while cleaner air is released. The technology allows industries like yours to operate in compliance with local, state, and federal guidelines so that you can focus on working toward success.

But at the end of this amazing, scientific feat, what happens to the trapped particles? Most electrostatic precipitators have a rapping function—a method for physically separating the particles from the collection plates. But depending on your ESP’s rapping method, some of those trapped particles could be re-entrained (or re-released) back into the air.

For optimum function, compliance, and worry-free ESP usage, it may be time to consider an upgrade to your ESP’s rapping mechanism.

Tumbling Hammers and You

A tumbling hammer rapping function is exactly what it sounds like. As one of the more common rapping methods, tumbling hammers work by riding a shaft and striking the collection plates at certain, opportune times. The collected particles fall to the hopper below where they can be collected, discarded, or reused in another part of the industrial process (such as those used by paper mills).

Tumbling hammers are a reliable rapping method, but they do have their drawbacks. Tumbling hammers can funnel energy through support channels rather than directly into the plates themselves, causing accelerated wear and decreased efficiency. Furthermore, the rapper rod and collection plate may share a welded connection—a common failure in some designs.

So, when considering your options, what’s a superior rapping design method?

Direct Plate Rapping

Companies like AirTek in Troy, AL, can provide more cutting-edge rapping solutions for your electrostatic precipitator. Direct plate rapping ensures superior acceleration and maximum transfer of rapping energy into the collecting plate rather than plate support channels.

In direct plate rapping, two collection plates are rapped at a time, minimizing rapping losses and re-entrainment that can cause opacity spikes and diminished efficiency. Rapping smaller collecting plate areas requires less impact energy and, as a result, maximizes the life of the equipment. Simply put, direct plate rapping reduces maintenance costs by requiring less physical, concussive force.

Direct plate rapping has numerous other advantages and helpful features, including:

  • Maximized Transfer of Rapping Energy into Collection Plates

  • Reduced Re-entrainment

  • Optimized Precipitator Efficiency

  • Prolonged Equipment Life

  • Less Need for Regular Maintenance

  • Electromagnetic Rappers

In other areas of our lives, an “if it ain’t broke, don’t fix it,” mentality may prove wise. But when talking about the longevity, functionality, and reliability of industrial machinery, the occasional upgrade proves wiser.

Every Advantage You Can Get

You need your electrostatic precipitator to function as best it can for as long as possible. That means maximizing both efficiency and longevity. By converting your ESP to a direct plate rapping design, you can avoid untold maintenance costs and unscheduled downtime for the next decade or longer.

Heavy, expensive industrial machinery that keeps you compliant with environmental law shouldn’t be neglected or permitted to operate day-in and day-out under less than ideal circumstances. Upgrade your ESP today with AirTek’s direct plate rapping system and rest easy that you’ve done what you can to add value to your business.
