Pulse valves for reverse jet dust collectorsMany industrial manufacturing and production operations create particulates in the surrounding air. Dust collector systems are used to extract these particulates to safe levels. In a Hydraulics & Pneumatics article, Pulse Valves: An Efficient Solution, Emerson’s Michael Russo teams with Motion Industries’ Jeremiah Newton to discuss ways to lower energy and maintenance costs on these dust collection systems.

They open highlighting the stakes:

But if they [dust and particulates] aren’t effectively removed or collected, these contaminants can harm workers and damage equipment. And when contaminants are combustible, facilities may not meet related NFPA regulations or pass OSHA inspections.

As the dust collectors filters out the dusk and particulates, the:

…accumulated dust forms a dense cake that can block filters and decrease system efficiency. In reverse pulse jet dust collectors, a reverse jet bag filter cleaning system delivers a burst of compressed air that sends a shockwave through the filters, breaking up dust cakes. The dust then falls out of the collector and into a hopper.

Reverse jet back filter cleaning systems rely on pulse valves that, “…delivers the high burst of compressed air that ultimately cleans filters…”. Pulse valves such as ASCO Series 353 Solenoid Valves are diaphragm-operated solenoid valves especially designed to deliver extremely fast pulsing in reverse-jet dust collector systems. With their high flow and quick opening and closing, it helps provide extremely effective bag cleaning.

Five capabilities are important in pulse filters for longer life, easier installation and maintenance, and higher energy efficiency through reduced air consumption.

  1. High Peak Pressure
  2. Fast Valve Response Time
  3. Quick and Easy Installation
  4. Quick and Easy Maintenance
  5. Wide Temperature Performance Range

On high peak pressure, a:

…pulse valve must provide optimal peak pressure to effectively break up and remove dust cakes from filters. A pulse valve with inadequate peak pressure won’t be able to break up caked dust, leaving residue on filters. This residue makes the filters and the overall system less efficient and increases filter maintenance and costs. On the other hand, a pulse valve that provides too much pressure can prematurely wear or even tear filters.

Read the article for Michael and Jeremiah’s explanations on the other key capabilities for effective, reliable and efficient operations. They close the article by describing how pulse valves improve performance and reduce moisture to ensure pulse valve reliability.
