When dealing with dust collection systems, it is critical to regularly clean the collected dust out of the equipment. One of the methods to remove the accumulated dust is with the help of vibration. Where the vibration is applied, though, depends on the collection system installed. Standard installations that we see are:

• Electrostatic Precipitators (ESP)
• Baghouses
• Cyclones

Electrostatic Precipitators

First, we’ll discuss electrostatic precipitators. These are large systems that are frequently found at facilities, such as:

The systems have a series of wires and plates that act as filters that rely on an electrostatic charge to pull dust particles from the air passing through the collection system. Keeping these wires and plates clean is imperative to the process because it helps increase the efficiency of the dust collection system.

This is where a Rapper comes into play.

The Cleveland Vibrator 3″ PMA Rapper is an air-powered piston vibrator that is installed on a mounting plate connected to a shaft to shake the wires and plates. This shaking process breaks the friction of the particulates clinging to the collection media. The dust then drops down to the collection hopper underneath. Once the material is in the collection hopper, an externally mounted piston vibrator or air knocker will remove the dust from the inside sloped walls of the hopper and to the discharge.
