We're sometimes asked whether our triboelectric detection systems work with all types of dust collectors or only with “baghouses”. When we're asked, we normally step back a bit to discuss what dust collectors are exactly and how we speak about them. So if you've ever wondered, here's a brief description on the differences between dust collector styles and where you commonly see them.
Yes, Triboelectric Bag Leak Detection Systems Work with EVERY Type of Dust Collector
Simply put, our bag leak detection systems work with any kind of dust collection system in use today and even with legacy units no longer in production. Part of the confusion may stem from the use (or overuse or outright misuse) of specific industry terms and resulting misunderstandings.
The Major Types of Dust Collectors
A DUST COLLECTOR is a machine used to filter dust particles from an airstream, usually in an industrial facility. Many kinds of dust collectors are used today and many different styles have come and gone over the last 150 years. There are four major categories of dust collectors that use different methods to remove dust from the air.
- CYCLONE COLLECTORS force the incoming air into a spinning motion (like a tornado) and use centrifugal force to throw the dust particles out of the air into the side of the unit where it then drops out. These units, while not efficient enough to be used alone in most applications, work well for large particles and are used as “precleaners” to lighten the dust loads for other more efficient collectors further downstream.
- WET SCRUBBERS (sometimes called wet dust collectors) pass the air through water often mixed with other chemicals to remove particles from the air. These are frequently used to remove certain gases such as Nitric Oxides and Sulfur Dioxides. They are not efficient enough to be the sole dust collector in most applications and have problems dealing with large quantities of dust as handling of the scrubbing fluid can be complex.
- ELECTROSTATIC PRECIPITATORS use large electrically-conductive plates to charge the dust particles contained in the passing air, which are then attracted to and collected on negatively charged plates at the end of the unit. These once were widely used in very large applications such as power plants, foundries or cement plants, but are increasingly unable to meet newer emissions standards.
- FABRIC FILTER DUST COLLECTORS pass air through a fabric filter, capturing the dust and allowing the air to pass through. These are by far the most common type of dust collectors used today. They are the most efficient, versatile, and have the widest range of applications. While all fabric collectors operate on the same basic principle described above, there are several different styles of collectors that employ different styles of fabric filters in various configurations. Since the most common are bag filters a fabric filter collector is very often referred to as a “BAGHOUSE”.
- A common variation is the CARTRIDGE FILTER DUST COLLECTOR, which replaces the simple bag-shaped filters with a one piece cartridge. These are commonly used to collect very fine dusts such as fumes, mists, or smoke but are not suitable for applications with large amounts of dust.
- Newer technology has blended the bag and cartridge styles together into what is called a PLEATED FILTER ELEMENT or simply PLEATED BAGHOUSE FILTERS. These are essentially one-piece cartridges that can be used in a normal baghouse with little to no modification. They combine the best of both baghouses and cartridge collectors into one and have seen wide acceptance across many applications.
Every Type of Dust Collector Can Benefit From Triboelectric Detector Technology
Regardless of what kind of dust collector is used by a facility, all can benefit from using triboelectric dust monitoring systems. By providing reliable emissions data in real-time, operators can see when collectors begin experiencing problems and avoid production shutdowns. Maintenance personnel can receive early warning of impending filter failure, thus gaining the predictive maintenance capability to schedule changeouts at the most opportune time. Finally, compliance and environmental personnel can easily collect all relevant emissions data for their reports and keep careful watch over their plant’s ability to abide by its air permits.
