What is Dust collector and how it work?

A Dust Collector is used to extract dust particles out of the air. In most cases these are used as part of a larger Dust Collection System. Normally the dirty air will be sucked into an inlet in the duct work, from there it will flow into the Collector where the dust laden gas stream (most often Air) will have the contaminates filtered out, before passing the now clean gas stream out, either for further processing, to be recirculated in the facility, or discharged into the atmosphere.

There are several different kinds of Dust Collectors, the most common being Fabric Collectors such as a Baghouse. In this design the air is cleaned by passing it through a number of Filter Bags that capture the dust and allow the air to pass through. Another popular design is a Cyclone Collector, where the incoming air is forced by the design of the duct work to spin at a high speed causing the majority of the larger particles to be thrown to the outside of the cone, where it then falls to the bottom to be collected later. There are also Wet Scrubberswhere the air is passed through an environment that is full of a fine mist, or vapor that allows for the water (or other subbing liquid) to stick to the dust particles causing them to fall to the bottom. In an Electrostatic Presipitator the contaminated gas stream is passed between to electodes that Ionize the air causing the dust particles to carry an electrical charge. The now Electrically charged air is then passed by another set of electric plates with an opposing charge that attracts the particles to it, thereby cleaning the air.

These are a few of the main Dust Collector design types that you will find in use today. They each have their advantages and disadvantages. For each unique application certain types are better suited then others. A qualified expert in the field can help you to determine what kind of collector will fit your needs the best.
